Automatic vehicle wash systems
The paintwork of the vehicle is sufficiently resistant that the vehicle can be wash-
ed normally in automatic vehicle wash plants without any problem. The actual
stress to which the paintwork is subjected, however, depends greatly on the de-
sign of the vehicle wash system, the filtering of the water and the type of wash-
ing and care products used. If the paintwork of your vehicle appears mat after be-
ing washed or even has scratches, point this out to the operator of the vehicle
wash plant. Use a different vehicle wash plant, if necessary.
There are no particular points to note before washing your vehicle in an automatic
vehicle wash system other than the usual precautionary measures (closing the
windows including the sliding/tilting roof, removing the external antenna, etc.).
If you have any particular attached parts fitted to your car - such as spoiler, roof
rack system, two-way radio aerial - it is best to first of all consult the operator of
the car wash plant.
It is important to degrease the lips of the windscreen wiper rubbers after passing
through the automatic vehicle wash system.
Washing vehicle by hand It is important to first soften the dirt with plenty of water and rinse it off as thor-
oughly as possible before washing your vehicle by hand.
One should then clean the vehicle using a soft
washing sponge, washing glove or
a washing brush and only slight pressure. Work from the top to the bottom - be-
ginning with the roof. Only place slight pressure on the vehicle paintwork during
cleaning Only use a car shampoo for stubborn dirt.
Wash out the sponge or washing glove thoroughly at short intervals.
Clean wheels, door sills and similar parts last. Use a second sponge for such areas.
Rinse off the vehicle well after giving it a wash and dry it off using a chamois
leather. WARNING
● The ignition should always be switched off when you wash your vehicle -
risk of accident!
● Protect your hands and arms from sharp-edged metal parts when you are
cleaning the underfloor, the inside of the wheel housings or the wheel trims -
risk of cuts. CAUTION
● Do not wash your vehicle in bright sunlight - risk of paint damage.
● Ensure that the jet of water is not aimed directly at the locking cylinders or at
the door and panel joints if you spray your vehicle in winter down with a hose -
risk of freezing.
● Do not use any insect sponges, rough kitchen sponges or similar cleaning
products - risk of damage to the surface of paintwork. For the sake of the environment
Only wash your vehicle at washing bays specifically reserved for this purpose. This
ensures that no water which may be contaminated by oil flows into the sewage
system. It is not even permitted to wash your vehicle in certain areas except at
such specific washing bays.
Washing with a high-pressure cleaner When you wash your vehicle with a high-pressure cleaner, it is essential to comply
with the instructions for use of the cleaning equipment. This applies in particular
to the pressure
used and to the spraying distance. Maintain a sufficiently large
distance to soft materials such as rubber hoses or insulation material.
On no account use circular spray nozzles or so-called dirt cutters! WARNING
It is particularly important that you do not clean tyres with circular spray jets.
Visible but also invisible damage to tyres may occur even at a relatively large
spraying distance and if sprayed only for a short time - risk of accident! CAUTION
The wash water must be no hotter than 60 °C, otherwise the vehicle can be dam-
aged.
Wax treatment Good wax treatment is an effective way of protecting the paintwork from harmful
environmental influences and minor mechanical damage.
The vehicle must be treated with a high-quality hard wax polish at the latest,
when no more drops form on the clean paintwork. £ 181

Open the bonnet ⇒ page 189 .
– Check the level of coolant in the coolant expansion bottle ⇒ fig. 155. When the
engine is cold, the coolant level must lie between the a and
b markings. The
level may also rise slightly above the a (MAX) marking when the engine is
warm.
If the coolant level in the reservoir is too low, this is indicated by the warning light
in the instrument cluster ⇒ page 26
, Coolant temperature/Coolant quantity . We
still recommend inspecting the coolant level directly at the reservoir from time to
time.
Loss of coolant
A loss of coolant is first and foremost an indication of a leak in the system. You
should not merely top up the coolant in the reservoir. It is also important to have
the cooling system inspected without delay by a specialist garage.
