Partial Off – Two Wheel Drive Vehicles And Four Wheel
Drive Vehicles In 2WD And 4WD High Range
The “Partial Off” mode is intended for driving in deep
snow, sand, or gravel. This mode raises the threshold for
TCS and ESC activation, which allows for more wheel spin
than what ESC normally allows.
To enter the “Partial Off” mode, momentarily push the
“ESC Off” button and the ESC Off indicator light will
illuminate. To turn the ESC on again, momentarily pushthe ESC OFF button and the ESC Off indicator light will
turn off. This will restore the normal “ESC On” mode of
operation.
NOTE:
To improve the vehicle’s traction when driving
with snow chains, or when starting off in deep snow, sand,
or gravel, it may be desirable to switch to the “Partial Off”
mode by momentarily pushing the “ESC Off” button. 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 limited slip feature described
in the TCS section), has been disabled and the “ESC
Off Indicator Light” will be illuminated. When in
“Partial Off” mode, the engine power reduction
feature of TCS is disabled, and the enhanced vehicle
stability offered by the ESC system is reduced.
• Trailer Sway control (TSC) is disabled when the ESC
system is in the “Partial Off” mode.

174 SAFETY
Full Off – Four-Wheel Drive Vehicles In 4WD High And
4WD Low Range
The “Full Off” mode is intended for off-highway and
off-road use when ESC stability features could inhibit
vehicle maneuverability due to trail conditions. The “ESC
Off” button is located in the lower switch bank above the
climate control panel. To enter “Full Off” mode, push and
hold the “ESC Off” button for five seconds while the
vehicle is stopped with the engine running. After five
seconds, the ESC Off indicator light will illuminate and an
“ESC Off” message will appear in the odometer.
In this mode, ESC and TCS are turned off (except for the
“limited slip” feature described in the TCS section) until
the vehicle reaches a speed of 40 mph (64 km/h). At speeds
over 40 mph (64 km/h), the system automatically switches
to “Partial Off” mode, described above. When the vehicle
speed returns to less than 35 mph (56 km/h), the ESC
system will return to “Full Off” mode. The ESC OFF
indicator light is always illuminated when ESC is off. To
turn ESC on again, momentarily push the “ESC Off”
button. This will restore the normal “ESC On” mode of
operation.NOTE:
With the ESC switched off, the enhanced vehicle
stability offered by ESC is unavailable. In an emergency
evasive maneuver, the ESC system will not engage to assist
in maintaining stability. “Full Off” mode is only intended
for off-highway or off-road use.
NOTE:
• “Full Off” is the only operating mode for ESC in 4WD
LOW range. The ESC system will be in this mode
whenever the vehicle is started in 4WD LOW range or
the power transfer unit is shifted into 4WD LOW range.
• The “ESC OFF” message will display and a chime will
sound when the gear selector is moved from any posi-
tion to the PARK position and then moved out of the
PARK position. This will occur even if the message was
cleared previously.
Selec-Terrain — If Equipped
On models equipped with Selec-Terrain, the activation of
some driving modes provide partial off or full off of some
active safety systems in order to optimize performance in
specific modes.
Partial or full off of the active safety systems will be
indicated by a light in the instrument cluster.

SAFETY 175
InSAND andMUD, the active safety systems are
partially disabled and put in place to ensure maximum
performance in the specific mode of operation. However,
you can reactivate them completely at any time by pushing
the ESC button.
NOTE: In 4WD LOW, the active safety systems are com-
pletely bypassed in order to ensure maximum off-road
performance.
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 switch is turned to the ON
position. It should go out with the engine run-
ning. If the “ESC Activation/Malfunction Indicator Light”
comes on continuously with the engine running, a mal-
function 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 your 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 Traction Control System 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 switch 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.
TheESC OFF Indicator Light indicates the
Electronic Stability Control (ESC) is partially off
or full off.
The ESC OFF switch is located in the center console.
176 SAFETY
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 will only
intervene during very severe or evasive driving maneu-
vers. ERM can only reduce the chance of wheel lift occur-
ring 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. Refer to Electronic Stability Control (ESC) in this
section for a complete explanation of the available ESC
modes.
WARNING!
Many factors, such as vehicle loading, road conditions,
and driving conditions, influence the chance that
(Continued)
WARNING! (Continued)
wheel lift or rollover may occur. Electronic Roll Miti-
gation (ERM) cannot prevent all wheel lift or rollovers,
especially those that involve leaving the roadway or
striking objects or other vehicles. The capabilities 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.
Traction Control System (TCS)
This system monitors the amount of wheel spin of each of
the driven wheels. If wheel spin is detected, brake pressure
is applied to the slipping wheel(s) and engine power is
reduced to provide enhanced acceleration and stability. A
feature of the TCS system, Brake Limited Differential
(BLD), functions similar to a limited slip differential and
controls the wheel spin across a driven axle. If one wheel
on a driven axle is spinning faster than the other, the
system will apply the brake of the spinning wheel. This
will allow more engine torque to be applied to the wheel
that is not spinning. This feature remains active even if TCS
and ESC are in the “Partial Off” mode or the “Full Off”
mode. Refer to “Electronic Stability Control (ESC)” in this
section for further information.

