Avoid needless heavy braking. Some people drive
in spurts — heavy acceleration followed by heavy
braking — rather than keeping pace with traffic.
This is a mistake. The brakes may not have time to
cool between hard stops. The brakes will wear out
much faster if you do a lot of heavy braking. If you
keep pace with the traffic and allow realistic
following distances, you will eliminate a lot of
unnecessary braking. That means better braking
and longer brake life.
If your vehicle’s engine ever stops while you are
driving, brake normally but do not pump the
brakes. If you do, the pedal may get harder to
push down. If the engine stops, you will still have
some power brake assist. But you will use it
when you brake. Once the power assist is used
up, it may take longer to stop and the brake pedal
will be harder to push.
Adding non-GM accessories can affect your
vehicle’s performance. SeeAccessories and
Modications on page 308.Anti-Lock Brake System (ABS)
Your vehicle may have the Anti-Lock Brake
System (ABS), an advanced electronic braking
system that will help prevent a braking skid.
If your vehicle has ABS,
this warning light on the
instrument panel will
come on briey when
you start your vehicle.
When you start your engine, or when you begin to
drive away, ABS will check itself. You may hear a
momentary motor or clicking noise while this test is
going on, and you may even notice that your brake
pedal moves or pulses a little. This is normal.
259

Traction Control System (TCS)
Your vehicle may have a Traction Control System
(TCS) that limits wheel spin. This is especially
useful in slippery road conditions. The system
operates only if it senses that one or both of the
front wheels are spinning or beginning to lose
traction. When this happens, the system reduces
engine power and may also upshift the transaxle
to limit wheel spin. Also, the traction control system
activates the appropriate corner brakes to gain
even quicker control to limit wheel spin.
This light, located on the
instrument panel, will
come on when your
Traction Control System
is limiting wheel spin.
You may feel or hear the system working, but this
is normal.
If your vehicle is in cruise control when the
traction control system begins to limit wheel spin,
the cruise control will automatically disengage.When road conditions allow you to safely use it
again, you may re-engage the cruise control. See
Cruise Control on page 171.
The Traction Control System operates in all
transaxle shift lever positions except park or
neutral. But the system can upshift the transaxle
only as high as the shift lever position you’ve
chosen, so you should use the lower gears only
when necessary. SeeAutomatic Transaxle
Operation on page 129.
This light is located on
the instrument panel
cluster.
When the system is on, this light will come on to let
you know if there’s a problem, or if the system has
been turned off.
When this warning light is on, the system will not
limit wheel spin. Adjust your driving accordingly.
262

To limit wheel spin, especially in slippery road
conditions, you should always leave the Traction
Control System on. But you can turn the system off
if you prefer.
To turn the system on or off, press the traction
control button (TC) located under the climate
controls. In order to effectively “rock” the vehicle,
you will need to turn off TCS.
If you press the TC button once, the traction control
system will turn off and the traction control system
warning light will come on. The StabiliTrak
®system
will stay on. Press the TC button again to turn the
system back on. The traction control system
warning light will go off. If you press and hold the
TC button, the StabiliTrak
®system and the traction
control system will turn off. Press the TC button
again to turn StabiliTrak
®and the traction control
system back on. For more information, see
StabiliTrak
®System on page 265.
When you turn the system off, the Traction Control
System warning light will come on and stay on.
If the Traction Control System is limiting wheel spin
when you press the button to turn the system
off, the warning light will come on – but the system
won’t turn off right away. It will wait until there’s
no longer a current need to limit wheel spin.Adding non-GM accessories can affect your
vehicle’s performance. SeeAccessories and
Modications on page 308for more information.
Enhanced Traction System (ETS)
Your vehicle may have an Enhanced Traction
System (ETS) that limits wheel spin. This is
especially useful in slippery road conditions. The
system operates only if it senses that one or
both of the front wheels are spinning or beginning
to lose traction. When this happens, the system
reduces engine power and may also upshift
the transaxle to limit wheel spin.
This light, located on
the instrument panel,
will come on when your
Enhanced Traction
System is limiting
wheel spin.
You may feel or hear the system working, but this
is normal.

