— AdBlue® Injection System Failure
Warning Light — If Equipped
This warning light will illuminate along with
a dedicated message on the display (If
Equipped) if an unknown fluid not
conforming with acceptable characteristics
is inserted, or if an average consumption of
AdBlue® over 50% is detected. Contact an
authorized dealer as soon as possible.
If the problem is not solved, a specific
message will appear on the Instrument
Cluster Display whenever a certain threshold
is reached until it will no longer be possible
to start the engine. When about 125 miles (200 km) are
remaining before the AdBlue® tank is
empty, a continuous dedicated message will
appear on the instrument panel, accompa
-
nied by a buzzer sound (If Equipped).
— Service 4WD Warning Light — If
Equipped

This warning light will illuminate to signal a
fault with the 4WD system. If the light stays on
or comes on during driving, it means that the
4WD system is not functioning properly and
that service is required. It is recommended you
drive to the nearest service center and have the
vehicle serviced immediately.

— Service Forward Collision Warning
(FCW) Light — If Equipped
This warning light will illuminate to indicate
a fault in the Forward Collision Warning
System. Contact an authorized dealer for
service.
Refer to "Forward Collision Warning (FCW)"
in "Safety" for further information.
— Service Stop/Start System Warning
Light — If Equipped
This warning light will illuminate when the
Stop/Start system is not functioning properly
and service is required. Contact an autho -
rized dealer for service.
— Speed Control Fault Warning Light
This warning light will illuminate to indicate
the Speed Control System is not functioning
properly and service is required. Contact an
authorized dealer.
— Sway Bar Fault Warning Light
This light will illuminate when there is a fault
in the sway bar disconnect system.
— Tire Pressure Monitoring System
(TPMS) Warning Light
The warning light switches on and a message
is displayed to indicate that the tire pressure
is lower than the recommended value and/or
that slow pressure loss is occurring. In these
cases, optimal tire duration and fuel
consumption may not be guaranteed.
CAUTION!
Prolonged driving with the Malfunction
Indicator Light (MIL) on could cause
damage to the vehicle control system. It
also could affect fuel economy and
driveability. If the MIL is flashing, severe
catalytic converter damage and power loss
will soon occur. Immediate service is
required.

Should one or more tires be in the condition
mentioned above, the display will show the
indications corresponding to each tire.
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure
label. If your vehicle has tires of a different
size than the size indicated on the vehicle
placard or tire inflation pressure label, you
should determine the proper tire inflation
pressure for those tires.
As an added safety feature, your vehicle has
been equipped with a Tire Pressure Moni -
toring System (TPMS) that illuminates a low
tire pressure telltale when one or more of
your tires is significantly under-inflated.
Accordingly, when the low tire pressure tell -tale illuminates, you should stop and check
your tires as soon as possible, and inflate
them to the proper pressure. Driving on a
significantly under-inflated tire causes the
tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency
and tire tread life, and may affect the
vehicle’s handling and stopping ability.
Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the
driver’s responsibility to maintain correct tire
pressure, even if under-inflation has not
reached the level to trigger illumination of
the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is
combined with the low tire pressure telltale.
When the system detects a malfunction, the
telltale will flash for approximately one
minute and then remain continuously illumi
-
nated. This sequence will continue upon
subsequent vehicle start-ups as long as the
malfunction exists. When the malfunction
indicator is illuminated, the system may not
be able to detect or signal low tire pressure
as intended. TPMS malfunctions may occur
for a variety of reasons, including the instal -lation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replacing
one or more tires or wheels on your vehicle to
ensure that the replacement or alternate
tires and wheels allow the TPMS to continue
to function properly.
CAUTION!
Do not continue driving with one or more
flat tires as handling may be
compromised. Stop the vehicle, avoiding
sharp braking and steering. If a tire
puncture occurs, repair immediately using
the dedicated tire repair kit and contact an
authorized dealer as soon as possible.
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.

FCW Limited Warning
If the instrument cluster displays “ACC/FCW
Limited Functionality” or “ACC/FCW Limited
Functionality Clean Front Windshield”
momentarily, there may be a condition that
limits FCW functionality. Although the
vehicle is still drivable under normal condi-
tions, the active braking may not be fully
available. Once the condition that limited
the system performance is no longer present,
the system will return to its full performance
state. If the problem persists, see an autho -
rized dealer.
Service FCW Warning
If the system turns off, and the instrument
cluster displays:
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.
FCW Sensor Protective Cover
Your vehicle is equipped with a protective
cover that is to be used whenever the wind -
shield is folded down in order to protect the
FCW sensor. To install the cover, follow the
instructions below.
1. Secure the top part of the cover so that it hinges to the header.
2. Swing the cover down and push on it so that it covers the opening.
3. Check to make sure the cover is secured properly.
NOTE:
Be sure to remove the cover before returning
the windshield to the normal position. Store
the cover in the cargo area.
Cleaning Instructions
During windshield down applications, dust/
dirt can accumulate in the cover and block
the camera lens. Use a microfiber cloth to
clean the camera lens, module, and inside
cover, being careful not to damage or scratch
the module.
Tire Pressure Monitoring System (TPMS)
The Tire Pressure Monitoring System (TPMS)
will warn the driver of a low tire pressure
based on the vehicle recommended cold
placard pressure.
NOTE:
The alert warning on the cluster will stay
on until the tire is inflated to the placard
pressure.
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,
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. Refer to “Tires” in “Servicing And
2020_JEEP_JL_WRANGLER_UG_RHD_UK.book Page 92

