Technical Data
In certain accident si
tuations, the front, side and he
ad airbag are simultaneously
deployed. The airbags inflate in fractions of a second
and at a high speed in order to be able
to offer that additional protection in th
e event of an accident. A grey white, non
harmful gas is released when airbag is inflated. This is perfectly normal and is not an indication of a fire in the vehicle.Important safety information on the head airbag Correct use of the airbag system considerably reduces the risk of injury!
WARNING
•
It is essential to always switch off
⇒page 181, “Deactivating an airbag”
the front passenger airbag when attach
ing a child safety seat on the front
passenger seat where the child is seated
with its back facing in direction of
travel (in some countries also when the ch
ild is facing the direction of travel).
If this is not done, there is a risk of
the child suffering severe or even fatal
injuries if the front passenger airbag
is deployed. In certain countries
national legal provisions also requir
e that the side or head passenger
airbags be deactivated. When transporting a child on the front passenger seat, please comply with the appropri
ate national regulations regarding the
use of child safety seats.•
There must not be any objects in the deployment area of the head
airbags which might prevent the ai
rbags from inflating properly.
•
Only hang light items of clothing on the clothes hooks to the vehicle.
Never leave any heavy or sharp-edged objects in the pockets of the items of clothing. In addition, it is not permitted to use clothes hangers for hanging up items of clothing.•
The airbag control unit
operates together with the sensors, which are
attached in the front doors. For this reason no adjustments must be carried out at the doors as well as at the door panels (for example additional instal- lation of loudspeakers). Resulting dama
ges can have a negative affect on the
operation of the airbag system. All work
on the front doors and their panels
must only be carried ou
t by a specialist garage.
•
There must not be any other persons (e.g. children) or animals between
the car occupant and the deployment ar
ea of the head airbag. In addition,
none of the occupants should lean their head out of the window when driving, or extend their arms and hands out of the window.•
The sun visors must not be swivelled to the side windows into the
deployment area of the head airbags if any objects, such as ball-point pens etc. are attached to them. This might resu
lt in injuries to the occupants if the
head airbag is deployed.•
Installing impermissible accessories in
the area of the head airbags may
considerably impair the protection offered by the head airbag in the event of it being deployed. When the deployed he
ad airbag is inflated, parts of the
accessories fitted may in certain circum
stances be thrown into the interior
of the car and cause injuries to the occupants
⇒page 244, “Accessories,
changes and replacement of parts”.•
Any work on the head airbag system
including installing and removing
system components because of other repair work (e.g. removing headliner) must only be carried out by a specialist garage.Deactivating an airbagDeactivating airbags If any airbags have been deactivated, switch them on again as soon as possible so that they are able to
again provide their proper protec-
tion.There is the technical means installed within your vehicle to switch off the front, side* or head* airbag (take out of commission). This is why you should have the deacti
vation of the airbags carried out by a
specialist garage. On vehicles equipped with the switch for de
activation of the airbags, you can deac-
tivate the front and side passenger
airbag by means
of this switch

Deactivation of airbags is envisaged only for particular instances, such as if:•
you must
in exceptional cases
use a child seat on the front passenger seat
where the child has its back to the directio
n of travel of the vehicle (in some coun-
tries this must be in the direction of trav
el due to other legal regulations applying)
⇒ page 184, “Important safety information regarding the use of child safety seats”,•
you are not able to maintain the distance of at least 25 cm between middle of
steering wheel and chest, despite the
driver seat being correctly adjusted,
•
special attachments are required in the area of the steering wheel because of a
physical disability,•
you have installed other seats (e.g. orthopaedic seats without side airbags).
Monitoring the airbag system The functionality of the airbag system is also monitored electronically, when one airbag has been switched off If the airbag was switched off using diagnostic equipment:•

