– Allow the bonnet to drop from a height of about 30 cm into the
lock - bonnet do not press down on it!
The bonnet is held in the opened position by a pressurized gas spring.
WARNING
•Never open the bonnet if you see that steam or coolant is
flowing out of the engine compartmen t - risk of scalding! 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 properly after closing the bonnet.
•Stop your vehicle immediately while driving if you notice that
the lock is not properly engaged and close the bonnet properly -
risk of an accident!
Caution
•Never open the bonnet using the handle - danger of causing damage.
•Before opening the bonnet, ensure that the arms of the windscreen
wipers are correctly in place against the windscreen. Otherwise, there is
a risk of damage to the paintwork.
Working in the en gine 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 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 safety. 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 gear-
shift 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.
•Do not touch any hot engine parts - risk of burns!
•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 expansion 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.

out the battery being ignited by the strong spark which results from
the engine being started.
•Do not affix the cable end to parts of the fuel and brake
system.
•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 ciga-
rettes etc.) away from the battery - risk of an explosion!
Tow-starting and towing vehicle
General
Please pay attention to the following instructions 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 when starting off or depress the accelerator particularly gently if your vehicle is
fitted with an automatic gearbox. Driver of the towed vehicle
– Switch the ignition on so that the steering wheel is not blocked
and you can also operate the turn signal lights, the headlight
flasher, the windscreen wipers and windscreen washer
system.
– 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 greater
physical force to depress the brake pedal and to steer the
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 and 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.
Attach the tow rope or the tow bar only to the towing eyes provided for
this purpose ⇒page 258, “Front towing eye” and ⇒page 258, “Rear
towing eye”.
Driving style
Towing another vehicle requires a certain amount of practice. Both drivers
should be familiar with the particular points about towing a vehicle.
Unskilled drivers should not attempt to tow in another vehicle or to be
towed in.
One should be constantly vigilant not to allow impermissibly high towing
forces or jerky loadings. There is always a risk of excessive stresses and

Fuses and light bulbs
262
The power windows and the power seats are protected by automatic
circuit breakers which switch on again automatically after a few seconds
after the overload has been eliminated - e.g. frozen windows.
Bulbs
Changing bulbs
The relevant lamp must always be switched off before a light bulb is
replaced.
Do not take hold of the glass bulb with naked fingers (even the smallest
amount of dirt reduces the working life of the light bulb). Use a clean cloth,
serviette or something similar.
Defect light bulbs should only be replaced with light bulbs of the same
type. The designation is located on the light socket or the glass bulb.
Changing certain bulbs is not something which you can do yourself, but
requires to be done by a specialist. Other parts of the vehicle must be
