to depress the brake pedal or accelerator pedal, the park
brake will automatically engage to prevent the vehicle
from rolling.
SafeHold can be temporarily bypassed by pushing the
Electric Park Brake Switch while the driver door is open
and brake pedal is pressed. Once manually bypassed,
SafeHold will be enabled again once the vehicle reaches
12 mph (20 km/h) or the ignition is cycled to the OFF
position and back to ON again.
Brake Service Mode
We recommend having your brakes serviced by your
authorized dealer. You should only make repairs for which
you have the knowledge and the right equipment. You
should only enter Brake Service Mode during brake ser-
vice.
When servicing your rear brakes, it may be necessary for
you or your technician to push the rear piston into the rear
caliper bore. With the Electric Park Brake system, this can
only be done after retracting the Electric Park Brake
actuator. Fortunately, actuator retraction can be done easily
by entering the “Brake Service” through the “Uconnect
Settings” in your vehicle. This menu based system will
guide you through the steps necessary to retract the EPB
actuator in order to perform rear brake service.Brake Service Mode has requirements that must be met in
order to be activated:
•
The vehicle must be at a standstill.
• The park brake must be unapplied.
• The transmission must be in PARK or NEUTRAL.
While in service mode, the Electric Park Brake fault lamp
will flash continuously while the ignition switch is ON.
When brake service work is complete, the following steps
must be followed to reset the parking brake system to
normal operation:
• Ensure the vehicle is at a standstill.
• Press the brake pedal with moderate force.
• Apply the Electric Park Brake Switch.
WARNING!
You can be badly injured working on or around a
motor vehicle. Do only that service work for which you
have the knowledge and the right equipment. If you
have any doubt about your ability to perform a service
job, take your vehicle to a competent mechanic.
332 STARTING AND OPERATING

Transmission Limp Home Mode
Transmission function is monitored electronically for ab-
normal conditions. If a condition is detected that could
result in transmission damage, Transmission Limp Home
Mode is activated. In this mode, the transmission may
operate only in a fixed gear, or may remain in NEUTRAL.
The Malfunction Indicator Light (MIL) may be illuminated.
Limp Home Mode may allow the vehicle to be driven to an
authorized dealer for service without damaging the trans-
mission.
In the event of a momentary problem, the transmission can
be reset to regain all forward gears by performing the
following steps:
1. Stop the vehicle.
2. Shift the transmission into PARK, if possible. If not, shiftthe transmission to NEUTRAL.
3. Push and hold the ignition switch until the engine turns OFF.
4. Wait approximately 30 seconds.
5. Restart the engine. 6. Shift into the desired gear range. If the problem is no
longer detected, the transmission will return to normal
operation.
NOTE: Even if the transmission can be reset, we recom-
mend that you visit an authorized dealer at your earliest
possible convenience. An authorized dealer has diagnostic
equipment to assess the condition of your transmission. If
the transmission cannot be reset, authorized dealer service
is required.
Torque Converter Clutch
A feature designed to improve fuel economy has been
included in the automatic transmission on your vehicle. A
clutch within the torque converter engages automatically
at calibrated speeds. This may result in a slightly different
feeling or response during normal operation in the upper
gears. When the vehicle speed drops or during some
accelerations, the clutch automatically disengages.
NOTE: The torque converter clutch will not engage until
the engine and/or transmission is warm (usually after 1 to
3 miles [2 to 5 km] of driving). Because the engine speed is
higher when the torque converter clutch is not engaged, it
may seem as if the transmission is not shifting properly
when the vehicle is cold. This is normal. The torque
340 STARTING AND OPERATING

converter clutch will function normally once the pow-
ertrain is sufficiently warm.
ACTIVE NOISE CANCELLATION
Your vehicle is equipped with an Active Noise Cancellation
System. This system is designed to address exhaust and
engine noise. The system relies on four microphones
embedded in the headliner, which monitor exhaust and
engine noise, and assists an onboard frequency generator,
which creates counteracting sound waves in the audio
system’s speakers. This helps keep the vehicle quiet at idle
and during drive.
POWER STEERING
The electric power steering system will give you good
vehicle response and increased ease of maneuverability in
tight spaces. The system will vary its assist to provide light
efforts while parking and good feel while driving. If the
electric steering system experiences a fault that reduces
assist or prevents the vehicle from providing assist, you
will still have the ability to steer the vehicle manually.
WARNING!
Continued operation with reduced assist could pose a
safety risk to yourself and others. Service should be
obtained as soon as possible.
If the Steering icon is displayed and the “POWER STEER-
ING SYSTEM OVER TEMP” message is displayed on the
instrument cluster screen, they indicate that extreme steer-
ing maneuvers may have occurred which caused an over
temperature condition in the power steering system. Once
driving conditions are safe, pull over and let the vehicle
idle for a few moments until the icon and message turn off.
Refer to “Instrument Cluster Display” in “Getting To Know
Your Instrument Panel” for further information. If the “SERVICE POWER STEERING OR
POWER STEERING ASSIST OFF - SERVICE
SYSTEM” message and a steering wheel icon are
displayed on the instrument cluster screen, it
indicates that the vehicle needs to be taken to the dealer for
service. It is likely the vehicle has lost power steering
assistance. Refer to “Warning Lights And Messages” in
“Getting To Know Your Instrument Panel” for further
information.

