Antilock Brake System (ABS)
This vehicle has the Antilock Brake System (ABS), an
advanced electronic braking system that helps prevent
a braking skid.
When the engine is started and the vehicle begins to
drive away, ABS checks itself. A momentary motor or
clicking noise might be heard while this test is going on,
and it might even be noticed that the brake pedal
moves a little. This is normal.
If there is a problem with
ABS, this warning light
stays on. SeeAntilock
Brake System (ABS)
Warning Light
on
page 4‑59.
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 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 antilock work. The antilock pump or
motor might be heard operating and the brake pedal
might be felt to 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.
Brake Assist
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.
StabiliTrak®System
The vehicle has a vehicle stability enhancement system
called StabiliTrak. It is an advanced computer controlled
system that assists with directional control of the vehicle
in difficult driving conditions.
If the vehicle has all‐wheel‐drive and has Active
Steering with Enhanced StabiliTrak, seeEnhanced
StabiliTrak
®on page 5‑7.
StabiliTrak activates when the computer 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 intended
direction.
When the system activates, a STABILITY SYS ACTIVE
message will be displayed on the Driver Information
Center (DIC). See DIC Warnings and Messages
on
page 4‑76. A noise may be heard or a vibration 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, a
SERVICE STABILITY SYS message will be displayed
on the DIC. See DIC Warnings and Messages
on
page 4‑76. When this message is displayed, the
system is not operational. Driving should be adjusted
accordingly.
5-6

Black plate (7,1)Cadillac STS Owner Manual - 2011
StabiliTrak comes on automatically whenever the
vehicle is started. To help assist with directional control
of the vehicle, always leave the system on. StabiliTrak
can be turned off, however, by using the Traction
Control System (TCS)/StabiliTrak button. SeeTraction
Control System (TCS) on page 5‑9.
If cruise control is being used when StabiliTrak
activates, it will automatically disengage. Cruise control
may be reengaged when road conditions allow. See
Cruise Control
on page 4‑12or Adaptive Cruise
Controlon page 4‑15for more information.
Enhanced StabiliTrak®
All‐wheel‐drive (AWD) vehicles with the Active Steering
with Enhanced StabiliTrak option have an enhanced
computer controlled vehicle stability system that assists
with directional control of the vehicle in difficult driving
conditions. This system coordinates automatic control of
the Active Steering System, the Magnetic Ride Control
Suspension System, and the Brake Control System for
better vehicle performance.
During extreme cold temperature conditions, the active
steering function may be temporarily disabled which
may cause the steering wheel to be offset from the
center position while driving straight. This is normal
operation and the vehicle is safe to drive in these
cases. Stability control activates when the computer senses a
difference between the intended path and the direction
the vehicle is actually traveling. Stability control
automatically adjusts the front road wheel steering
angle, modifies the suspension stiffness, and selectively
applies braking pressure at any one of the vehicle’s
brakes to help maintain directional control of the
vehicle.
When the system activates, a STABILITY SYS ACTIVE
message displays on the Driver Information Center
(DIC). See
DIC Warnings and Messages
on page 4‑76.
It is normal to hear a noise or feel vibration in the brake
pedal when the system is working. Continue to steer the
vehicle in the intended direction.
If cruise control is engaged when Enhanced
StabiliTrak activates, the cruise control will
automatically disengage. Re-engage cruise control
when road conditions allow. See Cruise Control
on
page 4‑12, or Adaptive Cruise Controlon page 4‑15for more information.
Enhanced StabiliTrak comes on automatically in the
Stability Touring Mode, when the vehicle is started.
The Stability Touring Mode is recommended for normal
driving.
5-7

