BLIND SPOT INFORMATION SYSTEM
WITH TRAILER COVERAGE
WHAT IS BLIND SPOT INFORMATION
SYSTEM WITH TRAILER COVERAGE
Blind spot information system detects
vehicles that may have entered the blind
spot zone. The detection area is on both
sides your vehicle and trailer, extending
rearward from the exterior mirrors to the end
of your trailer. BLIND SPOT INFORMATION SYSTEM
WITH TRAILER COVERAGE
LIMITATIONS
Trailer coverage only supports conventional
trailers. The system turns off if you select a
fifth wheel trailer type.
Make sure the trailer width is less than or
equal to 8.5 ft (2.6 m) and the length is less
than 33 ft (10.1 m). If you input values higher,
the system turns off.
Some trailers could cause a slight change in
system performance:
• Large box trailers could cause false alerts
to occur when driving next to
infrastructures or near parked cars. A
false alert could also occur while making
a 90-degree turn.
• Trailers that have a width greater than
8.5 ft (2.6 m)
at the front and have a total
length greater than 20 ft (6 m) could
cause delayed alerts when a vehicle is
passing at high speeds. •
Box trailers that have a width greater than
8.5 ft (2.6 m)
at the front could cause
early alerts when you pass a vehicle.
• Clam shell or v-nose box trailers with a
width greater than
8.5 ft (2.6 m) at the
front could cause delayed alerts when a
vehicle traveling the same speed as your
vehicle merges lanes.

You can set-up a trailer to work with the blind
spot information system through the
touchscreen. When setting up a trailer, a
sequence of screens appear asking for trailer
information.
1. Select type of trailer screen -
conventional, fifth wheel or gooseneck.
Note: The system only supports conventional
trailers.
2. Do you want to set up blind spot with trailer screen? If no, the system turns off.
If yes, the menu goes to the next screen.
3. Is the width less than 9 ft (2.7 m) and
length less than 33 ft (10.1 m)? If no, the
system turns off. If yes, the menu goes
to the next screen.
4. Trailer width measurement. Measure the
width at the front of the trailer. It is not
measured at the widest point of the
trailer. The maximum width at the front
of the trailer the system can support is
8.5 ft (2.6 m)
. Note:
You do not need to enter an exact
trailer width measurement. You only need
to confirm that the width of the trailer is less
than
9 ft (2.7 m).
5. Trailer length measurement. The trailer length is the distance between the trailer
hitch ball and the rear of the trailer. The
maximum length that the system can
support is
33 ft (10.1 m).
6. Enter the length of trailer. The default setting is
18 ft (5.5 m). Toggling up or
down using the menu buttons increases
or decreases the measurement by
3 ft
(1 m). Select a length that is equal to or
within 3 ft (1 m) of the actual measured
length. For example, if the actual
measure length is
25 ft (7.5 m), toggle
the length in the menu to 27 ft (8.2 m).
The system setup saves when you enter
the length of the trailer.
Note: If the trailer is a bike rack or cargo
rack with electrical lighting, enter a length
of 3 ft (1 m). Cross traffic alert remains on for
trailers with a length of
3 ft (1 m) or less. Note:
The system requires proper
measurement and measure entry to function
properly.
SELECTING A TRAILER
When you connect a trailer to your vehicle,
the trailer set up menu appears in the
touchscreen. This menu allows you to set up
a new trailer or choose from a previously set
up trailer. A warning message appears and
the system turns off if you do not choose or
add a new trailer.
Note: The warning message may not appear
until your vehicle reaches 22 mph (35 km/h).

