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.
2020_JEEP_JL_WRANGLER_UG_RHD_UK.book Page 97

SAFETY
98
(Continued)
3. If a child from 2 to 12 years old (not in arear-facing child restraint) must ride in
the front passenger seat, move the seat
as far back as possible and use the
proper child restraint. Refer to “Child
Restraints” in this section for further
information.
4. Never allow children to slide the shoulder belt behind them or under their arm.
5. You should read the instructions provided with your child restraint to make
sure that you are using it properly.
6. All occupants should always wear their lap and shoulder belts properly.
7. The driver and front passenger seats should be moved back as far as practical
to allow the front air bags room to inflate.
8. Do not lean against the door or window. If your vehicle has side air bags, and
deployment occurs, the side air bags will
inflate forcefully into the space between
occupants and the door and occupants
could be injured. 9. If the air bag system in this vehicle needs
to be modified to accommodate a
disabled person, refer to the “Customer
Assistance” section for customer service
contact information.
Seat Belt Systems
Buckle up even though you are an excellent
driver, even on short trips. Someone on the
road may be a poor driver and could cause a
collision that includes you. This can happen
far away from home or on your own street.
Research has shown that seat belts save
lives, and they can reduce the seriousness of
injuries in a collision. Some of the worst inju -
ries happen when people are thrown from the
vehicle. Seat belts reduce the possibility of
ejection and the risk of injury caused by
striking the inside of the vehicle. Everyone in
a motor vehicle should be belted at all times.
WARNING!

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 air bag 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.

Enhanced Seat Belt Use Reminder System
(BeltAlert)
Front Seat and Second Row BeltAlert (If
Equipped) BeltAlert is a feature intended to remind
the driver and outboard front seat passenger
to buckle their seat belts. The BeltAlert
feature is active whenever the ignition switch
is in the START or ON/RUN position.
Initial Indication
If the driver is unbuckled when the ignition
switch is first in the START or ON/RUN posi -
tion, a chime will signal for a few seconds. If
the driver or outboard front seat passenger is
unbuckled when the ignition switch is first in
the START or ON/RUN position, the respec -
tive Seat Belt Reminder Light will turn solid
red and remain red until the seat belt is
buckled. The respective Seat Belt Reminder
Light will turn solid green once the seat belt
is buckled. After the driver and outboard
front seat passenger have buckled their seat
belts all Seat Belt Reminder Lights will turn
off. The outboard front passenger seat
BeltAlert is not active when the outboard
front passenger seat is unoccupied. BeltAlert Warning Sequence
The BeltAlert warning sequence is activated
when the vehicle is moving above a specified
vehicle speed range and the driver or
outboard front seat passenger is unbuckled
(the outboard front passenger seat BeltAlert
is not active when the outboard front
passenger seat is unoccupied). The BeltAlert
warning sequence starts by blinking the
respective Seat Belt Reminder Light and
sounding an intermittent chime. Once the
BeltAlert warning sequence has completed,
the Seat Belt Reminder Light will remain
solid red until the driver and outboard front
seat passenger are buckled. The BeltAlert
warning sequence may repeat based on
vehicle speed until the driver and occupied
outboard front seat passenger seat belts are
buckled. The driver should instruct all occu
-
pants to buckle their seat belts.
Change of Status
If the driver or outboard front seat passenger
unbuckles their seat belt while the vehicle is
traveling, the BeltAlert warning sequence
will begin until the seat belts are buckled
again. The outboard front passenger seat BeltAlert
is not active when the outboard front
passenger seat is unoccupied. BeltAlert may
be triggered when an animal or other items
are placed on the outboard front passenger
seat or when the seat is folded flat (if
equipped). It is recommended that pets be
restrained in the rear seat (if equipped) in
pet harnesses or pet carriers that are secured
by seat belts, and cargo is properly stowed.
Rear Seat BeltAlert (If Equipped)
Rear Seat BeltAlert shows the driver whether
the seat belts in the rear seat are buckled or
unbuckled (if equipped with Rear Seat
BeltAlert). When the ignition switch is in the
START or ON/RUN position, a Seat Belt
Reminder Light located in the upper right
corner of the instrument cluster turns on for
each second row seat position (if equipped
with Rear Seat BeltAlert). The Rear BeltAlert
warning sequence is activated when the
vehicle is moving above a specified vehicle
speed range.
If a second row seat belt is buckled, the Rear
BeltAlert Reminder light for that seating
position will illuminate solid green. If a rear
seat passenger is not wearing the seat belt,
the BeltAlert warning sequence will start (if
2020_JEEP_JL_WRANGLER_UG_RHD_UK.book Page 99