STARTING AND OPERATING 341

NOTE:
•Even if the power steering assistance is no longer
operational, it is still possible to steer the vehicle. Under
these conditions there will be a substantial increase in
steering effort, especially at low speeds and during
parking maneuvers.
• The power steering system is fully electric; it requires no
power steering fluid.
• If the condition persists, see your authorized dealer for
service.
STOP/START SYSTEM — IF EQUIPPED
The Stop/Start function is developed to reduce fuel con-
sumption. The system will stop the engine automatically
during a vehicle stop if the required conditions are met.
Releasing the brake pedal, pressing the accelerator pedal or
shifting out of DRIVE (D) will automatically re-start the
engine.
This vehicle has been upgraded with a heavy duty starter,
enhanced battery, and other upgraded engine parts, to
handle the additional engine starts.
Auto Stop/Start
The Stop/Start feature is enabled after every
normal customer engine start. At that time, the
system will go into STOP/START READY and if
all other conditions are met, can go into a STOP/
START AUTOSTOP ACTIVE.
To Activate Auto STOP/START, The Following Must
Occur:
• The system must be in STOP/START READY state. A
STOP/START READY message will be displayed in the
instrument cluster within the Stop/Start section. Refer to
“Instrument Cluster Display” in “Getting To Know Your
Instrument Panel” for further information.
• The vehicle must be completely stopped.
• The shifter must be in a forward gear and the brake
pedal depressed.
The engine will shut down, the tachometer will move to
the zero position and the Stop/Start telltale will illuminate
indicating you are in Autostop. Customer settings will be
maintained throughout the Auto Stop/Start process.
342 STARTING AND OPERATING

4. The STOP/START system will reset itself back to an ONcondition every time the ignition is turned off and back
on.
Automatic Shutdown
This vehicle is equipped with an automatic shutdown
feature. If the vehicle is left in READY mode (vehicle
running) with the gear selector in PARK for one hour after
the driver exits, this feature will automatically turn the
vehicle off. Notifications have been added into this feature
to raise awareness of the timed event:
• In the interior of the vehicle, the instrument cluster will
display “Ready To Drive”, and will be accompanied by
three audible chimes while exiting. These interior warn-
ings will occur regardless of whether the key fob re-
mains in the vehicle or is removed.
• For the exterior of the vehicle, the horn will sound three
times if the fob is removed from the vehicle and the
vehicle is in the “READY” mode.
Please consider this feature when intentionally running the
vehicle for extended periods of time over one hour. To
restart the vehicle, follow the normal vehicle starting
process. NOTE:
If the vehicle is left in the ACC or RUN (engine not
running) position and the transmission is in PARK, the
system will automatically time out (shut down) after an
initial 30 minutes of inactivity, followed by the additional
amount of time for power accessory delay selected in the
radio settings menu. Once the vehicle times out, it will
switch to the OFF position.
To Manually Turn On The Stop/Start System
After turning off the STOP/START system, push the
STOP/START OFF switch again (located on the instrument
panel). The light on the switch will turn off.
System Malfunction
If there is a malfunction in the STOP/START system, the
system will not shut down the engine. A “SERVICE STOP/
START SYSTEM” message will appear in the instrument
cluster display and the Stop/Start telltale will remain
yellow. Refer to “Instrument Cluster Display” in “Getting
To Know Your Instrument Panel” for further information.
If the “SERVICE STOP/START SYSTEM” message appears
in the instrument cluster display, have the system checked
by your authorized dealer.

Display Warnings And Maintenance
“Wipe Front Radar Sensor In Front Of Vehicle”
Warning
The “ACC/FCW Unavailable Wipe Front Radar Sensor”
warning will display and also a chime will indicate when
conditions temporarily limit system performance.
This most often occurs at times of poor visibility, such as in
snow or heavy rain. The ACC system may also become
temporarily blinded due to obstructions, such as mud, dirt
or ice. In these cases, the instrument cluster display will
show “ACC/FCW Unavailable Wipe Front Radar Sensor”
and the system will deactivate.
The “ACC/FCW Unavailable Wipe Front Radar Sensor”
message can sometimes be displayed while driving in
highly reflective areas (i.e. tunnels with reflective tiles, or
ice and snow). The ACC system will recover after the
vehicle has left these areas. Under rare conditions, when
the radar is not tracking any vehicles or objects in its path
this warning may temporarily occur.
NOTE:If the “ACC/FCW Unavailable Wipe Front Radar
Sensor” warning is active Normal (Fixed Speed) Cruise
Control is still available. For additional information refer to “Normal (Fixed Speed) Cruise Control Mode” in this
section.
If weather conditions are not a factor, the driver should
examine the sensor. It may require cleaning or removal of
an obstruction. The sensor is located in the center of the
vehicle behind the lower grille.
To keep the ACC System operating properly, it is important
to note the following maintenance items:
•
Always keep the sensor clean. Carefully wipe the sensor
lens with a soft cloth. Be cautious not to damage the
sensor lens.
• Do not remove any screws from the sensor. Doing so
could cause an ACC system malfunction or failure and
require a sensor realignment.
• If the sensor or front end of the vehicle is damaged due
to a collision, see your authorized dealer for service.
•
Do not attach or install any accessories near the sensor,
including transparent material or aftermarket grilles. Do-
ing so could cause an ACC system failure or malfunction.
360 STARTING AND OPERATING

