Airbag deployment only provides increased
protection if the seat belt is worn correctly.
The seat belt helps, firstly, to keep the vehicle
occupant in the best position in relation to the
airbag. Secondly, in a head-on collision, for
example, the seat belt restricts movement of the vehicle occupant towards the point of
impact. SRS (Supplemental Restraint System)
Introduction Supplemental Restraint System (SRS) with:
R the 6 SRS warning lamp
R airbags
R airbag control unit (with crash sensors)
R belt tensioners for the front seat belts and
the outer seat belts in the rear
R seat belt force limiters for the front seat
belts and the outer seat belts in the rear
SRS reduces the risk of vehicle occupants
coming into contact with parts of the vehi-
cle's interior in the event of an accident. It can
also reduce the forces to which vehicle occu-
pants are subjected during an accident.
SRS warning lamp G
WARNING
If SRS is malfunctioning, restraint system
components may be triggered unintentionally
or might not be triggered at all in the event of
an accident with a high rate of vehicle decel-
eration. There is an increased risk of injury,
possibly even fatal.
Have SRS checked and repaired immediately
at a qualified specialist workshop.
SRS functions are checked regularly when
you switch on the ignition and when the
engine is running. Therefore, malfunctions
can be detected in good time.
The 6 SRS 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.
The SRS components are in operational read-
iness when the 6SRS warning lamp goes
out while the engine is running.
A malfunction has occurred if:
R the 6 SRS warning lamp does not light
up when the ignition is switched on
R the engine is running and the 6SRS
warning lamp does not go out after a few
seconds
R the engine is running and the 6SRS
warning lamp lights up again
Triggering of belt tensioners and air-
bags During the first stage of a collision, the airbag
control unit evaluates important physical
data relating to vehicle deceleration or accel-
eration, such as:
R duration
R direction
R magnitude
Based on the evaluation of this data, the air-
bag control unit pre-emptively triggers the
belt tensioners in the first stage.
If there is an even higher rate of vehicle decel- eration or acceleration in a longitudinal direc-tion, the front airbags are also deployed.
Your vehicle has adaptive, two-stage front air-
bags. The airbag control unit evaluates vehi-
cle deceleration or acceleration in the event
of a collision. In the first deployment stage,
the front airbag is filled with enough propel-
lant gas to reduce the risk of injuries. The
front airbag is fully deployed if a second
deployment threshold is reached within a few milliseconds.
The belt tensioner and airbag triggering
thresholds are variable and are adapted to the
detected rate of deceleration or acceleration of the vehicle. This process is pre-emptive in
nature. The triggering process must take
place in good time at the start of the collision. Occupant safety
41Safety Z

OFF indicator lamp must be continuously
lit.
If the front-passenger seat of your vehicle
does not have automatic child seat recog-
nition, or your rearward-facing child
restraint system does not have a trans-
ponder for automatic child seat recogni-
tion, children must be secured in a child
restraint system on a suitable seat in the
rear. If you secure a forward-facing child
restraint system to the front-passenger
seat, you must move the front-passenger
seat as far back as possible.
R make sure there are no heavy or sharp-
edged objects in the pockets of clothing.
R do not lean forwards, e.g. over the cover of
the driver's/front-passenger front airbag,
particularly when the vehicle is in motion.
R do not put your feet on the dashboard.
R only hold the steering wheel on the outside.
This allows the airbag to be fully deployed.
You could be injured if the airbag is
deployed and you are holding the inside of
the steering wheel.
R do not lean on the doors from inside the
vehicle.
R make sure that there are no people, ani-
mals or objects between the vehicle occu-
pants and the area where the airbags are
deployed.
R do not place any objects between the seat
backrest and the door.
R do not hang any hard objects, e.g. coat
hangers, on the grab handles or coat hooks.
R do not attach accessories, e.g. cup holders,
to the doors.
It is not possible to rule out a risk of injury
being caused by an airbag, due to the high
speed at which the airbag must be deployed. G
WARNING
If you modify the airbag covers or affix
objects, e.g. stickers to them, the airbags may
no longer function as intended. There is an
increased risk of injury. Never modify the airbag covers and do not
affix any objects to them.
