General notes 25
You could jeopardise the operating safety of your vehicle if you use parts, tyres and wheels as well as accessories relevant to safety which have not been approved by Mercedes-Benz. Safety-relevant systems, e.g. the brake system, may malfunction. Only use Mercedes-Benz GenuineParts or parts of equal quality. Only use tyres, wheels and accessory parts that have been speci cally approved for your vehicle model.
Mercedes-Benz tests original parts and conversion parts and accessory parts that have been speci cally approved for your vehicle model for their reliability, safety and suitability. Despite ongoing market research, Mercedes-Benz is unable to assess other parts. Mercedes-Benz therefore accepts no responsibility for the use of such parts in Mercedes-Benz vehicles, even if they have been o cially approved or independently approved by a testing centre.
Certain parts are only o cially approved for installation or modi cation if they comply with legal requirements. All Mercedes-Benz GenuineParts meet the approval requirements. The use of non-approved parts may invalidate the vehicle's general operating permit.

26 General notes

28 General notes
* NOTE Damage to the vehicle due to driving too fast and due to impacts to the vehicle underbody or suspension components
In the following situations, in particular, there is a risk of damage to the vehicle:
R the vehicle becomes grounded, e.g. on a high kerb or an unpaved road
R the vehicle is driven too fast over an obstacle, e.g. a kerb, speed bump or pothole
R a heavy object strikes the underbody or suspension components
In situations such as these, damage to the body, underbody, suspension components, wheels or tyres may not be visible. Components damaged in this way can unexpectedly fail or, in the case of an accident, may no longer absorb the resulting force as intended.
If the underbody panelling is damaged, ammable materials such as leaves, grass or twigs can collect between the underbody and the underbody panelling. These materials may

ignite if they come into contact with hot parts of the exhaust system.
# Have the vehicle checked and repaired immediately at a quali ed specialist workshop.

Data storage
Data processing in the vehicle
Electronic control units Electronic control units are tted in your vehicle. Control units process data which, for example, they receive from vehicle sensors, generate themselves or exchange between themselves. Some control units are required for the safe operation of your vehicle, some assist you when driving, such as driver assistance systems, while others enable convenience or infotainment functions.
The following provides you with general information regarding data processing in the vehicle. Additional information regarding exactly which data in your vehicle are collected, saved and transmitted to third parties, and for what purpose, can be found in the information directly related to the functional characteristics in question in their respective operating instructions. This information is also available online and, depending on the vehicle equipment, digitally.

Personal data Every vehicle is identi ed by a unique vehicle identi cation number. Depending on the country, this vehicle identi cation number can be used by, for example, governmental authorities to determine the identity of the owner. There are other possibilities to use data collected from the vehicle to identify the owner or driver, such as the licence plate number.
Therefore, data generated or processed by control units may be attributable to a person or, under certain conditions, become attributable to a person. Depending on which vehicle data are available, it may be possible to make inferences about, for example, your driving behaviour, your location, your route or your use patterns.
Legal requirements regarding the disclosure of data If legally required to do so, manufacturers are, in individual cases, legally obliged to provide governmental entities, upon request and to the extent required, data stored by the manufacturer. For example, this may be the case during the investigation of a criminal o ence.

Governmental entities are themselves, in individual cases and within the applicable legal framework, authorised to read out data from the vehicle. In the case of an accident, information that can help with an investigation can, therefore, be taken from the airbag control unit, for example.
Operational data in the vehicle This is data regarding the operation of the vehicle, which have been processed by control units.
This includes the following data, for example:
R vehicle status information such as the speed, longitudinal acceleration, lateral acceleration, number of wheel revolutions or the fastened seat belts display
R ambient conditions, such as temperature, rain sensor or distance sensor
Generally, the use of these data is temporary; they will not be stored beyond the period of operation and will only be processed within the vehicle itself. Control units o en contain data memories for vehicle keys, for example. Their use permits the temporary or permanent documentation of technical information about the vehicle's operat-

