2023 JEEP WAGONEER four wheel drive

STARTING AND OPERATING195
If you stall or begin to lose forward motion while climbing
a steep hill, allow your vehicle to come to a stop and
immediately apply the brakes. Restart the engine, and
shift into REVERSE (R). Back slowly down the hill, allowing
the compression braking of the engine to help regulate
your speed. If the brakes are required to control vehicle
speed, apply them lightly and avoid locking or skidding the
tires.
Remember, never drive diagonally across a hill. Always
drive straight up or down.
If the wheels start to slip as you approach the crest of a
hill, ease off the accelerator and maintain forward motion
by turning the front wheels slowly. This may provide a fresh
“bite” into the surface and will usually provide traction to
complete the climb.Traction Downhill
When descending mountains or hills, use Hill Descent
Control or Selec-Speed Control to avoid repeated heavy
braking.
If not equipped with Hill Descent Control or Selec-Speed
Control use the following procedure:
Shift the transmission into a low gear, and the transfer
case into 4WD LOW range. Let the vehicle go slowly down
the hill with all four wheels turning against engine
compression drag. This will permit you to control the
vehicle speed and direction.
When descending mountains or hills, repeated braking
can cause brake fade with loss of braking control. Avoid
repeated heavy braking by downshifting the transmission
whenever possible.
After Driving Off-Road
Off-road operation puts more stress on your vehicle than
does most on-road driving. After going off-road, it is always
a good idea to check for damage. That way you can get any
problems taken care of right away and have your vehicle
ready when you need it.
Completely inspect the underbody of your vehicle.
Check tires, body structure, steering, suspension, and
exhaust system for damage.
 Inspect the radiator for mud and debris and clean as
required. 
Check threaded fasteners for looseness, particularly
on the chassis, drivetrain components, steering, and
suspension. Retighten them, if required, and torque to
the values specified in the Service Manual.
 Check for accumulations of plants or brush. These
things could be a fire hazard. They might hide damage
to fuel lines, brake hoses, axle pinion seals, and
propeller shafts.
 After extended operation in mud, sand, water, or
similar dirty conditions, have the radiator, fan, brake
rotors, wheels, brake linings, and axle yokes inspected
and cleaned as soon as possible.
 If you experience unusual vibration after driving in
mud, slush or similar conditions, check the wheels for
impacted material. Impacted material can cause a
wheel imbalance and freeing the wheels of it will
correct the situation.
WARNING!
If the engine stalls, you lose forward motion, or cannot
make it to the top of a steep hill or grade, never attempt
to turn around. To do so may result in tipping and rolling
the vehicle. Always back carefully straight down a hill in
REVERSE gear. Never back down a hill in NEUTRAL
using only the brake.
WARNING!
Abrasive material in any part of the brakes may cause
excessive wear or unpredictable braking. You might not
have full braking power when you need it to prevent a
collision. If you have been operating your vehicle in dirty
conditions, get your brakes checked and cleaned as
necessary.

SAFETY
SAFETY FEATURES
ANTI-LOCK BRAKE SYSTEM (ABS)
The ABS provides increased vehicle stability and brake
performance under most braking conditions. The system
automatically prevents wheel lock and enhances vehicle
control during braking.
The ABS performs a self-check cycle to ensure that the
ABS is working properly each time the vehicle is started
and driven. During this self-check, you may hear a slight
clicking sound as well as some related motor noises.
The ABS is activated during braking when the system
detects one or more wheels are beginning to lock. Road
conditions such as ice, snow, gravel, bumps, railroad
tracks, loose debris, or panic stops may increase the
likelihood of ABS activation(s).
You also may experience the following normal
characteristics when the ABS activates:
ABS motor noise or clicking sounds (you may continue
to hear for a short time after the stop).
 Brake pedal pulsations.
 A slight drop of the brake pedal at the end of the stop. The ABS is designed to function with the Original
Equipment Manufacturer (OEM) tires. Modification may
result in degraded ABS performance.
Anti-Lock Brake System (ABS) Warning
Light
The yellow ABS Warning Light will turn on when the ignition
is placed in the ON/RUN mode and may stay on for as long
as four seconds.
If the ABS Warning Light remains on or comes on while
driving, it indicates that the anti-lock portion of the brake
system is not functioning and that service is required.
However, the conventional brake system will continue to
operate normally if the ABS Warning Light is on.
If the ABS Warning Light is on, the brake system should be
serviced as soon as possible to restore the benefits of
Anti-Lock Brakes. If the ABS Warning Light does not come
on when the ignition is placed in the ON/RUN mode, have
the light repaired as soon as possible.
WARNING!

