Power saving mode
This mode deactivates electrical
consumers to avoid excessive
discharging of the vehicle battery.
These consumers, such as the
Infotainment system, windscreen
wipers, low beam headlights,
courtesy light, etc. can be used for a
total maximum time of about
40 minutes after ignition is switched
off.
Changing into power saving
mode
When power saving mode is
activated, a message appears in the Driver Information Centre indicating
Power saving mode .
An active telephone call using the
hands-free option will be maintained