(Continued)
equipped with Rear Seat BeltAlert). The
respective Seat Belt Reminder light will illu -
minate solid red. If the seat belt is not
buckled when the vehicle exceeds a speci -
fied speed, the Rear Seat Belt Reminder
light will flash red and a continuous chime
will sound for approximately 30 seconds if
there is no change of status of the rear seat
belt buckles. If a rear seat passenger
unbuckles a seat belt while the vehicle is
travelling, the warning sequence will start
again and the Rear Seat Belt Reminder Light
for that position will change from green to
red. This will alert the driver to stop the
vehicle until the rear seat passenger buckles
the seat belt again. All rear seat BeltAlert
lights will remain illuminated for approxi -
mately 60 seconds (if equipped with Rear
Seat BeltAlert).

The Belt Reminder light will indicate if a rear
seat is not occupied and the seat belt is
unbuckled . If the rear seat is removed (for
vehicles with a removable rear seat) the Belt
Reminder light will illuminate two dashes .

Driver and Front Passenger BeltAlert can be
activated or deactivated by an authorized
dealer. Rear Seat BeltAlert cannot be deacti -
vated. FCA does not recommend deacti -
vating BeltAlert. NOTE:
If Front BeltAlert has been deactivated, the
Front Seat Belt Reminder Light will turn on
and remain on until the driver and outboard
front seat passenger seat belts are buckled.
Lap/Shoulder Belts
All seating positions in your vehicle are
equipped with lap/shoulder belts.
The seat belt webbing retractor will lock only
during very sudden stops or collisions. This
feature allows the shoulder part of the seat
belt to move freely with you under normal
conditions. However, in a collision the seat
belt will lock and reduce your risk of striking
the inside of the vehicle or being thrown out
of the vehicle.
WARNING!
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,
the air bags won’t deploy at all. Always
wear your seat belt even though you have
air bags.
In a collision, you and your passengers
can suffer much greater injuries if you
are not properly buckled up. You can
strike the interior of your vehicle or other
passengers, or you can be thrown out of
the vehicle. Always be sure you and
others in your vehicle are buckled up
properly.

It is dangerous to ride in a cargo area,
inside or outside of a vehicle. In a collision,
people riding in these areas are more likely
to be seriously injured or killed.

Do not allow people to ride in any area of
your vehicle that is not equipped with
seats and seat belts.

Be sure everyone in your vehicle is in a seat
and using a seat belt properly. Occupants,
including the driver, should always wear
their seat belts whether or not an air bag is
also provided at their seating position to
minimize the risk of severe injury or death
in the event of a crash.

WARNING! (Continued)

(Continued)
(Continued)
Wearing your seat belt incorrectly could
make your injuries in a collision much
worse. You might suffer internal injuries,
or you could even slide out of the seat
belt. Follow these instructions to wear
your seat belt safely and to keep your
passengers safe, too.

Two people should never be belted into a
single seat belt. People belted together can
crash into one another in a collision,
hurting one another badly. Never use a lap/
shoulder belt or a lap belt for more than
one person, no matter what their size.

