2023 JEEP WAGONEER tire pressure

114GETTING TO KNOW YOUR INSTRUMENT PANEL
Tire Pressure Monitoring System (TPMS)
Warning Light
The warning light switches on and a message is
displayed to indicate that the tire pressure is
lower than the recommended value and/or
that slow pressure loss is occurring. In these
cases, optimal tire duration and fuel consumption may not
be guaranteed.
Should one or more tires be in the condition mentioned
previously, the display will show the indications
corresponding to each tire.
Each tire, including the spare (if provided), should be
checked monthly when cold and inflated to the inflation
pressure recommended by the vehicle manufacturer on
the vehicle placard or tire inflation pressure label. If your
vehicle has tires of a different size than the size indicated
on the vehicle placard or tire inflation pressure label, you
should determine the proper tire inflation pressure for
those tires. As an added safety feature, your vehicle has been
equipped with a TPMS that illuminates a low tire pressure
telltale when one or more of your tires is significantly
underinflated. Accordingly, when the low tire pressure
telltale illuminates, you should stop and check your tires
as soon as possible, and inflate them to the proper
pressure. Driving on a significantly underinflated tire
causes the tire to overheat and can lead to tire failure.
Underinflation also reduces fuel efficiency and tire tread
life, and may affect the vehicle’s handling and stopping
ability.
Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver’s responsibility to
maintain correct tire pressure, even if underinflation has
not reached the level to trigger illumination of the TPMS
low tire pressure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is not
operating properly. The TPMS malfunction indicator is
combined with the low tire pressure telltale. When the
system detects a malfunction, the telltale will flash for
approximately one minute and then remain continuously
illuminated. This sequence will continue upon subsequent
vehicle start-ups as long as the malfunction exists. When
the malfunction indicator is illuminated, the system may
not be able to detect or signal low tire pressure as
intended. TPMS malfunctions may occur for a variety of
reasons, including the installation of replacement or
alternate tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check the TPMS
malfunction telltale after replacing one or more tires or
wheels on your vehicle to ensure that the replacement or
alternate tires and wheels allow the TPMS to continue to
function properly

Towing Hook Breakdown Warning Light —
If Equipped
This light illuminates when there is a failure
with the tow hook. Contact an authorized
dealer for service.
YELLOW INDICATOR LIGHTS
4WD Low Indicator Light — If Equipped
This light alerts the driver that the vehicle is in
the 4WD Low mode. The front and rear
driveshafts are mechanically locked together
forcing the front and rear wheels to rotate at
the same speed. Low range provides a greater gear
reduction ratio to provide increased torque at the wheels
Úpage 129.
CAUTION!
Do not continue driving with one or more flat tires as
handling may be compromised. Stop the vehicle,
avoiding sharp braking and steering. If a tire puncture
occurs, repair immediately using the dedicated tire
repair kit and contact an authorized dealer as soon as
possible.
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system
operation or sensor damage may result when using
replacement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Using aftermarket tire sealants may
cause the Tire Pressure Monitoring System (TPMS)
sensor to become inoperable. After using an
aftermarket tire sealant it is recommended that you
take your vehicle to an authorized dealer to have your
sensor function checked.

134STARTING AND OPERATING
NOTE:Default Ride Height:
 Select Aero Height or Normal Ride Height as the default
for all vehicle speeds and operation. This is the
selected height that the suspension will level for speed
changes (e.g. raising from Entry/Exit Height at speed,
lowering from Off Road Height at speed, etc.).
 Default ride height can be changed by manually
adjusting the Quadra-Lift switch to Normal Ride Height
or Aero Ride Height and stay in the selected height for
2.5 seconds. It will be stored as the default ride height
and the height will be maintained until a new default
ride height is selected.
If equipped with a Uconnect Touchscreen Radio, all
enabling/disabling of air suspension features must be
done through the radio
Úpage 197.
AIR SUSPENSION MODES
The Air Suspension system has multiple modes to protect
the system in unique situations: Tire/Jack Mode
To assist with changing a spare tire, the air suspension
system has a feature which allows the automatic leveling
to be disabled
Úpage 197. Tire/Jack mode is used for
connecting a trailer with a weight-distributing hitch
Úpage 179.
NOTE:This mode is intended to be enabled with the engine
running.
Auto Entry/Exit Mode
To assist in entering and exiting the vehicle, the air
suspension system has a feature which automatically
lowers the vehicle to Entry/Exit Height
Úpage 197.
NOTE:This mode is intended to be enabled with the engine
running. When towing, the automatic Entry/Exit feature
may be disabled through the Uconnect Touchscreen Radio
to prevent vehicle and trailer movement when the gear
selector is moved to PARK.
Transport Mode
To assist with flatbed towing, the air suspension system
has a feature which will put the vehicle into Entry/Exit
Height and disable the automatic load leveling system
Úpage 197.
NOTE:This mode is intended to be enabled with engine running. Suspension Display Messages Mode
The “Suspension Display Messages” setting allows you to
only display suspension warnings instead of all
suspension messages (i.e., “Normal Height Achieved”)
Úpage 197.
NOTE:This mode is intended to be enabled with the engine
running.
Wheel Alignment Mode
Before performing a wheel alignment this mode must be
enabled which will move the vehicle to Normal Ride Height
and disable the air suspension during the alignment
Úpage 197.
NOTE:This mode is intended to be enabled with the engine
running.
If equipped with a Uconnect Touchscreen Radio, all
enabling/disabling of air suspension features must be
done through the radio

