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 outside
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 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. When you disable LCA,
Side Blind Zone Alert is also disabled. 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.
If LCA is disabled by the driver, the LCA mirror
displays will not light up.
When the System Does Not Seem to
W
ork 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 driving on astraight highway
road with traffic and roadside objects (e.g.,
guardrails, barriers).
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
t
he 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
3244. 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 are rapidly
approaching this zone and the system is clean,
the system may need service. Take the vehicle
to your dealer.
