Stopping the engine
Applies to: vehicles with ig ni tion lock

.. Automatic transmission: Move the selector lev­
er to the P or N position .
.. Press on the ignition key. The engine is turned
off.
.. You can now remove the key .
Steering lock
The steering locks when you remove the ignition
key. The locked steering helps prevent vehicle
theft.
Emergency off
If it is necessary in unusual circumstances , the
engine can be switched off while the vehicle is
moving . The engine will be switched off if you
press on the key for an extended period.
A WARNING ,-
- Never turn off the engine before the vehicle
has come to a complete stop. The full func­
tion of the brake booster and the power
steering is not guaranteed. You must use
more force to turn or brake if necessary . Be­
cause you cannot steer and brake as you
usually would, this could lead to crashes
and serious injuries.
- For safety reasons, you should always park
your vehicle with the selector lever in P.
Otherwise, the vehicle could inadvertently
roll away .
Driving
-The radiator fan can continue to run for up
to 10 minutes even after you have turned
off the engine and removed the ignition key.
The radiator fan can also turn on again if the
engine coolant heats up because of intense
sunlight or heat build-up in the engine com­
partment.
- Always take the key with you whenever you
leave your vehicle. Otherwise, the engine
could be started or electrical equipment
such as the power windows could be operat­
ed. This can lead to serious injury.
- Never leave children or persons requiring as­
sistance unattended in the vehicle. The
doors can be locked using the remote trans­
mitter, preventing people from escaping
from the vehicle on their own in the event of an emergency. Depending on the time of
year, people inside the vehicle can be ex­ posed to very high or very low tempera ­
tures .
(D Note
If the engine has been under heavy load for
an extended period, heat builds up in the en­
gine compartment after the engine is switch ­
ed off -there is a risk of damaging the engine.
Allow the engine to run at idle for about two
minutes before switching it off.

Checking and Filling
compartment. Wait until no steam or cool­
ant 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).
- Always use extreme caution to prevent
clothing , jewelry, or long hair from get-
194
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

fornia to cause cancer and birth defects and
reproductive harm. In addition, certain flu­
ids contained in vehicles and certain prod­
ucts of component wear contain or emit
chemicals known to the State of California
to cause cancer and birth defects or other
reproductive harm .
- Battery posts, terminals and related acces­
sories contain lead and lead compounds,

A WARNING ,~
- The cooling system is under pressure and
can get very hot. Reduce the risk of scald ing
from hot coolant by following these steps.
- Turn
off the engine and allow it to coo l
down.
- Protect you r face, hands and arms from
escaping fluid and steam by cover ing the
cap with a large, thick rag.
- Turn the cap slowly and very carefully in a
counter-clockwise d irection while applying
light, downward p ressure on the top of
the cap.
- To avoid being burned, do not spill anti­
freeze or coolant on the exhaust system or
hot engine parts. Under certa in cond i­
tions, the ethylene glycol in eng ine cool­
ant can catch fire.
- Antifreeze is poisonous. Always store anti­
freeze in its orig inal container and well out
of the reach of children.
- If you dra in the coolant, it must be caught
and safely stored in a proper conta iner
clearly marked "poison".
- 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 driving . Seek professional
ass istance.
- Coolant pollutes the env ironment and could
cause an eng ine fire. Excess coolant will be
fo rced o ut through the pressure relief valve
i n the cap when the e ng ine be comes hot.
- If, in an emergency, only wate r can be add­
ed, the co rrect r atio betwee n wate r and an­
tifree ze
Q page 199 must be res to red as

off, the auxiliary fan
can continue running for up to 10 m inutes -even
with the ignition
off. It can even switch on aga in
later by itself
Q .& , if
- the temperature of the engine coolant rises due
to the heat build-up from the engine in the en­
gine compartment, or
- the engine compartment heats up beca use the
veh icle is parked in intense sunlight.