The ABS contains sophisticated electronic equip -
ment that may be susceptible to interference caused
by improperly installed or high output radio transmit -
ting equipment. This interference can cause possible
loss of anti-lock braking capability. Installation of
such equipment should be performed by qualified
professionals.
 Pumping of the Anti-Lock Brakes will diminish their
effectiveness and may lead to a collision. Pumping
makes the stopping distance longer. Just press firmly
on your brake pedal when you need to slow down or
stop.
 The ABS cannot prevent the natural laws of physics
from acting on the vehicle, nor can it increase
braking or steering efficiency beyond that afforded
by the condition of the vehicle brakes and tires or the
traction afforded.
 The ABS cannot prevent collisions, including those
resulting from excessive speed in turns, following
another vehicle too closely, or hydroplaning.
The capabilities of an ABS equipped vehicle must
never be exploited in a reckless or dangerous
manner that could jeopardize the user’s safety or the
safety of others.

ELECTRONIC BRAKE CONTROL (EBC)
S
YSTEM
Your vehicle is equipped with an advanced EBC system.
This system includes the Anti-Lock Brake System (ABS),
Brake Assist System (BAS), Electronic Brake Force
Distribution (EBD), Electronic Stability Control (ESC),
Electronic Roll Mitigation (ERM), Hill Start Assist (HSA),
Intersection Collision Assist (ICA), and Traction Control
System (TCS). These systems work together to enhance
both vehicle stability and control in various driving
conditions.
Your vehicle may also be equipped with Dynamic Steering
Torque (DST), Rain Brake Support (RBS), Ready Alert
Braking (RAB), and Trailer Sway Control (TSC).
Brake Assist System (BAS)
The BAS is designed to optimize the vehicle’s braking
capability during emergency braking maneuvers. The
system detects an emergency braking situation by sensing
the rate and amount of brake application and then applies
optimum pressure to the brakes. This can help reduce
braking distances. The BAS complements the Anti-Lock
Brake System (ABS). Applying the brakes very quickly
results in the best BAS assistance. To receive the benefit
of the system, you must apply continuous braking
pressure during the stopping sequence (do not “pump”
the brakes). Do not reduce brake pedal pressure unless
braking is no longer desired. Once the brake pedal is
released, the BAS is deactivated.
Brake System Warning Light
The red Brake System Warning Light will turn on when the
ignition is placed in the ON/RUN mode and may stay on for
as long as four seconds.
If the Brake System Warning Light remains on or comes on
while driving, it indicates that the brake system is not
functioning properly and that immediate service is
required. If the Brake System Warning Light does not
come on when the ignition is placed in the ON/RUN mode,
have the light repaired as soon as possible.
Electronic Brake Force Distribution (EBD)
EBD manages the distribution of the braking torque
between the front and rear axles by limiting braking
pressure to the rear axle. This is done to prevent
overslip of the rear wheels to avoid vehicle instability, and
to prevent the rear axle from entering ABS before the
front axle.
Electronic Roll Mitigation (ERM)
ERM anticipates the potential for wheel lift by monitoring
the driver’s steering wheel input and the speed of the
vehicle. When ERM determines that the rate of change of
the steering wheel angle and vehicle’s speed are
sufficient to potentially cause wheel lift, it then applies the
appropriate brake and may also reduce engine power to
lessen the chance that wheel lift will occur. ERM can only
reduce the chance of wheel lift occurring during severe or
evasive driving maneuvers; it cannot prevent wheel lift
due to other factors, such as road conditions, leaving the
roadway, or striking objects or other vehicles.
NOTE:
ERM is disabled any time the ESC is in “Full Off” mode (if
equipped). See
Úpage 242 for a complete explanation of
the available ESC modes.
WARNING!
The Brake Assist System (BAS) cannot prevent the
natural laws of physics from acting on the vehicle, nor
can it increase the traction afforded by prevailing road
conditions. BAS cannot prevent collisions, including
those resulting from excessive speed in turns, driving
on very slippery surfaces, or hydroplaning. The
capabilities of a BAS-equipped vehicle must never be
exploited in a reckless or dangerous manner, which
could jeopardize the user's safety or the safety of
others.
WARNING!
Many factors, such as vehicle loading, road conditions
and driving conditions, influence the chance that wheel
lift or rollover may occur. ERM cannot prevent all wheel
lift or rollovers, especially those that involve leaving the
roadway or striking objects or other vehicles. The
capabilities of an ERM-equipped vehicle must never be
exploited in a reckless or dangerous manner which
could jeopardize the user's safety or the safety of
others.