SAFETY 177
NOTE:
•FCW monitors the information from the forward look-
ing sensors as well as the Electronic Brake Controller
(EBC), to calculate 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 and may provide a brake jerk warning.
• If the driver does not take action based upon these
progressive 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 warnings 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.
Vehicles With A Manual Transmission: After the end of
the intervention of automatic braking, the engine could
stall, unless the driver can depress the clutch pedal.
Vehicles With Automatic Transmission: After the end of
the intervention of automatic braking, the transmission
may remain in last gear stored: therefore the vehicle could
lurch forward, once the brakes release a few seconds later.
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.
If a Forward Collision Warning with Mitigation event
begins at a speed below 20 mph (32 km/h), the system may
provide the maximum braking possible 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 standstill for two seconds
and then release the brakes.
FCW Message
5
SAFETY 189
•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 status of the system is only possible with the
vehicle at a complete stop.
NOTE: The FCW system state is not kept in memory from
one ignition position to the next. If the system is turned off,
it will turn on when the vehicle is restarted.
Changing FCW Sensitivity
By changing the settings on the menu of the Uconnect
system, you can change the sensitivity of the system by
choosing one of the following three options: Near,Me-
dium orFar. Refer to “Uconnect Settings” in “Multime-
dia” for further information.
The default option is Medium. This setting provides that
the system notify the driver of a possible accident with the
vehicle ahead of it when the latter is at a standard distance,
intermediate between the other two possible settings.
By setting the sensitivity of the system to Far, the system
will warn the driver of a possible accident with the vehicle
in front when the latter is at a greater distance, giving you the chance to act on the brakes in a more limited and
gradual. This setting gives the driver the maximum pos-
sible time of reaction to prevent a possible accident.
By changing the option to
Near, the system will warn the
driver of a possible accident with the vehicle ahead of it
when the latter is a reduced distance. This setting offers a
reaction time to the driver lower than the settings Me-
dium andFar, in the case of a potential accident, while a
more dynamic driving of the vehicle.
The setting of the sensitivity of the system is maintained in
memory when the engine is switched off.FCW Limited Warning
If the instrument cluster display reads “FCW Limited
Functionality” or “FCW Limited Functionality Wipe Front
Windshield” momentarily, there may be a condition that
limits FCW functionality. Although the vehicle is still
drivable 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 your authorized dealer.

Air Bag Warning Light
The ORC monitors the readiness of the electronic parts of
the air bag system whenever the ignition switch is in the
AVV/START or MAR/ACC/ON/RUN position. If the
ignition switch is in the STOP/OFF/LOCK position the air
bag system is not on and the air bags will not inflate.
The ORC contains a backup power supply system that may
deploy the air bag system even if the battery loses power or
it becomes disconnected prior to deployment.
The ORC turns on the Air Bag Warning Light in the
instrument panel for approximately four to eight seconds
for a self-check when the ignition switch is in the MAR/
ACC/ON/RUN position. After the self-check, the Air Bag
Warning Light will turn off. If the ORC detects a malfunc-
tion in any part of the system, it turns on the Air Bag
Warning Light, either momentarily or continuously. A
single chime will sound to alert you if the light comes on
again after initial startup.
The ORC also includes diagnostics that will illuminate the
instrument panel Air Bag Warning Light if a malfunction is
detected that could affect the air bag system. The diagnos-
tics also record the nature of the malfunction. While the airbag system is designed to be maintenance free, if any of the
following occurs, have an authorized dealer service the air
bag system immediately.
•
The Air Bag Warning Light does not come on during the
four to eight seconds when the ignition switch is first in
the MAR/ACC/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.
WARNING!
Ignoring the Air Bag Warning Light in your instrument
panel could mean you won’t have the air bag system to
protect you in a collision. If the light does not come on
as a bulb check when the ignition is first turned on,

see your doctor. If these particles settle on your clothing,
follow the garment manufacturer ’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 pretensioners cannot
protect you in another collision. Have the air bags, seat
belt pretensioners, and the seat belt retractor assem-
blies replaced by an authorized dealer immediately.
Also, have the Occupant 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 communication 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 System 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 deactivated 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 Enhanced Accident Response Sys-
tem.
• Unlock the power door locks.
• Turn off the Fuel Pump Heater — If Equipped.
• Turn off the HVAC Blower Motor.
• Close the HVAC Circulation Door.
