Occupant safety
41deceleration force would normally be high
enough to trigger the systems, or they
could be triggered unintentionally. Never
carry out any modifications on the restraint
systems.
Never tamper with electronic components
and their software.
SRS (Supplemental Restraint System)
The SRS reduces the risk of occupants com-
ing into contact with the vehicle's interior in
the event of an accident. It can also reduce
the forces to which occupants are subjected
during an accident.
The SRS consists of:
R the 1 warning lamp
R belt tensioners
R belt force limiters
R airbags
The 1 1 warning lamp The SRS functions are checked regularly
when you turn on the ignition and when the
engine is running. Malfunctions can therefore
be detected in good time. The
1 warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out no later than a few seconds
after the engine is started. G
Risk of injury
If SRS is malfunctioning, individual systems
may be activated unintentionally or not be
triggered in the event of an accident with
heavy braking.
A malfunction has occurred if the 1
warning lamp:
R does not light up when you switch on the
ignition
R does not go out after the engine has been
running for a few seconds
R lights up again once the engine is running
In this case, have SRS checked immedi-
ately at a qualified specialist workshop.
Triggering of belt tensioners, belt force
limiters and airbags In the event of a collision, the sensor in the
airbag control unit evaluates important phys-
ical data such as duration, direction and force
of the vehicle deceleration or acceleration.
Based on the evaluation of this data, and depending on the vehicle's rate of longitudi-
nal deceleration in a collision, the airbag con-
trol unit pre-emptively triggers the belt
tensioners in the first stage.
i
The front belt tensioners can only be trig-
gered if the belt tongue is correctly
engaged in the seat belt buckle.
The front airbags are only deployed if there is
an even higher rate of vehicle deceleration in
a longitudinal direction.
Your vehicle has adaptive, dual stage front
airbags. When the first activation threshold
has been reached, the front airbag is filled
with enough propellant gas to minimise the
risk of injury. The front airbag is only fully
inflated if a second threshold is reached
within a few milliseconds, due to the control
unit having detected further deceleration.
Criteria for triggering belt tensioners and
airbags
In the first stage of a collision, the airbag con-
trol unit evaluates the duration and direction
of vehicle acceleration or deceleration in
order to determine whether it is necessary to
trigger the belt tensioner and/or airbag.
The belt tensioner and airbag triggering
thresholds are variable and are adapted to the
rate of deceleration of the vehicle. This proc- Safety

Anti-theft syste
ms 63Tow-away protection*
An audible and visual alarm is triggered if your
vehicle's angle of inclination is altered while
tow-away protection is primed. This happens
if the vehicle is jacked up on one side, for
example.
Priming tow-away protection X
Lock the vehicle using the key. On vehicles
with KEYLESS GO*, the locking button on
the door handle/boot lid/tailgate can also
be used.
Tow-away protection is primed after
approximately 30 seconds.
To deactivate tow-away protection When you unlock your vehicle using the key
or KEYLESS GO
*,tow-away protection is
automatically deactivated.
Deactivate tow-away protection manually to
prevent a false alarm if your vehicle:
R is being transported
R is being loaded, e.g. onto a ferry or car
transporter
R is being parked on a movable surface, e.g.
split-level garages 1
To deactivate tow-away protection
2 Indicator lamp
X Remove the key from the ignition lock.
X Press button 1.
Indicator lamp 2lights up briefly.
X Lock the vehicle using the key. On vehicles
with KEYLESS GO*, the locking button on
the door handle/boot lid/tailgate can also
be used.
Tow-away protection remains deactivated
until the vehicle is unlocked and locked
again. Interior motion sensor*
If the interior motion sensor is primed, a vis-
ual and audible alarm is triggered if move-
ment is detected in the vehicle interior while
the vehicle is locked. This occurs, for exam-
ple, if someone breaks the side windows of
your vehicle or reaches into the vehicle's inte-
rior.
Priming the interior motion sensor X
Make sure that:
R
the side windows are closed
R the sliding/tilting sunroof* or panorama
sliding sunroof* is closed
R there are no objects, e.g. mascots, hang-
ing on the rear-view mirror or on the
grasp handles on the roof trim.
This will prevent false alarms.
X Lock the vehicle using the key. On vehicles
with KEYLESS GO*, the locking buttons on
the door handle/boot lid/tailgate can also
be used.
The interior motion sensor is primed after
approximately 30 seconds. Safety