Driving TipsIntelligent TechnologyElectronic stability programme (ESP)*GeneralGeneral The ESP aids you maintain control of your vehicle in situations in borderline driving situations such as when negotiating a curve too fast. The risk of skidding is reduced and your vehicle thus offers greater driving stability depending on the conditions of the road surface. This occurs at all speeds. The following systems are integrated into the electronic stability programme:•
Electronic Differential Lock (EDL),
•
Traction control system (TCS),
•
Active driver-steering recommendation (DSR),
•
Antilock brake system (ABS),
•
Brake Assist,
•
Uphill-Start off-Assist.
Operating principle The ESP switches on automatically when the engine is started and then conducts a self-test. The ESP control unit processes data from the individual systems. It also processes additional measurement data which are supplied by highly sensitive sensors: the rotational velocity of the vehi
cle about its vertical axis, the lateral accel-
eration of the vehicle, the brakin
g pressure and the steering angle.
The direction which the driver wishes to ta
ke is determined based on the steering
angle and the speed of the vehicle and is constantly compared with the actual behaviour of the vehicle. If differences exis
t, such as the vehicle beginning to skid,
the ESP will automatically brake the appropriate wheel. The car is stabilised again by the forces which take effect when the wheel is braked. Intervention into the brake system takes place primarily on the outer front wheel of a vehicle which tends to oversteer (tendency for the rear of the vehicle to break away) while occurs this is on the inner re
ar wheel of a vehicle which tends to under-
steer (tendency to shift out of the curve). This braking control cycle is accompanied by noises. The ESP operates in combination with the ABS
⇒page 197, “Antilock brake system
(ABS)”. If there is a fault in the ABS system, the ESP also does not operate. The ESP warning light lights up in the instru
ment cluster when there is a fault on the
ESP
 ⇒page 37.
Switching off You can switch the ESP off and on again
as you wish, by pressing the button
⇒ fig. 196
. The ESP warning light lights up in th
e instrument cluster when the ESP is
switched off
 ⇒page 37.
The ESP should normally always be switched
on. It may be good practice in certain
exceptional cases, such as when you wish
to have wheel slip, to switch off the
system. Examples:

•
when driving with snow chains
•
when driving in deep snow or on a loose surface
•
when it is necessary to rock a vehicle when it has become stuck.
then you should switch on the ESP again.
WARNING
It is also not possible for the ESP to overcome the physical limits of the vehicle. Even if a vehicle fitted with ESP you should still always adapt your style of driving to the condition of the
road surface and the traffic situation.
This particularly applies when driving on slippery and wet roads. The increased safety offered must not tempt you to take greater risks than other- wise - risk of an accident!
Note
•
All four wheels must be fitted with the same tyres in order to achieve problem-
free operation of the ESP. Differing rolling
circumferences of the tyres can lead to an
undesirable reduction in the engine output.•
Changes to vehicle (e.g. on engine, on the brakes, on chassis or other assign-
ment of tyres and wheels) can influence the function of the ESP
⇒page 244,
“Accessories, changes and replacement of parts”.Electronic Differential Lock (EDL)* The electronic differential lock pr
events an individual wheel from
slipping.Models fitted with ESP are equipped with electronic differential lock (EDL). General The EDL makes it much easier, and sometimes at all possible, to start off, accelerate and climb a steep hill when the conditio
ns of the road surface are unfavourable.
Operating principle The EDL is activated automatically, that is
without any action on the part of the
driver. It monitors the speeds of the driven wheels with the aid of the ABS sensors. Should only
one
drive wheel begin spinning on a slippery surface there will be an
appreciable difference in the speed of the driven wheels. The EDL function brakes the slipping wheel and the differential transmits a greater driving force to the other driven wheel. This control proces
s is also accompanied by noises.
Overheating of the brakes The EDL switches off
automatically if unusually severe
stresses exist in order to
avoid excessive heat generation in the
disc brake on the wheel which is being
braked. The vehicle can continue to be driv
en and has the same characteristics as a
vehicle not fitted with EDL. The EDL switches on again
automatically as soon as the brake has cooled down.
WARNING
•
Carefully depress the accelerator when accelerating on uniformly slip-
pery road surfaces, such as ice and sn
ow. The driven wheels might still spin
despite the EDL and affect the stability
of the vehicle - risk of an accident!
•
You should always adapt your style of driving to the condition of road
surface and to the traffic situation even
when your vehicle is fitted with EDL.
The increased safety offered must not tempt you to take greater risks than otherwise - risk of an accident!
Note
•
If the ABS or ESP warning light comes on,
this may also indicate a fault in the
EDL. Please have the vehicle inspected as soon as possible by a specialist garage.•
Changes to vehicle (e.g. on engine, on
the brakes, on chassis or other assign-
ment of tyres and wheels) can in
fluence the function of the EDL

Traction control system (TCS) The traction control system prevents
the driven wheels from spinning
when accelerating.General The TCS makes it much easier, and sometimes at all possible, to start off, accelerate and climb a steep hill when the conditio
ns of the road surface are unfavourable.
Operating principle The TCS switches on automatically when th
e engine is started and then conducts a
self-test. The system monitors the speeds of the driven wheels with the aid of the ABS sensors. If the wheels are spinning, the force transmitted to the road surface is automatically adapted by redu
cing the engine speed. Th
is occurs at all speeds.
The TCS operates in combination with the ABS

Switching off You can switch the TCS off and on again
as you wish by pressing the button

pped with active driver-steering recommendation (DSR).
This function indicates to the driver in critical situations a steering recommendation in order to stabilise the vehicle. The active driver-steering recommendation is acti-vated, for example, on the right and left
vehicle side when
braking sharply on
different road surfaces.

