It is also possible under certain special accident situations that the front as well as
the side airbags and head airbags are deployed simultaneously.
The airbags are not deployed in the case of minor frontal and side collisions, rear-
end collisions, tilting of the vehicle, and vehicle rollover.
Deployment factors
It is not possible to state globally which deployment conditions apply to the airbag
system in every situation as the circumstances which exist in the case of acci-
dents vary greatly. An important role in this case, for example, is played by factors
such as the type of object against which the vehicle impacts (hard, soft), the angle
of impact, the vehicle speed etc.
A decisive factor for the deployment of the airbags is the deceleration which oc-
curs during a collision. The control unit analyses the nature of the collision and ac-
tivates the relevant restraint system. If the vehicle deceleration which occurs and
is measured during the collision remains below the prescribed reference values
specified in the control unit, the airbags are not deployed although the vehicle
may well suffer severe damage to the bodywork as a consequence of the acci-
dent.
The airbags are not deployed if:
● ignition is switched off;
● a minor frontal collision;
● a minor side collision;
● a rear-end collision;
● Rollover of the vehicle. Note
● A grey white or red, non-harmful gas is released when the airbag is inflated.
This is perfectly normal and is not an indication of a fire in the vehicle.
● In the event of an accident in which the airbags are deployed:
– the interior lighting comes on (if the switch for the interior light is in the
door contact position),
– the hazard warning light is switched on;
– all the doors are unlocked;
– the fuel supply to the engine is interrupted. Front airbags
Description of the front airbags The airbag system is not a substitute for the seat belt!
Fig. 97 Driver airbag in the steering wheel/front passenger airbag in the dash panel
The front airbag for the driver is housed in the steering wheel
⇒
 fig. 97 - left. The
front airbag for the front passenger is housed in the dash panel above the storage
compartment ⇒ fig. 97 - right. The installation positions are each marked with the
“AIRBAG” logo.
The front airbag system, in combination with three-point safety belts, offers addi-
tional protection for the head and chest area of the driver and front passenger in
the event of a frontal collision of major severity ⇒  in Important safety informa-
tion regarding the front airbag system

on page 112.
The airbag is not a substitute for the seat belt, but is part of the complete passive
vehicle safety concept. Please note that an airbag can only offer you optimal pro-
tection in combination with a seat belt which is fastened .
Apart from their normal protective function, a further task of the seat belts is to
also hold the driver and front passenger in a correct seated position in the event
of a frontal collision so as to enable the front airbags to offer the maximum pro-
tection.
You should therefore always fasten the seat belts, not only because this is re-
quired by law, but also for safety reasons and for your own protection ⇒ page 105,

Driving Tips
Intelligent Technology Electronic stability programme (ESP)
General General
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 car 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),
● Antilock brake system (ABS),
● Brake Assist,
● Uphill Start 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 al-
so processes additional measurement data which are supplied by highly sensitive
sensors: the rotational velocity of the vehicle about its vertical axis, the lateral ac-
celeration 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 constantly compared with the actual be-
haviour of the vehicle. If differences exist, such as the car 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 rear wheel of a vehicle which
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
instrument cluster.
The ESP system cannot be switched off, only the TCS system can be switched off
by pressing the button ⇒
 fig. 113. The warning light  ⇒ page 25 lights up if the
TCS system is switched off.
The warning light  lights up permanently if there is a fault in the ESP system.
The fact that the ESP system operates together with the ABS means that the ESP
warning light will also come on if the ABS system is not operating properly.
If the warning light  comes on immediately after starting the engine, the ESP
system can be switched off for technical reasons. In this case, the ESP system can
be switched on again by switching the ignition on and off. If the warning light
goes out, the ESP system is fully functional again. WARNING
It is also not possible for the ESP to overcome the physical limits of the vehi-
cle. 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 par-
ticularly 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
accident! Note
● All four wheels must be fitted with the same tyres in order to achieve prob-
lem-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 another combi-
nation of tyres and wheels) can influence the function of the ESP ⇒

