WARNING
Only change the engine oil yourself if you
have the specialist knowl
edge required!
●
Before opening the bonnet, read and ob-
serve the warnings
›››
page 322.
●
Wait for the engine to cool down. Hot oil
may cause burn injuries.
●
Wear eye protection to avoid injuries,
such as acid burns, caused by splashes of
oil.
●
When removing the oil drain plug with
your fingers, keep your arm horizontal to
help prevent oil from running down your
arm.
●
Wash your skin thoroughly if it comes into
contact with engine oil.
●
Engine oil is poisonous! Used oil must be
stored in a safe place out of the reach of
children.
CAUTION
No additives should be used with engine oil.
This could result in engine damage
. Any
damage caused by the use of such addi-
tives would not be covered by the factory
warranty.
For the sake of the environment
●
Because of disposal problems and the
special t
ools and specialist knowledge re-
quired, we recommend that you have the
engine oil and filter changed by a Techni-
cal Service.
●
Never pour oil down drains or into the
ground.
●
Use a suitable container when draining
the used oil. It must be large enough to hold
all the engine oil.

Top up coolant when the level is below the
MIN (minimum) mark.
Checking coolant level
–
Park the vehicle in a horizontal position.
–
Switch the ignition off.
–
Read off the coolant level on coolant ex-
pansion tank. When the engine is cold, the
coolant level should be between the marks.
When the engine is hot, it may be slightly
above the upper mark.
Topping up coolant
–
Wait for the engine to cool down.
–
Cover the coolant expansion tank cap with
a cloth and carefully unscrew it to the left
›››
.
–
Top up the coolant only if there is still cool-
ant in the e
xpansion t
ank
, otherwise you
could damage the engine. If there is no
coolant in the expansion tank, do not con-
tinue driving. You should obtain professional
assistance
›››
.
–
If there is still some coolant in the expansion
t
ank
, t
op up to the upper mark.
–
Top up with coolant until the level becomes
stable.
–
Screw the cap back on correctly.
Any loss of coolant fluid normally indicates a
leak in the cooling system. Take the vehicle
straight to a specialised workshop to have
the cooling system examined. If there are no
leaks in the engine cooling system, a loss of
coolant can only occur if the coolant boils
and is forced out of the system as a result of
overheating.
WARNING
●
The cooling system is under pressur
e. Do
not unscrew the cap on the coolant expan-
sion tank when the engine is hot: risk of
burns!
