2023 JEEP GLADIATOR brakes

348IN CASE OF EMERGENCY
In the event it is observed that the temperature
gauge is moving towards or close to the HOT (H)
position, you can reduce the potential for
overheating by taking the appropriate action.
On the highways — slow down.
In city traffic — while stopped, place the trans -
mission in NEUTRAL (N), but do not increase the
engine idle speed while preventing vehicle
motion with the brakes.
If your Air Conditioner (A/C) is on, turn it off. The
A/C system adds heat to the engine cooling
system and turning the A/C off can help remove
this heat.
You can also turn the temperature control to
maximum heat, the mode control to floor and
the blower control to high. This allows the heater
core to act as a supplement to the radiator and
aids in removing heat from the engine cooling
system.
MANUAL PARK RELEASE
In order to move the vehicle in cases where the
transmission will not shift out of Park (P) (such as
a depleted battery), a Manual Park Release is
available. See the following steps to use the Manual Park
Release:

1. Firmly apply the parking brake.

2. Using a small screwdriver or similar tool,
remove the manual park release cover located
in front of the gear selector, to access the
release tether strap.

Manual Park Release Cover

WARNING!
You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator.
If you see or hear steam coming from under the
hood, do not open the hood until the radiator
has had time to cool. Never try to open a cooling
system pressure cap when the radiator or
coolant bottle is hot.
CAUTION!
Driving with a hot cooling system could damage
your vehicle. If the temperature gauge reads “H,
” pull over and stop the vehicle. Idle the vehicle
with the air conditioner turned off until the
pointer drops back into the normal range. If the
pointer remains on the “H” and you hear
continuous chimes, turn the engine off
immediately and call for service.
WARNING!
Always secure your vehicle by fully applying the
parking brake before activating the Manual Park
Release. In addition, you should be seated in the
driver’s seat with your foot firmly on the brake
pedal when activating the Manual Park Release.
Activating the Manual Park Release will allow
your vehicle to roll away if it is not secured by the
parking brake, or by proper connection to a tow
vehicle. Activating the Manual Park Release on
an unsecured vehicle could lead to serious
injury or death for those in or around the vehicle.

(Continued)
BRAKE SYSTEM
In order to ensure brake system performance, all
brake system components should be inspected
periodically. For the proper maintenance intervals
Úpage 354.
Fluid Level Check — Brake Master Cylinder
The fluid level of the master cylinder should be
checked whenever the vehicle is serviced, or
immediately if the Brake System Warning Light is
on. If necessary, add fluid to bring level within the
designated marks on the side of the reservoir of
the brake master cylinder. Be sure to clean the top
of the master cylinder area before removing cap.
With disc brakes, fluid level can be expected to fall
as the brake pads wear. Brake fluid level should be
checked when pads are replaced. If the brake fluid
is abnormally low, check the system for leaks.
For further information Ú page 426.
FRONT/REAR AXLE FLUID
For normal service, periodic fluid level checks are
not required. When the vehicle is serviced for other
reasons the exterior surfaces of the axle assembly
should be inspected. If gear oil leakage is
suspected, inspect the fluid level.
Fluid Level Check
Lubricant should be approximately 1/8 inch
(3 mm) below the bottom edge of the oil fill hole.
NOTE:Make sure that the vehicle is level and supported
by the axles.
Adding Fluid
Add lubricant only at the fill hole and only to the
level specified above.
Selection Of Lubricant
Use only the manufacturer’s recommended fluid
Úpage 426.
WARNING!
Riding the brakes can lead to brake failure and
possibly a collision. Driving with your foot resting
or riding on the brake pedal can result in
abnormally high brake temperatures, excessive
lining wear, and possible brake damage. You
would not have your full braking capacity in an
emergency.
WARNING!
Use only manufacturer recommended brake
fluid Ú page 426. Using the wrong type of
brake fluid can severely damage your brake
system and/or impair its performance. The
proper type of brake fluid for your vehicle is
also identified on the original factory installed
hydraulic master cylinder reservoir.
To avoid contamination from foreign matter or
moisture, use only new brake fluid or fluid that
has been in a tightly closed container. Keep
the master cylinder reservoir cap secured at
all times. Brake fluid in a open container
absorbs moisture from the air resulting in a
lower boiling point. This may cause it to boil
unexpectedly during hard or prolonged
braking, resulting in sudden brake failure. This
could result in a collision.
Overfilling the brake fluid reservoir can result
in spilling brake fluid on hot engine parts,
causing the brake fluid to catch fire. Brake
fluid can also damage painted and vinyl
surfaces, care should be taken to avoid its
contact with these surfaces.
Do not allow petroleum based fluid to contam -
inate the brake fluid. Brake seal components
could be damaged, causing partial or
complete brake failure. This could result in a
collision.
WARNING!

