2019 JEEP CHEROKEE ignition

2. Shift the transmission into PARK.
3. Apply the parking 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 con-
trol 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 Indica-
tor Light” will blink several times to con-
firm HSA is disabled.
9. Repeat these steps if you want to return
this feature to its previous setting.Towing With HSA
HSA will also provide assistance to mitigate
roll back while towing a trailer.
WARNING!
• If you use a trailer brake controller with
your trailer, the trailer brakes may be
activated and deactivated with the brake
switch. If so, there may not be enough
brake pressure to hold both the vehicle
and the trailer on a hill when the brake
pedal is released. In order to avoid roll-
ing down an incline while resuming ac-
celeration, manually activate the trailer
brake or apply more vehicle brake pres-
sure prior to releasing the brake pedal.
• HSA is not a parking brake. Always apply
the parking brake fully when exiting your
vehicle. Also, be certain to place the
transmission in PARK.
• Failure to follow these warnings can re-
sult in a collision or serious personal
injury.
Traction Control System (TCS)
This system 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 spinning wheel(s) and/or re-
duce engine power to provide enhanced ac-
celeration and stability. A feature of the TCS,
Brake Limited Differential (BLD), functions
similar to a limited slip differential and con-
trols 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 en-
abled even if TCS and ESC are in a reduced
mode.
Electronic Stability Control (ESC)
This system enhances directional control and
stability of the vehicle under various driving
conditions. ESC corrects for oversteering or
understeering of the vehicle by applying the
brake of the appropriate wheel(s) to assist in
counteracting the oversteer or understeer
condition. Engine power may also be reduced
to help the vehicle maintain the desired path.
SAFETY
80

WARNING!
maneuver, the ESC system will not en-
gage to assist in maintaining stability.
ESC “Full Off” mode is only intended for
off-highway or off-road use.
• The Electronic Stability Control (ESC)
cannot prevent the natural laws of phys-
ics from acting on the vehicle, nor can it
increase the traction afforded by prevail-
ing 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.
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 go out with the engine
running. If the “ESC Activation/Malfunction
Indicator Light” comes on continuously withthe 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 con-
ditions.
NOTE:
• The “ESC Activation/Malfunction Indicator
Light” and the “ESC OFF Indicator Light”
come on momentarily each time the igni-
tion 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 click-
ing 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” indi-
cates the customer has elected to
have the Electronic Stability Control
(ESC) in a reduced mode.
Electronic Roll Mitigation (ERM)
This system anticipates the potential for
wheel lift by monitoring the driver’s steering
wheel input and the speed of the vehicle.
When ERM determines that the rate of
change of the steering wheel angle and vehi-
cle’s speed are sufficient to potentially cause
wheel lift, it then applies the appropriate
brake and may also reduce engine power to
lessen the chance that wheel lift will occur.
ERM can only reduce the chance of wheel lift
occurring during severe or evasive driving
83

Changing the FCW status to the “Near” set-
ting, allows the system to warn the driver of a
possible collision with the vehicle in front
when the distance between the vehicle in the
front is much closer. This setting provides
less reaction time than the “Far” and “Me-
dium” settings, which allows for a more dy-
namic driving experience.
NOTE:
• Changing the FCW status to “Only Warn-
ing” prevents the system from providing
limited active braking, or additional brake
support if the driver is not braking ad-
equately in the event of a potential frontal
collision, but maintains the audible and
visual warnings.
• Changing the FCW status to “Off” prevents
the system from providing autonomous
braking, or additional brake support if the
driver is not braking adequately in the event
of a potential frontal collision.
• The 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.• 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, oncom-
ing traffic, or leading vehicles with the
same or higher rate of speed.
• FCW will be disabled like ACC, with the
unavailable screens.
FCW Limited Warning
If the instrument cluster display reads “ACC/
FCW Limited Functionality” or “ACC/FCW
Limited Functionality Clean Front Wind-
shield” momentarily, there may be a condi-
tion that limits FCW functionality. Although
the vehicle is still drivable under normal
conditions, the active braking may not be
fully available. Once the condition that lim-
ited the system performance is no longer
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 drivable
under normal conditions, have the system
checked by an authorized dealer.
Pedestrian Emergency Braking (PEB) — If
Equipped
The Pedestrian Emergency Braking (PEB) is a
sub-system of the FCW system which pro-
vides the driver with audible and visual warn-
ings 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).
93

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.
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 “Pedes-
trian Emergency Braking” button once.
To turn the PEB system back on, push the
“Pedestrian Emergency Braking” button
again.Changing the PEB status to “Off” deactivates
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 de-
fault setting when the vehicle is restarted.
Tire Pressure Monitor System (TPMS)
The Tire Pressure Monitor 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.
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, ordriven less than 1 mile (1.6 km) after a three
hour period. The cold tire inflation pressure
must not exceed the maximum inflation pres-
sure molded into the tire sidewall. 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 natu-
ral 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
pressure is at or above the recommended
cold placard pressure. Once the low tire pres-
sure warning (Tire Pressure Monitoring Tell-
tale Light) illuminates, you must increase the
tire pressure to the recommended cold plac-
ard pressure in order for the “Tire Pressure
Monitoring Telltale Light” to turn off.
SAFETY
94

