ACC may detect a vehicle that is not in your lane and
apply the brakes.
ACC may, occasionally, provide a driver alert and/or
braking that you consider unnecessary. It could respond
to signs, guardrails, and other stationary objects when
entering or exiting a curve. This is normal operation.
Your vehicle does not need service.
Highway Exit Ramps
{WARNING:
Adaptive Cruise Control may lose track of the
vehicle ahead and accelerate up to your set
speed while entering or on highway exit ramps.
You could be startled by this acceleration and
even lose control of the vehicle. Disengage
Adaptive Cruise Control before entering a
highway exit ramp. Do not use Adaptive Cruise
Control while entering or on exit ramps.
Other Vehicle Lane Changes
If another vehicle enters the same lane as you, ACC will
not detect the vehicle until it is completely in the lane.
Be ready to take action and apply the brakes yourself.

Using ACC on Hills and When Towing a
Trailer
How well ACC will work on hills and when towing a
trailer depends on your vehicle's speed, vehicle load,
traffic conditions and the steepness of the hills. It may
not detect a vehicle in your lane while driving on hills.
When going up steep hills, you may want to use the
accelerator pedal to maintain your vehicle's speed.
When going downhill, especially when towing a trailer,
you may want to brake to keep your speed down.
Applying the brake disengages the system. You may
choose not to use ACC on steep hills, especially when
towing a trailer.
Disengaging ACC
To turn off the system, apply the brake pedal, press the
cancel button, or press the ACC button.
Erasing Set Speed Memory
Press the ACC button or turn the ignition off.
Other Messages
There are three additional messages that may appear
on the DIC. They are SERVICE RADAR CRUISE,
RADAR CRUISE NOT READY and CLEAN RADAR.
These messages will appear to indicate a problem
with the ACC. SeeDIC Warnings and Messages
on
page 4‑65for more information.
Cleaning the System
The radar can become blocked by snow, ice, or dirt.
If so, you may need to turn off the engine and clean the
lens. Remember, do not use ACC in icy conditions,
or when visibility is low, such as in fog, rain or snow.
The emblem/lens is located in the center of the grille.
To clean the emblem/lens, wipe the surface with a soft
cloth. After cleaning the emblem/lens, try to engage the
ACC. If you are unable to do so, see your dealer.

For persons under 21, it is against the law in every
U.S. state to drink alcohol. There are good medical,
psychological, and developmental reasons for
these laws.
The obvious way to eliminate the leading highway
safety problem is for people never to drink alcohol and
then drive.
Medical research shows that alcohol in a person's
system can make crash injuries worse, especially
injuries to the brain, spinal cord, or heart. This means
that when anyone who has been drinking—driver or
passenger —is in a crash, that person's chance of
being killed or permanently disabled is higher than if the
person had not been drinking.
Control of a Vehicle
The following three systems help to control the vehicle
while driving —brakes, steering, and accelerator. At
times, as when driving on snow or ice, it is easy to ask
more of those control systems than the tires and road
can provide. Meaning, you can lose control of the
vehicle. See Traction Control System (TCS)
on
page 5‑6.
Adding non‐dealer accessories can affect vehicle
performance. See Accessories and Modifications
on
page 6‑3.
Braking
See Brake System Warning Light on page 4‑50.
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.

Black plate (4,1)Cadillac DTS Owner Manual - 2011
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 accessories can affect vehicle
performance. SeeAccessories and Modifications
on
page 6‑3.
Antilock Brake System (ABS)
This vehicle has the Antilock Brake System (ABS), an
advanced electronic braking system that helps prevent
a braking skid.
When the engine is started and the vehicle begins to
drive away, ABS checks itself. A momentary motor or
clicking noise might be heard while this test is going on,
and it might even be noticed that the brake pedal
moves a little. This is normal.
If there is a problem with
ABS, this warning light
stays on. See Antilock
Brake System (ABS)
Warning Light
on
page 4‑51.
Let us say the road is wet and you are driving safely.
Suddenly, an animal jumps out in front of you. You slam
on the brakes and continue braking. Here is what
happens with ABS:
A computer senses that the wheels are slowing
down. If one of the wheels is about to stop rolling, the
computer will separately work the brakes at each front
wheel and at both rear wheels.
5-4

Black plate (5,1)Cadillac DTS Owner Manual - 2011
ABS can change the brake pressure to each wheel, as
required, faster than any driver could. This can help the
driver steer around the obstacle while braking hard.
As the brakes are applied, the computer keeps
receiving updates on wheel speed and controls braking
pressure accordingly.
Remember: ABS does not change the time needed to
get a foot up to the brake pedal or always decrease
stopping distance. If you get too close to the vehicle in
front of you, there will not be enough time to apply the
brakes if that vehicle suddenly slows or stops. Always
leave enough room up ahead to stop, even with ABS.
Using ABS
Do not pump the brakes. Just hold the brake pedal
down firmly and let antilock work. The antilock pump or
motor operating might be heard and the brake pedal
might be felt to pulsate, but this is normal.
Braking in Emergencies
ABS allows the driver to steer and brake at the same
time. In many emergencies, steering can help more
than even the very best braking.
Brake Assist
This vehicle has a Brake Assist feature designed to
assist the driver in stopping or decreasing vehicle
speed in emergency driving conditions. This feature
uses the stability system hydraulic brake control module
to supplement the power brake system under conditions
where the driver has quickly and forcefully applied the
brake pedal in an attempt to quickly stop or slow down
the vehicle. The stability system hydraulic brake control
module increases brake pressure at each corner of
the vehicle until the ABS activates. Minor brake pedal
pulsations or pedal movement during this time is normal
and the driver should continue to apply the brake pedal
as the driving situation dictates The Brake Assist
feature will automatically disengage when the brake
pedal is released or brake pedal pressure is quickly
decreased.
