cult for emergency workers to enter the ve-
hicle, which puts lives at risk.

rage door. In some situations, the function
may be limited or temporarily unavailable.
This may happen if:
— You are standing too close to the bumper or
too far away from it

opened immediately beforehand
— You park close to a hedge and the branches
move back and forth under the vehicle for a
long period of time
— You clean your vehicle, for example with a
pressure washer or in a car wash

assist the driver. They do not relieve the
driver of responsibility to check the head-
lights and to turn them on manually based
on the current light and visibility conditions.
For example, fog cannot be detected by the
light sensors. So always switch on the low
beams ZO under these weather conditions

and when driving in the dark.

for a while, the parking light may switch off
automatically. Avoid using the parking
lights for several hours.

hicle when braking or in the event of an acci-
dent.
— Incorrect usage can lead to serious injuries
or burns. To reduce the risk of injuries, never
leave children unattended in the vehicle
with the vehicle key.

@) Note

nected devices.
—To reduce the risk of damage to the vehicle
electrical system, never attempt to charge
the vehicle battery by connecting accesso-
ries that provide power to the power sour-
ces.

Starting the vehicle
Dye Tod f ola (ela)



Fig. 85 Center console: starting the engine
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 with
the selector lever in the P position and open the
driver's door. The steering lock helps prevent ve-
hicle theft.
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.

ZA 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.
— Always select the “P” selector lever position
when parking the vehicle; otherwise, the ve-
hicle could roll away.
o Note
— Avoid high engine speed, full throttle, and
heavy engine load if the engine has not


93

Driving

reached operating temperature yet. You
could damage the engine.
— 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 damag-
ing the engine. For this reason, let the en-
gine run at idle for approximately two mi-
nutes before shutting it off.
@ Tips
— Brief noises are normal when starting and
stopping the vehicle and are no cause for
concern.
— For up to 10 minutes after stopping the en-
gine, the radiator fan may turn on again au-
tomatically or it may continue to run, even if
the ignition is switched off.
— It may not be possible to start the vehicle in
extremely low temperatures.
— Power will be fully available once the engine
is at operating temperature.
