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. Underinflation 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 maintenance, and it is the driver’s
responsibility to maintain correct tire pres-
sure using an accurate tire pressure
gauge, even if underinflation has not
reached the level to trigger illumination of
the TPMS Warning Light.
Seasonal temperature changes will affect
tire pressure, and the TPMS will monitor
the actual tire pressure in the tire.
System Operation
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 Display
NOTE:
It is particularly important for you to check
the tire pressure in all of the tires on your
vehicle monthly and to maintain the proper
pressure. The TPMS consists of the following compo
-
nents:Receiver module
Four tire pressure monitoring sensors
Various tire pressure monitoring system
messages, which display in the instrument
cluster
Tire pressure monitoring telltale light
Tire Pressure Monitoring Low Pressure Warnings
The TPMS Warning Light will illu -
minate in the instrument cluster
and a chime will sound when tire
pressure is low in one or more of the four
active road tires. In addition, the instrument
cluster will display a "Tire Low" message for
a minimum of five seconds and a graphic
showing the pressure values of each tire with
the low tire pressure values in a different
color.

Tire Pressure Monitoring Low Pressure Warning

Should this occur, you should stop as soon as
possible and inflate the tires with low pres -
sure (those in a different color in the instru -
ment cluster graphic) to the vehicle’s
recommended cold placard pressure value.
Once the system receives the updated tire
pressures, the system will automatically
update, the pressure values in the graphic
display in the instrument cluster will return
to their original color, and the TPMS Warning
Light will turn 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 vehicle may need to be driven for up to
10 minutes above 15 mph (24 km/h) in order for
the TPMS to receive this information.
Service TPMS Warning
When a system fault is detected, the TPMS
Warning Light will flash on and off for 75
seconds and then remain on solid. The
system fault will also sound a chime. In addi
-
tion, the instrument cluster will display a
"SERVICE TIRE PRESSURE SYSTEM"
message for a minimum of five seconds and
then display dashes (--) in place of the pres -
sure value to indicate which sensor is not
being received. If the ignition is cycled, this sequence will
repeat, providing the system fault still exists.
If the system fault no longer exists, the
TPMS Warning Light will no longer flash, and
the “SERVICE TIRE PRESSURE SYSTEM”
message will no longer display, and a pres
-
sure value will display in place of the dashes.
A system fault can occur due to any of the
following:
Jamming due to electronic devices or
driving next to facilities emitting the same
radio frequencies as the TPMS sensors
Installing some form of aftermarket
window tinting that affects radio wave
signals
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

Vehicles With Compact Spare or Non-Matching
Full Size Spare
1. The compact spare tire or non-matching full size does not have a tire pressure
monitoring sensor. Therefore, the TPMS
will not monitor the pressure in the
compact spare tire.
2. If you install the compact or non-matching full size spare tire in place
of a road tire that has a pressure below
the low-pressure warning limit, upon the
next ignition cycle, the TPMS Warning
Light will remain on and a chime will
sound. In addition, the graphic in the
instrument cluster will still display a
different color pressure value.
3. After driving the vehicle for up to 10 minutes above 15 mph (24 km/h),
the TPMS Warning Light will flash on and
off for 75 seconds and then remain on
solid. In addition, the instrument cluster
will display a “Service Tire Pressure
System” message for five seconds and
then display dashes (--) in place of the
pressure value. 4. For each subsequent ignition cycle, a
chime will sound, the TPMS Warning
Light will flash on and off for 75 seconds
and then remain on solid, and the instru -
ment cluster will display a “SERVICE
TIRE PRESSURE SYSTEM” message for
five seconds and then display dashes (--)
in place of the pressure value.
5. Once you repair or replace the original road tire and reinstall it on the vehicle in
place of the compact spare or
non-matching full size, the TPMS will
update automatically. In addition, the
TPMS Warning Light will turn off and the
graphic in the instrument cluster 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
10 minutes above 15 mph (24 km/h) in
order for the TPMS to receive this
information. Vehicles With a Full Size Matching Spare
1. If your vehicle is equipped with a
matching full-size spare wheel and tire
assembly, it has a tire pressure moni -
toring sensor, and can be monitored by
the Tire Pressure Monitoring System
(TPMS) when swapped with a low pres -
sure road tire.
2. In the event that the matching full-size spare tire is swapped with a low pressure
road tire, the next ignition switch cycle
will still show the TPMS Warning Light to
be on, a chime to sound, and the graphic
display will still show the low tire pres -
sure value in a different color.
3. Driving the vehicle for up to 10 minutes above 15 mph (24 km/h) will turn off theTPMS Warning Light as long as none of
road tires are below the low pressure
warning threshold.
TPMS Deactivation — If Equipped
The 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.
2020_JEEP_JL_WRANGLER_UG_RHD_UK.book Page 96

