Setup and Installation
The Cybex Aton G Infant Car Seat comes with a SAFELOCK base for secure and easy installation. This car seat is designed for rear-facing use only.
Installing the SAFELOCK Base
The SAFELOCK base can be installed using the vehicle's LATCH system. Ensure the base is level and securely fastened, with minimal movement.

Attaching the Car Seat to the Base
Once the base is securely installed, align the car seat with the base and push down firmly until you hear an audible "click," indicating it is locked into place. Always check the connection by pulling up on the car seat.
Newborn Insert
The car seat includes a removable newborn insert designed to provide proper support and positioning for infants up to a certain weight (refer to the full manual for specific weight limits). Install the insert before placing a newborn in the seat. Remove it when your child outgrows it to ensure proper harness fit.
Operating Instructions
Adjusting the Headrest and Harness
The Cybex Aton G features an 11-position adjustable headrest with a no-rethread harness. To adjust, squeeze the headrest adjustment handle (usually located at the back or top of the headrest) and slide the headrest up or down to the desired position. Ensure the harness straps are at or slightly below your child's shoulders for rear-facing use.

Using the Easy-in Buckle
The easy-in buckle is designed for stress-free loading and unloading of your child. To buckle, insert each buckle tongue into the buckle until it clicks. To unbuckle, press the red release button on the buckle.
Operating the UPF50+ Sun Canopy
The car seat is equipped with an XXL UPF50+ sun canopy to provide shade and protection from the sun. To extend the canopy, pull it forward. To retract, push it back. The canopy can be adjusted to various positions.

Linear Side-Impact Protection (LSP)
The integrated Linear Side-Impact Protection system is built into the shell of the car seat to effectively reduce collision forces in a side-impact crash. Ensure the LSP system is properly deployed if your model requires manual activation (refer to the full manual for specific instructions).
In-Shell Air Ventilation
The car seat features in-shell air ventilation to promote natural airflow, helping to keep your child comfortable and cool during travel.

Maintenance and Care
Regular cleaning and maintenance will ensure the longevity and safety of your car seat.
- Fabric Cleaning: The car seat fabric is made of polyester. Refer to the care label on the fabric for specific washing instructions. Typically, fabrics can be machine washed on a delicate cycle with cold water and mild detergent. Do not use bleach. Air dry only.
- Harness System: Wipe the harness straps with a damp cloth. Do not machine wash or submerge the harness straps, as this can weaken the webbing.
- Plastic and Metal Parts: Clean plastic and metal parts with a mild soap and water solution. Avoid abrasive cleaners.
- Storage: When not in use, store the car seat in a cool, dry place away from direct sunlight.
