Function of the head airbags The risk of injury to the head and neck area is reduced in the event of a side collision by fully inflated head airbags.In the case of a
side collision
the head airbag is deployed together with the relevant
side airbag
⇒fig. 144
and the belt tensioner on the side of the car on which the acci-
dent occurs. If the system is deployed, the airbags are filled with propellant gas and extend over the entire area of the side wind
ow including the door pillar
⇒fig. 144
.
The protection offered by the head airbags is
thus available simultaneously both to the
front occupants of the car seated on the side on which the accident occurs, as well as to the rear occupants. Any impact of the head against parts of the interior or objects outside of the car, is cushioned by the in
flated head airbag. The reduction in any
impact to the head and the resultant minimi
zing of any movement
s of the head addi-
tionally reduce the risk of injuries to the neck area. The head airbag also offers addi-tional protection in the case of an offset
impact by covering
the front door pillar.
In certain accident situations, the front, side and head airbag are simultaneously deployed. The airbags inflate in fractions of a second an
d at a high speed in order to be able to
offer that additional protection in the even
t 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 cons
iderably reduces the risk of injury!
WARNING
•
It is essential to always switch off
⇒page 154, “Deactivating an airbag” the
front passenger airbag when attachin
g 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 chil
d is facing the direct
ion of travel). If
this is not done, there is a risk of the ch
ild suffering severe or even fatal injuries
if the front passenger airbag is deploy
ed. In certain countries national legal
provisions also require that the side or
head passenger airbags be deactivated.
When transporting a child on the front passenger seat, please comply with the appropriate 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 airbags 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 installation of loudspeakers). Resulting da
mages 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 out by a specialist garage.•
There must not be any other persons (e
.g. children) or animals between the
car occupant and the deployment area 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 deploy-
ment area of the head airbags if any obje
cts, such as ball-point pens etc. are
attached to them. This might result 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

Driving TipsIntelligent TechnologyElectronic stability programme (ESP)*GeneralGeneral The ESP aids you in maintaining control of
your vehicle in situations in which the
vehicle is driving at its dynamic limits, such as
entering a curve fast. The risk of skidding
is reduced and your vehicle thus offers greater driving stability depending on the conditions of the road surface. The system operates 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.
The ESP system cannot be switched off, the
TCS system can only be switched off by
pressing the button
⇒fig. 154
, then the ESP warning light flashes slowly
.
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 proc- esses additional measurement data which are supplied by highly sensitive sensors: the rotational velocity of the vehicle about its ve
rtical axis, the lateral acceleration of the
vehicle, the braking pressure and the steering angle. The direction which the driver wishes to take is determined based on the steering angle and the speed of the vehicle and is co
nstantly compared with the actual behav-
iour of the vehicle. If
differences exist, such as the vehi
cle beginning to skid, the ESP will
automatically brake the appropriate wheel. The car is stabilised again by the forces wh
ich 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 rear wh
eel of a vehicle whic
h tends to understeer
(tendency to shift out of the curve). This braking control cycle is accompanied by noises. During an intervention of the system, the warning light
 flashes quickly in the instru-
ment cluster
⇒page 35.
The ESP operates in combination with the ABS
⇒page 167, “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 inst
rument cluster when there is a fault on the
ESP
 ⇒page 35.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 surfac
e and the traffic situation. This partic-
ularly applies when driving on slippery
and wet roads. The increased safety

offered must not tempt you to take greater risks than otherwise - risk of an acci- dent!
Note
•
All four wheels must be fitted with the same tyres in order to achieve problem-free
operation of the ESP. Differing rolling circum
ferences of the tyres can lead to an unde-
sirable reduction in the engine output.•
Changes to vehicle (e.g. on engine, on th
e brakes, on chassis or another combina-
tion of tyres and wheels) can influence the function of the ESP
⇒page 221, “Accesso-
ries, changes and replacement of parts”.Electronic Differential Lock (EDL)* The electronic differential lock prev
ents an individual wheel from slip-
ping.Models fitted with ESP ar
e 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 conditions of the road surface are unfavourable. Operating principle The EDL is activated automaticall
y, 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 greate
r driving force to the other driven wheel.
This control process is also accompanied by noises. Overheating of the brakes The EDL switches off automatica
lly 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 driven 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.
EDL Off-road* After switching on the Off-road mode
⇒page 170, EDL Off-road is activated.
EDL Off-road is matched in such a way that it assists the traction of the vehicle when driving on an unfirm ground. EDL is activated earlier in the Off-road mode than in the normal mode. The brake pres- sure builts up more quickly on the slipping
wheel, on one axle, as well as diagonally.
WARNING
•
Carefully depress the accelerator when
accelerating on uniformly slippery
road surfaces, such as ice and snow. Th
e 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 another combina-
tion of tyres and wheels) can influence the function of the EDL

ries, changes and replacement of parts”.

