12460273) - 2019 - CRC - 5/16/18
240 DRIVING AND OPERATING
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" underExterior Care0335.
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.
Radio Frequency Information
See
Radio Frequency Statement 0373.
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
Keep Assist (LKA) system, read the
entire LKA section before using this
feature.
Lane Keep Assist (LKA)
If equipped, LKA may help avoid
crashes due to unintentional lane
departures. It may assist by gently
turning the steering wheel if the
vehicle approaches a detected lane
marking without using a turn signal in
that direction. It may also provide a
Lane Departure Warning (LDW)
system alert as the lane marking is
crossed. The LKA system will not
assist or provide an LDW alert if it
detects that you are actively steering.
Override LKA by turning the steering
wheel. LKA uses a camera to detect
lane markings between 60 km/h (37
mph) and 180 km/h (112 mph).
{Warning
The LKA system does not
continuously steer the vehicle.
It may not keep the vehicle in the
lane or give a Lane Departure
Warning (LDW) alert, even if a lane
marking is detected.

DRIVING AND OPERATING 241
Warning (Continued)
The LKA and LDW systems
may not:. Provide an alert or enough
steering assist to avoid a lane
departure or crash.
. Detect lane markings under
poor weather or visibility
conditions. This can occur if
the windshield or headlamps
are blocked by dirt, snow,
or ice, if they are not in
proper condition, or if the sun
shines directly into the
camera.
. Detect road edges.
. Detect lanes on winding or
hilly roads.
If LKA only detects lane markings
on one side of the road, it will only
assist or provide an LDW alert
when approaching the lane on the
side where it has detected a lane
marking. Even with LKA and LDW, (Continued)
Warning (Continued)
you must steer the vehicle. Always
keep your attention on the road and
maintain proper vehicle position
within the lane, or vehicle damage,
injury, or death could occur. Always
keep the windshield, headlamps,
and camera sensors clean and in
good repair. Do not use LKA in bad
weather conditions.
{Warning
Using LKA while towing a trailer or
on slippery roads could cause loss
of control of the vehicle and a
crash. Turn the system off.
How the System Works
The LKA camera sensor is on the
windshield ahead of the rearview
mirror.
To turn LKA on and off, press
A
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.

Cadillac CTS/CTS-V Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
12460273) - 2019 - CRC - 5/16/18
242 DRIVING AND OPERATING
.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 traveling 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.
V2V does not automatically brake or
steer the vehicle.
{Warning
V2V features work only when other
nearby vehicles equipped with V2V
are detected and communications
(Continued)
Warning (Continued)
are received. V2V may not detect
other V2V-equipped vehicles or
receive communications under
certain conditions, including
around tall buildings; in parking
garages; around airports; in tunnels
and underpasses; in an area with
very dense trees; or where the roof
antenna is blocked by objects such
as roof carriers, snow or ice.
Communication failures or delays
can occur and may not provide
notice sufficiently in advance to
help avoid a crash, or may not
provide any notices at all. Pay
attention to the road and operation
of the vehicle at all times and be
ready to take action and apply the
brakes. SeeDefensive Driving 0179.

{Warning
V2V does not detect or warn of
pedestrians, animals, signs,
guardrails, bridges, construction
barrels, or other objects.
Under certain conditions, V2V can
notify of situations that are beyond
line-of-sight. It is important to
understand the feature operation to be
prepared when events that may not be
seen immediately are detected.
Even if the V2V features are turned off
through vehicle personalization,
information from the vehicle is sent to
other vehicles equipped with V2V.
Other vehicles equipped with V2V may
be alerted to certain events involving
your vehicle, such as hard braking;
activation of hazard warning flashers;
an airbag deployment; or a
StabiliTrak/Electronic Stability Control
(ESC), Traction Control, or Antilock
Brake System (ABS) event. V2V
communications are not stored by the vehicle and cannot be used to identify
owners or occupants or to later track
the vehicle’s location.
Unnecessary Alerts
V2V features may provide alerts to
driving situations that are too early or
unnecessary. These alerts are normal
operation and the vehicle does not
need service.
SERVICE VEHICLE SOON
If this message displays, V2V features
may need service. Do not use them.
Take the vehicle to your dealer.
V2V Hard Braking Ahead
When the vehicle is traveling above
40 km/h (25 mph), V2V may detect
when a V2V-equipped vehicle ahead is
braking hard. Under these conditions,
V2V may display a Driver Information
Center (DIC) message and icon.
If equipped, a red flashing alert on the
windshield may also occur.

Recommended Fuel (LGX
3.6L V6 Engine)
Do not use any fuel labeled E85 or
FlexFuel. Do not use gasoline with
ethanol levels greater than 15% by
volume.
Use regular unleaded gasoline meeting
ASTM specification D4814 with a
posted octane rating of 87 or higher.
Do not use gasoline with a posted
octane rating of less than 87, as this
may cause engine knock and will
lower fuel economy.
Recommended Fuel (LTG
2.0L L4 Engine)
Do not use any fuel labeled E85 or
FlexFuel. Do not use gasoline with
ethanol levels greater than 15% by
volume.
Premium unleaded gasoline meeting
ASTM specification D4814 with a
posted octane rating of 93 is highly
recommended for best performance
and fuel economy. Unleaded gasoline
with an octane rated as low as 87 can
be used. Using unleaded gasolinerated below 93 octane, however, will
lead to reduced acceleration and fuel
economy. If knocking occurs, use a
gasoline rated at 93 octane as soon as
possible, otherwise, the engine could
be damaged. If heavy knocking is
heard when using gasoline with a
93 octane rating, the engine needs
service.
Recommended Fuel
(LF3 3.6L V6 Twin Turbo
and LT4 6.2L V8 Engines)
Do not use any fuel labeled E85 or
FlexFuel. Do not use gasoline with
ethanol levels greater than 15% by
volume.
Use premium unleaded gasoline
meeting ASTM specification D4814
with a posted octane rating of 93.
If unavailable, unleaded gasoline with
a posted octane rating of 91 may be
used, but with reduced performance
and fuel economy. If the octane is less
than 91, the engine could be damaged
and the repairs would not be covered
by the vehicle warranty. If heavy
knocking is heard when using gasoline
rated at 93 octane, the engine needs
service.
Prohibited Fuels
Caution
Do not use fuels with any of the
following conditions; doing so may
damage the vehicle and void its
