Occupant safet
y 47In particular, work relevant to safety or on
safety-related systems must be carried out
at a qualified specialist workshop. If this
work is not carried out correctly, the oper-
ating safety of your vehicle may be affec -
ted. There is a risk of an accident and injury .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.
The SRS consists of:
R The SRS warning lamp =
R Belt tensioners
R Belt force limiters
R Airbag s
The SRS 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 = warning lamp in the instrumen t
cluster lights up when you switch on the igni -tion and goes out 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 =
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, in the firs
tstage the airbag control unit pre-emptively
triggers the belt tensioners.
The front airbags are only deployed if there is
an even higher rate of vehicle deceleration in
a longitudinal direction.
If your vehicle is fitted with adaptive dual-
stage front airbags, the front airbag is filled
with enough gas to reduce the risk of injuries
at the first deployment threshold. The front
airbag is only fully inflated if a second thresh-
old is reached within a few milliseconds due
to the control unit having detected further
deceleration.
i
The front belt tensioners can only be trig-
gered if the belt tongue is correctly
engaged in the seat belt buckle.
Criteria for triggering belt tensioners and
airbags
In the first stages of a collision, the sensor in
the airbag control unit evaluates physical
data such as duration, direction and rate of
vehicle deceleration or acceleration in order
to determine whether it is necessary to trig-
ger the belt tensioners and/or airbags.
The belt tensioner and airbag triggerin g
thresholds are variable and are adapted to the
rate of deceleration of the vehicle. This proc-
ess is pre-emptive in nature as the airba g Safety

must be deployed during – and not at the end
of – the collision
.
i Airbags are not deployed in all types of
accident. They are controlled by comple x
sensor technology and evaluation logic.
This process is pre-emptive in nature as
airbag deployment must take place during
the impact and must be adapted to provide
calculated, additional protection for the
vehicle occupants. Not all airbags are
deployed in an accident.
The different airbag systems work inde-
pendently of each other. However, the
deployment of each individual system will
depend on the type of accident determined
by the control system in the first stages of
the collision (head-on collision, side impact
and overturn) and the extent of the acci-
dent (in particular, the vehicle's rate of
deceleration or acceleration).
The rate of vehicle deceleration or accelera-
tion and the direction of the force are basi-
cally determined by:
R the distribution of forces during the colli -
sion
R the collision angle R
the deformation characteristics of the vehi-
cle
R the characteristics of the object with which
the vehicle has collided, e.g. the other vehi-
cle
Factors which can only be seen and measured
after the collision has taken place do not play
a decisive role in the deployment of an airbag,
nor do they provide an indication of it.
The vehicle may be considerably deformed
without an airbag being deployed if, for exam-
ple, only relatively easily deformable parts
such as the bonnet or wings have been hit and
the required rate of deceleration has not been
reached. It is also possible that airbags ma y
be deployed even though the vehicle is only
slightly deformed if, for example, very rigid
vehicle parts such as the longitudinal mem-
bers are hit in an accident and the rate of
deceleration is sufficient .
Belt tensioners, belt force limiters The front seat belts and the outer seat belts
in the rear are equipped with belt tensioners.
! Do not engage the seat belt tongue in the
buckle on the front-passenger seat if the
seat is not occupied. Otherwise the belt tensioner could be activated in an emer-
gency.
If the seat belt is also equipped with a belt
force limiter, the force exerted by the sea t
belt on the seat occupant is reduced.
Belt tensioners tighten the seat belts in an
accident, pulling them close against the body.
i Belt tensioners do not correct incorrect
seat positions or incorrectly fastened sea t
belts.
Belt tensioners do not pull occupants back
towards the backrest.
The front belt force limiters are synchronised
with the front airbags, which spread the
forces exerted by the belt force limiters on
the occupant over a greater area.
When the ignition is switched on, the belt ten -
sioner is triggered:
R only if the restraint systems are operational
(the = warning lamp lights up after th e
ignition is switched on and goes out onc e
the engine is running)( Ypage 47)
R for each three-point seat belt in the front of
the vehicle when the belt tongue is
engaged in the buckle

