244 OperationEngine compartmentHood OpeningWarning!
G
Do not pull the release lever while the
vehicle is in motion. Otherwise the hood
could be forced open by passing air flow.Warning!
G
The exhaust areas on the engine hood and
between the doors and front wheels get very
hot. Avoid contact with them, otherwise
there is the risk of severe burns.
Warning!
G
To help prevent personal injury, stay clear of
moving parts when the hood is open and the
engine is running. Make sure the hood is
properly closed before driving. When closing
the hood, use extreme caution not to catch
hands or fingers.
The radiator fan may also start at any time
automatically, even after the SmartKey has
been removed from the starter switch. Stay
clear of fan blades.Warning!
G
Engine components may become very hot.
Avoid contact with them, otherwise there is
the risk of severe burns.
Warning!
G
The engine is equipped with a transistorized
ignition system. Because of the high voltage
it is dangerous to touch any components
(ignition coils, spark plug sockets, diagnos-
tic socket) of the ignition system

with the engine running


while starting the engine


if ignition is “on” and the engine is
turned manually

245 Operation
Engine compartment
The release lever is located in the driver's
footwell.
1Release leverThe hood folding mechanism is disengaged
in two stages.

Pull release lever1 downwards.
This completes the first stage.
!Make sure the windshield wipers are
not folded away from the windshield.
Otherwise the windshield wipers or the
hood could be damaged.
Make sure there is sufficient clearance
before opening the hood. A minimum
clearance in front of the vehicle of 3/4ft (25 cm) is required.
iIf it was not possible to release the
hood, pull the release lever downwards
more firmly.

250 OperationEngine compartmentCoolant
The engine coolant is a mixture of water
and anticorrosion/antifreeze. To check
the coolant level, the vehicle must be
parked on level ground and the engine
must be cool.
The coolant expansion tank is located on
the passenger side of the engine compart-
ment.
1Expansion tank

Using a rag, turn cap slowly approxi-
mately one half turn to the left to
release any excess pressure.

Continue turning the cap to the left and
remove it.
The coolant level is correct if the level

for cold coolant: reaches the upper
mark on the bracing rib of the ex-
pansion tank (arrow)


for warm coolant: is approximately
0.4 in (1 cm) higher

Add coolant as required.

Replace and tighten cap.
For more information, see “Coolants”
(
page 381).
Warning!
G
In order to avoid any possibly serious burns:

Use extreme caution when opening the
hood if there are any signs of steam or
coolant leaking from the cooling system,
or if the coolant temperature gauge indi-
cates that the coolant is overheated.


Do not remove pressure cap on coolant
reservoir if coolant temperature is
above 194°F (90°C). Allow engine to
cool down before removing cap. The
coolant reservoir contains hot fluid and
is under pressure.


Using a rag, slowly open the cap
approximately
1/2 turn to relieve excess
pressure. If opened immediately, scald-
ing hot fluid and steam will be blown out
under pressure.


Do not spill antifreeze on hot engine
parts. Antifreeze contains ethylene
glycol which may burn if it comes into
contact with hot engine parts.
