If you see steam and/or spray
coming f rom under the hood, turn
of f the engine.
If you do not see steam or spray,
leave the engine running and
watch the temperature gauge. If
the high heat is due to overloading
(climbing a long, steep hill on a
hot day with the A/C running, for
example), the engine should start
to cool down almost immediately.
If it does, wait until the tempera-
ture gauge comes down to the mid-
point then continue driving. Saf ely pull to the side of the road.
Put the transmission in Neutral or
Park and set the parking brake.
Turn of f the heating and cooling/
climate control system and all
otheraccessories.Turnonthe
hazard warning indicators.
Keep the ends of the jumper cables
away from each other and any metal
on the vehicle until all are
disconnected. Otherwise, you may
cause an electrical short.
The pointer of your vehicle’s
temperature gauge should stay in
the midrange under most conditions.
Itmaygohigherif youaredrivingup
a long steep hill on a very hot day. If
it climbs to the red mark, you should
determine the reason. Your vehicle can overheat for several
reasons, such as lack of coolant or a
mechanical problem. The only
indication may be the temperature
gauge climbing to or above the red
mark. Or you may see steam or
spray coming f rom under the hood.
In either case, you should take
immediate action.

Steam and spray from an
overheated engine can
seriously scald you.
Do not open the hood if steam
is coming out.
Driving with the temperature gauge
pointer at the red mark can cause
serious damage to your engine.

If the temperature gauge stays at
the red mark, turn of f the engine.
Wait until you see no more signs
of steam or spray, then open the
hood.
If you don’t f ind an obvious leak,
check the coolant level in the
radiator reserve tank (see page). If the level is below the
MIN mark, add coolant to halfway
between the MIN and MAX marks.
If there was no coolant in the
reserve tank, you may also have to
add coolant to the radiator. Let the
engine cool down until the pointer reaches the middle of the tempera-
ture gauge, or lower, bef ore check-
ing the radiator.
Using gloves or a large heavy
cloth, turn the radiator cap
counterclockwise, without pushing
down, to the f irst stop. This
releases any remaining pressure in
the cooling system. After the
pressure releases, push down on
the cap and turn it until it comes
off.
Look f or any obvious coolant leaks,
such as a split radiator hose.
Everything is still extremely hot,
so use caution. If you f ind a leak, it
must be repaired bef ore you
continue driving (see
on page ). Start the engine and set the
temperature control dial to
maximum (climate control to
FULL AUTO at 90°F/32°C). Add
coolant to the radiator up to the
base of the f iller neck. If you do
not have the proper coolant
mixture available, you can add
plain water. Remember to have
the cooling system drained and
ref illed with the proper mixture as
soon as you can.
If the temperature stays normal,
check the coolant level in the
radiator reserve tank. If it has
gone down, add coolant to the
MAX mark. Put the cap back on
tightly. Put the radiator cap back on
tightly. Run the engine and watch
the temperature gauge. If it goes
back to the red mark, the engine
needs repair. (See
on page .)

Removing the radiator cap
while the engine is hot can
cause the coolant to spray out,
seriously scalding you.
Always let the engine and
