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!

Engine oilCheck engine oil level
The dipstick indicates the le vel of oil in the engine.Checking the oil level– Ensure that the vehicle is po sitioned on a level surface.
– Switch the engine off.
– Open the bonnet in “Working in the engine compartment” on page 197.
– Wait a few minutes and pull out the oil dipstick.
– Wipe off the dipstick with a clea n cloth and insert it again fully.
– Then withdraw the dipstick again and read off the oil level.Oil level within range –You must not top up the oil.Oil level within range –You may top up the oil. It is possible that the oil level may then be within range
after doing this.Oil level within range –You must top up the oil page 199. It is sufficient, once this is done, to keep the
oil level within range .

Note
On vehicles which are fitted with an indepe ndent auxiliary heating and ventilation, the
volume of the coolant is greater by approx. 1 ltr.Inspecting the coolant levelThe coolant expansion bottle is located in the engine compartment on the right.
– Switch the engine off.
– Open the bonnet page 196.
– Check the level of coolant in the coolant expansion bottle fig. 164 . The coolant
level when the engine is cold must lie between the (MIN) and (MAX) mark-
ings. The level may also rise slightly above the (MAX) marking when the engine
is warm.
If the coolant level in the reservoir is too lo w, this is indicated by the warning light in
the instrument cluster page 31, “Coolant temperature/coolant level ”. We never-
theless recommend inspecting the coolant leve l 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 expansion
bottle which is completely free of leaks if the coolant boils as a result of overheating
and is forced out of the cooling system.
WARNING
Read and observe the warning notes page 197, “Working in the engine
compartment” before working in the engine compartment.
Caution
One should contact a specialist garage as s oon as possible if the source of overheating
itself cannot be determined and removed, since there may be grave damage 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. 164 and
unscrew 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 th e system, must comply with one specific
specification page 200. Do not use an alternative additive if the coolant additive
G13 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 addi-
tive again by a specialist garage.
Only use fresh coolant for topping up the system.
Do not fill up over the “MAX” marking! Excess coolant which is heated up is forced out
of the cooling system through the pressure relief valve in the cap of the coolant
compensation bottle.
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 damage.

202WARNING
The cooling system is pressurized! Do not open the cap of the coolant
expansion 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 orig-
inal container out of the reach of children - risk of poisoning!
If any splashes of coolant get into yo ur 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
conditions prevailing to top up with coolant. Switch the engine off and obtain
professional assistance from a specialist garage, otherwise it could lead to severe
engine 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 regulations.Radiator fan
The radiator fan may switch on suddenly.The radiator fan is driven by an electric motor and controlled according to the coolant
temperature.
The radiator fan may continue running for up to 10 minutes after the engine has been
switched off - even if the ignition is also off. It may also switch on suddenly after a
certain time, if
the coolant temperature has risen beca use of an accumulation of heat or
the warm engine compartment is heated up additionally by strong sunlight.
WARNING
You must therefore be aware when working in the engine compartment that the
fan may switch on suddenly - risk of injury!Brake fluidInspecting the brake fluid levelThe brake fluid reservoir is located on the left of the engine compartment. The brake
fluid reservoir on right-hand steering models is positioned on the other side of the
engine compartment.
– Switch the engine off.
– Open the bonnet page 196.
– Inspect the brake fluid level in the reservoir fig. 165 . The level must be between
the “MIN” and “MAX” markings.
A slight drop in the fluid level results when driving due to normal wear-and-tear and
automatic adjustment of the brak e pads, and is perfectly normal.
There may be an indication of a leak in th e brake system, however, if the fluid level
drops significantly within a short time or if it drops below the “MIN” marking. If the
brake fluid level is too low, this is indicated by the warning light page 34, “Brake
system ” lighting up in the instru ment cluster. In this case stop immediately and do
not drive any further! Obtain professional assistance.
