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 en-
sure 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.
WARNING!
• The ABS contains sophisticated elec-
tronic equipment that may be suscep-
tible to interference caused by improp-
erly 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
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
WARNING!
condition of the vehicle brakes and tires
or the traction afforded.
• The ABS cannot prevent collisions, in-
cluding 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.
ABS is designed to function with the OEM
tires. Modification may result in degraded
ABS performance.
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” re-
mains 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
SAFETY

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 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 turned to the
ON/RUN mode, have the light repaired as
soon as possible.
Dynamic Steering Torque (DST)
Dynamic Steering Torque is a feature of the
ESC and Electric Power Steering (EPS) mod-
ules that provides torque at the steering
wheel for certain driving conditions in which
the ESC module is detecting vehicle instabil-
ity. The torque that the steering wheel re-
ceives is only meant to help the driver realize
optimal steering behavior in order to reach/maintain vehicle stability. The only notifica-
tion 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)
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 be-
fore the front axle.
Electronic Roll Mitigation (ERM)
This 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 vehi-
cle’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.
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

ESC Operating Modes
NOTE:
Depending upon model and mode of opera-
tion, the ESC system may have multiple op-
erating modes.ESC On
This is the normal operating mode for the
ESC. Whenever the vehicle is started, the
ESC system will be in this mode. This mode
should be used for most driving conditions.
Alternate ESC modes should only be used for
specific reasons as noted in the following
paragraphs.
Partial Off
The “Partial Off” mode is intended for times
when a more spirited driving experience is
desired. This mode may modify TCS and ESC
thresholds for activation, which allows for
more wheel spin than normally allowed. This
mode may be useful if the vehicle becomes
stuck.
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 Indicator 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.
WARNING!
• When in “Partial Off” mode, the TCS
functionality of ESC, (except for the lim-
ited 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 sta-
bility offered by the ESC system is re-
duced.
• Trailer Sway control (TSC) is disabled
when the ESC system is in the “Partial
Off” mode.

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 illuminated 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 se-
lector 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!
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 maintain-
ing 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 ignition is turned tothe ON mode. It should go out with the
engine running. If the “ESC Activation/
Malfunction Indicator Light” comes on con-
tinuously with the engine running, a malfunc-
tion has been detected in the ESC system. If
this light remains on after several ignition
cycles, and the vehicle has been driven sev-
eral miles (kilometers) at speeds greater than
30 mph (48 km/h), see your authorized
dealer as soon as possible to have the prob-
lem 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 con-
ditions.
81

NOTE:
• The “ESC Activation/Malfunction Indicator
Light” and the “ESC OFF Indicator Light”
come on momentarily each time the igni-
tion 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 click-
ing 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”
indicates the customer has
elected to have the Electronic
Stability Control (ESC) in a re-
duced mode.Hill Descent Control (HDC) — If Equipped
HDC is intended for low speed off road driv-
ing while in 4WD Low Range. HDC maintains
vehicle speed while descending hills during
various driving situations. HDC controls ve-
hicle 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 4WD Low Range.
• Vehicle speed is below 7.5 mph (12 km/h).
• Electric Park Brake (EPB) is released.
• Driver’s door is closed.

Rain Brake Support (RBS)
Rain Brake Support may improve braking
performance in wet conditions. It will periodi-
cally apply a small amount of brake pressure
to remove any water buildup on the front
brake rotors. It functions when the wind-
shield wipers are in LO or HI speed. When
Rain Brake Support is active, there is no
notification to the driver and no driver inter-
action is required.
Ready Alert Braking (RAB)
Ready Alert Braking may reduce the time
required to reach full braking during emer-
gency 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.
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 recog-
nized.NOTE:
TSC cannot stop all trailers from swaying.
Always use caution when towing a trailer and
follow the trailer tongue weight recommenda-
tions. Refer to “Trailer Towing” in “Starting
And Operating” for further information.
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.
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.
