This gage shows the engine
coolant temperature. If the
gage pointer moves into
the red area, your engine
is approaching an
overheating condition.
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 section shows what to
do. See “Engine Overheating,’’
in the Index.
Low Coolant Light ( 5.7L V8 Engine)
This warning light should
come on briefly while you
are starting your engine. If
the light doesn’t come on,
have it remired. Your
vehicle is equipped with
a low coolant indicator
that
is designed to detect when the coolant level drops
below the set limit.
If the low coolant level sensor (on
the radiator) detects that the level drops while the engine
is running, the low coolant indicator will light and
remain lit for five minutes or until the ignition switch
is turned to
OFF. Check the coolant level and add
coolant as needed.
The low coolant light might stay on after filling the
radiator. Turn the ignition switch to the
OW position,
then restart the engine to verify that the low coolant
light goes out. See “Engine Coolant” in the Index.
NOTICE:
Driving with the low coolant light on could
cause your vehicle to overheat. See “Engine Overheating’’ in the Index. Your vehicle could
be damaged, and it wouldn’t be covered by
your warranty.

Bi-Level Heating
You may want to use bi-level heating on cool, but sunny
days. This setting directs cool air toward your body and
warmer air toward your feet.
1. Turn the air control knob to BI-LEVEL.
2. Turn the temperature control knob to a
comfortable setting.
3. Turn the fan control knob to the desired speed. Adjust the direction of airflow by moving the louvered vents.
Your vehicle’s flow-through ventilation system supplies outside
air into the vehicle when it is moving. Outside air
will also enter the vehicle when the blower fan is running.
For mild outside temperatures when little heating or
cooling
is needed, you can still direct outside air through
your vehicle.
1. Turn the air control knob to VENT.
2. Turn the temperature control knob to a
comfortable setting.
3. Turn the fan control knob to the desired speed.

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.
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.

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 cooling 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 FULL COLD, add a
50/50 mixture of clean
water (preferably distilled) and DEX-COOL@ engine
coolant
at the coolant recovery tank. (See “Engine
Coolant”
in the Index for more information.)

6. Put the cap back on the coolant recovery tank, but
leave the radiator pressure cap
off.
7. Start the engine and let it run until you can feel the
upper radiator hose getting hot. Watch out for the
engine cooling fans.
8. By this time, the coolant level inside the radiator
filler neck may be lower.
If the level is lower, add
more
of the proper DEX-COOL@ coolant mixture
through the filler neck until the level reaches the
base of the filler neck.

proper level. It’s unusual
for a tire to “blow out” while you’re driving,
especially if you maintain your tires properly.
If air goes
out of a tire, it’s much more likely to leak out slowly.
But if you should ever have
a “blowout,” here are a few
tips about what to expect and what to do:
If a front tire fails, the flat tire will create a drag that
pulls the vehicle toward that side. Take your foot
off the
accelerator pedal and grip the steering wheel firmly.
Steer to maintain lane position, and then gently brake to
a stop well out of the traffic lane.
A rear blowout, particularly on a curve, acts much like a
skid and may require the same correction you’d use in a
skid. In any rear blowout, remove your foot from the
accelerator pedal. Get the vehicle under control
by
steering the way you want the vehicle to go. It may be
very bumpy and noisy, but you can still steer. Gently
brake to a stop
-- well off the road if possible.
If a tire goes flat, the next part shows how to use your
jacking equipment to change
a flat tire safely.

When to Check and Change Lubricant
Refer to the Maintenance Schedule to determine how
often to check the lubricant and when to change
it.
See “Scheduled Maintenance Services” in the Index.
How to Check Lubricant
If the level is below the bottom of the filler plug hole,
you’ll need to add some lubricant. Add enough lubricant
to raise the level to the bottom of the filler plug hole.
What to Use
Standard Differential
Use Axle Lubricant (GM Part No. 12345977) or SAE
80W-90 GL-5 gear lubricant.
Limited-Slip Differential
To add lubricant when the level is low, use Axle
Lubricant (GM
Part No. 12345977). To completely refill
after draining, add
4 ounces (1 18 ml) of Limited-Slip
Differential Lubricant Additive
(GM Part No. 1052358).
Then fill to the bottom of the filler plug hole with Axle
Lubricant (GM
Part No. 12345977).
Engine Coolant
The cooling s stem in your vehicle is filled with
DEX-COOL engine coolant. This coolant is designed
to remain in your vehicle for
5 years or 150,000 miles
(240
000 km) whichever occurs first, if you add only
DEX-COOL’ extended life coolant.