408SERVICING AND MAINTENANCE
When cleaning extremely dirty wheels, including
excessive brake dust, care must be taken in the
selection of tire and wheel cleaning chemicals and
equipment to prevent damage to the wheels.
Mopar® Wheel Treatment or Mopar® Chrome
Cleaner, or their equivalent, is recommended or
select a non-abrasive, non-acidic cleaner for
aluminum or chrome wheels.
NOTE:If you intend parking or storing your vehicle for an
extended period after cleaning the wheels with
wheel cleaner, drive your vehicle and apply the
brakes to remove the water droplets from the
brake components. This activity will remove the
red rust on the brake rotors and prevent vehicle
vibration when braking.
Dark Vapor Chrome, Black Satin Chrome, or Low
Gloss Clear Coat WheelsSNOW TRACTION DEVICES
Use of traction devices require sufficient
tire-to-body clearance. Due to limited clearance,
the following snow traction devices are
recommended. Follow these recommendations to
guard against damage:
Snow traction device must be of proper size for
the tire, as recommended by the snow traction
device manufacturer.
No other tire sizes are recommended for use
with the snow traction device.
Please follow the table below for the recom -
mended tire size, axle and snow traction device:
CAUTION!
Do not use scouring pads, steel wool, a bristle
brush, metal polishes, or oven cleaner. These
products may damage the wheel's protective
finish. Such damage is not covered by the New
Vehicle Limited Warranty. Only car wash soap,
Mopar® Wheel Cleaner or equivalent is
recommended.CAUTION!

If your vehicle is equipped with these specialty
wheels, DO NOT USE wheel cleaners, abrasives,
or polishing compounds. They will permanently
damage this finish and such damage is not
covered by the New Vehicle Limited Warranty.
HAND WASH ONLY USING MILD SOAP AND WATER
WITH A SOFT CLOTH. Used on a regular basis; this
is all that is required to maintain this finish.

TECHNICAL SPECIFICATIONS
VEHICLE IDENTIFICATION NUMBER (VIN)
The VIN is found on the left front corner of the
A-pillar, visible from outside of the vehicle through
the windshield.
Vehicle Identification Number

NOTE:It is illegal to remove or alter the VIN plate.
BRAKE SYSTEM
Your vehicle is equipped with dual hydraulic brake
systems. If either of the two hydraulic systems lose
normal capability, the remaining system will still
function. However, there will be some loss of
overall braking effectiveness. You may notice
increased pedal travel during application, greater
pedal force required to slow or stop, and potential
activation of the Brake Warning Light.
In the event power assist is lost for any reason (i.e.,
repeated brake applications with the engine off)
the brakes will still function. However, the effort
required to brake the vehicle will be much greater
than that required with the power system
operating.
WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to
ensure that the wheel is properly mounted to the
vehicle. Any time a wheel has been removed and
reinstalled on the vehicle, the lug nuts/bolts
should be torqued using a properly calibrated
torque wrench using a six-sided (hex) deep wall
socket.
TORQUE SPECIFICATIONS
**Use only authorized dealer recommended lug nuts/
bolts and clean or remove any dirt or oil before tightening.
Inspect the wheel mounting surface prior to
mounting the tire and remove any corrosion or
loose particles.
