64Coolant temperature too high
First look at the coolant temperature gauge. The coolant temperature is too 
high if the needle is over the warning area on the dial.  Stop the vehicle, 
switch off the engine and wait for it to cool down. Check the coolant level.
If the coolant level is correct, the overheating may be caused by a malfunction 
of the radiator fan. Check the radiator fan fuse and have it replaced if neces-
sary  ⇒page 213.
If the warning lamp lights up again  after driving on for a short distance,  stop 
the vehicle and switch off the engine. Contact an Authorised Service Centre 
or a qualified workshop.
Coolant level too low
First look at the coolant temperature gauge. If the needle is in the normal 
range, top up with coolant at the earliest opportunity  ⇒.
WARNING
•
If your vehicle is immobilised for any technical reasons, move it to a 
safe distance from traffic. Turn off the engine, turn on the hazard lights and 
place the warning triangle.
•
Never open the bonnet if you can see or hear steam or coolant escaping 
from the engine compartment. Risk of scalding. Wait until you can no 
longer see or hear escaping steam or coolant.
•
The engine compartment of any motor vehicle is a dangerous area! 
Before carrying out any work in the engine compartment, switch off the 
engine and allow it to cool down. Alwa ys note the corresponding warnings 
⇒ page 180.
Main beam headlights 
This warning lamp lights up when the main beams are on.The warning lamp 
 lights up when the main beams are on or when the 
headlight flasher is operated.
Further information  ⇒page 93.
Fuel level / reserve 
This symbol lights up to indicate that the fuel tank is down to 
the reserve level.This lights when only 7 litres of  fuel remain in the tank. Also, an  audible 
warning  is given. This serves as a reminder to fill up with fuel at the earliest 
opportunity  ⇒page 177.Anti-lock brake system (ABS) 
 
A warning lamp system monitors the ABS.
The warning lamp 
 should light up for a few seconds when the ignition is 
switched on. It goes out again after the system has run through an automatic 
test sequence.
There is a fault in the ABS if:
•
The warning lamp 
 does not light up when the ignition is switched on.
•
The warning lamp does not go  out again after a few seconds.
•
The warning lamp lights up when the vehicle is moving.

Glow plug system for the diesel engine
To avoid unnecessary load on the battery, do not use any other major elec-
trical equipment while the 
glow plugs are pre-heating.
Start the engine as soon as  the glow plug warning lamp  ⇒page 63 goes out.
Starting the engine after the fuel tank has been completely run dry
If the fuel tank has been completely ru n dry, it may take longer than normal 
(up to one minute) to start the engine af ter refuelling with diesel fuel. This is 
because the system must eliminate air first.
WARNING
•
Never start or run the engine in unventilated or closed rooms. The 
exhaust fumes contain carbon monoxide, an odourless and colourless 
poisonous gas. Risk of fatal accidents. Carbon monoxide can cause loss of 
consciousness. It can also cause death.
•
Never leave the vehicle unattended if the engine is running.
•
Never use “cold start sprays”, they could explode or cause the engine 
to run at high revs. Risk of injury.Caution
•
When the engine is cold, you should avo id high engine speeds, driving at 
full throttle and over-loading th e engine. Risk of engine damage.
•
The vehicle should not be pushed or  towed for more than approximately 
50 metres to start the engine. Fuel could enter the catalytic converter and 
damage it.
•
Before attempting to push-start or tow a vehicle to start it, you should first 
try to start it using the battery of another vehicle. Note and follow the instruc-
tions ⇒ page 230, “Jump-starting”.
For the sake of the environment
Do not warm-up the engine by running th e engine with the vehicle stationary. 
You should drive off as soon as you start the engine. This helps the engine 
reach operating temperature faster and reduces emissions.Switching off the engine– Stopping the engine.
– Turn the ignition key to position  ⇒page 132, fig. 100   .After the engine is switched off the  radiator fan may run on for up to 10 
minutes, even if the ignition is switched of f. It is also possible that it will turn 
itself on once more if the temperature of the coolant increases due to the 
elimination of built up heat in the engine  compartment or if this is heated due 
to prolonged exposure to the heat of the sun.
WARNING
•
Never switch off the engine until the vehicle is stationary.
•
The brake servo works only when the engine is running. You will need 
more strength to brake the vehicle when the engine is switched off. As you 
cannot brake in the normal manner, there is a greater risk of accidents and 
serious injury.
•
The steering lock can engage immediately when the key is removed 
from the ignition lock. The vehicle cannot be steered. Risk of accident.

