STARTING AND OPERATING159
NOTE:
The system is designed to assist the driver and
not to substitute the driver.
The driver must stay in full control of the
vehicle's acceleration and braking, and is
responsible for the vehicle's movements.
For limitations of this system and
recommendations, see Ú page 163.
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 gear
selector is in REVERSE or DRIVE. If ParkSense is
enabled at one of these gear selector positions,
the system will remain active until the vehicle
speed is increased to approximately 7 mph
(11 km/h) or above. When in REVERSE and above
the system's operating speed, a warning will
appear in the instrument cluster display indicating
the vehicle speed is too fast. 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 six ParkSense sensors (four when vehicle is
not equipped with front sensors), located in the
rear fascia/bumper, and the six ParkSense
sensors located in the front fascia/bumper,
monitor the area in front and behind the vehicle
that is within the sensors’ field of view. The front
sensors detect obstacles from approximately
12 inches (30 cm) up to 47 inches (120 cm) from
the front fascia/bumper. The rear sensors can
detect obstacles from approximately 12 inches
(30 cm) up to 79 inches (200 cm) from the rear
fascia/bumper. These distances depend on the
location, type and orientation of the obstacle in the
horizontal direction.

Rear Sensor Locations

PARKSENSE DISPLAY
The warning display will turn on indicating the
system status when the vehicle is in REVERSE or
when the vehicle is in DRIVE and an obstacle has
been detected.
The system will indicate a detected obstacle by
showing a single arc in the left and/or right front or
rear regions based on the object’s distance and
location relative to the vehicle.
If an object is detected in the left and/or right rear
region, the display will show a single arc in the left
and/or right rear region and the system will
produce a tone. As the vehicle moves closer to the
object, the display will show the single arc moving
closer to the vehicle and the tone will change from
a single 1/2 second tone to slow, to fast, to
continuous.

STARTING AND OPERATING163
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
requires service, the ParkSense switch LED will
blink momentarily, and then the LED will be on.
NOTE:When KeySense feature is present, the ParkSense
system will reject customer input to turn the
system off via the switch. The instrument cluster
display will show "KeySense in Use Selected
Feature Cannot be Disabled" message.
SERVICE THE PARKSENSE PARK ASSIST
S
YSTEM
During vehicle start up, when the ParkSense
system has detected a faulted condition, the
instrument cluster will actuate a single chime,
once per ignition cycle, and it will display the
"PARKSENSE UNAVAILABLE WIPE REAR
SENSORS", "PARKSENSE UNAVAILABLE WIPE
FRONT SENSORS", or the "PARKSENSE
UNAVAILABLE SERVICE REQUIRED" message for
five seconds. When the gear selector is moved to
REVERSE and the system has detected a faulted
condition, the instrument cluster display will show
a "PARKSENSE UNAVAILABLE WIPE REAR
SENSORS", "PARKSENSE UNAVAILABLE WIPE
FRONT SENSORS" or "PARKSENSE UNAVAILABLE
SERVICE REQUIRED" pop-up message for five seconds. After five seconds, a vehicle graphic will
be displayed with a "WIPE OFF" or “SERVICE”
overlay, depending on the location and fault type.
The system will continue to provide arc alerts for
the side that is functioning properly. These arc
alerts will interrupt the "PARKSENSE UNAVAILABLE
WIPE REAR SENSORS", "PARKSENSE
UNAVAILABLE WIPE FRONT SENSORS", or
"PARKSENSE UNAVAILABLE SERVICE REQUIRED"
messages if an object is detected within the five
second pop-up duration. The vehicle graphic will
remain displayed for as long as the vehicle is in
REVERSE.
If "PARKSENSE UNAVAILABLE WIPE REAR
SENSORS" or "PARKSENSE UNAVAILABLE WIPE
FRONT SENSORS" appears in the instrument
cluster display make sure the outer surface and
the underside of the rear fascia/bumper and/or
front fascia/bumper is clean and clear of snow,
ice, mud, dirt or other obstruction and then cycle
the ignition. If the message continues to appear
see an authorized dealer.
If the "PARKSENSE UNAVAILABLE SERVICE
REQUIRED" message appears in the instrument
cluster display, see an authorized dealer.
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.
PARKSENSE SYSTEM USAGE
P
RECAUTIONS
NOTE:
Ensure that the front and rear fascia/bumper
are free of snow, ice, mud, dirt, and debris to
keep the ParkSense system operating properly.
Construction equipment, large trucks, and other
vibrations could affect the performance of Park-
Sense.
When you turn ParkSense off, the instrument
cluster will display “PARKSENSE OFF.” Further -
more, 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 gear selector to the
REVERSE position and ParkSense is turned off,
the instrument cluster will display “PARKSENSE
OFF” for five seconds while the vehicle is in
REVERSE.
4

