Never leave children or people requiring assistance alone in the vehicle. They could become trapped
in the vehicle in an emergency and may not be able to get themselves to safety. For example, locked
vehicles may be subjected to very high or very low temperatures depending on the season. This can
cause serious injuries and illness or fatalities, especially in the case of small children.
Never switch off the ignition while the vehicle is in motion. The steering column lock or steering lock
mechanism may be activated and you will no longer be able to steer the vehicle.

NOTICE
Every electric vehicle key contains electronic components. Protect the key from damage, moisture
and excessive vibration.

Depending on the equipment level, the background lighting provides indirect light in various areas of
the vehicle interior.
The front footwell may also be illuminated.
The brightness of the background lighting can be adjusted in the Infotainment system in the Vehicle
settings menu ⇒ Infotainment system controls and displays .

The lights go out when the vehicle is locked or after a delay of a few minutes when the vehicle key is
removed from the ignition lock. This prevents the 12-volt vehicle battery from discharging.

Some settings can be stored in the user accounts of the personalisation function and therefore
change automatically when the user account changes ⇒ Personalisation .
