parking brake JEEP GLADIATOR 2023 Owner's Manual

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.

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

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
two-wheel drive position (2H) or four-wheel drive
position (4H AUTO) for normal street and highway
conditions on dry hard surfaced roads.
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.

STARTING AND OPERATING169
If the “SERVICE POWER STEERING”
message and a flashing icon are
displayed on the instrument cluster
screen, it indicates that the vehicle
needs to be taken to an authorized dealer for
service. It is likely the vehicle has lost power
steering assistance Ú page 121.
If the “POWER STEERING HOT” message and an
icon are displayed on the instrument cluster
screen, it indicates that extreme steering
maneuvers may have occurred, which caused an
over temperature condition in the power steering
system. You will lose power steering assistance
momentarily until the over temperature condition
no longer exists. Once driving conditions are safe,
pull over and let vehicle idle for a few moments
until the light turns off Ú page 121.
NOTE:
Even if power steering assistance is no longer
operational, it is still possible to steer the
vehicle. Under these conditions there will be a
substantial increase in steering effort, espe -cially at very low vehicle speeds and during
parking maneuvers.
If the condition persists, see an authorized
dealer for service.
STOP/START SYSTEM — AUTOMATIC
TRANSMISSION (IF EQUIPPED)
The Engine Stop/Start (ESS) function is developed
to reduce fuel consumption. The system will stop
the engine automatically during a vehicle stop if
the required conditions are met. Releasing the
brake pedal or pressing the accelerator pedal will
automatically restart the engine.
ESS vehicles have been upgraded with a
heavy-duty starter, enhanced battery, and other
upgraded engine parts, to handle the additional
engine starts.
NOTE:It is recommended that the Stop/Start system be
disabled during off-road use.
Secondary Battery
Your vehicle may be equipped with a secondary
battery used to power the Stop/Start system and
the 12 Volt vehicle electrical system. The
secondary battery is located behind the wheel well
for the front passenger wheel.

Battery Locations

AUTOSTOP MODE
CAUTION!
Extreme steering maneuvers may cause the
electrically driven pump to reduce or stop power
steering assistance in order to prevent damage
to the system. Normal operation will resume
once the system is allowed to cool.
1 — Primary Battery
2 — Secondary Battery
WARNING!
Vehicles with the Stop/Start system will be
equipped with two batteries. Both the main
and the supplemental batteries must be
disconnected to completely de-energize the
12 Volt electrical system.
Serious injury or death could result if you do
not disconnect both batteries. To learn how to
properly disconnect, see an authorized dealer.

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.

WARNING!
In Fixed Speed Cruise Control mode (ACC not
enabled), the system will not react to vehicles
ahead. In addition, the proximity warning does
not activate and no alarm will sound even if you
are too close to the vehicle ahead since neither
the presence of the vehicle ahead nor the
vehicle-to-vehicle distance is detected. Be sure
to maintain a safe distance between your vehicle
and the vehicle ahead. Always be aware which
mode is selected.

23_JT_OM_EN_USC_t.book Page 178

184STARTING AND OPERATING
STATIONARY OBJECTS AND VEHICLES
ACC does not react to stationary objects or
vehicles. For example, ACC will not react in
situations where the vehicle you are following exits
your lane and the vehicle ahead is stopped in your
lane. It will consider this stopped vehicle a
stationary object as it did not previously detect
movement from it. Always be attentive and ready
to apply the brakes if necessary.

Stationary Object And Stationary Vehicle Example

PARKSENSE FRONT/REAR PARK ASSIST
SYSTEM — IF EQUIPPED
The ParkSense Park Assist system provides visual
and audible indications of the distance between
the rear and/or front fascia/bumper and a
detected obstacle when backing up or moving forward (e.g. during a parking maneuver). For
system limitations and usage precautions, see
Ú
page 188.
ParkSense will retain the last system state
(enabled or disabled) from the last ignition cycle
when the ignition is placed in the ON/RUN position.
ParkSense can be active only when the gear
selector is in REVERSE or DRIVE. If ParkSense is
enabled at one of these gear selector positions,
the system will remain active until the vehicle
speed is increased to approximately 7 mph
(11 km/h) or above. A warning will appear in the
instrument cluster display indicating the vehicle is
above ParkSense operating speed. The system will
become active again if the vehicle speed is
decreased to speeds less than approximately
6 mph (9 km/h).
PARKSENSE SENSORS
The four ParkSense sensors, located in the rear
fascia/bumper, monitor the area behind the
vehicle that is within the sensors’ field of view. The
sensors can detect obstacles from approximately
12 inches (30 cm) up to 79 inches (200 cm) from
the rear fascia/bumper in the horizontal direction,
depending on the location, type and orientation of
the obstacle.
The six ParkSense sensors, located in the front
fascia/bumper, monitor the area in front of the
vehicle that is within the sensors’ field of view. The sensors can detect obstacles from approximately
12 inches (30 cm) up to 47 inches (120 cm) from
the front fascia/bumper in the horizontal direction,
depending on the location, type and orientation of
the obstacle.
PARKSENSE WARNING DISPLAY
The ParkSense Warning screen is located within
the instrument cluster display Ú
page 121. It
provides visual warnings to indicate the distance
between the rear fascia/bumper and/or front
fascia/bumper and the detected obstacle.
PARKSENSE DISPLAY
The warning display will turn on indicating the
system status when the vehicle is in REVERSE or
when the vehicle is in DRIVE and an obstacle has
been detected.
The system will indicate a detected obstacle by
showing a single arc in one or more regions based
on the obstacle’s distance and location relative to
the vehicle.
If an obstacle is detected in the center front region,
the display will show a single solid arc in the center
front region with no chime. As the vehicle moves
closer to the obstacle, the display will show the
single arc moving closer to the vehicle and a fast
sound tone will be heard and will change from fast,
to continuous.

