Engine compartment
Be especially careful when cleaning the engine compa rt­
men t.
Always switch off the ignition before cleaning the engine=:>& .
Plenum panel
Remove leaves from the plenum panel in front of the win dshi eld
unde r th e eng ine hood . T hi s prevents the water d rain holes from
becoming b locked, and it prevents debris from entering the vehicle
inter io r th rough the heat ing and vent ilation ducts .
Corrosion protection
The eng ine compartment and transmission have been cor rosion­
protected at the factory.
Good ant i-cor rosion treatment is very impo rtant , pa rtic ular ly in the
w inter . If the vehicle is frequently driven on sa lt treated roads, the
en tire eng ine compar tment and plenum p anel sho uld be thoroug hly
cleaned at the end of winter and retreated to prevent salt damage. At
t he same t ime, the underside of the vehi cle should be washed as well.
If the e ng ine compartment is clea ned at any t ime with grease
removing so lutions
5>, or i f you have the engine washed , the anti ­
co rros io n treatment is a lmost a lways removed as w ell.
It is t herefore
essential to have a long-last ing corrosion p rotect ion reapplied to all
surfa ces, seams, jo ints and compo nents in the engi ne co mpa rt ment .
& WARNING
Be aware: The engine compartment of any motor vehicle is a
potentially hazardous area .
• Before working in the engine compartment, be sur e to read the
information =:>
page 218.
S) Use on ly th e co rr ect clean ing so lut ions. Never use gaso line or diese l fuel.
& WARNING (c on tinued )
• Before reaching into the front plenum panel , alway s remove
the ignition key. Otherwise, the windshield wiper system could unintentionally be switched on , possibly causing personal injury
from the moving wiper linkage.
• Never reach into the area around or touch the radiator fan. The
auxiliary fan is temperature controlled and can switch on suddenly
· ev en when the ignition is off.
• Do not wash, wax or dry the engine with th e engine running.
Moving or hot pa rts could injure you.
• Do not clean the underside of the chass is, fenders, wheel

Closing the engine hood
- Pull the hood down until the pressure from the strut is
reduced.
- Let the hood
drop down and latch in place . Do not try to
push it shut;
it may fail to engage=> &.
& WARNING
A hood that is not completely latched could fly up and block your
view while driving.
• When you close the engine hood, check it to make sure the
safety catch has properly engaged. The hood should be flush with
the surrounding vehicle body parts.
• If you notice while driving that the hood is not secured prop­
erly, stop at once and close it. •
Working in the engine compartment
Be especially careful whenever you work in the engine
compartment!
Whenever you must perform any work in the engine compartment,
for example checking and filling different fluids, there is a risk of
injury, burns and accidents. To prevent personal injury always
observe the following WARNINGS. The engine compartment of any
vehicle is a hazardous area!~
&
& WARNING
To help avoid injury, before you check anything under the hood :
• Turn off the engine.
• Remove the ignition key.
• Set the parking brake fully.
& WARNING (continued)
• Move selector lever of automatic transmission to "P" (Park);
put manual transmission in Neutral.
• 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 compart­
ment. Wait until no steam or coolant can be seen or heard before
carefully opening the hood.
• Keep children away from the engine compartment.
• Never spill fluids on hot engine components. 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.
• 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 immediately 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: .,_

as possible.
~ For the sak e of the environment
Ora i ned coolant should not be reused . Always dispose of used coolant
while observing all environmental regulations .•
Radiator fan
The radiator fan switches on automatically by itself.
T he electric radiator fan is controlled by thermoswitches that switch
on and off depending on coolant a nd engine compartment tempera­
tures.
An auxilia ry e lectr ic rad iator fan* sw itches on a nd off depend ing on
coo lant temperature and other vehicle operation cond itions .
After switch ing off t he engine, the auxiliary fan -even with the igni­
tion off -can continue running for up to 10 minutes . It can even
switch on again later by itself=>& , if
• the temperature of the engine coolant rises due to the hea t build­
up from the engine in the engine compartment, or
• the engine compar tment hea ts up because the vehi cle is parked in
intense sunlight.
& WARNING
• To reduce the risk of personal injur y never tou ch the radi ator
fan .
• The auxiliary ele ctric fan i s temperatur e controll ed and can
switch on sudd enly even wh en the engine is not running .

"MAX" markings ~ fig . 167 .
The brake fluid reservoir is located at the rear partition of the engine
compartment on the left side=>
page 227.
The fluid level may drop
slightly after some time due to the auto­
m atic adjus tment of the brake pads. This is not cause for alarm .
If the brake fluid level falls
considerably below the "MIN" mark, t he
brake warning/ind icator light (U .S. models :
BRAKE, Canadian mode ls:
ill ) will come on=> page 15 and=> page 32. Do not continue to
operate the vehicle . The complete brake system should be thorough ly
