A
WARNING
,~
- The cooling system is under pressure and
can get very hot. Reduce the risk of scalding
from hot coolant by following these steps.
- Turn
off
the engine and allow it to cool
down.
- Protect your face, hands and arms from
escaping fluid and steam by covering the
cap with a large, thick rag.
- Turn the cap slowly and very carefully in a
counter-clockwise direction while applying
light, downward pressure on the top of
the cap.
- To avoid being burned, do not spill anti-
freeze or coolant on the exhaust system or
hot engine parts. Under certa in cond i-
tions, the ethylene glycol in eng ine cool-
ant can catch fire.
- Antifreeze is poisonous. Always store anti-
freeze in its original container and well out
of the reach of children.
- If you dra in the coolant, it must be caught
and safely stored in a proper conta iner
clearly marked "poison".
- Do not add coolant if the expansion tank is
empty. Air could enter the cooling system
and damage the eng ine. If this is the case,
do not continue driving. Seek professional
ass istance.
- Coolant pollutes the environment and could
cause an eng ine fire. Excess coolant will be
forced out through the pressure relief valve
in the cap when the engine becomes hot.
- If, in an emergency, only wate r can be add-
ed, the correct ratio betwee n wate r and an-
tifree ze

For the sake of the environment
Drained coolant sho uld not be reused. Always
dispose of used coolant while obse rving all
environment al regulat ions.

Radiator fan
The radiator fan switches on automatically by it-
self .
The radiator fan is driven by the engine via the V-
belt. The viscous clutch regulates t he speed of
the fan accord ing to the temperature of the cool-
ant .
An auxiliary electr ic radiator fan* switches on and
off
depend ing on coolant temperature and other
vehicle operating conditions.
After you switch the engine
off,
the auxiliary fan
can continue running for up to 10 minutes - even
with the ignition
off.
It can even switch on aga in
later by itself
Q
.&,
if
- the temperature of the engine coolant rises due
to the heat build-up from the engine in the en-
gine compartment, or
- the engine compartment heats up because the
vehicle is parked in intense sunlight.
A
WARNING
- To reduce the risk of persona l injury never
touch the radia tor fan .
- The auxiliary electr ic fan is temperature
controlled and can switch on suddenly even
when the engine is not running.
- The auxiliary radiator fan switches on auto-
mat ically when the eng ine coolant reaches a
certa in temperature and will continue to run
until the coolant t emperature drops.
