32GETTING TO KNOW YOUR VEHICLE
Easy Entry/Exit Seat — If Equipped
This feature provides automatic driver seat
positioning to enhance driver mobility when
entering and exiting the vehicle.
The distance the driver seat moves depends on
where you have the driver seat positioned when
you place the vehicle’s ignition in the OFF position.
When you place the vehicle’s ignition in the OFF
position, the driver seat will move about
2.4 inches (6.1 cm) rearward if the driver seat
position is greater than or equal to 2.7 inches
(6.8 cm) forward of the rear stop. The seat will
return to its previously set position when you
place the vehicle’s ignition in the ACC or RUN
position.
The Easy Entry/Easy Exit feature is disabled
when the driver seat position is less than 0.9 of
an inch (2.3 cm) forward of the rear stop. At this
position, there is no benefit to the driver by
moving the seat for Easy Exit or Easy Entry.
When enabled in Uconnect Settings, Easy Entry
and Easy Exit positions are stored in each memory
setting profile Ú page 27.
NOTE:The Easy Entry/Exit feature is enabled or disabled
through the programmable features in the
Uconnect system Ú page 120.
HEATED SEATS — IF EQUIPPED
On some models, the front seats may be equipped
with heaters located in the seat cushions and
seatbacks.
Front Heated Seats
The front heated seats control buttons are located
within the Uconnect system. You can gain access
to the control buttons through the climate screen
and the controls screen. You can choose from HI, LO, or OFF heat settings.
The indicator arrows in touchscreen buttons
indicate the level of heat in use. Two indicator
arrows will illuminate for HI, and one for LO.
Turning the heating elements off will return the
user to the radio screen.
Press the heated seat button once to turn
the HI setting on.
Press the heated seat button a second time
to turn the LO setting on.
Press the heated seat button a third time to
turn the heating elements off.

Once a heat setting is selected, heat will be felt
within two to five minutes.
The engine must be running for the heated
seats to operate.
If the HI-level setting is selected, the system will
automatically switch to LO-level after approxi-
mately 60 minutes of continuous operation. At
that time, the display will change from HI to LO,
indicating the change. The LO-level setting will
turn off automatically after approximately
45 minutes.
For information on use with the Remote Start
system, see Ú page 19.
WARNING!
Persons who are unable to feel pain to the
skin because of advanced age, chronic illness,
diabetes, spinal cord injury, medication,
alcohol use, exhaustion or other physical
condition must exercise care when using the
seat heater. It may cause burns even at low
temperatures, especially if used for long
periods of time.
Do not place anything on the seat or seatback
that insulates against heat, such as a blanket
or cushion. This may cause the seat heater to
overheat. Sitting in a seat that has been over -
heated could cause serious burns due to the
increased surface temperature of the seat.

EATING INSTALLED
All passenger occupants within the vehicle must be
in a seat equipped with a Seat Belt System and
Head Restraint for the safety of the passenger. If
the passenger and/or rear seats have been
removed, do not ride in those areas.
This vehicle has been designed to maximize total
performance. In doing so, the deletion of
passenger seats and/or rear seat may affect the
Noise, Vibration, and Harshness (NVH)
characteristics. As a result, the interior will be
louder overall.
WARNING!
Persons who are unable to feel pain to the
skin because of advanced age, chronic illness,
diabetes, spinal cord injury, medication,
alcohol use, exhaustion or other physical
condition must exercise care when using the
seat heater. It may cause burns even at low
temperatures, especially if used for long
periods of time.
Do not place anything on the seat or seatback
that insulates against heat, such as a blanket
or cushion. This may cause the seat heater to
overheat. Sitting in a seat that has been over -
heated could cause serious burns due to the
increased surface temperature of the seat.
WARNING!
If the passenger and/or rear seats have been
removed, do not ride in those areas. In a colli -
sion, people riding in these areas are more
likely to be seriously injured or killed.
If this vehicle was not factory equipped with a
passenger seat, NEVER attempt to install a
passenger seat because the safety systems,
including the air bags and seat belt, may not
properly protect you.
It is dangerous to ride in a cargo area, inside
or outside of a vehicle. In a collision, people
riding in this area are more likely to be seri -
ously injured or killed.
Only ride in available seating positions
equipped with seat belt systems. Always prop -
erly wear your seat belt. Failure to do so could
result in an increased risk of serious injury or
death in the event of an accident.
Be sure everyone in your vehicle is in a seat
and using a seat belt properly. Occupants,
including the driver, should always wear their
seat belts whether or not an air bag is also
provided at their seating positions to minimize
the risk of severe injury or death in the event
of a crash.

PROGRAMMING HOMELINK® TO A
M
ISCELLANEOUS DEVICE
Follow the procedure on programming HomeLink®
to a garage door opener Ú page 39. Be sure to
determine if the device has a rolling code, or
non-rolling code before beginning the
programming process.
NOTE:Canadian radio frequency laws require transmitter
signals to time-out (or quit) after several seconds
of transmission, which may not be long enough for
HomeLink® to pick up the signal during
programming. Similar to this Canadian law, some
U.S. gate operators are designed to time-out in the
same manner. The procedure may need to be
performed multiple times to successfully pair the
device to your HomeLink® buttons.
REPROGRAMMING A SINGLE
H
OMELINK® BUTTON
To reprogram a single HomeLink® button that has
been previously trained, without erasing all the
channels, follow the procedure below. Be sure to
determine whether the new device you want to
program the HomeLink® button to has a rolling
code or non-rolling code.

