Ending Cruise Control
There are three ways to end cruise
control:
.Step lightly on the brake pedal.
.Press*.
.PressJ.
Erasing Speed Memory
The cruise control set speed is
erased from memory if
Jis
pressed or if the ignition is
turned off.
Adaptive Cruise Control
For vehicles with Adaptive Cruise
Control (ACC), it allows the driver to
select the cruise control set speed
and following gap. Read this entire
section before using this system.
The following gap is the distance
between your vehicle and a
vehicle-detected directly ahead in
your path. If no vehicle is detected
in your path, ACC works like regular
cruise control. ACC uses camera and radar sensors. See
Radio
Frequency Statement on
page 13‑15 for information
regarding Part 15 of the Federal
Communications Commission (FCC)
rules and Industry Canada
Standards RSS-GEN/210/220/310.
If a vehicle is detected in your path,
ACC can apply acceleration or
limited, moderate braking to
maintain the selected following gap.
To disengage ACC, apply the brake.
If ACC is controlling your vehicle
speed when the traction control
system (TCS) activates, the ACC
will automatically disengage. See
Traction Control System (TCS) on
page 9‑28. When road conditions
allow ACC to be safely used, the
ACC can be turned back on.
{WARNING
ACC has limited braking ability
and may not have time to slow
the vehicle down enough to avoid
(Continued)
WARNING (CONTINUED)
a collision with another vehicle
you are following. This can occur
when vehicles suddenly slow or
stop ahead, enter your lane,
or cross the vehicle’s path. Also
see“Alerting the Driver” in this
section. Complete attention is
always required while driving and
you should be ready to take
action and apply the brakes. See
Defensive Driving on page 9‑3.
{WARNING
Adaptive Cruise Control will not
detect or brake for children,
pedestrians, animals, or other
objects.

9-38 Driving and Operating
Alerting the Driver
If ACC is engaged, driver action
may be required when:
.ACC cannot apply sufficient
braking because of approaching
a vehicle too rapidly.
.A temporary condition prohibits
ACC from operating. See
Vehicle Messages on page 5‑34.
.A malfunction is detected in the
system. SeeVehicle Messages
on page 5‑34.
When any of these conditions occur,
the collision alert symbol on the
HUD (if equipped) will flash on the
windshield. Either eight beeps will
sound from the front, or both sides
of the Safety Alert Seat will pulse five times. See
“Collision/Detection
Systems” underVehicle
Personalization on page 5‑44.
See Defensive Driving on page 9‑3.
Approaching and Following a
Vehicle
The vehicle ahead symbol is located
in the HUD display.
The vehicle ahead symbol only
displays when a vehicle is detected
in your vehicle’s path.
If this symbol is not displaying, ACC
will not respond to or brake to
vehicles ahead.
ACC automatically slows the vehicle
down and adjusts vehicle speed to
follow the vehicle in front at the
selected follow gap. The vehicle
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, the brake
lights will come on. The automatic
braking may feel or sound different
than if the brakes were applied
manually. This is normal.
Stationary or Very Slow-Moving
Objects
{WARNING
Adaptive Cruise Control (ACC)
may not detect and react to
stopped or slow-moving vehicles
ahead of you. For example, the
system will not brake for a vehicle
that it has never detected moving.
This can occur when a detected
vehicle changes lanes at an
intersection or in stop-and-go
traffic and then a stopped or
slow-moving vehicle appears.
Your vehicle may not stop and
could cause a crash. Use caution
(Continued)

