Engine Coolant Temperature Gage
Your vehicle has an
engine coolant
temperature gage.
With the ignition turned
to ON, 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.
SeeEngine Overheating on page 271.
Tire Pressure Light
This light comes on
briefly when you turn
the ignition to RUN.
This light will also come on when one or more of
your tires are significantly underinflated.
Stop and check your tires as soon as it is safe to
do so. If underinflated, inflate to the proper
pressure. SeeTires on page 303for more
information.
This light will flash for about 75 seconds and then
stay on if a problem is detected with the Tire
Pressure Monitor system.
SeeTire Pressure Monitor System on page 312
for more information.

Let us say the road is wet and you are driving
safely. Suddenly, an animal jumps out in front of
you. You slam on the brakes and continue braking.
Here is what happens with ABS:
A computer senses that wheels are slowing down.
If one of the wheels is about to stop rolling, the
computer will separately work the brakes at
each wheel.ABS can change the brake pressure faster than
any driver could. The computer is programmed
to make the most of available tire and road
conditions. This can help you steer around the
obstacle while braking hard.
As you brake, your computer keeps receiving
updates on wheel speed and controls braking
pressure accordingly.

While driving on a surface with reduced traction, try
your best to avoid sudden steering, acceleration, or
braking, including reducing vehicle speed by
shifting to a lower gear. Any sudden changes could
cause the tires to slide. You may not realize the
surface is slippery until your vehicle is skidding.
Learn to recognize warning clues — such as
enough water, ice, or packed snow on the road to
make a mirrored surface — and slow down when
you have any doubt.
If you have the Anti-Lock Brake System (ABS),
remember: It helps avoid only the braking
skid. If you do not have ABS, then in a braking
skid, where the wheels are no longer rolling,
release enough pressure on the brakes to get the
wheels rolling again. This restores steering
control. Push the brake pedal down steadily when
you have to stop suddenly. As long as the
wheels are rolling, you will have steering control.Driving at Night
Night driving is more dangerous than day driving.
One reason is that some drivers are likely to
be impaired — by alcohol or drugs, with night
vision problems, or by fatigue.
Here are some tips on night driving.
•Drive defensively.
•Do not drink and drive.
•Adjust the inside rearview mirror to reduce the
glare from headlamps behind you.
•Since you cannot see as well, you may need
to slow down and keep more space between
you and other vehicles.
•Slow down, especially on higher speed roads.
Your vehicle’s headlamps can light up only so
much road ahead.
•In remote areas, watch for animals.
•If you are tired, pull off the road in a safe
place and rest.
220

{CAUTION:
Wet brakes can cause accidents. They
may not work as well in a quick stop and
may cause pulling to one side. You could
lose control of the vehicle.
After driving through a large puddle of
water or a car wash, apply the brake pedal
lightly until the brakes work normally.
Driving too fast through large water puddles or
even going through some car washes can cause
problems, too. The water may affect your
brakes. Try to avoid puddles. But if you cannot, try
to slow down before you hit them.
Hydroplaning
Hydroplaning is dangerous. So much water can
build up under your tires that they can actually ride
on the water. This can happen if the road is wet
enough and you are going fast enough. When your
vehicle is hydroplaning, it has little or no contact
with the road.
Hydroplaning does not happen often. But it can if
your tires do not have much tread or if the
pressure in one or more is low. It can happen if a
lot of water is standing on the road. If you can
see reflections from trees, telephone poles,
or other vehicles, and raindrops dimple the water’s
surface, there could be hydroplaning.
Hydroplaning usually happens at higher speeds.
There just is not a hard and fast rule about
hydroplaning. The best advice is to slow down
when it is raining.