254SAFETY
The Tire Pressure Monitoring System (TPMS) uses wireless
technology with wheel rim-mounted electronic sensors to
monitor tire pressure levels. Sensors, mounted to each
wheel as part of the valve stem, transmit tire pressure
readings to the receiver module.

Tire Pressure Monitoring System Display

NOTE:It is particularly important for you to regularly check the
tire pressure in all of your tires and to maintain the proper
pressure.
The Tire Pressure Monitoring System (TPMS) consists of
the following components:
Receiver module
 Four Tire Pressure Monitoring System sensors
 Various Tire Pressure Monitoring System messages,
which display in the instrument cluster, and a graphic
displaying tire pressures
 TPMS Warning Light
Tire Pressure Monitoring System Low
Pressure Warnings
The TPMS Warning Light will illuminate in the
instrument cluster, and an audible chime will
be activated, when one or more of the four
active road tire pressures are low. In addition,
the instrument cluster will display an "Inflate to XX"
message and a graphic display of the pressure value(s)
with the low tire(s) in a different color
Úpage 99.
NOTE:Your system can be set to display pressure units in
PSI, BAR, or kPa.

Low Tire Pressure Monitoring System Display

Should a low tire condition occur on any of the four active
road tire(s), you should stop as soon as possible, and
inflate the low tire(s) that is in a different color on the
graphic display to the vehicle’s recommended cold tire
pressure displayed in the “Inflate to XX” message.
NOTE:When filling warm tires, the tire pressure may need to be
increased up to an additional 4 psi (28 kPa) above the
recommended cold placard pressure in order to turn the
TPMS Warning Light off.
The system will automatically update, the graphic display
of the pressure value(s) will return to its original color and
the TPMS Warning Light will extinguish once the updated
tire pressure(s) have been received. The vehicle may need
to be driven for up to 20 minutes above 15 mph (24 km/h) to receive this information.
Service TPMS Warning
The Tire Pressure Monitoring System Warning Light will
flash on and off for 75 seconds, and remain on solid when
a system fault is detected. The system fault will also sound
a chime. The instrument cluster display will display a
“SERVICE TPM SYSTEM” message for a minimum of five
seconds. This message is then followed by a graphic
display, with “--“ in place of the pressure value(s),
indicating which Tire Pressure Monitoring System
sensor(s) is not being received.
If the ignition switch is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault no
longer exists, the Tire Pressure Monitoring System
Warning Light will no longer flash, the "SERVICE TPM
SYSTEM" message will not be present, and a pressure
value will be displayed instead of dashes. A system fault
can occur by any of the following:
 Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the
TPMS sensors.

