Possible alternatives for securing a child safety seat
A child safety seat can be secured on the rear seats and
on the front passenger's seat.The following alternatives are avai lable for safely securing a child
safety seat on the rear seats and on the front passenger's seat.•
Child safety seats of the categories 0 to 3 can be secured with the
standard three-point seat belts.
•
Child safety seats of the categories 0, 0+ and 1 with the “ISOFIX”
system can be secured without seat belts using the “ ISOFIX”
retainers* ⇒page 191 .
Compatibility of vehicle seat positions for child safety seats
(according to EC directive 77/541):
“universally compatible”
The front passenger's backrest must be set as far forward as
possible or adapted to the child safety seat as required, and the
seat height must be adjust ed to its highest position.
The front passenger's airbag must be deactivated if a rearward-
facing child seat is used.
The front passenger's seat can be equipped with optional
“ ISOFIX ” retainers.
The rear seats can be equipped with optional “ ISOFIX” retainers.
WARNING
While the vehicle is moving, chi ldren must always be protected
with a restraint system which is suited to their age, height and
weight. Please refer to the chapter “Child seat categories”.•
Never install a rearward-facing child safety seat on the front
passenger's seat unless the fr ont passenger's airbag has been
deactivated. This could result in potentially fatal injuries. If you
have no alternative but to let a child travel on the front passenger's
seat, the front passenger's airb ag must be deactivated before-
hand. Please refer to the chapter “Deactivating airbags”.
•
Note the important information and warnings concerning the
use of child safety seats found in the chapter “Important safety
notes when using child safety seats” and in the installation
instructions provided by the manufactur er of the child safety
seat.

Switching off
The ESP should normally be left switched on at all times. If required,
you can press the ESP OFF button to switch off the traction control
system (ASR) or the electronic stabilisation program (ESP).
•
Switching off the traction control system (ASR):
Press the ESP
button briefly. The traction control system (ASR) can be switched off
in special driving conditions, e.g. if you are driving with snow chains
⇒ page 198 . The message ASR off will appear in the display.
•
Switching off the ESP/traction control system (ASR): Press the
ESP button for longer than 3 seconds. The ESP/ASR warning lamp
lights up when the system is switched off, see ⇒page 16 . The
message ESP switched off will appear in the display.
WARNING
•
The ESP is not able to overcome th e physical limits of adhesion.
Even with ESP, you sh ould always adjust your speed to suit the
conditions. Please bear this in mind, especially on wet or slippery
road surfaces. Do not let the extr a safety provided tempt you into
taking any risks when drivin g – this can cause accidents.
•
Please note that, when the ESP or ESP/traction control system
(ASR) is switched off, the driven wheels may start to spin, causing
the vehicle to lose grip, in part icular on slippery or wet roads -
danger of skidding!
Anti-lock brake system (ABS)
ABS prevents the wheels from locking up under braking.The anti-lock brake system (ABS) is an important part of the car's
active safety system. However, the ABS will not necessarily guar-
antee shorter stopping distances in all conditions. For instance, on
loose gravel or fresh snow on top of an icy surface (conditions which
anyway require extreme care and reduced speed), the stopping
distance with ABS may even be slightly longer. How the ABS works
The system runs an automatic self-check when the car reaches a
road speed of about 6 km/h. This may be accompanied by a noise
from the ABS pump.
If one of the wheels is turning too slowly in relation to the road
speed, and is close to locking up, the system will reduce the pres-
sure in the brake line to this wheel. The driver is made aware of this
control process by a
pulsating of the brake pedal and accompa-
nying noise. This is a deliberate warning to the driver that one or
more of the wheels is tending to lock up and the ABS control func-
tion has intervened. In this situation it is important to keep the brake
pedal fully depressed so the ABS can regulate the brake application
- do not “pump” the brake pedal.
WARNING
The grip provided by ABS is still su bject to the physical limits of
adhesion. Always bear this in mind, especially on wet or slippery
roads. If you notice that the AB S is working (to counteract locked
wheels under braking), you should reduce speed immediately to
suit the road and traffic conditio ns. Do not let the extra safety
provided tempt you into taking an y risks when driving – this can
cause accidents.
