Closing the bonnet
– Lift the bonnet slightly and unhook the bonnet support. Press the bonnet support into the hold er designed to hold it.
– Allow the bonnet to drop from a height of about 30 cm into the lock - bonnet do not press down on it !
WARNING
•Never open the bonnet if you see that steam or coolant is flowing out of
the engine compartment - risk of scaldi ng! Wait long enough until the steam
or coolant has stopped escaping.
•For safety reasons, the bonnet must always be properly closed when
driving. One should therefore check that the lock has in fact engaged prop-
erly after closing the bonnet.
•Stop your vehicle i mmediately while driving if yo u notice that the lock is
not properly engaged and close the bonn et properly - risk of an accident!
Caution
Never open the bonnet using the handle - danger of causing damage.
Working in the engine compartment
Particular care is required when carrying out any work in the engine
compartment!
There is a risk of injuries, scalding, accidents and fire when working in the
engine compartment, e.g. inspecting an d replenishing oil and other fluids. For
this reason, it is essential to comply with the warning instructions stated below and with the general applicable rules of safety. The engine compart-
ment of your car is a hazardous area
⇒ .
WARNING
•Never open the bonnet if you see that steam or coolant is flowing out of
the engine compartment - risk of scaldi ng! Wait long enough until the steam
or coolant has stopped escaping.
•Switch off the engine and pull out the ignition key.
•Apply the handbrake firmly.
•If your vehicle is fitted with a manual gearbox, move the gearshift lever
into Neutral, or if it is fitted with automatic gearbox, move the selector lever
into position P.
•Allow the engine to cool down.
•Keep children clear of the engine compartment.
•Never spill oil and other fluids over the hot engine. Such fluids (e.g. the
antifreeze contained in the coolant) may ignite!
•Avoid short circuits in the electrical system - particularly on the battery.
•Never place your hand into the radiator fan as long as the engine is still
warm. The fan might suddenly start running!
•Never open the cap of the coolant expa nsion bottle as long as the engine
is still warm. The cooling system is pressurized!
•Cover over the cap of the coolant expansion reservoir with a large cloth
when opening it as protection for your face, hands and arms from hot steam
or hot coolant.
•Do not let objects, such as e.g cleaning cloth or tools lie in the engine
compartment.
•If you wish to work under the vehicl e, you must secure the vehicle from
rolling away and support it with suitable supporting blocks: the car jack is
not sufficient for this - risk of injury!
•In cases where it be necessary to carry out inspection work when the
engine is running there is an additional risk from rotating parts (e.g. the V-
ribbed belt, alternator, radiator fan) and from the high-voltage ignition
system. Please observe in addition the following:

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
prescribed distance from your vehicl e while observing all national legal
provisions. 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 th e 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 235 or the caps ⇒page 235.
– In the case of light alloy wheels remove the wheel trim cap ⇒page 236.
– Slacken the wheel bolts ⇒page 236.
– Jack up the vehicle until the wheel to be changed is clear of the ground
⇒ page 237.
– 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, al
ternately and diagonally using the
wheel wrench ⇒page 236.
– Mount the full wheel trim/w heel 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 223.
Subsequent steps
After changing the wheel, you must perform the following steps.
– Stow and attach the replaced wheel in the spare wheel well.
– 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 tight-
ened to a tightening torque of 120 Nm.
– Have the defective tyre repaired as soon as possible.
WARNING
It is necessary to observe the guidelines given on ⇒page 225, “New tyres
and wheels” if the vehicle is subseq uently 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 mu st 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.
Full wheel trim*
Pulling off
– Hook the clamp found in the vehicle tool kit into the reinforced edge of the full wheel trim.
– Push the wheel key through the clamp, support the wheel key on the tyre and pull off the wheel trim ⇒fig. 211 .
Installing
– First press the full wheel trim onto the wheel at the valve opening provided. Then press the full wheel trim into the wheel in such a way
that its entire circumference locks correctly in place. Caution
•Use the pressure of your hand, do not knock on the full wheel trim! Heavy
knocks mainly on the points where the full wheel trim has not been inserted into
the wheel, can result in damage to the guide and centering elements of the full
wheel trim.
•First check for yourself that the theft-deterrent wheel bolt is located
⇒ page 237, “Securing wheels against being stolen*” in the hole in the area of the
valve before fitting the full wheel trim on to a steel wheel which is attached with a

Raise vehicle
You have to raise the vehicle with a lifting jack in order to be able to
take off the wheel.
Position the lifting jack by selecting the jacking point which is closest to
the wheel to be removed ⇒fig. 215 . The jacking point is located directly
below the engraving in the lower sill. The engraving is only visible after
opening the door.
– Position the lifting jack below the jacking point and move it up until its claw is positioned directly below the vertical web of the lower sill.
– Align the car jack so that its claw grasps the web of the lower sill and the base plate is resting flat on the floor.
– Turn the lifting jack up further until the wheel is just clear of the ground.
Ground below the lifting jack which is soft and slippery can cause the vehicle to
slip off the jack. It is therefore always ne cessary to place the lifting jack on a solid
surface or use a wide and stable base. Use a non-slip base (e.g. a rubber foot mat)
if the surface is smooth, such as cobbled stones, a tiled floor, etc.
WARNING
•Always raise the vehicle with the doors closed - risk of injury!
•Take suitable measures to prevent the base of the lifting jack from slip-
ping off - risk of injury!
•Not positioning the lifting jack at the specified points can result in
damage to the vehicle. The jack can also sl ip off if it does not have sufficient
grip - risk of injury!
•It is important to support the vehicle with suitable supporting blocks if
you wish to work under the lifted vehicle - risk of injury!
Securing wheels against being stolen*
You need a special adapter for slackening the safety wheel bolts.
– Pull off the full wheel trim/cap from the wheel hub or cap from the safety wheel bolt.
– Insert the adapter with its toothed side fully into the inner toothing of the safety wheel bolt right down in such a way that only the
outer hexagon is jutting out ⇒fig. 216 .
– Insert the wheel wrench fully onto the adapter .
– Slacken the wheel bolt, or tighten it firmly ⇒page 236.
