9-30 Driving and Operating
To use the DSC feature using the
Tap Shift controls:
1. Move the shift lever tothe right from D (Drive) to
M (Manual Mode).
2. Tap the left control to downshift, and the right control to upshift.
3. To return to sport mode, hold the right upshift control briefly,
or hold the shift lever forward
briefly, or return the shift lever to
D (Drive).
With the shift lever in D (Drive), the
tap shift controls will activate a
temporary tap manual shift mode,
allowing the transmission to be
manually shifted. Automatic shifts
return after no manual shifts have
been done for seven to 10 second.
The temporary tap mode can also
be deactivated by holding the right
upshift control briefly.
The tachometer display indicates
which gear the vehicle is in. The
number indicates the requested
gear range when moving the shift
lever forward or rearward.
CTS-V vehicles use tracer lights
around the outside of the
tachometer as a performance
upshift light. These tracers flash to
indicate when to shift to the next
higher gear to avoid the engine
speed limit. See Tachometer on
page 5‑13 for more information. While using the DSC feature, the
vehicle will have firmer, quicker
shifting. You can use this for sport
driving or when climbing or
descending hills, to stay in gear
longer, or to downshift for more
power or engine braking.
The transmission will only allow
you to shift into gears appropriate
for the vehicle speed and engine
revolutions per minute (RPM). The
transmission will not automatically
shift to the next lower gear if the
engine rpm is too high, nor to the
next higher gear when the maximum
engine rpm is reached.
If shifting is prevented for any
reason, the currently selected gear
will flash multiple times, indicating
that the transmission has not shifted
gears.

draining the battery, do not operate
the EPB too often without the
engine running.
The system has two warning lights
and five Driver Information Center
(DIC) messages. SeeBrake System
Warning Light on page 5‑22 and
Driver Information Center (DIC) on
page 5‑27 for more information. In
case of insufficient electrical power,
the EPB cannot be applied or
released.
EPB Apply
The EPB can be applied any time
the vehicle is stopped. The EPB is
applied by momentarily lifting up on
the EPB switch. Once fully applied,
the BRAKE light will be on, and the
DIC message PARK BRAKE SET
will be displayed. While the brake is
being applied, the status light will
flash until full apply is reached.
If the light does not come on,
or remains flashing, you need to
have the vehicle serviced. Do not
drive the vehicle if the BRAKE light is flashing. See your dealer. See
Brake System Warning Light on
page 5‑22
for more information.
If the EPB is applied while the

RELEASE PARK BRAKE SWITCH
will be displayed. The vehicle will
decelerate as long as the switch is
held in the up position. Releasing
the EPB switch during the
deceleration will release the parking
brake. If the switch is held in the up
position until the vehicle comes to a
stop, the EPB will remain applied.
If the BRAKE light is on, either the
EPB is applied, or there is a failure
in the hydraulic brake system.
If this light is flashing continuously,
the EPB is only partially applied or
released, or there is a problem with
the EPB. The DIC message
SERVICE PARK BRAKE will be
displayed. If this light is flashing
continuously, release the EPB, and attempt to apply it again. If this light
continues to flash, do not drive the
vehicle. See your dealer.
If the yellow light is on, the EPB has
detected an error in another system
and is operating with reduced
functionality. To apply the EPB when
this light is on, lift up on the EPB
switch and hold it in the up position.
Full application of the parking brake
by the EPB system may take a
longer period of time than normal
when this light is on. Continue to
hold the switch until the BRAKE
light remains on. If the yellow light is
on, see your dealer.
If the EPB fails to apply, the rear
wheels should be blocked to
prevent vehicle movement.

Notice:Driving with the parking
brake on can overheat the brake
system and cause premature
wear or damage to brake system
parts. Make sure that the parking
brake is fully released and the red
brake warning light is off before
driving.Automatic EPB Release
The EPB will automatically release if
the vehicle is running, placed into
gear, and an attempt is made to
drive away. Avoid rapid acceleration
when the EPB is applied, to
preserve park brake lining life.
The EPB can also be used to
prevent roll back for vehicles with a
manual transmission taking off on a
hill. In a situation where no roll back
is desired, an applied EPB will allow
both feet to be used for the clutch
and accelerator pedals in
preparation for starting the vehicle
moving in the intended direction.
In this situation, perform the normal
clutch and/or accelerator actions
required to begin moving the
vehicle. There is no need to push
the switch to release the EPB.
If you are towing a trailer and
parking on a hill, see Driving
Characteristics and Towing Tips on
page 9‑56 for more information.
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 pulsation 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.

