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. Auto Park
Brake is enabled and disabled by customer selection
through the “Customer Programmable Features” section
of the “Uconnect Settings”.
SafeHold
SafeHold is a safety feature of the Electric Park Brake
System that will engage the park brake automatically if
the vehicle is left unsecured. If the automatic transmis-
sion is not in PARK, the seat belt is unbuckled, the driver
door is open, the vehicle is at a standstill, and there is no
attempt 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 openand 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
service.
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 me-
chanic.
AUTOMATIC TRANSMISSION
CAUTION!
Damage to the transmission may occur if the follow-
ing precautions are not observed:
•Shift into or out of PARK or REVERSE only after
the vehicle has come to a complete stop.

and/or expand the range of torque converter clutch
engagement. This is done to prevent transmission dam-
age due to overheating.
If the transmission becomes extremely hot, theTransmis-
sion Temperature Warning Light will illuminate, a warn-
ing message will appear in the EVIC/DID and the
transmission may operate differently until the transmis-
sion cools down.
During cold temperatures, transmission operation may
be modified depending on engine and transmission
temperature as well as vehicle speed. This feature im-
proves warm up time of the engine and transmission to
achieve maximum efficiency. Engagement of the torque
converter clutch, and shifts into 8th or 9th gear, are
inhibited until the transmission fluid is warm (refer to the
“Note” under “Torque Converter Clutch” in this section).
Normal operation will resume once the transmission
temperature has risen to a suitable level.LOW (L)
Use this range for engine braking when descending very
steep grades. In this range, the transmission will down-
shift for increased engine braking. To access the LOW
position, push down on the gear selector and rotate it
fully clockwise.
Transmission Limp Home Mode
Transmission function is monitored electronically for
abnormal 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 illumi-
nated. Limp Home Mode may allow the vehicle to be
driven to an authorized dealer for service without dam-
aging the transmission.
402 STARTING AND OPERATING

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,shift the 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 your authorized dealer at your
earliest possible convenience. Your authorized dealer has
diagnostic equipment to determine if the problem could
recur. 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 automati-
cally 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.
6
STARTING AND OPERATING 403

NOTE:The torque converter clutch will not engage until
the transmission fluid 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
cold. This is normal. The torque converter clutch will
function normally once the transmission is sufficiently
warm.
ACTIVE NOISE CANCELLATION
Your vehicle is equipped with an Active Noise Cancella-
tion 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.
404 STARTING AND OPERATING

If the “SERVICE POWER STEERINGOR
POWER STEERING ASSIST OFF - SERVICE
SYSTEM” message and a steering wheel icon
are displayed on the EVIC/DID 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 “Display” in “Getting To Know Your Instrument
Panel” for further information.
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.
• If the condition persists, see your authorized dealer for
service.SPEED CONTROL — IF EQUIPPED
When engaged, the Speed Control takes over accelerator
operations at speeds greater than 25 mph (40 km/h).
The Speed Control buttons are located on the right side of
the steering wheel.

•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.
Doing so could cause an ACC system failure or
malfunction.
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 Ra-
dar Sensor” message occurs frequently (e.g. more than
once on every trip) without any snow, rain, mud, or other
obstruction, have the radar sensor realigned at your
authorized dealer.
“Clean Front Windshield” Warning
The “ACC/FCW Limited Functionality Clean Front
Windshield” warning will display and also a chime will
indicate when conditions temporarily limit system per-
formance. This most often occurs at times of poor visibil-
ity, 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 EVIC/DID will display “ACC/
FCW Limited Functionality Clean Front Windshield” and
the system will have degraded performance.
426 STARTING AND OPERATING

The “ACC/FCW Limited Functionality Clean Front
Windshield” 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 function-
ality.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 EVIC/DID 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
drivable under normal conditions, ACC will be tempo-
rarily unavailable. If this occurs, try activating ACC again
later, following an ignition cycle. If the problem persists,
see your authorized dealer.

System will reject customer input to turn the system OFF
via the hard switch. The EVIC/DID will display Key-
Sense in Use Selected Feature Cannot be Disabled mes-
sage.
Service The ParkSense Rear Park Assist System
During vehicle start up, when the ParkSense Rear Park
Assist 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” or the
“PARKSENSE UNAVAILABLE SERVICE REQUIRED”
message. Refer to “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 EVIC/DID will display
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
operate and will read “OFF” over the arcs.
If “PARKSENSE UNAVAILABLE WIPE REAR SEN-
SORS” appears in the Electronic Vehicle Information
Center (EVIC) or Driver Information Display (DID) make
sure the outer surface and the underside of the rear
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.