93
Maintenance” for information on how to
properly inflate the vehicle’s tires. The tire
pressure will also increase as the vehicle is
driven. This is normal and there should be no
adjustment for this increased pressure.
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 System
Warning Light) illuminates, you must
increase the tire pressure to the recom -
mended cold placard pressure in order for
the TPMS Light to turn off.
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
placard pressure in order to turn the TPMS
Warning Light off.
The system will automatically update and the
TPMS Warning 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
recommended 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 TPMS
Warning Light. Driving the vehicle may
cause the tire pressure to rise to approxi -
mately 28 psi (193 kPa), but the TPMS
Warning Light will still be on. In this situa -
tion, the TPMS Warning Light will turn off
only after the tires are inflated to the
vehicle’s recommended cold placard pres -
sure value. 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 Original
Equipment Manufacturer (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.
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.
2020_JEEP_JL_WRANGLER_UG_RHD_UK.book Page 93

SAFETY
94
NOTE:

The TPMS is not intended to replace normal
tire care and maintenance, or to provide
warning of a tire failure or condition.

The TPMS should not be used as a tire
pressure gauge while adjusting your tire
pressure.
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
responsibility to maintain correct tire pres-
sure using an accurate tire pressure
gauge, even if underinflation has not
reached the level to trigger illumination of
the TPMS Warning Light.
Seasonal temperature changes will affect
tire pressure, and the TPMS will monitor
the actual tire pressure in the tire.
System Operation
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.Tire Pressure Monitoring Display
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 telltale light
Tire Pressure Monitoring Low Pressure Warnings
The TPMS Warning Light will illu -
minate 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.
2020_JEEP_JL_WRANGLER_UG_RHD_UK.book Page 94

95

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 TPMS Warning
Light will turn off. 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
placard pressure in order to turn the TPMS
Warning Light 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.
Service TPMS Warning
When a system fault is detected, the TPMS
Warning Light will flash on and off for 75
seconds and then remain on solid. The
system fault will also sound a chime. In addi
-
tion, the instrument cluster will display a
"SERVICE TIRE PRESSURE SYSTEM"
message for a minimum of five seconds and
then display dashes (--) in place of the pres -
sure value to indicate which sensor is not
being received. If the ignition is cycled, this sequence will
repeat, providing the system fault still exists.
If the system fault no longer exists, the
TPMS Warning Light will no longer flash, and
the “SERVICE TIRE PRESSURE SYSTEM”
message will no longer display, and a pres
-
sure 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

SAFETY
96
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.
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 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 Pressure
System” message for five seconds and
then display dashes (--) in place of the
pressure value. 4. For each subsequent ignition cycle, a
chime will sound, the TPMS Warning
Light will flash on and off for 75 seconds
and then remain on solid, and the instru -
ment cluster will display a “SERVICE
TIRE PRESSURE 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. Vehicles With a Full Size Matching Spare
1. If your vehicle is equipped with a
matching full-size spare wheel and tire
assembly, it has a tire pressure moni -
toring sensor, and can be monitored by
the Tire Pressure Monitoring System
(TPMS) when swapped with a low pres -
sure road tire.
2. In the event that the matching full-size spare tire is swapped with a low pressure
road tire, the next ignition switch cycle
will still show the TPMS Warning Light to
be on, a chime to sound, and the graphic
display will still show the low tire pres -
sure value in a different color.
3. Driving the vehicle for up to 10 minutes above 15 mph (24 km/h) will turn off theTPMS Warning Light as long as none of
road tires are below the low pressure
warning threshold.
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.
2020_JEEP_JL_WRANGLER_UG_RHD_UK.book Page 96

97

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 TPMS Warning Light will flash on and off for
75 seconds and then remain on. The instrument
cluster will display the “SERVICE TIRE PRES-
SURE 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
TIRE PRESSURE 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 10 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 instru -
ment cluster will display the “SERVICE TIRE
PRESSURE SYSTEM” message and then
display pressure values in place of the
dashes. On the next ignition cycle the
"SERVICE TIRE PRESSURE 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
