NOTE:
The TPMS is not intended to replace
normal tire care and maintenance, or to
provide warning of a tire failure or condi-
tion.
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 responsi -
bility to maintain correct tire pressure using
an accurate tire pressure gauge, even if
underinflation has not reached the level to
trigger illumination of the “Tire Pressure
Monitoring Telltale Light.”

Seasonal temperature changes will affect
tire pressure, and the TPMS will monitor
the actual tire pressure in the tire.
Premium System
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.
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 System Warning
Light
Tire Pressure Monitoring Low Pressure Warnings
The “Tire Pressure Monitoring
Warning Light” will illuminate 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.
After inspecting or adjusting the tire
pressure always reinstall the valve stem
cap. This will prevent moisture and dirt
from entering the valve stem, which
could damage the TPMS sensor.

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 “Tire Pressure
Monitoring Warning Light” will turn 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.
NOTE:
When filling warm tires, the tire pressure
may need to be increased up to an additional
5 psi (35 kPa) above the recommended cold
placard pressure in order to turn the Tire
Pressure Monitoring Warning Light off.
Service TPMS Warning
When a system fault is detected, the “Tire
Pressure Monitoring Warning Light” will
flash on and off for 75 seconds and then
remain on solid. The system fault will also
sound a chime. In addition, the instrument
cluster will display a "SERVICE TPM
SYSTEM" message for a minimum of five
seconds and then display dashes (- -) in
place of the pressure value to indicate which
sensor is not being received.
If the ignition key is cycled, this sequence
will repeat, providing the system fault still
exists. If the system fault no longer exists,
the “Tire Pressure Monitoring Warning
Light” will no longer flash, and the
“SERVICE TPM SYSTEM” message will no
longer display, and a pressure 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.
2020_JEEP_CHEROKEE_UG_RHD_UK.book Page 96

97
2. If you install the compact ornon-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 key 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 Pres -
sure System” message for five seconds
and then display dashes (- -) in place of
the pressure value.
4. For each subsequent ignition key cycle, a chime will sound, the “TPMS Warning0
Light” will flash on and off for 75
seconds and then remain on solid, and
the instrument cluster will display a
“SERVICE TPM 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.
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.
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 "TPM Telltale Light" will flash on and off for 75
seconds and then remain on. The instru
-
ment 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 TPM sensors. Then, drive
the vehicle for up to 10 minutes above
15 mph (24 km/h). The TPMS will chime,
the "TPM Telltale Light" will flash on and off
for 75 seconds and then turn off. The instru -
ment cluster will display the “SERVICE TPM
SYSTEM” message and then display pres -
sure 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.

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. 3. If a child from 2 to 12 years old (not in a
rear-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 needsto 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.
Enhanced Seat Belt Use Reminder System
(BeltAlert)
Front And Rear Seat BeltAlert (If Equipped)
Front Seat BeltAlert
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
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.
Never install a rear-facing child restraint
in the front seat of a vehicle. Only use a
rear-facing child restraint in the rear
seat. If the vehicle does not have a rear
seat, do not transport a rear-facing child
restraint in that vehicle.
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.

(Continued)
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
Rear Seat BeltAlert shows the driver whether
the seat belts in the rear seat are buckled or
unbuckled. When the ignition switch is in the
START or ON/RUN position, a Seat Belt
Reminder Light turns on for each rear seat
position. If a seat belt is buckled, the Seat
Belt Reminder Light for that position will
illuminate solid green. If a seat belt is
unbuckled, the Seat Belt Reminder Light will
illuminate red. If a rear passenger unbuckles
a seat belt that was buckled at the start of
the trip, a single chime will sound and the
Seat Belt Reminder Light for that position
will change from solid green to blinking red.
This will alert the driver to stop the vehicle
until the rear passenger buckles the seat belt
again. After the driver and outboard front
seat passenger have buckled their seat belts
all Seat Belt Reminder Lights will turn off.
BeltAlert can be activated or deactivated by
an authorized dealer. FCA does not recom
-
mend deactivating BeltAlert.
NOTE:
If BeltAlert has been deactivated, the 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 colli -
sion, 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.
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.
WARNING! (Continued)
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.
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.
WARNING! (Continued)
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.
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.

Lap/Shoulder Belt Operating Instructions
1. Enter the vehicle and close the door. Sitback and adjust the seat.
2. The seat belt latch plate is above the back of the front seat, and next to your
arm in the rear seat (for vehicles
equipped with a rear seat). Grasp the
latch plate and pull out the seat belt.
Slide the latch plate up the webbing as
far as necessary to allow the seat belt to
go around your lap. Pulling Out The Latch Plate
3. When the seat belt is long enough to fit, insert the latch plate into the buckle until
you hear a “click.”
Inserting Latch Plate Into Buckle 4. Position the lap belt so that it is snug and
lies low across your hips, below your
abdomen. To remove slack in the lap belt
portion, pull up on the shoulder belt. To
loosen the lap belt if it is too tight, tilt the
latch plate and pull on the lap belt. A
snug seat belt reduces the risk of sliding
under the seat belt in a collision.
Positioning The Lap Belt
5. 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.
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.
