Care of the vehicle exteriorAutomatic car washing tunnelThe vehicle paintwork is so durable that the vehicle can normally be washed
without problems in an automatic car wash tunnel. However, the paintwork
wear depends to a large extent on the kind of the car wash tunnel, the
brushes used, its water filtering and the type of cleaning and preservative
products.
Before going through a car wash, be sure to take the usual precautions such
as closing the windows and sunroof. There is nothing to note apart from that.
If the vehicle has special accessories such as spoilers or a roof rack or two-
way radio aerial, etc., it is advisable to consult the car wash tunnel operator.
After washing, the brakes could take some time to respond as the brake discs
and pads could be wet, or even frozen in winter. Dry the brakes by braking
several times.
WARNING
Water, ice and salt on the brakes can reduce braking efficiency. Risk of acci-
dent.
Caution
Before putting the vehicle through the car washing tunnel, do not tighten the
aerial if it is folded because it can be damaged.
Washing by handVehicle washing
– First soften the dirt and rinse it off with water.
– Clean your vehicle from top to bottom with a soft sponge, a glove or a brush. Use very light pressure.
– Rinse the sponge or glove often with clean water.
– Special car shampoo should only be used for very stubborn dirt.
– Leave the wheels, sill panels etc. until last, using a different sponge or glove.
– Rinse the vehicle thoroughly with water.
– Dry the vehicle surface gently with a chamois leather.
–In cold temperature , dry the rubber seals and their surfaces to
prevent them from freezing. Apply silicone spray to the rubber
seals.
After washing the vehicle
– After washing, avoid sudden and sharp braking. Dry the brakes by braking several times.
WARNING
•Wash your vehicle with the ignition switched off.•Protect your hands and arms from cuts on sharp metal edges when
cleaning the underbody, the inside of the wheel housings etc. Risk of
injury.

Vehicle maintenance and cleaning
178Underbody protection
The vehicle underbody is coated to protect it from chemical
and mechanical damage.The protective coating can be damaged when driving. We recommend you to
check the protective coating under the body and on the running gear, and
reinstated if necessary, before and after the winter season.
We recommend you to go to your Authorised Service Centre to carry out repair
work and additional anti-corrosion work.
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. Risk of fire.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.
G o o d co r r o s i o n p r o t e c t i o n is p a r t i cu la r l y i m p o r t a n t i n wi n te r w h e n t h e v e h i c le
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 188.•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 only be carried out at a specialised workshop or an
adequate petrol station.

− Insert the fuel nozzle into the mouth of the canister as far as
possible.
− If the spare fuel canister is made of metal, the filling nozzle must be
in contact with the canister during filling. This helps prevent an electro-
static charge building up.
− Never spill fuel in the vehicle or in the luggage compartment. Fuel
vapours are explosive. Danger of death.Caution
•Fuel spills should be removed from the paintwork immediately.•Never run the tank completely dry. An irregular fuel supply could cause
misfiring. As a result, unburnt fuel could enter the catalytic converter and
cause damage.•When filling the fuel tank after having run it completely dry on a vehicle
with a diesel engine the ignition must be switched on for at least 30 seconds
without starting the engine. When you then start the engine it may take
longer than normal (up to one minute) for the engine to start firing. This is due
to the fact that the fuel system has to purge itself of air before starting.For the sake of the environment
Do not try to put in more fuel after the automatic filler nozzle has switched off;
this may cause the fuel to overflow if it becomes warm.
PetrolPetrol types
The correct petrol types are listed on a sticker inside the fuel
tank flap.Only unleaded petrol conforming to standard DIN EN 228 may be used for
vehicles with catalytic converters (EN = “European Standard”).
Fuel types are differentiated by the octane rating, e.g: 91, 95, 98 RON (RON
= “Research Octane Number”, unit for determining the knock resistance of
petrol). You may use petrol with a higher octane number than the one recom-
mended for your engine. However, this has no advantage in terms of fuel
consumption and engine power.
Caution
•Even one tankful of leaded fuel would permanently impair the efficiency
of the catalytic converter.•High engine speed and full throttle can damage the engine when using
petrol with an octane rating lower than the correct grade for the engine.For the sake of the environment
Just one full tank of leaded fuel would seriously impair the efficiency of the
catalytic converter.

Petrol additives
Petrol additives improve the quality of the petrol.The quality of the petrol influences the performance, power and life of the
engine. For this reason, you should use good quality petrol containing addi-
tives. These additives will help to prevent corrosion, keep the fuel system
clean and prevent deposits from building up in the engine.
If good quality petrol with additives is not available or engine problems occur,
the required additives must be added during refuelling.DieselDiesel*Diesel fuel must conform to DIN EN 590 (EN = “European Standard”). It must
have a cetane number (CN) of at least 51. The cetane number indicates the
ignition quality of the diesel fuel.
Notes on refuelling ⇒ page 185.Biodiesel*
Caution
•Your vehicle is not designed to use biodiesel fuel. Never, under any
circumstances refuel with biodiesel. The use of biodiesel fuel could damage
the engine and the fuel system. The addition of biodiesel to diesel fuel by the
diesel manufacturer in accordance with standard EN 590 or DIN 51628 is
authorised and will not cause damage to the engine or the fuel system.
•The diesel engine has been designed to be used exclusively with diesel
fuel conforming to standard EN 590. Never refuel or use petrol, kerosene, fuel
oil or any other type of fuel. If you accidentally fill up the vehicle with the
wrong type of fuel, do not start the engine. Seek assistance from specialised
personnel. The composition of these fuels may severely damage the fuel
system and the engine.Winter driving
Diesel can thicken in winter.Winter diesel
When using summer diesel fuel, difficulties may be experienced at tempera-
tures below 0 °C because the fuel thickens due to wax separation. Therefore,
winter diesel fuel is available in some countries during the cold months. It can
be used at temperatures as low as -22 °C.
In countries with different climatic conditions the diesel fuel generally sold
has different temperature characteristics. Check with an Authorised Service
Centre or filling stations in the country concerned regarding the type of diesel
fuels available.
Filter pre-heater
Your vehicle is fitted with a fuel filter glow plug system, making it well
equipped for operation in winter. This ensures that the fuel system remains
operational to approx. -24 °C, provided you use winter diesel which is safe to
-15 °C.
However, if the fuel has waxed to such an extent that the engine will not start
at temperatures of under -24 °C, simply place the vehicle in a warm place for
a while.
Caution
Do not mix fuel additives (thinners or similar products) with diesel fuel.