General notes 43

ing state, component loads, maintenance requirements and technical events or faults.
Depending on the vehicle equipment, the following data are stored:
R operating status of system components, such as ll levels, tyre pressure or battery status
R malfunctions or faults in important system components, such as lights or brakes
R system reactions in special driving situations, such as airbag deployment or the intervention of stability control systems
R information on events leading to vehicle damage
In certain cases, it may be required to store data that would have otherwise been used only temporarily. This may be the case if the vehicle has detected a malfunction, for example.
If you use services, such as repair services and maintenance work, stored operational data as well as the vehicle identi cation number can be read out and used. They can be read out by service network employees, such as workshops and manufacturers or third parties, such as break-

down services. The same is true in the case of warranty claims and quality assurance measures.
In general, the readout is performed via the legally prescribed port for the diagnostics connection in the vehicle. The operational data that are read out document technical states of the vehicle or of individual components and assist in the diagnosis of malfunctions, compliance with warranty obligations and quality improvement. To that end, these data, in particular information about component loads, technical events, malfunctions and other faults may be transmitted along with the vehicle identi cation number to the manufacturer. Furthermore, the manufacturer is subject to product liability. For this reason the manufacturer also uses operational data from the vehicle, for example, for recalls. These data can also be used to examine the customer's warranty and guarantee claims.
Fault memories in the vehicle can be reset by a service outlet or at your request as part of repair or maintenance work.

Convenience and infotainment functions You can store convenience settings and individual settings in the vehicle and change or reset them at any time.
Depending on the vehicle equipment, this includes the following settings, for example:
R seat and steering wheel positions
R suspension and climate control settings
R individual settings, such as interior lighting
Depending on the selected equipment, you can import data into vehicle infotainment functions yourself.
Depending on the vehicle equipment, this includes the following data, for example:
R multimedia data, such as music, lms or photos for playback in an integrated multimedia system
R address book data for use in connection with an integrated hands-free system or an integrated navigation system
R entered navigation destinations
R data about the use of Internet services

44 General notes

These data for convenience and infotainment functions may be saved locally in the vehicle or they may be located on a device which you have connected to the vehicle, such as a smartphone, USB ash drive or MP3 player. If you have entered these data yourself, you can delete them at any time.
This data is transmitted from the vehicle to third parties only at your request. This applies, in particular, when you use online services in accordance with the settings that you have selected.
Smartphone integration (e.g. Android Auto or Apple CarPlay®) If your vehicle is accordingly equipped, you can connect your smartphone or another mobile end device to the vehicle. You can then control them by means of the control elements integrated in the vehicle. Images and audio from the smartphone can be output via the multimedia system. Certain information is simultaneously transferred to your smartphone. Depending on the type and integration, this includes position data, day/night mode and other general vehicle statuses. For more information please consult the Owner's Manual of the vehicle/infotainment system.

This integration allows the use of selected smartphone apps, such as navigation or music player apps. There is no further interaction between the smartphone and the vehicle; in particular, vehicle data is not directly accessible. The type of additional data processing is determined by the provider of the app being used. Which settings you can make, if any, depends on the speci c app and the operating system of your smartphone.
Online services
Wireless network connection If your vehicle has a wireless network connection, it enables data to be exchanged between your vehicle and additional systems. The wireless network connection is made possible by the vehicle's own transmitter and receiver or by a mobile end device that you have brought into the vehicle, for example, a smartphone. Online functions can be used via the wireless network connection. This includes online services and applications/apps provided to you by the manufacturer or by other providers.

Manufacturer's services Regarding the manufacturer's online services, the individual functions are described by the manufacturer in a suitable place, for example, in the Owner's Manual or on the manufacturer's website, where the relevant data protection information is also given. Personal data may be used for the provision of online services. Data are exchanged via a secure connection, such as the manufacturer's designated IT systems. Any personal data which are collected, processed and used, other than for the provision of services, is done so exclusively on the basis of legal permission. This is the case, for example, for a legally prescribed emergency call system, a contractual agreement or when consent has been given.
You can have services and functions, some of which are subject to a fee, activated or deactivated. This excludes legally prescribed functions and services, such as an emergency call system.
Third party services If you use online services from other providers (third parties), these services are the responsibility of the provider in question and subject to that provider's data protection conditions and terms of

use. As a general rule, the manufacturer has no in uence on the content exchanged.
For this reason, when services are provided by third parties, please ask the service provider in question for information about the type, extent and purpose of the collection and use of personal data.

Copyright
Information on licences for free and open-source so ware used in your vehicle can be found on the data carrier in your vehicle document wallet and with updates on the following website:

Data protection rights
Depending on your country or the equipment and range of functions of your vehicle as well as the services you use and the services on o er, you are entitled to di erent data protection rights. Further information on data protection and your data protection rights can either be found on the manufacturer's website or you will receive this information as part of the various services and service o ers. There you will also nd the contact information for the manufacturer and its data protection o cers.
At a workshop, for example, with the support of a specialist and possibly for a fee, you can have data read out which is stored only locally in the vehicle.

