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. We recommend 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 Colli -
sion Warning (FCW) With Mitigation
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 authorized dealer for
service.
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.
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.
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.

GETTING TO KNOW YOUR INSTRUMENT PANEL
66
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.
Towing Hook Breakdown Warning Light — If
Equipped
This light illuminates when there is
a failure with the tow hook. Contact
an authorized dealer for service.
Yellow Indicator Lights
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 drive -
shafts 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 — If
Equipped” in “Starting And Operating” for
further information on four-wheel drive oper -
ation and proper use.
4WD Lock Indicator Light
This light alerts the driver that the
vehicle is in the four-wheel drive
LOCK mode. The front and rear
driveshafts are mechanically locked
together, forcing the front and rear wheels to
rotate at the same speed.
Refer to “Four-Wheel Drive Operation — If
Equipped” in “Starting And Operating” for
further information on four-wheel drive oper -
ation and proper use.
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.
2020_JEEP_M6_UG_UK.book Page 66

SAFETY
86
Changing the FCW status to the “Near”
setting, 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 “Medium” settings, which allows for a
more dynamic driving experience.
NOTE:
The system will NOT retain the last setting
selected by the driver after ignition shut
down. The system will reset to Medium
sensitivity with FCW "Full On" 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, oncoming traffic, or leading vehicles
with the same or higher rate of speed.
If FCW is disabled, unavailable screens
will be displayed.
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
limited 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 “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.
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.
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
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 pressure is
at or above the recommended cold placard
pressure.
NOTE:
Once the low tire pressure warning (TPMS
Warning Light) illuminates, you must
increase the tire pressure to the recom -
mended cold placard pressure in order for
the TPMS Warning Light to turn off.
2020_JEEP_M6_UG_UK.book Page 86

87
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 pres-
sures. 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 informa -
tion.
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 “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. NOTE:
The TPMS is not intended to replace
normal tire care and maintenance, or to
provide warning of a tire failure or condi
-
tion.
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.
The system only warns the tire pressure is
low: it is not able to inflate them.
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 opera-
tion 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
aftermarket wheels and may contribute
to a poor overall system performance or
sensor damage. Customers are encour -
aged to use OEM wheels to assure proper
TPM 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 your 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.

Periodic Safety Checks You Should Make
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 wheel nuts 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.
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 acceler-
ator, 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.

Sealant Hose:
1. Continue to operate the pump until
sealant is no longer flowing through
hose (typically takes 30 - 70 seconds).
As the sealant flows through the Sealant
Hose, the Pressure Gauge can read as
high as 70 psi (4.8 Bar). The Pressure
Gauge will decrease quickly from
approximately 70 psi (4.8 Bar) to the
actual tire pressure when the Sealant
Bottle is empty.
2. The pump will start to inject air into the tire immediately after the Sealant Bottle
is empty. Continue to operate the pump
and inflate the tire to the cold tire infla -
tion pressure found on the tire and
loading information label located in the
driver-side door opening. Check the tire
pressure by looking at the Pressure
Gauge.
If the tire does not inflate to at least 26 psi (1.8
Bar) pressure within 15 minutes:
The tire is too badly damaged. Do not
attempt to drive the vehicle further. Call
for assistance. If the tire inflates to the recommended pressure
or is at least 26 psi (1.8 Bar) pressure within
15 minutes:
NOTE:
If the tire becomes over-inflated, push the
Deflation Button to reduce the tire pressure
to the recommended inflation pressure
before continuing.
1. Push the Power Button to turn off the

RAISING THE VEHICLE
In the case where it is necessary to raise the
vehicle, go to an authorized dealer or service
station.
TIRES
Tires — General Information
Tire Pressure
Proper tire inflation pressure is essential to
the safe and satisfactory operation of your
vehicle. Four primary areas are affected by
improper tire pressure:
Safety
Fuel Economy
Tread Wear
Ride Comfort And Vehicle StabilitySafety
Both underinflation and overinflation affect
the stability of the vehicle and can produce
a feeling of sluggish response or over respon-
siveness in the steering.
NOTE:
Unequal tire pressures from side to side
may cause erratic and unpredictable
steering response.
Unequal tire pressure from side to side
may cause the vehicle to drift left or right.
Fuel Economy
Underinflated tires will increase tire rolling
resistance resulting in higher fuel consump -
tion.
Tread Wear
Improper cold tire inflation pressures can
cause abnormal wear patterns and reduced
tread life, resulting in the need for earlier tire
replacement.
Ride Comfort And Vehicle Stability
Proper tire inflation contributes to a comfort -
able ride. Overinflation produces a jarring
and uncomfortable ride.
CAUTION!
If a transmission fluid leak occurs, visit an
authorized dealer immediately. Severe
transmission damage may occur. An
authorized dealer has the proper tools to
adjust the fluid level accurately. WARNING!
Improperly inflated tires are dangerous
and can cause collisions.
Underinflation increases tire flexing and
can result in overheating and tire failure.
Overinflation reduces a tire's ability to
cushion shock. Objects on the road and
chuckholes can cause damage that
result in tire failure.
Overinflated or underinflated tires can
affect vehicle handling and can fail
suddenly, resulting in loss of vehicle
control.
Unequal tire pressures can cause
steering problems. You could lose
control of your vehicle.
Unequal tire pressures from one side of
the vehicle to the other can cause the
vehicle to drift to the right or left.
Always drive with each tire inflated to the
recommended cold tire inflation pres-
sure.