9-38 Driving and Operating
Ride Control Systems
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 light flashes
when the traction control system is
limiting wheel spin.
The TCS/StabiliTrak light comes on
and the SERVICE TRACTION
CONTROL message will be
displayed in the DIC if there is a
problem with the traction control
system. When the TCS/StabiliTrak
light is on, the system will not limit
wheel spin. Adjust your driving
accordingly. SeeTraction Control
System (TCS)/StabiliTrak
®Light on
page 5‑24 for more information.
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. See
If the Vehicle Is Stuck
on page 9‑11 for more information.
See Winter Driving on page 9‑9 for
information on using TCS when
driving in snowy or icy conditions.
The TCS/StabiliTrak button is
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
TRACTION CONTROL OFF will
be displayed in the DIC. Press the

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
system senses a discrepancy
between the 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, this
warning light flashes on the
instrument panel. A noise may be
heard or a vibration may be felt in
the brake pedal. This is normal.
Continue to steer the vehicle in the
intended direction.
If there is a problem detected with
StabiliTrak, SERVICE
STABILITRAK displays on the
Driver Information Center (DIC) and
the TCS/StabiliTrak warning light
comes on the instrument panel
cluster. When this message and
light displays, the system is not
operational. Driving should be adjusted accordingly. See
Driver
Information Center (DIC) on
page 5‑27 and Messages and
Traction Control System (TCS)/
StabiliTrak
®Light on page 5‑24 for
more information.
The TCS/StabiliTrak button is
located on the instrument panel
(CTS) or the steering
wheel (CTS-V).
StabiliTrak comes on automatically
whenever the vehicle is started. The
system should be left on to help

more effort is required to turn the
steering wheel. 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 drive wheels
spinning with a loss of traction, it
is possible to cause damage to
the transmission. Do not attempt
to shift when the drive 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
Tour 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 Tour and Sport
modes will feel similar on a smooth
road. Select a new setting whenever
driving conditions change.

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. When
traction is low, this feature allows
the drive wheel with the most
traction to move the vehicle. The
limited-slip rear axle also gives the
driver enhanced control when
cornering hard or completing a
maneuver, such as a lane change.
Cruise Control
{WARNING
Cruise control can be dangerous
where you cannot drive safely at
a steady speed. So, do not use
the cruise control on winding
roads or in heavy traffic.
Cruise control can be dangerous
on slippery roads. On such roads,
fast changes in tire traction can
cause excessive wheel slip, and
you could lose control. Do not use
cruise control on slippery roads.
With cruise control, a speed of
about 40 km/h (25 mph) or more can
be maintained without keeping your
foot on the accelerator. Cruise
control does not work at speeds
below about 40 km/h (25 mph).
When the brakes are applied, the
cruise control turns off. If the vehicle has the Stabilitrak
®
system and begins to limit wheel
spin while you are using cruise
control, the cruise control will
automatically disengage. See
StabiliTrak
®System on page 9‑39.
When road conditions allow you to
safely use it again, the cruise
control can be turned back on.

Object Detection
Systems
Ultrasonic Parking Assist
If available, the Ultrasonic Rear
Parking Assist (URPA) system
assists the driver with parking
and avoiding objects while in
R (Reverse). URPA operates at
speeds less than 8 km/h (5 mph).
The sensors on the rear bumper
detect objects up to 2.5 m (8 ft)
behind the vehicle, and at least
25 cm (10 in) off the ground.
{WARNING
The URPA system does not
detect pedestrians, bicyclists,
animals, or any other objects
located below the bumper or that
are too close or too far from the
vehicle. To prevent injury, death,
or vehicle damage, even with(Continued)
WARNING (Continued)
URPA, always check behind the
vehicle and check all mirrors
before backing.
How the System Works
URPA comes on automatically
when the shift lever is moved into
R (Reverse). A single tone sounds
to indicate the system is working.
URPA operates only at speeds less
than 8 km/h (5 mph).
An obstacle is indicated by audible
beeps. The interval between the
beeps becomes shorter as the
vehicle gets closer to the obstacle.
When the distance is less than
30 cm (12 in), the beeping is a
continuous tone for five seconds.
To be detected, objects must be at
least 25 cm (10 in) off the ground
and below trunk or liftgate level.
Objects must also be within 2.5 m (8 ft) of the rear bumper. This
distance may be less during warmer
or humid weather.
Turning the System On and Off
The system can be disabled through
the Driver Information Center (DIC).
See
“Parking Assist” underDriver
Information Center (DIC) on
page 5‑27 for more information.
URPA defaults to the on setting
each time the vehicle is started.
When the System Does Not
Seem to Work Properly
The following messages may be
displayed on the DIC:
PARKING ASSIST OFF: This
message occurs if the driver
disables the system or if vehicle is
driven above 8 km/h (5 mph) in
R (Reverse).
SERVICE PARKING ASSIST: If
this message occurs, take the
vehicle to your dealer to repair the
system.