Electronic Differential Lock (EDL)
The electronic differential lock prevents 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, acceler-
ate and climb a steep hill when the conditions of the road surface are unfavoura-
ble.
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 sen-
sors. 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 process 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 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. WARNING
● Carefully depress the accelerator when accelerating on uniformly slippery
road surfaces, such as ice and snow. 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 sur-
face 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 other-
wise - risk of an accident! Note
● If the ABS or ASR or, where applicable, ESP indicator light lights up, the EDl
may have a fault. Have the vehicle inspected by your specialist garage as soon as
you can.
● Changes to vehicle (e.g. on engine, on the brakes, on chassis or another combi-
nation of tyres and wheels) can influence the function of the EDL ⇒

Traction control system (TCS) The traction control system prevents the driven wheels from spin-
ning when accelerating.
Fig. 113 TCS switch
General
The TCS makes it much easier, and sometimes at all possible, to start off, acceler-
ate and climb a steep hill when the conditions of the road surface are unfavoura-
ble.
Operating principle
The TCS switches on automatically when the 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 sur-
face is automatically adapted by reducing the engine speed. The system operates
at all speeds.
The TCS operates in combination with the ABS ⇒ page 128, 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 instrument cluster when there is a fault on
the TCS  ⇒  page 24. £126
Intelligent Technology

During an intervention of the system, the TCS warning light flashes
 in the in-
strument cluster ⇒ page 25.
Switching off
You can switch the TCS off and on again as you wish by pressing the button
⇒ fig. 113. The TCS warning light lights up in the instrument cluster when the TCS
is switched off  ⇒
 page 24.
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 car free when it has become stuck.
then you should switch on the TCS again. 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! Note
● All four wheels must be fitted with the same tyres in order to achieve prob-
lem-free operation of the TCS. Differing rolling circumferences of the tyres can
lead to an undesirable reduction in the engine output.

nation of tyres and wheels) can influence the function of the TCS ⇒

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
necessary 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 brakes take full effect under certain con-
ditions 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 possible 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 with road salt if you have not
used the brakes for some considerable time beforehand. The layer of salt on the
brake discs and brake pads must first be rubbed off when you apply the brakes.
Corrosion
Corrosion on the brake discs and dirt on the bake pads occur if the vehicle has
been parked for a long period and if you do not make much use of the braking sys-
tem.
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 ga-
rage 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 high-
er brake pedal pressure required. £ 127

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 26, Brake system .WARNING
● Only apply the brakes for the purpose 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 oth-
erwise the braking system could run too hot.
● Allow for the fact that new brake pads do not achieve their full braking ef-
ficiency until approximately 200 kilometres. 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 pressure
on the brake pedal. This guideline also applies to any new brake pads installed
at a future date. CAUTION
● Never allow the brakes to rub by applying slight pressure if you do not wish to
brake the vehicle. This causes the brakes to overheat and can also result in a lon-
ger braking distance and excessive wear.
● Before negotiating a steep downhill section, please reduce your speed, shift
down into the next lower gear (manual gearbox) or select a lower driving stage
(automatic gearbox). This enables you to make full use of the braking power of
the vehicle and reduces the strain on the brakes. Any additional braking should be
done intermittently, not continuously. Note
The brake light flashes automatically in case of an emergency braking at speeds
greater than 60 km/h or with the intervention of the ABS, which lasts longer than
1.5 seconds. After the speed was reduced below 10 km/h or the vehicle was stop-
ped, the brake light stops flashing and the hazard warning light system switches
on. The hazard warning light system is switched off automatically after accelerat-
ing or driving off again. Brake booster The brake booster boosts the pressure which you generate with the brake pedal.
The necessary pressure is only generated 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.
● While stopping or braking with a vehicle with a petrol engine and manual
transmission in the low rev range, press down on the clutch pedal. If you fail
to do so, the result may be an impairment of the function of the power brake.
You will apply a greater force to the brake pedal which you are used to - dan-
ger of accident! 
Antilock brake system (ABS) ABS prevents the wheels locking when braking.
General
The ABS contributes significantly to enhancing the active safety of your vehicle.
Compared to a car not fitted with the ABS brake system, you are able to retain op-
timal steering ability even during a full brake application on a slippery road surface
because the wheels do not lock up.
You must not expect, however, that the braking distance will be shorter under all
circumstances as a result of the ABS. The 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 tending to lock. This control cycle is
noticeable 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 optimally control the brake applica-
tion in this braking range. Never interrupt the application of the brakes! £128
Intelligent Technology