Losses can only occur through the pressure relief in the cap of the coolant expan-
sion bottle which is completely free of leaks if the coolant boils as a result of over-
heating and is forced out of the cooling system. WARNING
Read and observe the warning notes ⇒ page 190
, Working in the engine com-
partment before working in the engine compartment. CAUTION
One should contact a specialist garage as soon as possible if the source of over-
heating itself cannot be determined and removed, since there may be grave dam-
age to the engine.
Replenishing the coolant –
Switch the engine off.
– Allow the engine to cool down.
– Place a cloth over the cap of the coolant expansion reservoir ⇒
fig. 155 and un-
screw the cap carefully by turning it to the left ⇒ .
– Top up the coolant.
– Screw the cap tight until it is heard to lock. The coolant which you use for replenishing the system, must comply with one
specific specification ⇒ page 193. Do not use an alternative additive if the speci-
fied coolant additive is not available in exceptional cases. Just top up the system
with water and as soon as possible arrange adjustment to correct the mixing ratio
of water and coolant additive again by a specialist garage.
Only use fresh coolant for topping up the system.
Do not fill the coolant above the mark a (max.)
⇒ fig. 155 ! Excess coolant heats up
and then is forced out of the cooling system through the pressure relief valve in
the cap.
Wait until the engine has cooled down for a system which has suffered a major
loss of coolant before pouring in coolant. This is necessary to avoid engine dam-
age. WARNING
● The cooling system is pressurized! Do not open the cap of the coolant ex-
pansion bottle if the engine is still hot - risk of scalding!
● The coolant additive and thus all of the coolant is harmful to your health.
Avoid contact with the coolant. Coolant vapours are also harmful to the
health. It is important, therefore, to always safely store any coolant additive in
its original container out of the reach of children - risk of poisoning!
● If any splashes of coolant get into your eyes, rinse out your eyes immedi-
ately with clear water and contact a doctor as soon as possible.
● You should also consult a doctor without delay if you have inadvertently
swallowed coolant. CAUTION
Do not continue your journey if for some reason it is not possible under the con-
ditions prevailing to top up with coolant. Switch the engine off and obtain pro-
fessional assistance from a specialist garage, otherwise it could lead to severe en-
gine damage. For the sake of the environment
Do not re-use coolant if it is necessary to drain the coolant in the system. It should
be collected and disposed of in compliance with environmental protection regula-
tions. 194
Inspecting and Replenishing
Wheels and Tyres
Wheels
General information ●
New tyres do not offer optimal grip at first. They should therefore be run in for
about 500 km at a moderate speed and an appropriately cautious style of driving.
You will also profit from longer tyre life.
● The tread depth of new tyres may differ because of design features and the
configuration of the tread (depending on the type of tyre and the manufacturer).
● Drive over curbs on the side of the road and other such obstacles slowly and,
where possible, at a right angle in order to avoid damage to tyres and wheel trims.
● We recommend you Inspect your tyres and rims from time to time for damage
(punctures, cuts, splits and bulges). Remove foreign bodies from the tyre profile.
● Damage to tyres is frequently not visible. Unusual vibrations or pulling of the
vehicle to one side could be a sign of tyre damage. Please reduce your speed im-
mediately and stop if you suspect that a wheel is damaged. Inspect the tyres for
signs of damage (bulges, splits, etc.) If no visible damage is present, please drive
at an appropriately slow speed and carefully to the nearest specialist garage in or-
der to have your vehicle inspected.
● Also protect your tyres from contact with oil, grease and fuel.
● Immediately replace any dust caps of the valves which have got lost.
● Mark wheels before removing them so that their previous direction of running
can be maintained when mounted them again.
● Always store wheels or tyres which been removed in a cool, dry and, where
possible, dark place. Tyres which are not fixed to a wheel trim should be stored
upright.
