Notes
When the ignition is switched off, selector
lever position P will be automatically engaged,
if selector lever position D or R is engaged.
With the vehicle stationary and the engine shut
down, the ignition is switched off automatically
under the following circumstances:▷When locking, even with the low-beam
headlights switched on.▷Shortly before the battery is discharged so
that an engine start remains possible.▷When opening or closing the driver's door,
if the driver's belt is unfastened and the
low-beam headlights are switched off.▷When the driver's belt is unfastened, if the
driver's door is opened and the low-beam
headlights switched off.
After about 15 minutes without further opera‐
tion, low-beam headlights are changed over to
side lights.
Radio ready state
Activate radio ready state: when the engine is
running, press the start/stop button.
Individual electrical systems remain opera‐
tional.
The radio ready sate is automatically switched
off in the following situations:

▷After approximately eight minutes.▷When locking via the central locking sys‐
tem.▷Shortly before the battery is discharged so
that an engine start remains possible.
Radio readiness remains active when ignition
is switched off automatically, such as for
following reasons:
▷Opening or closing driver's door.▷Unfastening driver's seat belt.▷When low-beam headlights are automati‐
cally changed to side lights.
If engine is switched off and ignition is
switched on, radio ready state will be automati‐
cally activated when door is opened if light is
switched off or daytime driving lights are
switched on, when corresponding equipment
is fitted.
Engine start Notes DANGER
A blocked exhaust pipe or inadequate
ventilation can allow harmful exhaust fumes to
penetrate the vehicle. The exhaust gas con‐
tains carbon monoxide, which is colourless and
odourless, but highly toxic. In enclosed spaces,
the exhaust fumes can also build up outside
the vehicle. Danger of fatal injury. Keep the ex‐
haust pipe clear and ensure sufficient ventila‐
tion.◀
WARNING
An unsecured vehicle can start moving
and rolling away. Danger of accidents. Before
leaving the vehicle, secure it to prevent rolling
away.
Observe the following to ensure that the vehi‐
cle is secured against rolling away:
▷Engage the parking brake.▷Turn the front wheels into the direction of
the kerb on upward or downward gradi‐
ents.▷Additionally secure the vehicle on upward
or downward gradients, e.g. using a
wedge.◀
ATTENTION
Repeated start attempts or starting sev‐
eral times in quick succession means that fuel
is not combusted, or insufficiently so. The cat‐
alytic converter can overheat. Danger of dam‐
age to property. Avoid starting more than once
in quick succession.◀
