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 replen ishing 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.
•
Move the gear lever into the Neutral position.
•
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 suddenly 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 expans ion 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. cle aning 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 additi onal 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: −
Never touch the electrical cables of the ignition system.
− Absolutely avoid any jewellery, loose items 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 fuel system or on the electrical system:
− Always separate the car batter y 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 ma jor operating problems and also vehicle
damage!Overview of the engine compartment

additives.

Caution
•
Other coolant additives may cause operational problems which, in particular,
involves significantly reduci ng the anticorrosion effect.
•
Any faults or problems resulting from corrosion may cause a loss of coolant
and, as a consequence of this, re sult in major engine damage.
Inspecting the coolant levelThe coolant expansion bottle is located in the engine compartment on the right.
– Switch the engine off.
–Open the bonnet page 130. – Check the level of coolant in the coolant expansion bottle 
fig. 124. The
coolant level when the engine is cold must lie between the (MIN) and
(MAX) markings. The level may also rise slightly above the (MAX) marking
when the engine is warm.
If the coolant level in the reservoir is too low, this is indicated by the warning light
in the instrument cluster page 25, “Coolant temperature/coolant level  ”. We
nevertheless recommend inspecting the coolant level 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 re servoir. 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 expan-
sion bottle which is completely free of leaks if the coolant boils as a result of over-
heating and is forced out of the cooling system.
WARNING
Read and observe the warning notes page 131, “Working in the engine
compartment” before working in the engine compartment.
Caution
One should contact a specialist garage as soon as possible if the source of over-
heating 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. 124 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 the system, must comply with one
specific specification  page 133. Do not use an altern ative additive if the coolant
additive G13 is not available in an emergency. Just top up the system with water and

as soon as possible arrange adjustment
to correct the mixing ratio of water and
coolant additive again by a specialist garage.
Only use fresh coolant for topping up the system.
Do not fill up over the “MAX” marking! Exce ss coolant which is heated up is forced
out of the cooling system through the pressu re 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.
WARNING
•
The cooling system is pressurized! Do not open the cap of the coolant expan-
sion 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 your eyes, rinse out your eyes immediately
with clear water and contact a doctor as soon as possible.
•
You should also consult a doctor wi thout delay if you have inadvertently
swallowed coolant.Caution
Do not continue your journey if for some reason it is not possible under the condi-
tions prevailing to top up with coolant. Switch the engine off and obtain profes-
sional 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 comp liance 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 workin g 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 130.
– Inspect the brake fluid level in the reservoir fig. 125 . 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 the brake system, however, if the fluid level
drops significantly within a sh ort time or if it drops below the “MIN” marking. If the