97

To deactivate the TPMS, first replace all four
wheel and tire assemblies (road tires) with tires
not equipped with Tire Pressure Monitoring (TPM)
sensors. Then, drive the vehicle for 10 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 TIRE PRES-
SURE 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
TIRE PRESSURE 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 10 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 instru -
ment cluster will display the “SERVICE TIRE
PRESSURE SYSTEM” message and then
display pressure values in place of the
dashes. On the next ignition cycle the
"SERVICE TIRE PRESSURE SYSTEM"
message will no longer be displayed as long
as no system fault exists.OCCUPANT RESTRAINT
SYSTEMS
Some of the most important safety features
in your vehicle are the restraint systems:
Occupant Restraint Systems Features
Seat Belt Systems
Supplemental Restraint Systems (SRS)
Air Bags
Child Restraints
Some of the safety features described in this
section may be standard equipment on some
models, or may be optional equipment on
others. If you are not sure, ask an authorized
dealer.
Important Safety Precautions
Please pay close attention to the information
in this section. It tells you how to use your
restraint system properly, to keep you and
your passengers as safe as possible. Here are some simple steps you can take to
minimize the risk of harm from a deploying
air bag:
1. Children 12 years old and under should
always ride buckled up in the rear seat of
a vehicle with a rear seat.
Warning Label On Front Passenger Sun Visor
2. A child who is not big enough to wear the vehicle seat belt properly (Refer to “Child
Restraints” in this section for further
information) must be secured in the
appropriate child restraint or belt-posi -
tioning booster seat in a rear seating
position.

Seat Belts And Pregnant Women
Seat Belts And Pregnant Women
Seat belts must be worn by all occupants
including pregnant women: the risk of injury
in the event of an accident is reduced for the
mother and the unborn child if they are
wearing a seat belt.

Position the lap belt snug and low below the
abdomen and across the strong bones of the hips.
Place the shoulder belt across the chest and away
from the neck. Never place the shoulder belt
behind the back or under the arm.

Seat Belt Pretensioner

The front outboard seat belt system is equipped
with pretensioning devices that are designed to
remove slack from the seat belt in the event of
a collision. These devices may improve the performance of the seat belt by removing slack
from the seat belt early in a collision. Preten
-
sioners work for all size occupants, including
those in child restraints.

NOTE:
These devices are not a substitute for proper
seat belt placement by the occupant. The
seat belt still must be worn snugly and posi -
tioned properly.
The pretensioners are triggered by the Occu -
pant Restraint Controller (ORC). Like the air
bags, the pretensioners are single use items.
A deployed pretensioner or a deployed air
bag must be replaced immediately.
Energy Management Feature

The front outboard seat belt system is equipped
with an Energy Management feature that may
help further reduce the risk of injury in the event
of a collision. The seat belt system has a retractor
assembly that is designed to release webbing in a
controlled manner.

Supplemental Restraint Systems (SRS)

Some of the safety features described in this
section may be standard equipment on some
models, or may be optional equipment on others.
If you are not sure, ask an authorized dealer.
The air bag system must be ready to protect you
in a collision. The Occupant Restraint
Controller (ORC) monitors the internal circuits
and interconnecting wiring associated with the
electrical Air Bag System Components. Your
vehicle may be equipped with the following Air
Bag System Components:

Air Bag System Components
Occupant Restraint Controller (ORC)
Air Bag Warning Light
Steering Wheel and Column
Instrument Panel
Knee Impact Bolsters
Driver and Front Passenger Air Bags
Seat Belt Buckle Switch
Supplemental Side Air Bags
Front and Side Impact Sensors
Seat Belt Pretensioners
Seat Track Position Sensors

for further information.
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 supple-
ment 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.
Front Air Bag/Knee Impact Bolster LocationsDriver And Passenger Front Air Bag Features
The front air bag system is designed to
inflate based on the severity and type of
collision as determined by the Occupant
Restraint Controller (ORC), which may
receive information from the front impact
sensors (if equipped) or other system compo -
nents. The driver front air bag system has a
single stage air bag. The passenger front air
bag system has a multistage front air bag.
The first stage inflator is triggered immedi -
ately during an impact that requires air bag
deployment. For the multistage air bag, a low
energy output is used in less severe colli -
sions. A higher energy output is used for
more severe collisions.

