When parking on a hill, it is important to turn the
front wheels toward the curb on a downhill grade
and away from the curb on an uphill grade. For
vehicles equipped with an automatic transmission,
apply the parking brake before placing the gear
selector in PARK, otherwise the load on the
transmission locking mechanism may make it
difficult to move the gear selector out of PARK.
MANUAL TRANSMISSION — IF EQUIPPED
WARNING!
Never use the PARK position on an automatic
transmission as a substitute for the parking
brake. Always apply the parking brake fully
when parked to guard against vehicle move-
ment and possible injury or damage.
When exiting the vehicle, always remove the
key fob from the vehicle and lock your vehicle.
Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing chil

DOWNSHIFTING
Moving from a high gear down to a lower gear is
recommended to preserve brakes when driving
down steep hills. In addition, downshifting at the
right time provides better acceleration when you
desire to resume speed. Downshift progressively.
Do not skip gears to avoid overspeeding the engine
and clutch.
NOTE:Above certain speeds, downshifts may be blocked
and not available.
Maximum Recommended Downshift
Speeds
NOTE:Vehicle speeds shown in the chart above are for
2H and 4H only, vehicle speeds in 4L would be
significantly less.
AUTOMATIC TRANSMISSION —
IF EQUIPPED
You must press and hold the brake pedal while
shifting out of PARK.
WARNING!
Do not downshift for additional engine braking
on a slippery surface. The drive wheels could
lose their grip, and the vehicle could skid.
CAUTION!
Skipping gears and downshifting into lower
gears at higher vehicle speeds can damage
the engine and clutch systems. Any attempt to
shift into lower gear with clutch pedal pressed
may result in damage to the clutch system.
Shifting into lower gear and releasing the
clutch may result in engine damage.
When descending a hill, be very careful to
downshift one gear at a time to prevent over -
speeding the engine which can cause engine
damage, and/or clutch damage, even if the
clutch pedal is pressed. If transfer case is in
low range the vehicle speeds to cause engine
and clutch damage are significantly lower.
Failure to follow the maximum recommended
downshifting speeds may cause engine
damage and/or damage the clutch, even if the
clutch pedal is pressed.
Descending a hill in low range with clutch
pedal pressed could result in clutch damage.
CAUTION!
Failure to follow the maximum recommended
downshifting speeds may cause the engine to
overspeed and/or damage the clutch disc, even
if the clutch pedal is pressed.

PARK (P)
This range supplements the parking brake by
locking the transmission. The engine can be
started in this range. Never attempt to use PARK
while the vehicle is in motion. Apply the parking
brake when exiting the vehicle in this range.
When parking on a hill, apply the parking brake
before shifting the transmission to PARK. As an
added precaution, turn the front wheels toward the
curb on a downhill grade and away from the curb
on an uphill grade.
When exiting the vehicle, always:
Apply the parking brake
Shift the transmission into PARK
Turn the ignition off
Remove the key fob from the vehicle
NOTE:On four-wheel drive vehicles, be sure that the
transfer case is in a drive position.
WARNING!
Never use the PARK position as a substitute
for the parking brake. Always apply the
parking brake fully when exiting the vehicle to
guard against vehicle movement and possible
injury or damage.
Your vehicle could move and injure you and
others if it is not in PARK. Check by trying to
move the transmission gear selector out of
PARK with the brake pedal released. Make
sure the transmission is in PARK before
exiting the vehicle.
The transmission may not engage PARK if the
vehicle is moving. Always bring the vehicle to a
complete stop before shifting to PARK, and
verify that the transmission gear position indi
-
cator solidly indicates PARK (P) without
blinking. Ensure that the vehicle is completely
stopped, and the PARK position is properly
indicated, before exiting the vehicle.
It is dangerous to shift out of PARK or
NEUTRAL if the engine speed is higher than
idle speed. If your foot is not firmly pressing
the brake pedal, the vehicle 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.
WARNING!
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 running. 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 position, the transmis -
sion is locked in PARK, securing the vehicle
against unwanted movement.
When exiting the vehicle, always make sure
the ignition is in the OFF position, 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 chil -
dren to be in a vehicle unattended is
dangerous for a number of reasons. A child or
others could be seriously or fatally injured.
Children should be warned not to touch the
parking brake, brake pedal or the transmis -
sion 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
position. A child could operate power
windows, other controls, or move the vehicle.

FOUR–WHEEL DRIVE OPERATION
FOUR-POSITION TRANSFER CASE —
I
F EQUIPPED

Four-Wheel Drive Gear Selector

The transfer case provides four positions:
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 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
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 additional traction for
loose, slippery road surfaces only.
N (Neutral)
N (Neutral) — This range disengages both the front
and rear driveshafts from the powertrain. To be
used for flat towing behind another vehicle.
See Recreational Towing for further information
Ú
page 205.
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.
WARNING!
You or others could be injured or killed if you
leave the vehicle unattended with the transfer
case in the N (Neutral) position without first fully
engaging the parking brake. The transfer case N
(Neutral) 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 (or manual transmission
is in gear). The parking brake should always be
applied when the driver is not in the vehicle.4

23_JT_OM_EN_USC_t.book Page 161

162STARTING AND OPERATING
4L
Four-Wheel Drive Low Range — This range provides
low speed four-wheel drive. It maximizes 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 positions 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 driveline
components. For further information on shifting
into 4H or 4L Ú page 162.
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/
disengage 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 1 to 3 mph (2 to 5 km/h),
shift an automatic transmission into NEUTRAL (N), or
press the clutch pedal on a manual transmission.
While the vehicle is coasting at 1 to 3 mph (2 to
5 km/h), shift the transfer case lever firmly to the
desired position. Do not pause with the transfer case
in N (Neutral). Once the shift is completed, place the
automatic transmission into DRIVE or release the
clutch pedal on a manual transmission.

NOTE:Shifting into or out of 4L is possible with the vehicle
completely stopped; however, difficulty 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 1 to
3 mph (2 to 5 km/h). Avoid attempting to engage
or disengage 4L with the vehicle moving faster
than 1 to 3 mph (2 to 5 km/h).
