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 transmission 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 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.
316 STARTING AND OPERATING

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.
AUTOMATIC TRANSMISSION
WARNING!
•Never use the PARK position as a substitute for the
parking brake. Always apply the parking brake fully
when exiting the vehicle to guard against vehicle
movement and possible injury or damage.
(Continued)
WARNING! (Continued)
•Your vehicle could move and injure you and others if
it is not in PARK. Check by trying to move the
transmission gear selector out of PARK with the
brake pedal released. Make sure the transmission is
in PARK before exiting the vehicle.
• The transmission may not engage PARK if the ve-
hicle is moving. Always bring the vehicle to a
complete stop before shifting to PARK, and verify
that the transmission gear position indicator solidly
indicates PARK (P) without blinking. Ensure that the
vehicle is completely stopped, and the PARK posi-
tion is properly indicated, before exiting the vehicle.
• It is dangerous to shift out of PARK or NEUTRAL if
the engine speed is higher than idle speed. If your
foot is not firmly pressing the brake pedal, the
vehicle could accelerate quickly forward or in re-
verse. You could lose control of the vehicle and hit
someone or something. Only shift into gear when the
engine is idling normally and your foot is firmly
pressing the brake pedal.
• Unintended movement of a vehicle could injure
those in or near the vehicle. As with all vehicles, you

Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock system (BTSI) that holds the transmission gear
selector in PARK unless the brakes are applied. To shift the
transmission out of PARK, the engine must be running and
the brake pedal must be pressed. The brake pedal must
also be pressed to shift from NEUTRAL into DRIVE or
REVERSE when the vehicle is stopped or moving at low
speeds.
Nine-Speed Automatic Transmission
The transmission is controlled using a rotary electronic
gear selector located on the center console. The transmis-
sion gear selector has PARK, REVERSE, NEUTRAL,
DRIVE, and LOW shift positions. Using the LOW position
manually downshifts the transmission to a lower gear
based on vehicle speed. The transmission gear range
(PRNDL) is displayed both above the gear selector and in
the instrument cluster. To select a gear range, simply rotate
the gear selector. Push down on the gear selector and then
rotate it, to access the L position. You must also press the
brake pedal to shift the transmission out of PARK (or
NEUTRAL, when stopped or moving at low speeds). To shift past multiple gear ranges at once (such as PARK to
DRIVE), simply rotate the gear selector to the appropriate
detent. Select the DRIVE range for normal driving.
NOTE:
In the event of a mismatch between the gear
selector position and the actual transmission gear (for
example, driver selects PARK while driving), the position
indicator will blink continuously until the selector is re-
turned to the proper position, or the requested shift can be
completed.
The electronically-controlled transmission adapts its shift
schedule based on driver inputs, along with environmental
and road conditions. The transmission electronics are self-
calibrating; therefore, the first few shifts on a new vehicle
may be somewhat abrupt. This is a normal condition, and
precision shifts will develop within a few hundred miles
(kilometers).
The nine-speed transmission has been developed to meet
the needs of current and future FWD/AWD vehicles.
Software and calibration is refined to optimize the custom-
er ’s driving experience and fuel economy. By design, some
vehicle and driveline combinations utilize 9th gear only in
very specific driving situations and conditions.

STARTING AND OPERATING 319

CAUTION!
Towing the vehicle, coasting, or driving for any other
reason with the transmission in NEUTRAL can cause
severe transmission damage.
Refer to “Recreational Towing” in “Starting And Op-
erating” and “Towing A Disabled Vehicle” in “In Case
Of Emergency” for further information.
DRIVE (D)
This range should be used for most city and highway
driving. It provides the smoothest upshifts and downshifts,
and the best fuel economy. The transmission automatically
upshifts through all forward gears. The DRIVE position
provides optimum driving characteristics under all normal
operating conditions.
If the transmission temperature exceeds normal operating
limits, the transmission controller may modify the trans-
mission shift schedule, reduce engine torque, and/or ex-
pand the range of torque converter clutch engagement.
This is done to prevent transmission damage due to
overheating.If the transmission becomes extremely hot, the
Transmis-
sion Temperature Warning Light will illuminate, a warn-
ing message will appear in the instrument cluster, and the
transmission may operate differently until the transmission
cools down.
During cold temperatures, transmission operation may be
modified depending on engine and transmission tempera-
ture as well as vehicle speed. This feature improves warm
up time of the engine and transmission to achieve maxi-
mum 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 opera-
tion 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 downshift
for increased engine braking. To access the LOW position,
push down on the gear selector and rotate it fully clock-
wise.

STARTING AND OPERATING 323

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

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.

PARKSENSE REAR PARK ASSIST — IF EQUIPPED
The ParkSense Rear Park Assist system provides visual and
audible indications of the distance between the rear fascia
and a detected obstacle when backing up, e.g. during a
parking maneuver. If your vehicle is equipped with an
Automatic Transmission, the vehicle brakes may be auto-
matically applied and released when performing a reverse
parking maneuver if the system detects a possible collision
with an obstacle.
NOTE:
•The driver can override the automatic braking function
by pressing the gas pedal, turning ParkSense off via
ParkSense switch, or changing the gear while the auto-
matic brakes are being applied.
6
STARTING AND OPERATING 351

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
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.
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. If your
vehicle is equipped with an Automatic Transmission, the
vehicle brakes may be automatically applied and released
when performing a reverse parking maneuver if the sys-
tem detects a possible collision with an obstacle.
