224 DRIVING AND OPERATING
When following a vehicle and entering
a curve, ACC may not detect the
vehicle ahead and accelerate to the set
speed. When this happens the vehicle
ahead indicator will not appear.
ACC may detect a vehicle that is not
in your lane and apply the brakes.ACC may occasionally provide an alert
and/or braking that is considered
unnecessary. It could respond to
vehicles in different lanes, signs,
guardrails, and other stationary
objects when entering or exiting a
curve. This is normal operation. The
vehicle does not need service.
Other Vehicle Lane Changes
ACC will not detect a vehicle ahead
until it is completely in the lane. The
brake may need to be manually
applied.
Do Not Use ACC on Hills and When
Towing a Trailer
Do not use ACC when driving on steep
hills or when towing a trailer. ACC will
not detect a vehicle in the lane while
driving on steep hills. The driver will
often need to take over acceleration
and braking on steep hills, especially
when towing a trailer. If the brakes are
applied, the ACC disengages.
Ending ACC
There are three ways to
disengage ACC:
.
Step lightly on the brake pedal.
. Press
*.
. Press

RCTA can also be turned on or off
through vehicle personalization. See
“Collision/Detection Systems”under
Vehicle Personalization 0144.
Automatic Parking Assist (APA)
If equipped, APA searches for and
steers the vehicle into parallel and
perpendicular parking spots. When
using APA, you must still shift gears,
and control the brakes and
accelerator. A display and audible
beeps help to guide parking
maneuvers.
{Warning
APA does not apply the brakes. APA
may not detect objects in the
parking space, objects that are soft
or narrow, objects high off the
ground such as flatbed trucks,
or objects below ground level such
as large potholes. Always verify that
the parking space is appropriate for
parking a vehicle. APA does not
respond to changes in the parking
space, such as movement of an
(Continued)
Warning (Continued)
adjacent vehicle, or a person or
object entering the parking space.
APA does not detect or avoid traffic
that is behind or alongside of the
vehicle. Always be prepared to stop
the vehicle during the parking
maneuver.
Press
Oon the center stack to
enable the system to search for a
parking space that is large enough and
within 1.5 m (5 ft) of the vehicle. The
vehicle speed must be below
30 km/h (18 mph). The system cannot:
. Detect whether it is a legal parking
space.
. Park exactly lined up with the
vehicle next to it if the spot is
approached at an angle or if the
parking space is angled.
. Park exactly centered in a spot
that is marked too large.
. Always detect short curbs. When enabled, APA searches for
parallel parking spaces to the right of
the vehicle. To search for a parking
space to the left, turn on the left turn
signal or, if available, change the side
selection in the infotainment display.
To switch the parking mode between
parallel and perpendicular, press and
hold
Oduring the search process or,
if available, change the parking mode
in the infotainment display.
After completely passing a large
enough space, an audible beep occurs
and a red stop symbol is displayed.
If the vehicle is in R (Reverse), but
does not steer into the expected
space, this may be because the system

DRIVING AND OPERATING 235
Following Distance Indicator
The following distance to a moving
vehicle ahead in your path is indicated
in following time in seconds on the
Driver Information Center (DIC). See
Driver Information Center (DIC)0137.
The minimum following time is
0.5 seconds away. If there is no vehicle
detected ahead, or the vehicle ahead is
out of sensor range, dashes will be
displayed.
Unnecessary Alerts
FCA may provide unnecessary alerts
for turning vehicles, vehicles in other
lanes, objects that are not vehicles,
or shadows. These alerts are normal
operation and the vehicle does not
need service.
Cleaning the System
If the FCA system does not seem to
operate properly, this may correct the
issue:
. Clean the outside of the
windshield in front of the rearview
mirror. .
Clean the entire front of the
vehicle.
. Clean the headlamps.
Forward Automatic
Braking (FAB)
If the vehicle has Adaptive Cruise
Control (ACC), it also has FAB, which
includes Intelligent Brake Assist (IBA).
When the system detects a vehicle
ahead in your path that is traveling in
the same direction that you may be
about to crash into, it can provide a
boost to braking or automatically
brake the vehicle. This can help avoid
or lessen the severity of crashes when
driving in a forward gear. Depending
on the situation, the vehicle may
automatically brake moderately or
hard. This forward automatic braking
can only occur if a vehicle is detected.
This is shown by the FCA vehicle
ahead indicator being lit. See Forward
Collision Alert (FCA) System 0232.
The system works when driving in a
forward gear above 4 km/h (2 mph).
It can detect vehicles up to
approximately 60 m (197 ft).
{Warning
FAB is an emergency crash
preparation feature and is not
designed to avoid crashes. Do not
rely on FAB to brake the vehicle.
FAB will not brake outside of its
operating speed range and only
responds to detected vehicles.
FAB may not: . Detect a vehicle ahead on
winding or hilly roads.
. Detect all vehicles, especially
vehicles with a trailer,
tractors, muddy vehicles, etc.
. Detect a vehicle when
weather limits visibility, such
as in fog, rain, or snow.
. Detect a vehicle ahead if it is
partially blocked by
pedestrians or other objects.
Complete attention is always
required while driving, and you
should be ready to take action and
apply the brakes and/or steer the
vehicle to avoid crashes.

