2023 JEEP GRAND CHEROKEE warning lights

258SAFETY
AUXILIARY DRIVING SYSTEMS
BLIND SPOT MONITORING (BSM)
BSM system uses two radar sensors, located
inside the rear fascia/bumper, 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
rearview mirrors to let the driver know that the
system is operational. The BSM system sensors
operate when the vehicle is in any forward gear. The BSM detection zone covers approximately one
lane in width on both sides of the vehicle 12 ft
(3.8 m). The zone length starts at the side of the
vehicle, near the B-pillar, and extends
approximately 10 ft (3 m) beyond the rear fascia/
bumper of the vehicle. The BSM system monitors
the detection zones on both sides of the vehicle
when the vehicle speed reaches approximately
6 mph (10 km/h) or higher and will alert the driver
of vehicles in these areas. BSM will alert earlier on
faster-approaching vehicles — up to 33 mph
(54 km/h) difference.
NOTE: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
equipment) extends beyond the side of your
vehicle, this may result in random false detections
on the trailer, and false chimes when the turn
signal is used Ú
page 204. The BSM system can become blocked if snow, ice,
mud, or other road contaminations accumulate on
the rear fascia/bumper where the radar sensors
are located. The system may also detect blockage
if the vehicle is operated in areas with extremely
low radar returns such as a desert or parallel to a
large elevation drop. If blockage is detected, a
“Blind Spot Temporarily Unavailable, Sensor
Blocked” message will display in the cluster, both
mirror lights will illuminate, and BSM and RCP
alerts will not occur. This is normal operation. The
system will automatically recover and resume
function when the condition clears or when an
ignition cycle occurs. To minimize system
blockage, do not block the area of the rear fascia/
bumper where the radar sensors are located with
foreign objects (bumper stickers, bicycle racks,
etc.) and keep it clear of road contaminations.

260SAFETY

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 Ú page 408.

Opposing Traffic

Rear Cross Path (RCP)
RCP 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 Detection Zones

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 5 mph (8 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 (Blind Spot Lights Only or Blind
Spot Lights/Chimes) and the vehicle is in
REVERSE, the driver is alerted using both the
visual and audible alarms, including reducing the
radio volume.
Blind Spot Modes
Three selectable modes of operation are available
in the Uconnect system Ú page 204.
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 (RCP) Detection is not a back up
aid system. It is intended to be used to help a
driver detect a 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.

SAFETY261
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
object are 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 operating
mode when the vehicle is shut off. Each time the
vehicle is started, the previously stored mode will
be recalled and used.
FORWARD COLLISION WARNING (FCW)
W
ITH MITIGATION
The FCW with Mitigation system provides the driver
with audible warnings, visual warnings (within the
instrument cluster display), and may apply a
limited braking to warn the driver when it detects a
potential frontal collision. The warnings and limited
braking are intended to provide the driver with
enough time to react, avoid or mitigate the
potential collision.
NOTE:If either FCW or Pedestrian Emergency Braking
(PEB) is turned off, the FCW OFF Indicator Light will
illuminate. The FCW OFF Indicator Light will only
shut off if both features are turned on and active
braking is enabled.
NOTE:FCW monitors the information from the forward
looking sensors as well as the Electronic Brake
Controller (EBC), to calculate the probability of a
forward collision. When the system determines
that a forward collision is probable, the driver will
be provided with audible and visual warnings and
may provide a brake jerk warning. 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 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.