202STARTING AND OPERATING
(Continued)
TRAILER AND TONGUE WEIGHT
Never exceed the maximum tongue weight
stamped on your bumper or trailer hitch.
Weight Distribution

Consider the following items when computing the
weight on the rear axle of the vehicle:
The tongue weight of the trailer
The weight of any other type of cargo or equip -
ment put in or on your vehicle
The weight of the driver and all passengers
NOTE:Remember that everything put into or on the trailer
adds to the load on your vehicle. Also, additional
factory-installed options or dealer-installed options
must be considered as part of the total load on
your vehicle. Refer to the Tire And Loading Infor -
mation Placard for the maximum combined weight
of occupants and cargo for your vehicle.
TOWING REQUIREMENTS
To promote proper break-in of your new vehicle
drivetrain components, the following guidelines
are recommended:
WARNING!
Improper towing can lead to a collision. Follow
these guidelines to make your trailer towing as
safe as possible:
Make certain that the load is secured in the
trailer and that it will not shift during travel.
When trailering cargo that is not fully secured,
dynamic load shifts can occur that may be
difficult for the driver to control. You could lose
control of your vehicle and have a collision.
When hauling cargo, or towing a trailer, do not
overload your vehicle or trailer. Overloading
can cause a loss of control, poor performance,
or damage to brakes, axle, engine, transmis -
sion, steering, suspension, chassis structure,
or tires.
Safety chains must always be used between
your vehicle and trailer. Always connect the
chains to the frame or hook retainers of the
vehicle hitch. Cross the chains under the
trailer tongue and allow enough slack for
turning corners.
Vehicles with trailers should not be parked on
a grade. When parking, apply the parking
brake on the tow vehicle. Put the tow vehicle
transmission in PARK. Always block or "chock"
the trailer wheels.
GCWR must not be exceeded.
Total weight must be distributed between the
tow vehicle and the trailer such that the
following four ratings are not exceeded:
GVWR
GTW
GAWR
Tongue weight rating for the trailer hitch
utilized
CAUTION!

Do not tow a trailer at all during the first
500 miles (805 km) the new vehicle is driven.
The engine, axle or other parts could be
damaged.
Then, during the first 500 miles (805 km) that a
trailer is towed, do not drive over 50 mph
(80 km/h) and do not make starts at full
throttle. This helps the engine and other parts
of the vehicle wear in at the heavier loads.

WARNING!

23_JT_OM_EN_USC_t.book Page 202

206STARTING AND OPERATING
Shifting Into N (Neutral)
Use the following procedure to prepare your
vehicle for recreational towing.

1. Bring the vehicle to a complete stop on level
ground.

2. Press and hold the brake pedal.
3. Shift the automatic transmission into NEUTRAL or press the clutch pedal on a
manual transmission. 4. Turn the engine off.
5. Shift the transfer case lever into N (Neutral).
6. Start the engine.
7. Shift the transmission into DRIVE or REVERSE.
8. Release the brake pedal (and clutch pedal on
manual transmissions) for five seconds and
ensure that there is no vehicle movement.
9. Repeat steps 7 and 8 with automatic transmission in DRIVE or manual transmission
in first gear.
10. Turn the engine off.
11. Firmly apply the parking brake.
12. Shift the transmission into PARK or place manual transmission in gear (NOT in
NEUTRAL).
13. Attach the vehicle to the tow vehicle using a suitable tow bar.
14. Release the parking brake.Automatic transmissions must be placed in
PARK for recreational towing.
Manual transmissions must be placed in gear
(not in Neutral) for recreational towing.
Before recreational towing, perform the proce -
dure outlined under “Shifting Into N (Neutral)”
to be certain that the transfer case is fully in N
(Neutral). Otherwise, internal damage will
result.
Towing this vehicle in violation of the above
requirements can cause severe transmission
and/or transfer case damage. Damage from
improper towing is not covered under the New
Vehicle Limited Warranty.
Do not use a bumper-mounted clamp-on tow
bar on your vehicle. The bumper face bar will
be damaged.
CAUTION!
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.
CAUTION!
It is necessary to follow these steps to be certain
that the transfer case is fully in N (Neutral)
before recreational towing to prevent damage to
internal parts.CAUTION!
Damage to the transmission may occur if the
transmission is shifted into PARK with the
transfer case in N (Neutral) and the engine
running. With the transfer case in N (Neutral)
ensure that the engine is OFF before shifting the
transmission into PARK.
