5-15SERVICE AND APPEARANCE CARE

If the warning continues and you have not
stopped, pull over, stop, and park your
vehicle right away.
If there’s still no sign of steam, you can idle
the engine for three minutes while you’re
parked. If you still have the warning, turn
off the engine and get everyone out of the
vehicle until it cools down.
You may decide not to lift the hood, but to
get service help right away.Cooling SystemThe engine coolant surge tank is located in
the rear of the engine compartment on the
driver’s side.If the coolant inside the coolant surge tank
is boiling, don’t do anything else until it
cools down. The vehicle should be parked
on a level surface. Make sure that the air
conditioning is turned off.
The coolant level should be between the
MIN and MAX marks on the coolant surge
tank when the engine is cool. If it isn’t, you
may have a leak at the pressure cap or in
the radiator hoses, heater hoses, radiator,
water pump or somewhere else in the cool-
ing system.If there seems to be no leak, with the
engine on, check to see if the electric
engine cooling fan is running. If the engine
is overheating, the fan should be running.
If it isn’t, your vehicle needs service.
How to Add Coolant to the Coolant
Surge Tank
If you haven’t found a problem yet, check
to see if coolant is visible in the surge tank.
If coolant is visible but the coolant level
isn’t between the MIN and MAX marks,
add a 60/40 mixture of clean, drinkable
water and proper coolant at the coolant
surge tank, but be sure the cooling system,
including the coolant surge tank pressure
cap, is cool before you do it. See “Engine
Coolant” in this section for more informa-
tion.
If no coolant is visible in the surge tank,
add coolant as follows:
WARNING
An electric engine cooling fan under
the hood can start up even when the
engine is not running and can injure
you. Keep hands, clothing and tools
away from any underhood electric
fan.
WARNING
Heater and radiator hoses, and other
engine parts, can be very hot. Don’t
touch them. If you do, you can be
burned.
Don’t run the engine if there is a leak.
If you run the engine, it could lose all
of the coolant. That could cause an
engine fire, and you could be burned.
Get any leak fixed before you drive
the vehicle.
CAUTION
Engine damage from running your
engine without coolant isn’t covered
by your warranty.
CAUTION
This vehicle has a specific coolant fill
procedure. Failure to follow this pro-
cedure could cause your engine to
overheat and be severely damaged.

SERVICE AND APPEARANCE CARE

1) Park the vehicle on a level surface. You
can remove the coolant surge tank
pressure cap when the cooling system,
including the coolant surge tank pres-
sure cap and upper radiator hose, is no
longer hot. Turn the pressure cap
slowly counterclockwise (left) about two
or two and one-half turns. If you hear a
hiss, wait for that to stop. This will allow
any pressure still left to be vented out
the discharge hose.
WARNING
Never turn the cap when the cooling
system, including the coolant surge
tank pressure cap, is hot.
Steam and scalding liquids from a
hot cooling system can blow out and
burn you badly. They are under pres-
sure, and if you loosen the coolant
surge tank pressure cap – even a lit-
tle – they can come out at high
speed. Wait for the cooling system
and coolant surge tank pressure cap
to cool if you ever have to loosen the
pressure cap.
WARNING
Adding only plain water to your cool-
ing system can be dangerous. Plain
water, or some other liquid such as
alcohol, can boil before the proper
coolant mixture will. Your vehicle’s
coolant warning system is set for the
proper coolant mixture. With plain
water or the wrong mixture, your
engine could get too hot but you
wouldn’t get the overheat warning.
Your engine could catch fire and you
or others could be burned. Use a 60/
40 mixture of clean, drinkable water
and a proper coolant.
L3U5019A
CAUTION
In cold weather, water can freeze and
crack the engine, radiator, heater
core and other parts. Use the recom-
mended coolant and the proper cool-
ant mixture.
WARNING
You can be burned if you spill coolant
on hot engine parts. Coolant con-
tains ethylene glycol and it will burn
if the engine parts are hot enough.
Don’t spill coolant on a hot engine.

one for each headlamp, in the fuse block.
An electrical overload will cause the lamps

lamp wiring checked right away.Windshield Wiper FusesThe windshield wiper motor is protected by
an internal circuit breaker and a fuse. If the
motor overheats due to heavy snow, etc.,
the wiper will stop until the motor cools. If
the overload is caused by some electrical
problem and not snow, etc., be sure to get
it fixed. Description Usage