Note
If a malfunction should occur in the ABS, this is indicated by a
warning lamp ⇒page 18 .Brake assist system
The brake assist system helps the driver to achieve
optimum braking effect.The brake assist system helps to increase braking power and thus to
achieve a shorter stopping distance . If the driver presses the brake

198pedal very quickly, the brake assist system automatically boosts the
braking force to the maximum level, up to the point where the anti-
lock brake function (ABS) intervenes to stop the wheels from
locking. You should then keep the brake pedal pressed until the
vehicle has braked to the required speed. The brake assist system
switches itself off as soon as you release the brake pedal.
The brake assist system will not be operative if there is a malfunc-
tion in the ABS.
WARNING
Please remember that the accident risk always increases if you
drive too fast, especially in corners or on a slippery road, or if you
follow too close behind the vehicle in front of you. An increased
accident risk cannot be compensated even by the brake assist
system, so always be sure to maintain a safe speed.Traction control system (ASR)
The traction control system prevents the driven wheels
from spinning when the car is accelerating.General notes
The traction control system (ASR) is one of the functions incorpo-
rated in the electronic stabilisation program (ESP).
The traction control system (ASR) helps the car to start moving,
accelerate and climb a gradient in slippery conditions where this
may otherwise be difficult or even impossible.
How the system works
The ASR acts automatically i.e. without the driver's intervention.
With the aid of the ABS sensors ⇒page 197 , the ASR monitors the
speed of the driven wheels. If the wheels start to spin, the engine
power is reduced automatically to match the amount of grip avail-
able. The system works at all speeds. The ASR works in conjunction with the ABS. If a malfunction should
occur in the ABS, the ASR will also be out of action.
Switching on
The ESP is switched on automatically when the engine is started
and performs a self-test routine. As soon as this routine is complete,
the system switches back to normal operating mode. If the traction
control system (ASR) has been deactivated (for one of the reasons
noted below) you can switch it back on manually by pressing the
switch
⇒page 196, fig. 203. The message ESP/ASR on will appear
briefly in the display. If the traction control system (ASR) has been
deactivated, it will switch back on automatically at a speed of about
70 km/h on vehicles with front-wheel drive.
You can switch the traction control system (ASR) on again if neces-
sary by pressing the switch ⇒page 196, fig. 203.
Switching off
If required, the ASR can also be switched off manually by pressing
the switch briefly ⇒page 196, fig. 203 (for less than 3 seconds). The
ESP warning lamp lights up when the traction control system (ASR)
is switched off, see ⇒page 16 . The message ASR off will appear in
the display. For safety reasons, the system can only be switched off
at speeds below 50 km/h on vehicl es with front-wheel drive. The
ASR can be deactivated at any speed on vehicles with four-wheel
drive.
The traction control system should normally remain switched on at
all times. It should only be switched off manually in particular
circumstances where a certain amount of wheel slip may be desir-
able. For example:
•
when driving with snow chains
•
when driving in deep snow or on loose surfaces
•
when rocking the car backwards and forwards to free it.
The ASR should be switched on again afterwards as soon as
possible.

Technical data
Note
To ensure that the ASR works properly, all four wheels must be fitted
with identical tyres. Any differences in the rolling radius of the tyres
can cause the system to reduce engine power when this is not
desired. Also refer to ⇒page 245, “Replacing wheels and tyres”.Electronic differential lock (EDL)
The electronic differential lock monitors the speed of the
driven wheels.General notes
The electronic differential lock (EDL) helps the car to start moving,
accelerate and climb a gradient in slippery conditions where this
may otherwise be difficult or even impossible.
How the system works
The EDL acts automatically. With the aid of the ABS sensors
⇒page 197 , the system monitors the rotational speed of the driven
wheels on each axle. Whenever it detects a significant difference in
the speed of the driven wheels of one axle (for example, if the road is
slippery on one side ) the system applies the brake to slow down the
spinning wheel so that more of the power is directed to the other
wheel of this axle (or to the three other wheels on vehicles with four-
wheel drive). This function is active up to about 100 km/h. The brake
system will make noises while it is working.
