Yellow Indicator Lights — Active Speed Limiter Fault Indicator
Light — If Equipped
This warning light will illuminate to signal
when there is a fault detected with the Active
Speed Limiter.
— Forward Collision Warning Off
Indicator Light — If Equipped
This light indicates that Forward Collision
Warning is off.
— 4WD Low Indicator Light — If
Equipped
This light alerts the driver that the vehicle is
in the four-wheel drive LOW mode. The front
and rear driveshafts are mechanically locked
together forcing the front and rear wheels to
rotate at the same speed. Low range provides
a greater gear reduction ratio to provide
increased torque at the wheels.
Refer to “Four-Wheel Drive Operation” in
“Starting And Operating” for further informa -
tion on four-wheel drive operation and proper
use.
— Rear Axle Lock Indicator Light
This light indicates when the rear axle lock
has been activated.
— Rear Fog Indicator — If Equipped
This indicator light will illuminate when the
rear fog lights are on.
— Glow Plug Light — If Equipped
This vehicle will inhibit engine cranking
when the ambient temperature is less than
–22° F (–30° C) and the oil temperature
sensor reading indicates an engine block
heater has not been used. The Glow Plug
light will flash during in cold weather for up
to ten seconds.
If equipped with a block heater harness the
message “Plug In Engine Heater”, will be
displayed in the instrument cluster when the
ambient temperature is below 5°F (-15° C) at
the time the engine is shut off as a reminder
to avoid possible crank delays at the next
cold start.
CAUTION!
The TPMS has been optimized for the
original equipment tires and wheels.
TPMS pressures and warning have been
established 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. Aftermarket
wheels can cause sensor damage. Using
aftermarket tire sealants may cause the
Tire Pressure Monitoring System (TPMS)
sensor to become inoperable. After using
an aftermarket tire sealant it is
recommended that you take your vehicle to
an authorized dealer to have your sensor
function checked.

Anti-Lock Brake Warning Light
The yellow “Anti-Lock Brake Warning Light”
will turn on when the ignition is cycled to the
ON/RUN mode and may stay on for as long
as four seconds.
If the “Anti-Lock Brake Warning Light”
remains on or comes on while driving, it indi-
cates that the anti-lock portion of the brake
system is not functioning and that service is
required. However, the conventional brake
system will continue to operate normally if
the “Anti-Lock Brake Warning Light” is on.
If the “Anti-Lock Brake Warning Light” is on,
the brake system should be serviced as soon
as possible to restore the benefits of
anti-lock brakes. If the “Anti-Lock Brake
Warning Light” does not come on when the
ignition is cycled to the ON/RUN mode, have
the light repaired as soon as possible.
Electronic Brake Control (EBC) System

Your vehicle is equipped with an advanced
Electronic Brake Control (EBC) system. This
system includes Electronic Brake Force Distri -
bution (EBD), Anti-Lock Brake System (ABS),
Brake Assist System (BAS), Hill Start Assist
(HSA), Traction Control System (TCS), Elec-
tronic Stability Control (ESC), and Electronic Roll Mitigation (ERM). These systems work
together to enhance both vehicle stability and
control in various driving conditions.

Your vehicle may also be equipped with
Trailer Sway Control (TSC), Ready Alert
Braking (RAB), Rain Brake Support (RBS),
Dynamic Steering Torque (DST), Hill
Descent Control (HDC), and Selec-Speed
Control (SSC).
Brake System Warning Light
The red “Brake System Warning Light” will
turn on when the ignition is placed in the
ON/RUN mode and may stay on for as long
as four seconds.
If the “Brake System Warning Light”
remains on or comes on while driving, it indi
-
cates that the brake system is not func -
tioning properly and that immediate service
is required. If the “Brake System Warning
Light” does not come on when the ignition is
turned to the ON/RUN mode, have the light
repaired as soon as possible.
Brake Assist System (BAS)
The Brake Assist System (BAS) is designed
to optimize the vehicle’s braking capability
during emergency braking maneuvers. The system detects an emergency braking situa
-
tion by sensing the rate and amount of brake
application and then applies optimum pres -
sure to the brakes. This can help reduce
braking distances. The BAS complements
the Anti-Lock Brake System (ABS). Applying
the brakes very quickly results in the best
BAS assistance. To receive the benefit of the
system, you must apply continuous braking
pressure during the stopping sequence, (do
not “pump” the brakes). Do not reduce brake
pedal pressure unless braking is no longer
desired. Once the brake pedal is released,
the BAS is deactivated.
WARNING!
The Brake Assist System (BAS) cannot
prevent the natural laws of physics from
acting on the vehicle, nor can it increase
the traction afforded by prevailing road
conditions. BAS cannot prevent collisions,
including those resulting from excessive
speed in turns, driving on very slippery
surfaces, or hydroplaning. The capabilities
of a BAS-equipped vehicle must never be
exploited in a reckless or dangerous
manner, which could jeopardize the user's
safety or the safety of others.

