Starting the engine
The engine starts automatically under the fol‐
lowing conditions:
▷Manual transmission:
The clutch pedal is pressed.▷Automatic transmission:
By releasing the brake pedal.
When Automatic Hold is activated: press the
accelerator.
After the engine starts, accelerate as usual.
Safety mode
After the engine switches off automatically, it
will not start again automatically if any one of the
following conditions are met.
▷The driver's safety belt is unbuckled and the
driver's door is open.▷The hood was unlocked.
Some indicator lamps light up for varying
lengths of time.
The engine can only be started via the Start/
Stop button.
Note
Even if driving away was not intended, the de‐
activated engine starts up automatically in the
following situations:▷Excessive warming of the passenger com‐
partment when the cooling function is
switched on.▷The steering wheel is turned.▷Automatic transmission: the transmission
position is changed from D to N, R, or M/S.▷Automatic transmission: the transmission
position is changed from P to N, D, R, or M/
S.▷The vehicle begins rolling.▷Fogging of the windows when the automatic
climate control is switched on.▷The vehicle battery charge is very low.▷Excessive cooling of the passenger com‐
partment when the heating is switched on.▷Low brake vacuum pressure; this can occur,
for example, if the brake pedal is depressed
a number of times in succession.
Preventing an automatic engine stop
with automatic transmission
The concept
To make it possible to drive away very quickly,
such as at an intersection, the automatic engine
stop can be actively prevented.
Preventing an engine stop using the
brake pedal
The engine stop can be actively prevented
within one second after the vehicle comes to a
standstill.
▷Immediately after the vehicle comes to a
standstill, briefly press the brake pedal
forcefully.Seite 65DrivingControls65

Subject to the following requirements, the park‐
ing brake is automatically released by operation
of the accelerator pedal:▷Engine on.▷Drive position engaged.▷Driver buckled in and doors closed.Inadvertent operation of the accelerator
pedal
Make sure that the accelerator pedal is not op‐
erated unintentionally; otherwise, the vehicle is
set in motion and there is a risk of an accident. ◀
Automatic Hold
The concept
This system assists the driver by automatically
setting and releasing the brake, such as when
moving in stop-and-go traffic.
The vehicle is automatically held in place when
it is stationary.
On inclines, the system prevents the vehicle
from rolling backward when driving away.
For your safety
Under the following conditions, Automatic Hold
is automatically deactivated and the parking
brake is set:
▷The engine is switched off.▷A door is opened and driver's safety belt is
unbuckled while the vehicle is stationary.▷The moving vehicle is brought to a standstill
using the parking brake.
The indicator lamp switches from green
to red and the letters AUTO H go out.
