Audio System(s)
Notice:Before adding any sound equipment to
your vehicle, like a tape player, CB radio, mobile
telephone, or two-way radio, make sure that it can
be added by checking with your dealer. 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 may interfere with the operation
of your vehicle’s engine, radio, or other systems,
and even damage them. Your vehicle’s systems may
interfere with the operation of sound equipment
that has been added improperly.
Figure out which audio system is in your vehicle, nd
out what your audio system can do, and how to operate
all of its controls.
Your vehicle has a feature called Retained Accessory
Power (RAP). With RAP, the audio system can be
played even after the ignition is turned off. SeeRetained
Accessory Power (RAP) on page 2-24for more
information.

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. Your brakes may not have time to cool between
hard stops. Your 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 engine ever stops while you are driving, brake
normally but do not pump your brakes. If you do,
the pedal may get harder to push down. If your 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.Anti-Lock Brake System (ABS)
Your vehicle has anti-lock brakes. ABS is an advanced
electronic braking system that will help prevent a
braking skid.
When you start your engine and begin to drive away,
your anti-lock brake system 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 a little. This is normal.
If there is a problem with
the anti-lock brake system,
this warning light will
stay on. SeeAnti-Lock
Brake System Warning
Light on page 3-42.
4-6

Using Anti-Lock
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 anti-lock brakes, 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’s a problem with
your traction control
system.
SeeTraction Control System (TCS) Warning Light on
page 3-43. 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 4-33for more information. See alsoWinter
Driving on page 4-28for 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 in the glove box.
If you press the TC button once, the traction control
system will turn off and the traction control system
warning light will come on. Press the TC button again to
turn the system back on. If you press and hold the
TC button for ve seconds, the StabiliTrak
®system will
turn off. Press the TC button again to turn StabiliTrak®
back on. For more information, seeStabiliTrak®System
on page 4-11.
You can program your steering wheel controls (CTS
only) and/or the buttons on the Base audio system
to turn the TCS on or off. SeeRecongurable Steering
Wheel Controls (SWC) (CTS) on page 3-7and/or
“Congurable Radio Display Keys” underRadio with CD
on page 3-89for programming instructions.
Traction Control
System (TCS) (CTS-V)
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’s
a problem with your traction
control system.
SeeTraction Control System (TCS) Warning Light on
page 3-43. 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.

(traction control) button
located on the steering
wheel.
If you press the TC button once, the traction control
system will turn off and the traction control system
warning light will come on. If you press the TC button
again within ve seconds, the traction control system will
remain off, the warning light will stay on, and the
stability system will enter Competitive Driving Mode.
Competitive Driving will be displayed on the Driver
Information Center (DIC). SeeDIC Warnings and
Messages on page 3-65for more information.Press the TC button again to turn the system back on.
If you press and hold the TC button for ve seconds,
the StabiliTrak
®and Traction Control systems will turn
off. Press the TC button again to turn StabiliTrak®
and Traction Control back on. For more information, see
StabiliTrak®System on page 4-11.
Competitive Driving Mode (CTS-V)
See your warranty book before using your vehicle
for racing or other competitive driving.
Notice:If you use your vehicle for racing or other
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 racing or other 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, see
Engine Oil on page 5-16.
The driver can select this optional handling mode by
pressing the Traction Control button on the steering
wheel twice within ve seconds. COMPETITIVE
DRIVING will be displayed in the DIC. Competitive driving
mode allows the driver to have control of the power
applied to the rear wheels, while the StabiliTrak
®system
helps steer the vehicle by selective brake application.
4-10

If there is a problem detected with StabiliTrak®,a
Service Stability System message will be displayed on
the Driver Information Center. SeeDIC Warnings
and Messages on page 3-65. When this message is
displayed, the system is not operational. Driving should
be adjusted accordingly.
StabiliTrak
®comes on automatically whenever you start
your vehicle. To help assist you with directional
control of the vehicle, you should always leave the
system on. You can turn StabiliTrak
®off if you ever need
to through the TC (traction control) on/off button. See
Traction Control System (TCS) (CTS) on page 4-8
orTraction Control System (TCS) (CTS-V) on page 4-9.
If your vehicle is in cruise control when the StabiliTrak
®
activates, the cruise control will automatically
disengage. When road conditions allow you to safely
use it again, you may reengage the cruise control.
SeeCruise Control (CTS) on page 3-12orCruise
Control (CTS-V) on page 3-16for more information.
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.
4-12

Skidding
In a skid, a driver can lose control of the vehicle.
Defensive drivers avoid most skids by taking reasonable
care suited to existing conditions, and by not overdriving
those conditions. But skids are always possible.
The three types of skids correspond to your vehicle’s
three control systems. In the braking skid, your wheels
are not rolling. In the steering or cornering skid, too much
speed or steering in a curve causes tires to slip and lose
cornering force. And in the acceleration skid, too much
throttle causes the driving wheels to spin.
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 engine braking 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.

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 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. 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. SeeTires
on page 5-54.
