Driving when your engine is badly overheated can
cause some fluids which may have leaked into the
engine compartment to catch fire. You could be
seriously burned.Steam from an overheated engine can cause serious
burns and can occur just by opening the engine
hood. Stay away from the engine if you see or hear
steam coming from it.Turn off the engine, get out of the vehicle and do
not stand near the vehicle until it cools down.

cluster displayPractical hintsCar care Index Fuses
Most of your vehicle’s electrical components are fused
with safety fuses. With the exception of the brake lights,
all individual lighting system components are
electronically fused. Before replacing a blown safety
fuse, determine the cause of the short circuit. Always
observe amperage and color of fuse.
The circuit for components is protected by a cycled
circuit breaker interrupted if too much current is being
drawn. The circuit closes automatically after a short
time; the circuit is broken again if the malfunction
reoccurs.
A lways us e a new fus e for re placeme nt. Never atte mp t to
repair or bridge a blown fuse.
A fuse chart is located in fuse box (1).
A fuse extractor is located in the auxiliary fuse box in
the trunk, see page 317.Fuse box in the passenger compartment

Hood
Wa r n i n g !
To help prevent personal injury, stay clear of
moving parts when the hood is open and the engine
is running. Be sure the hood is properly closed
before driving. When closing hood, use extreme
caution not to catch hands or fingers.The radiator fan may continue to run for
approximately 30 seconds or even restart after the
engine has been turned off. Stay clear from fan
blades.If you see flames or smoke coming from the engine
compartment, or if the coolant temperature gauge
indicates that the engine is overheated, do not open
the hood. Move away from vehicle and do not open
the hood until the engine has cooled. If necessary,
call a fire department.
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, diagnostic socket) of the
ignition system
• with the engine running,
• while starting the engine,
• if ignition is “on” and the engine is turned
manually.
