By releasing the brake pedal.
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.

Protective action
Airbags are not triggered in every impact situa‐
tion, e.g., in less severe accidents or rear-end
collisions.
Information on how to ensure the optimal
protective effect of the airbags▷Keep at a distance from the airbags.▷Always grasp the steering wheel on the
steering wheel rim, holding your hands at
the 3 o'clock and 9 o'clock positions, to keep
the danger of injury to your hands or arms as
low as possible if the airbag is triggered.▷There should be no people, animals, or ob‐
jects between an airbag and a person.▷Do not use the cover of the front airbag on
the front passenger side as a storage area.▷Keep the dashboard and window on the
front passenger side clear, i.e., do not cover
with adhesive labels or coverings, and do not
attach holders such as for navigation instru‐
ments and mobile phones.▷Make sure that the front passenger is sitting
correctly, i.e., keeps his or her feet and legs
in the footwell; otherwise, leg injuries can
occur if the front airbag is triggered.▷Do not place slip covers, seat cushions or
other objects on the front passenger seat
that are not approved specifically for seats
with integrated side airbags.▷Do not hang pieces of clothing, such as jack‐
ets, over the backrests.▷Make sure that occupants keep their heads
away from the side airbag and do not rest
against the head airbag; otherwise, injuries
can occur if the airbags are triggered.▷Do not remove the airbag restraint system.▷Do not remove the steering wheel.▷Do not apply adhesive materials to the air‐
bag cover panels, cover them or modify
them in any way.▷Never modify either the individual compo‐
nents or the wiring in the airbag system. This
also applies to steering wheel covers, the
dashboard, the seats, the roof pillars and the
sides of the headliner.◀
Even when all instructions are followed closely,
injury from contact with the airbags cannot be
ruled out in certain situations.
The ignition and inflation noise may lead to
short-term and, in most cases, temporary hear‐
ing impairment in sensitive individuals.
In the case of a malfunction, deactivation
and after triggering of the airbags
Do not touch the individual components imme‐
diately after the system has been triggered; oth‐
erwise, there is the danger of burns.
Only have the airbags checked, repaired or dis‐
mantled and the airbag generator scrapped by
your service center or a workshop that has the
necessary authorization for handling explosives.
Non-professional attempts to service the sys‐
tem could lead to failure in an emergency or un‐
desired triggering of the airbag, either of which
could result in injury.◀
Warnings and information on the airbags are
also found on the sun visors.
Functional readiness of the airbag
system
When the ignition is switch on, the warn‐
ing lamp in the instrument cluster lights
up briefly and thereby indicates the op‐
erational readiness of the entire airbag system
and the belt tensioner.
Airbag system malfunctioning
▷Warning lamp does not come on when the
ignition is turned on.▷The warning lamp lights up continuously.Seite 92ControlsSafety92

ahead or stopped in front of you can also be de‐
tected within the system's range.
Personal responsibility
The system cannot serve as a substitute
for the driver's personal judgment of the traffic
situation. The system may not always detect
critical situations reliably and in a timely manner.
Adapt speed to traffic situation and drive alertly;
otherwise, a risk to safety may result.◀
Function
After the safety belt is buckled, the front belts
are automatically tightened once after the vehi‐
cle is driven is away.
In critical driving situations, the following indi‐
vidual functions become active:▷The front belts are automatically tightened.▷Automatic closing of the windows.▷Automatic closing of the glass sunroof.
After a critical driving situation without an acci‐
dent, the front belts are loosened again. All other
systems can be restored to the desired setting.
If the belt tension does not loosen automatically,
stop the vehicle and unbuckle the belt using the
red button in the buckle. Fasten the belt before
continuing on your trip.
PostCrash
In the event of an accident, the system can bring
the car to a halt automatically without interven‐
tion by the driver in certain situations. This can
reduce the risk of a further collision.
Depressing the brake pedal can cause the vehi‐
cle to brake harder. This interrupts automatic
braking. Depressing the accelerator pedal also
interrupts automatic braking.
After coming to a halt, the brake is released au‐
tomatically. Secure the vehicle against rolling.
