This light should come on
briefly as you start the
engine. If the light doesn’t
come
on then, have it fixed
so it will be ready to warn
you if there’s a problem.
Engine Coolant Temperature Gage
f
This gage shows the engine
coolant temperature. If the
gage pointer moves into the
shaded area, your engine
is
too hot!
If it stays on, or comes on and the DIC shows a
SERVICE TRACTION SYSTEM message when you’re
driving, there’s a problem with your TCS system and
your vehicle needs service. When this light is on, the
system will not limit wheel spin. Adjust your driving
accordingly. If the driver turns
off the Traction Control
System by pressing the button
on the console, the TCS
system light will come on and the TRACTION
SYSTEM
OFF message will show on the DIC. This
means that your engine coolant has overheated.
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.
(The larger tic marks are in increments of
30 O below
220°F (104°C) and in increments of 10 O above
220 OF (104”C).)
In “Problems on the Road,” this manual shows what to
do. See “Engine Overheating” in the Index.

message on the Driver Information Center.
Overheated Engine Protection
Operating
Mode
Should a low coolant condition exist and the messages
COOLANT OVERTEMP and REDUCED ENGINE
POWER
are displayed, along with the CHECK
ENGINE light, an overheat protection mode which alternates firing groups of four cylinders helps prevent
engine damage. In this mode, you will notice a loss in
power and engine performance. This operating mode allows your vehicle to be driven to a safe place in an
emergency; you may drive up to
50 miles (80 km).
NOTICE:
After driving in the overheated engine protection
operating mode, to avoid engine damage, allow
the engine to cool before attempting any repair.
The engine
oil will be severely degraded. Repair
the cause of coolant
loss, change the oil and reset
the oil life monitor. See “Engine Oil, When to
Change” in the Index.

COLD 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.
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.
1 NOTICE:
Engine damage if you keep running your engine
without coolant isn’t covered by your warranty.
See “Overheated Engine Protection Operating
Mode” in the Index.
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.

When to Check Lubricant
Refer to the Maintenance Schedule to determine how
often to check the lubricant. See “Periodic Maintenance
Inspections” 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
To add lubricant when the level is low, use Axle
Lubricant (GM
Part No. 12345977) or SAE 8OW-90
GL-5 gear lubricant. 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) or SAE 8OW-90 GL-5
gear lubricant.
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-COOL6 extended life coolant.

The following explains your cooling system and how to
add coolant when it is low.
If you have a problem with
engine overheating, see “Engine Overheating” in
the Index.
