WHAT IS BLIND SPOT
INFORMATION SYSTEM
Blind spot information system detects
vehicles that may have entered the blind
spot zone.
HOW DOES BLIND SPOT
INFORMATION SYSTEM WORK
Blind spot information system uses
sensors on both sides of your vehicle,
detecting rearward from the exterior
mirrors to approximately 13 ft (4 m)
beyond the rear bumper. The detection
area extends to approximately 59 ft (18 m)
beyond the rear bumper when the vehicle
speed is greater than
30 mph (48 km/h)
to alert you of faster approaching vehicles. BLIND SPOT INFORMATION

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.

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.

WHAT IS CROSS TRAFFIC
ALERT
The system alerts you of vehicles
approaching from the sides behind your
vehicle when you shift into reverse (R).
HOW DOES CROSS TRAFFIC
ALERT WORK
Cross traffic alert detects vehicles that
approach at a speed between 4–
37 mph
(6–60 km/h). Coverage decreases when
the sensors are partially, mostly or fully
obstructed. The sensor on the left-hand side is only
partially obstructed and zone coverage on
the right-hand side is maximized.
Zone coverage also decreases when
parking at narrow angles. The sensor on
the left-hand side is mostly obstructed and
zone coverage on that side is severely
reduced.
Note:
Slowly reversing helps increase the
coverage area and effectiveness. CROSS TRAFFIC ALERT
PRECAUTIONS WARNING:
Do not use the cross
traffic alert system as a replacement for
using the interior and exterior mirrors or
looking over your shoulder before
reversing out of a parking space. The
cross traffic alert system is not a
replacement for careful driving. WARNING:
The system may not
operate properly during severe weather
conditions, for example snow, ice, heavy
rain and spray. Always drive with due
care and attention. Failure to take care
may result in a crash.
CROSS TRAFFIC ALERT
LIMITATIONS
The system may not correctly operate
when any of the following occur:
• Something is blocking the sensors.
• Adjacently parked vehicles or objects
are obstructing the sensors.
• Vehicles approach at speeds less than
4 mph (6 km/h) or greater than 37 mph
(60 km/h)
.
• Your vehicle speed is greater than
7 mph (12 km/h)
.
• You reverse out of an angled parking
space.

WHAT IS PRE-COLLISION
ASSIST
Pre-collision assist detects and warns of
approaching hazards in the roadway. If
your vehicle is rapidly approaching another
stationary vehicle, a vehicle traveling in the
same direction as yours, or a pedestrian
within your driving path, the system
provides multiple levels of assistance to
help avoid a collision.
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 397).
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 that are driving in a
different direction, cyclists 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.
