player, CB radio, mobile telephone, or two-way
radio, make sure that it can be added by
checking with your dealer/retailer. Also, check
federal rules covering mobile radio and
telephone units. If sound equipment can be
added, it is very important to do it properly.
Added sound equipment can interfere with the
operation of your vehicle’s engine, radio, or
other systems, and even damage them. Your
vehicle’s systems can interfere with the
operation of sound equipment that has
been added.
Your vehicle has a feature called Retained

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 332.Anti-Lock Brake System (ABS)
Your vehicle has the Anti-Lock Brake System
(ABS), an advanced electronic braking system that
will help prevent a braking skid.
When you start the engine and 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 the
brake pedal moves a little. This is normal.
If there is a problem
with ABS, this warning
light will stay on.
SeeAnti-Lock Brake
System Warning
Light on page 206.
291

Remember: ABS does not change the time you
need to get your foot up to the brake pedal
or always decrease stopping distance. If you get
too close to the vehicle in front of you, you will not
have time to apply the brakes if that vehicle
suddenly slows or stops. Always leave enough
room up ahead to stop, even though you
have ABS.
Using ABS
Do not pump the brakes. Just hold the brake pedal
down rmly and let anti-lock work for you. You may
hear the anti-lock pump or motor operate, and feel
the brake pedal pulsate, but this is normal.
Braking in Emergencies
With ABS, you can steer and brake at the same
time. In many emergencies, steering can help you
more than even the very best braking.
Traction Control System (TCS)
(CTS)
Your vehicle has a traction control system 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 rear wheels are spinning or
beginning to lose traction. When this happens,
the system brakes the spinning wheel(s) and/or
reduces engine power to limit wheel spin.
You may feel or hear the system working, but this
is normal.
This warning light will
come on to let you
know if there is
a problem with your
traction control system.
SeeTraction Control System (TCS) Warning Light
on page 206. When this warning light is on, the
system will not limit wheel spin. Adjust your driving
accordingly.
293

Traction Control System (TCS)
(CTS-V)
Your vehicle has 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 rear wheels are
spinning or beginning to lose traction. When this
happens, the system brakes the spinning wheel(s)
and/or reduces engine power to limit wheel spin.
You may feel or hear the system working, but this
is normal.
This warning light will
come on to let you
know if there’s a
problem with your
traction control system.
SeeTraction Control System (TCS) Warning Light
on page 206. When this warning light is on, the
system will not limit wheel spin. Adjust your driving
accordingly.The traction control system automatically comes on
whenever you start your vehicle. To limit wheel
spin, especially in slippery road conditions, you
should always leave the system on. But you can
turn the traction control system off if you ever need
to. You should turn the system off if your vehicle
ever gets stuck in sand, mud or snow and rocking
the vehicle is required. Additionally, turning the
traction control system off on some surfaces, such
as deep snow and loose gravel, will assist vehicle
motion at lower speeds. SeeRocking Your Vehicle
to Get It Out on page 321andIf Your Vehicle is
Stuck in Sand, Mud, Ice, or Snow on page 320for
more information. See alsoWinter Driving on
page 316for information on using TCS when
driving in snowy or icy conditions.
You can turn the system
off by pressing the
TC (traction control)
button located on
the steering wheel.
295

Panic Brake Assist
Your vehicle has a panic brake assist system that
monitors the intention of the driver while braking.
If the system senses that the driver has applied
hard/fast pressure to the brake pedal, the system
will generate additional pressure, making it
easier for the driver to maintain brake application.
When this happens the brake pedal will feel
easier to push. Just hold the brake pedal down
rmly and let the system work for you. You
may feel the brakes vibrate, or you may notice
some noise but this is normal. The brakes
will return to normal operation after the brake
pedal has been released.
Steering
Power Steering
If you lose power steering assist because the
engine stops or the system is not functioning,
you can steer but it will take much more effort.
Speed Variable Assist Steering
If your vehicle has this system, it varies the
amount of effort required to steer the vehicle in
relation to the speed of the vehicle.
The amount of steering effort required is less at
slower speeds to make the vehicle more
maneuverable and easier to park. At faster
speeds, the steering effort increases to provide a
sport-like feel to the steering. This provides
maximum control and stability.
If your vehicle seems harder to steer than normal
when parking or driving slowly, there may be a
problem with the system. You will still have power
steering, but steering will be stiffer than normal
at slow speeds. See your dealer for service.
298

A cornering skid is best handled by easing your
foot off the accelerator pedal.
Remember: Any traction control system helps
avoid only the acceleration skid. If your traction
control system is off, then an acceleration skid is
also best handled by easing your foot off the
accelerator pedal.
If your vehicle starts to slide, ease your foot off
the accelerator pedal and quickly steer the
way you want the vehicle to go. If you start
steering quickly enough, your vehicle may
straighten out. Always be ready for a second skid
if it occurs.
Of course, traction is reduced when water, snow,
ice, gravel, or other material is on the road.
For safety, you will want to slow down and adjust
your driving to these conditions. It is important
to slow down on slippery surfaces because
stopping distance will be longer and vehicle control
more limited.
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.
Remember: Any Anti-Lock Brake System (ABS)
helps avoid only the braking skid.
Competitive Driving
See your warranty book before using your vehicle
for competitive driving.
Notice:If you use your vehicle for competitive
driving, the engine may use more oil than it
would with normal use. Low oil levels can
damage the engine. Be sure to check the oil
level often during competitive driving and keep
the level at or near the upper mark that
shows the proper operating range on the
engine oil dipstick. For information on how to
add oil, seeEngine Oil on page 346.
304

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 reections 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.
Driving Through Deep Standing Water
Notice:If you drive too quickly through
deep puddles or standing water, water can
come in through the engine’s air intake
and badly damage the 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.