1. Place the ignition in the ON/RUN position,
without starting the engine.

2. Push and hold the desired HomeLink® button until the HomeLink® Indicator light begins to
flash after 20 seconds. Do not release the
button.
3. Without releasing the button , proceed with
Step 2 in “Programming HomeLink® To A
Garage Door Opener” and follow all remaining
steps.
CANADIAN/GATE OPERATOR
P
ROGRAMMING
For programming transmitters in Canada/United
States that require the transmitter signals to
“time-out” after several seconds of transmission.
Canadian radio frequency laws require transmitter
signals to time-out (or quit) after several seconds
of transmission – which may not be long enough
for HomeLink® to pick up the signal during programming. Similar to this Canadian law, some
U.S. gate operators are designed to time-out in the
same manner.
It may be helpful to unplug the device during the
cycling process to prevent possible overheating of
the garage door or gate motor.

1. Place the ignition in the ON/RUN position.

2. Place the hand-held transmitter 1 to 3 inches
(3 to 8 cm) away from the HomeLink® button
you wish to program while keeping the
HomeLink® indicator light in view.
3. Continue to press and hold the HomeLink® button, while you press and release (cycle)
your hand-held transmitter every two seconds
until HomeLink® has successfully accepted
the frequency signal. The indicator light will
flash slowly and then rapidly when fully
trained.
4. Watch for the HomeLink® indicator to change flash rates. When it changes, it is
programmed. It may take up to 30 seconds or
longer in rare cases. The garage door may
open and close while you are programming.
5. Press and hold the programmed HomeLink® button and observe the indicator light.
Do not run your vehicle in a closed garage or
confined area while programming the trans -
ceiver. Exhaust gas from your vehicle contains
Carbon Monoxide (CO) which is odorless and
colorless. Carbon Monoxide is poisonous
when inhaled and can cause you and others to
be severely injured or killed.
WARNING!

92STARTING AND OPERATING
In some models, the shift paddles may be
disabled (or re-enabled, as desired) using Drive
Mode Set-Up, accessed by selecting Perfor -
mance Control.
In AutoStick mode, the transmission will shift up or
down when (+/-) is manually selected by the driver
(using the gear selector, or the shift paddles [if
equipped]), unless an engine lugging or overspeed
condition would result. It will remain in the selected
gear until another upshift or downshift is chosen,
except as described below.
In temporary AutoStick mode (gear selector in
DRIVE), the transmission will automatically shift
up when maximum engine speed is reached. If
the accelerator is fully pressed, the transmis -
sion will downshift when possible. Lack of accel -
erator pedal activity will cause the transmission
to revert to automatic operation.
If normal AutoStick mode is engaged (gear
selector in MANUAL position), manual gear
selection will be maintained until the gear
selector is returned to DRIVE, or as described
below. The transmission will not upshift auto -
matically at redline in this mode, nor will down -
shifts be obtained if the accelerator pedal is
pressed to the floor.
The transmission will automatically downshift
as the vehicle slows (to prevent engine lugging)
and will display the current gear.
The transmission will automatically downshift to
FIRST gear when coming to a stop. After a stop,
the driver should manually upshift (+) the trans -
mission as the vehicle is accelerated.
You can start out, from a stop, in FIRST or
SECOND gear. Tapping (+) (at a stop) will allow
starting in SECOND gear. Starting out in
SECOND gear can be helpful in snowy or icy
conditions.
If a requested downshift would cause the
engine to over-speed, that shift will not occur
and an indication will display.
The system will ignore attempts to upshift at too
low of a vehicle speed and an indication will
display.
Holding the (-) paddle pressed (if equipped), or
holding the gear selector in the (-) position, will
downshift the transmission to the lowest gear
possible at the current speed.
Transmission shifting will be more noticeable
when AutoStick is enabled.
The system may revert to automatic shift mode
if a fault or overheat condition is detected. To disengage AutoStick mode, return the gear
selector to the DRIVE position, or press and hold
the (+) shift paddle (if equipped, and the gear
selector is already in DRIVE) until “D” is once again
indicated in the instrument cluster. You can shift in
or out of the AutoStick mode at any time without
taking your foot off the accelerator pedal.
SPORT MODE — WITHOUT PERFORMANCE
CONTROL
Your vehicle is equipped with a SPORT Mode
feature. This mode is a configuration set up for
typical enthusiast driving. The engine,
transmission (when equipped with automatic
transmission), and steering systems are all set to
their SPORT settings. SPORT Mode will provide
improved throttle response and modified shifting
for an enhanced driving experience, as well the
greatest amount of steering feel. This mode may
be activated and deactivated by pushing the
SPORT button on the instrument panel switch
bank.
WARNING!
Do not downshift for additional engine braking
on a slippery surface. The drive wheels could
lose their grip and the vehicle could skid,
causing a collision or personal injury.
