If there is a problem with
ABS, this warning light will
stay on. SeeAntilock Brake
System (ABS) Warning
Light on page 3-40.
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 the 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 to each wheel, as
required, faster than any driver could. This can help
you steer around the obstacle while braking hard.
As you brake, the computer keeps receiving updates on
wheel speed and controls braking pressure accordingly.
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 antilock work for you. You might hear the
antilock 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 more than even
the very best braking.
Brake Assist (Except CTS-V)
This vehicle has a Brake Assist feature designed to
assist the driver in stopping or decreasing vehicle speed
in emergency driving conditions. This feature uses the
stability system hydraulic brake control module to
supplement the power brake system under conditions
where the driver has quickly and forcefully applied
the brake pedal in an attempt to quickly stop or slow
down the vehicle. The stability system hydraulic
brake control module increases brake pressure at each
corner of the vehicle until the ABS activates. Minor
brake pedal pulsations or pedal movement during this
time is normal and the driver should continue to
apply the brake pedal as the driving situation dictates
The Brake Assist feature will automatically disengage
when the brake pedal is released or brake pedal
pressure is quickly decreased.
4-5

StabiliTrak®System
The vehicle has an electronic stability control system
called StabiliTrak. It is an advanced computer controlled
system that assists with directional control of the vehicle
in difficult driving conditions.
StabiliTrak activates when the computer senses a
discrepancy between your intended path and the
direction the vehicle is actually traveling. StabiliTrak
selectively applies braking pressure at any one of the
vehicle’s brakes to help steer the vehicle in the direction
which you are steering.
When the system activates, the Traction Control System
(TCS)/StabiliTrak warning light on the instrument panel
cluster ashes. You may also hear a noise or feel
vibration in the brake pedal. This is normal. Continue
to steer the vehicle in the direction you want it to go.
If there is a problem detected with StabiliTrak, a Service
Stability System message displays on the Driver
Information Center (DIC) and the TCS/StabiliTrak
warning light on the instrument panel cluster comes on.
When this message and warning light displays, the
system is not operational. Driving should be adjusted
accordingly. SeeDIC Warnings and Messages on
page 3-58andWarning Lights, Gages, and Indicators
on page 3-30for more information.StabiliTrak comes on automatically whenever the vehicle
is started. The system should be left on to help assist with
directional control of the vehicle. If StabiliTrak needs to
be turned off, press the TC (traction control) on/off button.
SeeTraction Control System (TCS) on page 4-6.
If cruise control is being used when the StabiliTrak
activates, the cruise control will automatically disengage.
When road conditions allow, reengage the cruise control.
SeeCruise Control on page 3-14for more information.
Traction Control System (TCS)
The vehicle has a Traction Control System (TCS) that
limits wheel spin. This is especially useful in slippery
road conditions. On a rear-wheel-drive vehicle, the
system operates if it senses that one or both of the rear
wheels are spinning or beginning to lose traction. On an
All-Wheel-Drive (AWD) vehicle, the system will operate if
it senses that any of the 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.
The system may be heard or felt while it is working, but
this is normal.
The TCS/StabiliTrak
®warning light will ash when the
traction control system is limiting wheel spin.
4-6

The TCS/StabiliTrak
warning light comes on if
there is a problem with
the traction control system.
SeeStabiliTrak
®/Traction Control System (TCS) Warning
Light on page 3-41andStabiliTrak®System on page 4-6.
When the TCS/StabiliTrak warning light is on, the system
will not limit wheel spin. Adjust your driving accordingly.
TCS automatically comes on whenever the vehicle is
started. To limit wheel spin, especially in slippery road
conditions, the system should always be left on, but
it may be necessary to turn the system off if the vehicle
is stuck in sand, mud or snow and rocking the vehicle
is required. Also, turn TCS off while in deep snow or on
loose gravel, to assist vehicle motion at lower speeds.
SeeRocking Your Vehicle to Get It Out on page 4-20for
more information. See alsoWinter Driving on page 4-17
for information on using TCS when driving in snowy
or icy conditions.To turn the system off,
press the TCS/StabiliTrak
button located on the
instrument panel (CTS)
or the steering
wheel (CTS-V).
Press and release the TCS/StabiliTrak button
and the traction control system will turn off and the
TCS/StabiliTrak warning light will come on. Press the
button again to turn the system back on. For information
on turning StabiliTrak off and on, see StabiliTrak System
previously.
Adding non-dealer/non-retailer accessories can affect
your vehicle’s performance. SeeAccessories and
Modifications on page 5-3for more information.

Competitive Driving Mode
To select this optional handling mode, press the
TCS/StabiliTrak button quickly two times and the
STABILITRAK COMPETITVE MODE displays in the
Driver Information Center (DIC). While in the StabiliTrak
Competitive Mode, TCS does not limit wheel spin, and
the TCS/StabiliTrak warning light comes on. Adjust your
driving accordingly.
Press the TCS/StabiliTrak button again, or turn the
ignition to ACC/ACCESSORY and restart the vehicle,
to turn TCS back on and turn the TCS/StabiliTrak
warning light off.
Notice:When traction control is turned off, or
Competitive Driving Mode is active, it is possible to
lose traction. If you attempt to shift with the rear
wheels spinning with a loss of traction, it is possible
to cause damage to the transmission. Do not attempt
to shift when the rear wheels do not have traction.
Damage caused by misuse of the vehicle is not
covered. See the warranty book for additional
information.
Magnetic Ride Control™
With this feature on the CTS-V, the Magnetic Ride
Control system adjusts the ride of the vehicle to Touring
or Sport modes. Magnetic Ride Control monitors the
suspension system to determine the proper system
response.
TOUR:Use for normal city and highway driving.
This setting provides a smooth, soft ride.
SPORT:Use where road conditions or personal
preference demand more control. This setting provides
more “feel”, or response to road conditions.
The setting can be changed at any time. Based on road
conditions, steering wheel angle and the vehicle speed,
the system automatically adjusts to provide the best
handling while providing a smooth ride. The Touring and
Sport modes will feel similar on a smooth road. Select a
new setting whenever driving conditions change.
The Driver Information Center (DIC) briey displays
SUSPENSION MODE TOURING or SUSPENSION
MODE SPORT on vehicle startup or when a new mode
is selected.

Press and release this
button, located in the
center of the instrument
panel, to change modes.
Limited-Slip Rear Axle
Vehicles with a limited-slip rear axle can give more
traction on snow, mud, ice, sand or gravel. It works like
a standard axle most of the time, but when traction
is low, this feature allows the drive wheel with the most
traction to move the vehicle.
All-Wheel Drive (AWD) System
With this feature, the AWD system will automatically
monitor and adjust engine power to the front and
rear wheels for the best traction and handling. If there is
a loss of traction or stability, the AWD system works
with the electronic stability control system to increase
power to the front wheels as necessary.
If the spare tire is on the vehicle, there may be a slight
reduction in performance of the AWD system.
SeeDIC Warnings and Messages on page 3-58for
AWD related DIC messages.
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
Your vehicle has a steering system that 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/retailer for service.
