Emergency off function*
If it is absolutely necessary, the engine can also
be turned off while driving at speeds starting at
4 mph (7 km/h). To stop the engine, press the
START ENGINE STOP] button twice in a row or


press and hold it one time.

Z\ WARNING
— Never turn off the engine before the vehicle
has come to a complete stop. Switching it
off before the vehicle has stopped may im-
pair the function of the brake booster and
power steering. You may need to use more
force when braking or steering. Because you
cannot brake and steer as you usually would,
this could lead to accidents and serious inju-
ries.
— If you leave the vehicle, switch the ignition
off and take the vehicle key with you. If you
do not do this, the engine could be started
and electrical equipment such as the power
windows could be activated. This can lead to
serious injuries.
— For safety reasons, always park the vehicle
with the selector lever in the P position.
Otherwise, there is the risk that the vehicle
could roll unintentionally.
@) Note
If the engine has been under heavy load for an
extended period of time, heat builds up in the
engine compartment after the engine is
switched off and there is a risk of damaging
the engine. For this reason, let the engine run
at idle for approximately two minutes before
shutting it off.
@) Tips
For up to 10 minutes after stopping the en-
gine, the radiator fan may turn on again auto-
matically or it may continue to run, even if the
ignition is switched off.

General information
Applies to: vehicles with Start/Stop system
Starting and stopping the engine automat-
ically
The system checks if certain conditions are met
before and during the Stop phase, and deter-
mines if the engine stops and how long it re-
mains stopped. For example, if power usage is
high, the engine will not be stopped. Along with
78
other conditions, the following factors influence
the automatic engine start or stop:
— Environmental conditions (slopes, inclines, ele-
vation, temperature)
— Battery (charge status, temperature, power us-
age)
— Engine temperature
— Assist systems
— Driving behavior
Depending on the engine, the indicator light
may appear if the engine is not stopped.

ignition will switch off automatically under the
following conditions:
— If the vehicle has already been driven
— If the Start/Stop system has stopped the en-
gine
— If the driver's door is opened
— If the driver's safety belt is unbuckled
— If the brake pedal is not pressed
— If the vehicle is stationary