21_RUP_OM_EN_USC_t.book Page 163

164STARTING AND OPERATING
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 appropriate fascia/
bumper, or it could provide a false indication
that an obstacle is behind or in front of the
appropriate 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 WIPE REAR
SENSORS” 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.
There may be a delay in the object detection
rate if the object is moving. This may cause the
automatic braking application to be delayed.
PARKSENSE ACTIVE PARK ASSIST
SYSTEM — IF EQUIPPED
The ParkSense Active Park Assist system is
intended to assist the driver during parallel and
perpendicular parking maneuvers by identifying a
proper parking space, providing audible/visual
instructions, and controlling the steering wheel.
The ParkSense Active Park Assist system is
defined as “semi-automatic” since the driver
maintains control of the accelerator, gear selector
and brakes.
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.
Before using ParkSense, it is strongly recom -
mended that the ball mount and hitch ball
assembly be 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 vehicle sounds the
continuous tone. Also, the sensors could
detect the ball mount and hitch ball assembly,
depending on its size and shape, giving 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 recom -
mended that the driver looks over his/her
shoulder when using ParkSense.

21_RUP_OM_EN_USC_t.book Page 164

STARTING AND OPERATING165
Depending on the driver's parking maneuver
selection, the ParkSense Active Park Assist system
is capable of maneuvering a vehicle into a parallel
or a perpendicular parking space on either side
(i.e., driver side or passenger side).
NOTE:
The driver is always responsible for controlling
the vehicle, responsible for any surrounding
objects, and must intervene as required.
The system is designed to assist the driver and
not to substitute the driver.
During a semi-automatic maneuver, if the driver
touches the steering wheel after being
instructed to remove their hands from the
steering wheel, the system will cancel, and the
driver will be required to manually complete the
parking maneuver.
The system may not work in all conditions (e.g.
environmental conditions such as heavy rain,
snow, etc., or if searching for a parking space
that has surfaces that will absorb the ultrasonic
sensor waves).
New vehicles from the dealership must have at
least 30 miles (48 km) accumulated before the
ParkSense Active Park Assist system is fully cali -
brated and performs accurately. This is due to
the system’s dynamic vehicle calibration to
improve the performance of the feature.
The use of wheels and tires that are different
size to the original equipment could affect the
operation of the system.
ENABLING AND DISABLING THE
P
ARKSENSE ACTIVE PARK ASSIST
S
YSTEM
The ParkSense Active Park Assist system can be
enabled and disabled with the ParkSense Active
Park Assist switch, located on the switch panel
below the Uconnect display.
To enable or disable the ParkSense
Active Park Assist system, push the
ParkSense Active Park Assist switch once
(LED turns on). Pushing the switch a
second time will disable the system (LED turns off).
The ParkSense Active Park Assist system will turn
off automatically for any of the following
conditions:
Parking maneuver is completed.
Vehicle speed is greater than 18 mph
(30 km/h) when searching for a parking space.
Vehicle speed is greater than 5 mph (7 km/h) during active steering guidance into the parking
space.
Steering wheel is touched during active steering
guidance into the parking space.
ParkSense switch is pushed.
The driver’s door is opened.
The liftgate is opened.
Electronic Stability Control/Anti-Lock Braking
System intervention.
The ParkSense Active Park Assist system will allow
a maximum of eight shifts between DRIVE and
REVERSE. If the maneuver cannot be completed
within eight shifts, the system will cancel and the
instrument cluster display will instruct the driver to
complete the maneuver manually.
The ParkSense Active Park Assist system will only
operate and search for a parking space when the
following conditions are present:
The gear selector is in DRIVE.
The ignition is in the RUN position.
The ParkSense Active Park Assist switch is
activated.
The driver’s door is closed.
The liftgate is closed.
Vehicle speed is less than 15 mph (25 km/h).
The outer surface and the underside of the front
and rear fascias/bumpers are clean and clear
of snow, ice, mud, dirt or other obstruction.
4

