2023 JEEP GLADIATOR tire pressure

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
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 PART TIME/4H AUTO TO 4L OR 4L TO 4H
PART TIME/4H AUTO
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

STARTING AND OPERATING175
To Accelerate For Passing
While the Cruise Control is set, press the
accelerator to pass as you would normally. When
the pedal is released, the vehicle will return to the
set speed.
USING CRUISE CONTROL ON HILLS
The transmission may downshift on hills to
maintain the vehicle set speed.
The Cruise Control system maintains speed up and
down hills. A slight speed change on moderate hills
is normal. On steep hills, a greater speed loss or
gain may occur so it may be preferable to drive
without Cruise Control.
To Resume Speed
To resume a previously set speed, push the RES
button and release. Resume can be used at any
speed above 20 mph (32 km/h).
To Deactivate
A soft tap on the brake pedal, pushing the CANC
(cancel) button, or normal brake pressure while
slowing the vehicle will deactivate the Cruise
Control without erasing the set speed from
memory.
The following conditions will also deactivate the
Cruise Control without erasing the set speed from
memory:
Vehicle parking brake is applied
Stability event occurs
Gear selector is moved out of DRIVE
Engine overspeed occurs
Clutch pedal is pressed (manual transmission
only)
Vehicle is operating at a low RPM (manual trans -
mission only)
Pushing the on/off button or placing the ignition in
the OFF position, erases the set speed from
memory.
ADAPTIVE CRUISE CONTROL (ACC)
Adaptive Cruise Control (ACC) increases the driving
convenience provided by Cruise Control while
traveling on highways and major roadways.
However, it is not a safety system and not designed
to prevent collisions. The Cruise Control function
performs differently if your vehicle is not equipped
with ACC Ú page 173.
ACC will allow you to keep Cruise Control engaged
in light to moderate traffic conditions without the
constant need to reset your speed. ACC utilizes a
radar sensor and a forward-facing camera
designed to detect a vehicle directly ahead of you
to maintain a set speed.
NOTE:
If the ACC sensor detects a vehicle ahead, ACC
will apply limited braking or accelerate (not to
exceed the original set speed) automatically to
maintain a preset following distance, while
matching the speed of the vehicle ahead.
Any chassis/suspension or tire size modifica -
tions to the vehicle will affect the performance
of the Adaptive Cruise Control and Forward Colli -
sion Warning system.
Fixed Speed Cruise Control (ACC not enabled)
will not detect vehicles directly ahead of you.
Always be aware of the feature selected
Ú page 432.
WARNING!
Cruise Control can be dangerous where the
system cannot maintain a constant speed. Your
vehicle could go too fast for the conditions, and
you could lose control and have an accident. Do
not use Cruise Control in heavy traffic or on
roads that are winding, icy, snow-covered or
slippery.

196STARTING AND OPERATING
This label contains the month and year of
manufacture, Gross Vehicle Weight Rating
(GVWR), front and rear Gross Axle Weight Rating
(GAWR), and Vehicle Identification Number (VIN). A
Month-Day-Hour (MDH) number is included on this
label and indicates the Month, Day and Hour of
manufacture. The bar code that appears on the
bottom of the label is your VIN.
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total permissible weight of your
vehicle including driver, passengers, vehicle,
options and cargo. The label also specifies
maximum capacities of front and rear Gross Axle
Weight Rating (GAWR). Total load must be limited
so GVWR on front and rear GAWR are not
exceeded.
Payload
The payload of a vehicle is defined as the allowable
load weight a truck can carry, including the weight
of the driver, all passengers, options and cargo.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum permissible load on the
front and rear axles. The load must be distributed
in the cargo area so that the GAWR of each axle is
not exceeded.
Each axle GAWR is determined by the components
in the system with the lowest load carrying capacity
(axle, springs, tires or wheels). Heavier axles or
suspension components sometimes specified by purchasers for increased durability does not
necessarily increase the vehicle's GVWR.
Tire Size
The tire size on the Vehicle Certification Label
represents the actual tire size on your vehicle.
Replacement tires must be equal to the load
capacity of this tire size.
Rim Size
This is the rim size that is appropriate for the tire
size listed.
Inflation Pressure
This is the cold tire inflation pressure for your
vehicle for all loading conditions up to full GAWR.
Curb Weight
The curb weight of a vehicle is defined as the total
weight of the vehicle with all fluids, including
vehicle fuel, at full capacity conditions, and with no
occupants or cargo loaded into the vehicle. The
front and rear curb weight values are determined
by weighing your vehicle on a commercial scale
before any occupants or cargo are added.
Loading
The actual total weight and the weight of the front
and rear of your vehicle at the ground can best be
determined by weighing it when it is loaded and
ready for operation.
The entire vehicle should first be weighed on a
commercial scale to ensure that the GVWR has not
been exceeded. The weight on the front and rear of
the vehicle should then be determined separately
to be sure that the load is properly distributed over
the front and rear axle. Weighing the vehicle may
show that the GAWR of either the front or rear axles
has been exceeded but the total load is within the
specified GVWR. If so, weight must be shifted from
front to rear or rear to front as appropriate until the
specified weight limitations are met. Store the
heavier items down low and be sure that the
weight is distributed equally. Stow all loose items
securely before driving.
Improper weight distributions can have an adverse
effect on the way your vehicle steers and handles
and the way the brakes operate.
WARNING!
Do not load your vehicle any heavier than the
GVWR or the maximum front and rear GAWR. If
you do, parts on your vehicle can break, or it can
change the way your vehicle handles. This could
cause you to lose control. Overloading can
shorten the life of your vehicle.