This vehicle may be equipped with a driver and/or
front passenger seat belt buckle switch that
detects whether the driver or front passenger seat
belt is buckled. The seat belt buckle switch may
adjust the inflation rate of the passenger multi -
stage Front Air Bag.

1 — Driver And Passenger Front Air Bags

2 — Driver And Passenger Knee Impact Bolster

WARNING!
Being too close to the steering wheel or
instrument panel during front air bag
deployment could cause serious injury,
including death. Air bags need room to
inflate. Sit back, comfortably extending
your arms to reach the steering wheel or
instrument panel.

NEVER use a rearward facing child
restraint on a seat protected by an ACTIVE
AIRBAG in front of it, DEATH or SERIOUS
INJURY to the CHILD can occur.

It is advisable to always carry children in
a child restraint system on the rear seat,
which is the most protected position in
the event of a collision.
Should it be necessary to carry a child on
the passenger side front seat in a
rear-facing child restraint system, the
passenger side front airbag must be
deactivated. Always make sure the
airbag deactivation indicator light is illu
-
minated when using a child restraint
system. The passenger seat must also be
positioned backward as far as possible to
avoid the child restraint system from
coming into contact with the dashboard.
A deploying passenger front air bag can
cause death or serious injury to a child
12 years or younger, including a child in
a rear-facing child restraint.

This vehicle may be equipped with driver
and/or front passenger seat track position
sensors that may adjust the inflation rate of
the Advanced Front Air Bags based upon
seat position.Front Air Bag Operation
Front Air Bags are designed to provide addi-
tional protection by supplementing the seat
belts. Front air bags are not expected to
reduce the risk of injury in rear, side, or roll -
over collisions. The front air bags will not
deploy in all frontal collisions, including
some that may produce substantial vehicle
damage — for example, some pole colli -
sions, truck underrides, and angle offset
collisions.
On the other hand, depending on the type
and location of impact, front air bags may
deploy in crashes with little vehicle front-end
damage but that produce a severe initial
deceleration.
Because air bag sensors measure vehicle
deceleration over time, vehicle speed and
damage by themselves are not good indica -
tors of whether or not an air bag should have
deployed.
Seat belts are necessary for your protection
in all collisions, and also are needed to help
keep you in position, away from an inflating
air bag. When the ORC detects a collision requiring
the front air bags, it signals the inflator units.
A large quantity of non-toxic gas is generated
to inflate the front air bags.
The steering wheel hub trim cover and the
upper passenger side of the instrument
panel separate and fold out of the way as the
air bags inflate to their full size. The front air
bags fully inflate in less time than it takes to
blink your eyes. The front air bags then
quickly deflate while helping to restrain the
driver and front passenger.
Passenger Air Bag Disable Feature — If
Equipped
This system allows the driver to DISABLE
(OFF) the Passenger Advanced Front Air Bag
if a child restraint
must be installed in the
front seat. Only DISABLE (OFF) the
Passenger Advanced Front Air Bag if it is
absolutely necessary to install a child
restraint in the front seat. Children 12 years
or younger should ride properly buckled up in
a rear seat, if available. According to crash
statistics, children are safer when properly
restrained in the rear seats rather than in the
front. (Refer to “Child Restraints” in this
section for further information.)
WARNING!
No objects should be placed over or near
the air bag on the instrument panel or
steering wheel because any such objects
could cause harm if the vehicle is in a
collision severe enough to cause the air
bag to inflate.
Do not put anything on or around the air
bag covers or attempt to open them
manually. You may damage the air bags
and you could be injured because the air
bags may no longer be functional. The
protective covers for the air bag cushions
are designed to open only when the air
bags are inflating.
Relying on the air bags alone could lead
to more severe injuries in a collision. The
air bags work with your seat belt to
restrain you properly. In some collisions,
air bags won’t deploy at all. Always wear
your seat belts even though you have air
bags.