WARNING!
A lap belt worn too high can increase the
risk of injury in a collision. The seat belt
forces won’t be at the strong hip and
pelvic bones, but across your abdomen.
Always wear the lap part of your seat belt
as low as possible and keep it snug.
WARNING! (Continued)
A twisted seat belt may not protect you
properly. In a collision, it could even cut
into you. Be sure the seat belt is flat
against your body, without twists. If you
can’t straighten a seat belt in your
vehicle, take it to an authorized dealer
immediately and have it fixed.
A seat belt that is buckled into the wrong
buckle will not protect you properly. The
lap portion could ride too high on your
body, possibly causing internal injuries.
Always buckle your seat belt into the
buckle nearest you.
A seat belt that is too loose will not
protect you properly. In a sudden stop,
you could move too far forward,
increasing the possibility of injury. Wear
your seat belt snugly.
WARNING! (Continued)
A seat belt that is worn under your arm is
dangerous. Your body could strike the
inside surfaces of the vehicle in a colli -
sion, increasing head and neck injury. A
seat belt worn under the arm can cause
internal injuries. Ribs aren’t as strong as
shoulder bones. Wear the seat belt over
your shoulder so that your strongest
bones will take the force in a collision.
A shoulder belt placed behind you will
not protect you from injury during a colli -
sion. You are more likely to hit your head
in a collision if you do not wear your
shoulder belt. The lap and shoulder belt
are meant to be used together.
A frayed or torn seat belt could rip apart
in a collision and leave you with no
protection. Inspect the seat belt system
periodically, checking for cuts, frays, or
loose parts. Damaged parts must be
replaced immediately. Do not disas-
semble or modify the seat belt system.
Seat belt assemblies must be replaced
after a collision.

Lap/Shoulder Belt Untwisting Procedure
Use the following procedure to untwist a
twisted lap/shoulder belt.
1. Position the latch plate as close aspossible to the anchor point.
2. At about 6 to 12 inches (15 to 30 cm) above the latch plate, grasp and twist the
seat belt webbing 180 degrees to create
a fold that begins immediately above the
latch plate.
3. Slide the latch plate upward over the folded webbing. The folded webbing
must enter the slot at the top of the latch
plate.
4. Continue to slide the latch plate up until it clears the folded webbing and the seat
belt is no longer twisted.
Adjustable Upper Shoulder Belt Anchorage
In the driver and outboard front passenger
seats, the top of the shoulder belt can be
adjusted upward or downward to position the
seat belt away from your neck. Push or
squeeze the anchorage button to release the
anchorage, and move it up or down to the
position that serves you best. Adjustable Upper Anchorage
As a guide, if you are shorter than average,
you will prefer the shoulder belt anchorage in
a lower position, and if you are taller than
average, you will prefer the shoulder belt
anchorage in a higher position. After you
release the anchorage button, try to move it
up or down to make sure that it is locked in
position.
NOTE:
The adjustable upper shoulder belt
anchorage is equipped with an Easy Up
feature. This feature allows the shoulder belt
anchorage to be adjusted in the upward posi -
tion without pushing or squeezing the
release button. To verify the shoulder belt
anchorage is latched, pull downward on the
shoulder belt anchorage until it is locked into
position.
WARNING!
Wearing your seat belt incorrectly could
make your injuries in a collision much
worse. You might suffer internal injuries,
or you could even slide out of the seat
belt. Follow these instructions to wear
your seat belt safely and to keep your
passengers safe, too.
Position the shoulder belt across the
shoulder and chest with minimal, if any
slack so that it is comfortable and not
resting on your neck. The retractor will
withdraw any slack in the shoulder belt.
Misadjustment of the seat belt could
reduce the effectiveness of the safety
belt in a crash.
Always make all seat belt height adjust -
ments when the vehicle is stationary.

SAFETY
104
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 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 or
in the ACC 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 diagnos
-
tics 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 igni -
tion 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 inter -
mittently 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.
WARNING!
Ignoring the Air Bag Warning Light in your
instrument panel could mean you won’t
have the air bag system to protect you in a
collision. If the light does not come on as
a bulb check when the ignition is first
turned on, stays on after you start the
vehicle, or if it comes on as you drive, have
an authorized dealer service the air bag
system immediately.

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.

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.