STARTING AND OPERATING203
Towing Requirements — Tires
Proper tire inflation pressures are essential to
the safe and satisfactory operation of your
vehicle.
Check the trailer tires for proper tire inflation
pressures before trailer usage.
Check for signs of tire wear or visible tire
damage before towing a trailer.
Replacing tires with a higher load carrying
capacity will not increase the vehicle's GVWR
and GAWR limits.
For further information Úpage 395.
Towing Requirements — Trailer Brakes
Do not interconnect the hydraulic brake system
or vacuum system of your vehicle with that of
the trailer. This could cause inadequate braking
and possible personal injury.
An electronically actuated trailer brake
controller is required when towing a trailer with
electronically actuated brakes. When towing a
trailer equipped with a hydraulic surge actuated
brake system, an electronic brake controller is
not required.
NOTE:This vehicle has an aftermarket brake controller
connector under the dash to the left of the brake
pedal. This will be a four pin connector and will be
gray in color.
Trailer brakes are recommended for trailers
over 1,000 lb (453 kg) and required for trailers
in excess of 2,000 lb (907 kg).Towing Requirements — Trailer Lights And
Wiring
Whenever you pull a trailer, regardless of the trailer
size, stop lights and turn signals on the trailer are
required for motoring safety.
The Trailer Tow Package may include a four- and
seven-pin wiring harness. Use a factory approved
trailer harness and connector.
NOTE:Do not cut or splice wiring into the vehicle’s wiring
harness.
The electrical connections are all complete to the
vehicle but you must mate the harness to a trailer
connector. Refer to the following illustrations.
NOTE:
Disconnect the trailer wiring connector from the
vehicle (or any other device plugged into
vehicle’s electrical connectors) before
launching a boat into water.
Be sure to reconnect once clear from water
area.
WARNING!
Do not connect trailer brakes to your vehicle's
hydraulic brake lines. It can overload your
brake system and cause it to fail. You might
not have brakes when you need them and
could have an accident.
Towing any trailer will increase your stopping
distance. When towing, you should allow for
additional space between your vehicle and the
vehicle in front of you. Failure to do so could
result in an accident.
CAUTION!
If the trailer weighs more than 1,000 lb (453 kg)
loaded, it should have its own brakes and they
should be of adequate capacity. Failure to do
this could lead to accelerated brake lining wear,
higher brake pedal effort, and longer stopping
distances.

