WARNING!(Continued)
•With the ESC switched off, the enhanced vehicle
stability offered by ESC is unavailable. In an emer-
gency evasive maneuver, the ESC system will not
engage to assist in maintaining stability. ESC “Full
Off” mode is only intended for off-highway or off-
road use.
•The Electronic Stability Control (ESC) cannot pre-
vent 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.
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 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” (lo-
cated in the instrument cluster) 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 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 Indicator 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” indicates the
customer has elected to have the Electronic Sta-
bility Control (ESC) in a reduced mode.
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 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. NOTE:
ERM is disabled anytime the ESC is in “Full Off”
mode (if equipped). Refer to “Electronic Stability Control
(ESC)” in this section for a complete explanation of the
available ESC modes.

SAFETY 173

NOTE:TSC cannot stop all trailers from swaying. Always
use caution when towing a trailer and follow the trailer
tongue weight recommendations. Refer to “Trailer Tow-
ing” 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.

If a Forward Collision Warning with Mitigation event
begins at a speed below 26 mph (42 km/h), the system may
provide the maximum or partial braking to mitigate the
potential forward collision. If the Forward Collision Warn-
ing with Mitigation event stops the vehicle completely, the
system will hold the vehicle at a standstill for two seconds
and then release the brakes.
When the system determines a collision with the vehicle in
front of you is no longer probable, the warning message
will be deactivated.NOTE:
•
The minimum speed for FCW activation is 1 mph
(2 km/h).
•
The FCW alerts may be triggered on objects other than
vehicles such as guard rails or sign posts based on the
course prediction. This is expected and is a part of normal
FCW activation and functionality.
• It is unsafe to test the FCW system. To prevent such
misuse of the system, after four Active Braking events
within an ignition cycle, the Active Braking portion of
FCW will be deactivated until the next ignition cycle.
• The FCW system is intended for on-road use only. If the
vehicle is taken off-road, the FCW system should be
deactivated to prevent unnecessary warnings to the
surroundings. If the vehicle enters 4WD Low Range or
ESC Full-Off Mode is active, the FCW system will be
automatically deactivated.

occupant’s mid-section so as to not activate the ALR. If the
ALR is activated, you will hear a clicking sound as the seat
belt retracts. Allow the webbing to retract completely in
this case and then carefully pull out only the amount of
webbing necessary to comfortably wrap around the occu-
pant’s mid-section. Slide the latch plate into the buckle
until you hear aclick.
In Automatic Locking Mode, the shoulder belt is automati-
cally pre-locked. The seat belt will still retract to remove
any slack in the shoulder belt. Use the Automatic Locking
Mode anytime a child restraint is installed in a seating
position that has a seat belt with this feature. Children 12
years old and under should always be properly restrained
in the rear seat of a vehicle with a rear seat.

WARNING!(Continued)
•Failure to replace the seat belt assembly could in-
crease the risk of injury in collisions.
• Do not use the Automatic Locking Mode to restrain
occupants who are wearing the seat belt or children
who are using booster seats. The locked mode is only
used to install rear-facing or forward-facing child
restraints that have a harness for restraining the
child.
Supplemental Active Head Restraints (AHR)
These head restraints are passive, deployable components,
and vehicles with this equipment cannot be readily iden-
tified by any markings, only through visual inspection of
the head restraint. The head restraint will be split in two
halves, with the front half being soft foam and trim, the
back half being decorative plastic. How The Active Head Restraints (AHR) Work
The Occupant Restraint Controller (ORC) determines
whether the severity or type of rear impact will require the
Active Head Restraints (AHR) to deploy. If a rear impact
requires deployment, both the driver and front passenger
seat AHRs will be deployed.
When AHRs deploy during a rear impact, the front half of
the head restraint extends forward to minimize the gap
between the back of the occupant’s head and the AHR. This
system is designed to help prevent or reduce the extent of
injuries to the driver and front passenger in certain types of
rear impacts.
NOTE:
The Active Head Restraints (AHR) may or may not
deploy in the event of a front or side impact. However, if
during a front impact, a secondary rear impact occurs, the
AHR may deploy based on the severity and type of the
impact.

