2009 CADILLAC CTS warning lights

StabiliTrak®System
The vehicle has an electronic stability control system
called StabiliTrak. It is an advanced computer controlled
system that assists with directional control of the vehicle
in difficult driving conditions.
StabiliTrak activates when the computer senses a
discrepancy between your 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, the Traction Control System
(TCS)/StabiliTrak warning light on the instrument panel
cluster ashes. 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.
If there is a problem detected with StabiliTrak, a Service
Stability System message displays on the Driver
Information Center (DIC) and the TCS/StabiliTrak
warning light on the instrument panel cluster comes on.
When this message and warning light displays, the
system is not operational. Driving should be adjusted
accordingly. SeeDIC Warnings and Messages on
page 3-58andWarning Lights, Gages, and Indicators
on page 3-30for more information.StabiliTrak comes on automatically whenever the vehicle
is started. The system should be left on to help assist with
directional control of the vehicle. If StabiliTrak needs to
be turned off, press the TC (traction control) on/off button.
SeeTraction Control System (TCS) on page 4-6.
If cruise control is being used when the StabiliTrak
activates, the cruise control will automatically disengage.
When road conditions allow, reengage the cruise control.
SeeCruise Control on page 3-14for more information.
Traction Control System (TCS)
The vehicle has a Traction Control System (TCS) that
limits wheel spin. This is especially useful in slippery
road conditions. On a rear-wheel-drive vehicle, the
system operates if it senses that one or both of the rear
wheels are spinning or beginning to lose traction. On an
All-Wheel-Drive (AWD) vehicle, the system will operate if
it senses that any of the wheels are spinning or beginning
to lose traction. When this happens, the system brakes
the spinning wheel(s) and/or reduces engine power to
limit wheel spin.
The system may be heard or felt while it is working, but
this is normal.
The TCS/StabiliTrak
®warning light will ash when the
traction control system is limiting wheel spin.

Turn Signals When Towing a Trailer
The arrows on the instrument panel ash whenever
signaling a turn or lane change. Properly hooked up, the
trailer lamps also ash, telling other drivers the vehicle
is turning, changing lanes or stopping.
When towing a trailer, the arrows on the instrument
panel ash for turns even if the bulbs on the trailer are
burned out. For this reason you may think other
drivers are seeing the signal when they are not. It is
important to check occasionally to be sure the
trailer bulbs are still working.
The vehicle has bulb warning lights. When a trailer
lighting system is plugged into the vehicle’s lighting
system, its bulb warning lights may not let the driver
know if one of the lamps goes out. So, when the a trailer
lighting system plugged in, be sure to check the
vehicle and trailer lamps from time to time to be sure
they are all working. Once the trailer lamps are
disconnected, the bulb warning lights can again let the
driver know that one of the vehicle lamps is out.
Driving On Grades
Reduce speed and shift to a lower gearbeforestarting
down a long or steep downgrade. If the transmission is
not shifted down, the brakes might have to be used so
much that they would get hot and no longer work well.
On a long uphill grade, shift down and reduce the
vehicle’s speed to around 45 mph (70 km/h) to reduce
the possibility of the engine and the transmission
overheating.
Vehicles can tow in D (Drive). Shift the transmission to
a lower gear if the transmission shifts too often under
heavy loads and/or hilly conditions. For vehicles with a
manual transmission, it is better not to use the
highest gear.
When towing at high altitude on steep uphill grades,
consider the following: Engine coolant will boil at a lower
temperature than at normal altitudes. If the engine is
turned off immediately after towing at high altitude
on steep uphill grades, the vehicle may show signs
similar to engine overheating. To avoid this, let
the engine run while parked, preferably on level ground,
with the automatic transmission in P (Park) or the
manual transmission in N (Neutral) for a few minutes
before turning the engine off. If the overheat warning
comes on, seeEngine Overheating on page 5-37.
