SAFETY FEATURES
ANTI-LOCK BRAKE SYSTEM (ABS)
The ABS provides increased vehicle stability and
brake performance 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.
The ABS is activated during braking when the
system detects one or more wheels are beginning
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 normal
characteristics when the ABS activates:
ABS motor noise or clicking sounds (you may
continue to hear for a short time after the stop)
Brake pedal pulsations
A slight drop of the brake pedal at the end of
the stopThe ABS is designed to function with the Original
Equipment Manufacturer (OEM) tires. Modification
may result in degraded ABS performance.
Anti-Lock Brake System (ABS) Warning
Light
The yellow ABS Warning Light will turn on when the
ignition is placed in the ON/RUN mode and may
stay on for as long as four seconds.
If the ABS Warning Light remains on or comes on
while driving, it indicates 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 ABS Warning Light is on.
If the ABS Warning Light is on, the brake system
should be serviced as soon as possible to restore
the benefits of Anti-lock Brakes. If the ABS Warning
WARNING!
The ABS contains sophisticated electronic
equipment that may be susceptible to interfer
-
ence caused by improperly installed or high
output radio transmitting equipment. This
interference can cause possible loss of
anti-lock braking capability. Installation of
such equipment should be performed by
qualified 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 efficiency 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 hydro -
planing.
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.

Light does not come on when the ignition is placed
in the ON/RUN mode, have the light repaired as
soon as possible.
ELECTRONIC BRAKE CONTROL (EBC)
S
YSTEM

Your vehicle is equipped with an advanced
Electronic Brake Control (EBC) system. This system
includes Anti-Lock Brake System (ABS), Brake Assist
System (BAS), Electronic Brake Force Distribution
(EBD), Electronic Roll Mitigation (ERM), Electronic
Stability Control (ESC), Hill Start Assist (HSA), and
Traction Control System (TCS). These systems work
together to enhance both vehicle stability and
control in various driving conditions.

Your vehicle may also be equipped with Dynamic
Steering Torque (DST), Hill Descent Control (HDC),
Rain Brake Support (RBS), Ready Alert Braking
(RAB), and Trailer Sway Control (TSC).
Brake Assist System (BAS)
The BAS is designed to optimize the vehicle’s
braking capability during emergency braking
maneuvers. The system detects an emergency
braking situation by sensing the rate and amount
of brake application and then applies optimum
pressure 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 placed in 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 indicates that the brake
system is not functioning properly and that
immediate service is required. If the Brake System
Warning Light does not come on when the ignition
is placed in the ON/RUN mode, have the light
repaired as soon as possible.
Dynamic Steering Torque (DST)
DST is a feature of the Electronic Stability Control
(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.
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)
EBD 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.
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.

(Continued)
Electronic Roll Mitigation (ERM)
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 applies the 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)
ESC enhances directional control and stability of
the vehicle under various driving conditions. ESC
corrects for oversteering or understeering of the
vehicle by applying the brake of the appropriate
wheel(s) to counteract the above conditions.
Engine power may also be reduced to help the
vehicle maintain the desired path.
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.
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. 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
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.
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 rollovers,
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.
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 condi
-
tions. ESC cannot prevent accidents, including
those resulting from excessive speed in turns,
driving on very slippery surfaces, or hydro -
planing. ESC also cannot prevent accidents
resulting from loss of vehicle control due to
inappropriate 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.

To turn ESC on again, momentarily push the ESC
OFF button. 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.
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 ignition is placed in 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 (km) 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
starts to flash as soon as the tires lose traction and
the ESC system becomes active. The ESC
Activation/Malfunction Indicator Light also flashes
when Traction Control System (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.
The ESC OFF Indicator Light indicates the
customer has elected to have the
Electronic Stability Control (ESC) in a
reduced mode.
NOTE:
The ESC Activation/Malfunction Indicator Light
and the ESC OFF Indicator Light come on
momentarily each time the ignition is placed in
the ON/RUN position.
Each time the ignition is placed in the ON/RUN
position, 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.
Emergency Stop Signal (ESS) —
If Equipped
The ESS activates the hazard lights at a faster than
normal speed when heavy brake pressure is
applied. ESS will only activate when the speed is
above 31 mph (50 km/h). The ESS operates
independently of other lamps, and will turn on and
off automatically. This indicates to others that the
vehicle is stopping quickly.
NOTE:
A warning light will illuminate within the instru -
ment cluster to inform the driver that the ESS
feature has been activated.
When towing a trailer, ESS will also activate the
rear indicator lights of the trailer.
Hill Descent Control (HDC) — If Equipped
Hill Descent Control (HDC) is intended for low
speed off-road driving while in 4WD Low. HDC
maintains vehicle speed while descending hills
during various driving situations. HDC controls
vehicle speed by actively controlling the brakes.
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. “Full Off” mode is intended for
off-highway or off-road use only.

SAFETY193
Hill Start Assist (HSA)
HSA 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 pressure 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 parking brake must be off.
The driver’s door must be closed.
The vehicle must be on a sufficient grade.
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 trans -
mission is in PARK or NEUTRAL.
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 see
Ú page 77.
Towing With HSA
Hill Start Assist (HSA) will also provide assistance
to mitigate roll back while towing a trailer.
Rain Brake Support (RBS)
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.
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 accel -
eration, 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.

194SAFETY
Ready Alert Braking (RAB)
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 Electronic Brake
Controller (EBC) system will prepare the brake
system for a panic stop.
Traction Control System (TCS)
The TCS monitors the amount of wheel spin for
each of the driven wheels. If wheel spin is
detected, the TCS may apply brake pressure to the
spinning wheel(s) and/or reduce vehicle power to
provide enhanced acceleration and stability. A
feature of the TCS, Brake Limited Differential (BLD)
functions similarly 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 reduced modes.
Trailer Sway Control (TSC)
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
excessively 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 recommendations
Úpage 154.
When TSC is functioning, the ESC Activation/
Malfunction Indicator Light will flash, the engine
power may be reduced and you may feel the
brakes being applied to individual 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) —
I
F EQUIPPED
The BSM system uses two radar sensors, located
inside the rear fascia/bumper, 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
rearview mirrors to let the driver know that the
system is operational. The BSM system sensors
operate when the vehicle is in any forward gear
and enters standby mode when the vehicle is
in PARK.
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.

22_MP_OM_EN_USC_t.book Page 194

198SAFETY
Blind Spot Modes
Blind Spot Alert has three selectable modes of
operation that are available in the Uconnect
system.
Blind Spot Alert Lights Only (Default Setting)
When operating in Lights Only 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 for the
duration of the chime.
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
time, both the visual and audible alerts will be
issued. In addition to the audible alert the radio
(if on) will also be 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 operating
mode when the vehicle is shut off. Each time the
vehicle is started the previously 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 indicators will remain illuminated until
blockage clearing conditions are met. First clear
the fascia/bumper area around the sensors of the
blockage. After removing the blockage, reset the
system by cycling the ignition from ON to OFF and
then back ON.
FORWARD COLLISION WARNING (FCW)
W
ITH MITIGATION — IF EQUIPPED
FCW 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 Electronic Brake
Controller (EBC), to calculate the probability of a
forward collision. When the system determines
that a forward collision 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.
