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, acci dents and fire when working in the engine
compartment, e.g. inspecting and 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 safe ty. The engine compartment 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 scalding! 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 anti-
freeze 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 su ddenly start running!
Never open the cap of the coolant expans ion 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 lifting 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 fr om rotating parts (e.g. the V-ribbed belt,
alternator, radiator fan) and from the high-voltage ignition system. Please
observe in addition the following:
Never touch the electrical cabl es of the ignition system.
Absolutely avoid any jewellery, loose it ems of clothing or long hair from
getting into the rotating parts of the engine - Hazard! Therefore remove any
jewellery beforehand, tie up your hair and wear tight fitting clothing.
Please also comply with the warnin g instructions stated below when
carrying out any essential work on the fu el system or on the electrical system:
Always separate the car battery from the electrical system.
Do not smoke.
Never carry out any work close to naked flames.
Always keep a working fire extinguisher at hand.Caution
When replenishing fluids in the engine, always ensure that the fluids are on no account
mixed up. This may result in major oper ating problems and also vehicle damage!

Spare wheel*The spare wheel lies in a well under the floor covering of the luggage compartment and
is fixed in place using special screws fig. 175 .
Before removing the spare wheel, you must take out the box with the vehicle tool kit
box page 216, fig. 174.
One should check the inflation pressure in the spare wheel (at best when generally
checking the tyre air pressures - see sign on the fuel filler flap page 208) to ensure
that the spare wheel is always ready to use.
Temporary spare wheel
A warning label displayed on the rim of the temporary spare wheel indicates that your
vehicle is equippe d with a temporary spare wheel.
Please observe the following notes when driving with a temporary spare wheel:
The warning label must not be covered after installing the wheel.
Do not drive faster than 80 km/h with this spare wheel and pay particular attention
while driving. Avoid accelerating at full throttle, sharp braking and fast cornering.
The inflation pressure for this spare wheel is identical to the inflation pressure of
the standard tyres. The temporary spare wheel R 18 must have an inflation pressure of
420 kPa (4.2 bar)!
Use this spare wheel only to reach the nearest specialist garage as it is not intended
for continuous use.
No other summer or winter tyres must be mounted on the rim of the spare wheel
R 18.
Changing a wheelPreliminary workThe following steps should be carried ou t before actually changing the wheel.
– If it is necessary to change a wheel, park the vehicle as far away as possible from
the traffic flow. The place you choose should be level.
–Have all the occupants get out. While changing a wheel, the occupants of the
vehicle should not stand on the ro ad (e.g. behind a crash barrier).
– Apply the handbrake firmly.
–Engage 1st gear or if your vehicle is fitted with an automatic gearbox, position the
selector lever into position P .
– If a trailer is coupled, uncouple it.
–Take the vehicle tool kit page 216 and the spare wheel* page 217 out of the
luggage compartment.
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 vehicle while observin g 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 si tting on the raised jack - danger of
suffering injury.Caution
If you have to change a wheel on a slope fi rst 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.

Start engineIt is important to connect the jump -start cables in the correct order.Connecting positive terminals– Attach one end to the positive terminal fig. 181 of the discharged battery
.
– Attach the other end to the positive term inal of the battery supplying the power
.Connecting negative terminal and engine block– Attach one end to the negative termin al of the battery supplying the power .
– Attach the other end to a solid metal part which is connected firmly to the
engine block, or to the engine block itself.Starting the engine– Start the engine of the vehicle providing current and run the engine at idling speed.
– Now start the engine of the vehicle with the discharged battery.
– Interrupt the attempt at starting an engine after 10 seconds if it does not start right
away and wait for about 30 seconds before repeating the attempt.
– Disconnect the cables on the engine in exactly the reverse order they were
connected up.
WARNING
The non-insulated parts of the terminal clamps must never make contact
with each other. Furthermore, the cable connected to the positive terminal of
the battery must not come into contact with electrically conducting parts of the
vehicle - risk of a short circuit!
Do not affix the jump starting cables to the negative terminal of the
discharged battery. There is the risk of detonating gas seeping out the battery
being ignited by the strong spark which results from the engine being started.
Run the jump-start cables so that they cannot be caught by any rotating
parts in the engine compartment.
Do not bend over the batteries - risk of caustic burns!
The vent screws of the battery cells must be tightened firmly.
Keep any sources of ignition (naked flame, smouldering cigarettes etc.)
away from the battery - risk of an explosion!
Never jump-start the batteries which ha ve a too low electrolyte level - risk
of explosion and caustic burns!
Tow-starting and towing vehicleGeneralPlease pay attention to the following instru ctions if you are going to use a tow rope:Driver of the towing vehicle– Do not drive off until the tow rope is taught.
– Release the clutch particularly gently wh en starting off or depress the accelerator
particularly gently if yo ur vehicle is fitted with an automatic gearbox.Driver of the towed vehicle– Switch the ignition on so that the steeri ng wheel is not blocked and you can also

– Take the vehicle out of gear or move the selector lever into position
N if your
vehicle is fitted with an automatic gearbox.
– Note that the brake servo unit and power steering only operate if the engine is running. You will require significantly grea ter physical force to depress the brake
pedal and to steer th e vehicle if the engine is not running.
– Ensure that the tow rope is always kept taught.
Tow rope or tow bar
A tow bar is safest way of towing a vehicle an d also minimizes any shocks. You can use
a tow rope only if a suitable tow bar is not available.
The tow rope must be elastic to protect the vehicle. Thus one should only use plastic
fibre rope or a rope made out of a similarly elastic material.
Only attach the tow rope to the towing eyes provided for this purpose page 223
and page 224.
Driving style
Towing another vehicle requires a certain am ount of practice. Both drivers should be
familiar with the particular points about to wing a vehicle. Unskilled drivers should not
attempt to tow in another vehicle or to be towed in.
One should be constantly vigi lant not to allow impermissibly high towing forces or
jerky loadings. There is always a risk of excessive stresses and damage resulting at the
points to which you attach the tow rope or tow bar when you attempt to tow a vehicle
which is not standing on a paved road.
Caution
If the gearbox of your vehicle no longer contains any oil because of a defect, your
vehicle must only be towed in with the driven wheels raised clear of the ground, or on
a special vehicle transporter or trailer.
Note
Please comply with any national legal provisions particularly regarding the
switched on signal systems, when towi ng in or tow-starting another vehicle.
The tow rope must not be twisted as it ma y in certain circumstances result in the
front towing eye being unscrewed out of your vehicle.
Front towing eye
The towing eye is stored in th e box for the vehicle tool kit.Fig. 182 Front bumper: protective gr ille / installing the towing eyeCarefully remove the cover as follows.
– Guide the fingers into the opening fig. 182 .
– By pulling in the direction of arrow , first of all slacken the cover in the upper area on the side to the fog lights.
– Afterwards, also slacken the cover on th e other side in the direction of arrow
and remove it.
– Screw in the towing eye by hand to the left up to the stop fig. 182 - right and
tighten. For tightening, we recommen d that you use for example the wheel
wrench*, the lashing eye of another vehicl e or a similar object which you can push
through the eye.
– In order to reinstall the cover after screwing out the towing eye, first of all insert it
starting on the side facing the marking. Then press the cover closed on the side
facing the fog light. The cover must engage firmly.
