— 4WD Lock Indicator Light
This light alerts the driver that the vehicle is in the
four-wheel drive LOCK mode. The front and rear drivesh -
afts are mechanically locked together, forcing the front and
rear wheels to rotate at the same speed.
Refer to “Four-Wheel Drive Operation” in “Starting And
Operating” for further information on four-wheel drive
operation and proper use.
— 4WD Low Indicator Light — If Equipped
This light alerts the driver that the vehicle is in the
four-wheel drive LOW mode. The front and rear driveshafts
are mechanically locked together forcing the front and rear
wheels to rotate at the same speed. Low range provides a
greater gear reduction ratio to provide increased torque at
the wheels.
Refer to “Four-Wheel Drive Operation — If Equipped” in
“Starting And Operating” for further information on
four-wheel drive operation and proper use.
— 4WD High Indicator Light — If Equipped
This light alerts the driver that the vehicle is in the
four-wheel drive HIGH mode. The front and rear driveshafts are mechanically locked together forcing the front and rear
wheels to rotate at the same speed.
— NEUTRAL Indicator Light — If Equipped
This light alerts the driver that the 4WD power transfer case
is in the NEUTRAL mode and the front and rear driveshafts
are disengaged from the powertrain.

Towing With HSA
HSA will also provide assistance to mitigate roll back while
towing a trailer.Disabling And Enabling HSA
This feature can be turned on or turned off. To change the
current setting, proceed as follows:
• If disabling HSA using your instrument cluster display,
refer to “Instrument Cluster Display” in “Getting To Know
Your Instrument Panel” for further information.
• If disabling HSA using Uconnect Settings, refer to “Ucon -
nect Settings” in “Multimedia” for further information.
For vehicles not equipped with an instrument cluster
display, perform the following steps:
1. Center the steering wheel (front wheels pointing straight forward).
2. Shift the transmission into PARK.
3. Apply the parking brake.
4. Start the engine.
5. Rotate the steering wheel slightly more than one-half turn to the left.
WARNING!
• If you use a trailer brake controller with your trailer, the trailer brakes may be activated and deactivated with
the brake switch. If so, there may not be enough brake
pressure to hold both the vehicle and the trailer on a
hill when the brake pedal is released. In order to avoid
rolling down an incline while resuming acceleration,
manually activate the trailer brake or apply more
vehicle brake pressure prior to releasing the brake
pedal.
• HSA is not a parking brake. Always apply the parking brake fully when exiting your vehicle. Also, be certain
to place the transmission in PARK.
• Failure to follow these warnings can result in a colli -
sion or serious personal injury.

SAFETY 203
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 so
equipped.WARNING!
• In the ESC “Full Off” mode, the engine torque reduc -
tion 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 hydro -
planing. ESC also cannot prevent collisions.

216 SAFETY
Forward Collision Warning (FCW) With Mitigation — If
Equipped
The Forward Collision Warning (FCW) system provides the
driver with audible, visual warnings (within the instrument
cluster display), and may apply a haptic warning in the form
of a brake jerk, to warn the driver when it detects a potential
frontal collision. The warnings are intended to provide the
driver with enough time to react, avoid or mitigate the
potential collision.
NOTE:
FCW monitors the information from the forward looking
sensors as well as Electronic Brake Controller (EBC), to calcu-
late the probability of a forward collision. When the system
determines that a forward collision is probable, the driver
will be provided with audible and visual warnings as well as
a possible haptic warning in the form of a brake jerk.
If the driver does not take action based upon these progres-
sive warnings, then the system will provide a limited level of
active braking to help slow the vehicle and mitigate the
potential forward collision. If the driver reacts to the warn -
ings by braking and the system determines that the driver
intends to avoid the collision by braking but has not applied
sufficient brake force, the system will compensate and
provide additional brake force as required. If a FCW with Mitigation event begins at a speed below
32 mph (52 km/h), the system may provide the maximum
braking possible to mitigate the potential forward collision.
If the Forward Collision Warning with Mitigation event
stops the vehicle completely, the system will hold the vehicle
at standstill for two seconds and then release the brakes.
FCW Message
When the system determines a collision with the vehicle in
front of you is no longer probable, the warning message will
be deactivated.

SAFETY 217
NOTE:

• The minimum speed for FCW activation is 3 mph (5 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 a
key cycle, the Active Braking portion of FCW will be deac -
tivated until the next key cycle.
• The FCW system is intended for on-road use only. If the vehicle is taken off-road, the FCW system should be deac -
tivated to prevent unnecessary warnings to the surround -
ings.
• FCW may not react to irrelevant objects such as overhead 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. Turning FCW On or Off
The FCW button is located in the Uconnect display in the
control settings. Refer to “Uconnect Settings” in “Multi
-
media” in the Owner's Manual for further information.
• To turn the FCW system on, press the forward collision button once to turn the system on.
• To turn the FCW system off, press the forward collision button once to turn the system off.
NOTE:
• When the FCW is “on”, this allows the system to warn the driver of a possible collision with the vehicle in front.
• When the FCW is “off” prevents the system from warning the driver of a possible collision with the vehicle in front.
If the FCW is set to “off”, “FCW OFF" will be displayed in
the instrument cluster display.WARNING!
Forward Collision Warning (FCW) is not intended to
avoid a collision on its own, nor can FCW detect every
type of potential collision. The driver has the
responsibility to avoid a collision by controlling the
vehicle via braking and steering. Failure to follow this
warning could lead to serious injury or death.

