Troubleshooting
The Transparent Trailer calibration
may take longer than expected or
not calibrate if:
. The vehicle is driven too fast
during calibration. Speed should
be maintained below 50 km/h
(31 mph).
. The vehicle is not driven straight
during calibration. Steering
should be maintained as straight
as possible, excessive steering
during calibration may extend
calibration time. .
The calibration is attempted in
low light. Calibration should be
attempted when there is enough
light.
. The calibration is attempted
during adverse weather
conditions. Calibration during
conditions such as snow or
heavy rain should be avoided.
. The road surface is not ideal for
calibration. Calibration should be
attempted on an alternate road
surface.
. The accessory trailer cameras
are swapped at the hitch
connector. Ensure that the
camera mounted to the rear of
the trailer is connected to the
rear trailer camera input.
. The accessory trailer camera is
mounted, angled or rotated
outside of the defined mounting
location (see camera installation
instructions).

With Front and Rear Park Assist, as
the vehicle moves at speeds of less
than 8 km/h (5 mph) the sensors on
the bumpers may detect objects up
to 1.2 m (4 ft) in front and 2.5 m (8 ft)
behind the vehicle within a zone
25 cm (10 in) high off the ground
and below bumper level. These
detection distances may be shorter
during warmer or humid weather.
Blocked sensors will not detect
objects and can also cause false
detections. Keep the sensors clean
of mud, dirt, snow, ice, and slush;
and clean sensors after a car wash
in freezing temperatures.
{Warning
The Park Assist system does not
detect children, pedestrians,
bicyclists, animals, or objects
located below the bumper or that
are too close or too far from the
vehicle. It is not available at
speeds greater than 8 km/h

Driving and Operating 267
Warning (Continued)
(5 mph). To prevent injury, death,
or vehicle damage, even with
Park Assist, always check the
area around the vehicle and
check all mirrors before moving
forward or backing.
The instrument cluster may have a
Park Assist display with bars that
show“distance to object” and object
location information for the Front
and Rear Park Assist system. As
the object gets closer, more bars
light up and the bars change color
from yellow to amber to red. When an object is first detected in
the rear, one beep will be heard
from the rear, or both sides of the
Safety Alert Seat will pulse two
times. When an object is very close
—
<0.4 m (1.5 ft) in the vehicle rear
or <0.3 m (1 ft) in the vehicle front —
a continuous beep will sound from
the rear or front depending on
object location, or both sides of the
Safety Alert Seat will pulse five
times. Beeps for FPA are higher
pitched than for RPA.
Rear Cross Traffic Alert (RCTA)
If equipped, when the vehicle is
shifted into R (Reverse), RCTA
shows a red warning triangle with a
left or right pointing arrow on the
infotainment display to warn of
traffic coming from the left or right.
This system detects objects coming
from up to 20 m (65 ft) from the left
or right side of the vehicle. When an
object is detected, either three
beeps sound from the left or right or
three Safety Alert Seat pulses occur
on the left or right side, depending
on the direction of the detected
vehicle. Use caution while backing up when
towing a trailer, as the RCTA
detection zones that extend out
from the back of the vehicle do not
move further back when a trailer is
towed.
RCTA is disabled when the trailer
connection status is displayed.
RCTA can be turned off. See
“Collision/Detection Systems”
under
Vehicle Personalization 0156.

Assistance Systems for
Driving
If equipped, when driving the
vehicle in a forward gear, Forward
Collision Alert (FCA), Lane
Departure Warning (LDW), Lane
Keep Assist (LKA), Side Blind Zone
Alert (SBZA), Lane Change Alert (LCA), Automatic Emergency
Braking (AEB), and/or the Front
Pedestrian Braking (FPB) System
can help to avoid a crash or reduce
crash damage.
Forward Collision Alert
(FCA) System
If equipped, the FCA system may
help to avoid or reduce the harm
caused by front-end crashes. When
approaching a vehicle ahead too
quickly, FCA provides a red flashing
alert on the windshield and rapidly
beeps or pulses the driver seat.
FCA also lights an amber visual
alert if following another vehicle
much too closely.
FCA detects vehicles within a
distance of approximately 60 m
(197 ft) and operates at speeds
above 8 km/h (5 mph).
{Warning
FCA is a warning system and
does not apply the brakes. When
approaching a slower-moving or
stopped vehicle ahead too rapidly,
or when following a vehicle too
closely, FCA may not provide a
warning with enough time to help
avoid a crash. It also may not
provide any warning at all. FCA
does not warn of pedestrians,
animals, signs, guardrails,
bridges, construction barrels,
or other objects. Be ready to take
action and apply the brakes. See
Defensive Driving
0187.
FCA can be disabled through
vehicle personalization. See
“Collision/Detection Systems” under
Vehicle Personalization 0156.

Driving and Operating 269
Detecting the Vehicle Ahead
FCA warnings will not occur unless
the FCA system detects a vehicle
ahead. When a vehicle is detected,
the vehicle ahead indicator will
display green. Vehicles may not be
detected on curves, highway exit
ramps, or hills, due to poor visibility;
or if a vehicle ahead is partially
blocked by pedestrians or other
objects. FCA will not detect another
vehicle ahead until it is completely
in the driving lane.
{Warning
FCA does not provide a warning
to help avoid a crash, unless it
detects a vehicle. FCA may not
detect a vehicle ahead if the FCA
sensor is blocked by dirt, snow,(Continued)
Warning (Continued)
or ice, or if the windshield is
damaged. It may also not detect a
vehicle on winding or hilly roads,
or in conditions that can limit
visibility such as fog, rain,
or snow, or if the headlamps or
windshield are not cleaned or in
proper condition. Keep the
windshield, headlamps, and FCA
sensors clean and in good repair.
Collision Alert
With Head-Up Display
Without Head-Up Display
When your vehicle approaches
another detected vehicle too rapidly,
the red FCA display will flash on the
windshield. Also, eight rapid
high-pitched beeps will sound from
the front, or both sides of the Safety
Alert Seat will pulse five times.
When this Collision Alert occurs, the
brake system may prepare for driver
braking to occur more rapidly which
can cause a brief, mild deceleration.
Continue to apply the brake pedal
as needed. Cruise control may be
disengaged when the Collision Alert
occurs.