233
Tire Inflation Pressures
The proper cold tire inflation pressure is
listed on the left side B-Pillar or rear edge of
the passenger door.Tire And Loading Information Placard
This placard tells you important information
about the:
1. Number of people that can be carried in the vehicle.
2. Tire size designed for your vehicle.
3. Cold tire inflation pressures for the front, rear, and spare tires.
At least once a month:
Check and adjust tire pressure with a good
quality pocket-type pressure gauge. Do not
make a visual judgement when deter -mining proper inflation. Tires may look
properly inflated even when they are
underinflated.
Inspect tires for signs of tire wear or visible
damage.
Inflation pressures specified on the placard
are always “cold tire inflation pressure”.
Cold tire inflation pressure 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 sitting for a
minimum of three hours. The cold tire infla -
tion pressure must not exceed the maximum
inflation pressure molded into the tire side -
wall.
Check tire pressures more often if subject to
a wide range of outdoor temperatures, as tire
pressures vary with temperature changes. Tire pressures change by approximately 1 psi
(7 kPa) per 12°F (7°C) of air temperature
change. Keep this in mind when checking
tire pressure inside a garage, especially in
the Winter.
Example: If garage temperature = 68°F
(20°C) and the outside temperature = 32°F
(0°C) then the cold tire inflation pressure
should be increased by 3 psi (21 kPa), which
equals 1 psi (7 kPa) for every 12°F (7°C) for
this outside temperature condition.
Tire pressure may increase from 2 to 6 psi
(13 to 40 kPa) during operation. DO NOT
reduce this normal pressure build up or your
tire pressure will be too low.
Tire Pressures For High Speed Operation
The manufacturer advocates driving at safe
speeds and within posted speed limits.
Where speed limits or conditions are such
that the vehicle can be driven at high speeds,
maintaining correct tire inflation pressure is
very important. Increased tire pressure and
reduced vehicle loading may be required for
high speed vehicle operation. Refer to an
authorized tire dealer or original equipment
vehicle dealer for recommended safe oper
-
ating speeds, loading and cold tire inflation
pressures.
CAUTION!
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 valve stem.

SERVICING AND MAINTENANCE
234
Loading
The vehicle maximum load on the tire must
not exceed the load carrying capacity of the
tire on your vehicle. You will not exceed the
tire's load carrying capacity if you adhere to
the loading conditions, tire size, and cold tire
inflation pressures specified on the Tire
Information placard.
NOTE:
Under a maximum loaded vehicle condition,
gross axle weight ratings (GAWRs) for the
front and rear axles must not be exceeded.
Radial Ply Tires
Tire Repair
If your tire becomes damaged, it may be
repaired if it meets the following criteria:
The tire has not been driven on when flat.
The damage is only on the tread section of
your tire (sidewall damage is not repair-
able).
The puncture is no greater than a ¼ of an
inch (6 mm). Consult an authorized tire dealer for tire
repairs and additional information.
Damaged Run Flat tires, or Run Flat tires
that have experienced a loss of pressure
should be replaced immediately with another
Run Flat tire of identical size and service
description (Load Index and Speed Symbol).
Replace the tire pressure sensor as well as it
is not designed to be reused.
Run Flat Tires — If Equipped

Run Flat tires allow you the capability to drive
50 miles (80 km) at 50 mph (80 km/h) after
a rapid loss of inflation pressure. This rapid
loss of inflation is referred to as the Run Flat
mode. A Run Flat mode occurs when the tire
inflation pressure is of/or below 14 psi (96
kPa). Once a Run Flat tire reaches the run flat
mode it has limited driving capabilities and
needs to be replaced immediately. A Run Flat
tire is not repairable. When a run flat tire is
changed after driving with underinflated tire
condition, please replace the TPM sensor as it
is not designed to be reused when driven
under run flat mode (14 psi (96 kPa)) condi -
tion.

NOTE:
TPM Sensor must be replaced after driving
the vehicle on a flat tire condition.
WARNING!
High speed driving with your vehicle under
maximum load is dangerous. The added
strain on your tires could cause them to
fail. You could have a serious collision. Do
not drive a vehicle loaded to the maximum
capacity at continuous speeds above
75 mph (120 km/h).
WARNING!
Overloading of your tires is dangerous.
Overloading can cause tire failure, affect
vehicle handling, and increase your
stopping distance. Use tires of the
recommended load capacity for your
vehicle. Never overload them.
WARNING!
Combining radial ply tires with other types
of tires on your vehicle will cause your
vehicle to handle poorly. The instability
could cause a collision. Always use radial
ply tires in sets of four. Never combine
them with other types of tires.
