WHAT IS THE LANE KEEPING
SYSTEM
The lane keeping system alerts you by
providing temporary steering assistance
or steering wheel vibration when it detects
an unintended lane departure.
HOW DOES THE LANE
KEEPING SYSTEM WORK
The lane keeping system uses a forward
looking camera mounted on the windshield
to monitor vehicle movement within the
travel lane.
When the camera detects a drift out of the
travel lane, the lane keeping system alerts
the driver by vibrating the steering wheel,
or aids the driver by providing a small
steering input to move the vehicle back
into the travel lane.
The driver can select one of three modes:
•
Alert (If Equipped)
• Aid
• Alert + Aid
LANE KEEPING SYSTEM
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 will not
operate if the sensor cannot track the
road lane markings. WARNING:
The sensor may
incorrectly track lane markings as other
structures or objects. This can result in
a false or missed warning. WARNING:
In cold and severe
weather conditions the system may not
function. Rain, snow and spray can all
limit sensor performance. WARNING:
The system may not
operate properly if the sensor is blocked.
Keep the windshield free from
obstruction. WARNING:
If damage occurs in the
immediate area surrounding the sensor,
have your vehicle checked as soon as
possible. WARNING:
The system may not
correctly operate if your vehicle is fitted
with a suspension kit not approved by
us. WARNING:
Large contrasts in
outside lighting can limit sensor
performance.
LANE KEEPING SYSTEM
LIMITATIONS
The lane keeping system only operates
when the vehicle speed is greater than
40 mph (64 km/h)
.
The system works when the camera can
detect at least one lane marking.
Note: When you select Aid or Alert and Aid
mode and the system detects no steering
activity for a short period of time, the system
alerts you to put your hands on the steering
wheel. The system may detect a light grip
or touch on the steering wheel as hands-off
driving.

When you switch blind spot information
system off, a warning lamp illuminates and
a message displays. When you switch the
system on or off, the alert indicators flash
twice.
Note:
The system remembers the last
setting when you start your vehicle.
To permanently switch the system off,
contact an authorized dealer.
LOCATING THE BLIND SPOT
INFORMATION SYSTEM
SENSORS The sensors are inside the brake lamp on
both sides of your vehicle.
Note:
Keep the sensors free from snow, ice
and large accumulations of dirt.
Note: Do not cover the sensors with bumper
stickers, repair compound or other objects.
Note: Bike and cargo racks could cause
false alerts due to obstruction of the sensor.
We recommend switching the feature off
when using a bike or cargo rack.
Note: Blocked sensors may affect system
accuracy. If the sensors become blocked, a message
appears in the instrument cluster display.
See Blind Spot Information System –

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.

the following conditions:
•
You connect a trailer.
• The trailer is a bike rack or cargo rack
with a maximum length of 3 ft (1 m).
• You set the trailer length to
3 ft (1 m)
in the instrument cluster display.
Note: The system may not correctly operate
when towing a trailer. For vehicles with an
approved trailer tow module and tow bar,
the system turns off when you attach a
trailer. For vehicles with an aftermarket
trailer tow module or tow bar, we
recommend that you switch the system off
when you attach a trailer.

•
If required, switch the entire
pre-collision assist feature on or off.
• If required, switch evasive steering
assist on or off.
Note: Automatic emergency braking and
evasive steering turn on every time you
switch the ignition on.
Note: If your vehicle has a radar sensor, we
recommend that you switch the system off
if you install a snow plow or similar object
in such a way that it may block the radar
sensor. Your vehicle remembers the selected
setting across key cycles.
Note: If you switch automatic emergency
braking off, evasive steering assist switches
off.
LOCATING THE PRE-
COLLISION ASSIST SENSORS
- POLICE RESPONDER Camera.
1 If a message regarding a blocked camera
appears in the instrument cluster display,
something is obstructing the camera
images. With a blocked camera, the
system may not function, or performance
may reduce. See Pre-Collision Assist –
Information Messages (page 404).
Note: Proper system operation requires a
clear view of the road by the camera. Have
any windshield damage in the area of the
camera's field of view repaired.
Note: If your vehicle detects excessive heat
at the camera or a potential misalignment
condition, a message could display in the
information display indicating temporary
sensor unavailability. When operational
conditions are correct, the message
deactivates. For example, when the ambient
temperature around the sensor decreases
or the sensor recalibrates successfully.
