XM™Satellite Radio Service
XM Satellite Radio Service gives digital radio reception
from coast-to-coast in the 48 contiguous United States,
and in Canada. Just as with FM, tall buildings or hills
can interfere with satellite radio signals, causing the
sound to fade in and out. In addition, traveling or
standing under heavy foliage, bridges, garages,
or tunnels may cause loss of the XM signal for a
period of time.
Cellular Phone Usage
Cellular phone usage may cause interference with
the vehicle's radio. This interference may occur
when making or receiving phone calls, charging the
phone's battery, or simply having the phone on. This
interference causes an increased level of static while
listening to the radio. If static is received while listening
to the radio, unplug the cellular phone and turn it off.
Backglass Antenna
The AM-FM antenna is integrated with the rear window
defogger, located in the rear window. Make sure that the
inside surface of the rear window is not scratched and
that the lines on the glass are not damaged. If the
inside surface is damaged, it could interfere with radio
reception. For proper radio reception, the antenna
connector needs to be properly attached to the post on
the glass. If a cellular telephone antenna needs to be attached to
the glass, make sure that the grid lines for the AM-FM
antenna are not damaged. There is enough space
between the grid lines to attach a cellular telephone
antenna without interfering with radio reception.
Notice:
Using a razor blade or sharp object to clear
the inside rear window can damage the rear window
antenna and/or the rear window defogger. Repairs
would not be covered by the vehicle warranty. Do
not clear the inside rear window with sharp objects.
Notice: Do not apply aftermarket glass tinting
with metallic film. The metallic film in some tinting
materials will interfere with or distort the incoming
radio reception. Any damage caused to your
backglass antenna due to metallic tinting materials
will not be covered by the vehicle warranty.
XM™ Satellite Radio Antenna
System
The XM Satellite Radio antenna is located on the roof
or the rear of the vehicle. Keep the antenna clear of
obstructions for clear radio reception.

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.

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
System (TCS)
on page 5‑9. The following information
describes the operation of the TC button for changing
Traction Control and Stability Control 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, 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.

Before Leaving on a Long Trip
To prepare your vehicle for a long trip, consider having
it serviced by your dealer before departing.
Things to check on your own include:
.Windshield Washer Fluid:Reservoir full? Windows
clean —inside and outside?
.Wiper Blades: In good shape?
.Fuel, Engine Oil, Other Fluids: All levels checked?
.Lamps:Do they all work and are lenses clean?
.Tires:Are treads good? Are tires inflated to
recommended pressure?
.Weather and Maps: Safe to travel? Have
up-to-date maps?
Highway Hypnosis
Always be alert and pay attention to your surroundings
while driving. If you become tired or sleepy, find a safe
place to park your vehicle and rest.
Other driving tips include:
.Keep the vehicle well ventilated.
.Keep interior temperature cool.
.Keep your eyes moving —scan the road ahead
and to the sides.
.Check the rearview mirror and vehicle instruments
often.

Hill and Mountain Roads
Driving on steep hills or through mountains is different
than driving on flat or rolling terrain. Tips for driving in
these conditions include:
.Keep the vehicle serviced and in good shape.
.Check all fluid levels and brakes, tires, cooling
system, and transmission.
.Going down steep or long hills, shift to a
lower gear.
{WARNING:
If you do not shift down, the brakes could get so
hot that they would not work well. You would then
have poor braking or even none going down a hill.
You could crash. Shift down to let the engine
assist the brakes on a steep downhill slope.
{WARNING:
Coasting downhill in N (Neutral) or with the
ignition off is dangerous. The brakes will have to
do all the work of slowing down and they could
get so hot that they would not work well. You
would then have poor braking or even none going
down a hill. You could crash. Always have the
engine running and the vehicle in gear when
going downhill.
.Stay in your own lane. Do not swing wide or cut
across the center of the road. Drive at speeds that
let you stay in your own lane.
.Top of hills: Be alert—something could be in your
lane (stalled car, accident).
.Pay attention to special road signs (falling rocks
area, winding roads, long grades, passing or
no-passing zones) and take appropriate action.

Blizzard Conditions
Being stuck in snow can be in a serious situation. Stay
with the vehicle unless there is help nearby. If possible,
use theRoadside Service
on page 8‑8. To get help
and keep everyone in the vehicle safe:
.Turn on the Hazard Warning Flasherson
page 4‑3.
.Tie a red cloth to an outside mirror.
{WARNING:
Snow can trap engine exhaust under the vehicle.
This may cause exhaust gases to get inside.
Engine exhaust contains carbon monoxide (CO)
which cannot be seen or smelled. It can cause
unconsciousness and even death.
If the vehicle is stuck in the snow:
.Clear away snow from around the base of
your vehicle, especially any that is blocking
the exhaust pipe.
.Check again from time to time to be sure
snow does not collect there.
(Continued)
WARNING: (Continued)
.Open a window about 5 cm (two inches) on
the side of the vehicle that is away from the
wind to bring in fresh air.
.Fully open the air outlets on or under the
instrument panel.
.Adjust the Climate Control system to a setting
that circulates the air inside the vehicle and
set the fan speed to the highest setting. See
Climate Control System in the Index.
For more information about carbon monoxide, see
Engine Exhaust on page 3‑36.
Snow can trap exhaust gases under your vehicle.
This can cause deadly CO (carbon monoxide) gas
to get inside. CO could overcome you and kill you.
You cannot see it or smell it, so you might not
know it is in your vehicle. Clear away snow from
around the base of your vehicle, especially any
that is blocking the exhaust.