Steering
Electric Power Steering
If your vehicle has the electric power steering
system and the engine stalls while you are driving,
the power steering assist system will continue to
operate until you are able to stop your vehicle. If
you lose power steering assist because the electric
power steering system is not functioning, you can
steer, but it will take more effort.
If you turn the steering wheel in either direction
several times until it stops, or hold the steering
wheel in the stopped position for an extended
amount of time, you may notice a reduced amount
of power steering assist. The normal amount of
power steering assist should return shortly after a
few normal steering movements.
The electric power steering system does not
require regular maintenance. If you suspect
steering system problems, contact your dealer for
service repairs. SeeDIC Warnings and Messages
on page 212.
Hydraulic Power Steering
If your vehicle has the hydraulic power steering
system and you lose power steering assist
because the engine stops or the power steering
system is not functioning, you can steer, but it will
take much more effort.
Steering Tips
It is important to take curves at a reasonable
speed.
A lot of the “driver lost control” accidents
mentioned on the news happen on curves.
Here is why:
Experienced driver or beginner, each of us is
subject to the same laws of physics when driving on
curves. The traction of the tires against the road
surface makes it possible for the vehicle to change
its path when you turn the front wheels. If there is
no traction, inertia will keep the vehicle going in the
same direction. If you have ever tried to steer a
vehicle on wet ice, you will understand this.

Driving Through Deep Standing Water
Notice:If you drive too quickly through
deep puddles or standing water, water can
come in through your engine’s air intake and
badly damage your engine. Never drive through
water that is slightly lower than the underbody
of your vehicle. If you cannot avoid deep
puddles or standing water, drive through them
very slowly.
Driving Through Flowing Water
{CAUTION:
Flowing or rushing water creates strong
forces. If you try to drive through owing
water, as you might at a low water
crossing, your vehicle can be carried away.
CAUTION: (Continued)
CAUTION: (Continued)
As little as six inches of owing water can
carry away a smaller vehicle. If this
happens, you and other vehicle occupants
could drown. Do not ignore police
warning signs, and otherwise be very
cautious about trying to drive through
owing water.
Some Other Rainy Weather Tips
Besides slowing down, allow some extra
following distance. And be especially careful
when you pass another vehicle. Allow yourself
more clear room ahead, and be prepared to
have your view restricted by road spray.
Have good tires with proper tread depth. See
Tires on page 370.
276

Once you are moving on the freeway, make
certain you allow a reasonable following distance.
Expect to move slightly slower at night.
When you want to leave the freeway, move to the
proper lane well in advance. If you miss your
exit, do not, under any circumstances, stop and
back up. Drive on to the next exit.
The exit ramp can be curved, sometimes quite
sharply. The exit speed is usually posted. Reduce
your speed according to your speedometer, not
to your sense of motion. After driving for any
distance at higher speeds, you may tend to think
you are going slower than you actually are.
Before Leaving on a Long Trip
Make sure you are ready. Try to be well rested. If
you must start when you are not fresh — such
as after a day’s work — do not plan to make too
many miles that rst part of the journey. Wear
comfortable clothing and shoes you can easily
drive in.Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it is ready to go. If it
needs service, have it done before starting out. Of
course, you will nd experienced and able
service experts in GM dealerships all across North
America. They will be ready and willing to help
if you need it.
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 inated 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.
Hill and Mountain Roads
Driving on steep hills or mountains is different
from driving in at or rolling terrain.
280

If you drive regularly in steep country, or if you are
planning to visit there, here are some tips that
can make your trips safer and more enjoyable.
Keep your vehicle in good shape. Check
all uid levels and also the brakes, tires,
cooling system, and transaxle. These parts
can work hard on mountain roads.
{CAUTION:
If you do not shift down, your brakes
could get so hot that they would not work
well. You would then have poor braking or
even none going down a hill. You could
crash. Shift down to let your engine assist
your brakes on a steep downhill slope.
{CAUTION:
Coasting downhill in NEUTRAL (N) or with
the ignition off is dangerous. Your brakes
will have to do all the work of slowing
down. They could get so hot that they
would not work well. You would then have
poor braking or even none going down a
hill. You could crash. Always have your
engine running and your vehicle in gear
when you go downhill.
Know how to go down hills. The most important
thing to know is this: let your engine do some of
the slowing down. Shift to a lower gear when
you go down a steep or long hill.
Know how to go uphill. Drive in the highest gear
possible.