STARTING AND OPERATING209
additional low speed pulling power is needed.
Vehicle speeds in excess of 25 mph (40 km/h)
should be avoided when in 4L range.
Simultaneous Brake And Throttle
Operation
Many off-road driving conditions require the
simultaneous use of the brake and throttle
(two-footed driving). When climbing rocks, logs, or
other stepped objects, using light brake pressure
with light throttle will keep the vehicle from jerking
or lurching. This technique is also used when you
need to stop and restart a vehicle on a steep
incline.
Driving In Snow, Mud And Sand
SNOW
In heavy snow or for additional control and traction
at slower speeds, shift the transmission into a low
gear and the transfer case into 4L if necessary. Do
not shift to a lower gear than necessary to maintain
headway. Over-revving the engine can spin the
wheels and traction will be lost. If you start to slow
to a stop, try turning your steering wheel no more than a quarter turn quickly back and forth, while
still applying throttle. This will allow the tires to get
fresh traction and help maintain your momentum.
MUD
Deep mud creates a great deal of suction around
the tires and is very difficult to get through. You
should use DRIVE, with the transfer case in the 4L
position to maintain your momentum. If you start to
slow to a stop, try turning your steering wheel no
more than a quarter turn quickly back and forth for
additional traction. Mud holes pose an increased
threat of vehicle damage and getting stuck. They
are normally full of debris from previous vehicles
getting stuck. As a good practice before entering
any mud hole, get out and determine how deep it
is, if there are any hidden obstacles and if the
vehicle can be safely recovered if stuck.
SAND
Soft sand is very difficult to travel through with full
tire pressure. When crossing soft, sandy spots in a
trail, maintain your vehicle's momentum and do
not stop. The key to driving in soft sand is using the
appropriate tire pressure, accelerating slowly, avoiding abrupt maneuvers and maintaining the
vehicle's momentum. If you are going to be driving
on large soft sandy areas or dunes, reduce your
tire pressure to a minimum of 15 psi (103 kPa) to
allow for a greater tire surface area. Reduced tire
pressure will drastically improve your traction and
handling while driving on the soft sand, but you
must return the tires to normal air pressure before
driving on pavement or other hard surfaces. Be
sure you have a way to reinflate the tires prior to
reducing the pressure.
Crossing Obstacles (Rocks And Other High
Points)
While driving off-road, you will encounter many
types of terrain. These varying types of terrain bring
different types of obstacles. Before proceeding,
review the path ahead to determine the correct
approach and your ability to safely recover the
vehicle if something goes wrong. Keeping a firm
grip on the steering wheel, bring the vehicle to a
complete stop and then inch the vehicle forward
CAUTION!
Do not use 4L range when operating the vehicle
on dry pavement. Driveline hardware damage
can result.
CAUTION!
On icy or slippery roads, do not downshift at high
engine RPM or vehicle speeds, because engine
braking may cause skidding and loss of control.
CAUTION!
Reduced tire pressures may cause tire
unseating and total loss of air pressure. To
reduce the risk of tire unseating, while at a
reduced tire pressure, reduce your speed and
avoid sharp turns or abrupt maneuvers.

210STARTING AND OPERATING
until it makes contact with the object. Apply the
throttle lightly while holding a light brake pressure
and ease the vehicle up and over the object.
USING A SPOTTER
There are many times where it is hard to see the
obstacle or determine the correct path.
Determining the correct path can be extremely
difficult when you are confronting many obstacles.
In these cases have someone guide you over,
through, or around the obstacle. Have the person
stand a safe distance in front of you where they
can see the obstacle, watch your tires and
undercarriage, and guide you through.
CROSSING LARGE ROCKS
When approaching large rocks, choose a path
which ensures you drive over the largest of them
with your tires. This will lift your undercarriage over
the obstacle. The tread of the tire is tougher and
thicker than the side wall and is designed to take
the abuse. Always look ahead and make every
effort to cross the large rocks with your tires.
CROSSING A RAVINE, GULLY, DITCH,
WASHOUT OR RUT
When crossing a ravine, gully, ditch, washout or a
large rut, the angled approach is the key to
maintaining your vehicle's mobility. Approach
these obstacles at a 45-degree angle and let each
tire go through the obstacle independently. You
need to use caution when crossing large obstacles
with steep sides. Do not attempt to cross any large
obstacle with steep sides at an angle great enough
to put the vehicle at risk of a rollover. If you get
caught in a rut, dig a small trench to the right or left
at a 45-degree angle ahead of the front tires. Use
the removed dirt to fill the rut ahead of the turnout
you just created. You should now be able to drive
out following the trench you just created at a
45-degree angle.
CROSSING LOGS
To cross a log, approach it at a slight angle
(approximately 10 to 15 degrees). This allows one
front tire to be on top of the log while the other just
starts to climb the log. While climbing the log,
modulate your brake and accelerator to avoid
spinning the log out from under your tires. Then
ease the vehicle off the log using your brakes.
GETTING HIGH-CENTERED
If you get hung up or high-centered on an object,
get out of the vehicle and try to determine what the
vehicle is hung up on, where it is contacting the
underbody and what is the best direction to
recover the vehicle. Depending on what you are in
contact with, jack the vehicle up and place a few
rocks under the tires so the weight is off of the high
point when you let the vehicle down. You can also
try rocking the vehicle or winching the vehicle off
the object.
WARNING!
Crossing obstacles can cause abrupt steering
system loading which could cause you to lose
control of your vehicle.
CAUTION!
Never attempt to straddle a rock that is large
enough to strike your axles or undercarriage.
Never attempt to drive over a rock which is
large enough to contact the door sills.
WARNING!
There is an increased risk of rollover when
crossing an obstacle, at any angle, with steep
sides.
CAUTION!
Do not attempt to cross a log with a greater
diameter than the running ground clearance or
the vehicle will become high-centered.
CAUTION!
Winching or rocking the vehicle off hard objects
increases the risk of underbody damage.

