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.

(Continued)ESC Operating Modes
NOTE:
Depending upon model and mode of opera-
tion, the ESC system may have multiple
operating modes. ESC OFF Button
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.
WARNING!
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 acci -
dents, including those resulting from
excessive speed in turns, driving on very
slippery surfaces, or hydroplaning. ESC
also cannot prevent accidents resulting
from loss of vehicle control due to inap -
propriate driver input for the conditions.
Only a safe, attentive, and skillful driver
can prevent accidents. The capabilities
of an ESC equipped vehicle must never
be exploited in a reckless or dangerous
manner which could jeopardize the
user’s safety or the safety of others.Vehicle modifications, or failure to prop -
erly maintain your vehicle, may change
the handling characteristics of your
vehicle, and may negatively affect the
performance of the ESC system.
Changes to the steering system, suspen -
sion, braking system, tire type and size
or wheel size may adversely affect ESC
performance. Improperly inflated and
unevenly worn tires may also degrade
ESC performance. Any vehicle modifica-
tion or poor vehicle maintenance that
reduces the effectiveness of the ESC
system can increase the risk of loss of
vehicle control, vehicle rollover, personal
injury and death.
WARNING! (Continued)

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.

exists. If the system fault no longer exists,
the Tire Pressure Monitoring System Warning
Light will no longer flash, and the “SERVICE
TPM SYSTEM” message will no longer
display, and a pressure 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.
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 or non-matching full size 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 Tire Pressure
Monitoring System Warning Light will
remain on and a chime will sound. In
addition, the graphic in the instrument
cluster will still display a different color
or highlighted pressure value.
3. After driving the vehicle for up to 10 minutes above 15 mph (24 km/h),
the Tire Pressure Monitoring System
Warning Light will flash on and off for
75 seconds and then remain on solid. In
addition, the instrument cluster will
display a “SERVICE TPM SYSTEM”
message for five seconds and then
display dashes (- -) in place of the pres -
sure value.
4. For each subsequent ignition key cycle, a chime will sound, the Tire Pressure
Monitoring System Warning Light will
flash on and off for 75 seconds and then
remain on solid, and the instrument
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, the TPMS
will update automatically. In addition,
the Tire Pressure Monitoring System
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 infor -
mation.
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 Tire Pressure

SAFETY
98
Seat Belt Pretensioner
The front and second row outboard seat belt
systems are equipped with pretensioning
devices that are designed to remove slack
from the seat belt in the event of a collision.
These devices may improve the performance
of the seat belt by removing slack from the
seat belt early in a collision. Pretensioners
work for all size occupants, including those
in child restraints.
NOTE:
These devices are not a substitute for proper
seat belt placement by the occupant. The
seat belt still must be worn snugly and posi-
tioned properly.
The pretensioners are triggered by the Occu -
pant Restraint Controller (ORC). Like the air
bags, the pretensioners are single use items.
A deployed pretensioner or a deployed air
bag must be replaced immediately.
Energy Management Feature — If Equipped
The front outboard seat belt system is
equipped and the second row outboard seat
belt system may be equipped with an Energy
Management feature that may help further
reduce the risk of injury in the event of a collision. The seat belt system has a retractor
assembly that is designed to release webbing
in a controlled manner.
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
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 igni -
tion switch is in the START or ON/RUN posi -
tion. 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
2020_JEEP_M6_UG_UK.book Page 98

Front Air Bag Operation
Front Air Bags are designed to provide addi-
tional protection by supplementing the seat
belts. Front air bags are not expected to
reduce the risk of injury in rear, side, or roll -
over collisions. The front air bags will not
deploy in all frontal collisions, including
some that may produce substantial vehicle
damage — for example, some pole colli -
sions, truck underrides, and angle offset
collisions.
On the other hand, depending on the type
and location of impact, front air bags may
deploy in crashes with little vehicle front-end
damage but that produce a severe initial
deceleration.
Because air bag sensors measure vehicle
deceleration over time, vehicle speed and
damage by themselves are not good indica -
tors of whether or not an air bag should have
deployed.
Seat belts are necessary for your protection
in all collisions, and also are needed to help
keep you in position, away from an inflating
air bag.
When the ORC detects a collision requiring
the front air bags, it signals the inflator units. A large quantity of non-toxic gas is generated
to inflate the front air bags.
The steering wheel hub trim cover and the
upper passenger side of the instrument
panel separate and fold out of the way as the
air bags inflate to their full size. The front air
bags fully inflate in less time than it takes to
blink your eyes. The front air bags then
quickly deflate while helping to restrain the
driver and front passenger.
Passenger Air Bag Disable Feature — If
Equipped
This system allows the driver to DISABLE
(OFF) the Passenger Advanced Front Air Bag
if a child restraint
must be installed in the
front seat. Only DISABLE (OFF) the
Passenger Advanced Front Air Bag if it is
absolutely necessary to install a child
restraint in the front seat. Children 12 years
or younger should ride properly buckled up in
a rear seat, if available. According to crash
statistics, children are safer when properly
restrained in the rear seats rather than in the
front. (Refer to “Child Restraints” in this
section for further information.)
WARNING!
A DISABLED (OFF) Passenger Advanced
Front Air Bag is deactivated and will not
deploy in a collision.
A DISABLED (OFF) Passenger Advanced
Front Air Bag will not provide a front
passenger additional protection by
supplementing the seat belts.
Do not install a child restraint in the
front seat unless the Passenger Air Bag
DISABLE (OFF) Indicator light on the
center stack is illuminated to show that
the Passenger Advanced Front Air Bag is
DISABLED (OFF).
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.

