The gear selection must match vehicle
uphill direction (i.e., vehicle facing uphill
is in forward gear; vehicle backing uphill is
in REVERSE gear).
HSA will work in REVERSE gear and all
forward gears. The system will not activate
if the transmission is in PARK or
NEUTRAL. For vehicles equipped with a
manual transmission, if the clutch is
pressed, HSA will remain active.
Towing With HSA
HSA will also provide assistance to mitigate
roll back while towing a trailer.
Disabling And Enabling HSA
This feature can be turned on or turned off.
To change the current setting, proceed as
follows:
If disabling HSA using Uconnect Settings,
refer to “Uconnect Settings” in “Multi-
media” for further information.
Rain Brake Support (RBS)
Rain Brake Support (RBS) may improve
braking performance in wet conditions. It
will periodically apply a small amount of
brake pressure to remove any water buildup
on the front brake rotors. It functions when
the windshield wipers are in LO or HI speed.
When Rain Brake Support is active, there is
no notification to the driver and no driver
interaction is required.
Ready Alert Braking (RAB)
Ready Alert Braking (RAB) may reduce the
time required to reach full braking during
emergency braking situations. It anticipates
when an emergency braking situation may
occur by monitoring how fast the throttle is
released by the driver. The EBC will prepare
the brake system for a panic stop.
WARNING!
There may be situations where the Hill
Start Assist (HSA) will not activate and
slight rolling may occur, such as on minor
hills or with a loaded vehicle, or while
pulling a trailer. HSA is not a substitute for
active driving involvement. It is always the
driver’s responsibility to be attentive to
distance to other vehicles, people, and
objects, and most importantly brake
operation to ensure safe operation of the
vehicle under all road conditions. Your
complete attention is always required
while driving to maintain safe control of
your vehicle. Failure to follow these
warnings can result in a collision or serious
personal injury.
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
rolling down an incline while resuming
acceleration, manually activate the
trailer brake or apply more vehicle brake
pressure 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
result in a collision or serious personal
injury.

Traction Control System (TCS)
The Traction Control System (TCS) 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 spin-
ning wheel(s) and/or reduce vehicle power to
provide enhanced acceleration and stability.
A feature of the TCS, Brake Limited Differen -
tial (BLD), functions similar to a limited slip
differential and controls 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 vehicle torque to
be applied to the wheel that is not spinning.
BLD may remain enabled even if TCS and
ESC are in a reduced mode.
Trailer Sway Control (TSC)
Trailer Sway Control (TSC) uses sensors in
the vehicle to recognize an excessively
swaying trailer and will take the appropriate
actions to attempt to stop the sway. TSC will
become active automatically once an exces -
sively swaying trailer is recognized.
NOTE:
TSC cannot stop all trailers from swaying.
Always use caution when towing a trailer and
follow the trailer tongue weight recommen -dations. Refer to “Trailer Towing” in
“Starting And Operating” for further informa
-
tion.
When TSC is functioning, the “ESC Activa -
tion/Malfunction Indicator Light” will flash,
the engine power may be reduced and you
may feel the brakes being applied to indi -
vidual wheels to attempt to stop the trailer
from swaying. TSC is disabled when the ESC
system is in the “Partial Off” or “Full Off”
modes.
AUXILIARY DRIVING
SYSTEMS
Blind Spot Monitoring (BSM) — If
Equipped
The Blind Spot Monitoring (BSM) system
uses two radar-based sensors, located inside
the rear bumper fascia, 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 rear view mirrors to let the
driver know that the system is operational.
The BSM system sensors operate when the
vehicle is in any forward gear or REVERSE
and enters standby mode when the vehicle is
in PARK.
The BSM detection zone covers approxi -
mately one lane width on both sides of the
vehicle 12 ft (3.8 m). The zone length starts
at the outside mirror and extends approxi -
mately 10 ft (3 m) beyond the rear bumper
of the vehicle. The BSM system monitors the
detection zones on both sides of the vehicle
when the vehicle speed reaches approxi -
mately 6 mph (10 km/h) or higher and will
alert the driver of vehicles in these areas.
WARNING!
If TSC activates while driving, slow the
vehicle down, stop at the nearest safe
location, and adjust the trailer load to
eliminate trailer sway.
2020_JEEP_M6_UG_UK.book Page 80