ESC Operating Modes
NOTE:
Depending upon model and mode of opera-
tion, the ESC system may have multiple
operating modes.
ESC On
This is the normal operating mode for the
ESC. Whenever the vehicle is started, the
ESC system will be in this mode. This mode
should be used for most driving conditions.
Alternate ESC modes should only be used for
specific reasons as noted in the following
paragraphs.
Partial Off
The “Partial Off” mode is intended for times
when a more spirited driving experience is
desired. This mode may modify TCS and ESC
thresholds for activation, which allows for
more wheel spin than normally allowed. This
mode may be useful if the vehicle becomes
stuck.
To enter the “Partial Off” mode, momentarily
push the “ESC OFF” switch and the “ESC
OFF Indicator Light” will illuminate. To turn
the ESC on again, momentarily push the
“ESC OFF” switch and the “ESC OFF Indi -
cator Light” will turn off. NOTE:
For vehicles with multiple partial ESC modes
a momentary button push will toggle the ESC
mode. Multiple momentary button pushed
may be required to return to ESC On.
Full Off — If Equipped
This mode is intended for off-highway or
off-road use only and should not be used on
any public roadways. In this mode, TCS and
ESC features are turned off. To enter the
“Full Off” mode, push and hold the “ESC
OFF” switch for five seconds while the
vehicle is stopped with the engine running.
After five seconds, a chime will sound, the
“ESC Off Indicator Light” will illuminate,
and the “ESC OFF” message will display in
the instrument cluster. To turn ESC on
again, momentarily push the “ESC OFF”
switch.
NOTE:
System may switch from ESC “Full Off” to
“Partial Off” mode when vehicle exceeds a
predetermined speed. When the vehicle
speed slows below the predetermined speed
the system will return to ESC “Full Off”.
ESC modes may also be affected by drive
modes (if equipped).
WARNING!
When in “Partial Off” mode, the TCS
functionality of ESC, (except for the
limited slip feature described in the TCS
section), has been disabled and the
“ESC Off Indicator Light” will be illumi
-
nated. When in “Partial Off” mode, the
engine power reduction feature of TCS is
disabled, and the enhanced vehicle
stability offered by the ESC system is
reduced.
Trailer Sway control (TSC) is disabled
when the ESC system is in the “Partial
Off” mode.
WARNING!

In the ESC “Full Off” mode, the engine
torque reduction and stability features are
disabled. Therefore, enhanced vehicle
stability offered by the ESC system is
unavailable. In an emergency evasive
maneuver, the ESC system will not engage
to assist in maintaining stability. ESC “Full
Off” mode is intended for off-highway or
off-road use only.

ESC Activation/Malfunction Indicator Light
And ESC OFF Indicator Light

The “ESC Activation/Malfunction
Indicator Light” in the instrument
cluster will come on when the ignition
is turned to the ON mode. It should
turn off with the engine running. If the “ESC
Activation/Malfunction Indicator Light” comes
on continuously with the engine running, a
malfunction has been detected in the ESC
system. If this light remains on after several
ignition cycles, and the vehicle has been driven
several miles (kilometers) at speeds greater than
30 mph (48 km/h), see an authorized dealer as
soon as possible to have the problem diagnosed
and corrected.
The “ESC Activation/Malfunction Indicator
Light” (located in the instrument cluster)
starts to flash as soon as the tires lose trac
-
tion and the ESC system becomes active.
The “ESC Activation/Malfunction Indicator
Light” also flashes when TCS is active. If the
“ESC Activation/Malfunction Indicator
Light” begins to flash during acceleration,
ease up on the accelerator and apply as little
throttle as possible. Be sure to adapt your
speed and driving to the prevailing road
conditions.
NOTE:
The “ESC Activation/Malfunction Indi -
cator Light” and the “ESC OFF Indicator
Light” come on momentarily each time
the ignition is turned ON.
Each time the ignition is turned ON, the
ESC system will be on even if it was turned
off previously.
The ESC system will make buzzing or
clicking sounds when it is active. This is
normal; the sounds will stop when ESC
becomes inactive following the maneuver
that caused the ESC activation. The “ESC OFF Indicator Light”
indicates the customer has elected
to have the Electronic Stability
Control (ESC) in a reduced mode.
Hill Start Assist (HSA)

The Hill Start Assist (HSA) system is designed
to mitigate roll back from a complete stop while
on an incline. If the driver releases the brake
while stopped on an incline, HSA will continue
to hold the brake pressure for a short period. If
the driver does not apply the throttle before this
time expires, the system will release brake
pressure and the vehicle will roll down the hill
as normal.

