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

WARNING!
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.
Electronic Stability Control (ESC)
This system 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 assist in
counteracting the oversteer or understeer
condition. 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
Activation/Malfunction Indicator Light” be-
gins 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!
•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 con-
ditions. ESC cannot prevent accidents, in-
cluding those resulting from excessive
speed in turns, driving on very slippery
surfaces, or hydroplaning. ESC also cannot
prevent accidents resulting from loss of
WARNING!
vehicle control due to inappropriate driver
input for the conditions. Only a safe, atten-
tive, and skillful driver can prevent acci-
dents. The capabilities of an ESC equipped
vehicle must never be exploited in a reck-
less or dangerous manner which could jeop-
ardize the user’s safety or the safety of
others.
• Vehicle modifications, or failure to prop-
erly maintain your vehicle, may change
the handling characteristics of your ve-
hicle, and may negatively affect the per-
formance of the ESC system. Changes to
the steering system, suspension, brak-
ing system, tire type and size or wheel
size may adversely affect ESC perfor-
mance. Improperly inflated and un-
evenly worn tires may also degrade ESC
performance. Any vehicle modification
or poor vehicle maintenance that re-
duces the effectiveness of the ESC sys-
tem can increase the risk of loss of
vehicle control, vehicle rollover, per-
sonal injury and death.

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.
ESC OFF Button
SAFETY
80

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.

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.
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, mo-
torcycles, etc.) that enter the blind spot
zones from the rear/front/side of the vehicle.
Rear Detection Zones

• Seat Belt Pretensioners
• Seat Track Position Sensors
If A Deployment Occurs
The front air bags are designed to deflate
immediately after deployment.
NOTE:
Front and/or side air bags will not deploy in all
collisions. This does not mean something is
wrong with the air bag system.
If you do have a collision which deploys the
air bags, any or all of the following may occur:
• The air bag material may sometimes cause
abrasions and/or skin reddening to the oc-
cupants as the air bags deploy and unfold.
The abrasions are similar to friction rope
burns or those you might get sliding along a
carpet or gymnasium floor. They are not
caused by contact with chemicals. They are
not permanent and normally heal quickly.
However, if you haven’t healed significantly
within a few days, or if you have any blis-
tering, see your doctor immediately.
• As the air bags deflate, you may see some
smoke-like particles. The particles are a
normal by-product of the process that gen-erates the non-toxic gas used for air bag
inflation. These airborne particles may irri-
tate the skin, eyes, nose, or throat. If you
have skin or eye irritation, rinse the area
with cool water. For nose or throat irritation,
move to fresh air. If the irritation continues,
see your doctor. If these particles settle on
your clothing, follow the garment manufac-
turer’s instructions for cleaning.
Do not drive your vehicle after the air bags
have deployed. If you are involved in another
collision, the air bags will not be in place to
protect you.
WARNING!
Deployed air bags and seat belt preten-
sioners cannot protect you in another col-
lision. Have the air bags, seat belt preten-
sioners, and the seat belt retractor
assemblies replaced by an authorized
dealer immediately. Also, have the Occu-
pant Restraint Controller System serviced
as well.NOTE:
• Air bag covers may not be obvious in the
interior trim, but they will open during air
bag deployment.
• After any collision, the vehicle should be
taken to an authorized dealer immediately.
Enhanced Accident Response System
In the event of an impact, if the communica-
tion network remains intact, and the power
remains intact, depending on the nature of
the event, the ORC will determine whether to
have the Enhanced Accident Response Sys-
tem perform the following functions:
• Cut off fuel to the engine.
• Flash hazard lights as long as the battery
has power or until the hazard light button is
pressed. The hazard lights can be deacti-
vated by pressing the hazard light button.
• Turn on the interior lights, which remain on
as long as the battery has power or for 15
minutes from the intervention of the En-
hanced Accident Response System.
• Unlock the power door locks.
117

• Turn off the Gasoline Fuel Pump Heater (if
equipped) or the Diesel Fuel Filter Heater
(if equipped).
• Turn off the HVAC Blower Motor.
• Close the HVAC Circulation Door.
Enhanced Accident Response System Reset
Procedure
After the event occurs, when the system is
active, a message regarding fuel cutoff is
displayed. Turn the ignition switch from igni-
tion AVV/START or MAR/ACC/ON/RUN to ig-
nition STOP/OFF/LOCK. Carefully check the
vehicle for fuel leaks in the engine compart-
ment and on the ground near the engine
compartment and fuel tank before resetting
the system and starting the engine.
Depending on the nature of the event the left
and right turn signal lights, located in the
instrument panel, may both be blinking and
will continue to blink. In order to move your
vehicle to the side of the road, you must
follow the system reset procedure.

Maintaining Your Air Bag System
WARNING!
• Modifications to any part of the air bag
system could cause it to fail when you
need it. You could be injured if the air
bag system is not there to protect you.
WARNING!
Do not modify the components or wiring,
including adding any kind of badges or
stickers to the steering wheel hub trim
cover or the upper right side of the in-
strument panel. Do not modify the front
bumper, vehicle body structure, or add
aftermarket side steps or running
boards.
• It is dangerous to try to repair any part of
the air bag system yourself. Be sure to
tell anyone who works on your vehicle
that it has an air bag system.
• Do not attempt to modify any part of your
air bag system. The air bag may inflate
accidentally or may not function prop-
erly if modifications are made. Take your
vehicle to an authorized dealer for any
air bag system service. If your seat, in-
cluding your trim cover and cushion,
needs to be serviced in any way (includ-
ing removal or loosening/tightening of
seat attachment bolts), take the vehicle
to your authorized dealer. Only manufac-
turer approved seat accessories may be
used. If it is necessary to modify the air

Event Data Recorder (EDR)
This vehicle is equipped with an event data
recorder (EDR). The main purpose of an EDR
is to record, in certain crash or near crash-like
situations, such as an air bag deployment or
hitting a road obstacle, data that will assist in
understanding how a vehicle’s systems per-
formed. The EDR is designed to record data
related to vehicle dynamics and safety sys-
tems for a short period of time, typically
30 seconds or less. The EDR in this vehicle is
designed to record such data as:
• How various systems in your vehicle were
operating;
• Whether or not the driver and passenger
safety belts were buckled/fastened;
• How far (if at all) the driver was depressing
the accelerator and/or brake pedal; and,
• How fast the vehicle was traveling.