Driving and Operating 9-39
WARNING (CONTINUED)
when using ACC. Your complete
attention is always required while
driving and you should be ready
to take action and apply the
brakes.
ACC Automatically Disengages
ACC may automatically disengage
and the driver will need to manually
apply the brakes to slow the
vehicle when:
.The sensors are blocked.
.There is no traffic or other
objects to detect.
.There is a fault in the system.
The ACC active symbol will not be
displayed when ACC is no longer
active. Notification to Resume ACC
ACC will maintain a follow gap
behind a detected vehicle and slow
your vehicle to a stop behind that
vehicle.
If the vehicle ahead has driven
away and ACC has not resumed,
the vehicle ahead symbol will flash
as a reminder. In addition, the left
and right sides of the Safety Alert
Seat will pulse three times, or three
beeps will sound. See
”Alert Type”
and “Go Notifier” in“Collision/
Detection Systems” underVehicle
Personalization on page 5‑44.
When the vehicle ahead drives
away, press RES+ or the
accelerator pedal to resume cruise
control. If stopped for more than
two minutes or if the driver door is
opened and the driver safety belt is
unbuckled, the ACC automatically
applies the electric parking brake to
hold the vehicle. The electric
parking brake status light will turn
on. See Electric Parking Brake on
page 9‑26. To resume ACC and release the electric parking brake,
press the accelerator pedal and
then RES+.
{WARNING
If ACC has stopped the vehicle,
and if ACC is disengaged, turned
off, or canceled, the vehicle will
no longer be held at a stop. The
vehicle can move. When ACC is
holding the vehicle at a stop,
always be prepared to manually
apply the brakes.
{WARNING
Leaving the vehicle without
placing it in P (Park) can be
dangerous. Do not leave the
vehicle while it is being held at a
stop by ACC. Always place the
vehicle in P (Park) and turn off
the ignition before leaving the
vehicle.

9-44 Driving and Operating
Displayed images may be farther or
closer than they appear. The area
displayed is limited and objects that
are close to either corner of the
bumper or under the bumper do not
display.
A warning triangle may display on
the RVC screen to show where the
Ultrasonic Rear Parking Assist
(URPA) has detected an object. This
triangle changes from amber to red
and increases in size the closer the
object.
On vehicles with the Rear Cross
Traffic Alert (RCTA), this triangle
with an arrow may also display on
the RVC screen to warn of traffic
coming from either direction. This
system detects objects coming from
up to 30 m (98 ft) from the left or
right side of the vehicle. When an
object is detected, either three
beeps sound or three Safety Alert
Seat pulses occur on the left or right
side, depending on the direction of
the detected vehicle.With URPA, as the vehicle backs up
at speeds of less than 8 km/h
(5 mph), the sensors on the rear
bumper detect objects up to 2.5 m
(8 ft) behind the vehicle that are
within a zone 25 cm (10 in) high off
the ground and below bumper level.
{WARNING
The parking assist system does
not detect children, pedestrians,
bicyclists, animals, or objects
located below the bumper or that
are too close or too far from the
vehicle. It is not available at
speeds greater than 8 km/h
(5 mph). To prevent injury, death,
or vehicle damage, even with
parking assist, always check the
area around the vehicle and
check all mirrors before moving
forward or backing.The instrument cluster parking
assist display has bars that show
“distance to object”
and object
location information for URPA, and
on some vehicles, the Front Parking
Assist system. As the object gets
closer, more bars light up. When an
object is first detected in the rear,
one beep will be heard from the
rear, or both sides of the Safety
Alert Seat will pulse two times.
When an object is very close
(<0.6 m (2 ft) in the vehicle rear,
or <0.3 m (1 ft) in the vehicle front),
five beeps will sound from the front
or rear, or both sides of the Safety
Alert Seat will pulse five times.

SBZA Detection Zones
The SBZA sensor covers a zone of
approximately one lane over from
both sides of the vehicle, or 3.5 m
(11 ft). This zone starts at each side
mirror and goes back approximately
5 m (16 ft). The height of the zone is
approximately between 0.5 m (1.5 ft)
and 2 m (6 ft) off the ground.
Use caution while changing lanes
when towing a trailer, as the SBZA
detection zones do not change to
become longer when a trailer is
towed.
How the System Works
The SBZA symbol lights up in the
side mirrors when the system
detects a vehicle in the side blind
zone, indicating it may be unsafe to
change lanes. Before making a lane
change, check the SBZA display,
check mirrors, glance over your
shoulder, and use the turn signals.
Left Side MirrorDisplayRight Side Mirror Display
When the vehicle is started, both
outside mirror SBZA displays will
briefly come on to indicate the
system is operating. When the
vehicle is moving forward, the left-
or right-side mirror display will light
up if a vehicle is detected in that
blind zone. If the turn signal is
activated and a vehicle is also
detected on the same side, the
display will flash as an extra
warning not to change lanes.
SBZA displays may come on when
a passed vehicle remains in or
drops back into the detection zone.
SBZA can be disabled through
vehicle personalization. See
“Collision/Detection Systems” under
Vehicle Personalization on page 5‑44. If SBZA is disabled by
the driver, the SBZA mirror displays
will not light up.
When the System Does Not
Seem to Work Properly
SBZA may not always alert the
driver to vehicles in the blind zone,
especially in wet conditions. The
system does not need to be
serviced. The system may light up
due to guardrails, signs, trees,
shrubs, and other non-moving
objects. This is normal system
operation; the vehicle does not need
service.
SBZA may not operate when the
SBZA sensors in the left or right
corners of the rear bumper are
covered with mud, dirt, snow, ice,
or slush, or in heavy rainstorms. For
cleaning instructions, see "Washing
the Vehicle" under
Exterior Care on
page 10‑76. If the DIC still displays
the SIDE DETECTION SYSTEM
UNAVAILABLE message after
cleaning the rear bumper corners,
see your dealer.

