Occupant safet
y 39In 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. It can also reduce
the forces to which occupants are exposed
during an accident.
The SRS consists of:
R 1 warning lamp
R belt tensioner s
R belt force limiters
R Airbag s
11 warning lam p 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 instrumen t
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 anddepending on the vehicle's rate of longitudi-
nal deceleration in a collision, in the firs
t
stage the airbag control unit pre-emptively
triggers the belt tensioners.
i The belt tensioners can only be triggered
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 .
Vehicles fitted with adaptive, dual-stage front
airbags: when the first deployment threshold
is reached, the front airbag is filled with
enough gas to reduce the risk of injuries. The
front airbag is only fully inflated if a second
threshold is reached within a few millisec-
onds 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

ess is pre-emptive in nature as the airbag
must be deployed during – and not at the end
of – the collision
.
i Airbags are not deployed in all types of
accidents. 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, each
individual system depends on the type of
accident determined by the control system
in the first stages of the collision (head-on
collision, side impact, rear-end collision
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 deformed significantly ,
e. g. on the bonnet or the wing, without an
airbag being deployed. This happens if only
parts which are relatively easily deformed are
affected and the necessary deceleration does
not occur. Conversely, airbags may be
deployed even though the vehicle suffers only
minor deformations. This is the case if, for
example, very rigid vehicle parts such as lon-
gitudinal body members are affected and suf-
ficient deceleration occurs as a result.
Belt tensioners, belt force limiter s The seat belts are fitted 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 seat
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 belt force limiters are synchronised with
the front airbags, which spread the forces
exerted by the belt force limiters on the occu-
pant 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 1 warning lamp lights up after th e
ignition is switched on and goes out onc e
the engine is running)( Ypage 39)
R for each three-point seat belt in the front of
the vehicle when the belt tongue is
engaged in the buckle
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
during the initial stages of the collision Safety

Driving safety sys
tems 51G
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. 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 scope of the laws of phys-
ics. ESP ®
assists the driver when pulling away
on wet or slippery roads. ES P®
can also sta-
bilise the vehicle 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.
ESP ®
cannot reduce the risk of an accident
if you drive too fast. ESP ®
cannot overrid e
the laws of physics .
! The ignition must be switched off (key in
position 0or Iin the ignition lock) if:
R the vehicle is being towed with the front
or rear axle raised
R you are having the handbrake checke d
on the brake dynamometer
Application of the brakes by ESP ®
could
otherwise destroy the brake system on the
front or rear axle.
i Only use wheels with the recommended
tyre sizes. Only then will ESP ®
function
properly . To deactivate/activate ES
P® 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 situations
described above no longer apply. 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 Engine torque is not limited and the drive
wheels are able to spin. The spinning
wheels produce a cutting effect for better
traction.
R traction control is still activated .
R ESP ®
still provides support when you
brake. Safety