23_WS_OM_EN_USC_t.book Page 254

SAFETY255
Lots of snow or ice around the wheels or wheel
housings.
 Using tire chains on the vehicle.
 Using wheels/tires not equipped with TPMS sensors.
NOTE:There is no Tire Pressure Monitoring System sensor in the
spare tire. The TPMS will not be able to monitor the tire
pressure. If you install the spare tire in place of a road tire
that has a pressure below the low-pressure warning limit,
upon the next ignition switch cycle, the Tire Pressure Moni -
toring System Warning Light will remain on, a chime will
sound, and the instrument cluster display will still display
a pressure value in the different color graphic display and
an “Inflate to XX” message will be displayed. After driving
the vehicle for up to 20 minutes above 15 mph (24 km/h),
the Tire Pressure Monitoring System Warning Light will
flash on and off for 75 seconds and then remain on solid.
In addition, the instrument cluster display will display a
“SERVICE TPM SYSTEM" message for five seconds and
then display dashes (--) in place of the pressure value. For
each subsequent ignition switch cycle, a chime will sound,
the Tire Pressure Monitoring System Warning Light will
flash on and off for 75 seconds and then remain on solid,
and the instrument cluster display will display a "SERVICE
TPM SYSTEM" message for five seconds and then display
dashes (--) in place of the pressure value. Once you repair
or replace the original road tire, and reinstall it on the
vehicle in place of the spare tire, the TPMS will update
automatically.
In addition, the Tire Pressure Monitoring System Warning
Light will turn off and the graphic in the instrument cluster
display will display a new pressure value instead of
dashes (--), as long as no tire pressure is below the low-pressure warning limit in any of the four active road
tires. The vehicle may need to be driven for up to
20 minutes above 15 mph (24 km/h) in order for the
TPMS to receive this information.TPMS Deactivation — If Equipped
The Tire Pressure Monitoring System (TPMS) can be
deactivated if replacing all four wheel and tire assemblies
(road tires) with wheel and tire assemblies that do not
have TPMS sensors, such as when installing winter wheel
and tire assemblies on your vehicle.
To deactivate the TPMS, first, replace all four wheel and
tire assemblies (road tires) with tires not equipped with
Tire Pressure Monitoring System sensors. Then, drive the
vehicle for 20 minutes above 15 mph (24 km/h). The TPMS will chime, the TPMS Warning Light will flash on and
off for 75 seconds and then remain on. The instrument
cluster will display the “SERVICE TPM SYSTEM” message
and then display dashes (--) in place of the pressure
values.
Beginning with the next ignition cycle, the TPMS will no
longer chime or display the “SERVICE TPM SYSTEM”
message in the instrument cluster but dashes (--) will
remain in place of the pressure values.
To reactivate the TPMS, replace all four wheel and tire
assemblies (road tires) with tires equipped with TPMS
sensors. Then, drive the vehicle for up to 20 minutes
above 15 mph (24 km/h). The TPMS will chime, the TPMS
Warning Light will flash on and off for 75 seconds and then
turn off. The instrument cluster will display the “SERVICE
TPM SYSTEM” message and then display pressure values
in place of the dashes. On the next ignition cycle the
"SERVICE TPM SYSTEM" message will no longer be
displayed as long as no system fault exists.
Tire Fill Alert
This feature notifies the user when the placard tire
pressure is attained while inflating or deflating the tire.
The customer may choose to disable or enable the Tire Fill
Alert feature in the apps menu of the Uconnect system.
NOTE:
 The Tire Fill Alert system will only support inflating or
deflating one tire at a time. The user is required to wait
until the hazard lights STOP flashing or 26-30 seconds
after the desired pressure is achieved in one wheel
before switching to another.
 The Tire Fill Alert feature cannot be entered if an
existing TPMS fault is set to “active” or if the system is
in deactivation mode (if equipped).
The system will be activated when the system detects an
increase in tire pressure while filling the tire. The ignition
must be in the ON/RUN mode with the transmission in
PARK.
NOTE:It is not required to have the engine running to enter Tire
Fill Alert mode.
The hazard lights will come on to confirm the vehicle is in
Tire Fill Alert mode. If the hazard lights do not come on
while inflating the tire, the Tire Pressure Monitoring
System sensor may be in an inoperative position,
preventing the TPMS sensor signal from being received. In
this case, the vehicle may need to be moved slightly
forward or backward.