SAFETY 219
FCW Limited Warning
If the instrument cluster displays “ACC/FCW Limited Func-
tionality” or “ACC/FCW Limited Functionality Clean Front
Windshield” momentarily, there may be a condition that
limits FCW functionality. Although the vehicle is still driv -
able under normal conditions, the active braking may not be
fully available. Once the condition that limited the system
performance is no longer present, the system will return to
its full performance state. If the problem persists, see an
authorized dealer.
Service FCW Warning
If the system turns off, and the instrument cluster displays:
• ACC/FCW Unavailable Service Required
• Cruise/FCW Unavailable Service Required
This indicates there is an internal system fault. Although the
vehicle is still drivable under normal conditions, have the
system checked by an authorized dealer. General Information

220 SAFETY
Tire Pressure Monitoring System (TPMS)
The Tire Pressure Monitor System (TPMS) will warn the
driver of a low tire pressure based on the vehicle recom-
mended cold placard pressure.
NOTE:
The TPMS Warning Light will illuminate in the instrument
cluster and a chime will sound when tire pressure is low in
one or more of the four active road tires. In addition, the
instrument cluster will display a graphic showing the pres -
sure values of each tire with the low tire pressure values in a
different color, or the Uconnect radio will display a TPMS
message, when this occurs you must increase the tire pres -
sure to the recommended cold placard pressure in order for
the TPMS Warning Light to turn off.
The tire pressure will vary with temperature by about 1 psi
(7 kPa) for every 12°F (6.5°C). This means that when the
outside temperature decreases, the tire pressure will
decrease. Tire pressure should always be set based on cold
inflation tire pressure. This is defined as the tire pressure
after the vehicle has not been driven for at least three hours,
or driven less than 1 mile (1.6 km) after a three hour period.
The cold tire inflation pressure must not exceed the
maximum inflation pressure molded into the tire sidewall.
Refer to “Tires” in “Servicing And Maintenance” for infor -mation on how to properly inflate the vehicle’s tires. The tire
pressure will also increase as the vehicle is driven - this is
normal and there should be no adjustment for this increased
pressure.
The TPMS will warn the driver of a low tire pressure if the
tire pressure falls below the low-pressure warning limit for
any reason, including low temperature effects and natural
pressure loss through the tire.
The TPMS will continue to warn the driver of low tire pres
-
sure as long as the condition exists, and will not turn off until
the tire pressure is at or above the recommended cold
placard pressure. Once the low TPMS Warning Light illumi -
nates, you must increase the tire pressure to the recom -
mended cold placard pressure in order for the TPMS
Warning Light to turn off. The system will automatically
update and the TPMS Warning Light will turn off once the
system receives the updated tire pressures. 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.
NOTE:
When filling warm tires, the tire pressure may need to be
increased up to an additional 4 psi (28 kPa) above the recom -
mended cold placard pressure in order to turn the TPMS
Warning Light off.

222 SAFETY
• The TPMS is not a substitute for proper tire maintenance,and it is the driver’s responsibility to maintain correct tire
pressure using an accurate tire pressure gauge, even if
under-inflation has not reached the level to trigger illumi -
nation of the TPMS Warning Light.
• Seasonal temperature changes will affect tire pressure, and the TPMS will monitor the actual tire pressure in the tire.
Example: Tire Pressure Monitor Display
The Tire Pressure Monitor System (TPMS) uses wireless
technology with wheel rim mounted electronic sensors to
monitor tire pressure levels. Sensors, mounted to each wheel as part of the valve stem, transmit tire pressure readings to
the receiver module.
NOTE:
It is particularly important for you to check the tire pressure
in all of the tires on your vehicle monthly and to maintain the
proper pressure.
The TPMS consists of the following components:
• Receiver module
• Four tire pressure monitoring sensors
• Various tire pressure monitoring system messages, which
display in the instrument cluster
• Tire Pressure Monitoring System Warning Light
Tire Pressure Monitoring Low Pressure Warnings
The “Tire Pressure Monitoring Telltale Light” will
illuminate in the instrument cluster and a chime will
sound when tire pressure is low in one or more of the
four active road tires. In addition, the instrument cluster will
display a graphic showing the pressure values of each tire
with the low tire pressure values in a different color. An
"Inflate to XX" message will also be displayed.