sion if the vehicle decelerates or acceler- Safety

Risk of accident
If ABS is faulty, the wheels could lock when
braking. This limits the steerability of the
vehicle when braking and the braking dis-
tance may increase.
If ABS is deactivated due to a malfunction,
then BAS and ESP are also deactivated. BAS (Brake Assist)
BAS operates in emergency braking situa-
tions. If you depress the brake pedal quickly,
BAS automatically boosts the braking force ,
thus shortening the stopping distance.
X Keep the brake pedal firmly depressed until
the emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated. G
Risk of accident
If BAS has malfunctioned, the braking sys-
tem remains available with full brake boost-
ing effect. However, braking force is not
automatically increased in emergency
braking situations and the stopping dis-
tance may increase. Adaptive brake lamps
i Adaptive brake lamps are only available in
certain countries.
If you brake sharply from a speed of mor e
than 50 km/h or if braking is assisted by BAS,
the brake lamps flash rapidly. In this way,
traffic travelling behind you is warned in an
even more noticeable manner .
If you brake from a speed of more than
70 km/h and bring the vehicle to a halt, the
hazard warning lamps switch on automati-
cally once the vehicle is stationary and the
brake lamps light up constantly if you depres s
the brake pedal again. The hazard warning
lamps switch off automatically if you travel
faster than 10 km/h again. ES
P®
(Electronic Stability Program)
ES P®
monitors driving stability and traction,
i.e. power transmission between the tyres
and the road surface.
If ESP ®
detects that the vehicle is deviatin g
from the direction desired by the driver, one
or more wheels are braked to stabilise the
vehicle. The engine output is also modified, if
necessary, to keep the vehicle on the desired
course within the laws of physics. ESP assists
the driver when pulling away on wet or slip-
pery roads. ESP ®
can also stabilise the vehi-
cle during braking.
When ESP ®
intervenes, the vwarning
lamp flashes in the instrument cluster. G
Risk of accident
If the v warning lamp in the instrumen t
cluster flashes, proceed as follows:
R Do not deactivate ESP ®
under any cir -
cumstances .
R Only depress the accelerator pedal as far
as necessary when pulling away.
R Adapt your driving style to suit the pre -
vailing road and weather conditions.
The vehicle could otherwise go into a skid. Safety

! If the vehicle is to be towed with the front
or rear axle raised, the ignition must be
switched off (key in position 0or 1in the
ignition lock). Application of the brakes by
ESP ®

trailer stabilisin g If your trailer begins to lurch, you can only
stabilise the vehicle/trailer combination by
depressing the brake firmly .
In this situation, ESP ®
assists you and detect s
if the trailer begins to snake. ES P®
slows the
vehicle down by braking and limiting the
engine output until the vehicle/trailer com-
bination has stabilised. Trailer stabilising is active from about
65 km/h. G
Risk of accident
If the road and weather conditions are bad,
trailer stabilising will not be able to prevent
the trailer from lurching or reduce the ris k
of accident. Trailers with a high centre of
gravity can tip over before ESP ®
can detect
this .
Trailer stabilising does not work if ESP ®
is
deactivated or switched off because of a mal-
function .
ETS (Electronic Traction Support) Traction control is part of ES
P®
.
Traction control brakes the drive wheels indi-
vidually if they spin. This enables you to pull
away and accelerate on slippery surfaces, for
example if the road surface is slippery on one
side.
Traction control remains active when you
deactivate ESP ®
. G
Risk of accident
Traction control cannot reduce the risk of
an accident if you drive too fast. Traction
control cannot override the laws of physics .Deactivating/activating ESP
® ESP
®
is activated automatically when the
engine is running.
It may be best to deactivate ES P®
in the fol-
lowing situations:
R when using snow chain s
R in deep sno w
R on sand or gravel G
Risk of accident
Activate ESP ®
as soon as the reason for
deactivation is longer present. ES P®
will
otherwise not be able to stabilise the vehi -
cle if the vehicle starts to skid or a wheel
starts to spin.
If you deactivate ESP ®
:
R ESP ®
no longer improves driving stability.
R The engine's torque is no longer limited and
the drive wheels can spin. The spinning of
the wheels results in a cutting action, which
provides better grip.
R Traction control is still activated.
R ESP ®
still provides support when you
brake. Safety