When the condition that deactivated the system is no
longer present, the system will return to the “Adaptive
Cruise Control Off” state and will resume function by
simply reactivating it.
NOTE:If the “ACC/FCW Unavailable Wipe Front Radar
Sensor” message occurs frequently (e.g. more than once on
every trip) without any snow, rain, mud, or other obstruc-
tion, have the radar sensor realigned at your authorized
dealer.
“Clean Front Windshield” Warning
The “ACC/FCW Limited Functionality Clean Front Wind-
shield” warning will display and also a chime will indicate
when conditions temporarily limit system performance.
This most often occurs at times of poor visibility, such as in
snow or heavy rain and fog. The ACC system may also
become temporarily blinded due to obstructions, such as
mud, dirt, or ice on windshield, driving directly into the
sun and fog on the inside of glass. In these cases, the
instrument cluster display will show “ACC/FCW Limited
Functionality Clean Front Windshield” and the system will
have degraded performance.
The “ACC/FCW Limited Functionality Clean Front Wind-
shield” message can sometimes be displayed while driving
in adverse weather conditions. The ACC/FCW system will recover after the vehicle has left these areas. Under rare
conditions, when the camera is not tracking any vehicles or
objects in its path this warning may temporarily occur.
If weather conditions are not a factor, the driver should
examine the windshield and the camera located on the
back side of the inside rear view mirror. They may require
cleaning or removal of an obstruction.
When the condition that created limited functionality is no
longer present, the system will return to full functionality.
NOTE:
If the “ACC/FCW Limited Functionality Clean
Front Windshield” message occurs frequently (e.g. more
than once on every trip) without any snow, rain, mud, or
other obstruction, have the windshield and forward facing
camera inspected at your authorized dealer.
Service ACC/FCW Warning
If the system turns off, and the instrument cluster displays
“ACC/FCW Unavailable Service Required” or “Cruise/
FCW Unavailable Service Required”, there may be an
internal system fault or a temporary malfunction that
limits ACC functionality. Although the vehicle is still

Enabling And Disabling ParkSense
ParkSense can be enabled and disabled with the
ParkSense switch, located on the switch panel
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 sec-
onds. Refer to “Instrument Cluster Display” in “Getting To
Know Your Instrument Panel” for further information.
When the gear selector is moved to REVERSE and the
system is disabled, the instrument cluster display will
show the “PARKSENSE OFF” message for as long as the
vehicle is in REVERSE.
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 hard switch. The instrument cluster display will show
KeySense in Use Selected Feature Cannot be Disabled 
message.
Service The ParkSense Rear Park Assist System
During vehicle start up, when the ParkSense Rear Park
Assist System has detected a faulted condition, the instru-
ment cluster will actuate a single chime, once per ignition
cycle, and it will display the “PARKSENSE UNAVAIL-
ABLE WIPE REAR SENSORS” or the “PARKSENSE UN-
AVAILABLE SERVICE REQUIRED” message. Refer to “In-
strument Cluster Display” in “Getting To Know Your
Instrument Panel” for further information. When the gear
selector is moved to REVERSE and the system has detected
a faulted condition, the instrument cluster display will
show the PARKSENSE UNAVAILABLE WIPE REAR SEN-
SORS orPARKSENSE UNAVAILABLE SERVICE RE-
QUIRED message for five seconds while the vehicle is in
REVERSE. Under this condition, ParkSense will not oper-
ate and “PARKSENSE OFF” message will be displayed.
If “PARKSENSE UNAVAILABLE WIPE REAR SENSORS”
appears in the instrument cluster display make sure the
outer surface and the underside of the rear fascia/bumper
6
STARTING AND OPERATING 375

is clean and clear of snow, ice, mud, dirt or other obstruc-
tion and then cycle the ignition. If the message continues to
appear, see an authorized dealer.
If “PARKSENSE UNAVAILABLE SERVICE REQUIRED”
appears in the instrument cluster display, see an autho-
rized 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. Otherwise, you could damage the
sensors.
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 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.
• When you move the gear selector to the REVERSE
position and ParkSense is turned off, the instrument
cluster display will show “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 indication that an obstacle is behind the fascia/
bumper.
• ParkSense should be disabled when the liftgate is in the
open position.
376 STARTING AND OPERATING

•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.
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 respon-
sible 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 recommended
that the ball mount and hitch ball assembly 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
(Continued)
WARNING! (Continued)
hitch ball will be much closer to the obstacle than the
rear fascia when the loudspeaker sounds the con-
tinuous 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 recommended that the
driver looks over his/her shoulder when using
ParkSense.
