ary.
— The power front seats can also be adjusted
when the ignition is switched off. To reduce
the risk of injury, children should never be
left unattended in the vehicle for this rea-
son.

height. Unsupervised or careless seat adjust-
ment could cause parts of the body to get
pinched, which increases the risk of injury.
— The front seat backrests must not be re-
clined too far back when driving, because
this impairs the effectiveness of the safety
belts and airbag system, which increases the

risk of injury.

Requirement: the key must be in the vehicle.
Starting the engine
> Press and hold the brake pedal.
> Press the [START ENGINE STOP] button. The


engine will start.
Equipment that uses a lot of electricity is switch-
ed off temporarily when you start the engine. If
the engine does not start immediately, the start-
ing procedure stops automatically after a short
time. If this is the case, repeat the starting pro-
cedure after approximately 30 seconds.
Stopping the engine
> Bring the vehicle to a full stop.
> Press the [START ENGINE STOP] button. The


engine will switch off.
Applies to: vehicles with steering lock: The steer-
ing is locked when you turn off the engine and
open the driver's door. The steering lock helps
prevent vehicle theft. “P” must be engaged on
vehicles with an automatic transmission.
Stopping the engine in an emergency
If necessary in an emergency, the engine can also
be stopped while driving using the emergency off
function*.

> Press the [START ENGINE STOP] button twice in
a row or press and hold it one time.

Switching on and off
If you would like to switch the ignition on or off
without starting the engine, follow these steps:

> Press the [START ENGINE STOP] button without
pressing the brake pedal.

Switching the ignition off automatically
To prevent the vehicle battery from draining, the
ignition and possibly the exterior lighting may
switch off automatically.
Requirements:
— The Start/Stop system must have stopped the
engine.
— You must have left the vehicle for longer than
30 seconds.
— The ignition must be switched on.
Among other indicators, the system detects that
you have left the vehicle based on the following
factors:
— The driver's door has been opened.
— The driver's safety belt has been unbuckled.
— The brake pedal is not being pressed.
The ignition will also be switched off after 30 mi-
nutes or if you lock the vehicle from the outside.

Z\ WARNING
—To reduce the risk of asphyxiation, never al-
low the engine to run in confined spaces.
— 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 would then need to use
more force to steer and brake the vehicle.
The fact that you cannot steer and brake as
usual may increase the risk of accidents and
serious injuries.
— Secure the vehicle against rolling before ex-
iting the vehicle > page 96.

CG) Note
— Avoid high engine speed, full throttle, and
heavy engine load if the engine has not
reached operating temperature yet. You
could damage the engine.