Here are some things you can check before a trip:
•Windshield Washer Fluid:Is the reservoir
full? Are all windows clean inside and outside?
•Wiper Blades:Are they in good shape?
•Fuel, Engine Oil, Other Fluids:Have you
checked all levels?
•Lamps:Are they all working? Are the lenses
clean?
•Tires:They are vitally important to a safe,
trouble-free trip. Is the tread good enough
for long-distance driving? Are the tires
all inflated to the recommended pressure?
•Weather Forecasts:What is the weather
outlook along your route? Should you
delay your trip a short time to avoid a major
storm system?
•Maps:Do you have up-to-date maps?
Highway Hypnosis
Is there actually such a condition as highway
hypnosis? Or is it just plain falling asleep at the
wheel? Call it highway hypnosis, lack of
awareness, or whatever.
There is something about an easy stretch of road
with the same scenery, along with the hum of the
tires on the road, the drone of the engine, and the
rush of the wind against the vehicle that can make
you sleepy. Do not let it happen to you! If it does,
your vehicle can leave the road in less than a
second, and you could crash and be injured.
What can you do about highway hypnosis?
First, be aware that it can happen.
Then here are some tips:
•Make sure your vehicle is well ventilated, with
a comfortably cool interior.
•Keep your eyes moving. Scan the road ahead
and to the sides. Check your rearview mirrors
and your instruments frequently.
•If you get sleepy, pull off the road into a rest,
service, or parking area and take a nap, get
some exercise, or both. For safety, treat
drowsiness on the highway as an emergency.

Tire and Loading Information LabelA vehicle specific tire and loading information label
shows the seating capacity and the maximum
load your vehicle can properly carry. This label
also contains your vehicle’s original equipment tire
size and the recommended tire inflation pressure.
For more information on tires and inflation see
Tires on page 303andInflation - Tire Pressure on
page 311. The tire and loading information label
is attached inside the glove box of the five door
hatchback model. The tire and loading information
label for the wagon is attached to the vehicle’s
center pillar, below the driver’s door latch.
There is also important loading information on the
Certification label. It tells you the Gross Vehicle
Weight Rating (GVWR) and the Gross Axle Weight
Rating (GAWR) for the front and rear axle; see
“Certification Label” later in this section.

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 GM Warranty booklet
for details. For additional information refer to
the tire manufacturer’s booklet included with your
vehicle.
{CAUTION:
Poorly maintained and improperly used
tires are dangerous.
Overloading your vehicle’s tires can
cause overheating as a result of too
much friction. You could have an
air-out and a serious accident. See
Loading Your Vehicle on page 236.
CAUTION: (Continued)
CAUTION: (Continued)

Underinated tires pose the same
danger as overloaded tires. The
resulting accident could cause serious
injury. Check all tires frequently to
maintain the recommended pressure.
Tire pressure should be checked when
your vehicle’s tires are cold. See
Inflation - Tire Pressure on page 311.
Overinated tires are more likely to be
cut, punctured, or broken by a sudden
impact — such as when you hit a
pothole. Keep tires at the
recommended pressure.
Worn, old tires can cause accidents.
If the tire’s tread is badly worn, or if
your vehicle’s tires have been
damaged, replace them.
303

(D) Tire Ply Material:The type of cord and
number of plies in the sidewall and under the tread.
(E) Uniform Tire Quality Grading (UTQG):
Tire manufacturers are required to grade
tires based on three performance factors:
treadwear, traction and temperature resistance.
For more information seeUniform Tire Quality
Grading on page 320.
(F) Maximum Cold Ination Load Limit:
Maximum load that can be carried and the
maximum pressure needed to support that load.
For information on recommended tire pressure
seeInflation - Tire Pressure on page 311
andLoading Your Vehicle on page 236.
(A) Temporary Use Only:The compact spare
tire or temporary use tire has a tread life of
approximately 3,000 miles (5 000 km) and should
not be driven at speeds over 65 mph (105 km/h).
The compact spare tire is for emergency use when
a regular road tire has lost air and gone flat.
SeeCompact Spare Tire on page 334andIf a
Tire Goes Flat on page 324.
