tain operating conditions), the transmis-
sion may use second gear (rather than first
gear) during launches, to minimize wheel
slippage.
• Sport — This mode alters the transmis-
sion's automatic shift schedule for sportier
driving. Upshift speeds are increased to
make full use of available engine power.
NOTE:
SPORT mode is not available when 4WD LOW
is selected.
• Sand/Mud — Off-road calibration for use on
low traction surfaces such as mud, sand, or
wet grass. Driveline is maximized for trac-
tion. Some binding may be felt on less
forgiving surfaces. The electronic brake
controls are set to limit traction control
management of throttle and wheel spin.
• Rock — Off-road calibration only available
in 4WD LOW range. Traction based tuning
with improved steer-ability for use on high
traction off-road surfaces. Use for low
speed obstacles such as large rocks, deep
ruts, etc. NOTE:
• Rock mode is only available on the vehicles
equipped with the Off-Road package.
• Activate the Hill Descent Control or Selec Speed Control for steep downhill control.
See “Electronic Brake Control System” in
“Safety” for further information.
STOP/START SYSTEM —
IF EQUIPPED
The Stop/Start function was developed to
reduce fuel consumption. The system will
stop the engine automatically during a ve-
hicle stop if the required conditions are met.
Releasing the brake pedal or pressing the
accelerator pedal will automatically restart
the engine.
This vehicle has been upgraded with a Heavy
Duty Battery, Starter, as well as other engine
parts, to handle the Additional engine starts.
Automatic Mode
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 “Au-
tostop” mode.
To Activate The Autostop Mode, The Following
Must Occur:
• The system must be in STOP/STARTREADY state. A STOP/START READY mes-
sage will be displayed in the instrument
cluster display within the Stop/Start sec-
tion. Refer to “Warning Lights And Mes-
sages” in “Getting To Know Your Instru-
ment Panel” in your Owner’s Manual.
• The vehicle must be completely stopped.
• The gear selector 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 upon return to an engine running
condition.
STARTING AND OPERATING

provide visual warnings in the instrument
cluster display and a torque warning in the
steering wheel if an unintentional lane de-
parture occurs.
• When the LaneSense system senses a lane drift situation, the left thick lane line and
left thin line turn solid yellow. The Lane-
Sense telltale changes from solid green to
solid yellow. At this time torque is applied
to the steering wheel in the opposite direc-
tion of the lane boundary.
For example: If approaching the left side of
the lane the steering wheel will turn to the
right.
• When the LaneSense system senses the lane has been approached and is in a lane
departure situation, the left thick lane line
flashes yellow (on/off) and the left thin line
remains solid yellow. The LaneSense tell-
tale changes from solid yellow to flashing
yellow. At this time torque is applied to the
steering wheel in the opposite direction of
the lane boundary.
For example: If approaching the left side of
the lane the steering wheel will turn to the
right. NOTE:
The LaneSense system operates with the
similar behavior for a right lane departure.
Changing LaneSense Status
The LaneSense system has settings to adjust
the intensity of the torque warning and the
warning zone sensitivity (early/late) that you
can configure through the Uconnect system
screen. Refer to “Uconnect Settings” in
“Multimedia” in your Owner’s Manual for
further information.
NOTE:
• When enabled the system operates above
37 mph (60 km/h) and below 112 mph
(180 km/h).
• Use of the turn signal suppresses the warn- ings.
• The system will not apply torque to the steering wheel whenever a safety system
engages (anti-lock brakes, traction control
system, electronic stability control, forward
collision warning, etc.).
PARKVIEW REAR BACK-UP
CAMERA
Symbols And Messages On The Display
You can see an on-screen image of the rear of
your vehicle whenever the transmission is
shifted into REVERSE. The ParkView Rear
Back-Up Camera image will be displayed on

