WARNING!
could accelerate quickly forward or in
reverse. 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 should never
exit a vehicle while the engine is run-
ning. Before exiting a vehicle, always
come to a complete stop, then apply the
parking brake, shift the transmission
into PARK, and turn the ignition OFF.
When the ignition is in the OFF mode,
the transmission is locked in PARK, se-
curing the vehicle against unwanted
movement.
• When exiting the vehicle, always make
sure the ignition is in the OFF mode,
remove the key fob from the vehicle, and
lock the vehicle.
• Never leave children alone in a vehicle,
or with access to an unlocked vehicle.
Allowing children to be in a vehicle un-
WARNING!
attended is dangerous for a number of
reasons. A child or others could be seri-
ously or fatally injured. Children should
be warned not to touch the parking
brake, brake pedal or the transmission
gear selector.
• Do not leave the key fob in or near the
vehicle (or in a location accessible to
children), and do not leave the ignition
in the ACC or ON/RUN mode. A child
could operate power windows, other con-
trols, or move the vehicle.
Ignition Park Interlock
This vehicle is equipped with an Ignition Park
Interlock which requires the transmission to
be in PARK before the ignition can be turned
to the OFF mode. This helps the driver avoid
inadvertently leaving the vehicle without
placing the transmission in PARK. This sys-
tem also locks the transmission in PARK
whenever the ignition is in the OFF mode.NOTE:
The transmission is NOT locked in PARK
when the ignition is in the ACC mode (even
though the engine will be off). Ensure that
the transmission is in PARK, and the ignition
isOFF(not in ACC mode) before exiting the
vehicle.
Brake/Transmission Shift Interlock
System
This vehicle is equipped with a Brake Trans-
mission 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.
Eight–Speed Automatic Transmission
Your vehicle is equipped with a fuel efficient
8 speed transmission. The gear selector is
located in the center console.

For additional information on the appropriate
use of each transfer case mode position, see
the information below:
2H
Rear Wheel Drive High Range — This range is
for normal street and highway driving on dry,
hard surfaced roads.
4H
Four-Wheel Drive High Range — This range
maximizes torque to the front driveshaft,
forcing the front and rear wheels to rotate at
the same speed. This range provides addi-
tional traction for loose, slippery road sur-
faces only.
NEUTRAL (N)
WARNING!
You or others could be injured or killed if
you leave the vehicle unattended with the
transfer case in the NEUTRAL (N) position
without first fully engaging the parking
brake. The transfer case NEUTRAL (N)
position disengages both the front and rear
driveshafts from the powertrain, and will
WARNING!
allow the vehicle to roll, even if the auto-
matic transmission is in PARK. The park-
ing brake should always be applied when
the driver is not in the vehicle.
Neutral — This range disengages both the
front and rear driveshafts from the pow-
ertrain. To be used for flat towing behind
another vehicle.
Refer to “Recreational Towing” in “Starting
And Operating” for further information.
4L
Four-Wheel Drive Low Range — This range
provides low speed four-wheel drive. It maxi-
mizes torque to the front driveshaft, forcing
the front and rear wheels to rotate at the same
speed. This range provides additional trac-
tion and maximum pulling power for loose,
slippery road surfaces only. Do not exceed
25 mph (40 km/h).
The transfer case is intended to be driven in
the 2H position for normal street and highway
conditions, such as hard-surfaced roads.In the event that additional traction is re-
quired, the transfer case 4H and 4L positions
can be used to lock the front and rear drive-
shafts together, forcing the front and rear
wheels to rotate at the same speed. The 4H
and 4L positions are intended for loose, slip-
pery road surfaces only and not intended for
normal driving. Driving in the 4H and 4L
positions on hard-surfaced roads will cause
increased tire wear and damage to the drive-
line components. Refer to “Shifting Proce-
dures” in this section for further information
on shifting into 4H or 4L.
The instrument cluster alerts the driver that
the vehicle is in four-wheel drive, and the
front and rear driveshafts are locked together.
The light will illuminate when the transfer
case is shifted into the 4H position.
When operating your vehicle in 4L, the en-
gine speed will be approximately three times
(four times for Rubicon models) that of the
2H or 4H positions at a given road speed.
Take care not to overspeed the engine.

Five-Position Transfer Case
The transfer case provides five mode posi-
tions:
• 2H (Two-Wheel Drive High Range)
•
4H Auto (Four-Wheel Drive Auto High Range)
• 4H PT (Four-Wheel Drive Part Time High
Range)
• N (Neutral)
• 4L (Four-Wheel Drive Low Range)For additional information on the appropriate
use of each transfer case mode position, see
the information below:
2H
Rear Wheel Drive High Range — This range is
for normal street and highway driving on dry,
hard surfaced roads.
4H AUTO
Four-Wheel Drive Auto High Range — This
range sends power to the front wheels. The
four-wheel drive system will be automatically
engaged when the vehicle senses a loss of
traction. Additional traction for varying road
conditions.
4H P-T
Four-Wheel Drive Part Time High Range —
This range maximizes torque to the front
driveshaft, forcing the front and rear wheels
to rotate at the same speed. This range pro-
vides additional traction for loose, slippery
road surfaces only.NEUTRAL (N)
WARNING!
You or others could be injured or killed if
you leave the vehicle unattended with the
transfer case in the NEUTRAL (N) position
without first fully engaging the parking
brake. The transfer case NEUTRAL (N)