WARNING
Even with this function the vehicle ca
nnot steer itself! The
driver is further-
more responsible for the steering of the vehicle!BrakesWhat has a negative effect on braking efficiency?Wear-and-tear Wear-and-tear to the brake pads is greatly dependent on the operating conditions of the vehicle and your style of driving. Particularly if you drive a great deal in towns and over short distances or if you adopt a
sporty style of driving, it may be neces-
sary to have the thickness of the brake
pads inspected at a specialist garage
between the service inspections. Wet roads or road salt There may be a certain delay before the br
akes take full effect under certain condi-
tions such as when driving through water,
during heavy rain
showers or after the
vehicle has been washed in
an automatic vehicle wash, since the brake discs and
brake pads may be moist or even have a
coating of ice on them in winter. You
should dry the brakes as soon as possib
le by applying and releasing the brakes
several times. There also may be a certain delay before the
full braking efficiency is available when
driving on roads which have been treated wi
th road salt if yo
u have not used the
brakes for some considerable time beforeha
nd. The layer of salt on the brake discs
and brake pads must first be rubb
ed off when you apply the brakes.
Corrosion Corrosion on the brake discs and dirt on th
e bake pads occur if
the vehicle has been
parked for a long period and if you do
not make much use of the braking system.
We recommend cleaning the brake discs by
firmly applying the brakes at a fairly
high speed if you do not make much use of the braking system or if surface corro- sion is present
⇒
.
Faults in the brake surface If you notice that the braking distance
has suddenly become longer and that the
brake pedal can be depressed further, it is
possible that a brake circuit of the dual-
circuit brake system has failed. Drive, in such cases, to the nearest specialist garage without delay in order to have the problem rectified. Drive at a reduced speed while on your way to the dealer and adapt your style of driving to the higher brake pedal pressure required. Low brake fluid level An insufficient level of brake fluid may result in problems in the brake system. The level of the brake fluid is monitored electronically
⇒page 40, “Brake system
”.
WARNING
•
Only apply the brakes for the purpos
e of drying and cleaning the brake
discs if the traffic conditions permit this. Do not place any other road users in jeopardy.•
When retrospectively mounting a front
spoiler, solid wheel hubs etc. one
must ensure that the air supply to the front wheel brakes is not reduced otherwise the braking sy
stem could run too hot.
•
Allow for the fact that new brake pads
do not achieve th
eir full braking
efficiency until approximately 200 kilo
metres. New brake pads must be first
“run in” before they develop their optimal friction force. You can, however, compensate for this slightly reduced
braking force by increasing the pres-
sure on the brake pedal. This guidelin
e also applies to any new brake pads
installed at a future date.
Caution
•
Never allow the brakes to ru
b by applying slig
ht pressure if you do not wish to
brake the vehicle. This causes the brakes to overheat and can also result in a longer braking distance and excessive wear.•
Before negotiating a steep downhill sect
ion, please reduce your speed, shift
down into the next lower gear (manual ge
arbox) or select a lower driving stage
(automatic gearbox). This enables you to make full use of the braking power of the

rated when the engine is running.
WARNING
•
Never switch off the engine before the vehicle is stationary.
•
The brake booster only operates when the engine is running. Greater
physical effort for braking is required
when engine is switched off. Because
if you do not stop as normal, this can cause an accident and severe injuries.Antilock brake system (ABS)ABS prevents the wheels locking when braking.General The ABS contributes significan
tly to enhancing the active
safety of your vehicle.
Compared to a vehicle not fitted with the ABS brake system, you are able to retain optimal steering ability even during a fu
ll brake application on a slippery road
surface because the wheels do not lock up. You must not expect, however, that the br
aking distance will be shorter under all
circumstances as a result of the ABS. Th
e braking distance for example on gravel
and fresh snow, when you should anyway be driving slowly and cautiously, will be longer. Operating principle The brake pressure will be reduced on a wheel which is rotating at a speed which is too low for the speed of the vehicle and tend
ing to lock. This control cycle is notice-
able from a
pulsating movement of the brake pedal
which is accompanied by
noises. This is consciously intended to provide the driver with the information that the wheels are tending to lock (ABS control range). You must always keep the brake pedal depressed to enable the ABS to optima
lly control the brake application in this
braking range. Never interrupt the application of the brakes!
WARNING
•
The ABS can also not overcome the physic
al limits of your vehicle. Please
do not forget this, particularly when driv
ing on icy or wet road surfaces. If the
ABS is operating within the control ra
nge, adapt your speed immediately to
the conditions of the road surface and the traffic situation. The increased safety offered by the ABS must not tempt you to take greater risks than otherwise - risk of an accident!•
The normal braking system is still fully
functional if there is an ABS fault.
Visit a specialist garage as quickly as po
ssible and adjust yo
ur style of driving
to take account of the ABS fault in the meantime since you will not know how great the damage is.
Note