SAFETY283
ESC Activation/Malfunction Indicator Light
And ESC OFF Indicator Light
The ESC Activation/Malfunction Indicator
Light in the instrument cluster will come
on when the ignition is placed in the ON/
RUN mode. It should go out with the
engine running. If the ESC Activation/Malfunction
Indicator Light comes on continuously with the
engine running, a malfunction has been detected
in the ESC system. If this light remains on after
several ignition cycles, and the vehicle has been
driven several miles (kilometers) at speeds greater
than 30 mph (48 km/h), see an authorized dealer
as soon as possible to have the problem
diagnosed and corrected.
The ESC Activation/Malfunction Indicator Light
starts to flash as soon as the tires lose traction and
the ESC system becomes active. The ESC
Activation/Malfunction Indicator Light also flashes
when the Traction Control System (TCS) is active. If
the ESC Activation/Malfunction Indicator Light
begins to flash during acceleration, ease up on the
accelerator and apply as little throttle as possible.
Be sure to adapt your speed and driving to the
prevailing road conditions.
NOTE:
The ESC Activation/Malfunction Indicator Light
and the ESC OFF Indicator Light come on
momentarily each time the ignition is placed in
the ON/RUN mode.
Each time the ignition is placed in the ON/RUN
position, the ESC system will be on even if it was
turned off previously.
The ESC system will make buzzing or clicking
sounds when it is active. This is normal; the
sounds will stop when ESC becomes inactive
following the maneuver that caused the ESC
activation.
The ESC OFF Indicator Light indicates
that the Electronic Stability Control (ESC)
is in a reduced mode.
Hill Start Assist (HSA)
The HSA system is designed to mitigate roll back
from a complete stop while on an incline. If the
driver releases the brake while stopped on an
incline, HSA will continue to hold the brake
pressure for a short period. If the driver does not
apply the throttle before this time expires, the
system will release brake pressure and the vehicle
will roll down the hill as normal.
The following conditions must be met in order for
HSA to activate:
The feature must be enabled.
The vehicle must be stopped.
The parking brake must be off.
The driver door must be closed. (If the doors are
attached, then the door must be closed. If the doors are detached then the driver's seat belt
must be buckled.)
The vehicle must be on a sufficient grade.
The gear selection must match vehicle uphill
direction (i.e., vehicle facing uphill is in forward
gear; vehicle backing uphill is in REVERSE gear).
HSA will work in REVERSE gear and all forward
gears. The system will not activate if the trans
-
mission is in PARK or NEUTRAL. For vehicles
equipped with a manual transmission, if the
clutch is pressed, HSA will remain active.
WARNING!
There may be situations where the Hill Start
Assist (HSA) will not activate and slight rolling
may occur, such as on minor hills or with a
loaded vehicle, or while pulling a trailer. HSA is
not a substitute for active driving involvement. It
is always the driver’s responsibility to be
attentive to distance to other vehicles, people,
and objects, and most importantly brake
operation to ensure safe operation of the vehicle
under all road conditions. Your complete
attention is always required while driving to
maintain safe control of your vehicle. Failure to
follow these warnings can result in a collision or
serious personal injury.
