•Engine temp too high.
• 5 MPH threshold not achieved from previous AU-
TOSTOP.
• Steering angle beyond threshold.
• ACC is on and speed is set.
It may be possible for the vehicle to be driven several
times without the STOP/START system going into a
STOP/START READY state under more extreme condi-
tions of the items listed above.
To Start The Engine While In Autostop Mode
While in a forward gear, the engine will start when the
brake pedal is released or the throttle pedal is depressed.
The transmission will automatically re-engage upon en-
gine restart. Conditions That Will Cause The Engine To Start Auto-
matically While In Autostop Mode:
•
The transmission selector is moved out of DRIVE.
• To maintain cabin temperature comfort.
• HVAC is set to full defrost mode.
• HVAC system temperature or fan speed is manually
adjusted.
• Battery voltage drops too low.
• Low brake vacuum (e.g. after several brake pedal
applications).
• STOP/START OFF switch is pressed.
• A STOP/START system error occurs.
• 4WD system is put into 4LO mode.

•Some ECO mode functions may be temporarily inhib-
ited based on temperature and other factors.
Eight-Speed Automatic Transmission
The transmission is controlled using a rotary electronic
gear selector located on the center console. The transmis-
sion gear range (PRND) is displayed both above the gear
selector and in the Driver Information Display (DID). To
select a gear range, simply rotate the gear selector. You
must also press the brake pedal to shift the transmission
out of PARK, or to shift from NEUTRAL into DRIVE or
REVERSE when the vehicle is stopped or moving at low
speeds (refer to “Brake/Transmission Shift Interlock Sys-
tem” in this section). 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. The electronically-controlled transmission provides a
precise shift schedule. 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).
Only shift from DRIVE to PARK or REVERSE when the
accelerator pedal is released and the vehicle is stopped.
Be sure to keep your foot on the brake pedal when
shifting between these gears.
The transmission gear selector has only PARK, REVERSE,
NEUTRAL, and DRIVE shift positions. Manual shifts can
be made using the AutoStick shift control (shift paddles
mounted on the steering wheel). Pressing the shift paddles
(-/+) while in the DRIVE range will manually select the

AutoStick
AutoStick is a driver-interactive transmission feature
providing manual shift control, giving you more control
of the vehicle. AutoStick allows you to maximize engine
braking, eliminate undesirable upshifts and downshifts,
and improve overall vehicle performance. This system
can also provide you with more control during passing,
city driving, cold slippery conditions, mountain driving,
trailer towing, and many other situations.
Operation
When the transmission is in DRIVE, it will operate
automatically, shifting between the eight available gears.
To engage AutoStick, simply tap one of the steering
wheel-mounted shift paddles (+/-). Tapping (-) to enter
AutoStick mode will downshift the transmission to the
next lower gear, while using (+) to enter AutoStick modewill retain the current gear. When AutoStick is active, the
current transmission gear is displayed in the instrument
cluster.
In AutoStick mode, the transmission will shift up or
down when (+/-) is manually selected by the driver,
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.
•
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 transmission as the
vehicle is accelerated.

Traction Downhill
Shift the transmission into a low gear, and the transfer
case into LOW range. Let the vehicle go slowly down the
hill with all four wheels turning against engine compres-
sion drag. This will permit you to control the vehicle
speed and direction.
When descending mountains or hills, repeated braking
can cause brake fade with loss of braking control. Avoid
repeated heavy braking by downshifting the transmis-
sion whenever possible.
After Driving Off-Road
Off-road operation puts more stress on your vehicle than
does most on-road driving. After going off-road, it is
always a good idea to check for damage. That way you
can get any problems taken care of right away and have
your vehicle ready when you need it.•
Completely inspect the underbody of your vehicle.
Check tires, body structure, steering, suspension, and
exhaust system for damage.
• Inspect the radiator for mud and debris and clean as
required.
• Check threaded fasteners for looseness, particularly on
the chassis, drivetrain components, steering, and sus-
pension. Retighten them, if required, and torque to the
values specified in the Service Manual.
• Check for accumulations of plants or brush. These
things could be a fire hazard. They might hide damage
to fuel lines, brake hoses, axle pinion seals, and
propeller shafts.
• After extended operation in mud, sand, water, or
similar dirty conditions, have the radiator, fan, brake
rotors, wheels, brake linings, and axle yokes inspected
and cleaned as soon as possible.

WARNING!
Abrasive material in any part of the brakes may cause
excessive wear or unpredictable braking. You might
not have full braking power when you need it to
prevent a collision. If you have been operating your
vehicle in dirty conditions, get your brakes checked
and cleaned as necessary.
• If you experience unusual vibration after driving in
mud, slush or similar conditions, check the wheels for
impacted material. Impacted material can cause a
wheel imbalance and freeing the wheels of it will
correct the situation.
ELECTRIC 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 prevents it
from providing assist, you will still have the ability to steer
the vehicle manually.
Alternate electric power steering efforts can be selected
through the Uconnect System. Refer to ”Customer Program-
mable Features” within “Uconnect Settings” in “Under-
standing Your Instrument Panel” for further information.
WARNING!
Continued operation with reduced assist could pose
a safety risk to yourself and others. Service should be
obtained as soon as possible.
