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 the Anti-Lock Brake System
(ABS) before the front axle.
Electronic Roll Mitigation (ERM)
The ERM system 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, 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 posi -
tion.
Understeer — when the vehicle is turning less
than appropriate for the steering wheel posi -
tion.
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 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.

Full Off — If Equipped
This mode is intended for off-highway or
off-road use only and should not be used on any
public roadways. In this mode, TCS and ESC
features are turned off. To enter the “Full Off”
mode, push and hold the ESC OFF switch for five
seconds while the vehicle is stopped with the
engine running. After five seconds, a chime will
sound, the ESC OFF Indicator Light will
illuminate, and the “ESC OFF” message will
display in the instrument cluster. To turn ESC on
again, momentarily push the ESC OFF switch.NOTE:
System may switch from ESC “Full Off” to
“Partial Off” mode when vehicle exceeds a
predetermined speed. When the vehicle speed
slows below the predetermined speed the
system will return to ESC “Full Off”.
ESC modes may also be affected by drive
modes (if equipped).
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/RUN 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.
WARNING!
When in “Partial Off” mode, the TCS func -
tionality of ESC, (except for the limited slip
feature described in the TCS section), has
been disabled and the “ESC OFF Indicator
Light” will be illuminated. 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!
In the ESC “Full Off” mode, the engine
torque reduction and stability features are
disabled. Therefore, enhanced vehicle
stability offered by the ESC system is
unavailable. In an emergency evasive
maneuver, the ESC system will not engage
to assist in maintaining stability. ESC “Full
Off” mode is intended for off-highway or
off-road use only.
The Electronic Stability Control (ESC)
cannot prevent the natural laws of physics
from acting on the vehicle, nor can it
increase the traction afforded by prevailing
road conditions. ESC cannot prevent all
accidents, including those resulting from
excessive speed in turns, driving on very
slippery surfaces, or hydroplaning. ESC also
cannot prevent collisions.

318SAFETY
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 Control System will prepare the brake
system for a panic stop.
Traction Control System (TCS)
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
spinning wheel(s) and/or reduce engine 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 engine torque to be applied to the
wheel that is not spinning. BLD may remain
enabled even if TCS and Electronic Stability
Control (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.
NOTE:
TSC cannot stop all trailers from swaying.
Always use caution when towing a trailer and
follow the trailer tongue weight recommenda -
tions Ú page 214.
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) — IF
E
QUIPPED
BSM uses two radar sensors, located inside the
taillights, 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
or REVERSE 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.

warning limit, upon the next ignition switch
cycle, the Tire Pressure Monitoring System
(TPMS) Warning Light and a “LOW TIRE”
message will remain on and a chime will
sound. In addition, the graphic in the instru -
ment cluster will still display a pressure value
in a different color and an “Inflate to XX”
message.
After driving the vehicle for up to 20 minutes
above 15 mph (24 km/h), the Tire Pressure
Monitoring System (TPMS) Warning Light will
flash on and off for 75 seconds and then
remain on solid. In addition, the instrument
cluster will display a "SERVICE TPMS
SYSTEM" message for a minimum of five
seconds and then display dashes (--) in place
of the pressure value.
For each subsequent ignition switch cycle, a
chime will sound, the Tire Pressure Moni -
toring System (TPMS) Warning Light will flash
on and off for 75 seconds and then remain
on solid, and the instrument cluster will
display a "SERVICE TPMS SYSTEM" message
for a minimum of five seconds and then
display dashes (--) in place of the pressure
value.
Once you repair or replace the original road
tire and reinstall it on the vehicle in place of
the non-matching full size spare or compact
spare, the TPMS will update automatically. In
addition, the Tire Pressure Monitoring
System (TPMS) Warning Light will turn off and
the graphic in the instrument cluster will
display a new pressure value instead of
dashes (--), as long as no tire pressure is
below the low-pressure warning limit in any of
the four active road tires. The vehicle may
need to be driven for up to 20 minutes above
15 mph (24 km/h) in order for the TPMS to
receive this information.
Tire Fill Alert
This feature notifies the user when the placard
tire pressure is attained while inflating or
deflating the tire.
You may choose to disable or enable the Tire Fill
Alert feature through use of the Uconnect
Settings in the radio.
NOTE:
Only one tire can be filled at a time when
using the Tire Fill Alert system.
The Tire Fill Alert feature cannot be entered if
an existing TPMS fault is set to “active” or if
the system is in deactivation mode (if
equipped).
The system will be activated when a positive
increase in tire pressure is detected by the
TPMS while inflating the tire. The ignition must
be in the RUN mode, with the transmission in
PARK.
NOTE:
It is not required to have the engine running to
enter Tire Fill Alert mode.
The hazard lamps will come on to confirm the
vehicle is in Tire Fill Alert mode.
When Tire Fill Alert mode is entered, the tire
pressure display screen will be displayed in the
instrument cluster.
If the hazard lamps do not come on while
inflating the tire, the TPMS sensor may be out of
range preventing the TPMS sensor signal from
being received. In this case, the vehicle may
need to be moved either forward or backward
slightly to exit the null spot.