WHAT IS PRE-COLLISION ASSIST
Pre-collision assist detects and warns of
approaching hazards in the roadway. The
system provides multiple levels of assistance
to help avoid a collision if your vehicle is
rapidly approaching another stationary
vehicle, a vehicle traveling in the same
direction as yours, or a pedestrian or cyclist
within your driving path.
HOW DOES PRE-COLLISION
ASSIST WORK
The system warns the driver of potential
hazards by providing three levels of
assistance.
If your vehicle is rapidly approaching
potential hazards the system provides the
following levels of functionality:
1. Alert.
2. Brake Support. 3. Automatic Emergency Braking. Alert: When active, a flashing
visual warning appears and an
audible warning tone sounds.
Brake Support
: The system is designed to
help reduce the impact speed by preparing
the brakes for rapid braking. The system
does not automatically apply the brakes. If
you press the brake pedal, the system could
apply additional braking up to maximum
braking force, even if you lightly press the
brake pedal.
Automatic Emergency Braking
: Automatic
emergency braking may activate if the
system determines that a collision is
imminent.
Note: If you perceive pre-collision assist
alerts as being too frequent or disturbing,
then you can reduce the alert sensitivity,
although the manufacturer recommends
using the highest sensitivity setting where
possible. Setting lower sensitivity would lead
to fewer and later system warnings.
Each system has various levels of detection
capabilities.
See Pre-Collision Assist
Limitations (page 321). PRE-COLLISION ASSIST
PRECAUTIONS WARNING:
You are responsible for
controlling your vehicle at all times. The
system is designed to be an aid and does
not relieve you of your responsibility to
drive with due care and attention. Failure
to follow this instruction could result in the
loss of control of your vehicle, personal
injury or death. WARNING:
The system does not
detect vehicles moving in a different
direction or animals. Apply the brakes
when necessary. Failure to follow this
instruction could result in the loss of
control of your vehicle, personal injury or
death. WARNING:
The system does not
operate during hard acceleration or
steering. Failure to take care may lead to
a crash or personal injury.

WARNING: The system may fail or
operate with reduced function during cold
and severe weather conditions. Snow, ice,
rain, spray and fog can adversely affect the
system. Keep the front camera and radar
free of snow and ice. Failure to take care
may result in the loss of control of your
vehicle, serious personal injury or death. WARNING:
Take additional care if
your vehicle is heavily loaded or you are
towing a trailer. These conditions could
result in reduced performance of this
system. Failure to follow this instruction
could result in the loss of control of your
vehicle, personal injury or death. WARNING:
The system cannot help
prevent all crashes. Do not rely on this
system to replace driver judgment and the
need to maintain a safe distance and
speed. WARNING:
In situations where the
vehicle camera has limited detection
capability, this may reduce system
performance. These situations include but
are not limited to direct or low sunlight,
vehicles at night without tail lights,
unconventional vehicle types, pedestrians
with complex backgrounds, running
pedestrians, partly obscured pedestrians,
or pedestrians that the system cannot
distinguish from a group. Failure to take
care may result in the loss of control of
your vehicle, serious personal injury or
death.
PRE-COLLISION ASSIST
LIMITATIONS
Pre-collision assist depends on the detection
ability of its camera and sensors. Any
obstructions or damage to these areas can
limit detection or prevent the system from
functioning.
See Locating the Pre-Collision
Assist Sensors (page 323). The system is active at speeds above 3 mph
(5 km/h)
.
Note: The pre-collision assist system
automatically disables when you select
four-wheel drive low or manually disable
AdvanceTrac ™.
Note: Brake support and automatic
emergency braking are active at speeds up
to
80 mph (130 km/h). If your vehicle has a
radar sensor included with adaptive cruise
control, then brake support and automatic
emergency braking are active up to the
maximum speed of your vehicle.
Pedestrian Detection Limitations
Pedestrian detection is active at speeds up
to
50 mph (80 km/h).
Pedestrian detection operates optimally
when detected hazards are clearly
identifiable. System performance may reduce
in situations where pedestrians are running,
partly obscured, have a complex
background, or cannot be distinguished from
a group.

Trailer Light Check
WARNING: Never connect any trailer
lamp wiring to the vehicle's tail lamp wiring;
this may damage the electrical system
resulting in fire. Contact your authorized
dealer as soon as possible for assistance
in proper trailer tow wiring installation.
Additional electrical equipment may be
required.
Most towed vehicles require trailer lamps.
Make sure all running lights, brake lights, turn
signals and hazard lights are working. Safety Chains
Install trailer safety chains to the trailer hitch
as recommended by the manufacturer. Cross
the chains under the trailer coupler and allow
enough slack for turning tight corners. Do
not allow the chains to drag on the ground.
Note:
Do not attach safety chains to the
bumper. Always connect the safety chains
to the frame or hook retainers of your trailer
hitch. If the trailer safety chain hook has a latch,
make sure to fully close the latch.