268SAFETY
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
TPMS sensors. Then, drive the vehicle for up to
20 minutes above 15 mph (24 km/h). The TPMS
will chime, the TPMS Warning Light will flash on
and off for 75 seconds and then turn off. The
instrument cluster will display the “SERVICE TPM
SYSTEM” message and then display pressure
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.
Tire Fill Alert
This feature notifies the user when the placard tire
pressure is attained while inflating or deflating the
tire.
The customer may choose to disable or enable the
Tire Fill Alert feature in the apps menu of the
Uconnect system.
NOTE:
The Tire Fill Alert system will only support
inflating or deflating one tire at a time. The user
is required to wait until the hazard lights STOP flashing or 26-30 seconds after the desired
pressure is achieved in one wheel before
switching to another.
The Tire Fill Alert feature cannot be entered if an
existing TPMS fault is set to “active” or if the
system is in deactivation mode (if equipped).
The system will be activated when the system
detects an increase in tire pressure while filling the
tire. The ignition must be in the ON/RUN mode with
the transmission in PARK for vehicles equipped
with an automatic transmission. For vehicles
equipped with a manual transmission, the parking
brake must be applied.
NOTE:It is not required to have the engine running to
enter Tire Fill Alert mode.
The hazard lamps will come on to confirm the
vehicle is in Tire Fill Alert mode. If the hazard lamps
do not come on while inflating the tire, the Tire
Pressure Monitoring System sensor may be in an
inoperative position, preventing the TPMS sensor
signal from being received. In this case, the vehicle
may need to be moved slightly forward or
backward.
When Tire Fill Alert mode is entered, the tire
pressure display screen will be displayed in the
instrument cluster. Operation:
The horn will chirp once to let the user know
when to stop filling the tire, when it reaches
recommended pressure.
The horn will chirp three times if the tire is over
-
filled and will continue to chirp every five
seconds if the user continues to inflate the tire.
The horn will chirp once again when enough air
is let out to reach proper inflation level.
The horn will also chirp three times if the tire is
then underinflated and will continue to chirp
every five seconds if the user continues to
deflate the tire.
Selectable Tire Fill Alert (STFA) —
If Equipped
The Selectable Tire Fill Alert (STFA) system is an
optional feature that is included as part of the
normal Tire Fill Alert system. The system is
designed to allow you to select a pressure to inflate
or deflate the vehicle's front and rear axle tires to,
and to provide feedback while inflating or deflating
the vehicle's tires.

Knee Impact Bolsters
The Knee Impact Bolsters help protect the knees
of the driver and front passenger, and position the
front occupants for improved interaction with the
front air bags.
Supplemental Driver And Front Passenger
Knee Air Bags
This vehicle is equipped with a Supplemental
Driver Knee Air Bag mounted in the instrument
panel below the steering column and a
Supplemental Passenger Knee Air Bag mounted in
the instrument panel below the glove
compartment. The Supplemental Knee Air Bags
provide enhanced protection during a frontal
impact by working together with the seat belts,
pretensioners, and front air bags.
Supplemental Side Air Bags
Supplemental Seat-Mounted Side Air Bags (SABs)
This vehicle is equipped with Supplemental
Seat-Mounted Side Air Bags (SABs). Supplemental Seat-Mounted Side Air Bags (SABs)
are located in the outboard side of the front seats.
The SABs are marked with “SRS AIRBAG” or
“AIRBAG” on a label or on the seat trim on the
outboard side of the seats.
The SABs may help to reduce the risk of occupant
injury during certain side impacts, in addition to
the injury reduction potential provided by the seat
belts and body structure.

Front Supplemental Seat-Mounted Side Air Bag Label

When the SAB deploys, it opens the seam on the
outboard side of the seatback’s trim cover. The
inflating SAB deploys through the seat seam into
the space between the occupant and the door. The
SAB moves at a very high speed and with such a
high force that it could injure occupants if they are
not seated properly, or if items are positioned in
the area where the SAB inflates. Children are at an
even greater risk of injury from a deploying air bag. Supplemental Side Air Bag Inflatable Curtains
(SABICs)
This vehicle is equipped with Supplemental Side
Air Bag Inflatable Curtains (SABICs).
Supplemental Side Air Bag Inflatable Curtains
(SABICs) are located above the side windows. The
trim covering the SABICs is labeled “SRS AIRBAG”
or “AIRBAG.”

WARNING!
Do not drill, cut, or tamper with the knee
impact bolsters in any way.
Do not mount any accessories to the knee
impact bolsters such as alarm lights, stereos,
citizen band radios, etc.
WARNING!
Do not use accessory seat covers or place
objects between you and the Side Air Bags; the
performance could be adversely affected and/or
objects could be pushed into you, causing
serious injury.

23_WL_OM_EN_USC_t.book Page 284

SAFETY287
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
irritation, move to fresh air. If the irritation
continues, see your doctor. If these particles
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 deploy -
ment.
After any collision, the vehicle should be taken
to an authorized dealer immediately.
Enhanced Accident Response System
In the event of an impact, if the communication
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
Your vehicle may also be designed to perform any
of these other functions in response to the
Enhanced Accident Response System:
Turn off the Fuel Filter Heater, Turn off the HVAC

