& WARNING
- The cooling system is under pressure and
can get very hot. Reduce the risk of scald ing
from hot coolant by following these steps.
- Turn off the engine and allow it to coo l
down.
- Protect your face, hands and arms from
escaping flu id and steam by cover ing the
cap with a large, thick rag.
- Turn t he cap slowly and very carefully in a
counter-clockwise d irection while applying
light, downward pressure on t he top of
the cap.
- To avoid bei ng bu rned, do not spill anti-
free ze or coo lant on the exhaust syst em or
hot engi ne parts. Under certa in cond i-
tions, the ethylene glycol in eng ine cool -
ant can catch fire .
- Ant ifreeze is poisonous. Always store an ti-
freeze in its original con tainer and well ou t
of the reach of children.
- If you dra in the coolant, it m ust be ca ught
and safely stored in a proper conta iner
clearly marked "poison" .
(D Note
- Do not ad d coolant if t he expa nsion tank is
empty. Air cou ld enter the cooling syst em
and damage the eng ine. If this is the case,
do not continue driving. Seek professional
ass istance.
- Coolant po llutes the environment and could
ca use an eng ine fire . Excess coolant will be
fo rced out through the pressure relief valve
in the cap when the eng ine becomes hot.
- If, in an emergency, only wate r can be add-
ed, the correct ratio between water and an-
tifreeze¢
page 22 7 must be restored as
soon as possib le.
@) For the sake of the environment
Drained coolant sho uld not be reused. Always
dispose of used coolant while observing all

Ch e ck ing an d Filling
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 o n coo lant temperature and other
vehicle operating conditions.
After you switch the engine off, the auxiliary fan
can continue ru nning for up to 10 minutes - even
with the ignition off. It can even switch on aga in
later by itself ¢ ,&, 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 beca use the
veh icle is parked in intense sunlight.
& WARNING
- To reduce the risk of persona l injury neve r
touch the radia tor fan .
- The auxiliary e lectr ic fan is temperature
controlled and can switch on s uddenly even
when the engine is not ru nning .
- The a uxiliary radiator fan sw itches on auto-
mat ically when the eng ine coolant reaches a
certa in temperature a nd will continue to run
until the coolant t emperature drops.
