The gear selection must match vehicle
uphill direction (i.e., vehicle facing uphill
is in forward gear; vehicle backing uphill is
in REVERSE (R) gear).
HSA will work in REVERSE gear and all
forward gears. The system will not activate
if the transmission is in PARK (P) or
NEUTRAL (N). For vehicles equipped with
a manual transmission, if the clutch is
pressed, HSA will remain active.
Disabling And Enabling HSA
This feature can be turned on or turned off.
To change the current setting, proceed as
follows:
If disabling HSA using your instrument
cluster display, refer to “Instrument
Cluster Display” in “Getting To Know Your
Instrument Panel” for further information.
If disabling HSA using Uconnect Settings,
refer to “Uconnect Settings” in “Multi-
media” for further information.
For vehicles not equipped with an instru -
ment cluster display, perform the following
steps:
1. Center the steering wheel (front wheels pointing straight forward)
2. Shift the transmission into PARK (P)
3. Apply the park brake
4. Start the engine 5. Rotate the steering wheel slightly more
than one-half turn to the left
6. Push the “ESC OFF” button located in the lower switch bank below the climate
control four times within 20 seconds.
The “ESC Off Indicator Light” should
turn on and turn off two times
7. Rotate the steering wheel back to center and then an additional slightly more than
one-half turn to the right
8. Turn the ignition to the OFF mode and then back to ON. If the sequence was
completed properly, the “ESC Off Indi -
cator Light” will blink several times to
confirm HSA is disabled
9. Repeat these steps if you want to return this feature to its previous setting
WARNING!
There may be situations where the Hill
Start Assist (HSA) will not activate and
slight rolling may occur, such as on minor
hills or with a loaded vehicle, or while
pulling a trailer. HSA is not a substitute for
active driving involvement. It is always the
driver’s responsibility to be attentive to
distance to other vehicles, people, and
objects, and most importantly brake
operation to ensure safe operation of the
vehicle under all road conditions. Your
complete attention is always required
while driving to maintain safe control of
your vehicle. Failure to follow these
warnings can result in a collision or serious
personal injury.

Traction Control System (TCS)
The Traction Control System (TCS) monitors
the amount of wheel spin of each of the
driven wheels. If wheel spin is detected, the
TCS may apply brake pressure to the spin-
ning wheel(s) and/or reduce engine power to
provide enhanced acceleration and stability.
A feature of the TCS, Brake Limited Differen -
tial (BLD), functions similar to a limited slip
differential and controls the wheel spin
across a driven axle. If one wheel on a driven
axle is spinning faster than the other, the
system will apply the brake of the spinning
wheel. This will allow more engine torque to
be applied to the wheel that is not spinning.
BLD may remain enabled even if TCS and
Electronic Stability Control (ESC) are in a
reduced mode.
Trailer Sway Control (TSC)
Trailer Sway Control (TSC) uses sensors in
the vehicle to recognize an excessively
swaying trailer and will take the appropriate
actions to attempt to stop the sway. TSC will
become active automatically once an exces -
sively swaying trailer is recognized. NOTE:
TSC cannot stop all trailers from swaying.
Always use caution when towing a trailer and
follow the trailer tongue weight recommen
-
dations. Refer to “Trailer Towing” in
“Starting And Operating” for further informa -
tion.
When TSC is functioning, the “ESC Activa -
tion/Malfunction Indicator Light” will flash,
the engine power may be reduced and you
may feel the brakes being applied to indi -
vidual wheels to attempt to stop the trailer
from swaying. TSC is disabled when the ESC
system is in the “Partial Off” or “Full Off”
modes.
AUXILIARY DRIVING
SYSTEMS
Blind Spot Monitoring (BSM) — If
Equipped
The Blind Spot Monitoring (BSM) system
uses two radar-based sensors, located inside
the rear bumper fascia, to detect highway
licensable vehicles (automobiles, trucks,
motorcycles, etc.) that enter the blind spot
zones from the rear/front/side of the vehicle.
Rear Detection Zones
When the vehicle is started, the BSM
warning light will momentarily illuminate in
both outside rear view mirrors to let the
driver know that the system is operational.
WARNING!
If TSC activates while driving, slow the
vehicle down, stop at the nearest safe
location, and adjust the trailer load to
eliminate trailer sway.
2020_JEEP_CHEROKEE_UG_RHD_UK.book Page 87

SAFETY
88
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
Vehicles that move into your adjacent lanes
from either side of the vehicle.
2020_JEEP_CHEROKEE_UG_RHD_UK.book Page 88

89
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.

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

(Continued)
The tire pressure will vary with temperature
by approximately 1 psi (7 kPa) for every 12°F
(6.5°C). This means that when the outside
temperature decreases, the tire pressure will
decrease. Tire pressure should always be set
based on cold inflation tire pressure. This is
defined as the tire pressure after the vehicle
has not been driven for at least three hours,
or driven less than 1 mile (1.6 km) after a
three hour period. The cold tire inflation
pressure must not exceed the maximum
inflation pressure molded into the tire side-
wall. The tire pressure will also increase as
the vehicle is driven. This is normal and
there should be no adjustment for this
increased pressure.
Refer to “Tires” in “Servicing And Mainte -
nance” for information on how to properly
inflate the vehicle’s tires.
The TPMS will warn the driver of a low tire
pressure if the tire pressure falls below the
low-pressure warning limit for any reason,
including low temperature effects and
natural pressure loss through the tire.
The TPMS will continue to warn the driver of
low tire pressure as long as the condition
exists, and will not turn off until the tire pres -
sure is at or above the recommended cold placard pressure. Once the low tire pressure
warning (Tire Pressure Monitoring Telltale
Light) illuminates, you must increase the tire
pressure to the recommended cold placard
pressure in order for the “Tire Pressure Moni
-
toring Telltale Light” to turn off.
The system will automatically update and
the “Tire Pressure Monitoring Telltale Light”
will turn off once the system receives the
updated tire pressures. 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.

For example, your vehicle may have a recom -
mended cold (parked for more than three
hours) placard pressure of 33 psi (227 kPa). If
the ambient temperature is 68°F (20°C) and
the measured tire pressure is 28 psi (193 kPa),
a temperature drop to 20°F (-7°C) will decrease
the tire pressure to approximately 24 psi (165
kPa). This tire pressure is low enough to turn on
the “Tire Pressure Monitoring Telltale Light.”
Driving the vehicle may cause the tire pressure
to rise to approximately 28 psi (193 kPa), but
the “Tire Pressure Monitoring Telltale Light”
will still be on. In this situation, the “Tire Pres -
sure Monitoring Telltale Light” will turn off only
after the tires are inflated to the vehicle’s
recommended cold placard pressure value.
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 Telltale Light off.
CAUTION!

The TPMS has been optimized for the orig
-
inal equipment tires and wheels. TPMS
pressures and warning have been estab -
lished for the tire size equipped on your
vehicle. Undesirable system operation or
sensor damage may result when using
replacement equipment that is not of the
same size, type, and/or style. The TPM
sensor is not designed for use on after -
market wheels, and may contribute to a
poor overall system performance.
Customers are encouraged to use OEM
wheels to assure TPMS feature operation.

Using aftermarket tire sealants may
cause the Tire Pressure Monitoring
System (TPMS) sensor to become inop -
erable. After using an aftermarket tire
sealant it is recommended that you take
your vehicle to an authorized dealer to
have your sensor function checked.
2020_JEEP_CHEROKEE_UG_RHD_UK.book Page 94

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)

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.

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