The following conditions must be met in
order for HSA to activate:
The feature must be enabled.
The vehicle must be stopped.
The park brake must be off.
The driver door must be closed.
The vehicle must be on a sufficient grade.
The Electronic Stability Control (ESC)
cannot prevent the natural laws of
physics from acting on the vehicle, nor
can it increase the traction afforded by
prevailing road conditions. ESC cannot
prevent all accidents, including those
resulting from excessive speed in turns,
driving on very slippery surfaces, or
hydroplaning. ESC also cannot prevent
collisions.
WARNING! (Continued)

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.

NOTE:
During SSC the +/- shifter input is used for
SSC target speed selection but will not
affect the gear chosen by the transmis-
sion. While actively controlling SSC the
transmission will shift appropriately for
the driver-selected set speed and corre-
sponding driving conditions.

SSC performance is influenced by the
Terrain Select mode. This difference may be
notable to the driver and may be perceived
as a varying level of aggressiveness.
Driver Override:
The driver may override SSC activation with
throttle or brake application at any time.
Deactivating SSC
SSC will be deactivated but remain available
if any of the following conditions occur:
Driver overrides SSC set speed with
throttle or brake application.
Vehicle speed exceeds 20 mph (32 km/h)
but remains below 40 mph (64 km/h).
Vehicle is shifted to PARK.
Disabling SSC
SSC will deactivate and be disabled if any of
the following conditions occur:
The driver pushes the SSC switch
The driveline is shifted out of 4L Range
The park brake is applied
Driver door opens
The vehicle is driven greater than 20 mph
(32 km/h) for greater than 70 seconds
The vehicle is driven greater than 40 mph
(64 km/h) (SSC exits immediately) Feedback To The Driver:
The instrument cluster has an SSC icon and
the SSC switch has an LED which offer feed
-
back to the driver about the state SSC is in.
The cluster icon and switch lamp will illu -
minate and remain on solid when SSC is
enabled or activated. This is the normal
operating condition for SSC.
The cluster icon and switch lamp will flash
for several seconds then extinguish when
the driver pushes the SSC switch but
enable conditions are not met.
The cluster icon and switch lamp will flash
for several seconds then extinguish when
SSC disables due to excess speed.
The cluster icon and switch lamp will flash
then extinguish when SSC deactivates due
to overheated brakes.
WARNING!
SSC is only intended to assist the driver in
controlling vehicle speed when driving in
off road conditions. The driver must
remain attentive to the driving conditions
and is responsible for maintaining a safe
vehicle speed.

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.

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.

back into the retractor. If it is locked, the
ALR will make a clicking noise while the
webbing is pulled back into the retractor.
Refer to the “Automatic Locking Mode”
description in “Switchable Automatic
Locking Retractors (ALR)” under “Occupant
Restraint Systems” for additional informa-
tion on ALR.
Installing A Child Restraint With A
Switchable Automatic Locking Retractor
(ALR)
Child restraint systems are designed to be
secured in vehicle seats by lap belts or the
lap belt portion of a lap/shoulder belt. 1. Place the child seat in the center of the
seating position. For some second row
seats, you may need to recline the seat
and/or raise the head restraint to get a
better fit. If the rear seat can be moved
forward and rearward in the vehicle, you
may wish to move it to its rear-most posi -
tion to make room for the child seat. You
may also move the front seat forward to
allow more room for the child seat.
2. Pull enough of the seat belt webbing from the retractor to pass it through the
belt path of the child restraint. Do not
twist the belt webbing in the belt path.
3. Slide the latch plate into the buckle until you hear a “click.”
4. Pull on the webbing to make the lap portion tight against the child seat. 5. To lock the seat belt, pull down on the
shoulder part of the belt until you have
pulled all the seat belt webbing out of the
retractor. Then, allow the webbing to
retract back into the retractor. As the
webbing retracts, you will hear a clicking
sound. This means the seat belt is now in
the Automatic Locking mode.
6. Try to pull the webbing out of the retractor. If it is locked, you should not
be able to pull out any webbing. If the
retractor is not locked, repeat step 5.
7. Finally, pull up on any excess webbing to tighten the lap portion around the child
restraint while you push the child
restraint rearward and downward into the
vehicle seat.
8. Test that the child restraint is installed tightly by pulling back and forth on the
child seat at the belt path. It should not
move more than 25 mm in any direction.
Any seat belt system will loosen with time, so
check the belt occasionally, and pull it tight
if necessary.
WARNING!
Improper installation or failure to prop -
erly secure a child restraint can lead to
failure of the restraint. The child could
be badly injured or killed.
Follow the child restraint manufacturer’s
directions exactly when installing an
infant or child restraint.