Cleaning and caring for your vehicle169
Safety First
Operating instructions
Tips and Maintenance
Te c h n i c a l  D a t a
Underbody sealant
The underside of the vehicle is coated to protect it from corro-
sion and damage.The protective coating could be damaged when driving. We recommend that 
the protective coating under the body and on the running gear should be 
checked, and reinstated if necessary, before and after the winter season.
We recommend that repair work and additional anti-corrosion work is carried 
out by your Authorised Service Centre.
WARNING
Do not apply underseal or anti-corrosion coatings to the exhaust pipes, 
catalytic converter or the heat shields on the exhaust system. The heat of 
the exhaust system or the engine could cause them to ignite! This is a fire 
hazard.Cleaning 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.
Good corrosion protection is particularly important in winter when the car is 
frequently driven on salted roads. To  prevent the salt corroding the vehicle, 
the entire engine compartment should  be thoroughly cleaned before and 
after the salting period.
Your Authorised Service Centre  is able to provide the correct cleaning and 
preserving products and has the necessary equipment. 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 remo
ving solutions, or if you have the engine cleaned. 
If this job is carried out, you should ensure that all surfaces, seams, joints and 
components in the engine compartmen t are given anti-corrosion treatment 
afterwards.
WARNING
•
When working in the engine compartm ent, always observe the safety 
warnings  ⇒page 180.
•
Switch off the engine, apply the parking brake firmly and always 
remove the key from the ignition before you open the bonnet.
•
Allow the engine to cool before you clean the engine compartment.
•
Do not clean the underside of vehicle, wheel arches without protecting 
your hands and arms. You may cut your self 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. If possible, avoid sudden braking immediately after washing 
the vehicle.
•
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 suit-
able filling station.

this reason we recommend that you have service fluids and consumables 
replaced by an Authorised Service Centre. Please observe the relevant 
instructions 
⇒page 172. The engine compartment of any motor vehicle is a 
hazardous area  ⇒.
WARNING
All work on the engine or in the engine compartment, e.g. checking and 
refilling fluids, involves the danger of injury and scalding as well as the risk 
of accident or fire.•
Never open the bonnet if you see steam, smoke or coolant escaping 
from the engine compartment. Otherwis e, there is a risk of sustaining 
burns. Wait until no more steam or  coolant is emitted, then allow the 
engine to cool before carefully opening the bonnet.
•
Switch off the engine and remove the key from the ignition.
•
Apply the handbrake and move the gear stick to neutral or selector 
lever to position P.
•
Keep children away from the vehicle.
•
Never touch hot engine parts. There is a risk of burns.
•
Never spill liquids on a hot engine or on a hot exhaust gas system. This 
is a fire hazard.
•
Avoid causing short-circuits in the electrical system, particularly at the 
points where the jump leads are attached  ⇒page 231. The battery could 
explode.
•
Never touch the radiator fan. It is temperature controlled and could 
start automatically, even when the engine has been switched off and the 
key removed from the ignition!
•
Do not unscrew the cap on the expansion tank when the engine is hot. 
If the coolant is hot, the cooling system will be pressurised!
•
Protect face, hands and arms by covering the cap with a large, thick 
cloth to protect against escaping coolant and steam.
•
Always make sure you have not left any objects, such as cleaning cloths 
and tools, in the engine compartment.
•
If you have to work underneath the vehicle, you must use suitable 
stands additionally to support the vehicle, there is a risk of accident!. A 
hydraulic jack is insufficient for securi ng the vehicle and there is a risk of 
injury.
•
If any work has to be performed when the engine is started or with the 
engine running, there is an additional, potentially fatal, safety risk from the 
rotating parts, such as the drive belts, alternator, radiator fan, etc., and 
from the high-voltage ignition system. You should also observe the 
following points:
−Never touch the electrical wiring of the ignition system.
− Ensure that jewellery, loose cl othing and long hair do not get 
trapped in rotating engine parts. Danger of death. Before starting any 
work remove jewellery, tie back and  cover hair, and wear tight-fitting 
clothes.
− Always think carefully about pressing the accelerator if a gear is 
engaged in either an automatic or manual gearbox. The vehicle could 
move, even if the handbrake is applied. Danger of death.
•
If work has to be carried out on the fuel system or on electrical compo-
nents, you must observe the following sa fety notes in addition to the above 
warnings:
−Always disconnect the battery. The vehicle must be unlocked when 
this is done, otherwise the alarm will be triggered.
− Do not smoke.
− Never work near naked flames.
− Always have a fire extinguisher on hand.WARNING (continued)