Driving away from a standstill
Sometimes one wheel has less grip and starts spinning, for
example, if one of the driven wheels is on ice. In this case, keep
pressing the accelerator gradually until the car starts moving, even
though the wheel with less grip will still spin.
Overheating of the brakes
To prevent the disc brake of the braked wheel from overheating, the
EDL cuts out automatically if subjected to excessive loads. The car remains operational and will behave in the same way as a car
without EDL.
The EDL will switch on again automatically when the brake has
cooled down.
WARNING
•
When accelerating on a uniforml
y slippery surface (for instance
all four wheels on ice or snow), press the accelerator gradually and
carefully. The driven wheels may ot herwise start to spin (in spite
of the EDL), which would impair th e car's stability and could lead
to an accident.
•
Even with EDL, you should always adjust your speed to suit the
conditions. Do not let the extr a safety provided tempt you into
taking any risks when drivin g – this can cause accidents.Note
If the ABS warning lamp lights up, th is can also mean there is a fault
in the EDL. Please contact a qualified workshop as soon as
possible.BrakesNew brake pads
New brake pads do not give full br aking effect for the first 400 km,
they must first be “bedded in”. However, you can compensate for
the slightly reduced braking effect by applying more pressure on
the brake pedal. Avoid placing a heavy load on the brakes during the
running-in period.
We ar
The rate of wear on the brake pads depends a great deal on how you
drive and the conditions in which the vehicle is operated. Negative

200factors are, for instance, city tra ffic, frequent short trips or hard
driving with abrupt starts and stops.
Wet roads; road salt
When you are driving at a speed higher than 80 km/h and have the
windscreen wipers switched on the brake pads are very briefly
brought into contact with the brak e discs. This automatic process
which goes unnoticed by the driver is carried out at regular intervals
and is intended to improve braking response in wet conditions.
In certain conditions, such as in heavy rain, or after washing the car
or driving through water, the full braking effect can be delayed by
moisture (or in winter by ice) on the discs and brake pads. The
brakes should be “dried” by pressing the pedal to restore full
braking effect.
The effectiveness of the brakes can also be temporarily reduced if
the car is driven for some distance without using the brakes when
there is a lot of salt on the road in winter. The layer of salt that accu-
mulates on the discs and pads can be removed with a few cautious
brake applications.
Corrosion
There may be a tendency for dirt to build up on the brake pads and
corrosion to form on the discs if the car is used infrequently, or if
you only drive low mileages without using the brakes very much.
If the brakes are not used frequently, or if corrosion has formed on
the discs, it is advisable to clean off the pads and discs by braking
firmly a few times from a moderately high speed ⇒.
Faults in the brake system
If the brake pedal travel should ever increase suddenly, this may
mean that one of the two brake circuits has failed. Drive immedi-
ately to the nearest qualified workshop and have the fault rectified.
On the way to the dealer, be prepared to use more pressure on the
brake pedal and allow for longer stopping distances. Low brake fluid level
Malfunctions can occur in the brake system if the brake fluid level is
too low. The brake fluid level is monitored electronically.
Brake servo
The brake servo amplifies the pressure you apply to the brake pedal.
It only works when the engine is running.
WARNING
•
When applying the brakes to
clean off deposits on the pads and
discs, select a clear, dry road. Be sure not to inconvenience or
endanger other road users; do not risk an accident.
•
Never let the car coast with the engine switched off (this can
cause accidents).Caution
•
Never let the brakes “drag” by leaving your foot on the pedal
when you do not really intend to brake. This overheats the brakes,
resulting in longer stopping distances and greater wear.
•
Before driving down a long, steep gradient, it is advisable to
reduce speed and move the selector lever to a lower gear. In this
way you will make use of the engine braking effect and relieve the
load on the brakes. If you still have to use the brakes, it is better to
brake firmly at intervals than to apply the brakes continuously.Note
•
If the brake servo is out of action due to a malfunction, or if the
car has to be towed, you will have to press the brake pedal consid-
erably harder to make up for the lack of servo assistance.
•
If you wish to equip the car with accessories such as a front
spoiler or wheel covers, it is important that the flow of air to the
front wheels is not obstructed, otherwise the brakes can overheat.
