78•If the brake warning lamp lights up together with the ABS warning
lamp, this can mean that there is a fault in the ABS control function. As a
result, the rear wheels can lock relatively easily when braking. Under
certain circumstances, the rear of the vehicle could suddenly sway from
side to side, with the subsequent dang er of skidding. Drive carefully to the
nearest specialised workshop and have the fault repaired.
Fault in the cooling system
Faults in the cooling system must be repaired immediately.If the
symbol flashes in the display, this means that either the
coolant temperature is too high or the coolant level is too low. The
following message will appear in the display together with the
symbol:
Switch off engine and check coolant level
– Stop the vehicle.
– Switch the engine off.
– Check the coolant level ⇒page 234.
– Add more coolant if necessary ⇒page 235.
– Wait for the symbol to go out before driving on.
– Obtain professional assistance if necessary.
If the coolant level is correct, the overheating may be caused by a malfunction
of the radiator fan. If the alternator warning lamp lights up as well
⇒page 69, it is possible that
the drive belt has broken.
Caution
Do not drive on if the symbol
v has come on to indicate a fault in the cooling
system, otherwise there is a risk of engine damage.
Engine oil pressure too low
E
If the engine oil pressure is too low the fault must be repaired
immediately.If the
E
symbol flashes in the display, the oil pressure is too low.
The following message will appear in the display together with the
symbol:
Switch off engine, check oil level
– Stop the vehicle.
– Switch the engine off.
– Check the engine oil level ⇒page 232.
– Obtain professional assistance if necessary.
Engine oil level too low
If the engine oil level is too low, add more oil ⇒page 233.
Engine oil level correct
If the
E symbol flashes and the engine oil level is correct, obtain profes-
sional assistance. Do not drive on! Do not continue to run the engine, even at
idle speed .

Driving
176•The brake servo and the power steering system work only when the
engine is running. You need more strength to steer and brake the vehicle
when the engine is switched off. Given that you will be unable to steer and
brake as usual, this could lead to a risk of accidents and injuries.Caution
If the engine has been running under high load for a long time, there is a risk
of heat building up in the engine compartment after the engine has been
switched off; this could cause engine damage. Therefore, you should let the
engine idle for approximately 2 minutes before you switch it off.
Note
After the engine is switched off the radiator fan may run on for up to 10
minutes, even if the ignition is switched off. It may also start running again
after some time if the coolant temperature rises due to a build-up of heat
under the bonnet, or if the engine is already warm and the engine compart-
ment is heated up further by direct sunlight.
HandbrakeHandbrake
The handbrake should be applied firmly to prevent the
vehicle from accidentally rolling away.Applying the handbrake
– Pull the handbrake lever up all the way.
Releasing the handbrake
– Pull the lever up slightly and at the same time press in the release
button ⇒fig. 149 -arrow-.
– Keep the release button pressed and push the lever all the way down ⇒ .

Vehicle maintenance and cleaning
220Cleaning the engine compartment
Take special care when cleaning the engine compartment.Anti-corrosion treatment
The engine compartment and the surface of the power unit are given anti-
corrosion treatment at the factory.

is frequently driven on salted roads. To prevent the salt corroding the vehicle,
the entire engine compartment should be thoroughly cleaned before and
after winter.
Yo u r A u t h o r i s e d S e r v i ce Ce n t r e has got the necessary equipment to provide
the correct cleaning and preserving products. For this reason, we recommend
having this work performed by them.
The anti-corrosion protection is usually removed if the engine compartment
is cleaned with grease removing solutions, or if you have the engine cleaned.
On commissioning this work, ensure that all surfaces, seams, joints and
components in the engine compartment are given anti-corrosion treatment.
WARNING
•When working in the engine compartment, always observe the safety
warnings ⇒page 229.•Before opening the bonnet, switch the engine off, apply the handbrake
firmly and always remove the key from the ignition.•Allow the engine to cool before you clean the engine compartment.•Do not clean the vehicle underbody, wheel arches or wheel trims
without protecting your hands and arms. You may cut yourself on sharp-
edged metal parts. Failure to comply could result in injury.•Moisture, ice and salt on the brakes may affect braking efficiency. Risk
of accident. Directly after washing, avoid sudden and sharp braking.
•Never touch the radiator fan. It is temperature-controlled and could
start automatically, even when the key is removed from the ignition!For the sake of the environment
Fuel, grease and oil deposits could be removed when the engine is washed.
The polluted water must be cleaned in an oil separator. For this reason,
engine washing should be carried out only by a qualified workshop or a petrol
station.Vehicle interior maintenancePlastic parts and dash panel cleaning– Use a clean, damp cloth to clean plastic parts and the dash panel.
– If this does not provide satisfactory results, use a special solvent-free plastic cleaning product.
WARNING
Never clean the dash panel and the airbag module surface with cleaners
containing solvents. Solvents cause the surface to become porous. If the
airbag triggered, plastic parts could become detached and cause injuries.
Caution
Cleaning products which contain solvents will damage the material.

