Cadillac CTS/CTS-V Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
11349156) - 2018 - CRC - 9/29/17
236 DRIVING AND OPERATING
FAB may slow the vehicle to a
complete stop to try to avoid a
potential crash. If this happens, FAB
may engage the Electric Parking Brake
(EPB) to hold the vehicle at a stop. To
release automatic braking, release the
EPB or firmly press the accelerator
pedal.
{Warning
FAB may automatically brake the
vehicle suddenly in situations
where it is unexpected and
undesired. It could respond to a
turning vehicle ahead, guardrails,
signs, and other non-moving
objects. To override FAB, firmly
press the accelerator pedal, if it is
safe to do so.
Intelligent Brake Assist (IBA)
IBA may activate when the brake
pedal is applied quickly by providing a
boost to braking based on the speed
of approach and distance to a vehicle
ahead.Minor brake pedal pulsations or pedal
movement during this time is normal
and the brake pedal should continue
to be applied as needed. IBA will
automatically disengage only when
the brake pedal is released.
{Warning
IBA may increase vehicle braking in
situations when it may not be
necessary. You could block the flow
of traffic. If this occurs, take your
foot off the brake pedal and then
apply the brakes as needed.
FAB and IBA can be disabled through
vehicle personalization. See “Collision/
Detection Systems” underVehicle
Personalization 0144.
{Warning
Using FAB or IBA while towing a
trailer could cause you to lose
control of the vehicle and crash.
Turn the system to Off when
towing a trailer.
Side Blind Zone
Alert (SBZA)
If equipped, the SBZA system is a
lane-changing aid that assists drivers
with avoiding crashes that occur with
moving vehicles in the side blind zone
(or spot) areas. When the vehicle is in
a forward gear, the left or right side
mirror display will light up if a moving
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. Since
this system is part of the Lane Change
Alert (LCA) system, read the entire
LCA section before using this feature.
Lane Change Alert (LCA)
If equipped, the LCA system is a
lane-changing aid that assists drivers
with avoiding lane change crashes
that occur with moving vehicles in the
side blind zone (or spot) areas or with
vehicles rapidly approaching these
areas from behind. The LCA warning

Cadillac CTS/CTS-V Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
11349156) - 2018 - CRC - 9/29/17
DRIVING AND OPERATING 237
display will light up in the
corresponding outside side mirror and
will flash if the turn signal is on.
{Warning
LCA does not alert the driver to
vehicles outside of the system
detection zones, pedestrians,
bicyclists, or animals. It may not
provide alerts when changing lanes
under all driving conditions. Failure
to use proper care when changing
lanes may result in injury, death,
or vehicle damage. Before making a
lane change, always check mirrors,
glance over your shoulder, and use
the turn signals.LCA Detection Zones
1. SBZA Detection Zone
2. LCA Detection Zone
The LCA sensor covers a zone of
approximately one lane over from
both sides of the vehicle, or 3.5 m
(11 ft). The height of the zone is
approximately between 0.5 m (1.5 ft)
and 2 m (6 ft) off the ground. The Side
Blind Zone Alert (SBZA) warning area
starts at approximately the middle of
the vehicle and goes back 5 m (16 ft).
Drivers are also warned of vehicles
rapidly approaching from up to 25 m
(82 ft) behind the vehicle.
How the System Works
The LCA symbol lights up in the side
mirrors when the system detects a
moving vehicle in the next lane over
that is in the side blind zone or
rapidly approaching that zone from
behind. A lit LCA symbol indicates it
may be unsafe to change lanes. Before
making a lane change, check the LCA
display, check mirrors, glance over
your shoulder, and use the turn
signals.
Left Side Mirror
DisplayRight Side Mirror Display
When the vehicle is started, both
outside mirror LCA displays will
briefly come on to indicate the system
is operating. When the vehicle is in a
forward gear, the left or right side
mirror display will light up if a moving
vehicle is detected in the next lane
over in that blind zone or rapidly
approaching that zone. If the turn

