Driving and Operating 205
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 indicator 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
personalisation. To view available settings
from the infotainment screen, touch Settings
> Vehicle > Collision/Detection Systems.
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 motorway 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
overtaking a vehicle quickly or for a stopped
vehicle. LCA may alert to objects attached to
the vehicle, such as a 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 Care 0 280. 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 Cadillac Service Centre.
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 Cadillac
Service Centre.
Driving with a Trailer
If equipped with Lane Change Alert (LCA),
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.
Side Bicycle Detection
If equipped, the system may detect a
bicyclist approaching from the side or rear
of the vehicle.
If this occurs, a chime will sound in the
direction of the detection, and the Safety
Alert Seat will pulse if enabled through
vehicle settings. To view available settings
from the infotainment screen, touch Settings
> Vehicle > Collision/Detection Systems.
Bicyclist Detection is available when the
vehicle is in D (Drive), P (Park), and for a
short time after the vehicle is turned off.
If the vehicle detects a bicyclist when it is
off, a DIC message may display and alert to
the direction of the detection. In some
