SAFETY FEATURES
Anti-Lock Brake System (ABS)
The Anti-Lock Brake System (ABS) provides
increased vehicle stability and brake perfor-
mance under most braking conditions. The
system automatically prevents wheel lock,
and enhances vehicle control during braking.
The ABS performs a self-check cycle to
ensure that the ABS is working properly each
time the vehicle is started and driven. During
this self-check, you may hear a slight
clicking sound as well as some related motor
noises.
ABS is activated during braking when the
system detects one or more wheels begin to
lock. Road conditions such as ice, snow,
gravel, bumps, railroad tracks, loose debris,
or panic stops may increase the likelihood of
ABS activation(s).
You also may experience the following when
ABS activates:
The ABS motor noise (it may continue to
run for a short time after the stop)
The clicking sound of solenoid valves
Brake pedal pulsations
A slight drop of the brake pedal at the end
of the stop
These are all normal characteristics of ABS.
ABS is designed to function with the Original
Equipment Manufacturer’s tires. Modifica-
tion may result in degraded ABS perfor -
mance.
Anti-Lock Brake Warning Light
The yellow “Anti-Lock Brake Warning Light”
will turn on when the ignition is turned to the
ON/RUN mode and may stay on for as long
as four seconds.
If the “Anti-Lock Brake Warning Light”
remains on or comes on while driving, it indi -
cates that the anti-lock portion of the brake
system is not functioning and that service is
required. However, the conventional brake
system will continue to operate normally if
the “Anti-Lock Brake Warning Light” is on.
WARNING!
The ABS contains sophisticated elec-
tronic equipment that may be suscep -
tible to interference caused by
improperly installed or high output radio
transmitting equipment. This interfer -
ence can cause possible loss of anti-lock
braking capability. Installation of such
equipment should be performed by qual -
ified professionals.
Pumping of the Anti-Lock Brakes will
diminish their effectiveness and may
lead to a collision. Pumping makes the
stopping distance longer. Just press
firmly on your brake pedal when you
need to slow down or stop.
The ABS cannot prevent the natural laws
of physics from acting on the vehicle, nor
can it increase braking or steering effi -
ciency beyond that afforded by the
condition of the vehicle brakes and tires
or the traction afforded.
The ABS cannot prevent collisions,
including those resulting from excessive
speed in turns, following another vehicle
too closely, or hydroplaning.
The capabilities of an ABS equipped
vehicle must never be exploited in a
reckless or dangerous manner that could
jeopardize the user’s safety or the safety
of others.

If the “Anti-Lock Brake Warning Light” is on,
the brake system should be serviced as soon
as possible to restore the benefits of
anti-lock brakes. If the “Anti-Lock Brake
Warning Light” does not come on when the
ignition is turned to the ON/RUN mode, have
the light repaired as soon as possible.
Electronic Brake Control System
Your vehicle is equipped with an advanced
Electronic Brake Control system (EBC). This
system includes Electronic Brake Force
Distribution (EBD), Anti-Lock Brake System
(ABS), Brake Assist System (BAS), Hill Start
Assist (HSA), Traction Control System (TCS),
Electronic Stability Control (ESC), and Elec-
tronic Roll Mitigation (ERM). These systems
work together to enhance both vehicle
stability and control in various driving condi -
tions.
Your vehicle may also be equipped with
Ready Alert Braking (RAB), Rain Brake
Support (RBS), Trailer Sway Control (TSC),
Hill Descent Control (HDC), and Dynamic
Steering Torque (DST).
Brake Assist System (BAS) — If Equipped
The Brake Assist System (BAS) is designed
to optimize the vehicle’s braking capability during emergency braking maneuvers. The
system detects an emergency braking situa
-
tion by sensing the rate and amount of brake
application and then applies optimum pres -
sure to the brakes. This can help reduce
braking distances. The BAS complements
the Anti-Lock Brake System (ABS). Applying
the brakes very quickly results in the best
BAS assistance. To receive the benefit of the
system, you must apply continuous braking
pressure during the stopping sequence, (do
not “pump” the brakes). Do not reduce brake
pedal pressure unless braking is no longer
desired. Once the brake pedal is released,
the BAS is deactivated.
Brake System Warning Light
The red “Brake System Warning Light” will
turn on when the ignition is turned to the ON/
RUN mode and may stay on for as long as
four seconds.
If the “Brake System Warning Light”
remains on or comes on while driving, it indi -
cates that the brake system is not func -
tioning properly and that immediate service
is required. If the “Brake System Warning
Light” does not come on when the ignition is
turned to the ON/RUN mode, have the light
repaired as soon as possible.
Dynamic Steering Torque (DST)
Dynamic Steering Torque (DST) is a feature
of the ESC and Electric Power Steering
(EPS) modules that provides torque at the
steering wheel for certain driving conditions
in which the ESC module is detecting vehicle
instability. The torque that the steering
wheel receives is only meant to help the
driver realize optimal steering behavior in
order to reach/maintain vehicle stability. The
only notification the driver receives that the
feature is active is the torque applied to the
steering wheel. WARNING!
The Brake Assist System (BAS) cannot
prevent the natural laws of physics from
acting on the vehicle, nor can it increase
the traction afforded by prevailing road
conditions. BAS cannot prevent collisions,
including those resulting from excessive
speed in turns, driving on very slippery
surfaces, or hydroplaning. The capabilities
of a BAS-equipped vehicle must never be
exploited in a reckless or dangerous
manner, which could jeopardize the user's
safety or the safety of others.
2020_JEEP_M6_UG_UK.book Page 73

