Checking and refilling levels
climbing on mountain passes, the oil level
should preferably be kept within area A ,
but
no higher .
A w
arning lamp will appear on the instrument
panel ››› page 34, Engine oil if the oil lev-
el is too low. In this case, check the oil level
as soon as possible. Top up with the required
amount of oil. CAUTION
● The oil level must never exceed area A›››
Fig. 111. Risk of damage to the exhaust
sy s
tem!
● If the engine oil cannot be topped up under
the given conditions, do not drive on! Stop the engine and seek
the professional assis-
tance of an Official Service, as this could
cause serious damage to the engine. Topping up engine oil

Checking the engine oil level .
– Unscrew the cap from the filler opening.
– Put in the specified grade of oil 0.5 litres at
a time ›››
page 135 .
– Chec k
the oil level ›››
page 136.
– Replace the oil filler cap carefully and push
the dipstick all the way in. Changing engine oil Engine oil must be changed with the frequen-
cy indicated in the Maintenance Programme
or according to the service interval indicator
››› page 45. CAUTION
Do not mix engine oil with additives. Risk of
damage to the engine! Damage caused by
these products is not covered by the warran-
ty. Note
Wash your skin thoroughly if it comes into
contact with engine oil. Coolant
General notes The cooling system is factory-filled with an
anti-freeze product.
Coolant consists of a mixture of water and
40% anti-freeze additive. This mixture gives
the required anti-freeze protection at temper-
atures down to -25 °C (-13 °F) and protects
the cooling and heating system against cor-
rosion. It also prevents scaling and raises the
boiling point of the coolant considerably.The coolant concentration must not be re-
duced by adding water, even in warmer sea-
sons or in warm countries.
The concentration
of the anti-freeze additive in the coolant
must be at least 40 %.
If greater anti-freeze protection is required in
very cold climates, the proportion of the anti-
freeze additive can be increased, but only up
to 60% (anti-freeze protection down to ap-
proximately -40 °C (-40 °F)). Exceeding this
proportion reduces anti-freeze protection and
the cooling effect.
Coolant fluid with protection down to -35 °C
(-31 °F) is added at the factory in vehicles
destined for countries with a cold climate. In
these countries, the concentration of coolant
should always be kept above 50%.
The type of anti-freeze to be used for topping
up is indicated on the coolant tank cover
››› Fig. 112 . CAUTION
● Anti-freeze that does not correspond to the
correct specification may particularly affect
corrosion protection considerably.
● Faults caused by corrosion may lead to
coolant leaks. Risk of serious engine faults! 137
