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 switched
off temporarily when you start the engine. If
the engine does not start immediately, the starting
procedure stops automatically after a short
time. If this is the case, repeat the starting procedure
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 steering
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 minutes
or if you lock the vehicle from the outside.
WARNING
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.
- 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
- Brief noises are normal when starting and
parking the vehicle and are no cause for
concern.
- For up to 10 minutes after stopping the engine,
the radiator fan may turn on again automatically
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.