SAFETY
74
NOTE:
The DST feature is only meant to help the
driver realize the correct course of action
through small torques on the steering wheel,
which means the effectiveness of the DST
feature is highly dependent on the driver’s
sensitivity and overall reaction to the applied
torque. It is very important to realize that this
feature will not steer the vehicle, meaning
the driver is still responsible for steering the
vehicle.
Electronic Brake Force Distribution (EBD)
This function manages the distribution of the
braking torque between the front and rear
axles by limiting braking pressure to the rear
axle. This is done to prevent overslip of the
rear wheels to avoid vehicle instability, and
to prevent the rear axle from entering ABS
before the front axle.
Electronic Roll Mitigation (ERM)
Electronic Roll Mitigation (ERM) anticipates
the potential for wheel lift by monitoring the
driver’s steering wheel input and the speed
of the vehicle. When ERM determines that
the rate of change of the steering wheel
angle and vehicle’s speed are sufficient to
potentially cause wheel lift, it then appliesthe appropriate brake and may also reduce
engine power to lessen the chance that
wheel lift will occur. ERM can only reduce
the chance of wheel lift occurring during
severe or evasive driving maneuvers; it
cannot prevent wheel lift due to other
factors, such as road conditions, leaving the
roadway, or striking objects or other vehicles.Electronic Stability Control (ESC)
Electronic Stability Control (ESC) enhances
directional control and stability of the
vehicle under various driving conditions.
ESC corrects for oversteering or under
-
steering of the vehicle by applying the brake
of the appropriate wheel(s) to assist in coun -teracting the oversteer or understeer condi
-
tion. Engine power may also be reduced to
help the vehicle maintain the desired path.
ESC uses sensors in the vehicle to determine
the vehicle path intended by the driver and
compares it to the actual path of the vehicle.
When the actual path does not match the
intended path, ESC applies the brake of the
appropriate wheel to assist in counteracting
the oversteer or understeer condition.
Oversteer — when the vehicle is turning
more than appropriate for the steering
wheel position.
Understeer — when the vehicle is turning
less than appropriate for the steering
wheel position.
The “ESC Activation/Malfunction Indicator
Light” located in the instrument cluster will
start to flash as soon as the ESC system
becomes active. The “ESC Activation/
Malfunction Indicator Light” also flashes
when the TCS is active. If the “ESC Activa -
tion/Malfunction Indicator Light” begins to
flash during acceleration, ease up on the
accelerator and apply as little throttle as
possible. Be sure to adapt your speed and
driving to the prevailing road conditions.
WARNING!
Many factors, such as vehicle loading,
road conditions and driving conditions,
influence the chance that wheel lift or
rollover may occur. ERM cannot prevent all
wheel lift or roll overs, especially those
that involve leaving the roadway or striking
objects or other vehicles. The capabilities
of an ERM-equipped vehicle must never
be exploited in a reckless or dangerous
manner which could jeopardize the user's
safety or the safety of others.

