fully opening the hood .
'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 per­
sonal injury always observe the following
WARNINGS. The engine compartment of any
vehicle is a hazardous area
¢ ,&. .
A WARNING
To help avoid injury, before you check any­
thing under the hood:
- Turn off the engine.
- Switch off the ignition .
- 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:

~ Place a thick rag over the coolant expansion
tank ¢
page 232, fig . 191 and ca refull y
twist the cap counter-clockwise ¢ ,A.
~ Add coolant mixed in the correct ratio
¢page 231, Coolant.
~ Twist the cap on again tightly .
Replacement engine coolant must conform to
exact specifications ¢
page 231, Coolant .
We recommend using on ly coolant addi-
tive
Gl2++, Gl3 or in an emergency G l2+ . Do
not use a different add itive. In an emergency
use plain water unti l you can get the correct
addit ive and ca n restore the correct ratio. This
should be done as soon as possible .
If you have lost a considerable amount of
coolant, then you should add co ld a ntifree ze
and cold water only when the eng ine is co ld.
A lways use
new engine coolant when ref illing.
D o no t fill coolan t above the "M AX " mar k. Ex­