230•Never touch the radiator fan while the engine is hot, as the fan could
start up suddenly.•Never open the expansion tank when the engine is hot. The cooling
system is under pressure.•Protect face, hands and arms from any hot steam or hot coolant fluid
released by covering the cap with a large, thick rag when opening the
expansion tank.•If any tests have to be performed with the engine running, there is an
added safety risk from the rotating parts (e.g. drive belts, alternator, radi-
ator fan, etc.) and from the high-voltage ignition system.•Observe the following additional warnings if work on the fuel system or
the electrical system is necessary:
−Always disconnect the battery.
− Do not smoke.
− Never work near open flames.
− Always keep an approved fire extinguisher immediately available.Caution
When topping up fluids, make sure the correct fluid is put into the correct
filler opening. This can otherwise cause serious malfunctions or engine
damage.
For the sake of the environment
Inspect the ground underneath your vehicle regularly so that any leaks are
detected at an early stage. If you find spots of oil or other fluids, have your
vehicle inspected at the workshop.
Note
On right-hand drive vehicles some of the reservoirs mentioned below are
located on the other side of the engine compartment.Closing the bonnet– To close the bonnet, push it down until it overcomes the spring
pressure.
– Let the bonnet engage in the locking part. Do not force it ⇒ .
WARNING
•For safety reasons the bonnet must always be completely closed when
the vehicle is moving. After closing it always check that it is properly
secured. The bonnet must be flush with the adjacent body panels.•Should you notice that the bonnet is not safely secured when the
vehicle is moving, stop the vehicle immediately and close the bonnet.
Failure to do so could result in an accident.
Engine oilGeneral notesThe engine comes with a special, high quality, multi grade oil that can be
used in all seasons of the year except for those regions affected by extreme
cold.

Safety First
Operating Instructions
Practical Tips
Technical Specifications
The coolant level should be checked with the engine switched off.
The coolant level is monitored by a warning lamp on the instrument panel
display
⇒page 78. However, we recommend that it should be checked occa-
sionally.
Coolant fluid loss
Any loss of coolant fluid normally indicates a leak in the cooling system. In
this case the cooling system should be inspected by a qualified workshop
without delay. It is not sufficient merely to top up the coolant fluid.
If there are no leaks in the system, a loss of coolant fluid can only occur if the
coolant boils and is forced out of the system as a result of overheating.
Caution
Radiator sealants must not be added to the coolant fluid. Such additives
could seriously impair the function of the cooling system.Topping up the coolant fluid
Be careful when topping up with coolant fluid.– Switch the engine off.
– Wait for the engine to cool down.
– Cover the cap on the expansion tank ⇒fig. 179 with a cloth, and
carefully unscrew the cap anti-clockwise ⇒.
– Add coolant fluid.
– Screw on the cap tightly.
Make sure that the coolant fluid meets the required specifications
⇒page 233, “Coolant fluid”. Do not use a different type of antifreeze if
G12++ antifreeze is not available. In this case, use only water and bring the
antifreeze concentration back up to the correct level as soon as possible.
Always top up with new coolant fluid.
Do not fill above the “max” mark. Excess coolant fluid is forced out of the
system through the valve in the filler cap when the engine gets hot.
If a lot of coolant fluid has been lost, wait for the engine to cool down before
putting in cold coolant. Failure to do so could result in serious engine
damage.
WARNING
•The cooling system is under pressure. Do not unscrew the cap on the
expansion tank when the engine is hot. Failure to comply could result in
burns.•The antifreeze and coolant fluid can be a health hazard. Therefore, the
antifreeze should be stored in the original container in a safe place out of
reach of children. Failure to comply could result in poisoning.For the sake of the environment
Drained off coolant should not be used again. Drain off the used coolant into
a suitable container and dispose of it in the proper manner (observe environ-
mental regulations).

The radiator fan can start running spontaneously.The auxiliary fan can continue to run for as long as 10 minutes after stopping
the engine, even after the ignition is switched off. It may also start running
suddenly ⇒ after some while if•Stored heat raises the coolant temperature, or•The hot engine compartment is additionally heated up by the sun.WARNING
When working in the engine compartment be aware that the radiator fan
may start running suddenly, leading to the risk of injury.
Washer fluid and windscreen wiper bladesWindscreen washer system
Plain water is not sufficient for the windscreen washer
system.The container for the windscreen washer contains the cleaning fluid for the
windscreen and the headlight washer system*. The container is located in the
engine compartment (front left). The fi ller cap is marked with the symbol
W
⇒ fig. 180.
The capacity of the container is listed in ⇒page 301.
Plain water on its own is not enough to clean the glass properly. It is therefore
advisable to add a suitable washer fluid additive (with wax solvent) to the
water. A washer fluid with freeze-resistant additive should be used in winter.
