The transmission will automatically down-
shift to FIRST gear when coming to a stop.
After a stop, the driver should manually
upshift (+) the transmission as the vehicle
is accelerated.
You can start out, from a stop, in FIRST or
SECOND gear (or THIRD gear, in 4L
range). Tapping (+) (at a stop) will allow
starting in SECOND gear. Starting out in
SECOND or THIRD 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.
The system will ignore attempts to upshift
at too low of a vehicle speed.
Holding the gear selector in the (-) posi -
tion will downshift the transmission to the
lowest gear possible at the current speed.
Transmission shifting will be more notice-
able when AutoStick is enabled.
The system may revert to automatic shift
mode if a fault or overheat condition is
detected. NOTE:
When Hill Descent Control is enabled, Auto
-
Stick is not active.
To disengage AutoStick mode, return the
gear selector to the DRIVE position. You can
shift in or out of the AutoStick position at any
time without taking your foot off the acceler -
ator pedal.
FOUR–WHEEL DRIVE
OPERATION
Four-Position Transfer Case
Four-Wheel Drive Gear Selector
The transfer case provides four mode posi -
tions:
2H (Two-Wheel Drive High Range)
4H (Four-Wheel Drive 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
Two-Wheel Drive High Range — This range is
for normal street and highway driving on dry,
hard surfaced roads.
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.
WARNING!
Failure to engage a transfer case position
completely can cause transfer case
damage or loss of power and vehicle
control. You could have a collision. Do not
drive the vehicle unless the transfer case
is fully engaged.

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
surfaces only.
NEUTRAL (N)
Neutral — This range disengages both the
front and rear driveshafts from the power -
train. To be used for flat towing behind
another vehicle.
Refer to “Recreational Towing” in this
chapter 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
traction 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
required, the transfer case 4H and 4L posi -
tions can be used to lock the front and rear
driveshafts together, forcing the front and
rear wheels to rotate at the same speed. The
4H and 4L positions are intended for loose,
slippery 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
engine 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.
Proper operation of four-wheel drive vehicles
depends on tires of equal size, type, and
circumference on each wheel. Any difference
will adversely affect shifting and cause
damage to the transfer case.
Because four-wheel drive provides improved
traction, there is a tendency to exceed safe
turning and stopping speeds. Do not go
faster than road conditions permit.
Shifting Procedures
2H To 4H Or 4H To 2H
Shifting between 2H and 4H can be made
with the vehicle stopped or in motion. The
preferred shifting speed would be 0 to
45 mph (72 km/h). With the vehicle in
motion, the transfer case will engage/disen
-
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
allow the vehicle to roll, even if the
automatic transmission is in PARK. The
parking brake should always be applied
when the driver is not in the vehicle.

gage faster if you momentarily release the
accelerator pedal after completing the shift.
Do not accelerate while shifting the transfer
case. Apply a constant force when shifting
the transfer case lever.
NOTE:
Do not attempt to make a shift while only the
front or rear wheels are spinning. The front
and rear driveshaft speeds must be equal for
the shift to take place. Shifting while only
the front or rear wheels are spinning can
cause damage to the transfer case.
Delayed shifts out of four-wheel drive may
be experienced due to uneven tire wear,
low or uneven tire pressures, excessive
vehicle loading, or cold temperatures.
Shifting effort will increase with speed,
this is normal.
During cold weather, you may experience
increased effort in shifting until the transfer
case fluid warms up. This is normal.
4H To 4L Or 4L To 4H
With the vehicle rolling at 2 to 3 mph (3 to
5 km/h), shift the transmission into
NEUTRAL (N). While the vehicle is coasting
at 2 to 3 mph (3 to 5 km/h), shift the
transfer case lever firmly to the desired posi -
tion. Do not pause with the transfer case in
N (Neutral). Once the shift is completed,
place the transmission into DRIVE.
NOTE:
Shifting into or out of 4L is possible with the
vehicle completely stopped; however, diffi -
culty may occur due to the mating teeth not
being properly aligned. Several attempts may
be required for clutch teeth alignment and
shift completion to occur. The preferred
method is with the vehicle rolling at 2 to
3 mph (3 to 5 km/h). Avoid attempting to
engage or disengage 4L with the vehicle
moving faster than 2 to 3 mph (3 to 5 km/h).
Five-Position Transfer Case
Four-Wheel Drive Gear Selector
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)
WARNING!
Failure to engage a transfer case position
completely can cause transfer case damage or
loss of power and vehicle control. You could
have a collision. Do not drive the vehicle unless
the transfer case is fully engaged.

For additional information on the appropriate
use of each transfer case mode position, see
the information below:
2H
Two-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 PT
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
provides additional traction for loose, slip-
pery road surfaces only. NEUTRAL (N)
Neutral — This range disengages both the
front and rear driveshafts from the power
-
train. To be used for flat towing behind
another vehicle.
Refer to “Recreational Towing” in this
chapter 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
traction and maximum pulling power for
loose, slippery road surfaces only. Do not
exceed 25 mph (40 km/h).
This transfer case is designed to be driven in
the 2H mode or 4H AUTO mode for normal
street and highway conditions on dry hard
surfaced roads. Driving the vehicle in 2H will
have greater fuel economy benefits as the
front axle is not engaged in 2H.
For variable driving conditions, the 4H AUTO
mode can be used. In this mode, the front
axle is engaged, but the vehicle's power is
sent to the rear wheels. Four-wheel drive will
be automatically engaged when the vehicle
senses a loss of traction. Because the front
axle is engaged, this mode will result in lower
fuel economy than the 2H mode.
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
allow the vehicle to roll, even if the

(the “FRONT + REAR” will illuminate).
When the rear axle is locked, pushing the
bottom of switch again will lock or unlock the
front axle.
NOTE:
The indicator lights will flash until the axles
are fully locked or unlocked.
To unlock the axles, push the AXLE LOCK
OFF button.
Axle lock will disengage if the vehicle is

10 mph (16 km/h).
Electronic Sway Bar Disconnect — If
Equipped
Your vehicle may be equipped with an elec -
tronic disconnecting stabilizer/sway bar. This
system allows greater front suspension travel
in off-road situations. This system is controlled by the SWAY BAR
switch located on the instrument panel (to
the right of the steering column).
SWAY BAR Switch
Push the SWAY BAR switch to activate the
system. Push the switch again to deactivate
the system. The “Sway Bar Indicator Light”
(located in the instrument cluster) will illu -
minate when the bar is disconnected. The
“Sway Bar Indicator Light” will flash during
activation transition, or when activation
conditions are not met. The stabilizer/sway
bar should remain in on-road mode during
normal driving conditions. To disconnect the stabilizer/sway bar, shift to
either 4H or 4L and push the SWAY BAR
switch to obtain the off-road position. Refer
to “Four-Wheel Drive Operation” in this
section for further information. The “Sway
Bar Indicator Light” will flash until the stabi
-
lizer/sway bar has been fully disconnected.
WARNING!
Ensure the stabilizer/sway bar is
reconnected before driving on hard
surfaced roads or at speeds above 18 mph
(29 km/h); a disconnected stabilizer/sway
bar may contribute to the loss of vehicle
control, which could result in serious
injury. Under certain circumstances, the
front stabilizer/sway bar enhances vehicle
stability and assists with vehicle control.
The system monitors vehicle speed and
will attempt to reconnect the stabilizer/
sway bar at speeds over 18 mph (29 km/
h). This is indicated by a flashing or solid
“Sway Bar Indicator Light.” Once vehicle
speed is reduced below 14 mph (22 km/
h), the system will once again attempt to
return to off-road mode.
