as soon as possible by a suitably quali-
fied workshop.
3.
Add coolant up to the upper level mark-
ing. Aer adding the coolant, the cool-
ant level must be between the mark-
ings on the coolant expansion tank
→ Fig. 208.
4. Close the cap tightly.
5. Check the coolant level aer one day. If
the level in the coolant expansion tank
again drops below the “min” mark, go
to a suitably qualified workshop and
have the cooling system checked.
NOTICE
Coolant expands when it is heated. If cool-
ant is topped up above the marked area,
exc
ess coolant may escape and cause
damage to the vehicle.
·
Do not fill coolant above the top edge of
the marked area of the coolant expan-
sion tank.
NOTICE
Air may have entered the cooling system if
there is no longer any c
oolant in the cool-
ant expansion tank. This could cause dam-
age to the engine.
·
Do not drive on.
·
Do not add any coolant.
·
Seek expert assistance.
NOTICE
Using water other than distilled water can
c
ause corrosion in the engine due to the
chemical components contained in it. This
can lead to engine failure.
·
Use only distilled water for refilling.
·
Have the fluid in the cooling system re-
placed completely by a suitably qualified
workshop if you have not added distilled
water.
NOTICE
Use of the incorrect service fluids c
an cause
serious malfunctions and result in engine
damage.
·
When refilling or replacing service fluids,
ensure that you pour the correct service
fluids into the appropriate openings.
Troubleshooting
Please refer to at the start of the
chapt
er on page 336.
Coolant
The warning lamp fla
shes red. The coolant
temperature is too high or the coolant level
is too low.
Do not drive on! The engine could other-
wise be dama
ged.
1. Stop the vehicle as soon as possible
and when safe to do so → page 194.
2. Switch o the engine.
3. Allow the engine to cool down.
4. Check the coolant level in the coolant
expansion tank → page 337.
5. Do not drive on or leave the engine run-
ning if the warning lamp does not go
out even though the coolant level is
correct.
6. Seek expert assistance.
Brake uid
Introduction
Brake fluid will gra
dually absorb water
from the surrounding air. The brake system
will be damaged if there is too much water
in the brake fluid. The boiling point of the
brake fluid is also considerably reduced by
the water content. Heavy use of the brakes
may cause a vapour lock in the brake sys-
tem if the water content is too high. Vapour
locks reduce levels of braking power, con-
siderably increase braking distance and can
even cause the brake system to fail com-
pletely. Your own safety and that of other
road users depends on having a brake sys-
tem that functions properly at all times.
WARNING
Brake fluid is toxic. C
ontact with brake
fluid, particularly if swallowed, can lead
to serious or fatal injuries.
·
Consult a doctor immediately if you
have swallowed brake fluid.