21_RUP_OM_EN_USC_t.book Page 165

168STARTING AND OPERATING
The system will cancel the maneuver if the
vehicle speed exceeds 5 mph (7 km/h) during
active steering guidance into the parking space.
The system will provide a warning to the driver
at 3 mph (5 km/h) that tells them to slow down.
The driver is then responsible for completing the
maneuver if the system is canceled.
If the system is canceled during the maneuver
for any reason, the driver must take control of
the vehicle.
LANESENSE — IF EQUIPPED
LANESENSE OPERATION
The LaneSense system is operational at speeds
above 37 mph (60 km/h) and below 112 mph
(180 km/h). It uses a forward looking camera to
detect lane markings and measure vehicle
position within the lane boundaries. When both lane markings are detected and the
driver drifts out of the lane (no turn signal applied),
the LaneSense system provides a haptic warning
in the form of torque applied to the steering wheel,
as well as a visual warning in the instrument
cluster display, to prompt the driver to remain
within the lane boundaries.
The driver may manually override the haptic
warning by applying force into the steering wheel at
any time.
When only a single lane marking is detected and
the driver unintentionally drifts across that lane
marking (no turn signal applied), the LaneSense
system provides a visual warning through the
instrument cluster display to prompt the driver to
remain within the lane. When only a single lane
marking is detected, a haptic or a torque warning
will not be provided.
NOTE:When operating conditions have been met, the
LaneSense system will monitor if the driver’s
hands are on the steering wheel and provide an
audible and visual warning to the driver when the
driver’s hands are not detected on the steering
wheel. The system will cancel if the driver does not
return their hands to the wheel.
WARNING!
Drivers must be careful when performing
parallel or perpendicular parking maneuvers
even when using the ParkSense Active Park
Assist system. Always check carefully behind
and in front of your vehicle, look behind and in
front of you, and be sure to check for
pedestrians, animals, other vehicles,
obstructions, and blind spots before backing up
and moving forward. 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.
CAUTION!
The ParkSense Active Park Assist system 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
the ParkSense Active Park Assist system 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 the ParkSense Active Park Assist
system.

21_RUP_OM_EN_USC_t.book Page 168

236SAFETY
NOTE:The DST feature is only meant to help the driver
realize the correct course of action through small
torques on the steering wheel, which means the
effectiveness of the DST feature is highly
dependent on the driver’s sensitivity and overall
reaction to the applied torque. It is very important
to realize that this feature will not steer the vehicle,
meaning the driver is still responsible for steering
the vehicle.
Electronic Brake Force Distribution (EBD)
The EBD function manages the distribution of the
braking torque between the front and rear axles by
limiting braking pressure to the rear axle. This is
done to prevent overslip of the rear wheels to avoid
vehicle instability, and to prevent the rear axle from
entering the Anti-Lock Brake System (ABS) before
the front axle.
Electronic Roll Mitigation (ERM)
ERM anticipates the potential for wheel lift by
monitoring the driver’s steering wheel input and
the speed of the vehicle. When ERM determines
that the rate of change of the steering wheel angle
and vehicle’s speed are sufficient to potentially
cause wheel lift, it then applies the appropriate
brake and may also reduce engine power to lessen
the chance that wheel lift will occur. ERM can only
reduce the chance of wheel lift occurring during
severe or evasive driving maneuvers; it cannot
prevent wheel lift due to other factors, such as
road conditions, leaving the roadway, striking
objects or other vehicles.
Electronic Stability Control (ESC)
ESC enhances directional control and stability of
the vehicle under various driving conditions. ESC
corrects for oversteering or understeering of the
vehicle by applying the brake of the appropriate
wheel(s) to assist in counteracting the above
conditions. Engine power may also be reduced to
help the vehicle maintain the desired path.
Oversteer — when the vehicle is turning more
than appropriate for the steering wheel position.
Understeer — when the vehicle is turning less
than appropriate for the steering wheel position.
ESC uses sensors in the vehicle to determine the
vehicle path intended by the driver and compares
it to the actual path of the vehicle. When the actual
path does not match the intended path, ESC
applies the brake of the appropriate wheel to
assist in counteracting the oversteer or understeer
condition.
WARNING!
Many factors, such as vehicle loading, road
conditions and driving conditions, influence the
chance that wheel lift or rollover may occur. ERM
cannot prevent all wheel lift or rollovers,
especially those that involve leaving the roadway
or striking objects or other vehicles. The
capabilities of an ERM-equipped vehicle must
never be exploited in a reckless or dangerous
manner which could jeopardize the user's safety
or the safety of others.