As soon as the vehicle speed has increased to about 20 km/hour an automatic
test procedure is conducted during which you will be able to hear a pumping noise
for about 1 second.
WARNING
● The ABS can also not overcome the physical limits of your vehicle. Please
do not forget this, particularly when driving on icy or wet road surfaces. If the
ABS is operating within the control range, 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 oth-
erwise - risk of an accident!
● The normal braking system is still fully functional if there is an ABS fault.
Visit a specialist garage immediately and adjust your style of driving according
to the damage to the ABS as you will not know how great the damage is and
the limitation it is placing on the braking efficiency. Note
● A warning light comes on if a fault occurs in the ABS system  ⇒  page 25.
● Changes to vehicle (e.g. on engine, on the brakes, on chassis or another combi-
nation of tyres and wheels) can influence the function of the ABS ⇒

Accessories, changes and replacement of parts. 
Brake Assist During a severe brake application (e.g. if a hazard exists), the Brake Assist increa-
ses the braking force and thus makes it possible to rapidly produce the pressure
required in the brake system.
The majority of drivers do apply the brakes in good time in dangerous situations,
but do not depress the brake pedal with sufficient pressure. Consequently, it is
not possible for the car to achieve its maximum deceleration and the car covers a
greater distance than necessary.
The Brake Assist is activated by the very quick operation of the brake pedal. In
such cases, a much greater braking pressure exists than during a normal brake ap-
plication. This makes it possible, even with a relatively low resistance of the brake
pedal, to produce an adequate pressure in the brake system in the shortest possi-
ble time, which is required for maximum deceleration of the car. You must apply
the brake pedal firmly and hold it in this position in order to achieve the shortest
possible braking distance. The Brake Assist is able to help you achieve a shorter braking distance in emer-
gency situations by rapidly producing the pressure required in the brake system. It
fully exploits the attributes of the ABS. After you release the brake pedal, the
function of the Brake Assist is automatically switched off and the brakes operate
in the normal way.
WARNING
● The Brake Assist is also not able to overcome the physical limits of your car
in terms of the braking distance required.
● Adapt your speed to the conditions of the road surface and to the traffic
situation.
● The increased safety offered by the Brake Assist must not tempt you to
take a greater safety risk than otherwise.
● If a fault occurs in the ESP, the Brake Assist function is also deactivated
Further information on the ESP ⇒

 page 125. 
Uphill Start Assist The uphill start assist makes it easier to start off on steep hills. The system assists
a start off by holding the brake pressure produced by the brake pedal actuation
for approx. 2 seconds after releasing the brake pedal. The driver can therefore
move his foot from the brake pedal to the accelerator pedal and start off on the
slope, without having to actuate the handbrake. The brake pressure drops gradu-
ally the more you operate the accelerator pedal. If the vehicle does not start off
within 2 seconds, it starts to roll back.
The uphill start assist is active as of a 3 % slope, if the driver door is closed. It is
always active on slopes when in forward or reverse start off. When driving down-
hill, it is inactive. 
Electrohydraulic power steering The power steering enables you to steer the vehicle with less physical force.
The steering characteristics can be changed by a specialist garage.
You will place great stresses on the power steering system if the steering is
turned to full lock when the vehicle is stationary. Turning the steering to full lock
in such a situation will be accompanied by noises.
£ 129
Intelligent Technology Using the system Safety Driving Tips General Maintenance Breakdown assis-
tance Praktik Technical data

