Low Traction Light (Option)
If your vehicle has the
traction control system,
there will be a LOW
TRACTION light on the
instrument panel.
When your traction control system is limiting wheel
spin, the LOW TRACTION light will come on. Slippery
road conditions may exist if this light comes on, so
adjust your driving accordingly. The light will come on
and stay on for four seconds when your anti
-lock system
adjusts brake pressure for less than four seconds or
when your traction control system limits wheel spin for
less than four seconds. Otherwise, the light will go out
as soon as the anti
-lock system stops adjusting brake
pressure or the traction control system stops limiting
wheel spin.
The LOW TRACTION light also comes on briefly, as a
bulb check, when the engine is started. If the light
doesn't come on then, have it fixed so it will be there to
tell you when the system is active.
Engine Coolant Temperature
Warning Light
This light will come on
when your engine gets
too hot.
If this light comes on, it 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.
In ªProblems on the Road,º this manual shows what
to do. See ªEngine Overheatingº in the Index.

2-94Engine Coolant Temperature Gage
United States Canada
This gage shows the engine coolant temperature. If the
gage pointer moves into the red area, your engine is
too hot!
It 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.
In ªProblems on the Road,º this manual shows you what
to do. See ªEngine Overheatingº in the Index.
Low Coolant Warning Light
United States Canada
If this light comes on, your system is low on coolant and
the engine may overheat.
See ªEngine Coolantº in the Index and have your
vehicle serviced as soon as possible.

Towing Your Vehicle
CAUTION:
To help avoid serious personal injury to you
or others:

Never let passengers ride in a vehicle that is
being towed.

Never tow faster than safe or posted speeds.

Never tow with damaged parts not
fully secured.

Never get under your vehicle after it has
been lifted by the tow truck.

Always secure the vehicle on each side with
separate safety chains when towing it.

Use only the correct hooks.
NOTICE:
Use the proper towing equipment to avoid
damage to the bumper, fascia or fog lamp areas
of the vehicle.
With current trends in automotive styles and design, it is
essential that the correct towing equipment is used to
tow a vehicle. Your vehicle can be towed with wheel
-lift
or car
-carrier equipment. Don't have you vehicle towed
on the drive wheels unless you must. If the vehicle must
be towed on the drive wheels, do not tow the vehicle
more than 500 cumulative miles (800 km) or exceed
50 mph (80 km/h). If these limitations must be
exceeded, then the drive wheels have to be supported on
a dolly.
Consult your dealer or a professional towing service if
you need to have your vehicle towed. See ªRoadside
Assistanceº in the Index.
Engine Overheating
You will find a coolant temperature gage on your
vehicle's instrument panel. See ªEngine Coolant
Temperature Gageº in the Index. You also have a low
coolant level light on your instrument panel. See ªLow
Coolant Lightº in the Index.

NOTICE:
When adding coolant, it is important that you use
only DEX
-COOL
(silicate-free) coolant.
If coolant other than DEX-COOL is added to the
system, premature engine, heater core or
radiator corrosion may result. In addition, the
engine coolant will require change sooner
-- at
30,000 miles (50 000 km) or 24 months,
whichever occurs first. Damage caused by the use
of coolant other than DEX
-COOL
is not
covered by your new vehicle 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 or above the FULL COLD mark, add a 50/50
mixture of clean, drinkable water and DEX
-COOL

engine coolant at the coolant recovery tank. (See
ªEngine Coolantº in the Index for more information.)
CAUTION:
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 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 50/50 mixture of clean, drinkable water and
DEX
-COOL
coolant.

3. After adding fluid, recheck the fluid level as
described under ªHow to Check.º
4. When the correct fluid level is obtained, push the
dipstick back in all the way.
Radiator Pressure Cap
NOTICE:
Your radiator cap is a 15 psi (105 kPa)
pressure
-type cap and must be tightly installed to
prevent coolant loss and possible engine damage
from overheating. Be sure the arrows on the cap
line up with the overflow tube on the radiator
filler neck.
When you replace your radiator pressure cap, a GM cap
is recommended.
Thermostat
Engine coolant temperature is controlled by a thermostat
in the engine coolant system. The thermostat stops the
flow of coolant through the radiator until the coolant
reaches a preset temperature.
When you replace your thermostat, a GM thermostat
is recommended.
Engine Coolant
The cooling system 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.
The following explains your cooling system and how to
add coolant when it is low. If you have a problem with
engine overheating, see ªEngine Overheatingº in
the Index.

4. While holding the wiper arm away from the glass,
push the release clip from under the blade
connecting point and pull the blade assembly down
toward the glass to remove it from the wiper arm.
5. Push the new wiper blade securely on the wiper arm
until you hear the release clip ªclickº into place.
Tires
Your new vehicle comes with high-quality tires made by
a leading tire manufacturer. If you ever have questions
about your tire warranty and where to obtain service, see
your Chevrolet Warranty booklet for details.
CAUTION:
Poorly maintained and improperly used tires
are dangerous.

Overloading your tires can cause
overheating as a result of too much friction.
You could have an air
-out and a serious
accident. See ªLoading Your Vehicleº in
the Index.
