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 .

- If you get battery acid in your eyes or
on your skin, immediately rinse with
cold water for several minutes and get
medical attention.
- If you should ingest any battery acid,
seek medical attention immediately.
- Do not expose the battery to an open
flame, electric sparks or an open light .
- Do not smoke.
- Do not interchange the positive and neg-
ative cables .
- When working on the battery, be sure
not to short-circuit the terminals with
tools or other metal objects. This would cause the battery to heat up very quickly,
which could lead to damage or explosion
and personal injury .
- When a battery is charged, it produces
hydrogen gas which is explosive and
could cause personal injury .
- Always keep the battery well out of the
reach of children .
- Before work is done on the electrical sys
tem, disconnect the negative ground ca
ble.
- Before performing any work on the elec trical system, switch off the engine and
ignition as well as any electrical equip
ment. The negative cable on the battery
must be disconnected.
If you are just go

off the anti-theft alarm system! Other
wise you will set off the alarm.
- When disconnecting the battery, first
disconnect the negative cable and then
the positive cable.
- Before reconnecting the battery, make
sure all electrical consumers are switch
ed off. Reconnect the positive cable first
and then the negative cable. Never inter
change the cables - this could start a fire!
Checking and filling 237
- Never charge a frozen or a thawed-out
battery . It could explode! If a battery has
frozen, then it must be replaced. A dis
charged battery can freeze over at 32 °F
(0 oc).
-Make sure the vent hose is always attach
