Anti-Lock Brake System Active Light
LOW
TRACTION
When your anti-lock
system is adjusting
brake pressure to help
avoid a braking
skid, the
“LOW
TRACTION’ light
will come on.
Slippery road conditions will 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
“LOW TRACTION” light also comes on
briefly, as a
bulb check, when the engine is started.
Engine Coolant Temperature Warning
Light
k F- 4ccN
TEMP
This light tells you that
your engine coolant has
overheated or your radiator
cooling fan is not working.
If you have been operating
your vehicle under normal
driving conditions, you
should pull off the road,
stop your vehicle and turn
the engine
off as soon as
possible.
The chapter “Problems on the Road,” in this manual
explains what to do. See “Engine Overheating” in the
Index.

If you get the overheat warning with no sign of steam,
try this for a minute or
so:
1. Turn off your air conditioner.
2. Turn on your heater to full hot at the highest fan
speed and open the window as necessary.
3. Try to keep your engine under load (in a drive gear
where the engine runs slower).
If you no longer have the overheat warning, you can
drive. Just to be safe, drive slower for about ten minutes.
If the warning doesn't come back on, you can drive
normally.
If the warning continues, pull over, stop, and park your
vehicle right away.
If there's still no sign of steam, you can idle the engine
for two or three minutes while you're parked, to see
if the
warning stops.
But then, if you still have the warning,
TURN OFF THE ENGINE AND GET EVERYONE
OUT OF THE VEHICLE until it cools down. When you
decide it's safe to
lift the hood, here's what
you'll see:
(A) Coolant recovery tank
(B) Radiator pressure cap
(C) Electric engine fan
You may decide not to
lift the hood but to get service
help right away.

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
“FULL
HOT” mark.
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.

NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core
and other parts. Use
the recommended coolant.
When the coolant in the coolant recovery tank is at or
above the the
“FULL HOT” 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.

How to Add Coolant to the Radiator
NOTICE:
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
1 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
to the left until it first
stops. (Don't press
down while turning the
pressure cap.)

3. After the engine cools, open the coolant air bleed
valve.
On
the 3100 SF1 V6 (VIN Code M), it is located on
the thermostat bypass tube.
4. Fill the radiator with the proper mix, 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
valve after the radiator is filled.
5. Rinse or wipe any spilled coolant from the engine
and compartment.

6. Then fill the coolant recovery tank to “FULL HOT’’
mark.