SAFETY 209

NOTE:The system will automatically time out and the
ignition will cycle to the OFF mode after 30 minutes of
inactivity if the ignition is left in the ACC or RUN (engine
not running) mode and the transmission is in PARK.
ENGINE START/STOP Button Functions — With Driv-
er ’s Foot OFF The Brake Pedal (In PARK Or NEUTRAL
Position)
The ENGINE START/STOP button operates similar to an
ignition switch. It has three modes: OFF, ACC, and RUN.
To change the ignition modes without starting the vehicle
and use the accessories, follow these steps:
1. Starting with the ignition in the OFF mode,
2. Push the ENGINE START/STOP button once to place the ignition to the ACC mode (instrument cluster will
display “ACC”),
3. Push the ENGINE START/STOP button a second time to place the ignition to the RUN mode (instrument
cluster will display “ON/RUN”),
4. Push the ENGINE START/STOP button a third time to return the ignition to the OFF mode (instrument cluster
will display “OFF”).If Engine Fails To Start

WARNING!(Continued)
be in a vehicle unattended is dangerous for a number
of reasons. A child or others could be seriously or
fatally injured. Children should be warned not to
touch the parking brake, brake pedal or the trans-
mission gear selector.
• Do not leave the key fob in or near the vehicle (or in
a location accessible to children), and do not leave
the ignition in the ACC or ON/RUN mode. A child
could operate power windows, other controls, or
move the vehicle.

WARNING!(Continued)
that the transmission gear position indicator solidly
indicates PARK (P) without blinking. Ensure that the
vehicle is completely stopped, and the PARK posi-
tion is properly indicated, before exiting the vehicle.
• It is dangerous to shift out of PARK or NEUTRAL if
the engine speed is higher than idle speed. If your
foot is not firmly pressing the brake pedal, the
vehicle could accelerate quickly forward or in re-
verse. You could lose control of the vehicle and hit
someone or something. Only shift into gear when the
engine is idling normally and your foot is firmly
pressing the brake pedal.
• Unintended movement of a vehicle could injure
those in or near the vehicle. As with all vehicles, you
should never exit a vehicle while the engine is
running. Before exiting a vehicle, always come to a
complete stop, then apply the parking brake, shift
the transmission into PARK, and turn the ignition
OFF. When the ignition is in the OFF mode, the
transmission is locked in PARK, securing the vehicle
against unwanted movement.
(Continued)

CAUTION!(Continued)
•DO NOT race the engine when shifting from PARK
or NEUTRAL into another gear range, as this can
damage the drivetrain.
The following indicators should be used to ensure that you
have properly engaged the transmission into the PARK
position:
• When shifting into PARK, push the lock button on the
gear selector and firmly move the selector all the way
forward until it stops and is fully seated.
• Look at the transmission gear position display and
verify that it indicates the PARK position (P), and is not
blinking.
• With brake pedal released, verify that the gear selector
will not move out of PARK.
NOTE: If the gear selector cannot be moved to the PARK
position (when pushed forward), it is probably in the
AutoStick (+/-) position (beside the DRIVE position). In
AutoStick mode, the transmission gear (1, 2, 3, etc.) is
displayed in the instrument cluster. Move the gear selector
to the right (into the DRIVE [D] position) for access to
PARK, REVERSE, and NEUTRAL. REVERSE (R)
This range is for moving the vehicle backward. Shift into
REVERSE only after the vehicle has come to a complete
stop.
NEUTRAL (N)
Use this range when the vehicle is standing for prolonged
periods with the engine running. Apply the parking brake
and shift the transmission into PARK if you must exit the
vehicle.