It is recommended you contact an authorized
tire dealer or original equipment dealer with
any questions you may have on tire specifi-
cations or capability. Failure to use equiva-
lent replacement tires may adversely affect
the safety, handling, and ride of your vehicle.
WARNING!
• Do not use a tire, wheel size, load rating,or speed rating other than that specified
for your vehicle. Some combinations of
unapproved tires and wheels may
change suspension dimensions and per-
formance characteristics, resulting in
changes to steering, handling, and brak-
ing of your vehicle. This can cause un-
predictable handling and stress to steer-
ing and suspension components. You
could lose control and have a collision
resulting in serious injury or death. Use
only the tire and wheel sizes with load
ratings approved for your vehicle.
• Never use a tire with a smaller load index
or capacity, other than what was origi-
nally equipped on your vehicle. Using a
tire with a smaller load index could re-
WARNING!
sult in tire overloading and failure. You
could lose control and have a collision.
• Failure to equip your vehicle with tires
having adequate speed capability can
result in sudden tire failure and loss of
vehicle control.
CAUTION!
Replacing original tires with tires of a
different size may result in false speedom-
eter and odometer readings.
Tire Types
All Season Tires — If Equipped
All Season tires provide traction for all sea-
sons (Spring, Summer, Fall, and Winter).
Traction levels may vary between different all
season tires. All season tires can be identi-
fied by the M+S, M&S, M/S or MS designa-
tion on the tire sidewall. Use all season tires
only in sets of four; failure to do so may
adversely affect the safety and handling of
your vehicle.
Summer Or Three Season Tires —
If Equipped
Summer tires provide traction in both wet
and dry conditions, and are not intended to
be driven in snow or on ice. If your vehicle is
equipped with Summer tires, be aware these
tires are not designed for Winter or cold
driving conditions. Install Winter tires on your
vehicle when ambient temperatures are less
than 40°F (5°C) or if roads are covered with
ice or snow. For more information, contact an
authorized dealer.
Summer tires do not contain the all season
designation or mountain/snowflake symbol
on the tire sidewall. Use Summer tires only in
sets of four; failure to do so may adversely
affect the safety and handling of your vehicle.
WARNING!
Do not use Summer tires in snow/ice con-
ditions. You could lose vehicle control,
resulting in severe injury or death. Driving
too fast for conditions also creates the
possibility of loss of vehicle control.

• The use of 7mm snow chains is permittedwith 225/60R17 and 225/55R18 tires.
Four Wheel Drive (4WD) Trailhawk Models
• The use of 9mm snow chains is permitted with the use of 225/65R17 tires on size
17 x 7.5 ET31 wheels.
CAUTION!
• Use on Front Tires Only
• Damage to Front Wheel Drive (FWD) Models may result if tire chains or trac-
tion devices are used with original
equipment size tires.
• Damage to Four Wheel Drive (4WD)
Models without a Two-Speed Power
Takeoff Unit may result if tire chains or
traction devices are used with original
equipment size tires.
• Damage to Four Wheel Drive (4WD)
Trailhawk Models may result if tire
chains or traction devices are used with
original equipment size tires.
WARNING!
Using tires of different size and type
(M+S, Snow) between front and rear axles
can cause unpredictable handling. You
could lose control and have a collision.
CAUTION!
To avoid damage to your vehicle or tires,
observe the following precautions:
• Because of restricted traction deviceclearance between tires and other sus-
pension components, it is important
that only traction devices in good condi-
tion are used. Broken devices can cause
serious damage. Stop the vehicle imme-
diately if noise occurs that could indi-
cate device breakage. Remove the dam-
aged parts of the device before further
use.
• Install device as tightly as possible and
then retighten after driving about ½ mile
(0.8 km).
• Do not exceed 30 mph (48 km/h).
CAUTION!
• Drive cautiously and avoid severe turns
and large bumps, especially with a
loaded vehicle.
• Do not drive for a prolonged period on
dry pavement.
• Observe the traction device manufactur-
er’s instructions on the method of instal-
lation, operating speed, and conditions
for use. Always use the suggested oper-
ating speed of the device manufacturer’s
if it is less than 30 mph (48 km/h).
• Do not use traction devices on a com-
pact spare tire.
Tire Rotation Recommendations
The tires on the front and rear of your vehicle
operate at different loads and perform differ-
ent steering, handling, and braking func-
tions. For these reasons, they wear at unequal
rates.
These effects can be reduced by timely rota-
tion of tires. The benefits of rotation are
especially worthwhile with aggressive tread
designs such as those on On/Off Road typeSERVICING AND MAINTENANCE
