PRINCIPLE OF OPERATION
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,
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.
Note: If your vehicle has MyKey ™, the
sensing system cannot be switched off
when a MyKey ™ is present.
See Principle
of Operation (page 64).
Note: Keep the sensors on the bumper or
fascia 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: If your vehicle sustains damage to
the bumper or fascia, leaving it misaligned
or bent, the sensing zone may be altered
causing inaccurate measurement of
obstacles or false alerts. 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 may block the normal detection zone
of the system. Remove the add-on device
to prevent false alerts.
Note: When you connect a trailer to your
vehicle, the rear parking aid may detect the
trailer and therefore provide an alert. Disable
the rear parking aid when you connect a
trailer to prevent the alert.
The sensing system warns the driver of
obstacles within a certain range of your
vehicle. The system turns on automatically
whenever you switch the ignition on.
You can switch the system off through the
touchscreen, information display or from
the pop-up message that appears once
you shift the transmission into reverse (R).
If your vehicle has a parking aid button, you
can switch the system off by pressing the
button.
If a fault is present in the system, a warning
message appears in the information
display. See Information Messages
(page 121).
REAR PARKING AID 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:
The system may not
detect small or moving objects,
particularly those close to the ground.

When you shift into neutral (N), the system
only provides visual indication if your
vehicle is moving at a speed of
approximately 5 mph (8 km/h) or below,
for example, your vehicle is moving on a
slope, and the system detects an object
moving toward your vehicle. When you
stop your vehicle, visual indication stops
after four seconds.
SIDE SENSING SYSTEM
(IF
EQUIPPED) 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:
The system may not
detect small or moving objects,
particularly those close to the ground. WARNING:
To help avoid personal
injury, always use caution when in

system. 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.
The system uses the front and rear
outermost parking aid sensors to detect
objects that are near to the sides of your
vehicle. The system displays them on a
virtual map in the information display as
your vehicle moves past them.
The sensors are on the front and rear
bumpers. Note:
Keep the sensors free from snow, ice
and large accumulations of dirt.
Note: Do not cover up the sensors.
Note: Do not clean the sensors with sharp
objects.

leaving the sensors misaligned, this may
cause inaccurate measurements or false
alerts.
The system may not function if:
• You switch the ignition 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.
Note: If you switch traction control off, the
side sensing system also turns off.
Note: Some accessories, for example large
trailer hitches or bike or surfboard racks can
cause reduced performance or false alerts.

of sensors not operating correctly, not enough room
for your vehicle, or the traction control is off.
The system does not correctly
operate.
You may have switched traction control off.
The system does not search for
a parking space.
The transmission is in reverse (R). Your vehicle must
be moving forward to be able to detect a parking space.
There could be blockage on the sensors. For example,
snow, ice or large accumulations of dirt. Blocked
sensors can affect how the system functions.
The system does not offer a
parking space.
The sensors in the front or rear bumper could be
damaged.
There is not enough room in the parking space for your
vehicle to safely park.

WARNING: Pay close attention to
changing road conditions such as
entering or leaving a highway, on roads
with intersections or roundabouts, roads
without visible lanes of travel, roads that
are winding, slippery, unpaved, or steep
slopes. WARNING:
The system does not
control speed in low traction conditions
or extremely steep slopes. 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
personal injury. WARNING:
The system is not a
crash warning or avoidance system. WARNING:
Do not use the system
when towing a trailer that has
aftermarket electronic trailer brake
controls. Failure to follow this instruction
could result in the loss of control of your
vehicle, personal injury or death. WARNING:
Do not use tire sizes
other than those recommended because
this can affect the normal operation of
the system. Failure to do so may result
in a loss of vehicle control, which could
result in serious injury. WARNING:
Do not use the system
with a snow plow blade installed. WARNING:
Do not use the system
in poor visibility, for example fog, heavy
rain, spray or snow. When Following a Vehicle WARNING:
When following a
vehicle that is braking, your vehicle does
not always decelerate quickly enough to
avoid a crash without driver intervention.
Apply the brakes when necessary. Failure
to follow this instruction could result in
personal injury or death.
Hilly Condition Usage
You should select a lower gear when the
system is active in situations such as
prolonged downhill driving on steep
grades, for example in mountainous areas.
The system needs additional engine
braking in these situations to reduce the
load on the vehicle ’s regular brake system
to prevent it from overheating.
Note: An audible alarm sounds and the
system shuts down if it applies brakes for
an extended period of time. This allows the
brakes to cool. The system functions
normally again after the brakes cool.
