Vehicle maintenance and cleaning
General notes
Regular washing and care help maintain the value of your
vehicle.Vehicle maintenance
Regular care and washing help to maintain the value of the vehicle. This
may also be one of the requirements for acknowledging warranty claims in
the event of bodywork corrosion or paint defects.
The best way to protect your vehicle against the harmful effects of the envi-
ronment is through correct maintenance and frequent washing. The longer
substances such as insect remains, bird droppings, resinous tree sap, road
dirt, industrial deposits, tar, soot or road salt and other aggressive materi-
als remain on the vehicle, the more damage they do to the paintwork. High
temperatures (for instance in strong sunlight) further intensify the corrosive
effect.
After winter, a period when salt is put on the roads, it is important to have
the underside of the vehicle washed thoroughly.
Products for vehicle maintenance
Car care products are available in your Technical Services. Keep the product
instructions until you have used them up.
WARNING
● Car care products can be toxic. Because of this, they must always be
kept closed in their original container. Keep them out of the reach of chil-
dren. Failure to comply could result in poisoning.
● Always read and observe the instructions and warnings on the pack-
age before using vehicle care products. Improper use could cause health
problems or damage the vehicle. The use of certain products may pro-
duce noxious vapours; they should be used in well ventilated areas.
● Never use fuel, turpentine, engine oil, nail varnish remover or other
volatile fluids. These are toxic and highly flammable. Risk of fire and ex-
plosion.
● Before washing your vehicle, or carrying out any maintenance, switch
the engine off, apply the handbrake firmly and remove the key from the
ignition.
CAUTION
Never attempt to remove dirt, mud or dust if the surface of the vehicle is dry.
Never use a dry cloth or sponge for cleaning purposes. This could damage
the paintwork or the windows of your vehicle. Soak dirt, mud or dust with
plenty of water.
For the sake of the environment
● When purchasing products for your vehicle maintenance, select the
ones which are not harmful to the environment.
● The waste from car care products should not be disposed of with ordina-
ry household waste. Observe the disposal information on the package. 

234Checking and refilling levels
Opening the bonnet
Fig. 179 Release catch
under the bonnet
Before opening the bonnet make sure that the windscreen wiper
arms are not lifted away from the glass. Otherwise the paint may
be damaged.
– Lift the bonnet slightly ⇒ 
.
– Press the release catch under the bonnet upwards ⇒ Fig. 179.
This will release the arrester hook under the bonnet.
– Open the bonnet.
The bonnet is held in position by a gas-filled strut.
WARNING
Never open the bonnet if you see steam or drips of coolant being re-
leased from the engine compartment. Failure to comply could result in
burns. Wait until no steam or coolant can be seen before opening the
bonnet.
 Work in the engine compartment
Extra caution is necessary when working on components in
the engine compartment.
Always be aware of the danger of injury and scalding as well as the risk of
accident or even fire when working in the engine compartment (e.g. when
checking and refilling fluids). Always observe the warnings listed below
and follow all general safety precautions. The engine compartment of the
vehicle is a potentially hazardous area ⇒ 
WARNING
● Switch the engine off.
● Remove the ignition key.
● Apply the handbrake firmly.
● If your vehicle is equipped with a manual gearbox, place the gear lev-
er in neutral. If you are driving an automatic vehicle, place the selector
lever in position P.
● Wait for the engine to cool down.
● Children should not be allowed to approach the engine compartment.
● Never spill liquids used for vehicle operation on the engine compart-
ment, as these may catch fire (e.g. coolant).
● Take care not to cause short circuits in the electrical system, especial-
ly when working on the battery.
● 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 ex-
pansion tank. 

262If and when
Changing a wheel
Preparation work
What you must do before changing a wheel.
– If you have a flat tyre or puncture, park the vehicle as far away
from the flow of traffic as possible. Choose a location that is as
level as possible.
– All passengers should leave the vehicle. They should wait in a
safe place (e.g. behind the roadside crash barrier).
– Apply the handbrake firmly.
– Engage first gear .
– When towing a trailer: Unhitch the trailer from your vehicle.
– Take the tools and the spare wheel ⇒  page 259 out of the lug-
gage compartment.
WARNING
If you have a puncture in heavy traffic, switch on the hazard warning
lights and place the warning triangle in a visible location. This is for your
own safety and also warns other road users.
CAUTION
If you have to change the tyre on a gradient, block the wheel opposite the
wheel being changed by placing a stone or similar object under it to prevent
the vehicle from rolling away.
Note
Please observe legal requirements when doing so. 
Changing a wheel
Change the wheel as described below.
– Remove the wheel cover .
– Loosen the wheel bolts ⇒ page 263.
– Raise the vehicle with the jack ⇒ page 264.
– Take off the wheel with the flat tyre and then put on the spare
wheel ⇒ page 265.
– Lower the vehicle.
– Tighten the wheel bolts firmly in diagonal sequence with the
box spanner ⇒ page 263.
– Replace the cover. 
After changing a wheel
After changing the wheel, there are still tasks to complete. – Place the wheel with the defective tyre in the spare wheel well
and secure it.
– Put the tools and jack back in the luggage compartment. 

268If and when
Repairing a tyre
Fig. 201 Repairing a tyre
Preparations
– If you have a flat tyre or puncture, park the vehicle as far away
from the flow of traffic as possible.
– Apply the handbrake firmly to prevent the vehicle from moving
accidentally on slopes.
– Engage first gear .
– Check whether a repair is possible using the Tyre Mobility Sys-
tem ⇒ page 266.
– Ensure that all passengers leave the vehicle and move away
from the danger area ⇒ 
.
– Take the tyre sealant can and the compressor out of the lug-
gage compartment. –
Stick the “max. 80 km/h” adhesive, which is included with the
tyre sealant can, onto the instrument panel where the driver will
see it.
Filling the tyre
– Shake the tyre sealant can well.
– Screw the enclosed filling hose onto the sealant can as far as it
will go. This will automatically pierce the foil sealing the can.
– Take the valve cap off the tyre valve and use the enclosed valve
insert tool to unscrew the valve insert ⇒ Fig. 201.
– Place the valve insert onto a clean surface.
– Remove the sealing plug from the filling hose and insert the
hose into the tyre valve.
– Hold the tyre sealant can upside down and fill the complete
contents of the can into the tyre.
– Then disconnect the hose and screw the valve insert firmly back
into the tyre valve.
Inflating the tyre
– Screw the compressor filling hose onto the tyre valve and plug
the connector into the cigarette lighter.
– Pump the tyre up to 2.0 to 2.5 bar and monitor the pressure
shown on the pressure gauge.
– If the tyre pressure remains lower than the value specified
above drive the vehicle approx. 10 metres forwards or back-
wards, so that the sealant can spread evenly in the tyre. If the 
