SENSING SYSTEM (IF EQUIPPED)
WARNING:To help avoid personal injury, please read and
understand the limitations of the system as contained in this
section. Sensing is only an aid for some (generally large and fixed)
objects when moving in reverse on a flat surface at parking speeds.
Traffic control systems, inclement weather, air brakes, and external
motors and fans may also affect the function of the sensing system; this
may include reduced performance or a false activation.
WARNING:To help avoid personal injury, always use caution
when in R (Reverse) and when using the sensing system.
WARNING:This system is not designed to prevent contact with
small or moving objects. The system is designed to provide a
warning to assist the driver in detecting large stationary objects to avoid
damaging the vehicle. The system may not detect smaller objects,
particularly those close to the ground.
WARNING:Certain add-on devices such as large trailer hitches,
bike or surfboard racks and any device that may block the normal
detection zone of the system, may create false beeps.
Note:Keep the sensors (located on the bumper/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/fascia, leaving it
misaligned or bent, the sensing zone may be altered causing inaccurate
measurement of obstacles or false alarms.
The sensing system warns the driver of obstacles within a certain range
of the bumper area. The system turns on automatically whenever the
ignition is switched on.
When receiving a detection warning, the radio volume is reduced to a
predetermined level. After the warning goes away, the radio volume
returns to the previous level.

ACTIVE PARK ASSIST (IF EQUIPPED)
WARNING:This system is designed to be a supplementary park
aid. It may not work in all conditions and is not intended to
replace the driver’s attention and judgment. The driver is responsible
for avoiding hazards and maintaining a safe distance and speed, even
when the system is in use.
Note:The driver is always responsible for controlling the vehicle,
supervising the system and intervening if required.
The system detects an available parallel parking space and automatically
steers the vehicle into the space (hands-free) while you control the
accelerator, gearshift and brakes. The system visually and/or audibly
instructs the driver to park the vehicle.
The system may not function correctly if something passes between the
front bumper and the parking space (i.e. a pedestrian or cyclist) or if the
edge of the neighboring parked vehicle is high from the ground (i.e. a
bus, tow truck or flatbed truck).
Note:The sensors may not detect objects in heavy rain or other
conditions that cause disruptive reflections.
Note:The sensors may not detect objects with surfaces that absorb
ultrasonic waves.
The system should not be used if:
•a foreign object (i.e. bike rack or trailer) is attached to the front or
rear of the vehicle or at another location close to the sensors.
•an overhanging object (i.e. surfboard) is attached to the roof.
•the front bumper or side sensors are damaged (i.e. in a collision) or
obstructed by a foreign object (i.e. front bumper cover).
•a mini-spare tire is in use.

Deactivating the Park Assist Feature
The system can be deactivated manually by:
•pressing the active park assist button
•grabbing the steering wheel
•driving above approximately 20 mph (35 km/h) for 30 seconds during
an active park search
•driving above 6 mph (10 km/h) during automatic steering
•turning off the traction control system.
Certain vehicle conditions can also deactivate the system:
•Traction control has activated on a slippery or loose surface.
•Anti-lock brake system activation or failure.
•Any door (except the driver’s) opens.
•Something touches the steering wheel.
If a problem occurs with the system, a warning message is displayed,
followed by a chime. Occasional active park assist messages may occur in
normal operation. For recurring or frequent active park assist faults,
contact an authorized dealer to have your vehicle serviced.
Troubleshooting the System
The system does not look for a space
The traction control system may be off
Any door (except the driver’s) may not be completely closed
The system does not offer a particular space
Something may be contacting the front bumper or side sensors
There is not enough room on both sides of the vehicle in order to park
There is not enough space for the parking maneuver on the opposite
side of the parking space
The vehicle is farther than 5 ft (1.5 m) from the parking space
The vehicle is closer than 16 in. (40 cm) from neighboring parked
vehicles
The transmission is in R (Reverse); the vehicle must be moving forward
to detect a parking space

Setting Adaptive Cruise Control
1. Press and release ON.
The information display will show
the gray indicator light, current gap
setting and SET.
2. Accelerate to the desired speed.
3. Press SET upward and release. The vehicle speed will be stored in the
memory.
The information display will show a green indicator light,
current gap setting and desired set speed.
4. Take your foot off the accelerator pedal.
5. A lead vehicle graphic will

detected in front of you.
Following a Vehicle
WARNING:When following a vehicle in front of you, the vehicle
will not decelerate automatically to a stop, nor will the vehicle
always decelerate quickly enough to avoid a collision without driver
intervention. Always apply the brakes when necessary. Failing to do so
may result in a collision, serious injury or death.
WARNING:Adaptive cruise control only warns of vehicles
detected by the radar sensor. In some cases there may be no
warning or the warning may be delayed. The driver should always apply
the brakes when necessary. Failing to do so may result in a collision,
serious injury or death.
Note:The brakes may emit a sound when they are being modulated by
the adaptive cruise control system.

Detection Issues
The radar sensor has a limited field of vision. It may not detect vehicles at
all or detect a vehicle later than expected in some situations. The lead
vehicle graphic will not illuminate if a vehicle is not detected in front of you.
Detection issues can occur:
A. When driving on a different line
than the vehicle in front.
B. With vehicles that edge into your
lane. These vehicles can only be
detected once they have moved fully
into your lane.
C. There may be issues with the
detection of vehicles in front when
driving into and coming out of a
bend or curve in the road.
In these cases the system may brake late or unexpectedly. The driver
should stay alert and intervene when necessary.
If the front end of the vehicle is hit or damaged, the radar sensing zone may
be altered causing missed or false vehicle detections. See your authorized
dealer to have the radar checked for proper coverage and operation.
Adaptive Cruise Control Not Available
Several conditions exist which can cause the system to deactivate or
prevent the system from activating when requested. These conditions
include:
•a blocked sensor
•high brake temperature
•a failure in the system or a related system.

Blocked Sensor
WARNING:Do not use ACC when towing a trailer with brake
controls. Aftermarket trailer brakes will not function properly when
ACC is activated because the brakes are electronically controlled. Failing to
do so may result in loss of vehicle control, which could result in serious
injury.
WARNING:Do not use tires sizes other than those recommended
because this can affect the normal operation of ACC. Failing to do so
may result in a loss of vehicle control, which could result in serious injury.
A message regarding a blocked
sensor is displayed if the radar
signals from the sensor have been
obstructed. The sensor is located
behind a fascia cover near the driver
side of the lower grille. A vehicle
ahead cannot be detected and the
system will not function when the
radar signals are obstructed. The following table lists possible causes and
actions for this message being displayed.
Cause Action
The surface of the radar in the
grille is dirty or obstructed in
some wayClean the grille surface in front of
the radar or remove the object
causing the obstruction
The surface of the radar in the
grille is clean but the message
remains in the displayWait a short time. It may take
several minutes for the radar to
detect that it is no longer
obstructed
Heavy rain or snow is interfering
with the radar signalsDo not use ACC in these condition
because it may not detect, warn,
or respond to potential collisions.
Swirling water, or snow or ice on
the surface of the road may
interfere with the radar signalsDo not use ACC in these condition
because it may not detect, warn,
or respond to potential collisions.
