2023 JEEP GLADIATOR lock

STARTING AND OPERATING159
The following indicators should be used to ensure
that you have properly engaged the transmission
into the PARK position:
When shifting into PARK, push the lock button
on the gear selector and firmly move the gear
selector all the way forward until it stops and is
fully seated.
Look at the transmission gear position display
and verify that it indicates the PARK position (P),
and is not blinking.
With the brake pedal released, verify that the
gear selector will not move out of PARK.
REVERSE (R)
This range is for moving the vehicle backward.
Shift into REVERSE only after the vehicle has come
to a complete stop. NEUTRAL (N)
Use this range when the vehicle is standing for
prolonged periods with the engine running. Apply
the parking brake and shift the transmission into
PARK if you must exit the vehicle.
DRIVE (D)
This range should be used for most city and
highway driving. It provides the smoothest upshifts
and downshifts, and the best fuel economy. The
transmission automatically upshifts through all
forward gears. The DRIVE position should be used
for all normal operating conditions.When frequent transmission shifting occurs (such
as when operating the vehicle under heavy loading
conditions, in hilly terrain, traveling into strong
head winds, or while towing a heavy trailer), use
the AutoStick shift control to select a lower gear
Ú
page 160. Under these conditions, using a lower
gear will improve performance and extend
transmission life by reducing excessive shifting
and heat build-up.
During extremely cold temperatures (-22°F
[-30°C] or below), transmission operation may be
modified depending on engine and transmission
temperature as well as vehicle speed. Normal
operation will resume once the transmission
temperature has risen to a suitable level.
MANUAL (M)
The MANUAL (M, +/-) position (beside the DRIVE
position) enables full manual control of
transmission shifting also known as AutoStick
mode. Toggling the gear selector forward (-) or
rearward (+) while in the MANUAL (AutoStick)
position will manually select the transmission gear,
and will display the current gear in the instrument
cluster Ú page 160.
Transmission Limp Home Mode
Transmission function is monitored electronically
for abnormal conditions. If a condition is detected
that could result in transmission damage,
Transmission Limp Home mode is activated. In this
CAUTION!
Before moving the transmission gear selector
out of PARK, you must start the engine, and
also press the brake pedal. Otherwise,
damage to the gear selector could result.
DO NOT race the engine when shifting from
PARK or NEUTRAL into another gear range, as
this can damage the drivetrain.WARNING!
Do not coast in NEUTRAL and never turn off the
ignition to coast down a hill. These are unsafe
practices that limit your response to changing
traffic or road conditions. You might lose control
of the vehicle and have a collision.
CAUTION!

Towing the vehicle, coasting, or driving for any
other reason with the transmission in NEUTRAL
can cause severe transmission damage.

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).

23_JT_OM_EN_USC_t.book Page 162

164STARTING AND OPERATING
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.
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 164.
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 AUTO OR 4H AUTO TO 2H
Shifting between 2H and 4H AUTO 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.
2H/4H AUTO TO 4H PART TIME OR 4H PART
TIME TO 2H/4H AUTO
Shifting between 2H/4H AUTO to 4H PART TIME
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

increased effort in shifting until the transfer case
fluid warms up. This is normal.
TRAC-LOK REAR AXLE — IF EQUIPPED
The Trac-Lok rear axle provides a constant driving
force to both rear wheels and reduces wheel spin
caused by the loss of traction at one driving wheel.
If traction differs between the two rear wheels, the
differential automatically proportions the usable
torque by providing more torque to the wheel that
has traction.
Trac-Lok is especially helpful during slippery
driving conditions. With both rear wheels on a
slippery surface, a slight application of the
accelerator will supply maximum traction.
AXLE LOCK (TRU-LOK) FRONT AND
R
EAR — IF EQUIPPED
The AXLE LOCK switch is located on the instrument
panel (to the right of the steering column).

Axle Lock Switch Panel

This feature will only activate when the following
conditions are met:
Ignition in ON/RUN position, vehicle in 4L
(Four-Wheel Drive Low Range).
Vehicle speed should be 10 mph (16 km/h) or
less.
Both right and left wheels on axle are at the
same speed.
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!
On vehicles equipped with a limited-slip
differential, never run the engine with one rear
wheel off the ground. The vehicle may drive
through the rear wheel remaining on the ground
and cause you to lose control of your vehicle.

is turned off by the driver, ESC “Full Off” is exited,
or the ignition switch is turned to the OFF position.
NOTE:The indicator lights will flash until the rear axle is
fully locked or unlocked.
The rear Axle Lock system may temporarily
disengage the rear locker under some conditions.
If this occurs, the rear axle will automatically
re-lock as soon as the system allows.
If an Axle Lock request cannot be completed by the
system within 5 seconds due to vehicle operating
conditions not being correct, the request will be
canceled and the driver may need to re-request the
locker to be activated.
ELECTRONIC SWAY BAR DISCONNECT —
I
F EQUIPPED
Your vehicle may be equipped with an electronic
disconnecting stabilizer/sway bar. This system
allows greater front suspension travel in off-road
situations.
WARNING!
This mode is intended for off-highway or off-road
use only and should not be used on any public
roadways.

23_JT_OM_EN_USC_t.book Page 166

STARTING AND OPERATING167
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 disconnect or
connect the sway bar. The Sway Bar Indicator Light
(located in the instrument cluster) will illuminate
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
Úpage 161. The Sway
Bar Indicator Light will flash until the stabilizer/
sway bar has been fully disconnected.
NOTE:The stabilizer/sway bar may be torque locked due
to left and right suspension height differences.
This condition is due to driving surface differences
or vehicle loading. In order for the stabilizer/sway
bar to disconnect/reconnect, the right and left
halves of the bar must be aligned. This alignment
may require that the vehicle be driven onto level
ground or rocked from side to side.
To return to on-road mode, push the SWAY BAR
switch again.WARNING!
Ensure the stabilizer/sway bar is reconnected
before driving on hard surfaced roads or at
speeds above 18 mph (29 km/h); a discon -
nected stabilizer/sway bar may contribute to the
loss of vehicle control, which could result in seri -
ous injury. Under certain circumstances, the
front stabilizer/sway bar enhances vehicle sta -
bility and assists with vehicle control. The sys-
tem 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 flash -
ing or solid Sway Bar Indicator Light. Once vehi -
cle speed is reduced below 14 mph (22 km/h),
the system will once again attempt to return to
off-road mode.
WARNING!
If the stabilizer/sway bar will not return to
on-road mode, the Sway Bar Indicator Light will
flash in the instrument cluster and vehicle
stability may be reduced. Do not attempt to drive
the vehicle over 18 mph (29 km/h). Driving
faster than 18 mph (29 km/h) with a
disconnected stabilizer/sway bar may contribute
to the loss of vehicle control, which could result
in serious injury.
