LOW
TRAC
When your anti-lock system
is adjusting brake pressure
to help avoid a braking skid,
the anti-lock brake system
active light will come on.
Engine Coolant Temperature Light
This light tells you that
your engine coolant has
overheated or your
radiator cooling fan(
s)
are not working.
Slippery road conditions may exist if this light comes
on,
so adjust your driving accordingly. The light will
stay on for a few seconds after the system stops
adjusting brake pressure.
The anti-lock brake system active light also comes on
briefly when you turn the ignition key
to RUN. If the
light doesn’t come on then, have it fixed
so it will be
there to tell
you when the system is active. If you have been
operating your vehicle under normal
driving conditions, you should pull off the road, stop
your vehicle and turn off the engine as soon as possible.
In “Problems on the Road,” this manual shows what to
do. See “Engine Overheating” in the Index.

When you decide it's safe to lift the hood, here's what
you'll see:
3100 (Code M) Engine
A. Coolant Recovery Tank
B. Radiator Pressure Cap
C. Electric Engine Fans
3.4L DOHC (Code X) Engine
A. Coolant Recovery Tank
B. Radiator Pressure Cap
C. Electric Engine Fans

Downloaded from www.Manualslib.com manuals search engine An electric 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.
If the coolant inside the coolant recovery tank is boiling,
don't do anything else until it cools down.
The coolant level should be at or above the
COLD mark
on
a cold engine. The coolant level should be at or
above the
HOT mark on a hot engine.
If it isn't, you may have a leak in the radiator hoses,
heater hoses, radiator, water
pump or somewhere else in
the cooling system.

Downloaded from www.Manualslib.com manuals search engine 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 coolant. That could
cause an engine fire, and you could be burned.
Get any leak fixed before you drive the vehicle.
NOTICE:
Engine damage from running your engine
without coolant isn’t covered by your warranty.
If there seems to be no leak, with the engine on, check to
see
if the electric engine fans are running. If the engine
is overheating, both fans should be running.
If they
aren’t, your vehicle needs service.
How to Add Coolant to the Coolant
Recovery Tank
If you haven’t found a problem yet, but the coolant level
isn’t at
the COLD mark, add a 50/50 mixture of clean
water (preferably distilled) and DEX-COOL@
(silicate-fiee) antifreeze at the coolant recovery tank. (See
“Engine Coolant” in the Index for more information.)
’ Adding only plain water to your cooling system
can be dangerous. Plain water,
or some other
liquid like alcohol, can boil before the proper
coolant
mix will. Your vehicle’s coolant warning
system is set for the proper coolant mix. With
plain water or the wrong
mix, 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
50/50 mix of clean
water and DEX-COOL%oolant.

In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
Use the recommended coolant and the proper
coolant mix.
I A CAUTION:
- - I
You can be burned if you spill coolant OII not
engine parts. Coolant contains ethylene glycol
and it will burn if the engine parts are hot
enough. Don’t spill coolant on
a hot engine.
When the coolant in the coolant recovery tank is at the
COLD mark, start your vehicle.
If the overheat warning continues, there’s
one more
thing you can try. You can add the proper coolant
mix
directly to the radiator, but be sure the cooling system is
cool before you
do it.

Steam and scalding liquids from a hot cooling
system can blow out and burn you badly. They
are under pressure, and if you turn the radiator
pressure cap
-- even a little -- they can come out
at high speed. Never turn the cap when the
cooling system, including the radiator pressure
cap, is hot. Wait for the cooling system and
radiator pressure cap to cool if you ever have to
turn the pressure cap.

Downloaded from www.Manualslib.com manuals search engine How to Add Coolant to the Radiator
INOTICE:
~~
Your engine has a specific radiator fill procedure.
Failure to follow this procedure could cause your
engine to overheat and be severely damaged.
1. You can remove the
radiator pressure cap
when the cooling
system, including the
radiator pressure cap and
upper radiator hose, is
no longer hot. Turn the
pressure cap slowly
counterclockwise until it
first stops. (Don’t press
down while turning the
pressure cap.)
If
you hear a hiss, wait for that to stop. A hiss means
there
is still some pressure left.
2. Then keep turning
the pressure cap, but
now push down
as you
turn it. Remove the
pressure cap.
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol
and it will burn if the engine parts are hot
enough. Don’t spill coolant on
a hot engine.

proper
DEX-COOL@
coolant mixture,
up to the base
of
the filler neck.
If
you see a stream of coolant coming from an air
bleed valve, close
the valve. Otherwise, close the
valves after the radiator is filled.
5. Rinse or wipe any spilled coolant from the engine
and the compartment.
6. Then fill the coolant recovery tank to the
COLD mark.
7. Put the cap back on the coolant recovery tank, but
leave the radiator pressure cap off.