PERIODIC SAFETY CHECKS YOU SHOULD
M
AKE OUTSIDE THE VEHICLE
Tires
Examine tires for excessive tread wear and uneven
wear patterns. Check for stones, nails, glass, or
other objects lodged in the tread or sidewall.
Inspect the tread for cuts and cracks. Inspect
sidewalls for cuts, cracks, and bulges. Check the
lug nut/bolt torque for tightness. Check the tires
(including spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake
lights and exterior lights while you work the
controls. Check turn signal and high beam
indicator lights on the instrument panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under the vehicle after overnight
parking for fuel, coolant, oil, or other fluid leaks.
Also, if gasoline fumes are detected or if fuel or
brake fluid leaks are suspected, the cause should
be located and corrected immediately.
EXHAUST GAS
NEVER place any objects under the floor mat
(e.g., towels, keys, etc.). These objects could
change the position of the floor mat and may
cause interference with the accelerator,
brake, or clutch pedals.
If the vehicle carpet has been removed and
re-installed, always properly attach carpet to
the floor and check the floor mat fasteners are
secure to the vehicle carpet. Fully depress
each pedal to check for interference with the
accelerator, brake, or clutch pedals then
re-install the floor mats.
It is recommended to only use mild soap and
water to clean your floor mats. After cleaning,
always check your floor mat has been properly
installed and is secured to your vehicle using
the floor mat fasteners by lightly pulling mat.
WARNING!
WARNING!
Exhaust gases can injure or kill. They contain
carbon monoxide (CO), which is colorless and
odorless. Breathing it can make you
unconscious and can eventually poison you. To
avoid breathing (CO), follow these safety tips:
Do not run the engine in a closed garage or in
confined areas any longer than needed to
move your vehicle in or out of the area.
If you are required to drive with the trunk/lift -
gate/rear doors open, make sure that all
windows are closed and the climate control
BLOWER switch is set at high speed. DO NOT

IN CASE OF EMERGENCY309
(Continued)
SOS Call System Limitations
Vehicles sold in Mexico
DO NOT have SOS Call
system capabilities.
SOS or other emergency line operators in Mexico
may not answer or respond to SOS system calls.
If the SOS Call system detects a malfunction, any
of the following may occur at the time the
malfunction is detected, and at the beginning of
each ignition cycle:
The overhead console lights located within the
ASSIST and SOS buttons will continuously illumi -
nate red.
The Device Screen will display the following
message “Vehicle device requires service.
Please contact an authorized dealer.”
An In-Vehicle Audio message will state “Vehicle
device requires service. Please contact an
authorized dealer.”
Even if the SOS Call system is fully functional, factors
beyond FCA US LLC’s control may prevent or stop the
SOS Call system operation. These include, but are not
limited to, the following factors:

The ignition is in the OFF position
The vehicle’s electrical systems are not intact
The SOS Call system software and/or hardware
are damaged during a crash
The vehicle battery loses power or becomes
disconnected during a vehicle crash
LTE (voice/data) or 4G (data) network and/or
Global Positioning Satellite signals are unavail
-
able or obstructed

Equipment malfunction at the SOS operator facility

Operator error by the SOS operator

LTE (voice/data) or 4G (data) network congestion

Weather
Buildings, structures, geographic terrain, or
tunnels
Never place anything on or near the vehicle’s
operable network and GPS antennas. You
could prevent operable network and GPS
signal reception, which can prevent your
vehicle from placing an emergency call. An
operable network and GPS signal reception is
required for the SOS Call system to function
properly.
The SOS Call system is embedded into the
vehicle’s electrical system. Do not add after -
market electrical equipment to the vehicle’s
electrical system. This may prevent your
vehicle from sending a signal to initiate an
emergency call. To avoid interference that can
cause the SOS Call system to fail, never add
aftermarket equipment (e.g., two-way mobile
radio, CB radio, data recorder, etc.) to your
vehicle’s electrical system or modify the
antennas on your vehicle. IF YOUR VEHICLE
LOSES BATTERY POWER FOR ANY REASON
(INCLUDING DURING OR AFTER AN ACCI -
DENT), THE JEEP® CONNECT FEATURES,
APPS AND SERVICES, AMONG OTHERS, WILL
NOT OPERATE.
Modifications to any part of the SOS Call
system could cause the air bag system to fail
when you need it. You could be injured if the
air bag system is not there to help protect you.
WARNING!
WARNING!
Ignoring the overhead console light could
mean you will not have SOS Call services. If
the overhead console light is illuminated, have
an authorized dealer service the SOS Call
system immediately.

The Occupant Restraint Control module turns on
the air bag Warning Light on the instrument panel
if a malfunction in any part of the system is
detected. If the Air Bag Warning Light is illumi -
nated, have an authorized dealer service the
Occupant Restraint Control system immediately.