General notes 45

46 Occupant safety

Restraint system
Protection provided by the restraint system
The restraint system includes the following components:
R Seat belt system
R Airbags
R Child restraint system
R Child seat securing systems
The restraint system can help prevent the vehicle occupants from coming into contact with parts of the vehicle interior in the event of an accident. In the event of an accident, the restraint system can also reduce the forces to which the vehicle occupants are subjected.
A seat belt can only provide the best level of protection if it is worn correctly. Depending on the detected accident situation, seat belt tensioners and/or airbags supplement the protection o ered by a correctly worn seat belt. Seat belt tensioners and/or airbags are not deployed in every accident.

In order for the restraint system to provide the intended level of protection, each vehicle occupant must observe the following information:
R Fasten seat belts correctly.
R Sit in an almost upright seat position with their back against the seat backrest.
R Sit with their feet resting on the oor, if possible.
R Always secure persons under 1.50 m tall in an additional restraint system suitable for Mercedes-Benz vehicles.
However, no system available today can completely eliminate injuries and fatalities in every accident situation. In particular, the seat belt and airbag generally do not protect against objects penetrating the vehicle from the outside. It is also not possible to completely rule out the risk of injury caused by the airbag deploying.

Limitations of the protection provided by the restraint system
& WARNING Risk of injury or death due to modi cations to the restraint system
Vehicle occupants may no longer be protected as intended if alterations are made to the restraint system.
# Never alter the parts of the restraint system.
# Never tamper with the wiring or any electronic component parts or their so ware.
If it is necessary to modify the vehicle to accommodate a person with disabilities, contact a qualied specialist workshop.
Mercedes-Benz recommends that you use driving aids which have been approved for your vehicle by Mercedes-Benz.

Restraint system functionality
When the vehicle is switched on, a self-test is performed, during which the 6 restraint system warning lamp lights up. It goes out no later than a few seconds a er the vehicle is started. The components of the restraint system are then functional.
Malfunctioning restraint system
A malfunction has occurred in the restraint system if: R the 6 restraint system warning lamp does
not light up when the vehicle is switched on R the 6 restraint system warning lamp lights
up continuously or repeatedly during a journey
All vehicles, except plug-in hybrid:
& WARNING Risk of injury due to malfunctions in the restraint system
Components in the restraint system may be activated unintentionally or not deploy as intended in an accident.

# Have the restraint system checked and repaired immediately at a quali ed specialist workshop.
Plug-in hybrid:
& DANGER Risk of fatal injuries due to restraint system malfunctions
Components in the restraint system may be activated unintentionally or not deploy as planned in an accident. In the event of an accident, the high-voltage on-board electrical system may not be deactivated as intended.
You may su er an electric shock if you touch the damaged components of the high-voltage on-board electrical system.
# Have the restraint system checked and repaired immediately at a quali ed specialist workshop.
# A er an accident, switch o the vehicle immediately.

Occupant safety 47
Function of the restraint system in an accident
How the restraint system works depends on the severity of the impact detected and the apparent type of accident:
R Frontal impact
R Rear impact
R Side impact
R Only for certain countries: rollover
The activation thresholds for the components of the restraint system are determined based on the evaluation of the sensor values measured at various points in the vehicle. This process is pre-emptive in nature. The triggering/deployment of the components of the restraint system must take place in good time at the start of the collision.
Factors which can only be seen and measured a er a collision has occurred cannot play a decisive role in airbag deployment. Nor do they provide an indication of airbag deployment.
The vehicle may be deformed signi cantly without an airbag being deployed. This is the case if only parts which are relatively easily deformed are a ected and the rate of vehicle deceleration is

48 Occupant safety
not high. Conversely, an airbag may be deployed even though the vehicle su ers only minor deformation. If very rigid vehicle parts such as longitudinal members are hit, this may result in su ciently high levels of vehicle deceleration.
Depending on the detected deployment situation, the components of the restraint system can be activated or deployed independently of each other:
R Seat belt tensioner: frontal impact, rear impact, side impact, rollover1
R Driver's airbag, front passenger airbag: frontal impact
R Knee airbag: frontal impact
R Side airbag: side impact
R Window airbag: side impact, rollover1, frontal impact
1) Only for certain countries.
The front passenger airbag can only be deployed in an accident if the PASSENGER AIR BAG OFF indicator lamp is o . If the front passenger seat is occupied, make sure, both before and during the

journey, that the status of the front passenger airbag is correct (/ page 57).
& WARNING Risk of burns from hot airbag components
The airbag parts are hot a er an airbag has been deployed.
# Do not touch the airbag parts.
# Have a deployed airbag replaced at a quali ed specialist workshop as soon as possible.
Mercedes-Benz recommends that you have the vehicle towed to a quali ed specialist workshop a er an accident. Take this into account, particularly if a seat belt tensioner is triggered or an airbag deployed.
If the seat belt tensioners are triggered or an airbag is deployed, you will hear a bang, and a small amount of powder may also be released:
R The bang will not generally a ect your hearing.

