service CADILLAC STS 2008 1.G Service Manual

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 4-13.
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. SeeSteering
on page 4-13for more information. Have the steering
system inspected by your dealer/retailer 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/retailer 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.
SeeEnhanced StabiliTrak
®on page 4-9.
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 4-13.
SERVICE SUSPENSION SYS (System)
This message displays when the suspension system
is not operating properly. Have your vehicle serviced
by your dealer/retailer.
If your All-Wheel Drive (AWD) vehicle has the Active
Steering with Enhanced StabiliTrak
®option and
the suspension system needs service, the Enhanced
StabiliTrak
®system may be operating in the Stability
Secure Mode and the STABILITY SECURE MODE
message will display. SeeEnhanced StabiliTrak
®
on page 4-9.

page 2-48in this manual for more information.
Radio Reception
Frequency interference and static can occur during
normal radio reception if items such as cell phone
chargers, vehicle convenience accessories, and external
electronic devices are plugged into the accessory
power outlet. If there is interference or static, unplug
the item from the accessory power outlet.
AM
The range for most AM stations is greater than for FM,
especially at night. The longer range can cause station
frequencies to interfere with each other. For better radio
reception, most AM radio stations boost the power levels
during the day, and then reduce these levels during the
night. Static can also occur when things like storms and
power lines interfere with radio reception. When this
happens, try reducing the treble on your radio.
FM Stereo
FM stereo gives the best sound, but FM signals only
reach about 10 to 40 miles (16 to 65 km). Tall buildings
or hills can interfere with FM signals, causing the
sound to fade in and out.
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 through tunnels could cause loss
of the XM™ signal for a period of time. The radio
may display NO XM SIGNAL to indicate interference.
3-123

Magnetic Ride Control
Your vehicle may have Magnetic Ride Control that
automatically adjusts the ride of your vehicle. Automatic
ride control is achieved through a computer used to
control and monitor the suspension system. The
controller receives input from various sensors to
determine the proper system response. If the controller
detects a problem within the system, the DIC will
display a SERVICE SUSPENSION SYS message. See
DIC Warnings and Messages on page 3-80for more
information. See your dealer for service.
Limited-Slip Rear Axle
Your limited-slip rear axle can give you additional
traction on snow, mud, ice, sand or gravel. It works like
a standard axle most of the time, but when one of
the rear wheels has no traction and the other does, this
feature will allow the wheel with traction to move the
vehicle.
StabiliTrak®System
Your 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 your all-wheel-drive vehicle has the optional enhanced
vehicle stability control system called Active Steering
with Enhanced StabiliTrak
®, seeEnhanced StabiliTrak®
on page 4-9.
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 direction which
you are steering.
When the system activates, a STABILITY SYS ACTIVE
message will be displayed on the Driver Information
Center (DIC). SeeDIC Warnings and Messages
on page 3-80. You may also hear a noise or feel
vibration in the brake pedal. This is normal. Continue to
steer the vehicle in the direction you want it to go.
4-8

If there is a problem detected with StabiliTrak®,a
SERVICE STABILITY SYS message will be displayed
on the DIC. SeeDIC Warnings and Messages on
page 3-80. When this message is displayed, the system
is not operational. Driving should be adjusted
accordingly.
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 TC (traction
control) on/off button. SeeTraction Control System
(TCS) on page 4-6.
If the vehicle is in cruise control when the StabiliTrak
®
activates, the cruise control will automatically disengage.
When road conditions allow you to safely use it again,
you may reengage the cruise control. SeeCruise Control
on page 3-17orAdaptive Cruise Control on page 3-20for
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 off set 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,
modies 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).
SeeDIC Warnings and Messages on page 3-80You may
also hear a noise or feel vibration in the brake pedal. This
is normal. Continue to steer the vehicle in the direction
you want it to go.