STARTING AND OPERATING139
(Continued)
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 tap on the brake pedal, pushing the CANC button, or
normal brake pressure while slowing the vehicle will
deactivate the Cruise Control system 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
Pushing the on/off button or placing the ignition in the OFF
position, will also erase 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
Úpage 138.
ACC will allow you to keep Cruise Control engaged in light
to moderate traffic conditions without the constant need
to reset your Cruise Control. ACC utilizes a radar sensor
and a forward facing camera designed to detect a vehicle
directly ahead of you.
NOTE:
 If the ACC sensor detects a vehicle ahead, ACC will
apply limited braking or acceleration (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 modifications to
the vehicle will affect the performance of the Adaptive
Cruise Control and Forward Collision Warning system.
 In vehicles NOT equipped with the Active Driving Assist
system, Fixed Speed Cruise Control (ACC not enabled)
will not detect vehicles directly ahead of you. Always be
aware of the feature selected
Úpage 382.
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!
 Adaptive Cruise Control (ACC) is a convenience
system. It is not a substitute for active driver involve -
ment. It is always the driver’s responsibility to be
attentive of road, traffic, and weather conditions,
vehicle speed, distance to the vehicle ahead 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 colli -
sion and death or serious personal injury.
 The ACC system:
 Does not react to pedestrians, oncoming vehi -
cles, and stationary objects (e.g., a stopped
vehicle in a traffic jam or a disabled vehicle).
 Cannot take street, traffic, and weather condi -
tions into account, and may be limited upon
adverse sight distance conditions.

178STARTING AND OPERATING
VEHICLE LOADING
GROSS VEHICLE WEIGHT RATING
(GVWR)
The GVWR is the total allowable weight of your vehicle.
This includes driver, passengers, cargo and tongue
weight. The total load must be limited so that you do not
exceed the GVWR.
PAYLOAD
The payload of a vehicle is defined as the allowable weight
a vehicle 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, do not necessarily increase the
vehicle's GVWR or GAWR.
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 axles.
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.
NOTE:

Improper weight distributions can have an adverse
effect on the way your vehicle steers and handles and
the way the brakes operate.
 Air suspension vehicle may limit off-road heights if
loaded beyond recommended values for vehicle GVWR
and GAWR.
TRAILER TOWING
In this section you will find safety tips and information on
limits to the type of towing you can reasonably do with your
vehicle. Before towing a trailer, carefully review this
information to tow your load as efficiently and safely as
possible.
To maintain the New Vehicle Limited Warranty coverage,
follow the requirements and recommendations in this
manual concerning vehicles used for trailer towing.
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.

23_WS_OM_EN_USC_t.book Page 178

186STARTING AND OPERATING
Towing Requirements — Tires
Do not attempt to tow a trailer while using a compact
spare tire.
 Do not drive more than 50 mph (80 km/h) when towing
while using a full-size spare tire.
 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 349.
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 actu -
ated brakes. When towing a trailer equipped with a
hydraulic surge actuated brake system, an electronic
brake controller is not required.
 Trailer brakes are recommended for trailers over
1,000 lb (453 kg) and required for trailers in excess of
2,000 lb (907 kg).
Integrated Trailer Brake Module (ITBM) —
If Equipped
Your vehicle may have an ITBM for Electric and Electric
Over Hydraulic (EOH) trailer brakes. The controller is
located below the instrument panel on the right side of the
steering column.
NOTE:This module has been designed and verified with electric
trailer brakes and EOH systems. Some previous EOH
systems may not be compatible with ITBM.

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
WARNING!
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 acci -
dent.
 Towing any trailer will increase your stopping
distance. When towing, you should allow for addi -
tional 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.

252SAFETY
Pedestrian Emergency Braking (PEB)
PEB is a subsystem of the Forward Collision Warning
(FCW) system which provides the driver with audible
warnings and visual warnings, in the instrument cluster
display. It may apply limited automatic braking when it
detects a potential frontal collision with a pedestrian/
cyclist.