It is still possible to fully steer the vehicle if the power steering fails or if the en-
gine is not running (vehicle being towed in). The only difference is that greater
physical effort is required.
It is possible that the hydraulic pump of the power steering will not run due to the
low vehicle network voltage if the battery has gone flat and the engine must star-
ted with the help off jump leads. This condition will be indicated by lighting up of
the warning light.
The power steering operates again if the battery is charged to a specific range
when engine is running. It also operates again, if the engine can be started with
its own battery.
If there is a fault in the power steering, the warning light lights up in the instru-
ment cluster  ⇒  page 20. WARNING
Contact your specialist garage if the power steering is defective. CAUTION
Never leave the steering wheel at full lock for more than 15 seconds when the en-
gine is running - risk of damaging the power steering! 
Tyre pressure monitoring system Fig. 114 Button for setting the tyre in-
flation pressure control valueThe tyre pressure monitoring 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
 in the instrument clus-
ter ⇒ page 24 and an acoustic 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 the system
After changing the tyre inflation pressures, after changing one or several wheels,
the position of a wheel on the vehicle (e.g. exchanging the wheels between the
axles) or when the warning light lights up while driving, a basic setting of the sys-
tem must be carried out as follows.
● Inflate all tyres to the specified inflation pressure ⇒
 page 161.
● Switch on the ignition.
● Press button 

⇒  fig. 114
for more than 2 seconds. While pressing the but-
ton, 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 sig-
nal 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 com-
parison to the stored basic value, the warning light  ⇒  lights up.

If the warning light flashes, there is a system fault. Have the vehicle inspected by
your nearest specialist garage. £130
Intelligent Technology

WARNING
● When the warning light  lights up, immediately reduce the speed and
avoid sudden steering and brake manoeuvres. Please stop the vehicle without
delay at the nearest possible stop and inspect the tyres and their inflation
pressures.
● The driver is responsible for the correct tyre inflation pressures. For this
reason, the tyre inflation pressures 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 pressure monitoring system does not take away the responsibility
from the driver for the correct tyre inflation pressure. Note
The tyre pressure monitoring system:
● does not replace the regular tyre inflation pressure control, because the sys-
tem cannot detect an even pressure loss,
● cannot warn in case of very rapid tyre inflation pressure loss, e.g. in case of
sudden tyre damage. In this case carefully bring the vehicle to a standstill without
sudden steering movements and without sharp braking.
● In order to ensure a proper functioning of the tyre inflation pressure-control
system, it is necessary to carry out the basic setting again every 10 000 km or 1x a
year. 
Diesel particle filter (diesel engine) In the diesel particle filter the resulting soot particles are collected
and burnt during the combustion of diesel fuel. Fig. 115 Vehicle data stickerCode 7GG
, 7MB or 7MG on the vehicle data sticker, see ⇒ fig. 115, indicates that
your vehicle is equipped with a diesel particle filter. The vehicle data sticker is lo-
cated on the floor of the luggage compartment and is also stated in the Service
schedule.
The diesel particle filter filters the soot particles completely from the exhaust. The
soot is collected in the diesel particle filter and burnt regularly. To assist this pro-
cedure, we recommend not to drive regularly over short distances.
If the diesel particle filter is clogged or there is a fault, it is indicated by the warn-
ing light  ⇒
 page 27, Diesel particle filter  (diesel engine). WARNING
● The diesel particle filter achieves very high temperatures. Therefore do not
park at points where the hot filter comes into direct contact with dry grass or
other combustible materials - risk of fire!
● Never use additional underbody protection or corrosion-protection agents
for the exhaust pipes, catalytic converters, diesel particle filter or heat shields.
When the engine reaches its operating temperature, these materials might ig-
nite – risk of fire. Note
When using diesel fuel with high sulphur content the life of the diesel particle fil-
ter is clearly reduced. A specialist garage will be able to tell you which countries
use only diesel fuel with high sulphur content.  131
