Pairing
A Bluetooth cell phone must be paired to the Bluetooth
system and then connected to the vehicle before it can
be used. See your cell phone manufacturer's user guide
for Bluetooth functions before pairing the cell phone. If a Bluetooth phone is not connected, calls will be made
using OnStar
®Hands‐Free Calling, if available. Refer
to the OnStar Owner's Guide for more information.
Pairing Information
.Up to five cell phones can be paired to the
Bluetooth system.
.The pairing process is disabled when the vehicle is
moving.
.Pairing only needs to be completed once, unless
the pairing information on the cell phone changes
or the cell phone is deleted from the system.
.Only one paired cell phone can be connected to
the Bluetooth system at a time.
.If multiple paired cell phones are within range
of the system, the system connects to the first
available paired cell phone in the order that they
were first paired to the system. To connect to a
different paired phone, see “Connecting to a
Different Phone” later in this section.
Pairing a Phone
1. Press and holdbgfor two seconds.
2. Say “Bluetooth.”
3. Say “Pair.”The system responds with instructions
and a four‐digit Personal Identification Number
(PIN). The PIN is used in Step 5.
4. Start the pairing process on the cell phone that you want to pair. For help with this process, see your
cell phone manufacturer's user guide.
5. Locate the device named “Your Vehicle”in the list
on the cell phone. Follow the instructions on the
cell phone to enter the PIN number that was
provided in Step 3. After the PIN is successfully
entered, the system prompts you to provide a
name for the paired cell phone. This name will be
used to indicate which phones are paired and
connected to the vehicle. See “Listing All Paired
and Connected Phones” later in this section for
more information.
6. Repeat Steps 1 through 5 to pair additional phones.

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.
