To save battery power when the engine is off,
switch off the ignition and any unnecessary
electronic systems/power consumers.
The ignition switches off automatically:▷When the vehicle is locked, if the low beams
are switched on.▷Shortly before the battery is discharged
completely, so that the engine can still be
started.▷If the engine is switched off and the ignition
is switched on, the system automatically
switches to the radio ready state when the
door is opened if the lights are switched off

Starting the engine
General information Enclosed areas
Do not let the engine run in enclosed
areas; otherwise, breathing of exhaust fumes
may lead to loss of consciousness and death.
The exhaust gases contain carbon monoxide, an
odorless and colorless but highly toxic gas.◀