Air Bag Warning Light
The Occupant Restraint Controller (ORC)
monitors the readiness of the electronic parts
of the air bag system whenever the ignition
switch is in the START or ON/RUN position.
If the ignition switch is in the OFF position, the air bag
system is not on and the air bags will not inflate.
The ORC contains a backup power supply system that may
deploy the air bag system even if the battery loses power
or it becomes disconnected prior to deployment.
The ORC turns on the Air Bag Warning Light in the
instrument panel for approximately four to eight seconds
for a self-check when the ignition switch is first in the ON/
RUN position. After the self-check, the Air Bag Warning
Light will turn off. If the ORC detects a malfunction in any
part of the system, it turns on the Air Bag Warning Light,
either momentarily or continuously. A single chime will
sound to alert you if the light comes on again after initial
startup.
The ORC also includes diagnostics that will illuminate the
instrument panel Air Bag Warning Light if a malfunction is
detected that could affect the air bag system. The
diagnostics also record the nature of the malfunction.
While the air bag system is designed to be maintenance
free, if any of the following occurs, have an authorized
dealer service the air bag system immediately.
 The Air Bag Warning Light does not come on during the
four to eight seconds when the ignition switch is first in
the ON/RUN position.
 The Air Bag Warning Light remains on after the four to
eight-second interval.
 The Air Bag Warning Light comes on intermittently or
remains on while driving.
NOTE:If the speedometer, tachometer, or any engine related
gauges are not working, the Occupant Restraint Controller
(ORC) may also be disabled. In this condition the air bags
may not be ready to inflate for your protection. Have an
authorized dealer service the air bag system immediately.
Redundant Air Bag Warning Light
If a fault with the Air Bag Warning Light is
detected, which could affect the Supplemental
Restraint System (SRS), the Redundant Air Bag
Warning Light will illuminate on the instrument
panel. The Redundant Air Bag Warning Light will stay on
until the fault is cleared. In addition, a single chime will
sound to alert you that the Redundant Air Bag Warning
Light has come on and a fault has been detected. If the
Redundant Air Bag Warning Light comes on intermittently
or remains on while driving have an authorized dealer
service the vehicle immediately
Úpage 108.
Front Air Bags
This vehicle has front air bags and lap/shoulder belts for
both the driver and front passenger. The front air bags are
a supplement to the seat belt restraint systems. The driver
front air bag is mounted in the center of the steering
wheel. The passenger front air bag is mounted in the
instrument panel, above the glove compartment. The
words “SRS AIRBAG” or “AIRBAG” are embossed on the air
bag covers.

REAR-WHEEL DRIVE MODELS
FCA US LLC recommends towing your vehicle with all
four wheels OFF the ground using a flatbed.
If flatbed equipment is not available, and the transmission
is operable, the vehicle may be towed (with rear wheels off
the ground) under the following conditions:
 The transmission must be in NEUTRAL (N). For instruc -
tions on shifting the transmission to NEUTRAL (N) when
the engine is off
Úpage 303.
 The towing speed must not exceed 30 mph (48 km/h).
 The towing distance must not exceed 30 miles
(48 km). If the transmission is not operable, or the vehicle must be
towed faster than 30 mph (48 km/h) or farther than
30 miles (48 km), tow with the rear wheels OFF the
ground. Acceptable methods are to tow the vehicle on a
flatbed, or with the front wheels raised and the rear
wheels on a towing dolly, or (when using a suitable
steering wheel stabilizer to hold the front wheels in the
straight position) with the rear wheels raised and the front
wheels ON the ground.
FOUR-WHEEL DRIVE MODELS
FCA US LLC recommends towing with all wheels OFF the
ground. Acceptable methods are to tow the vehicle on a
flatbed or with one end of the vehicle raised and the
opposite end on a towing dolly.
If flatbed equipment is not available, and the transfer case
is operable, vehicles with a two-speed transfer case may
be towed (in the forward direction, with ALL wheels on the
ground), IF the transfer case is in NEUTRAL (N) and the
transmission is in PARK
Úpage 190.
Vehicles equipped with a single-speed transfer case have
no NEUTRAL (N) position, and therefore must be towed will
all four wheels OFF the ground.
CAUTION!
Do not use sling type equipment when towing.
Vehicle damage may occur.
 When securing the vehicle to a flatbed truck, always
secure by tire/wheel straps. Do not attach to front or
rear suspension components, body or frame.
Damage to your vehicle will result from improper
towing.
CAUTION!
Towing faster than 30 mph (48 km/h) or farther than
30 miles (48 km) with rear wheels on the ground can
cause severe transmission damage. Damage from
improper towing is not covered under the New
Vehicle Limited Warranty.
CAUTION!
Front or rear wheel lifts must not be used (if the
remaining wheels are on the ground). Internal
damage to the transmission or transfer case will
occur if a front or rear wheel lift is used when towing.
 Towing this vehicle in violation of the approved
requirements can cause severe transmission and/or
transfer case damage. Damage from improper
towing is not covered under the New Vehicle Limited
Warranty.
