brake light CADILLAC STS 2008 1.G Owners Manual

The transmission will only allow you to shift into gears
appropriate for the vehicle speed and engine
Revolutions Per Minute (RPM). The transmission will
not automatically shift to the next higher gear if the
engine RPM is too high.
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.This vehicle has a push-to-release parking brake pedal.
To set the parking brake, hold the regular brake
pedal down with your right foot and push the parking
brake pedal down with your left foot.
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 your vehicle serviced.
SeeBrake System Warning Light on page 3-64for
more information.
To release the parking brake, hold the brake pedal
down with your right foot and push the parking brake
pedal with your left foot. When you lift your left foot,
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,

When the System Does Not Seem to
Work Properly
The ultrasonic sensors are not clean, a red URPA
display light may illuminate when the vehicle is in
REVERSE (R). Keep your rear bumper free of mud,
dirt, snow, ice and slush. For cleaning instructions,
seeWashing Your Vehicle on page 5-110.
A trailer was attached to your vehicle, or a bicycle
or an object was hanging out of your trunk during
your last drive cycle, the red light may illuminate.
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,
such as vibrations from a jackhammer or the
compression of air brakes on a very large truck.
If the system is still disabled, after driving forward at
least 15 mph (25 km/h), take your vehicle to your
dealer/retailer.
Side Blind Zone Alert
Your vehicle may have a Side Blind Zone Alert (SBZA)
system. The SBZA system is an aid that may help
you avoid lane change crashes with vehicles in your side
blind spots (zones). Read the entire section before
using the system. See “Side Blind Zone Alert” in
the Index of the navigation manual.
Lane Departure Warning
Your vehicle may have a Lane Departure Warning
(LDW) system. The LDW system does not steer the
vehicle and is only an aid to help you stay in your driving
lane. Read the entire section before using the system.
See “Lane Departure Warning” in the Index of the
navigation manual.

Setting Cruise Control
{CAUTION:
If you leave your cruise control on when you
are not using cruise, you might hit a button
and go into cruise when you do not want to.
You could be startled and even lose control.
Keep the cruise control switch off until you
want to use cruise control.
1. Move the cruise control switch to on.
2. Get up to the speed desired.
3. Press in the set button at the end of the lever
and release it.
4. Take your foot off the accelerator pedal.
This light on the instrument
panel cluster comes on
while cruise control is on.
Resuming a Set Speed
If the cruise control is at the set speed desired and then
the brake is applied, the cruise control is disengaged.
But it does not need to be reset.
Once the vehicle speed reaches about 25 mph (40 km/h)
or more, you can move the cruise control switch
briey from on to resume/accelerate.
The vehicle will go right back up to your chosen speed
and stay there.
If you hold the switch at resume/accelerate the vehicle
will keep going faster until you release the switch or apply
the brake. Do not hold the switch at resume/accelerate,
unless you want the vehicle to go faster.
Increasing Speed While Using
Cruise Control
There are two ways to go to a higher speed:
Use the accelerator pedal to get to the higher
speed. Press the set button at the end of the lever,
then release the button and the accelerator
pedal. You will now cruise at the higher speed.
Move the cruise switch from on to resume/
accelerate. Hold it there until the desired speed is
reached, and then release the switch. To increase
your speed in very small amounts, move the switch
briey to resume/accelerate. Each time this is done,
your vehicle goes about 1 mph (1.6 km/h) faster.
3-18

If using the accelerator pedal and the set button at
end of the lever to increase cruise set speed, your new
set speed must be at least 5 mph higher than current
speed for this method to work. If it is not 5 mph higher,
switch cruise switch off, then on, and then reset your
speed using the set button.
Reducing Speed While Using
Cruise Control
There are two ways to reduce your speed while using
cruise control:
Press in the button at the end of the lever until you
reach the lower speed desired, then release it.
To slow down in very small amounts, briey press
the set button. 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 your
cruise control feature.
Ending Cruise Control
To end a cruise control session, step lightly on the
brake pedal.
Stepping on the brake pedal will end the current cruise
control session only. Move the cruise control switch
to off to turn off the system completely.
Erasing Speed Memory
When the cruise control or the ignition is turned off,
the cruise control set speed memory is erased.
3-19

Approaching and Following a Vehicle
The vehicle ahead
symbol only appears
on the HUD when a
vehicle ahead is
detected in your path.
If this symbol does not appear, or disappears briey,
Adaptive Cruise Control will not respond to vehicles
you may see ahead.{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.
3-27

If you start your vehicle in a dark garage, the automatic
headlamp system will come on immediately. Once you
leave 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 3-41
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 2-60to select
the delay time that you want. 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.
Exterior Lighting Battery Saver
If the parking lamps or headlamps have been left on,
the exterior lamps will turn off about 10 minutes after
the ignition is turned off. This protects against draining
the battery in case you have accidentally left the
headlamps or parking lamps on. The battery saver
does not work if the headlamps are turned on after
the ignition is turned off.
If you need to leave the lamps on for more than
10 minutes, use the exterior lamp control to turn
the lamps back on.
3-40

As light shines out from the HUD, it is possible for light
to shine back in. In rare occurrences, when the sun
is at a specic angle and position, the sun’s rays can
shine back into the HUD. When this occurs, the display
device within the HUD will be temporarily illuminated.
The event will end when the vehicle’s angle to the
sun changes.
Clean the inside of the windshield as needed to remove
any dirt or lm that reduces the sharpness or clarity
of the HUD image.
To clean the HUD, spray household glass cleaner on a
soft, clean cloth. Wipe the HUD lens gently, then dry it.
Notice:When cleaning, be careful not to scratch the
HUD or camera lenses. Do not spray glass cleaner
directly on the HUD lens because the cleaner could
leak inside the unit and cause damage.
If the ignition is on and you cannot see the HUD image,
check to see if:
Something is covering the HUD unit.
The brightness is adjusted properly.
The HUD image is adjusted to the proper height.
Ambient light in the direction your vehicle is
facing is low.
A fuse is blown. SeeFuses and Circuit Breakers
on page 5-117.The windshield is part of the HUD system.
SeeWindshield Replacement on page 5-55.
The following Adaptive Cruise Control message
may appear in the HUD:
The PEDAL APPLIED ACC OVERRIDE message
indicates that you are pressing your foot on the
accelerator pedal and overriding Adaptive Cruise
Control. While this is being done, the system will not
automatically apply the brakes. Once you remove
your foot from the accelerator pedal, Adaptive Cruise
Control will return to normal operation and be able
to apply the brakes, if needed.
An Adaptive Cruise Control active symbol, alert symbol
or vehicle ahead symbol may also appear. SeeAdaptive
Cruise Control on page 3-20for more information.
Accessory Power Outlet(s)
Your vehicle is equipped with accessory power outlets.
The outlets can be used to plug in electrical equipment
such as a cellular telephone, CB radio, etc.
Your vehicle has one outlet in front of the center
console, one in the center console lid and there may be
an additional outlet in the rear of the center console.
Your vehicle may have a small cap that must be
removed to access the accessory power outlet.
If it does, when not using the outlet be sure to cover
it with the protective cap.

Brake System Warning Light
Your vehicle’s hydraulic brake system is divided into
two parts. If one part isn’t working, the other part can
still work and stop you. For good braking, though,
you need both parts working well.
If the warning light comes on, there is a brake problem.
Have your brake system inspected right away.
This light should come on briey when you turn the
engine on. If it does not come on then, have it xed so
it will be ready to warn you if there is a problem.When the ignition is on, the brake system warning light
will also come on when you set your parking brake.
The light will stay on if your parking brake does
not release fully. If it stays on after your parking brake
is fully released, it means you have a brake problem.
If the light comes on while you are driving, pull off
the road and stop carefully. You may notice that the
pedal is 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 4-31.
{CAUTION:
Your brake system may not be working
properly if the brake system warning light is
on. Driving with the brake system warning
light on can lead to an accident. If the light
is still on after you have pulled off the road
and stopped carefully, have the vehicle towed
for service. United StatesCanada

Antilock Brake System
Warning Light
For vehicles with the
Antilock Brake System
(ABS), this light will come
on briey when you
start the engine.
That is normal. If the light does not come on then, have it
xed so it will be ready to warn you if there is a problem.
If the ABS light stays on, turn the ignition off, if the light
comes on when you are 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 still
stays on, or comes on again while you are driving,
your vehicle needs service. If the regular brake system
warning light is not on, you still have brakes, but
you do not have antilock brakes. If the regular brake
system warning light is also on, you do not have antilock
brakes and there is a problem with your regular
brakes. SeeBrake System Warning Light on page 3-64
For vehicles with a Driver Information Center (DIC),
seeDIC Warnings and Messages on page 3-80for
all brake related DIC messages.
Traction Control System (TCS)
Warning Light
If the Traction Control
System (TCS) warning
light comes on and stays
on, there may be a
problem with the TCS.
The TCS warning light will come on briey when the
engine is started. If it does not come on then, have it
xed so it will be ready to warn you if there is a problem.
The light will also come on if you turn the TCS off using
the traction control on/off button located on the console.
If this light stays on or comes on while you are driving,
pull off the road as soon as possible and stop carefully.
Turn your engine off and then restart it. If the light still
stays on or comes back on again while you are driving,
your vehicle needs service. Have the TCS inspected as
soon as possible. SeeTraction Control System (TCS)