PEB Message

If a PEB event begins at a speed below 39 mph (62 km/h),
the system may provide maximum braking to mitigate the
potential collision with a pedestrian/cyclist. If the PEB
event stops the vehicle completely, the system will hold
the vehicle at a standstill for two seconds and then
release the brakes. When the system determines a
collision with the pedestrian/cyclist in front of you is no
longer probable, the warning message will be deactivated.
The minimum speed for PEB activation is 3 mph (5 km/h). Turning PEB On Or Off
NOTE:The default status of PEB is “On.” This allows the system
to warn you of a possible frontal collision with the pedes
-
trian/cyclist.
The PEB button is located in the Uconnect display in the
control settings
Úpage 197.
To turn the PEB system off, push the Pedestrian
Emergency Braking button once.
To turn the PEB system back on, push the Pedestrian
Emergency Braking button again.
Changing the PEB status to “Off” deactivates the system,
so no warning or active braking will be available in case of
a possible frontal collision with the pedestrian/cyclist.
NOTE:The PEB system will retain the last setting selected by the
driver after ignition shut down. The system will not reset to
the default setting when the vehicle is restarted.
Intersection Collision Assist (ICA) —
If Equipped
ICA uses three front radar sensors located in the front
fascia/bumper, to detect oncoming vehicles from the front
or side when driving through an intersection. When the
system determines that a collision is probable when
turning across oncoming traffic, the system will attempt to
mitigate a possible collision by decelerating the vehicle.
When the system determines that a collision with a
crossing vehicle is probable, the system may apply
additional braking to supplement the driver braking input
to attempt to mitigate a possible collision. The system will
also provide audible warnings and visual warnings (shown
in the instrument cluster). If the driver determines
acceleration is needed to avoid a collision, when the
accelerator is pressed ICA will cancel.
TIRE PRESSURE MONITORING SYSTEM
(TPMS)
The TPMS will warn the driver of a low tire pressure based
on the vehicle recommended cold tire pressure.
The tire pressure will vary with temperature by about 1 psi
(7 kPa) for every 12°F (6.5°C). This means that when the
outside temperature decreases, the tire pressure will
decrease. Tire pressure should always be set based on
cold inflation tire pressure. This is defined as the tire
pressure after the vehicle has not been driven for at least
three hours, or driven less than 1 mile (1.6 km) after a
three-hour period. The tire pressure will also increase as
the vehicle is driven — this is normal and there should be
no adjustment for this increased pressure.
WARNING!
Pedestrian Emergency Braking (PEB) is not intended to
avoid a collision on its own, nor can PEB detect every
type of potential collision with a pedestrian. The driver
has the responsibility to avoid a collision by controlling
the vehicle via braking and steering. Failure to follow
this warning could lead to serious injury or death.

23_WS_OM_EN_USC_t.book Page 252

SAFETY253
(Continued)
For information on how to properly inflate the vehicle’s
tires, see
Úpage 349.
The TPMS will warn the driver of a low tire pressure if the
tire pressure falls below the low pressure warning
threshold for any reason, including low temperature
effects, or natural pressure loss through the tire.
The TPMS will continue to warn the driver of low tire
pressure as long as the condition exists, and will not turn
off until the tire pressure is at or above recommended cold
tire pressure. Once the low tire pressure warning has been
illuminated, the tire pressure must be increased to the
recommended cold tire pressure in order for the TPMS
Warning Light to be turned off.
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 and the TPMS
Warning Light will extinguish once the updated tire
pressures 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. For example, your vehicle has a recommended cold
(parked for more than three hours) tire pressure of 33 psi
(227 kPa). If the ambient temperature is 68°F (20°C) and
the measured tire pressure is 28 psi (193 kPa), a
temperature drop to 20°F (-7°C) will decrease the tire
pressure to approximately 24 psi (165 kPa). This tire
pressure is sufficiently low enough to turn on the TPMS
Warning Light. Driving the vehicle may cause the tire
pressure to rise to approximately 28 psi (193 kPa), but the
TPMS Warning Light will still be on. In this situation, the
TPMS Warning Light will turn off only after the tires have
been inflated to the vehicle’s recommended cold tire
pressure value.NOTE:

The TPMS is not intended to replace normal tire care
and maintenance, or to provide warning of a tire failure
or condition.
 The TPMS should not be used as a tire pressure gauge
while adjusting your tire pressure.
 Driving on a significantly underinflated tire causes the
tire to overheat and can lead to tire failure. Underinfla -
tion also reduces fuel efficiency and tire tread life, and
may affect the vehicle’s handling and stopping ability.
 The TPMS is not a substitute for proper tire mainte -
nance, and it is the driver’s responsibility to maintain
correct tire pressure using an accurate tire gauge, even
if underinflation has not reached the level to trigger illu -
mination of the TPMS Warning Light.
 Seasonal temperature changes will affect tire pres -
sure, and the TPMS will monitor the actual tire pres -
sure in the tire.
CAUTION!
 The TPMS has been optimized for the original equip -
ment tires and wheels. TPMS pressures and warn -
ings have been established for the tire size equipped
on your vehicle. Undesirable system operation or
sensor damage may result when using replacement
equipment that is not of the same size, type, and/or
style. The TPMS sensor is not designed for use on
aftermarket wheels and may contribute to a poor
overall system performance or sensor damage.
Customers are encouraged to use Original Equip -
ment Manufacturer (OEM) wheels to ensure proper
TPMS feature operation.
 Using aftermarket tire sealants may cause the Tire
Pressure Monitoring System (TPMS) sensor to
become inoperable. After using an aftermarket tire
sealant it is recommended that you take your vehicle
to an authorized dealership to have your sensor func -
tion checked.
 After inspecting or adjusting the tire pressure, always
reinstall the valve stem cap. This will prevent mois -
ture and dirt from entering the valve stem, which
could damage the Tire Pressure Monitoring System
sensor.
CAUTION!

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.