G
WARNING
After the driver's airbag has been deployed,
the airbag parts are hot. There is a risk of
injury.
Do not touch the airbag parts. Have deployed airbags replaced immediately at a qualified
specialist workshop.
Airbag deployment slows down and restricts
the movement of the vehicle occupants.
If the airbags are deployed, you will hear a
bang and a small amount of powder may also
be released. Only in rare cases will the bang
affect your hearing. The powder that is
released generally does not constitute a
health hazard and does not indicate that there is a fire in the vehicle. The powder may causeshort-term breathing difficulties to persons
suffering from asthma or other pulmonary
conditions. In order to prevent potential
breathing difficulties, you should leave the
vehicle as soon as it is safe to do so. You can
also open the window to allow fresh air to
enter the vehicle interior. The 6SRS warn-
ing lamp lights up.
The airbag installation locations are identified
by the AIRBAG symbol.
i After an airbag has been deployed, have
the vehicle towed to the nearest qualified
specialist workshop, even if your vehicle
can still be driven.
Front airbags !
Do not place heavy objects on the front-
passenger seat. This could cause the sys-
tem to identify the seat as being occupied.
In the event of an accident, the restraint
systems on the front-passenger side may
be triggered and have to be replaced. Occupant safety
43Safety Z

You can also cancel the rear seat belt status
indicator immediately (Y page 234).
i The status indicator for the rear-compart-
ment seat belts is only available for certain
countries.
Belt tensioners, belt force limiters G
WARNING
Pyrotechnic seat belt tensioners that have
been deployed are no longer operational and
are unable to perform their intended protec-
tive function. This poses an increased risk of
injury or even fatal injury.
Therefore, have pyrotechnic belt tensioners
which have been triggered immediately
replaced at a qualified specialist workshop.
! If the front-passenger seat is not occu-
pied, do not engage the seat belt tongue in
the buckle on the front-passenger seat.
Otherwise, the belt tensioner could be trig- gered in the event of an accident.
i Vehicles with PRE-SAFE ®
: an electric
motor is used by PRE-SAFE ®
to trigger the
tightening of the seat belt in hazardous sit- uations. This procedure is reversible.
The front seat belts and the outer seat belts in
the rear are equipped with belt tensioners
and belt force limiters.
The belt tensioners tighten the seat belts in an
accident, pulling them close against the body.
Belt tensioners do not correct incorrect seat
positions or incorrectly fastened seat belts.
Belt tensioners do not pull vehicle occupants
back towards the backrest.
The belt tensioners can only be activated
when:
R the ignition is switched on
R the restraint systems are operational; see
"SRS warning lamp 6" (Ypage 41)
R the belt tongue has engaged in the belt
buckle of the respective front seat The belt tensioners on the outside seats in the
rear compartment are triggered independ-
ently of the lock status of the seat belts.
The belt tensioners are triggered depending
on the accident type and severity:
R in the event of a head-on or rear-end colli-
sion if the vehicle decelerates or acceler-
ates rapidly in a longitudinal direction dur-
ing the initial stages of the impact
R in the event of a side impact if the vehicle
decelerates or accelerates rapidly in a lat-
eral direction on the side opposite to the
impact
R in certain situations where the vehicle over-
turns and the system determines that it canprovide additional protection
If the airbags are deployed, you will hear a
bang, and a small amount of powder may also be released. Only in rare cases will the bang
affect your hearing. The powder that is
released generally does not constitute a
health hazard and does not indicate that thereis a fire in the vehicle. The powder may causeshort-term breathing difficulties to persons
suffering from asthma or other pulmonary
conditions. In order to prevent potential
breathing difficulties, you should leave the
vehicle as soon as it is safe to do so. You can
also open the window to allow fresh air to
enter the vehicle interior. The 6SRS warn-
ing lamp lights up.
If the seat belt is also fitted with a belt force
limiter and this is triggered, the force exerted by the seat belt on the vehicle occupant is
reduced.
The belt force limiters on the front seats are
synchronised with the front airbags, which
take on a part of the deceleration force. This
results in the load being distributed over a
greater area. 50
