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.

WARNING!(Continued)
type of potential collision. The driver has the respon-
sibility to avoid a collision by controlling the vehicle
via braking and steering. Failure to follow this warn-
ing could lead to serious injury or death.
FCW Braking Status And Sensitivity
The FCW Sensitivity and Active Braking status are program-
mable through the Uconnect System. Refer to “Uconnect
Settings” in “Multimedia” for further information.
The default sensitivity of FCW is the “Medium” setting
and the system status is “Warning & Braking”. This allows
the system to warn the driver of a possible collision with
the vehicle in front using audible/visual warnings and it
applies autonomous braking.
Changing the FCW status to “Far” setting allows the system
to warn the driver of a possible collision with the vehicle in
front using audible/visual warning when the latter is at a
farther distance than Mediumsetting. This provides the
most reaction time to avoid a possible collision.
Changing the FCW status to the “Near” setting, allows the
system to warn the driver of a possible collision with the
vehicle in front when the distance between the vehicle in the front is much closer. This setting provides less reaction
time than the “Far” and “Medium” settings, which allows
for a more dynamic driving experience.
NOTE:
•
Changing the FCW status to “Only Warning” prevents
the system from providing limited active braking, or
additional brake support if the driver is not braking
adequately in the event of a potential frontal collision,
but maintains the audible and visual warnings.
• Changing the FCW status to “Off” prevents the system
from providing autonomous braking, or additional
brake support if the driver is not braking adequately in
the event of a potential frontal collision.
• The system will retain the last setting selected by the
driver after ignition shut down.
• FCW may not react to irrelevant objects such as over-
head objects, ground reflections, objects not in the path
of the vehicle, stationary objects that are far away,
oncoming traffic, or leading vehicles with the same or
higher rate of speed.
• FCW will be disabled like ACC, with the unavailable
screens.
190 SAFETY

•The Air Bag Warning Light does not come on during the
four to eight seconds when the ignition switch is first in
the ON/RUN position.
• The Air Bag Warning Light remains on after the four to
eight-second interval.
• The Air Bag Warning Light comes on intermittently or
remains on while driving.
NOTE:
If the speedometer, tachometer, or any engine related
gauges are not working, the Occupant Restraint Controller
(ORC) may also be disabled. In this condition the air bags
may not be ready to inflate for your protection. Have an
authorized dealer service the air bag system immediately.

tank before resetting the system and starting the engine.
If there are no fuel leaks or damage to the vehicle electrical
devices (e.g. headlights) after an accident, reset the system
by following the procedure described below.
Enhanced Accident Response System Reset
Procedure
In order to reset the Enhanced Accident Response System
functions after an event, the ignition switch must be
changed from ignition START or ON/RUN to ignition OFF.
Carefully check the vehicle for fuel leaks in the engine
compartment and on the ground near the engine compart-
ment and fuel tank before resetting the system and starting
the engine.
Maintaining Your Air Bag System

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.

Gear Ranges
Do not depress the accelerator pedal when shifting from
PARK or NEUTRAL into another gear range.
NOTE:After selecting any gear range, wait a moment to
allow the selected gear to engage before accelerating. This
is especially important when the engine is cold.
PARK (P)
This range supplements the parking brake by locking the
transmission. The engine can be started in this range.
Never attempt to use PARK while the vehicle is in motion.
Apply the parking brake when exiting the vehicle in this
range.
When parking on a level surface, you may shift the
transmission into PARK first, and then apply the parking
brake.
When parking on a hill, apply the parking brake before
shifting the transmission to PARK. As an added precau-
tion, turn the front wheels toward the curb on a downhill
grade and away from the curb on an uphill grade. When exiting the vehicle, always:
•
Apply the parking brake,
• Shift the transmission into PARK,
• Turn the ignition OFF and,
• Remove the key fob from the vehicle.
NOTE: On four-wheel drive vehicles be sure that the
transfer case is in a drive position.

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.

•The Normal (Fixed Speed) Cruise Control on/off button
is pushed.
• The ignition is turned OFF.
• You switch to Four-Wheel Drive Low.
To Resume
If there is a set speed in memory push the RES (resume)
button and then remove your foot from the accelerator
pedal. The instrument cluster display will display the last
set speed.
NOTE:
•If your vehicle stays at standstill for longer than two
seconds, then the system will cancel and the brake force
will be ramped-out. The driver will have to apply the
brakes to keep the vehicle at a standstill.
• ACC cannot be resumed if there is a stationary vehicle
in-front of your vehicle in close proximity.

the top of the screen. After five seconds this note will
disappear. The ParkView camera is located on the rear of
the vehicle above the rear license plate.
When the vehicle is shifted out of REVERSE (with camera
delay turned off), the rear camera mode is exited and the
navigation or audio screen appears again.
When the vehicle is shifted out of REVERSE (with camera
delay turned on), the rear view image with dynamic grid
lines will be displayed for up to 10 seconds after shifting
out of REVERSE unless the forward vehicle speed exceeds
8 mph (13 km/h), the transmission is shifted into PARK or
the ignition is switched to the OFF position.
NOTE:The ParkView Rear Back Up Camera has program-
mable modes of operation that may be selected through the
Uconnect System. Refer to “Uconnect Settings” in “Multi-
media” for further information.
When enabled, active guide lines are overlaid on the image
to illustrate the width of the vehicle and its projected
backup path based on the steering wheel position. A
dashed center line overlay indicates the center of the
vehicle to assist with parking or aligning to a hitch/ receiver. Different colored zones indicate the distance to the
rear of the vehicle. The following table shows the approxi-
mate distances for each zone:
