2005 CADILLAC STS brake light

While using the DSC feature the vehicle will have rmer
shifting and increased performance. You can use this
for sport driving or when climbing hills to stay in
gear longer or to down shift for more power or engine
braking.
The transmission will only allow you to shift into gears
appropriate for the vehicle speed and rpm. The
transmission will not automatically shift to the next
higher gear if the engine rpm is too high.
All-Wheel Drive
If your vehicle is equipped with this feature, engine
power is sent to all four wheels all the time.
This is like four-wheel drive, but it is fully automatic.
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. See
Brake System Warning Light on page 3-64for more
information.
2-29

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 pedal will follow it to the released
position.
Notice:Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Verify 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.

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 you want.
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
will come on while
cruise control is on.
Resuming a Set Speed
Suppose you set your cruise control at a desired speed
and then you apply the brake. This, of course,
disengages the cruise control. But you don’t need to
reset it.
Once you’re going about 25 mph (40 km/h) or more, you
can move the cruise control switch briey from on to
resume/accelerate.
You’ll 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. So unless you want to go faster, don’t
hold the switch at resume/accelerate.
3-18

Using Cruise Control on Hills
How well your cruise control will work on hills depends
upon your speed, load and the steepness of the
hills. When going up steep hills, you may have to step
on the accelerator pedal to maintain your speed.
When going downhill, you may have to brake to keep
your speed down. Applying the brake will take you out of
cruise control. If you need to apply the brake due to
the grade of the downhill slope, you may 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 you turn off the cruise control or the ignition, your
cruise control set speed memory is erased.
Adaptive Cruise Control
If your vehicle has this feature, be sure to read this
entire section before using it.The system operates on a radio frequency subject to
Federal Communications Commission (FCC) Rules and
with Industry Canada.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
1. This device may not cause interference, and
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.
This device complies with RSS-210 of Industry Canada.
Operation is subject to the following two conditions:
1. This device may not cause interference, and
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.
Changes or modications to this system by other than
an authorized service facility could void authorization to
use this equipment.
Adaptive Cruise Control is an enhancement to
traditional cruise control and is not a safety system.
It allows you to keep cruise control engaged in moderate
traffic conditions without having to constantly reset
your cruise control. Adaptive Cruise Control uses
radar to detect a vehicle directly ahead in your
path, within a distance of 328 ft (100 m), and
operates at speeds above 25 mph (40 km/h).
3-20

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 will, automatically, slow your
vehicle down when approaching a slower moving
vehicle. It will then adjust your speed to follow the
vehicle in front at the selected follow distance. Your
speed will increase or decrease 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 will come on. It may feel or
sound different than if you were applying the brakes
yourself. This is normal.

Twilight Sentinel®
Twilight Sentinel®can turn your lamps on and off for you.
A light sensor on top of the instrument panel makes the
Twilight Sentinel
®work, so be sure it is not covered.
With Twilight Sentinel
®you will see the following
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 you start your vehicle in a dark garage, the automatic
headlamp system will come on immediately. Once
you leave the garage, it will take approximately
one minute for the automatic headlamp system to
change to DRL if it is light outside. During that delay,
your instrument panel cluster may not be as bright
as usual. Make sure your instrument panel brightness
control is in full bright position. SeeInstrument Panel
Brightness on page 3-41for 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/ACC. Then start the vehicle. The
lamps will stay off until you release the parking
brake.
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, your lamps
will remain on until:
The exterior lamp switch is moved from off to the
parking lamp position, or
a delay time that you select has elapsed.

Polarized sunglasses could make the HUD image
harder to see.
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 5-95.
Keep in mind that your windshield is part of the HUD
system. SeeWindshield Replacement on page 5-51.
The following Adaptive Cruise Control message
may appear in the HUD:
PEDAL APPLIED ACC OVERRIDE:This message
indicates that you are pressing your foot on the
accelerator pedal and overriding Adaptive Cruise
Control. While you are doing this, 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.
You may also see an Adaptive Cruise Control active
symbol, alert symbol or vehicle ahead symbol. See
Adaptive Cruise Control on page 3-20for more
information.
