.Pay attention to special road
signs (falling rocks area, winding
roads, long grades, passing or
no-passing zones) and take
appropriate action.
Winter Driving
Driving on Snow or Ice
Drive carefully when there is snow
or ice between the tires and the
road, creating less traction or grip.
Wet ice can occur at about 0°C
(32°F) when freezing rain begins to
fall, resulting in even less traction.
Avoid driving on wet ice or in
freezing rain until roads can be
treated with salt or sand.Drive with caution, whatever the
condition. Accelerate gently so
traction is not lost. Accelerating too
quickly causes the wheels to spin
and makes the surface under the
tires slick, so there is even less
traction.
Try not to break the fragile traction.
If you accelerate too fast, the drive
wheels will spin and polish the
surface under the tires even more.
The
Antilock Brake System (ABS)
on page 9‑33 improves vehicle
stability during hard stops on
slippery roads, but apply the brakes
sooner than when on dry pavement. Allow greater following distance on
any slippery road and watch for
slippery spots. Icy patches can
occur on otherwise clear roads in
shaded areas. The surface of a
curve or an overpass can remain icy
when the surrounding roads are
clear. Avoid sudden steering
maneuvers and braking while
on ice.
Turn off cruise control, if equipped,
on slippery surfaces.

If the Vehicle Is Stuck
Slowly and cautiously spin the
wheels to free the vehicle when
stuck in sand, mud, ice, or snow.
If stuck too severely for the traction
system to free the vehicle, turn the
traction system off and use the
rocking method.
{WARNING
If the vehicle's tires spin at high
speed, they can explode, and you
or others could be injured. The
vehicle can overheat, causing an
engine compartment fire or other
damage. Spin the wheels as little
as possible and avoid going
above 55 km/h (35 mph).
For information about using tire
chains on the vehicle, see Tire
Chains on page 10‑83.
Rocking the Vehicle to Get
it Out
Turn the steering wheel left and
right to clear the area around the
front wheels. Turn off any traction
system. Shift back and forth
between R (Reverse) and a forward
gear, or with a manual transmission,
between 1 (First) or 2 (Second) and
R (Reverse), spinning the wheels as
little as possible. To prevent
transmission wear, wait until the
wheels stop spinning before shifting
gears. Release the accelerator
pedal while shifting, and press
lightly on the accelerator pedal
when the transmission is in gear. Slowly spinning the wheels in the
forward and reverse directions
causes a rocking motion that could
free the vehicle. If that does not get
the vehicle out after a few tries, it
might need to be towed out. If the
vehicle does need to be towed out,
see
Towing the Vehicle on
page 10‑108.
Vehicle Load Limits
It is very important to know how
much weight the vehicle can
carry. This weight is called the
vehicle capacity weight and
includes the weight of all
occupants, cargo and all
nonfactory‐installed options.

locks the ignition and shift lever on
automatic transmission vehicles,
and the ignition and steering wheel
on manual transmission vehicles.
Do not turn the engine off when the
vehicle is moving. This will cause a
loss of power assist in the brake
and steering systems and disable
the airbags. If the vehicle must be shut off in an
emergency:
1. Brake using a firm and steady
pressure. Do not pump the
brakes repeatedly. This may
deplete power assist, requiring
increased brake pedal force.
2. Shift the vehicle to neutral. This can be done while the vehicle is
moving. After shifting to neutral,
firmly apply the brakes and steer
the vehicle to a safe location.
3. Come to a complete stop. Shift to P (Park) with an automatic
transmission, or Neutral with a
manual transmission. Turn the
ignition to LOCK/OFF.