21_RUP_OM_EN_USC_t.book Page 236

240SAFETY
Trailer Sway Control (TSC)
TSC uses sensors in the vehicle to recognize an
excessively swaying trailer and will take the
appropriate actions to attempt to stop the sway.
Note that TSC cannot stop all trailers from swaying.
Always use caution when towing a trailer and follow
the trailer tongue weight recommendations
Úpage 177.
When TSC is functioning, the ESC Activation/
Malfunction Indicator Light will flash, the engine
power may be reduced and you may feel the
brakes being applied to individual wheels to
attempt to stop the trailer from swaying. TSC is
disabled when the ESC system is in the “Partial
Off” mode.AUXILIARY DRIVING SYSTEMS
BLIND SPOT MONITORING (BS M) —
I
F EQUIPPED
The BSM system uses two radar sensors, located
inside the rear fascia/bumper, to detect highway
licensable vehicles (automobiles, trucks,
motorcycles, etc.) that enter the blind spot zones
from the rear/front/side of the vehicle.

Rear Detection Zones

When the vehicle is started, the BSM Warning Light
will momentarily illuminate in both outside
rearview mirrors to let the driver know that the
system is operational. The BSM system sensors
operate when the vehicle is in any forward gear
and enters standby mode when the vehicle is in
PARK (P). The BSM detection zone covers approximately one
lane width on both sides of the vehicle 12 ft
(3.7 m). The zone length starts at the outside
rearview mirror and extends approximately 10 ft
(3 m) beyond the rear fascia/bumper of the
vehicle. The BSM system monitors the detection
zones on both sides of the vehicle when the vehicle
speed reaches approximately 6 mph (10 km/h) or
higher and will alert the driver of vehicles in these
areas.
NOTE:
The BSM system DOES NOT alert the driver
about rapidly approaching vehicles that are
outside the detection zones.
The BSM system detection zone DOES NOT
change if your vehicle is towing a trailer. There
-
fore, visually verify the adjacent lane is clear for
both your vehicle and trailer before making a
lane change. If the trailer or other object (i.e.,
bicycle, sports equipment) extends beyond the
side of your vehicle, this may result in false
detections. The BSM warning light may even
remain illuminated the entire time the vehicle is
in a forward gear.
The Blind Spot Monitoring (BSM) system may
experience drop outs (blinking on and off) of the
side mirror Warning Indicator lamps when a
motorcycle or any small object remains at the
side of the vehicle for extended periods of time
(more than a couple of seconds).
WARNING!
If TSC activates while driving, slow the vehicle
down, stop at the nearest safe location, and
adjust the trailer load to eliminate trailer sway.

21_RUP_OM_EN_USC_t.book Page 240

SAFETY241
The area on the rear fascia/bumper where the
radar sensors are located must remain free of
snow, ice, and dirt/road contamination so that the
BSM system can function properly. Do not block
the area of the rear fascia/bumper where the
radar sensors are located with foreign objects
(bumper stickers, bicycle racks, etc.).

Sensor Location

If the system detects degraded performance due
to contamination or foreign objects, a message will
warn you of a blocked sensor and the warning
indicators in side view mirrors will be on. The
warning indicators will remain illuminated until
blockage clearing conditions are met. First clear
the fascia/bumper area around the sensors of the
blockage. After removing the blockage, cycle the
ignition from on to off and then back on again to
reset the system. If the blockage message is still present after
cycling the ignition and driving in traffic, check
again for a blockage.
The BSM system notifies the driver of objects in the
detection zones by illuminating the BSM warning
light located in the outside mirrors in addition to
sounding an audible (chime) alert and reducing the
radio volume Ú
page 243.

Warning Light Location
The BSM system monitors the detection zone from
three different entry points (side, rear, front) while
driving to see if an alert is necessary. The BSM
system will issue an alert during these types of
zone entries.
Entering From The Side
Vehicles that move into your adjacent lanes from
either side of the vehicle.

Side Monitoring

21_RUP_OM_EN_USC_t.book Page 241

SAFETY243
Rear Cross Path (RCP)
RCP is intended to aid the driver when backing out
of parking spaces where their vision of oncoming
vehicles may be blocked. Proceed slowly and
cautiously out of the parking space until the rear
end of the vehicle is exposed. The RCP system will
then have a clear view of the cross traffic and if an
oncoming vehicle is detected, alert the driver.

