166 Checking and filling
-Apply the parking brake.
- Move selector lever to "P" (Park).
- Always let the engine cool down. Hot
components will burn skin on contact.
- To reduce the risk of being burned, never
open the hood if you see or hear steam
or coolant escaping from the engine
compartment . Wait until no steam or
coolant can be seen or heard before care­
fully opening the hood.
- Keep children away from the engine com­
partment .
- Never spill fluids on hot engine compo­
nents. They can cause a fire.
- Never touch the radiator fan. The auxili­
ary electric fan is temperature controlled
and can switch on suddenly.
- Never open the coolant reservoir cap
when the engine is still warm. The cool­
ant system is pressurized and hot cool­
ant could spray out .
- Protect your face, hands and arm from
steam or hot engine coolant by placing a
thick rag over the cap when you open the coolant reservoir .
- Do not remove the engine cover under
any circumstances . This increases the
risk of burns.
- If work on the fuel system or the electri­
cal system is necessary:
- Always disconnect the battery .
- Never smoke or work near heaters or
open flames. Fluids in the engine com­
partment could start a fire.
- Keep an approved fire extinguisher im­
mediately available.
- To avoid electrical shock and personal in­
jury while the engine is running or being
started, never touch:
- Ignition cables
- Other components of the high voltage
electronic ignition system.
- If you must perform a check or repair
with the engine running: -
First, fully apply the parking brake,
move selector lever to "P" (Park) .
- Always use extreme caution to prevent
clothing, jewelry, or long hair from get­
ting caught in the radiator fan, V-belts
or other moving parts, or from contact­ ing hot parts. Tie back hair before
starting, and wear no clothing that will hang or droop into the engine.
- Minimize exposure to emission and chemical hazards~&, .

down.
- Protec t your face, hands and arms from
escap ing fl uid and steam by cover ing
the cap with a large, thick rag.

applying light, downward 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
g ine coolant can catch fire.
- Antifreeze is poisonous. Always store an ­
t ifreeze 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
ta iner clearly marked "poison".
(D Note
- Coolant po llutes the environment and
could cause an engine fire. Excess cool­
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, only water can be
added, the correct ratio between wate r
and antifreeze~
page 172 must be re­
stored as soon as possib le.
@) For the sake of the environment
Dra ined coolant should not be reused. Al­
ways dispose of used coolant while obse rv­
ing all environmental regulations .

tures.
An a uxiliary electric radiator fan* sw itches on

and other vehicle operat ion conditions .
After you switch the engine off, the aux iliary
fan can continue running for up to 10 minutes
-even w ith the ignition off. It can even switc h
on aga in later by itself
c> &. , 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.