accelerator pedal may damage
the transmission. If you are stuck,
do not spin the tires. When
stopping on a hill, use the brakes
to hold the vehicle in place.
Manual Mode
Driver Shift Control (DSC) or
Tap Shift
Notice: Driving with the engine at
a high rpm without upshifting
while using Driver Shift Control
(DSC), could damage the vehicle.
Always upshift when necessary
while using DSC. Vehicles with DSC may either use
the shift lever or the tap shift
controls on back of the steering
wheel to manually shift the
automatic transmission.
To use the DSC feature using the
shift lever:
1. Move the shift lever to
the right from D (Drive) to
M (Manual Mode).
The vehicle will be in sport mode
and will shift automatically if the
shift lever is not moved forward
or rearward. The transmission
may remain in a gear longer
than it would in the normal
driving mode based on braking,
throttle input, and vehicle lateral
acceleration. SPORT MODE will
be displayed in the DIC
momentarily.
2. To go from sport mode to DSC, move the shift lever forward to
upshift or rearward to downshift. 3. To exit DSC and enter sport
mode, hold the shift lever in the
upshift/forward position briefly.
If equipped, the tap shift controls
are on the back of the steering
wheel. The tap shift controls can be
used in D (Drive), M (Manual Mode)
with Sport Mode automatic shift
active, or M (Manual Mode) with
Manual Shifting Mode.

9-34 Driving and Operating
If driving safely on a wet road and it
becomes necessary to slam on the
brakes and continue braking to
avoid a sudden obstacle, 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
the driver steer around the obstacle
while braking hard.
As the brakes are applied, the
computer keeps receiving updates
on wheel speed and controls
braking pressure accordingly.Remember: ABS does not change
the time needed to get a foot up to
the brake pedal or always decrease
stopping distance. If you get too
close to the vehicle in front of you,
there will not be enough time to
apply the brakes if that vehicle
suddenly slows or stops. Always
leave enough room up ahead to
stop, even with ABS.
Using ABS
Do not pump the brakes. Just hold
the brake pedal down firmly and let
ABS work. You might hear the ABS
pump or motor operating and feel
the brake pedal pulsate, but this is
normal.
Braking in Emergencies
ABS allows the driver to steer and
brake at the same time. In many
emergencies, steering can help
more than even the very best
braking.
Parking Brake (Manual)
The parking brake pedal is located
on the lower portion of the
instrument panel to the left of the
steering wheel.
To set the parking brake, hold the
brake pedal down, then push the
parking brake pedal down.
If the ignition is on, the brake
system warning light on the
instrument panel cluster should
come on. If it does not, you need to

Black plate (35,1)Cadillac CTS/CTS-V Owner Manual (Include Mex) - 2012
Driving and Operating 9-35
have the vehicle serviced. See
Brake System Warning Light on
page 5‑22for more information.
To release the parking brake, pull
the release lever located to the left
of the steering wheel on the
instrument panel.
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
brake warning light is off before
driving. A warning chime will sound if the
parking brake is set, the ignition is
on, and the vehicle begins to move.
To stop the chime, fully release the
parking brake.
If you are towing a trailer and
parking on a hill, see
Driving
Characteristics and Towing Tips on
page 9‑56 for more information.
Parking Brake (Electric)
{WARNING
On vehicles with a manual
transmission, releasing the clutch
and pressing the accelerator will
release the Electric Parking
Brake. If the vehicle is not in a
gear, the vehicle could move, and
you or others could be injured.
Make sure the vehicle is in a gear
before attempting to drive away.
To avoid unexpected vehicle
movement, do not partially
release the clutch or press the

WARNING (Continued)
accelerator pedal until you are
ready to release the parking
brake and drive away.
Vehicles with the electric parking
brake (EPB) have a switch in the
center console.
The EPB takes the place of the
manual parking brake system, the
foot pedal and release handle. The
EPB can always be activated, even
if the ignition is OFF. To avoid

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
button again to turn the system back
on. For information on turning
StabiliTrak off and on, see
StabiliTrak System following.

SeeAccessories and Modifications
on page 10‑3 for more information.
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
assist with directional control of the
vehicle.

comes on and a DIC message
displays. Press the TCS/StabiliTrak
button again to turn both systems
back on.
If cruise control is being used when
the StabiliTrak activates, the cruise
control will automatically disengage.
When road conditions allow,
reengage the cruise control. See
Cruise Control on page 9‑41for
more information.
Competitive Driving Mode
To select this optional handling
mode, press the TCS/
StabiliTrak button quickly two times
and STABILITRAK COMPETITIVE MODE displays in the Driver
Information Center (DIC). While in
the StabiliTrak Competitive Mode,
the StabiliTrak Off light comes on,
TCS does not limit wheel spin, and
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.
