Cadillac XTS Owner Manual (GMNA-Localizing-U.S./Canada-12032610) -
2019 - CRC - 3/26/18
DRIVING AND OPERATING 223
When LDW is on, @ is green if LDW
is available to warn of a lane
departure. If the vehicle crosses a
detected lane marking without using
the turn signal in that direction,
@
changes to amber and flashes.
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.
When the System Does Not
Seem to Work Properly
The system may not detect lanes as
well when there are:
.
Close vehicles ahead.
.
Sudden lighting changes, such as
when driving through tunnels.
.
Banked roads.
If the LDW system is not functioning
properly when lane markings are
clearly visible, cleaning the windshield
may help.
LDW alert s 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 ser vice. Turn
LDW off if these conditions continue.
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.
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.
