_& 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 a llow itto 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 slow ly 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 spi ll an­
tifreeze or coolant on the exhaust sys­
tem or hot engine parts . Under certain
conditions, the ethylene glycol in en­
g ine coolant can catch fire .
- Antifreeze is poisonous. Always store an­
tifreeze in its or iginal containe r and we ll
out of the reach of children.
- If you drain the coolant, it must be
caught and safely stored in a proper con­
tainer clearly marked "poison".
(D Note
- Coolant pollutes the env ironment and
could cause an engine fire. Excess cool­
ant will be forced out through the pres­
su re relief valve in the cap when the en­
gine becomes hot.
- If, in an emergency, only water can be
added, the cor rect ratio between water
and antifreeze ¢
page 227 must be re­
stored as soon as possib le.
@ For the sake of the environment
Drained coolant should not be reused . A l­
ways dispose of used coolant while obse rv­
ing all environmental reg ulations.

and other vehicle operat ing cond it ions .
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 again later by itself ¢&. , if
- the temperature of the engine coo lant rises
due to the heat build-up from the engine in
the engine compartment, or
- the engine compartment heats up because
the vehicle is parked in intense sunlight.
_& WARNING
-To reduce the risk of personal injury nev­
er touch the radiator fan .
- The auxiliary electric fan is temperature
controlled and can sw itch on suddenly
even when the engine is not running.
- The a uxiliary radiator fan sw itches on au­
tomatically when the engine coo lant
reaches a certa in temperature and will
continue to ru n until the coolant temper­
ature drops.