STARTING AND OPERATING
146
FOUR-WHEEL DRIVE
OPERATION — IF EQUIPPED
Jeep Active Drive
Your vehicle may be equipped with a Power
Transfer Unit (PTU). This system is auto-
matic with no driver inputs or additional
driving skills required. Under normal driving
conditions, the front wheels provide most of
the traction. If the front wheels begin to lose
traction, power is shifted automatically to
the rear wheels. The greater the front wheel
traction loss, the greater the power transfer
to the rear wheels.
Additionally, on dry pavement under heavy
throttle input (where one may have no wheel
spin), torque will be sent to the rear in a
preemptive effort to improve vehicle launch
and performance characteristics.
Four Wheel Drive (4x4)
The four wheel drive (4WD) is fully automatic
in normal driving mode.
NOTE:
It is not possible to carry out the change of
mode when the vehicle exceeds the speed of
75 mph (120 km/h).
Enabling Four Wheel Drive (4x4)
The buttons for the activation of four wheel
drive are located on the device Selec-Terrain
and allow you to select the following:
4WD LOCK
4WD LOW — (Trailhawk models only)
Active Drive Control — If Equipped
Selec-Terrain Switch The Power Transfer Unit (PTU) is locked to
ensure immediate availability of torque to
the rear drive axles. This feature is selectable
in AUTO mode and automatic in the other
driving mode. 4WD LOCK can be enabled by
the following ways:
When the 4WD LOCK button is pushed.
When the Selec-Terrain switch is rotated
from AUTO to any other off-road modes.
Active Drive With Low Control — (Trailhawk
models only)
Selec-Terrain Switch (Trailhawk)
CAUTION!
All wheels must have the same size and
type tires. Unequal tire sizes must not be
used. Unequal tire size may cause failure
of the power transfer unit.
2020_JEEP_M6_UG_UK.book Page 146

161
During the maneuver, the system asks to
shift to REVERSE, select the direction indi-
cator in the direction you want to exit. Let go
of the steering wheel and press the dedi -
cated pedals, while the system handles the
steering automatically for exiting the parking
space. If the driver continues to carry out a
voluntary or involuntary action on the
steering wheel during the exit maneuver
(touching or holding the steering wheel to
prevent its movement), the maneuver will be
interrupted.
End Of Maneuver
The semi-automatic maneuver ends when
the display shows the message of a
completed maneuver. At the end of the
maneuver, the system gives back the vehicle
control to the driver.
Important Information
If the sensors undergo impact which alters
their position, the system operation could
be greatly affected.
The sensors reach top performance after
the vehicle has gone about 30 miles
(50 km) due to the dynamic tire circum -
ference calculations used for parking.
Clean the ParkSense sensors regularly,
taking care not to scratch or damage them.
The sensors must not be covered with ice,
snow, slush, mud, dirt or debris. Failure to
do so can result in the system not working
properly. The ParkSense system might not
detect an obstacle behind or in front of the
fascia/bumper, or it could provide a false
indication that an obstacle is behind or in
front of the fascia/bumper.
Construction equipment, large trucks, and
other vibrations could affect the perfor -
mance of ParkSense.
Sensors may detect a nonexistent obstacle
(echo noise) due to mechanical noises, for
example while washing the vehicle or in
the case of rain, strong wind, and hail.
The sensors may not detect objects of a
particular shape or made from particular
materials (very thin poles, trailer beams,
panels, nets, bushes, anti-parking posts,
pavements, rubbish bins, motor vehicles,
etc.). Always take great care to check that
the vehicle and its path are actually
compatible with the parking place identi -
fied by the system.
The use of wheels and tires that are
different size to the original equipment
could affect the operation of the system.
The operation of the rear sensors is auto-
matically deactivated when the trailer's
electric plug is inserted in the vehicle's
tow hook socket, while the front sensors
stay active and can provide acoustic and
visual warnings. The rear sensors are auto-
matically reactivated when the trailer's
cable plug is removed.
In "Search in progress" mode, the system
could incorrectly identify a parking place
to carry out the maneuver (e.g. by a junc-
tion, driveways, roads crossing the direc-
tion of travel, etc.).
In the case of parking maneuvers on roads
on a slope, the performance of the system
could be inferior and it may deactivate.
If a parking maneuver is being carried out
between two parked vehicles alongside the
pavement, the system may cause the
vehicle to mount the pavement.
Some maneuvers at very tight bends might
be impossible to be carried out.
2020_JEEP_M6_UG_UK.book Page 161