81
NOTE:
The BSM system does NOT alert the driver
about rapidly approaching vehicles that
are outside the detection zones.
The BSM system detection zone DOES
NOT change if your vehicle is towing a
trailer. Therefore, visually verify the adja-
cent 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 the BSM
warning light remaining illuminated the
entire time the vehicle is in a forward gear.
It may be necessary to deactivate the BSM
system manually to avoid miss-detection.
Refer to “Uconnect Settings” in “Multi-
media” in the Owner’s Manual for further
information.
The Blind Spot Monitoring (BSM) system
may experience drop outs (blinking on and
off) of the side mirror Warning Indicator
lamps when a motorcycle or any small
object remains at the side of the vehicle
for extended periods of time (more than a
couple of seconds).
The area on the rear fascia where the radar
sensors are located must remain free of
snow, ice, and dirt/road contamination so that the BSM system can function properly.
Do not block the area of the rear fascia where
the radar sensors are located with foreign
objects (bumper stickers, bicycle racks, etc.)
Radar Sensor Location (Passenger Side Shown)
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. When -
ever a turn signal and detected object are
present on the same side at the same time,
both the visual and audio alerts will be
issued. In addition to the audible alert the
radio (if on) will also be muted. Warning Light Location
The BSM system monitors the detection
zone from three different entry points (side,
rear, front) while driving to see if an alert is
necessary. The BSM system will issue an
alert during these types of zone entries.

Overtaking Traffic
If you pass another vehicle slowly with a rela -
tive speed less than 10 mph (16 km/h) and
the vehicle remains in the blind spot for
approximately 1.5 seconds, the warning light
will be illuminated. If the difference in speed
between the two vehicles is greater than
10 mph (16 km/h), the warning light will not
illuminate. Overtaking/Approaching
Overtaking/Passing
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. Stationary Objects
The BSM system will not alert you of objects
that are traveling in the opposite direction of
the vehicle in adjacent lanes.
NOTE:
The BSM system may experience drop outs
(blinking on and off) in the side mirror LED
icons while a motorcycle, or any small target,
remains at the vehicle’s B-pillar for an
extended period of time (longer than a
couple of seconds).

Rear Cross Path (RCP)
The Rear Cross Path (RCP) feature 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 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 3 mph(5 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 and the vehicle is in
REVERSE, the driver is alerted using both
the visual and audible alarms, including
reducing the radio volume.
Modes Of Operation
Three selectable modes of operation are
available in the Uconnect System. Refer to
“Uconnect Settings” in “Multimedia” in the
Owner’s Manual for further information.
Blind Spot Alert Lights Only (Default Setting)
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
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 Detection (RCP) is not a
back up aid system. It is intended to be
used to help a driver detect an oncoming
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.

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
volume is reduced. 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 oper-
ating mode when the vehicle is shut off.
Each time the vehicle is started the previ -
ously stored mode will be recalled and used.
Blocked Sensor
If the system detects degraded performance
due to contamination or foreign objects, a
message will warn you of a blocked sensor and the warning indicators in side view
mirrors will be illuminated. The warning indi
-
cators will remain illuminated until blockage
clearing conditions are met. First clear the
fascia area around the sensors of the
blockage. After removing the blockage, reset
the system by placing the ignition from ON to
OFF and then back ON.
Forward Collision Warning (FCW) With
Mitigation — If Equipped
Forward Collision Warning (FCW) With
Mitigation Operation
The Forward Collision Warning (FCW) system
with mitigation provides the driver with
audible warnings, visual warnings (within the
instrument cluster display), and may apply a
brake jerk 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:
FCW monitors the information from the
forward looking sensors as well as the Elec -
tronic Brake Controller (EBC), to calculate
the probability of a forward collision. When
the system determines that a forward colli -sion 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.
If a Forward Collision Warning with Mitiga
-
tion event begins at a speed below 26 mph
(42 km/h), the system may provide the
maximum braking possible to mitigate the
potential forward collision. If the Forward
Collision Warning with Mitigation event stops
the vehicle completely, the system will hold
the vehicle at standstill for two seconds and
then release the brakes.
2020_JEEP_M6_UG_UK.book Page 84

