rapidly beeps. 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). If the vehicle
has Adaptive Cruise Control (ACC), it can
detect vehicles to distances of approximately
110 m (360 ft) and operates at all speeds.
SeeAdaptive Cruise Control (Camera) 0256.
{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
0 206.
FCA can be disabled. See “Collision/Detection
Systems” underVehicle Personalization
0 137.
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,
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,

Warning (Continued)
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.

areas. The extended side blind zone area
adds the blind zone area along the side of a
trailer that the host vehicle is pulling.
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 that
extended blind zone. If the turn signal is
activated and a vehicle is also detected on
the same side, the display will flash as an
extra warning not to change lanes. Since
this system is part of the Lane Change Alert
system, read the entire Lane Change Alert
section before using this feature.
{Warning
ESBZA does not alert the driver to
vehicles outside of the system detection
zones, pedestrians, bicyclists, or animals.
It may not provide alerts when changing
lanes under all driving conditions. Failure
to use proper care when changing lanes
may result in injury, death, or vehicle
damage. Before making a lane change,
always check mirrors, glance over your
shoulder, and use the turn signals.ESBZA Detection Zones
1. SBZA Detection Zone
2. ESBZA Detection Zone
3. LCA Detection Zone
The Side Blind Zone Alert (SBZA) warning
area starts at approximately the middle of
the vehicle and goes back 5 m (16 ft). The
Extended Side Blind Zone Alert (ESBZA)
warning area starts at approximately 3 m
(10 ft) to the trailing edge of the vehicle and
goes back up to 21 m (69 ft) behind the
vehicle. The maximum trailer length is
12 m (39 ft).
How the System Works
The LCA/ESBZA symbol lights up in the side
mirrors when the system detects a moving
vehicle in the next lane over that is in the
extended side blind zone. This indicates it
may be unsafe to change lanes. Before making a lane change, check the SBZA
display, check mirrors, glance over your
shoulder, and use the turn signals.
Left Side Mirror
DisplayRight Side Mirror Display
When the vehicle is started, both outside
mirror LCA/ESBZA 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 that blind
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/ESBZA displays may not come on when
passing a vehicle quickly, or when passing a
stopped vehicle. LCA/ESBZA may alert to
objects attached to the vehicle, such as a
bicycle, or object extending out to either

pressure monitoring.
The trailer tire pressure sensors can transmit
up to 7 m (23 feet) from the hitch receiver of
the vehicle.
A trailer must be electrically connected to
the vehicle before starting the
sensor-to-vehicle learn process.
After selecting Start from the Learn Sensors
screen, use the Tool Method or the Manual
Method (described below) to learn each tire
sensor, during which the current tire number
will be highlighted.Each sensor has a maximum of two minutes
to learn. After a sensor is learned, a
checkmark appears next to the tire, the
vehicle horn sounds, the vehicle brake lamps
flash, and all working trailer lamps flash.
It then moves to the next sensor.
Touch Stop to cancel the process.
The recommended tire pressure must be
entered for the trailer tires. This allows the

pressure and temperature for each tire. To
set up, use one of the following options or
see a tire or trailer dealer for service. The
learning process must be repeated when the
trailer tires are rotated or replaced.
Tool Method: A TTPMS activation tool can
be purchased separately to learn the sensor
locations.
Manual Method: Without the tool, the air
pressure can be increased or decreased in
each tire for 10 seconds. Do not exceed the
maximum inflation pressure found on the
tire sidewalls. Make sure to readjust tire
pressure to the recommended level when

trailer lights may periodically flash as a
result of this trailer connection detection.
These flashes may be more visible in dark
ambient light environments. The flashing or
flickering lights are a normal condition and
the Trailering App System has built-in
protections to prevent the battery from
draining. When Theft Alert is enabled, the
frequency and pattern of this flashing will
change.