STARTING AND OPERATING
172
Tongue Weight (TW)
The tongue weight is the downward force
exerted on the hitch ball by the trailer. You
must consider this as part of the load on your
vehicle.
Trailer Frontal Area
The frontal area is the maximum height
multiplied by the maximum width of the
front of a trailer.
Trailer Sway Control
The trailer sway control can be a mechanical
telescoping link that can be installed
between the hitch receiver and the trailer
tongue that typically provides adjustable fric-
tion associated with the telescoping motion
to dampen any unwanted trailer swaying
motions while traveling.
If equipped, the electronic Trailer Sway
Control (TSC) recognizes a swaying trailer
and automatically applies individual wheel
brakes and/or reduces engine power to
attempt to eliminate the trailer sway.
Weight-Carrying Hitch
A weight-carrying hitch supports the trailer
tongue weight, just as if it were luggage
located at a hitch ball or some other
connecting point of the vehicle. These kinds
of hitches are the most popular on the
market today and they are commonly used to
tow small and medium sized trailers.
Weight-Distributing Hitch
A weight-distributing system works by
applying leverage through spring (load) bars.
They are typically used for heavier loads to
distribute trailer tongue weight to the tow
vehicle's front axle and the trailer axle(s).
When used in accordance with the manufac -
turer's directions, it provides for a more level
ride, offering more consistent steering and
brake control thereby enhancing towing
safety. The addition of a friction/hydraulic
sway control also dampens sway caused by
traffic and crosswinds and contributes posi -
tively to tow vehicle and trailer stability. Trailer sway control and a weight distributing
(load equalizing) hitch are recommended for
heavier Tongue Weights (TW) and may be
required depending on vehicle and trailer
configuration/loading to comply with Gross
Axle Weight Rating (GAWR) requirements.
WARNING!
An improperly adjusted Weight Distrib
-
uting Hitch system may reduce
handling, stability, braking performance,
and could result in a collision.
Weight Distributing Systems may not be
compatible with Surge Brake Couplers.
Consult with your hitch and trailer manu -
facturer or a reputable Recreational
Vehicle dealer for additional informa-
tion.

SERVICING AND MAINTENANCE
236
(Continued)
NOTE:
Wheel Valve Stem must be replaced as well
when installing new tires due to wear and
tear in existing tires.
Keep dismounted tires in a cool, dry place
with as little exposure to light as possible.
Protect tires from contact with oil, grease,
and gasoline.
Replacement Tires
The tires on your new vehicle provide a
balance of many characteristics. They should
be inspected regularly for wear and correct
cold tire inflation pressures. The manufac-
turer strongly recommends that you use tires
equivalent to the originals in size, quality
and performance when replacement is
needed. Refer to the paragraph on “Tread
Wear Indicators” in this section. Refer to the
Tire and Loading Information placard or the
Vehicle Certification Label for the size desig -
nation of your tire. The Load Index and
Speed Symbol for your tire will be found on
the original equipment tire sidewall.
It is recommended to replace the two front
tires or two rear tires as a pair. Replacing just
one tire can seriously affect your vehicle’s
handling. If you ever replace a wheel, make
sure that the wheel’s specifications match
those of the original wheels. It is recommended you contact an authorized
tire dealer or original equipment dealer with
any questions you may have on tire specifica
-
tions or capability. Failure to use equivalent
replacement tires may adversely affect the
safety, handling, and ride of your vehicle.
Tire Types
All Season Tires — If Equipped
All Season tires provide traction for all
seasons (Spring, Summer, Fall, and Winter).
Traction levels may vary between different all
season tires. All season tires can be identi -
fied by the M+S, M&S, M/S or MS designa -
tion on the tire sidewall. Use all season tires
only in sets of four; failure to do so may
adversely affect the safety and handling of
your vehicle.
WARNING!
Do not use a tire, wheel size, load rating,
or speed rating other than that specified
for your vehicle. Some combinations of
unapproved tires and wheels may change
suspension dimensions and performance
characteristics, resulting in changes to
steering, handling, and braking of your
vehicle. This can cause unpredictable
handling and stress to steering and
suspension components. You could lose
control and have a collision resulting in
serious injury or death. Use only the tire
and wheel sizes with load ratings
approved for your vehicle.
Never use a tire with a smaller load index
or capacity, other than what was origi -
nally equipped on your vehicle. Using a
tire with a smaller load index could result
in tire overloading and failure. You could
lose control and have a collision.
Failure to equip your vehicle with tires
having adequate speed capability can
result in sudden tire failure and loss of
vehicle control.
CAUTION!
Replacing original tires with tires of a
different size may result in false
speedometer and odometer readings.