Black plate (8,1)Cadillac STS Owner Manual - 2011
To assist with directional control of the vehicle, always
leave the system on. Stability control can be turned off
however, by using the TC button. SeeTraction Control
System (TCS)
on page 5‑9. The STABILITY SYS
OFF message will be displayed on the DIC. See DIC
Warnings and Messages on page 4‑76.
If there is a problem detected with Enhanced
StabiliTrak, the SERVICE STABILITY SYS message
will be displayed on the DIC. See DIC Warnings and
Messages
on page 4‑76. When this message is
displayed, the system is not operating. Driving should
be adjusted accordingly.
When certain faults or vehicle conditions are detected,
the Stability control will automatically go into a secure
mode and the STABILITY SECURE MODE message
will be displayed on the DIC. When the Stability Secure
Mode is activated, the stability control system will not
respond to driver requests to change the stability mode
until the next ignition cycle or until the vehicle condition
or fault is returned to normal. When the Stability Secure
Mode is activated, other messages may be displayed,
such as SERVICE STEERING SYS, SERVICE
SUSPENSION SYS or CHECK TIRE PRESSURE on
the DIC. When the Stability Secure Mode is activated,
a larger degree of steering wheel input at low vehicle
speeds and a smaller degree of steering wheel input at
high vehicle speeds may be required. Stability Secure Mode will be activated if a compact spare tire is being
used. See
DIC Warnings and Messages
on page 4‑76andCompact Spare Tire on page 6‑105.
Persistent operation of the vehicle in the STABILITY
SECURE MODE may be an indication that the vehicle
needs to be serviced by your dealer.
When certain faults are present, the vehicle’s speed
may be limited and the SPEED LIMITED TO XXX
message will be displayed on the DIC. See DIC
Warnings and Messages
on page 4‑76. When the
vehicle’s speed is limited, other messages may be
displayed, such as SERVICE STABILITY SYS,
SERVICE STEERING SYS or SERVICE SUSPENSION
SYS on the DIC. Have the vehicle serviced by your
dealer.
Enhanced StabiliTrak and Traction Control
Mode Selection
Enhanced StabiliTrak can be operated in Touring Mode.
It can also be turned off. The TC button is used to
change stability control modes (Touring or Off) as well
as to turn traction control on or off. See Traction Control

page 5‑9.
.To turn traction control on while in the Stability
Touring Mode, press and release the TC button
and the traction control system warning light will
turn off.
Traction Control System (TCS)
The vehicle has a traction control system 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.
This warning light comes
on if there is a problem
with TCS.
See Traction Control System (TCS) Warning Light
on
page 4‑60. When this warning light is on, the system
will not limit wheel spin. Adjust your driving accordingly.
5-9

Black plate (10,1)Cadillac STS Owner Manual - 2011
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
TCS can be turned off if needed.
Notice:Do not repeatedly brake or accelerate
heavily when TCS is off. The vehicle's driveline
could be damaged.
When TCS is turned off on a vehicle with AWD, the
system may still be working. This is normal and
necessary with the hardware on the vehicle.
It may be necessary to turn the system off if the vehicle
gets stuck in sand, mud or snow and rocking the vehicle
is required. See Rocking Your Vehicle to Get It Out
on
page 5‑23and If Your Vehicle is Stuck in Sand, Mud,
Ice, or Snowon page 5‑22for more information. See
Winter Drivingon page 5‑20for information on using
TCS when driving in snowy or icy conditions.
To turn the system off,
press the TCS/StabiliTrak
button located near the
shift lever.
For AWD vehicles with the Active Steering with
Enhanced StabiliTrak option, the TCS/StabiliTrak button
is used to turn traction control on and off and to turn
StabiliTrak on and off. See Enhanced StabiliTrak
®on
page 5‑7for instructions on selecting the proper
stability control mode.
Press and release the TCS/StabiliTrak button and TCS
will turn off and the Traction Control System Warning
Light will come on. Press the button again to turn the
system back on.
Adding non‐GM accessories can affect the vehicle's
performance. See Accessories and Modifications
on
page 6‑4for more information.

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, engine power is sent to all four wheels
at all times. It is fully automatic, and adjusts itself as
needed for road conditions.
Steering
Power Steering
If power steering assist is lost because the engine stops
or the system is not functioning, the vehicle can be
steered but it will take more effort.
Speed Variable Assist Steering
The vehicle has a steering system that continuously
adjusts the effort felt when steering at all vehicle
speeds. It provides ease when parking, yet a firm,
solid feel at highway speeds.
Active Steering
All‐wheel‐drive vehicles with the Active Steering with
Enhanced StabiliTrak®option have an electronically
controlled active steering system. The active steering
system uses the steering actuator to automatically
adjust the front road wheel turning angle based on
vehicle speed and how much the steering wheel is
turned. This system reduces steering effort at low
speeds, improves steering feel at moderate speeds,
and reduces steering sensitivity at higher speeds.
During some operating conditions, the active steering
might deactivate to protect the system from damage.
You might notice that the center position of the steering
wheel is changed. Unless there is a SERVICE
STEERING SYS message, the system will return to
normal operation as soon as the condition ceases,
usually within a very short period of time.
At low speeds, the active steering system requires
less movement of the steering wheel to change vehicle
direction than the normal power steering system. Adjust
your driving accordingly.
When certain steering faults are present, the active
steering deactivates and vehicle speed might be
limited. The SERVICE STEERING SYS and SPEED
LIMITED TO XXX messages will be displayed.
