Wheel Change

Safety Precautions for Wheel Change

Before lifting the vehicle or changing a wheel, read and follow these instructions:

• Always choose a safe place to stop – away from highways and traffic flow.
• The vehicle and the jack supporting it must be on a firm, level surface.
• Engage the parking brake and shift the selector lever into the Park (P) position.
• Ensure the air suspension is set to the normal vehicle height.
• Turn on the hazard warning lights.
• Ensure the front wheels are positioned straight ahead.
• Disconnect any trailer from the vehicle.
• Ensure there are no passengers or animals in the vehicle, and that they are in a safe location away from the road.
• Place the warning triangle at the required distance behind the vehicle, with the reflective side facing oncoming traffic.

Tool Kit

Note: The types and location of tools may differ from those shown in the illustrations.

• Floor panel of the luggage compartment.
• Jack.
• Spare wheel lift.
• Tool kit - located under the spare wheel. See 284, REMOVING THE SPARE WHEEL.

Note: Periodically inspect the jack, clean and lubricate the moving parts, especially the lifting screw, to prevent corrosion.

Note: Pay special attention to the correct placement of each tool, as it must be returned to its place after use.

Removing the Spare Wheel

• Remove the spare wheel before lifting the vehicle to avoid affecting the stability of the raised vehicle.
• Wheels are very heavy, so improper handling can lead to injury. Take special precautions when lifting, lowering, and moving wheels.
• Always secure the spare or removed wheel in its correct position with a retaining bolt.
• Do not install the wheel in its recess while the vehicle is raised by the jack.
• After changing the wheel, always secure the tools, chocks, jack, and the changed wheel in their storage locations. If not properly secured, these items can dislodge during a collision or rollover, potentially causing injury or death.

Always remove the spare wheel before lifting the vehicle.

Note: Before removing the spare wheel, note its storage position. The replacement wheel must be correctly positioned and secured in its storage location.

1. Open the luggage compartment door. See 9, OPENING AND CLOSING THE LUGGAGE COMPARTMENT DOOR.
2. Remove the luggage compartment floor panel.
3. Remove the spare wheel retaining bolt.
4. Remove the vehicle jack and the spare wheel lift. See 283, TOOL KIT.
5. Secure the lift as shown in the illustration.
• Pull the upper strap to lift the spare wheel.
• Pull the lower strap to place the spare wheel on the luggage compartment door.
6. Remove the tool and carefully lift the spare wheel from the vehicle.

Note: To store the replaced wheel, perform this procedure in reverse.

Using Wheel Chocks

• Before lifting the vehicle, block the wheel diagonally opposite the one being removed with chocks.
• Always block the wheels using suitable wheel chocks.
• Place the chocks on both sides of the wheel diagonally opposite the wheel being replaced.
• If you need to lift the vehicle with the jack on a slope, place the chocks on the downhill side, positioning them under both wheels of the axle that is not being lifted.

Wheel chocks are stored in the tool kit.

1. Remove the chocks from the tool kit.
2. Slightly spread the two halves and turn until fully extended to increase the wedge.
3. Position the vehicle on a level surface.

Both chocks must be used. Place them on both sides of the wheel and slide them firmly under the wheel.

Wheel Lug Nut Fastening

Wheel lug nuts can only be removed and installed using the special adapter from the tool kit.

Note: When a new vehicle is delivered, the adapter may be in the glove compartment. It should be placed in the tool kit immediately.

Note: The code number is stamped on the underside of the adapter. Record this number in the service booklet included with the vehicle documentation. This number will be required when ordering a replacement adapter.

To unscrew:

1. Insert the adapter securely into the wheel's locking lug nut.
2. Place the lug wrench onto the adapter and turn the wheel nut half a turn counterclockwise.
3. After lifting the vehicle with the jack, unscrew the locking nut.

Note: After use, place the wheel lug nut adapter in its designated location in the tool kit.

Wheel Replacement

Before lifting the vehicle or changing a wheel, read and follow these instructions:

• Ensure the jack is on a firm, level surface.
• Do not place anything between the jack and the ground, or between the jack and the vehicle.
• Position the jack on the side of the vehicle, aligned with the correct jacking point.
• Do not lift the vehicle until the jack base is seated in the jack point.
• Use the jack only in the designated jacking points.
• WARNING – DO NOT PLACE ANY PART OF YOUR BODY COMPLETELY OR PARTIALLY UNDER A VEHICLE SUPPORTED ONLY BY A JACK.
• The jack is intended for wheel changing only. Do not be under the vehicle if the jack is the only support. Always place suitable capacity support stands under the vehicle before starting work under it.
• When changing tires, always use the jack with its handle assembled to reduce the risk of injury.

• Observe precautions when loosening wheel nuts. If the lug wrench is not fitted correctly, it could slip, and the nut could suddenly turn. Furthermore, sudden movement could cause injury.
• Do not start the engine or leave the vehicle running while it is supported only by the jack.
• Use only the jacking points indicated below to avoid the risk of damaging the vehicle.

Note: The vehicle may be equipped with a tilt sensor that activates an alarm if the vehicle tilts in any direction after locking. To prevent the doors from locking during a wheel change, you can temporarily disable the tilt sensor. See 74, INSTRUMENT PANEL MENU.

Note: If side steps or running boards are fitted, the jacking points are located on the underside of the side step or running board brackets.

Before lifting the vehicle using the lug wrench, loosen the wheel nuts of the wheel to be replaced by half a turn counterclockwise.

1. Position the jack under the correct jacking point.

Note: Do not allow the jack to contact the sill at any other point, as this could cause damage.

1. Turn the jack handle clockwise to raise the jack until the jack pin enters the recess. Ensure the jack base is fully supported by the ground.
2. Slowly and evenly raise the vehicle with the jack. Avoid quick, jerky movements that could cause the vehicle/jack to lose stability.
3. Remove the wheel nuts and place them in a secure location where they cannot roll away.
4. Remove the wheel and set it aside. Do not place the wheel face down, as this may damage the finish.
5. Install the temporary spare wheel onto the hub.
6. Reinstall the wheel nuts and tighten them slightly. Ensure the wheel is seated evenly on the hub.
7. Once you have confirmed there are no obstructions under the vehicle, slowly and evenly lower the vehicle.
8. After all wheels are on the ground, remove the jack and fully tighten the wheel lug nuts. Tighten the wheel lug nuts in the sequence shown in the illustration to a torque of 133 Nm (98 lb-ft).

Important Information - Using the Spare Wheel

Note: If it was not possible to measure the wheel nut tightening torque immediately upon replacement, they must be tightened to the specified torque as soon as possible.

If a spare wheel with an alloy rim is to be fitted, use a suitable blunt tool to knock off the center cap from the removed wheel. Install the center cap removed in this manner into the replacement wheel by pushing it in by hand.

Check and adjust the tire pressure as soon as possible.

• Always strictly follow the instructions for using the temporary spare wheel as indicated on its label. Failure to follow the instructions may be hazardous.
• The temporary spare wheel (if fitted) is for TEMPORARY USE ONLY. If a temporary spare wheel is fitted, drive with caution. Install a full-size wheel and tire at the earliest opportunity.
• Do not install more than one temporary spare wheel on the vehicle at the same time.
• Do not exceed a speed of 80 km/h (50 mph) when driving with a temporary spare wheel fitted.
• The pressure in the temporary spare wheel must be 4.2 bar (60 psi or 420 kPa).

When fitting the temporary spare wheel, the DSC system should be activated.

Do not fit anti-skid devices, such as snow chains, to the temporary spare wheel.
