(Continued)
Refer to the Starting And Operating section
in the Owner’s Manual.
Auto Park Brake
The electric park brake can be programmed
to be applied automatically whenever the
vehicle is at a standstill and the automatic
transmission is placed in PARK, or with a
manual transmission, whenever the ignition
is turned “OFF”. Auto Park Brake is enabled
and disabled by customer selection through
the Customer Programmable Features
section of the Uconnect Settings.
Any single auto park brake application can
be bypassed by pushing the EPB switch to
the release position while the transmission is
placed in PARK.
WARNING!
Never use the PARK position as a substi-
tute for the parking brake. Always apply
the parking brake fully when exiting the
vehicle to guard against vehicle move-
ment and possible injury or damage.
When exiting the vehicle, always make
sure the ignition is in the OFF mode,
remove the key fob from the vehicle, and
lock your vehicle.
Never leave children alone in a vehicle,
or with access to an unlocked vehicle.
Allowing children to be in a vehicle unat -
tended is dangerous for a number of
reasons. A child or others could be seri -
ously or fatally injured. Children should
be warned not to touch the parking
brake, brake pedal or the transmission
gear selector.
Do not leave the key fob in or near the
vehicle, (or in a location accessible to
children), and do not leave the ignition
in the ACC or ON/RUN mode. A child
could operate power windows, other
controls, or move the vehicle.
Be sure the parking brake is fully disen -
gaged before driving; failure to do so can
lead to brake failure and a collision.
Always fully apply the parking brake
when leaving your vehicle, or it may roll
and cause damage or injury. Also be
certain to leave the transmission in
PARK. Failure to do so may allow the
vehicle to roll and cause damage or
injury.

Driving the vehicle with the parking brake
engaged, or repeated use of the parking
brake to slow the vehicle may cause
serious damage to the brake system.

WARNING! (Continued) CAUTION!
If the Brake System Warning Light remains
on with the parking brake released, a
brake system malfunction is indicated.
Have the brake system serviced by an
authorized dealer immediately.

Enabling And Disabling ParkSense
ParkSense can be enabled and disabled with
the ParkSense switch located below the
Uconnect display.When the ParkSense switch is
pushed to disable the system, the
instrument cluster will display the
“PARKSENSE OFF” message for
approximately five seconds. When the gear
selector is moved to REVERSE and the
system is disabled, the instrument cluster
display will display the “PARKSENSE OFF”
message for as long as the vehicle is in
REVERSE.
Refer to “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel” in
your Owner’s Manual for further information.
The ParkSense switch LED will be on when
ParkSense is disabled or requires service.
The ParkSense switch LED will be off when
the system is enabled. If the ParkSense
switch is pushed, and the system requires
service, the ParkSense switch LED will blink
momentarily, and then the LED will be on.
ParkSense System Usage Precautions
NOTE:
Ensure that the rear bumper is 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 instru -
ment cluster will display “PARKSENSE
OFF.” Furthermore, once you turn Park-
Sense off, it remains off until you turn it
on again, even if you cycle the ignition.
When you move the gear selector to the
REVERSE position and ParkSense is
turned off, the instrument cluster display
will display “PARKSENSE OFF” message
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 the fascia/
bumper, or it could provide a false indica-
tion that an obstacle is behind the fascia/
bumper.
Use the ParkSense switch to turn the
ParkSense system off if objects such as
bicycle carriers, trailer hitches, etc. are
placed within 12 inches (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
display.
ParkSense should be disabled when the
liftgate is in the open position and the
vehicle is in REVERSE. An open liftgate
could provide a false indication that an
obstacle is behind the vehicle.

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 inches (30 cm) up to
79 inches (200 cm) from the rear fascia/
bumper in the horizontal direction,
depending on the location, type and orienta-
tion of the obstacle.
NOTE:
Vehicles equipped with Active Park Assist
will have six sensors in the rear fascia/
bumper.
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 obsta -
cles from approximately 12 inches (30 cm)
up to 47 inches (120 cm) from the front
fascia/bumper in the horizontal direction,
depending on the location, type and orienta -
tion of the obstacle. When an object is detected within 79 inches
(200 cm) behind the rear bumper while the
vehicle is in REVERSE, a warning will appear
in the instrument cluster display. In addition
a chime will sound (when Sound and Display
is selected from the Customer Programmable
Features section of the Uconnect System
screen). As the vehicle moves closer to the
object, the chime rate will change from
single 1/2 second tone (for rear only), to slow
(for rear only), to fast, to continuous.
Enabling And Disabling ParkSense
ParkSense can be enabled and disabled with
the ParkSense switch located below the
Uconnect display.
When the ParkSense switch is
pushed to disable the system, the
instrument cluster will display the
“PARKSENSE OFF” message for
approximately five seconds. When the gear
selector is moved to REVERSE and the
system is disabled, the instrument cluster
display will display the “PARKSENSE OFF”
message for as long as the vehicle is in
REVERSE. Refer to “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel” in
the Owner’s Manual for further information.
NOTE:
When ParkSense is disabled and the gear
selector is moved to the DRIVE position, no
warning message will be displayed.
The ParkSense switch LED will be on when
ParkSense is disabled or requires service.
The ParkSense switch LED will be off when
the system is enabled. If the ParkSense
switch is pushed, and the system requires
service, the ParkSense switch LED will blink
momentarily, and then the LED will be on.