62 Occupant safety

To improve protection for children younger than 12 years old or under 1.50 m in height, Mercedes-Benz recommends you observe the following information:
R Always secure the child in a child restraint system suitable for this Mercedes-Benz vehicle.
R The child restraint system must be appropriate to the age, weight and size of the child.
R The vehicle seat must be suitable for tting a child restraint system (/ page 66).
Accident statistics show that children secured on the rear seats are generally safer than children secured on the front seats. For this reason, Mercedes-Benz strongly advises that you t a child restraint system to a rear seat.
The generic term child restraint system
The generic term child restraint system is used in this Owner's Manual. A child restraint system is, for example:
R a baby car seat
R a rearward-facing child seat
R a forward-facing child seat

R a child booster seat with a backrest and seat belt guide
Mercedes-Benz recommends using a child booster seat with a backrest.
The child restraint system must be appropriate to the age, weight and size of the child.

Fitting the ISOFIX or iSize child restraint system on the le and right rear seats
& WARNING Risk of accident if the rear bench seat, rear seat and seat backrest are not engaged
The rear bench seat, rear seat and seat backrest may fold forwards, even while the vehicle is in motion.
R As a result, the vehicle occupant will be pressed into the seat belt with increased force. The seat belt will not be able to protect as intended and could cause additional injury.
R Objects or loads in the boot or load compartment cannot be restrained by the seat backrest.
# Make sure that the rear bench seat, the rear seat and the seat backrest are engaged before every trip.
If the le and right seat backrests are not engaged and locked in place, this will be shown on the display on the instrument cluster.

If the centre seat backrest is not engaged and locked in place, the red lock veri cation indicator will be visible.
& WARNING Risk of injury or death if the permissible gross mass of the child and child restraint system together is exceeded.
Too much load may be placed on the ISOFIX or iSize child restraint systems and the child may not be restrained correctly in the event of an accident, for example.
# If the child and the child restraint system together weigh more than 33 kg, only use an ISOFIX or iSize child restraint system with which the child is secured with the vehicle seat belt.
# Also secure the child restraint system with the Top Tether belt, if available.

Always comply with the information about the mass of the child restraint system:
R in the manufacturer's installation and operating instructions for the child restraint system used
R on a label on the child restraint system, if present
Regularly check that the permissible gross mass of the child and child restraint system is still complied with.
When tting a child restraint system, observe the following:
O Always observe the correct use of the seats and consider their suitability for attaching a child restraint system.
ISOFIX child seat securing system (/ page 68)
or

O Always comply with the manufacturer's installation and operating instructions for the child restraint system used.
O Make sure that the child's feet do not touch the front seat. If necessary, move the front seat slightly forwards.
® When tting an ISOFIX child restraint system, also observe the following:
O When using a baby car seat in weight group 0/0+ and a rearward-facing child restraint system in weight group 1 on a rear seat: adjust the front seat so that the seat does not touch the child restraint system.
O When using a forward-facing child restraint system in weight group 1: remove the head restraint from the respective seat, if possible. In addition, the backrest of the child restraint system must lie as at as possible against the backrest of the vehicle seat.
A er the child restraint system has been removed, replace the head restraint immediately and adjust all head restraints correctly.

Occupant safety 71
O If the head restraint of the child seat cannot be fully extended when it is installed in the vehicle, this will result in restrictions on the maximum size setting for child restraint systems in weight group 2 or 3.
Contact with the roof when the head restraint is fully extended and locked in place will not result in any restrictions on use.
O The child restraint system must not be put under strain between the roof and the seat cushion and/or be tted facing the wrong direction. Where possible, adjust the seat cushion inclination accordingly.
O The child restraint system must not be put under strain by the head restraint. Adjust the head restraints as appropriate.
° When tting an iSize child restraint system, also observe the following:
O When using a rearward-facing child restraint system: adjust the front seat so that it does not touch the child restraint system.
O When using a forward-facing child restraint system: remove the head restraint from the
