respond w ith maximum stopp ing power
in critical situations. You must allow for
increased brak ing distances . The extra
distance used up by fad ing brakes could
lead to an acc ident.

234 Checking and filling
scalding from hot coolant by following
these steps .
- Turn off the eng ine and a llow it to cool
down.
- Protect your face, hands and arms from escaping flu id and steam by cover ing
the cap with a large, thick rag .
- Turn the cap slowly and very carefully
i n a counter-clockwise direction while
apply ing l ight, downwa rd p ress ure on
the top of the cap .
- To avo id being burned, do not sp ill an­
tifreeze or coolant on the exhaust sys­
tem or hot engine parts . Under certain
conditions, the ethylene glyco l in en­
gine coolant can catch f ire .
- Antifreeze is poisonous . Always store an­
tifreeze in its or iginal container 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 clear ly marked "poison".
@ Note
- Coolant po llutes the env ironment and
could cause an engine fire . Excess coo l­
ant will be forced out through the pres­
sure re lief valve in the cap when the en­
gine becomes hot.
- If, in an emergency, on ly water can be
added, the correct ratio between water
and antifreeze
c::> page 232 must be re­
stored as soon as possible .
@ For the sake of the environment
Drained coolant should not be re used. Al­
ways dispose of used coolant while observ­
ing all environmental regulat ions .
Radiator fan
The radiator fan switches on automatically by
itself
An auxiliary e lectr ic radiator fan switches on
and off depending on coolant temperature
and other vehicle operating cond itions. After you switch the engine off, the aux
iliary
fan can cont inue running for up to 10 minutes
- even w it h the ignition off. It can even switc h
on again later by itself
c::> .&. , if
- the temperatu re 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.
A WARNING
-- To reduce the risk of persona l injury nev-
er touch the radiator fan.
- The a uxiliary electric fan is temperat ure
contro lled and can sw itch on suddenly
even when the engine is not running.
- The auxiliary radiator fan switches on a u­
tomatically when the engine coo lant
reaches a certain temperature and will
continue to run until the coolant temper­
ature drops .
