Entering From The Rear
Vehicles that come up from behind your
vehicle on either side and enter the rear
detection zone with a relative speed of less
than 30 mph (48 km/h).Overtaking Traffic
If you pass another vehicle slowly with a rela -
tive speed less than 15 mph (24 km/h) and
the vehicle remains in the blind spot for
approximately 1.5 seconds, the warning light
will be illuminated. If the difference in speed
between the two vehicles is greater than
15 mph (24 km/h), the warning light will not
illuminate.
The BSM system is designed not to issue an
alert on stationary objects such as guardrails,
posts, walls, foliage, berms, etc. However,
occasionally the system may alert on such
objects. This is normal operation and your
vehicle does not require service.
The BSM system will not alert you of objects
that are traveling in the opposite direction of
the vehicle in adjacent lanes.
Rear Cross Path (RCP)
The Rear Cross Path (RCP) feature is
intended to aid the driver when backing out
of parking spaces where their vision of
oncoming vehicles may be blocked. Proceed
slowly and cautiously out of the parking
space until the rear end of the vehicle is
exposed. The RCP system will then have a
clear view of the cross traffic and if an
oncoming vehicle is detected, alert the
driver.
RCP monitors the rear detection zones on
both sides of the vehicle, for objects that are
moving toward the side of the vehicle with a
minimum speed of approximately 3 mph (5 km/h), to objects moving a maximum of
approximately 20 mph (32 km/h), such as in
parking lot situations.
NOTE:
In a parking lot situation, oncoming vehicles
can be obscured by vehicles parked on either
side. If the sensors are blocked by other
structures or vehicles, the system will not be
able to alert the driver.
When RCP is on and the vehicle is in
REVERSE (R), the driver is alerted using
both the visual and audible alarms, including
reducing the radio volume.
WARNING!
The Blind Spot Monitoring system is only
an aid to help detect objects in the blind
spot zones. The BSM system is not
designed to detect pedestrians, bicyclists,
or animals. Even if your vehicle is
equipped with the BSM system, always
check your vehicle’s mirrors, glance over
your shoulder, and use your turn signal
before changing lanes. Failure to do so can
result in serious injury or death.
WARNING!
Rear Cross Path Detection (RCP) is not a
back up aid system. It is intended to be
used to help a driver detect an oncoming
vehicle in a parking lot situation. Drivers
must be careful when backing up, even
when using RCP. Always check carefully
behind your vehicle, look behind you, and
be sure to check for pedestrians, animals,
other vehicles, obstructions, and blind
spots before backing up. Failure to do so
can result in serious injury or death.

present, the system will return to its full
performance state. If the problem persists,
see an authorized dealer.
Service FCW Warning
If the system turns off, and the instrument
cluster display reads:
ACC/FCW Unavailable Service Required
Cruise/FCW Unavailable Service Required
This indicates there is an internal system
fault. Although the vehicle is still driveable
under normal conditions, have the system
checked by an authorized dealer.
Pedestrian Emergency Braking (PEB) — If
Equipped
Pedestrian Emergency Braking (PEB) is a
sub-system of the FCW system which
provides the driver with audible and visual
warnings in the instrument cluster display,
and may apply automatic braking when it
detects a potential frontal collision with a
pedestrian.
If a PEB event begins at a speed below
37 mph (60 km/h), the system may provide
braking to mitigate the potential collision
with a pedestrian. 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 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 pedestrian.
The PEB button is located in the Uconnect
display in the Controls settings. Refer to
“Uconnect Settings” in “Multimedia” in the
Owner’s Manual for further information.
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” deacti
-
vates the system, so no warning or active
braking will be available in case of a possible
frontal collision with the pedestrian.
NOTE:
The PEB system will NOT retain the last
setting selected by the driver after ignition
shut down. The system will reset to the
default setting when the vehicle is restarted.
Tire Pressure Monitoring System (TPMS)
The Tire Pressure Monitoring System (TPMS)
will warn the driver of a low tire pressure
based on the vehicle recommended cold
placard pressure.
NOTE:
The system only warns the tire pressure is
low: it is not able to inflate them.
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.

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.

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

Switchable Automatic Locking Retractor (ALR) Locations — Sliding and Fixed Seats
If the passenger seating position is equipped
with an ALR and is being used for normal
usage, only pull the seat belt webbing out far
enough to comfortably wrap around the
occupant’s mid-section so as to not activate
the ALR. If the ALR is activated, you will
hear a clicking sound as the seat belt
retracts. Allow the webbing to retract
completely in this case and then carefully
pull out only the amount of webbing neces -
sary to comfortably wrap around the occu -
pant’s mid-section. Slide the latch plate into
the buckle until you hear a "click." In Automatic Locking Mode, the shoulder
belt is automatically pre-locked. The seat
belt will still retract to remove any slack in
the shoulder belt. Use the Automatic
Locking Mode anytime a child restraint is
installed in a seating position that has a seat
belt with this feature. Children 12 years old
and under should always be properly
restrained in the rear seat of a vehicle with a
rear seat.
How To Engage The Automatic Locking Mode
1. Buckle the combination lap and shoulder
belt.
2. Grasp the shoulder portion and pull downward until the entire seat belt is
extracted.
3. Allow the seat belt to retract. As the seat belt retracts, you will hear a clicking
sound. This indicates the seat belt is now
in the Automatic Locking Mode.
How To Disengage The Automatic Locking
Mode
Unbuckle the combination lap/shoulder belt
and allow it to retract completely to disen -
gage the Automatic Locking Mode and acti -
vate the vehicle sensitive (emergency)
locking mode.
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.