RCP Detection Zones

RCP monitors the rear detection zones on both
sides of the vehicle, for objects that are moving
toward the side of the vehicle with a minimum
speed of approximately 3 mph (5 km/h), to objects
moving a maximum of approximately 20 mph
(32 km/h), such as in parking lot situations.
NOTE:In a parking lot situation, oncoming vehicles can be
blocked by vehicles parked on either side. If the
sensors are blocked by other structures or
vehicles, the system will not be able to alert the
driver. Additionally, if your vehicle is obscured by a
flat object on one side the system can false alert
on vehicles approaching from the opposite
direction.
When RCP is on and the vehicle is in REVERSE (R),
the driver is alerted using both the visual and
audible alarms, including reducing the radio
volume.Blind Spot Modes
Three selectable modes of operation are available
in the Uconnect system.
Blind Spot Alert Lights Only — Default Setting
When operating in Blind Spot Alert mode, the BSM
system will provide a visual alert in the appropriate
side view mirror based on a detected object.
However, when the system is operating in Rear
Cross Path (RCP) mode, the system will respond
with both visual and audible alerts when a
detected object is present. Whenever an audible
alert is requested, the radio is muted.
Blind Spot Alert Lights/Chime
When operating in Blind Spot Alert Lights/Chime
mode, the BSM system will provide a visual alert in
the appropriate side view mirror based on a
detected object. If the turn signal is then activated,
and it corresponds to an alert present on that side
of the vehicle, an audible chime will also be
sounded. Whenever a turn signal and detected
object are present on the same side at the same
time, both the visual and audible alerts will be
issued. In addition to the audible alert the radio (if
on) will also be muted.
NOTE:Whenever an audible alert is requested by the
BSM system, the radio is also muted.
WARNING!
Rear Cross Path Detection (RCP) is not a back up
aid system. It is intended to be used to help a
driver detect an oncoming vehicle in a parking
lot situation. Drivers must be careful when
backing up, even when using RCP. 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. Failure to do so can result in
serious injury or death.6

21_RUP_OM_EN_USC_t.book Page 243

244SAFETY
When the system is in RCP, the system shall
respond with both visual and audible alerts when a
detected object is present. Whenever an audible
alert is requested, the radio is also muted. Turn/
hazard signal status is ignored; the RCP state
always requests the chime.
Blind Spot Alert Off
When the BSM system is turned off there will be no
visual or audible alerts from either the BSM or RCP
systems.
NOTE:
The BSM system will store the current operating
mode when the vehicle is shut off. Each time the
vehicle is started the previously stored mode
will be recalled and used.
The BSM system can work in conjunction with
the KeySense function of the vehicle (if
equipped) Ú page 115.
FORWARD COLLISION WARNING (FCW)
W
ITH MITIGATION — IF EQUIPPED
FCW with Mitigation provides the driver with
audible warnings, visual warnings (within the
instrument cluster display), and may apply a brake
jerk to warn the driver when it detects a potential
frontal collision. The warnings and limited braking
are intended to provide the driver with enough time
to react, avoid or mitigate the potential collision.
NOTE:FCW monitors the information from the forward
looking sensors as well as the Electronic Brake
Controller (EBC), to calculate the probability of a
forward collision. When the system determines
that a forward collision is probable, the driver will
be provided with audible and visual warnings and
may provide a brake jerk warning.
If the driver does not take action based upon these
progressive warnings, then the system will provide
a limited level of active braking to help slow the
vehicle and mitigate the potential forward collision.
If the driver reacts to the warnings by braking and
the system determines that the driver intends to
avoid the collision by braking but has not applied
sufficient brake force, the system will compensate
and provide additional brake force as required.
If a FCW with Mitigation event begins at a speed
below 37 mph (60 km/h), the system may provide
the maximum braking possible to mitigate the
potential forward collision. If the Forward Collision
Warning with Mitigation event stops the vehicle
completely, the system will hold the vehicle at
standstill for two seconds and then release the
brakes. If a pedestrian is encountered in the path
at the same speed threshold, the system will
attempt to bring the vehicle to a stop.
FCW Message

When the system determines a collision with the
vehicle in front of you is no longer probable, the
warning message will be deactivated Úpage 387.
NOTE:
The minimum speed for FCW activation is
1 mph (2 km/h).
The FCW alerts may be triggered on objects
other than vehicles such as guard rails or sign
posts based on the course prediction. This is
expected and is a part of normal FCW activation
and functionality.
