PARKING AID PRECAUTIONS
WARNING: To help avoid personal
injury, always use caution when in reverse
(R) and when using the sensing system. WARNING:
The system may not
detect objects with surfaces that absorb
reflection. Always drive with due care and
attention. Failure to take care may result
in a crash. WARNING:
Traffic control systems,
fluorescent lamps, inclement weather, air
brakes, external motors and fans may
affect the correct operation of the sensing
system. This may cause reduced
performance or false alerts. WARNING:
The system may not
detect small or moving objects, particularly
those close to the ground. WARNING:
The parking aid system
can only assist you to detect objects when
your vehicle is moving at parking speeds.
To help avoid personal injury you must
take care when using the parking aid
system. WARNING:
The system may not
function if the sensor is blocked. WARNING:
In cold and severe
weather conditions the system may not
function. Rain, snow and spray can all limit
sensor performance. WARNING:
If damage occurs in the
immediate area surrounding the sensor,
have your vehicle checked as soon as
possible.
Note: If your vehicle sustains damage
leaving the sensors misaligned, this will
cause inaccurate measurements or false
alerts. When you connect a trailer to your vehicle,
the rear parking aid detects the trailer and
provides an alert. Disable the parking aid
when you connect a trailer to prevent the
alert.
Note:
Certain add-on devices installed
around the bumper or fascia may create
false alerts, for example, large trailer hitches,
bike or surfboard racks, license plate
brackets, bumper covers or any other device
that could block the normal detection zone
of the parking aid system. Aftermarket spare
tires or spare tire covers mounted to the rear
tailgate could cause false alerts from the
park aid system. Remove the add-on device
to prevent false alerts.
Note: Keep the sensors free from snow, ice
and large accumulations of dirt. If the
sensors are covered, the system's accuracy
can be affected.
Do not clean the sensors with sharp objects.
Note: When using a programmed MyKey
you cannot switch this off.
See MyKey™
(page 84).

Note:
If the detected object is 12 in (30 cm)
or less from your vehicle, visual indication
remains on.
SIDE PARKING AID
What is the Side Parking Aid
The front and rear outermost parking aid
sensors map objects that are near to the
sides of your vehicle.
Side Parking Aid Limitations
The sensor coverage is up to
24 in (60 cm)
from the sides of your vehicle.
The side parking aid may not function if:
• You switch your vehicle on, off and back
on within a few seconds.
• Your vehicle remains stationary for over
two minutes.
• The anti-lock brake system activates.
• The traction control system activates. •
Your vehicle is in park (P).
• The steering wheel angle information is
not available. You must drive at least
492 ft (150 m) above 19 mph (30 km/h) to
reset the steering wheel angle
information.
Note: If you switch traction control off, the
side sensing system also turns off.
To reinitialize the system, drive the length of
your vehicle.
The side parking aid does not detect an
object that is moving toward the side of your
vehicle, for example another vehicle moving
at a low speed, if it does not pass a front or
rear parking aid sensor.
If the transmission is in reverse (R), the side
sensing system provides audible warnings.
When your vehicle is moving slowly,
obstacles are detected within
24 in (60 cm)
and are inside the driving path of your
vehicle. Once your vehicle reaches a
standstill condition, the audible warning
stops after a few seconds. Visual indication
is always present in reverse (R). If your vehicle is in neutral (N), the side
sensing system provides visual indication
only when your vehicle is moving slowly and
there is a front or rear park aid obstacle
detected, and the side obstacle is within
24 in (60 cm)
from the side of your vehicle.
Once your vehicle reaches a stop, the visual
indication stops after a few seconds.
If the transmission is in drive (D) or any other
forward gear, the side sensing system
provides audible and visual warnings. When
your vehicle is moving slowly, obstacles are
detected within
24 in (60 cm) and are inside
the driving path of your vehicle. Once your
vehicle reaches a standstill condition, the
audible warning and visual indication stops
after a few seconds.

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
L
ane-K eeping S ystem
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

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:
