The BSM system sensors operate when the
vehicle is in any forward gear or REVERSE
(R) and enters standby mode when the
vehicle is in PARK (P).
The BSM detection zone covers approxi-
mately one lane width on both sides of the
vehicle, 12 ft (3.7 m). The zone length starts
at the outside mirror and extends approxi -
mately 10 ft (3 m) beyond the rear bumper
of the vehicle. The BSM system monitors the
detection zones on both sides of the vehicle
when the vehicle speed reaches approxi -
mately 6 mph (10 km/h) or higher and will
alert the driver of vehicles in these areas.
NOTE:
The BSM system does NOT alert the driver
about rapidly approaching vehicles that
are outside the detection zones.
The BSM system detection zone does NOT
change if your vehicle is towing a trailer.
Therefore, visually verify the adjacent lane
is clear for both your vehicle and trailer
before making a lane change. If the trailer
or other object (i.e., bicycle, sports equip -ment) extends beyond the side of your
vehicle, this may result in the BSM
warning light remaining illuminated the
entire time the vehicle is in a forward gear.
The Blind Spot Monitoring (BSM) system
may experience drop outs (blinking on and
off) of the side mirror Warning Indicator
lamps when a motorcycle or any small
object remains at the side of the vehicle
for extended periods of time (more than a
couple of seconds).
The area on the rear fascia where the radar
sensors are located must remain free of
snow, ice, and dirt/road contamination so
that the BSM system can function properly.
Do not block the area of the rear fascia where
the radar sensors are located with foreign
objects (bumper stickers, bicycle racks,
etc.).
The BSM system will provide a visual alert in
the appropriate side view mirror based on a
detected object. If the turn signal is then
activated, and it corresponds to an alert
present on that side of the vehicle, an
audible chime will also be sounded. When -
ever a turn signal and detected object are present on the same side at the same time,
both the visual and audio alerts will be
issued. In addition to the audible alert the
radio (if on) will also be muted.
Warning Light Location
The BSM system monitors the detection
zone from three different entry points (side,
rear, front) while driving to see if an alert is
necessary. The BSM system will issue an
alert during these types of zone entries.
Entering From The Side

Modes Of Operation
Three selectable modes of operation are
available in the Uconnect System. Refer to
“Uconnect Settings” in “Multimedia” in the
Owner’s Manual for further information.
Blind Spot Alert Lights Only
When operating in Blind Spot Alert mode,
the BSM system will provide a visual alert in
the appropriate side view mirror based on a
detected object. However, when the system
is operating in Rear Cross Path (RCP) mode,
the system will respond with both visual and
audible alerts when a detected object is
present. Whenever an audible alert is
requested, the radio is muted.
Blind Spot Alert Lights/Chime
When operating in Blind Spot Alert Lights/
Chime mode, the BSM system will provide a
visual alert in the appropriate side view
mirror based on a detected object. If the turn
signal is then activated, and it corresponds
to an alert present on that side of the vehicle,
an audible chime will also be sounded.
Whenever a turn signal and detected objectare present on the same side at the same
time, both the visual and audible alerts will
be issued. In addition to the audible alert the
radio (if on) will also be muted.
NOTE:
Whenever an audible alert is requested by
the BSM system, the radio is also muted.
When the system is in RCP, the system shall
respond with both visual and audible alerts
when a detected object is present. Whenever
an audible alert is requested, the radio is
also muted. Turn/hazard signal status is
ignored; the RCP state always requests the
chime.
Blind Spot Alert Off
When the BSM system is turned off there will
be no visual or audible alerts from either the
BSM or RCP systems.
NOTE:
The BSM system will store the current oper
-
ating mode when the vehicle is shut off.
Each time the vehicle is started the previ -
ously stored mode will be recalled and used.
Forward Collision Warning (FCW) With
Mitigation — If Equipped
FCW With Mitigation Operation
The Forward Collision Warning (FCW) system
with mitigation provides the driver with
audible warnings, visual warnings (within the
instrument cluster display), and may apply a
haptic warning to warn the driver when it
detects a potential frontal collision. The
warnings are intended to provide the driver
with enough time to react, avoid or mitigate
the potential collision.
NOTE:
FCW monitors the information from the
forward looking sensors as well as the Elec -
tronic Brake Controller (EBC), to calculate
the probability of a forward collision. When
the system determines that a forward colli -
sion is probable, the driver will be provided
with audible and visual warnings and may
provide a haptic warning in the form of a
brake jerk.
If the driver does not take action based upon
these progressive warnings, then the system
will provide a limited level of active braking
to help slow the vehicle and mitigate the
potential forward collision. If the driver
reacts to the warnings by braking and the
2020_JEEP_CHEROKEE_UG_RHD_UK.book Page 90

