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.

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
SAFETY
78
Activating HDC
Once HDC is enabled, it will activate auto-
matically if driven down a grade of sufficient
magnitude (greater than approximately 8%).
The set speed for HDC is selectable by the
driver and can be adjusted within the thresh -
olds by using throttle or brake application.
Driver Override:
The driver may override HDC activation
speed with throttle or brake application at
anytime.
Deactivating HDC
HDC will be deactivated but remain available
if any of the following conditions occur:
Driver overrides HDC set speed with a
speed exceeding 7.5 mph (12 km/h) but
remains below 25 mph (40 km/h).
Vehicle is on a downhill grade of insuffi -
cient magnitude (less than approximately
8%), is on level ground, or is on an uphill
grade.
Vehicle is shifted to PARK. Disabling HDC
HDC will be deactivated and disabled if any
of the following conditions occur:
The driver pushes the HDC switch.
The driveline is shifted out of 4L Range.
The driver’s door opens.
The vehicle is driven greater than 25 mph
(40 km/h) (HDC exits immediately.)
Feedback To The Driver:
The instrument cluster has an HDC icon and
the HDC switch has an LED which offer feed -
back to the driver about the state HDC is in.
The cluster icon and switch lamp will illu -
minate and remain solid when HDC is
enabled or activated. This is the normal
operating condition for HDC.
The switch lamp will flash for several
seconds then extinguish when the driver
pushes the HDC switch when enable
conditions have not been met.
The Hill Descent Switch is located within the
Selec-Terrain knob in the upper right posi -
tion.
Hill Start Assist (HSA)
The Hill Start Assist (HSA) system is
designed to mitigate roll back from a
complete stop while on an incline. If the
driver releases the brake while stopped on an
incline, HSA will continue to hold the brake
pressure for a short period. If the driver does
not apply the throttle before this time
expires, the system will release brake pres -
sure and the vehicle will roll down the hill as
normal.
The following conditions must be met in
order for HSA to activate:
The feature must be enabled.
The vehicle must be stopped.
The park brake must be off.
The driver door must be closed.
The vehicle must be on a sufficient grade.
WARNING!
HDC is only intended to assist the driver in
controlling vehicle speed when descending
hills. The driver must remain attentive to
the driving conditions and is responsible
for maintaining a safe vehicle speed.
2020_JEEP_M6_UG_UK.book Page 78
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.

84
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.
