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	Sunroof, power windows, 12 V socket in the passenger compartment, navigation, phone, ventilation fan and windscreen wipers can be used. Current consumption loads the starter battery in this key position.
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.
