Key positions - functions at different levels

Updated 08/06/2023

To enable the use of a limited number of functions with the engine switched off, the car's electrical system can be set in 3 different levels (key positions) - 0, I and II - with the remote control key. This owner's manual describes these levels throughout using the denomination "key positions".

The following table shows the functions available in each key position/level.

Level	Functions
0	Odometer, clock and temperature gauge are illuminated. Electrically operated seats can be adjusted. The audio system can be used for a limited time - see the Sensus Infotainment supplement.
I	Panorama roof, power windows, 12 V socket in the passenger compartment, navigation, phone, ventilation fan and windscreen wipers can be used.
II	The headlamps come on. Warning/indicator lamps illuminate for 5 seconds. Several other systems are activated. However, electric heating in seat cushions and the rear window can only be activated after starting the engine. This key position consumes a lot of current from the starter battery and should therefore be avoided!

Selecting key position/level

Key position 0 - Unlock the car - This means that the car's electrical system is at level 0.
Key position I - With the remote control key fully inserted into the ignition switch1 - Briefly press START/STOP ENGINE.

Note

To reach level I or II without starting the engine - do not depress the brake/clutch pedal when these key positions are due to be selected.

Key position II - With the remote control key fully inserted into the ignition switch1 - Give a long2 press on START/STOP ENGINE.
Back to key position 0 - To return to key position 0 from position II and I - Briefly press on START/STOP ENGINE.