85
FCW Message
When the system determines a collision with
the vehicle in front of you is no longer prob -
able, the warning message will be deacti -
vated.
NOTE:
The minimum speed for FCW activation is
1 mph (2 km/h).

The FCW alerts may be triggered on objects
other than vehicles, such as guard rails or
sign posts, based on the course prediction.
This is expected and is a part of normal
FCW activation and functionality.
It is unsafe to test the FCW system. To
prevent such misuse of the system, after
four Active Braking events within a key
cycle, the Active Braking portion of FCW
will be deactivated until the next key cycle.

The FCW system is intended for on-road
use only. If the vehicle is taken off-road,
the FCW system should be deactivated to
prevent unnecessary warnings to the
surroundings.
FCW Settings
The forward collision menu setting is located
in the Uconnect settings.
NOTE:
The default status of FCW is “Full On,” this
allows the system to provide a warning and
autonomous braking in the event of a poten -
tial frontal collision.
Changing the FCW status to “Warning Only”
prevents the system from providing autono -
mous braking, or additional brake support if
the driver is not braking adequately in the
event of a potential frontal collision. Changing the FCW status to off deactivates
the system, so no warning or autonomous
braking will be available in case of a possible
collision
NOTE:
The FCW system state is defaulted to "Full
On" from one ignition cycle to the next. If the
system is turned off, it will reset to "Full On"
when the vehicle is restarted.
Changing FCW Sensitivity And Operating
Status
The FCW Sensitivity And Operation Settings
are programmable through the Uconnect
System. Refer to “Uconnect Settings” in
“Multimedia” for further information.
The default status of FCW is the “Medium”
setting and the FCW is in the “Full On”
setting. This allows the system to warn the
driver of a possible collision with the vehicle
in front using audible/visual warnings and it
applies autonomous braking.
Changing the FCW status to the “Far” setting
allows the system to warn the driver of a
possible collision with the vehicle in front
using audible/visual warning when the latter
is at a farther distance than "Medium"
setting. This provides the most reaction time
to avoid a possible collision.
WARNING!

Forward Collision Warning (FCW) is not
intended to avoid a collision on its own, nor
can FCW detect every type of potential
collision. 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.

2020_JEEP_M6_UG_UK.book Page 85

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.
2020_JEEP_M6_UG_UK.book Page 87

Premium System
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.
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 will display in the instru -
ment cluster display.
Tire Pressure Monitoring System Warning

Tire Pressure Monitoring Low Pressure
Warnings
The Tire Pressure Monitoring
System Warning Light will illumi -nate 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 addi
-
tion, the instrument cluster will display a
"Tire Low" message and a graphic showing
the pressure values of each tire with the low
tire pressure values highlighted or in a
different color.
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 highlighted or in a different color
in the instrument cluster display graphic) to
the vehicle’s recommended cold placard
pressure value. Once the system receives the
updated tire pressures, the system will auto -
matically update, the pressure values in the
graphic display in the instrument cluster will stop being highlighted or return to their orig
-
inal color, and the Tire Pressure Monitoring
System 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 Tire
Pressure Monitoring System 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 informa -
tion.
Service TPMS Warning
When a system fault is detected, the Tire
Pressure Monitoring System Warning 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" message 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