Unidirectional tyres
The direction of rotation of the tyres is marked by arrows on the wall of the tyre.
This indicates the direction of rotation of the tyre, and it is essential that the tyres
are fitted on to run in this direction. Only then are the tyres able to provide the
optimal properties in terms of grip, low noise, wear-and-tear and aquaplaning.
Further information concerning the use of unidirectional tyres ⇒
page 205. WARNING
● New tyres during the first approximately 500 km do not offer optimal grip
and should therefore be run appropriately - risk of accident!
● Never drive with damaged tyres - risk of accident! Note
Please observe the various differing legal requirements regarding tyres.
Tyre life Fig. 160 An opened fuel filler flap with a
tyre size and tyre inflation pressure ta-
ble
The life of your tyres very much depends on the following points:
Tyre pressure
The working life of tyres will be shortened considerably if the tyres are insuffi-
ciently or over-inflated and this will have an adverse effect on the handling of
your vehicle.
Correctly inflated tyres are of particular importance when travelling at high
speeds . It is therefore good to check the tyre pressure, including that of the spare
wheel, at least once a month and also before setting off on a long trip.
The tyre inflation pressures for summer tyres are indicated on the inside of the
fuel filler flap ⇒ fig. 160 . The inflation pressures for winter tyres are 20 kPa
(0.2
bar) higher than those for summer tyres ⇒ page 204. £ 201

WARNING
● If you find yourself in flowing traffic switch on the hazard warning lights
system and place the warning triangle on the side of the road at the prescri-
bed distance from your vehicle. Comply with the national legal regulations. In
this way you are protecting not only yourself but also other road users.
● Never start the engine with the vehicle sitting on the raised jack - danger
of suffering injury. CAUTION
If you have to change a wheel on a slope first block the opposite wheel with a
stone or similar object in order to secure the vehicle from unexpectedly rolling
away. Note
Comply with the national legal regulations.
Changing a wheel Always change a wheel on a level surface as far as possible.
–
Take off the full wheel trim ⇒ page 210 or the wheel trim cap ⇒ page 211 or
the caps ⇒ page 211.
– In the case of light alloy wheels remove the wheel trim cap ⇒
page 211.
– First of all slacken the safety wheel bolt and afterwards the other wheel bolts
⇒ page 211.
– Jack up the vehicle until the wheel to be changed is clear of the ground
⇒ page 212.
– Unscrew the wheel bolts and place them on a clean surface (cloth, paper etc.).
– Take off the wheel.
– Fit on the spare wheel and tighten the wheel bolts slightly.
– Lower the car.
– Tighten the wheel bolts firmly, alternately and diagonally using the wheel
wrench (crosswise) and lastly the wheel safety bolt ⇒
page 211.
– Mount the full wheel trim/wheel trim cap or the caps. Note
● All bolts must be clean and must turn easily.
● You must never grease or oil the wheel bolts!
● When fitting on unidirectional tyres, ensure that the tyres rotate in the correct
direction ⇒ page 201
.
Subsequent steps After changing the wheel, you must perform the following steps.
–
Stow and attach the replaced wheel in the spare wheel well using a special
screw ⇒ fig. 165 .
– Stow the vehicle tool kit in the space provided.
– Check the tyre pressure on the spare wheel just mounted as soon as possible.
– Have the tightening torque of the wheel bolts checked with a torque wrench
as soon as possible. Steel and light alloy wheels must be tightened to a tight-
ening torque of 120
Nm.
– Change the damaged wheel or consult a specialist garage about possibilities
for getting repairs done. WARNING
It is necessary to observe the guidelines given on ⇒
page 203 if the vehicle is
subsequently fitted with tyres which are different to those it was fitted with
at the works. Note
● If you find, when changing the wheel, that the wheel bolts are corroded and
difficult to turn, the bolts must be replaced before checking the tightening torque.
● Drive cautiously and only at a moderate speed to a workshop where the tight-
ening torque can be checked.