Driving and Operating 9-53
If the SBZA displays do not light up
when vehicles are in the blind zone
and the system is clean, the system
may need service. Take the vehicle
to your dealer.
The SBZA displays may remain on
if a trailer is attached to the vehicle,
or if a bicycle or object is extending
out to either side of the vehicle.
When SBZA is disabled for any
reason other than the driver turning
it off, the Side Blind Zone Alert On
option will not be available on the
personalization menu.

Lane Departure
Warning (LDW)
LDW may help avoid crashes due to
unintentional lane departures. It may
provide a warning if the vehicle is
crossing a lane without using a turn
signal. LDW uses a camera sensor
to detect the lane markings. It only
operates at speeds of 56 km/h (35
mph) or greater.
When the vehicle crosses a
detected lane marking, the LDW
indicator will flash and either three
beeps sound or three Safety Alert
Seat pulses will occur on the left or
right side of the seat, depending on
the lane departure direction. LDW
will not warn if the turn signal is on
or if a sharp maneuver is made.
{WARNING
The LDW system is an aid to help
the vehicle stay in the driving
lane. It does not steer the vehicle.
The LDW system may not:
.Provide enough time to avoid
a crash.
.Detect lane markings under
bad weather conditions or if
the windshield is dirty.
.Detect lane markings and will
not detect road edges.
.Warn that the vehicle is
crossing a lane marking if the
system does not detect the
lane marking.
If LDW only detects lane
markings on one side of the road,
it will only warn you when
departing the lane on the side
where it has detected a lane
marker. Even with LDW, always
keep your attention on the road (Continued)

Black plate (54,1)Cadillac XTS Owner Manual - 2013 - 1st - 4/13/12
9-54 Driving and Operating
WARNING (CONTINUED)
and maintain proper vehicle
position within the lane, or vehicle
damage, injury, or death could
occur. Always keep the
windshield clean and do not use
LDW in bad weather conditions.
How the System Works
The LDW camera sensor is on the
windshield ahead of the rearview
mirror.
To turn LDW on and off, press
@on
the center stack to the left of the
infotainment screen. The control
indicator will light when LDW is on.
When the vehicle is started, the
LDW indicator on the instrument
cluster will come on briefly.
If LDW is on, the LDW indicator will
appear green if the system detects
a left or right lane marking. If the
vehicle crosses a detected lane
marking without using the turn
signal, this indicator will change to
amber and flash. In addition, three
beeps will be sounded from the left
or right speaker, or the Safety Alert
Seat will pulse three times on either
the left or right side of the seat,
depending on the lane departure
direction.
When the System Does Not
Seem to Work Properly
If the LDW symbol does not appear:
.The lane markings on the road
may not be seen.
.The camera sensor may be
blocked by dirt, snow, or ice.
.The windshield may be
damaged.
.The weather may be limiting
visibility.
This is normal operation; the vehicle
does not need service. Clean the
windshield.
Lane markings may not be detected
on curves, highway exit ramps,
or hills; or due to poor visibility.
If the LDW camera system does not
seem to operate properly, cleaning
the outside of the windshield in front
of the camera sensor may correct
the issue.
{WARNING
If the LDW camera sensor is
blocked by dirt, snow, or ice, or if
the headlamps are not cleaned or
properly aimed, or if the
windshield is dirty or damaged, it
may not detect the lanes ahead.
LDW may not help avoid a crash
under these conditions. Keep the
headlamps cleaned and properly
aimed and the windshield clean.