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 associ-
ated with the electrical Air Bag System
Components. Your vehicle may be equipped
with the following Air Bag System Compo -
nents:
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
Supplemental Knee Air Bags
Front and Side Impact Sensors
Seat Belt Pretensioners
Seat Track Position Sensors
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
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.
Failure to replace the seat belt assembly
could increase the risk of injury in
collisions.
Do not use the Automatic Locking Mode
to restrain occupants who are wearing
the seat belt or children who are using
booster seats. The locked mode is only
used to install rear-facing or
forward-facing child restraints that have
a harness for restraining the child.

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 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.
For additional information regarding the
Redundant Air Bag Warning Light refer to
“Getting To Know Your Instrument Panel”
section of this manual.
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.

If A Deployment Occurs
The front air bags are designed to deflate
immediately after deployment.
NOTE:
Front and/or side air bags will not deploy in
all collisions. This does not mean something
is wrong with the air bag system.
If you do have a collision which deploys the
air bags, any or all of the following may
occur:
The air bag material may sometimes cause
abrasions and/or skin reddening to the
occupants as the air bags deploy and
unfold. The abrasions are similar to fric-
tion rope burns or those you might get
sliding along a carpet or gymnasium floor.
They are not caused by contact with chem-
icals. They are not permanent and
normally heal quickly. However, if you
haven’t healed significantly within a few
days, or if you have any blistering, see your
doctor immediately.
As the air bags deflate, you may see some
smoke-like particles. The particles are a
normal by-product of the process that
generates the non-toxic gas used for air
bag inflation. These airborne particles may
irritate the skin, eyes, nose, or throat. If
you have skin or eye irritation, rinse the
area with cool water. For nose or throat irri -
tation, move to fresh air. If the irritation
continues, see your doctor. If these parti -
cles settle on your clothing, follow the
garment manufacturer’s instructions for
cleaning.
Do not drive your vehicle after the air bags
have deployed. If you are involved in another
collision, the air bags will not be in place to
protect you. NOTE:
Air bag covers may not be obvious in the
interior trim, but they will open during air
bag deployment.
After any collision, the vehicle should be
taken to an authorized dealer immedi
-
ately.
Enhanced Accident Response System
In the event of an impact, if the communica -
tion network remains intact, and the power
remains intact, depending on the nature of
the event, the Occupant Restraint Controller
(ORC) will determine whether to have the
Enhanced Accident Response System
perform the following functions:
Cut off fuel to the engine (if equipped)
Cut off battery power to the electric motor
(if equipped)
Flash hazard lights as long as the battery
has power
Turn on the interior lights, which remain
on as long as the battery has power or for
15 minutes from the intervention of the
Enhanced Accident Response System
Unlock the power door locks
WARNING!
Deployed air bags and seat belt
pretensioners cannot protect you in
another collision. Have the air bags, seat
belt pretensioners, and the seat belt
retractor assemblies replaced by an
authorized dealer immediately. Also, have
the Occupant Restraint Controller System
serviced as well.

Event Data Recorder (EDR)
This vehicle is equipped with an Event Data
Recorder (EDR). The main purpose of an
EDR is to record, in certain crash or near
crash-like situations, such as an air bag
deployment or hitting a road obstacle, data
that will assist in understanding how a
vehicle’s systems performed. The EDR is
designed to record data related to vehicle
dynamics and safety systems for a short
period of time, typically 30 seconds or less.
The EDR in this vehicle is designed to record
such data as:
How various systems in your vehicle were
operating;
Whether or not the driver and passenger
safety belts were buckled/fastened;
How far (if at all) the driver was depressing
the accelerator and/or brake pedal; and,
How fast the vehicle was traveling.These data can help provide a better under
-
standing of the circumstances in which
crashes and injuries occur.
NOTE:
EDR data are recorded by your vehicle only if
a non-trivial crash situation occurs; no data
are recorded by the EDR under normal
driving conditions and no personal data (e.g.,
name, gender, age, and crash location) are
recorded. However, other parties, such as
law enforcement, could combine the EDR
data with the type of personally identifying
data routinely acquired during a crash inves -
tigation.
To read data recorded by an EDR, special
equipment is required, and access to the
vehicle or the EDR is needed. In addition to
the vehicle manufacturer, other parties, such
as law enforcement, that have the special
equipment, can read the information if they
have access to the vehicle or the EDR.
Do not attempt to modify any part of your
air bag system. The air bag may inflate
accidentally or may not function properly
if modifications are made. Take your
vehicle to an authorized dealer for any air
bag system service. If your seat,
including your trim cover and cushion,
needs to be serviced in any way
(including removal or loosening/tight -
ening of seat attachment bolts), take the
vehicle to an authorized dealer. Only
manufacturer approved seat accessories
may be used. If it is necessary to modify
the air bag system for persons with
disabilities, contact an authorized
dealer.