11349156) - 2018 - CRC - 9/29/17
238 DRIVING AND OPERATING
signal is activated in the same
direction as a detected vehicle, this
display will flash as an extra warning
not to change lanes.
LCA can be disabled through vehicle
personalization. See“Collision/
Detection Systems” underVehicle
Personalization 0144. If LCA is
disabled by the driver, the LCA mirror
displays will not light up.
When the System Does Not
Seem to Work Properly
The LCA system requires some driving
for the system to calibrate to
maximum performance. This
calibration may occur more quickly if
the vehicle is driven on a straight
highway road with traffic and roadside
objects (e.g., guardrails, barriers).
During a trip, the LCA system is not
operational until the vehicle first
reaches a speed of 24 km/h (15 mph).
LCA displays may not come on when
passing a vehicle quickly, for a
stopped vehicle, or when towing a
trailer. The LCA detection zones that
extend back from the side of the
vehicle do not move further back when a trailer is towed. Use caution
while changing lanes when towing a
trailer. LCA may alert to objects
attached to the vehicle, such as a
trailer, bicycle, or object extending out
to either side of the vehicle. Attached
objects may also interfere with the
detection of vehicles. This is normal
system operation; the vehicle does not
need service.
LCA may not always alert the driver to
vehicles in the next lane over,
especially in wet conditions or when
driving on sharp curves. 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.
LCA may not operate when the LCA
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 Care0329.
If the DIC still displays the system
unavailable message after cleaning both sides of the vehicle toward the
rear corners of the vehicle, see your
dealer.
If the LCA displays do not light up
when moving vehicles are in the side
blind zone or rapidly approaching this
zone and the system is clean, the
system may need service. Take the
vehicle to your dealer.
When LCA is disabled for any reason
other than the driver turning it off,
the Lane Change Alert On option will
not be available on the
personalization menu.
Radio Frequency Information
See
Radio Frequency Statement 0367.
Lane Departure
Warning (LDW)
If equipped, LDW may help avoid
crashes due to unintentional lane
departures. It may provide a warning
if the vehicle is crossing a detected
lane marking without using a turn
signal in the lane departure direction.
Since this system is part of the Lane

Cadillac CTS/CTS-V Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
11349156) - 2018 - CRC - 9/29/17
240 DRIVING AND OPERATING
To turn LKA on and off, pressA
on the center stack.
When on,
Ais green if LKA is
available to assist and provide LDW
alerts. It may assist by gently turning
the steering wheel and display
A
as amber if the vehicle approaches a
detected lane marking without
using a turn signal in that direction.
It may also provide an LDW alert by
flashing
Aamber as the lane
marking is crossed. Additionally, there
may be three beeps, or the driver seat
may pulse three times, on the right or
left, depending on the lane departure
direction.
Take Steering
The LKA system does not
continuously steer the vehicle. If LKA
does not detect active driver steering,
an alert, chime, or DIC message may
be provided. Move the steering wheel
to dismiss.
When the System Does Not
Seem to Work Properly
The system performance may be
affected by:
. Close vehicles ahead.
. Sudden lighting changes, such as
when driving through tunnels.
. Banked roads.
. Roads with poor lane markings,
such as two-lane roads.
If the LKA system is not functioning
properly when lane markings are
clearly visible, cleaning the windshield
may help.
A camera blocked message may
display if the camera is blocked.
Cleaning the outside of the windshield
behind the rearview mirror may
correct the issue. Some driver
assistance systems may have reduced
performance or not work at all. An
LKA or LDW unavailable message may
display if the systems are temporarily
unavailable. This message could be
due to a blocked camera. The LKA system does not need service. Clean
the outside of the windshield behind
the rearview mirror.
LKA assistance and/or LDW alerts
may occur due to tar marks, shadows,
cracks in the road, temporary or
construction lane markings, or other
road imperfections. This is normal
system operation; the vehicle does not
need service. Turn LKA off if these
conditions continue.
Vehicle-to-Vehicle
If equipped and travelling in the U.S.
or Canada, Vehicle-to-Vehicle (V2V)
can communicate with other
V2V-equipped vehicles to send and
receive vehicle location, speed,
direction, and notices regarding
certain traffic situations from up to
approximately 300 m (980 ft) away.
Under certain conditions, V2V may
provide notice of certain traffic
situations, such as when other
V2V-equipped vehicles ahead may be
braking hard, disabled, on slippery
roads, or in a crash.

Without Head-Up Display
When a detected vehicle is braking
extremely hard, rapid beeps or seat
pulses may also occur.
To enable or disable this feature, see
“Connected Vehicle Braking Alert ”
under Vehicle Personalization 0144.
V2V Disabled Vehicle Ahead
When the vehicle is traveling above
20 km/h (13 mph), V2V may detect
when a V2V-equipped vehicle ahead
has a deployed airbag. When the
vehicle is traveling above 60 km/h
(38 mph), V2V may detect when a
V2V-equipped vehicle ahead has
warning flashers active and is moving
slowly or has stopped. Under these
disabled vehicle conditions, V2V may
display the DIC message HAZARD
LIGHTS AHEAD and the estimated
distance to the vehicle. A chime or two seat pulses may also
occur.
TRAFFIC INFORMATION OFF
This message displays when the V2V
Disabled Vehicle Ahead feature has
been turned off.
To enable or disable this feature, see
“Traffic and Roadside Information
”
under Vehicle Personalization 0144.
V2V Slippery Road Ahead
When the vehicle is traveling above
32 km/h (20 mph), V2V may detect
when a V2V-equipped vehicle ahead
has a StabiliTrak, Traction Control,
or Antilock Brake System (ABS) event.
This could indicate that the road
ahead is slippery or has low traction.
Under these conditions, V2V may
display a DIC message.
TRAFFIC INFORMATION OFF
This message displays when the V2V
Slippery Road Ahead feature has been
turned off.
To enable or disable this feature, see
