2009 CADILLAC STS cruise control

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 3-79. 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.
Cruise Control may be re-engaged when road conditions
allow. SeeCruise Control on page 3-16,orAdaptive
Cruise Control on page 3-20for 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. Enhanced StabiliTrak also has Stability
Competitive Mode that is turned on by pressing the
Traction Control (TC) button twice quickly. This mode is
designed to be used by the performance consciousdriver who desires less stability control intervention.
SeeCompetitive Driving Mode on page 4-11. When the
Stability Control Competitive Mode has been activated,
traction control operates in competitive mode and
cannot be turned off. The STABILITY COMPETITIVE
MODE message will be displayed on the DIC.
SeeDIC Warnings and Messages on page 3-79.
When operating the vehicle in the Stability Competitive
Mode, the system provides less stability control
intervention. Driving should be adjusted accordingly.
When the Stability Competitive Mode has been selected,
the Active Steering and Magnetic Ride Control Touring
Mode is not available. These systems are automatically
changed to the Performance Mode, providing more
response to road conditions and quicker steering
response. For more information, see “Active Steering
and Magnetic Ride Control Mode” in the Index of
the vehicle’s Navigation Manual.
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 4-10. The STABILITY
SYS OFF message will be displayed on the DIC.
SeeDIC Warnings and Messages on page 3-79.

Driving in Rain and on Wet Roads
Rain and wet roads can reduce vehicle traction and
affect your ability to stop and accelerate. Always drive
slower in these types of driving conditions and avoid
driving through large puddles and deep-standing or
owing water.
{CAUTION:
Wet brakes can cause crashes. They might not
work as well in a quick stop and could cause
pulling to one side. You could lose control of
the vehicle.
After driving through a large puddle of water or a
car/vehicle wash, lightly apply the brake pedal until
the brakes work normally.
Flowing or rushing water creates strong forces.
Driving through owing water could cause your
vehicle to be carried away. If this happens, you
and other vehicle occupants could drown. Do not
ignore police warnings and be very cautious about
trying to drive through owing water.
Hydroplaning
Hydroplaning is dangerous. Water can build up under
your vehicle’s tires so they actually ride on the water.
This can happen if the road is wet enough and you are
going fast enough. When your vehicle is hydroplaning,
it has little or no contact with the road.
There is no hard and fast rule about hydroplaning.
The best advice is to slow down when the road is wet.
Other Rainy Weather Tips
Besides slowing down, other wet weather driving tips
include:
Allow extra following distance.
Pass with caution.
Keep windshield wiping equipment in good shape.
Keep the windshield washer uid reservoir lled.
Have good tires with proper tread depth. SeeTires
on page 5-54.
Turn off cruise control.

Winter Driving
Driving on Snow or Ice
Drive carefully when there is snow or ice between the
tires and the road, creating less traction or grip. Wet ice
can occur at about 32°F (0°C) when freezing rain
begins to fall, resulting in even less traction. Avoid
driving on wet ice or in freezing rain until roads can be
treated with salt or sand.
Drive with caution, whatever the condition. Accelerate
gently so traction is not lost. Accelerating too quickly
causes the wheels to spin and makes the surface under
the tires slick, so there is even less traction.
Try not to break the fragile traction. If you accelerate too
fast, the drive wheels will spin and polish the surface
under the tires even more.TheTraction Control System (TCS) on page 4-10
improves the ability to accelerate on slippery roads,
but slow down and adjust your driving to the road
conditions. When driving through deep snow, turn off
the traction control system to help maintain vehicle
motion at lower speeds.
TheAntilock Brake System (ABS) on page 4-4improves
vehicle stability during hard stops on a slippery roads,
but apply the brakes sooner than when on dry
pavement.
Allow greater following distance on any slippery road
and watch for slippery spots. Icy patches can occur on
otherwise clear roads in shaded areas. The surface
of a curve or an overpass can remain icy when the
surrounding roads are clear. Avoid sudden steering
maneuvers and braking while on ice.
Turn off cruise control, if equipped, on slippery surfaces.

The underhood fuse block is located in the front of
the engine compartment on the passenger side of
the vehicle. SeeEngine Compartment Overview on
page 5-12for more information on location and removal
procedure for the front compartment underhood sights
shields.
To access the fuses, push in the tabs located on each
side of the fuse block cover, then lift the cover off.
Notice:Spilling liquid on any electrical components
on the vehicle may damage it. Always keep the
covers on any electrical component.