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

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

DRIVING AND OPERATING 247
.Do not tow a trailer during the
first 2 414 km (1,500 mi) to
prevent damage to the engine,
axle, or other parts.
. Then during the first 800 km
(500 mi) of trailer towing, do not
drive over 80 km/h (50 mph) and
do not make starts at full throttle.
. Vehicles can tow in D (Drive). Shift
the transmission to a lower gear if
the transmission shifts too often
under heavy loads and/or hilly
conditions.
. Do not use Adaptive Cruise
Control when towing.
. The Forward Automatic Braking
System should be set to Off when
towing. See Forward Automatic
Braking (FAB) 0235.
. Turn off Parking Assist when
towing.{Warning
When towing a trailer, exhaust
gases may collect at the rear of the
vehicle and enter if the liftgate,
trunk/hatch, or rear-most window
is open.
When towing a trailer:
. Do not drive with the liftgate,
trunk/hatch, or rear-most
window open.
. Fully open the air outlets on
or under the instrument
panel.
. Also adjust the climate
control system to a setting
that brings in only outside air.
See “Climate Control Systems ”
in the Index.
For more information about carbon
monoxide, see Engine Exhaust
0 199.
Towing a trailer requires a certain
amount of experience. The
combination you are driving is longer and not as responsive as the vehicle
itself. Get acquainted with the
handling and braking of the rig before
setting out for the open road.
Before starting, check all trailer hitch
parts and attachments, safety chains,
electrical connectors, lamps, tires, and
mirrors. If the trailer has electric
brakes, start the combination moving
and then apply the trailer brake
controller by hand to be sure the
brakes work.
During the trip, check occasionally to
be sure that the load is secure and the
lamps and any trailer brakes
still work.
Following Distance
Stay at least twice as far behind the
vehicle ahead as you would when
driving the vehicle without a trailer.
This can help to avoid heavy braking
and sudden turns.
Passing
More passing distance is needed when
towing a trailer. The combination will
not accelerate as quickly and is longer

3. When the wheel chocks are inplace, release the regular brakes
until the chocks absorb the load.
4. Reapply the brake pedal. Then apply the parking brake and shift
into P (Park).
5. Release the brake pedal.
Leaving After Parking on a Hill
1. Apply and hold the brake pedal.
2. Start the engine.
3. Shift into a gear.
4. Release the parking brake.
5. Let up on the brake pedal.
6. Drive slowly until the trailer is clear of the chocks.
7. Stop and have someone pick up and store the chocks.
Maintenance when Trailer
Towing
The vehicle needs service more often
when pulling a trailer. See
Maintenance Schedule 0339. Things
that are especially important in trailer
operation are automatic transmission fluid, engine oil, axle lubricant, belts,
cooling system, and brake system. It is
a good idea to inspect these before
and during the trip.
Check periodically to see that all hitch
nuts and bolts are tight.
Trailer Towing (V6 Engine,
Non Twin Turbo)
Before pulling a trailer, there are three
important considerations that have to
do with weight:
.
The weight of the trailer.
. The weight of the trailer tongue.
. The total weight on your vehicle's
tires.
Weight of the Trailer
How heavy can a trailer safely be?
It should never weigh more than
454 kg (1,000 lb). But even that can be
too heavy.
It depends on how the rig is used. For
example, speed, altitude, road grades,
outside temperature, and how much
the vehicle is used to pull a trailer are all important. It can depend on any
special equipment on the vehicle, and
the amount of tongue weight the
vehicle can carry. See
“Weight of the
Trailer Tongue ”later in this section.
Maximum trailer weight is calculated
assuming only the driver is in the tow
vehicle and it has all the required
trailering equipment. The weight of
additional optional equipment,
passengers, and cargo in the tow
vehicle must be subtracted from the
maximum trailer weight.
Ask your dealer for trailering
information or advice.
Weight of the Trailer Tongue
The tongue load (1) of any trailer is an
important weight to measure because
it affects the total gross weight of the
vehicle. The Gross Vehicle Weight
(GVW) includes the curb weight of the
vehicle, any cargo carried in it, and
the people who will be riding in the
vehicle. If there are a lot of options,
equipment, passengers, or cargo in the
vehicle, it will reduce the tongue
weight the vehicle can carry, which
will also reduce the trailer weight the

To ensure proper engine performance
and long life, careful attention must
be paid to engine oil. Following these
simple, but important steps will help
protect your investment:
.
Use engine oil approved to the
proper specification and of the
proper viscosity grade. See
“Selecting the Right Engine Oil” in
this section.
. Check the engine oil level regularly
and maintain the proper oil level.
See “Checking Engine Oil” and
“When to Add Engine Oil” in this
section.
. Change the engine oil at the
appropriate time. See Engine Oil
Life System 0265.
. Always dispose of engine oil
properly. See “What to Do with
Used Oil” in this section.
Checking Engine Oil
Check the engine oil level regularly,
every 650 km (400 mi), especially prior
to a long trip. The engine oil dipstick handle is a loop. See
Engine
Compartment Overview 0256 for the
location.
{Warning
The engine oil dipstick handle may
be hot; it could burn you. Use a
towel or glove to touch the dipstick
handle.
If a low oil Driver Information Center
(DIC) message displays, check the oil
level.
Follow these guidelines:
. To get an accurate reading, park
the vehicle on level ground. Check
the engine oil level after the
engine has been off for at least
two hours. Checking the engine oil
level on steep grades or too soon
after engine shutoff can result in
incorrect readings. Accuracy
improves when checking a cold
engine prior to starting. Remove
the dipstick and check the level.