91
system determines that the driver intends to
avoid the collision by braking but has not
applied sufficient brake force, the system
will compensate and provide additional
brake force as required.
If a Forward Collision Warning with Mitiga-
tion event begins at a speed below 32 mph
(52 km/h), the system may provide the
maximum braking possible to mitigate the
potential forward collision. If the Forward
Collision Warning with Mitigation event stops
the vehicle completely, the system will hold
the vehicle at standstill for two seconds and
then release the brakes.
FCW Message
When the system determines a collision with
the vehicle in front of you is no longer prob -
able, the warning message will be deacti -
vated. NOTE:
The minimum speed for FCW activation is
1 mph (2 km/h).

The FCW alerts may be triggered on objects
other than vehicles such as guard rails or
sign posts based on the course prediction.
This is expected and is a part of normal FCW
activation and functionality.

It is unsafe to test the FCW system. To
prevent such misuse of the system, after
four Active Braking events within a key
cycle, the Active Braking portion of FCW
will be deactivated until the next key
cycle.
The FCW system is intended for on-road
use only. If the vehicle is taken off-road,
the FCW system should be deactivated to
prevent unnecessary warnings to the
surroundings.
FCW may not react to irrelevant objects
such as overhead objects, ground reflec-
tions, objects not in the path of the
vehicle, stationary objects that are far
away, oncoming traffic, or leading vehicles
with the same or higher rate of speed.
FCW will be disabled like ACC, with the
unavailable screens.
Turning FCW On or Off
The FCW button is located in the Uconnect
display in the control settings. Refer to
“Uconnect Settings” in “Multimedia” in the
Owner's Manual for further information.
To turn the FCW system on, press the
forward collision button once to turn the
system on.
To turn the FCW system off, press the
forward collision button once to turn the
system off.
WARNING!
Forward Collision Warning (FCW) is not
intended to avoid a collision on its own,
nor can FCW detect every type of potential
collision. 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.

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.
2020_JEEP_CHEROKEE_UG_RHD_UK.book Page 93

95
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.
CAUTION! (Continued)

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.

The SABICs (if equipped with SABICs) may
help reduce the risk of partial or complete
ejection of vehicle occupants through side
windows in certain side impact events.Side Impacts
The Side Air Bags are designed to activate in
certain side impacts. The Occupant
Restraint Controller (ORC) determines
whether the deployment of the Side Air Bags
in a particular impact event is appropriate,
based on the severity and type of collision.
The side impact sensors aid the ORC in
determining the appropriate response to
impact events. The system is calibrated to
deploy the Side Air Bags on the impact side
of the vehicle during impacts that require
Side Air Bag occupant protection. In side
impacts, the Side Air Bags deploy inde
-
pendently; a left side impact deploys the left
Side Air Bags only and a right-side impact
deploys the right Side Air Bags only. Vehicle
damage by itself is not a good indicator of
whether or not Side Air Bags should have
deployed.
The Side Air Bags will not deploy in all side
collisions, including some collisions at
certain angles, or some side collisions that
do not impact the area of the passenger
compartment. The Side Air Bags may deploy
during angled or offset frontal collisions
where the front air bags deploy. Side Air Bags are a supplement to the seat
belt restraint system. Side Air Bags deploy in
less time than it takes to blink your eyes.
WARNING!
Do not mount equipment, or stack
luggage or other cargo up high enough to
block the deployment of the SABICs.
The trim covering above the side
windows where the SABIC and its
deployment path are located should
remain free from any obstructions.
In order for the SABICs to work as
intended, do not install any accessory
items in your vehicle which could alter
the roof. Do not add an aftermarket
sunroof to your vehicle. Do not add roof
racks that require permanent attach
-
ments (bolts or screws) for installation
on the vehicle roof. Do not drill into the
roof of the vehicle for any reason.
WARNING!
Occupants, including children, who are
up against or very close to Side Air Bags
can be seriously injured or killed. Occu -
pants, including children, should never
lean on or sleep against the door, side
windows, or area where the side air bags
inflate, even if they are in an infant or
child restraint.
Seat belts (and child restraints where
appropriate) are necessary for your
protection in all collisions. They also
help keep you in position, away from an
inflating Side Air Bag. To get the best
protection from the Side Air Bags, occu -
pants must wear their seat belts properly
and sit upright with their backs against
the seats. Children must be properly
restrained in a child restraint or booster
seat that is appropriate for the size of the
child.
2020_JEEP_CHEROKEE_UG_RHD_UK.book Page 113

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.
