brake light CADILLAC STS 2009 1.G Owners Manual

If the engine does not start and the security light comes
on, there may be a problem with the immobilizer
system. Press the START button again.
If the vehicle does not start and the keyless access
transmitter appears to be undamaged, try another
keyless access transmitter. Or, place the transmitter in
the transmitter pocket. See “NO FOBS DETECTED”
underDIC Warnings and Messages on page 3-79for
additional information. Check the fuse. SeeFuses and
Circuit Breakers on page 5-123. If the engine still does
not start with the other transmitter, the vehicle needs
service. If the engine does start, the rst transmitter may
be faulty. See your dealer/retailer or have a new keyless
access transmitter programmed to the vehicle.
The immobilizer system can learn new or replacement
keyless access transmitters. Up to four keyless access
transmitters can be programmed for the vehicle.
To program additional transmitters, see “Matching
transmitter(s) to Your Vehicle” underKeyless Access
System Operation on page 2-5.
Do not leave the key or device that disarms or
deactivates the theft deterrent system in the vehicle.Starting and Operating Your
Vehicle
New Vehicle Break-In
Notice:The vehicle does not need an elaborate
break-in. But it will perform better in the long run if
you follow these guidelines:
Do not drive at any one constant speed, fast or
slow, for the rst 500 miles (805 km). Do not
make full-throttle starts. Avoid downshifting
to brake or slow the vehicle.
Avoid making hard stops for the rst 200 miles
(322 km) or so. During this time the new brake
linings are not yet broken in. Hard stops with
new linings can mean premature wear and earlier
replacement. Follow this breaking-in guideline
every time you get new brake linings.
Do not tow a trailer during break-in. SeeTowing a
Trailer (Vehicles Without Heavy Duty Cooling) on
page 4-31orTowing a Trailer (Vehicles With
Heavy Duty Cooling) on page 4-32for the trailer
towing capabilities of your vehicle and more
information.
Following break-in, engine speed and load can be
gradually increased.
2-25

If shifting is prevented for any reason, the selected gear
will ash multiple times, indicating that the transmission
has not shifted gears.
The transmission will allow you to shift to the gear
selected and will automatically downshift when the
vehicle comes to a stop. This will allow for more
power during take-off and passing.
Parking Brake
The parking brake pedal is
located on the lower portion
of the instrument panel to
the left of the steering
wheel.
The vehicle has a push-to-release parking brake pedal.
To set the parking brake, hold the brake pedal down,
then push the parking brake pedal down.If the ignition is on, the brake system warning light on
the instrument panel cluster should come on. If it does
not, you need to have the vehicle serviced. SeeBrake
System Warning Light on page 3-62for more information.
To release the parking brake, hold the brake pedal
down, then push the parking brake pedal. When you
release the park brake pedal, the parking brake
releases.
Notice:Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Make sure
that the parking brake is fully released and the brake
warning light is off before driving.
A warning chime will sound if the parking brake is set,
the ignition is on and the vehicle begins to move.
To stop the chime, fully release the parking brake.
If you are towing a trailer and parking on a hill,
seeTowing a Trailer (Vehicles Without Heavy Duty
Cooling) on page 4-31orTowing a Trailer (Vehicles
With Heavy Duty Cooling) on page 4-32for more
information.

When the System Does Not Seem to
Work Properly
If the URPA system will not activate due to a temporary
condition a red light will be shown on the rear URPA
display when the shift lever is moved into R (Reverse).
This occurs under the following conditions:
The ultrasonic sensors are not clean. Keep your
rear bumper free of mud, dirt, snow, ice and slush.
For cleaning instructions, seeWashing Your Vehicle
on page 5-118.
The ultrasonic sensors are not clean. Keep the
vehicle’s rear bumper free of mud, dirt, snow,
ice and slush. For cleaning instructions, see
Washing Your Vehicle on page 5-118.
A trailer was attached to the vehicle, or a bicycle or
an object was hanging out of the trunk during the
last drive cycle, the red light may illuminate in the
rear display. Once the attached object is removed,
URPA will return to normal operation.
The vehicle’s bumper is damaged. Take the vehicle
to your dealer/retailer to repair the system.
Other conditions may affect system performance,

Reducing Speed While Using Cruise
Control
There are two ways to reduce your speed while using
cruise control:
PressTat the end of the lever until the lower
speed desired is reached, then release it.
To slow down in very small amounts, briey
press
T. Each time this is done, the vehicle
goes about 1 mph (1.6 km/h) slower.
Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase your vehicle
speed. When you take your foot off the pedal, the
vehicle slows down to the cruise control speed you
set earlier.
Using Cruise Control on Hills
How well the cruise control works on hills depends upon
the vehicle speed, load, and the steepness of the hills.
When going up steep hills, you might have to step on the
accelerator pedal to maintain the vehicle’s speed. When
going downhill, you might have to brake to keep the
vehicle’s speed down. Applying the brake will turn off the
cruise control. If you need to apply the brake due to the
grade of the downhill slope, you might not want to attempt
to use the cruise control feature.
Ending Cruise Control
There are three ways to end cruise control.
Step lightly on the brake pedal. This will end the
current cruise control session.
Move the cruise control switch to9to turn off the
system completely.
Press the[button on the steering wheel.
Erasing Speed Memory
The cruise control set speed memory is erased when
the cruise control or the ignition is turned off.
3-19

