2011 CADILLAC STS brake light

Black plate (15,1)Cadillac STS Owner Manual - 2011
When going downhill, you might have to brake to keep
the vehicle speed down. When the brakes are applied
the cruise control is disengaged.
Ending Cruise Control
There are three ways to end cruise control.
.To disengage cruise control; step lightly on the
brake pedal.
.Press the[button on the steering wheel.
.To turn off cruise control, move the cruise control
switch to
9.
Erasing Speed Memory
The cruise control set speed is erased from memory by
moving the cruise control switch to
9or if the ignition
is turned off.
Adaptive Cruise Control
If the vehicle has adaptive cruise control, read the
Radio Frequency Statementon page 8‑20before using
this feature.
Changes or modifications 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
be reset. Adaptive Cruise Control uses radar to
detect a vehicle directly ahead in your path, within a
distance of 100 m (328 ft), and operates at speeds
above 48 km/h (30 mph). When it is engaged by
the driver, the system can apply limited braking or
acceleration of the vehicle, automatically, to maintain
a selected following distance to the vehicle ahead.

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 briefly,
Adaptive Cruise Control will not respond to vehicles you
may see ahead.
{WARNING:
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.

Twilight Sentinel®
Twilight Sentinel®can turn the 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 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. See Instrument Panel Brightness
on
page 4‑35for 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.

Brake System Warning Light
The vehicle brake system consists of two hydraulic
circuits. If one circuit is not working, the remaining
circuit can still work to stop the vehicle. For normal
braking performance, both circuits need to be working
If the warning light comes on, there is a brake problem.
Have the brake system inspected right away.
EnglishMetric
This light comes on briefly when the engine is turned
on. If it does not come on then, have it fixed 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 floor. It may take longer to
stop. If the light is still on, have the vehicle towed for
service. See
Towing Your Vehicle on page 5‑29.
{WARNING:
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.

Antilock Brake System (ABS)
Warning Light
For vehicles with the
Antilock Brake System
(ABS), this light comes on
briefly when the engine is
started.
If it does not, have the vehicle serviced by your dealer.
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. See
Brake System
Warning Light on page 4‑58.
For vehicles with a Driver Information Center (DIC),
see DIC Warnings and Messages
on page 4‑76for

Braking
SeeBrake System Warning Light on page 4‑58.
Braking action involves perception time and reaction
time. Deciding to push the brake pedal is perception
time. Actually doing it is reaction time.
Average reaction time is about three‐fourths of a
second. But that is only an average. It might be less
with one driver and as long as two or three seconds or
more with another. Age, physical condition, alertness,
coordination, and eyesight all play a part. So do alcohol,
drugs, and frustration. But even in three‐fourths of a
second, a vehicle moving at 100 km/h (60 mph) travels
20 m (66 feet). That could be a lot of distance in an
emergency, so keeping enough space between the
vehicle and others is important.
And, of course, actual stopping distances vary greatly
with the surface of the road, whether it is pavement or
gravel; the condition of the road, whether it is wet, dry,
or icy; tire tread; the condition of the brakes; the weight
of the vehicle; and the amount of brake force applied. Avoid needless heavy braking. Some people drive in
spurts, heavy acceleration followed by heavy braking,
rather than keeping pace with traffic. This is a mistake.
The brakes might not have time to cool between hard
stops. The brakes will wear out much faster with a lot
of heavy braking. Keeping pace with the traffic and
allowing realistic following distances eliminates a lot of
unnecessary braking. That means better braking and
longer brake life.
If the engine ever stops while the vehicle is being
driven, brake normally but do not pump the brakes.
If the brakes are pumped, the pedal could get harder to
push down. If the engine stops, there will still be some
power brake assist but it will be used when the brake is
applied. Once the power assist is used up, it can take
longer to stop and the brake pedal will be harder
to push.
Adding non‐dealer/non‐retailer accessories can affect
vehicle performance. See
Accessories and
Modifications on page 6‑4.