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 4 psi
(28 kPa) above the recommended cold plac-
ard pressure in order to turn the Tire Pressure
Monitoring Telltale Light off.
Service TPMS Warning
When a system fault is detected, the “Tire
Pressure Monitoring Telltale 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" mes-
sage 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 Telltale Light” will
no longer flash, and the “SERVICE TPM SYS-
TEM” message will no longer display, and apressure 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 driv-
ing 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 com-
pact spare tire.
2. If you install the compact or non-
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 TelltaleLight” will remain on and a chime will
sound. In addition, the graphic in the
instrument cluster will still display a dif-
ferent color pressure value.
3. After driving the vehicle for up to 10 min-
utes above 15 mph (24 km/h), the “TPMS
Telltale Light” will flash on and off for
75 seconds and then remain on solid. In
addition, the instrument cluster will dis-
play a “Service Tire Pressure 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 Telltale
Light” will flash on and off for 75 seconds
and then remain on solid, and the instru-
ment 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
Telltale Light” will turn off and the
97

graphic in the instrument cluster will dis-
play 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 Moni-
toring (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 thenremain on. The instrument cluster will dis-
play 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 instrument
cluster will display the “SERVICE TPM SYS-
TEM” 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.OCCUPANT RESTRAINT
SYSTEMS
Some of the most important safety features in
your vehicle are the restraint systems:
Occupant Restraint Systems Features
• Seat Belt Systems
• Supplemental Restraint Systems (SRS) Air
Bags
• Child Restraints
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.
Important Safety Precautions
Please pay close attention to the information
in this section. It tells you how to use your
restraint system properly, to keep you and
your passengers as safe as possible.
SAFETY
98

WARNING!
• 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.
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
injuries 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 fea-
ture 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 turnoff. 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 out-
board 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 BeltAlert warn-
ing sequence has completed, the Seat Belt
Reminder Light will remain solid red until the
driver and outboard front seat passenger are
buckled. The BeltAlert warning sequence
may repeat based on vehicle speed until the
driver and occupied outboard front seat pas-
senger seat belts are buckled. The driver
should instruct all occupants to buckle their
seat belts.
Change Of Status
If the driver or outboard front seat passenger
unbuckles their seat belt while the vehicle is
SAFETY
100

traveling, the BeltAlert warning sequence will
begin until the seat belts are buckled again.
The outboard front passenger seat BeltAlert
is not active when the outboard front passen-
ger seat is unoccupied. BeltAlert may be
triggered when an animal or other items are
placed on the outboard front passenger seat
or when the seat is folded flat (if equipped). It
is recommended that pets be restrained in
the rear seat (if equipped) in pet harnesses or
pet carriers that are secured by seat belts,
and cargo is properly stowed.
Rear Seat BeltAlert
Rear Seat BeltAlert shows the driver whether
the seat belts in the rear seat are buckled or
unbuckled. When the ignition switch is in the
START or ON/RUN position, a Seat Belt Re-
minder Light turns on for each rear seat
position. If a seat belt is buckled, the Seat
Belt Reminder Light for that position will
illuminate solid green. If a seat belt is un-
buckled, the Seat Belt Reminder Light will
illuminate red. If a rear passenger unbuckles
a seat belt that was buckled at the start of the
trip, a single chime will sound and the Seat
Belt Reminder Light for that position willchange from solid green to blinking red. This
will alert the driver to stop the vehicle until
the rear passenger buckles the seat belt
again. After the driver and outboard front seat
passenger have buckled their seat belts all
Seat Belt Reminder Lights will turn off.
BeltAlert can be activated or deactivated by
an authorized dealer. FCA US LLC does not
recommend deactivating BeltAlert.
NOTE:
If BeltAlert has been deactivated, the Seat
Belt Reminder Light will turn on and remain
on until the driver and outboard front seat
passenger seat belts are buckled.
Lap/Shoulder Belts
All seating positions in your vehicle are
equipped with lap/shoulder belts.
The seat belt webbing retractor will lock only
during very sudden stops or collisions. This
feature allows the shoulder part of the seat
belt to move freely with you under normal
conditions. However, in a collision the seat
belt will lock and reduce your risk of striking
the inside of the vehicle or being thrown out
of the vehicle.
WARNING!
• Relying on the air bags alone could lead
to more severe injuries in a collision. The
air bags work with your seat belt to
restrain you properly. In some collisions,
the air bags won’t deploy at all. Always
wear your seat belt even though you have
air bags.
• In a collision, you and your passengers
can suffer much greater injuries if you
are not properly buckled up. You can
strike the interior of your vehicle or other
passengers, or you can be thrown out of
the vehicle. Always be sure you and
others in your vehicle are buckled up
properly.
• It is dangerous to ride in a cargo area,
inside or outside of a vehicle. In a colli-
sion, people riding in these areas are
more likely to be seriously injured or
killed.
• Do not allow people to ride in any area of
your vehicle that is not equipped with
seats and seat belts.
