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
2l , 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 .

Closing the engine hood
- Pull the hood down until the pressure from the struts 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.

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.
• Apply the parking brake.
Safety first
& WARNING (continued)
• 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 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:
- First, fully apply the parking brake, move selector lever to
