ponents 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 compart
ment. Wait until no steam or coolant can be
seen or heard before carefully 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 auxiliary
electric fan is temperature controlled and
can switch on suddenly.
- Never open the coolant reservoir cap when
the engine is still warm. The coolant system
is pressurized and hot coolant 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 electrical
system is necessary:
- Always disconnect the battery.
- Never smoke or work near heaters or open
flames. Fluids in the engine compartment
could start a fire.
- Keep an approved fire extinguisher imme
diately available.
- To avoid electrical shock and personal injury
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 of automatic transmission
to P (Park).
Checking and Filling
-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 contacting hot parts. Tie back hair before starting,
and do not wear clothing that will hang or
droop into the engine.
- Minimize exposure to emission and chemi
cal hazards

(I) Note
When adding fluids, always make sure that
they are poured into the proper container or
filler opening, otherwise serious damage to

Checking and Filling
-To avoid bein g burned, do not spill anti
f reeze or coolant on the exhaust system or
hot engine parts. Under certain condi
tions, the ethylene glycol in engine cool ant can catch fire.
- Antifreeze is poisonous . Always store anti
freeze in its original container and well out
of the reach of children .
- If you dra in the coolant, it must be ca ught
and safely stored in a proper conta iner
clearly marked "poison".
(D Note
- Do not add coolant if the expansion tank is
empty . Air cou ld enter the cooling system
and damage the eng ine .
If this is the case,
do not continue dr iving . Seek professional
ass istance.
- Coolant pollutes the e nvironment a nd could
cause an eng ine fire. Excess coolant will be
fo rced o ut through the pressu re relief valve
i n the cap when the eng ine be comes hot .
- If, in an emergency, o nly wate r can be add
ed, the co rrect ratio between water and an
tifree ze ~

soon as possib le .
@) For the sake of the environment
Drained cool ant sho uld not be reused. Always
dispose of used coo lant w hile obse rving all
environmenta l regulatio ns.
Radiator fan
The radiator fan switches on automatically by it
self.
The radiator fan is dr iven by the eng ine v ia the V
be lt . The visco us cl utch regula tes the speed of
the fan acco rding to the tempera ture of t he cool
ant.
An aux iliary ele ct ric radiator fan* swit ches on and
off depending on coolant tempera tu re and o ther
ve hicl e operat ing cond itions .
After you switch the engine off , the auxiliary fan
can cont inue runn ing fo r up to 10 minutes - even
228
with the ignition off . It can even switch o n aga in
l ater by itself~.&. , if
- the tempera ture of the engine coolant rises d ue
to the hea t build- up from the engine in the en
gine compartment, or
- the engine compa rtme nt heats up bec ause the
veh icle is parked in intense s unlight.
A WARNING
- To reduce the r isk of personal injury never
touch the radiator fan.
- The a uxiliary e lectric fan is temperat ure
controlled and can switch on suddenly even
when the engine is not runn ing .
-
-The a uxiliary radiator fan switches on a uto
mat ically when the eng ine coolant reaches a
certain temperature and will continue to r un
until the coo lant temperature drops.