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 th
e conditions 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 auto- matically adapted by reducing the engine speed. The system operates at all speeds. The TCS operates in combination with the ABS
⇒page 167, “Antilock brake system
(ABS)”. The TCS will not function if a fault exists in the ABS system. The TCS warning light lights up in the instru
ment cluster when there is a fault on the
TCS
 ⇒page 34.
During an intervention of the system, the TCS warning light
 flashes quickly in the
instrument cluster
⇒page 34.
Switching off You can switch the TCS off and on again as yo
u wish. On vehicles fitted with ABS, you
can switch off the TCS by pressing the button
⇒fig. 155
, on vehicles fi
tted with ESP*,
you can switch off the TCS wi
th the aid of the button
⇒page 163, fig. 154
. The TCS
warning light
 flashes slowly in the instrument cluster if the system is switched off
⇒ page 34. The TCS 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 TCS again. TCS Off-road* After switching on the Off-road mode
⇒page 170, TCS Off-road is activated.
TCS Off-road provides a more effective a
cceleration of the vehicle on an unfirm
ground, as it allows higher traction be
tween the slipping wheels and the ground.
The system operates when starting off or at low speeds.
WARNING
You should always adjust your style of driving to the conditions of the road surface and the traffic situation. The increased safety offered must not tempt you to take greater risks than otherwise - risk of an accident!

Tyre inflation pressu
re-control system*
The tyre inflation pressure-control system compares with the aid of the ABS sensors the speed and also the rolling circumference of the individual wheels. If the rolling circumference of a wheel is changed, the warning light
 lights up in the instrument
cluster
⇒page 35 and an audible signal sounds.
The rolling circumference of the tyre
can change if:•
the tyre inflation pressure is too low,
•
the structure of the tyre is damaged,
•
the vehicle is loaded on one side,
•
the wheels of an axle are loaded heavily (e.g. when towing a trailer or when driving
uphill or downhill),•
snow chains are mounted,
•
the temporary spare wheel is mounted,
•
one wheel per axle was changed.
Basic setting of tyre inflation pressure-control system After changing the tyre inflation pressures or after changing one or several wheels, the position of a wheel on the vehicle (e.g. ex
changing the wheels between the axles) or
when the warning light lights up while drivin
g, a basic setting of the system must be
carried out as follows.•
Inflate all tyres to the specified inflation pressure
⇒page 215.
•
Switch on the ignition.
•
Press button
⇒fig. 156
for more than 2 seconds. While pressing the button,
the warning light
 lights up. At the same time the memory of the system is erased
and the new calibration is started, which is confirmed with an audible signal and then the warning light
 goes out.
•
If the warning light
 does not go out after the basic
setting, there is a fault in the
system. Have the vehicle inspected by your nearest specialist garage. Warning light
 lights up
If the tyre inflation pressure of at least one
wheel is insufficiently inflated in comparison
to the stored basic va
lue, the warning light
 ⇒
lights up.
Warning light
 flashes
If the warning light flashes, there is a system fault. Have the vehicle inspected by your nearest specialist garage.
WARNING
•
When the warning light
 lights up, immediately reduce the speed and
avoid sudden steering and brake manoeuvr
es. Please stop the vehicle without
delay at the nearest possible stop and in
spect the tyres and their inflation pres-
sures.•
The driver is responsible for the correc
t tyre inflation pressures. For this
reason, the tyre inflation pressu
res must be checked regularly.
•
Under certain circumstances (e.g. sporty style of driving, wintry or unpaved
roads) the warning light
 can be delayed or does not light up at all.
•
The tyre inflation pressure-control system does not take away the respon-
sability from the driver for the
correct tyre inflation pressure.
