PARKSENSE® FRONT AND REAR PARK ASSIST
— IF EQUIPPED
The ParkSense® Park Assist system provides visual and
audible indications of the distance between the rear
and/or front fascia and a detected obstacle when backing
up or moving forward, e.g. during a parking maneuver.
Refer to ParkSense® System Usage Precautions for limi-
tations of this system and recommendations.
ParkSense® will retain the last system state (enabled or
disabled) from the last ignition cycle when the ignition is
changed to the ON/RUN position.
ParkSense® can be active only when the shift lever is in
REVERSE or DRIVE. If ParkSense® is enabled at one of
these shift lever positions, the system will remain active
until the vehicle speed is increased to approximately
7 mph (11 km/h) or above. A display warning will
appear in the Driver Information Display (DID) indicat-
ing the vehicle is above ParkSense® operating speed. The
system will become active again if the vehicle speed is
decreased to speeds less than approximately 6 mph
(9 km/h).
ParkSense® Sensors
The four ParkSense® sensors, located in the rear fascia/
bumper, monitor the area behind the vehicle that is
within the sensors’ field of view. The sensors can detect
obstacles from approximately 12 in (30 cm) up to 79 in
(200 cm) from the rear fascia/bumper in the horizontal
direction, depending on the location, type and orienta-
tion of the obstacle.
The six ParkSense® sensors, located in the front fascia/
bumper, monitor the area in front of the vehicle that is
within the sensors’ field of view. The sensors can detect
obstacles from approximately 12 in (30 cm) up to 47 in
(120 cm) from the front fascia/bumper in the horizontal
direction, depending on the location, type and orienta-
tion of the obstacle.

Cleaning The ParkSense® System
Clean the ParkSense® sensors with water, car wash soap
and a soft cloth. Do not use rough or hard cloths. Do not
scratch or poke the sensors. Otherwise, you could dam-
age the sensors.
ParkSense® System Usage Precautions
NOTE:
•Ensure that the front and rear bumper are free of snow,
ice, mud, dirt and debris to keep the ParkSense®
system operating properly.
•Jackhammers, large trucks, and other vibrations could
affect the performance of ParkSense®.
•When you turn ParkSense® off, the instrument cluster
will display “PARKSENSE OFF.” Furthermore, once
you turn ParkSense® off, it remains off until you turn
it on again, even if you cycle the ignition key.
•When you move the shift lever to the REVERSE
position and ParkSense® is turned off, the instrument
cluster will display “PARKSENSE OFF” for as long as
the vehicle is in REVERSE.
•ParkSense®, when on, will reduce the volume of the
radio when it is sounding a tone.
•Clean the ParkSense® sensors regularly, taking care
not to scratch or damage them. The sensors must not
be covered with ice, snow, slush, mud, dirt or debris.
Failure to do so can result in the system not working
properly. The ParkSense® system might not detect an
obstacle behind or in front of the fascia/bumper, or it
could provide a false indication that an obstacle is
behind or in front of the fascia/bumper.
240 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

•Use the ParkSense® switch to turn the ParkSense®
system off if objects such as bicycle carriers, trailer
hitches, etc. are placed within 12 in (30 cm) from the
rear fascia/bumper. Failure to do so can result in the
system misinterpreting a close object as a sensor
problem, causing the “PARKSENSE UNAVAILABLE
SERVICE REQUIRED” message to be displayed in the
instrument cluster.
•ParkSense® should be disabled when the liftgate is in
the open position. An opened liftgate could provide a
false indication that an obstacle is behind the vehicle.
CAUTION!
•ParkSense® is only a parking aid and it is unable to
recognize every obstacle, including small obstacles.
Parking curbs might be temporarily detected or not
detected at all. Obstacles located above or below
the sensors will not be detected when they are in
close proximity.
•The vehicle must be driven slowly when using
ParkSense® in order to be able to stop in time
when an obstacle is detected. It is recommended
that the driver looks over his/her shoulder when
using ParkSense®.

WARNING!
•Drivers must be careful when backing up even
when using ParkSense®. Always check carefully
behind your vehicle, look behind you, and be sure
to check for pedestrians, animals, other vehicles,
obstructions, and blind spots before backing up.
You are responsible for safety and must continue to
pay attention to your surroundings. Failure to do so
can result in serious injury or death.
(Continued)
WARNING!(Continued)
•Before using ParkSense®, it is strongly recom-
mended that the ball mount and hitch ball assem-
bly is disconnected from the vehicle when the
vehicle is not used for towing. Failure to do so can
result in injury or damage to vehicles or obstacles
because the hitch ball will be much closer to the
obstacle than the rear fascia when the loudspeaker
sounds the continuous tone. Also, the sensors
could detect the ball mount and hitch ball assem-
bly, depending on its size and shape, giving a false
indication that an obstacle is behind the vehicle.
242 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is not
operating properly. The TPMS malfunction indicator is
combined with the low tire pressure telltale. When the
system detects a malfunction, the telltale will flash for
approximately one minute and then remain continuously
illuminated. This sequence will continue upon subse-
quent vehicle start-ups as long as the malfunction exists.
When the malfunction indicator is illuminated, the sys-
tem may not be able to detect or signal low tire pressure
as intended. TPMS malfunctions may occur for a variety
of reasons, including the installation of replacement or
alternate tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check the
TPMS malfunction telltale after replacing one or more
tires or wheels on your vehicle, to ensure that the
replacement or alternate tires and wheels allow the TPMS
to continue to function properly.
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system opera-
tion or sensor damage may result when using re-
placement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Do not use tire sealant from a can or
balance beads if your vehicle is equipped with a
TPMS, as damage to the sensors may result.
15. Driver Information Display (DID)
The odometer display shows the total distance the ve-
hicle has been driven.

setting had been selected. Press the back arrow button on
the touchscreen to return to the previous menu.
•Blind Spot Alert
When this feature is selected, the Blind Spot Alert feature
Provides alerts, visual and/or audible, to indicate objects
in your blind spot. The Blind Spot Alert feature can be
activated in “Lights” mode. When this mode is selected,
the Blind Spot Monitor (BSM) system is activated and
will only show a visual alert in the exterior mirrors.
When “Lights & Chime” mode is activated, the Blind
Spot Monitor (BSM) will show a visual alert in the
exterior mirrors as well as an audible alert when the turn
signal is on. When “Off” is selected, the Blind Spot
Monitor (BSM) system is deactivated. To change the
Blind Spot Alert status, press the “Off,” “Lights” or
“Lights & Chime” button on the touchscreen. Then press
the back arrow button on the touchscreen.
NOTE:If your vehicle has experienced any damage in
the area where the sensor is located, even if the fascia is
