The effectiveness of the brakes can also be tem­
porarily reduced if the car is driven for some dis­
tance without using the brakes when there is a
lot of salt on the road in winter. The layer of salt
that accumulates on the discs and pads can be re­
moved 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 corro­
sion 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 immediately 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 al­
low 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 de­
posits on the pads and discs, select a clear,
dry road. Be sure not to inconvenience or en­
danger other road users; do not risk an acci­
dent.
- Never let the car coast with the engine
switched off (this can cause accidents).
102 CD
CAUTION
- Never let the brakes "drag" by leaving your
foot on the pedal when you do not really in­
tend to brake. This overheats the brakes, re­
sulting 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 ef­
fect 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, you must
apply considerably more pressure to the
brake pedal than you normally would.
- 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.
Electronic stabilisation
control (ESC)
Description
The electronic stabilisation control (ES() increa­
ses the car's stability. It reduces the tendency to
skid and improves the stability and road holding
of the vehicle. The ESC detects critical handling
situations, such as understeer, oversteer and
wheelspin on the driven wheels. It stabilises the
vehicle by braking individual wheels or by reduc­
ing the engine torque. The indicator lamp Ii] in
the instrument cluster starts flashing as soon as
the ESC intervenes.
The following systems are integrated in the ESC:
Anti-lock brake system (ABS)
ABS prevents the wheels from locking up under
braking until the vehicle has reached a virtual
standstill. You can continue to steer the vehicle
even when the brakes are on full. Keep your foot

ly to retract the rear spoiler all the way back.
& WARNING
- When extending or retracting the rear spoil­
er, please make sure that no persons or ob­
jects are close to the moving spoiler -risk of
injury!
- If the indicator lamp (M appears, the rear
spoiler may have failed to extend due to a
malfunction. In this case, the car's handling
may be different at high speeds. Drive to a
qualified workshop without delay (but do
not exceed 140 km/h) and have the fault
rectified.
CD CAUTION
- If you need to push the vehicle, never put
your weight on the rear spoiler -Risk of
damage!
- To avoid damage to the rear spoiler, you
should not lean on it or apply any other type
of pressure.
- Do not operate the rear spoiler manually
when the boot lid is open or any moving
parts of the automatic rear spoiler are ob­
structed -risk of damage!
Note
Clean the rear spoiler housing every 2 to 3
months. The rear spoiler housing must be free
of ice, snow and leaves in order to operate
correctly.
106 Power
management
This system helps to ensure reliable
starting
The power management controls the distribu­
tion of electrical energy and thus helps to ensure
that
there
is always enough power available to
start the engine.
If a vehicle with a conventional electrical system
is left parked for a long time, the battery will
gradually lose its charge because certain electri­
cal equipment (such as the immobiliser) contin­
ues to draw current even when the ignition is off.
In some cases there may not be enough power
available to start the engine.
Your vehicle is equipped with an intelligent pow­
er management system to control the distribu­
tion of electrical energy. This significantly im­
proves reliability when starting the engine, and
also prolongs the life of the battery.
The main functions incorporated in the power
management system are battery diagnosis, re­
sidual current management and dynamic power
management.
Battery diagnosis
The battery diagnosis function constantly regis­
ters the condition of the battery. Sensors detect
the battery voltage, battery current and battery
temperature. This enables the system to calcu­
late the current power level and charge condition
of the battery.
Residual current management
The residual current management reduces power
consumption while the vehicle is parked. It con­
trols the supply of power to the various electrical
components while the ignition is switched off.
The system takes the battery diagnosis data into
consideration.
Depending on the power level of the battery, the
individual electrical components are switched off
one after the other to prevent the battery from
losing too much charge and to ensure that the
engine can be started reliably.

Never spill fluids on a hot engine. These flu­
ids can cause a fire (e.g. radiator anti­
freeze).
- Take care not to cause short circuits in the
electrical system, especially when working
on the battery.
- When working in the engine compartment
be aware that the radiator fan may start
running suddenly, even if the ignition is
switched off-risk of injury!
- Do not unscrew the cap on the expansion
tank when the engine is hot. The cooling
system is under pressure.
- Protect face, hands and arms by covering
the cap with a large, thick rag to protect
against escaping coolant and steam.

of burns!
- If any tests have to be performed with the
engine running, there is an extra safety risk
from the rotating parts, such as the drive
belts, alternator and radiator fan, etc., and
from the high-voltage ignition system.
- Vehicles with automatic gearbox: Never
open the throttle inadvertently (for instance
by hand from the engine compartment) if a
gear is engaged while the vehicle is station­
ary with the engine running. The vehicle
could otherwise start moving immediately
and possibly cause an accident.

CD CAUTION
- Have your qualified workshop check the
cooling system before the winter season to
make sure that the anti-freeze concentra­
tion is adequate for the conditions to be ex­
pected. This applies particularly if you drive
into a colder climate zone.
- To prevent damage to the engine, do not
use a different type of anti-freeze additive if
the approved type of additive is not availa­
ble. In this case use only water and bring
the coolant concentration back up to the
correct level as soon as possible by putting
in the specified additive.
- Always top up with fresh, unused coolant.
- Radiator sealants must not be added to the
coolant.
Topping up coolant
Fig. 214 Engine compartment: Cap of coolant expansion
tank
Checking coolant level
.. Park
your vehicle on a level surface .
.. Switch off the ignition .
.. Read off the coolant level on the coolant expan­
sion tank ¢ page 222, Fig. 211. When the en­
gine is cold, the coolant level should be be­
tween the marks. When the engine is warm, it
may be slightly above the top mark. Checking
and topping up fluids
Topping up coolant
Impor tant: The coolant expansion tank must not
be empty ¢(D.
.. Wait for the engine to cool down.
.. Cover the cap on the expansion tank with a
cloth, and carefully unscrew the cap anti-clock­
wise ¢ .&_ .
.. Add coolant in the correct concentration
¢ page 224 up to the top mark.
.. You should make sure that the fluid level re-
mains stable. If necessary, add more coolant.
.. Screw the cap on again tightly.
Any loss of coolant normally indicates a leak in
the cooling system. Drive to a qualified workshop
without delay and have the cooling system
checked. If there are no leaks in the system, a
loss of coolant can only occur if the coolant boils
and is forced out of the system as a result of
overheating.
A WARNING
- The cooling system is under pressure. Do
not unscrew the cap on the expansion tank
when the engine is hot: you could be scal­
ded by escaping steam.
- The coolant and coolant additive can be a
health hazard. Store the coolant additive in
the original container in a safe place out of
reach of children -risk of poisoning.
- When working in the engine compartment
be aware that the radiator fan may start
running suddenly, even if the ignition is
switched off-risk of injury!
CD CAUTION
Do not add coolant if the expansion tank is
empty. Air could have got into the cooling sys­
tem -risk of engine damage! In this case, do
NOT drive on. Obtain professional assistance .