76(Continued)
To enter the “Partial Off” mode, momentarily
push the “ESC OFF” switch and the “ESC
Off Indicator Light” will illuminate. To turn
the ESC on again, momentarily push the
“ESC OFF” switch and the “ESC Off Indi-
cator Light” will turn off.
NOTE:
When driving with snow chains, or when
starting off in deep snow, sand, or gravel, it
may be desirable to allow more wheel spin.
This can be accomplished by momentarily
pushing the “ESC Off” button to enter partial
mode “Partial Off” mode. Once the situation
requiring “Partial Off” mode is overcome,
turn ESC back on by momentarily pushing
the “ESC OFF” button. This may be done
while the vehicle is in motion. Full Off (Four-Wheel Drive Models Only)
This mode is intended for off-highway or
off-road use when ESC stability features
could inhibit vehicle maneuverability due to
trail conditions. This mode is entered by
pushing and holding the “ESC OFF” switch
for five seconds when the vehicle is stopped
and the engine is running. After five
seconds, the "ESC Off Indicator Light" will
illuminate and the “ESC Off” message will
appear in the instrument cluster display.
In this mode, ESC and TCS, except for the
“limited slip” feature described in the TCS
section, are turned off until the vehicle
reaches a speed of 40 mph (64 km/h). At
40 mph (64 km/h), the system returns to
“Partial Off” mode, as described above. TCS
remains off. When the vehicle speed drops
below 30 mph (48 km/h), the ESC system
shuts off. ESC is deactivated at low vehicle
speeds so that it will not interfere with
off-road driving. However, ESC function returns to provide the stability feature at
speeds above 40 mph (64 km/h). The "ESC
Off Indicator Light" will always be illumi
-
nated when ESC is off.
To turn ESC on again, momentarily push the
“ESC Off” switch. This will restore the “ESC
On” mode of operation.
NOTE:
The “ESC Off” message will display and an
audible chime will sound when the gear
selector is placed into the PARK position
from any other position, and then moved out
of the PARK position. This will occur even if
the message was previously cleared.
WARNING!
When in “Partial Off” mode, the TCS
functionality of ESC, (except for the
limited slip feature described in the TCS
section), has been disabled and the
“ESC Off Indicator Light” will be illumi -
nated. When in “Partial Off” mode, the
engine power reduction feature of TCS is
disabled, and the enhanced vehicle
stability offered by the ESC system is
reduced.
Trailer Sway control (TSC) is disabled
when the ESC system is in the “Partial
Off” mode.
WARNING! (Continued)
WARNING!
In the "Full Off" mode, the engine torque
reduction and stability features are
disabled. In an emergency evasive
maneuver, the ESC system will not engage
to assist in maintaining stability. “ESC
Off” mode is intended for off-highway or
off-road use only.

ESC Activation/Malfunction Indicator Light
And ESC OFF Indicator Light
The “ESC Activation/Malfunction
Indicator Light” in the instrument
cluster will come on when the igni-
tion is turned to the ON mode. It should go
out with the engine running. If the “ESC
Activation/Malfunction Indicator Light”
comes on continuously with the engine
running, a malfunction has been detected in
the ESC system. If this light remains on after
several ignition cycles, and the vehicle has
been driven several miles (kilometers) at
speeds greater than 30 mph (48 km/h), see an authorized dealer as soon as possible to
have the problem diagnosed and corrected.
The “ESC Activation/Malfunction Indicator
Light” (located in the instrument cluster)
starts to flash as soon as the tires lose trac -
tion and the ESC system becomes active.
The “ESC Activation/Malfunction Indicator
Light” also flashes when TCS is active. If the
“ESC Activation/Malfunction Indicator
Light” begins to flash during acceleration,
ease up on the accelerator and apply as little
throttle as possible. Be sure to adapt your
speed and driving to the prevailing road
conditions. NOTE:
The “ESC Activation/Malfunction Indi
-
cator Light” and the “ESC Off Indicator
Light” come on momentarily each time
the ignition is turned ON.
Each time the ignition is turned ON, the
ESC system will be on even if it was turned
off previously.
The ESC system will make buzzing or
clicking sounds when it is active. This is
normal; the sounds will stop when ESC
becomes inactive following the maneuver
that caused the ESC activation.
The “ESC Off Indicator Light” indi -
cates the customer has elected to
have the Electronic Stability Control
(ESC) in a reduced mode.
Hill Descent Control (HDC) — If Equipped
Hill Descent Control (Trailhawk) Hill Descent Control (HDC) is intended for
low speed off road driving while in 4L Range.
HDC maintains vehicle speed while
descending hills during various driving situa
-
tions. HDC controls vehicle speed by actively
controlling the brakes.
HDC has three states:
1. Off (feature is not enabled and will not activate).
2. Enabled (feature is enabled and ready but activation conditions are not met, or
driver is actively overriding with brake or
throttle application).
3. Active (feature is enabled and actively controlling vehicle speed).
Enabling HDC
HDC is enabled by pushing the HDC switch,
but the following conditions must also be
met to enable HDC:
Driveline is in 4L Range
Vehicle speed is below 7.5 mph (12 km/h)
Electric Park Brake (EPB) is released
Driver’s door is closed
2020_JEEP_M6_UG_UK.book Page 77

79
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.
Entering From The Side
Vehicles that move into your adjacent lanes
from either side of the vehicle.