{CAUTION:
When the Adaptive Cruise Control radar is blocked
by snow, ice, or dirt, it may not detect a vehicle
ahead. Adaptive Cruise Control may not have time
to slow your vehicle enough to avoid a collision.
Do not use Adaptive Cruise Control when the
radar is blocked by snow, ice, or dirt. Keep your
radar clean. See “Cleaning the System” later in
this section.
Adaptive Cruise Control automatically slows your vehicle
down when approaching a slower moving vehicle. It then
adjusts your speed to follow the vehicle in front at the
selected following distance. Your speed increases or
decreases to follow the vehicle in front of you but will
not exceed the set speed. It may apply limited braking,
if necessary. When braking is active, your brake lights
come on. It may feel or sound different than if you were
applying the brakes yourself. This is normal.
Stationary or Very Slow-Moving Objects
{CAUTION:
Adaptive Cruise Control may not detect and
react to stationary or slow-moving vehicles or
other objects ahead of you. You could crash into
an object ahead of you. Do not use Adaptive
Cruise Control when approaching stationary
or slow-moving vehicles or other objects.
{CAUTION:
Adaptive Cruise Control may not detect and react
to stationary or slow-moving vehicles or other
objects ahead of you. Your vehicle may accelerate
toward objects, such as a stopped vehicle that
suddenly appears after the lead vehicle changes
lanes. Your complete attention is always required
while driving and you should be ready to take
action and apply the brakes.
3-27

With Twilight Sentinel the following will happen:
When it is dark enough outside, the front turn signal
lamps (DRL) will go off, and the headlamps and
parking lamps will come on. The other lamps
that come on with headlamps will also come on.
When it is bright enough outside, the headlamps
will go off, and the front turn signal lamps (DRL)
will come on, as long as the exterior lamp switch
is in the off position.
If the vehicle is started in a dark garage, the automatic
headlamp system comes on immediately. Once the
vehicle leaves the garage, it will take about one minute
for the automatic headlamp system to change to DRL
if it is light outside. During that delay, the instrument
panel cluster might not be as bright as usual. Make sure
the instrument panel brightness control is in full bright
position. SeeInstrument Panel Brightness on page 3-40
for more information.
You can idle the vehicle with the lamps off, even when
it is dark outside. First set the parking brake while the
ignition is in OFF/ACCESSORY. Then start the vehicle.
The lamps will stay off until the parking brake is released.Twilight Sentinel also provides exterior illumination as
you leave the vehicle. If Twilight Sentinel has turned on
the lamps when you turn off the ignition, the lamps
will remain on until:
The exterior lamp switch is moved from off to the
parking lamp position.
A delay time that you select has elapsed.
SeeVehicle Personalization on page 2-61to select the
delay time needed. You can also select no delay time.
If the ignition is turned off with the exterior lamp switch
in the parking lamp or headlamp position, the Twilight
Sentinel delay will not occur. The lamps will turn off
as soon as the switch is turned off.
As with any vehicle, the regular headlamp system
should be turned on when needed.
3-39

Brake System Warning Light
The vehicle’s hydraulic brake system is divided into
two parts. If one part is not working, the other part
can still work and stop the vehicle. For good braking
both parts need to be working.
If the warning light comes on, there is a brake problem.
Have the brake system inspected right away.
This light comes on briey when the engine is turned
on. If it does not come on then, have it xed so it will
be ready to warn if there is a problem.When the ignition is on, the brake system warning light
also comes on when the parking brake is set. The light
will stay on if the parking brake does not release fully. If it
stays on after the parking brake is fully released, it means
there is a brake problem.
If the light comes on while driving, pull off the road and
stop carefully. The pedal may be harder to push, or
the pedal may go closer to the oor. It may take longer
to stop. If the light is still on, have the vehicle towed
for service. SeeTowing Your Vehicle on page 4-29.
{CAUTION:
The brake system might not be working properly if
the brake system warning light is on. Driving with
the brake system warning light on can lead to a
crash. If the light is still on after the vehicle has
been pulled off the road and carefully stopped,
have the vehicle towed for service. United States
Canada

Antilock Brake System (ABS)
Warning Light
For vehicles with
the Antilock Brake
System (ABS), this light
comes on briey when
the engine is started.
If it does not, have the vehicle serviced by your
dealer/retailer. If the system is working normally the
indicator light then goes off.
If the ABS light stays on, turn the ignition off. If the
light comes on while driving, stop as soon as it is safely
possible and turn the ignition off. Then start the engine
again to reset the system. If the ABS light stays on, or
comes on again while driving, the vehicle needs service.
If the regular brake system warning light is not on, the
vehicle still has brakes, but not antilock brakes. If the
regular brake system warning light is also on, the vehicle
does not have antilock brakes and there is a problem with
the regular brakes. SeeBrake System Warning Light on
page 3-62.
For vehicles with a Driver Information Center (DIC),
seeDIC Warnings and Messages on page 3-79for
all brake related DIC messages.
Traction Control System (TCS)
Warning Light
The TCS warning light
comes on briey when
the engine is started.
If it does not, have the vehicle serviced by your
dealer/retailer.
If the Traction Control System (TCS) warning light
comes on and stays on, there may be a problem with
the TCS.
The light also comes on if the TCS is turned off using
the traction control on/off button located on the console.
If this light stays on or comes on while driving, pull
off the road as soon as possible and stop carefully.
Turn the engine off and then restart it. If the light still
stays on or comes back on again while driving, the
vehicle needs service. Have the TCS inspected as
soon as possible. SeeTraction Control System (TCS)
