For vehicles with the Active Steering with Enhanced
StabiliTrak option, in some cases when the SERVICE
STABILITY SYS message is displayed, a larger degree
of steering wheel input at low vehicle speeds and a
smaller degree of steering wheel input at higher vehicle
speeds may be required.
SERVICE STEERING SYS (System)
Your vehicle has a speed variable assist steering
system. Your All-Wheel Drive (AWD) vehicle may have
the Active Steering with Enhanced StabiliTrak option.
See“Active Steering” underSteering on page 5‑11.
This message displays if a problem is detected with the
speed variable assist steering system or the Active
Steering system. When this message is displayed, you
may notice that the effort required to steer the vehicle
increases or feels heavier, but you will still be able to
steer the vehicle. See Steering
on page 5‑11for more
information. Have the steering system inspected by
your dealer as soon as possible. If the SERVICE STEERING SYS message appears
because the Active Steering system needs service,
normal power steering is still operational. However,
compared to Active Steering, normal power steering
requires a larger degree of steering wheel input at low
vehicle speeds and a smaller degree of steering wheel
input at high vehicle speeds. The center position of the
steering wheel may be different. You may continue to
drive your vehicle with normal power steering, but have
the steering system inspected by your dealer as soon
as possible.
If the Active Steering system needs service, the system
may be operating in the Stability Secure Mode and the
STABILITY SECURE MODE message will display. See
Enhanced StabiliTrak
®on page 5‑7.
When certain steering faults are present, the vehicle
speed may be limited. If vehicle speed is limited, the
SPEED LIMITED TO XXX message will display. See
“Active Steering” underSteering on page 5‑11.

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.

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.
5-11

Black plate (12,1)Cadillac STS Owner Manual - 2011
SeeDIC Warnings and Messageson page 4‑76. The
normal power steering system is still operational. You
might notice that the center position of the steering
wheel is changed and that more steering effort at low
speeds and less steering effort at high speeds is
required. You can continue to drive the vehicle with
normal power steering but you should have your dealer
inspect the steering system as soon as possible in
order to have the problem corrected and the steering
wheel position centered.
When stability control activates, the system
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. Adjustments to the steering will not be felt in
the steering wheel. See Enhanced StabiliTrak
®on
page 5‑7.
It is recommended that the battery not be disconnected
when the steering wheel is turned from the center
position. If this occurs, the center position of the
steering wheel could be temporarily changed a small
amount. You can continue to operate the vehicle and,
after a short time, the center position of the steering
wheel will return to normal.
Steering Tips
It is important to take curves at a reasonable speed.
Traction in a curve depends on the condition of the tires
and the road surface, the angle at which the curve is
banked, and vehicle speed. While in a curve, speed is
the one factor that can be controlled.
If there is a need to reduce speed, do it before entering
the curve, while the front wheels are straight.
Try to adjust the speed so you can drive through the
curve. Maintain a reasonable, steady speed. Wait to
accelerate until out of the curve, and then accelerate
gently into the straightaway.
To help you steer in the direction you want to go, during
certain sharp or sudden cornering maneuvers, gear
selection is controlled. This will maximize the available
drive wheel torque and minimize the transmission
response time and shift activity. During this kind of
maneuver, the transmission shifts automatically as
vehicle speed changes.
