246 SAFETY
The air bag system must be ready to protect you in a colli-
sion. The Occupant Restraint Controller (ORC) monitors the
internal circuits and interconnecting wiring associated with
the electrical Air Bag System Components. Your vehicle may
be equipped with the following Air Bag System Compo -
nents:
Air Bag System Components
• Occupant Restraint Controller (ORC)
• Air Bag Warning Light
• Steering Wheel and Column
• Instrument Panel
• Knee Impact Bolsters
• Driver and Front Passenger Air Bags
• Seat Belt Buckle Switch
• Supplemental Side Air Bags
• Front and Side Impact Sensors
• Seat Belt Pretensioners
• Seat Track Position Sensors
• Occupant Classification System 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 START or ON/RUN position. If the
ignition switch is in the OFF position or in the ACC 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 instru-
ment panel for approximately four to eight seconds for a
self-check when the ignition switch is first in the ON/RUN
position. After the self-check, the Air Bag Warning Light will
turn off. If the ORC detects a malfunction 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 diagnostics
also record the nature of the malfunction. While the air bag

switch to avoid draining the battery. Carefully check the
vehicle for fuel leaks in the engine compartment and on the
ground near the engine compartment and fuel 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. If you have any doubt,
contact an authorized dealer.
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 compartment and fuel
tank before resetting the system and starting the engine.
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. 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 passenger side of the instru -
ment panel. Do not modify the front bumper, vehicle
body structure, or add aftermarket side steps or

POWER STEERING
Electric Power Steering
The electric power steering system will give you effective
vehicle response and increased ease of maneuverability in
tight spaces. The system will vary its assist to provide light
efforts while parking and proper feel while driving. If the
electric steering system experiences a fault that prevents it
from providing assist, you will still have the ability to steer
the vehicle manually.
If the Steering icon is flashing, it indicates that the vehicle
needs to be taken to the dealer for service. It is likely the
vehicle has lost power steering assistance.
If the Steering icon is displayed and the “POWER STEERING
SYSTEM OVER TEMP” message is displayed on the instru-
ment cluster screen, they indicate that extreme steering
maneuvers may have occurred which caused an over
temperature condition in the power steering system. Once
driving conditions are safe, pull over and let the vehicle idle
for a few moments until the icon and message turn off. Refer
to “Instrument Cluster Display” in “Getting To Know Your
Instrument Panel” for further information.
If the Steering icon is displayed and the “SERVICE POWER
STEERING – ASSIST OFF” message is displayed the instru-ment cluster screen, they indicate the vehicle needs to be
taken to the dealer for service. Refer to “Instrument Cluster
Display” in “Getting To Know Your Instrument Panel” for
further information.
NOTE:
• Even if the power steering assistance is no longer opera
-
tional, it is still possible to steer the vehicle. Under these
conditions there will be a substantial increase in steering
effort, especially at low speeds and during parking
maneuvers.
• If the condition persists, see your authorized dealer for service.
FUEL SAVER TECHNOLOGY 5.7L ENGINES ONLY —
IF EQUIPPED
This feature offers improved fuel economy by shutting off
four of the engine's eight cylinders during light load and
cruise conditions. The system is automatic with no driver
inputs or additional driving skills required.
NOTE:
This system may take some time to return to full function -
ality after a battery disconnect.

STARTING AND OPERATING 409

If equipped, the electronic TSC recognizes a swaying trailer
and automatically applies individual wheel brakes and/or
reduces engine power to attempt to eliminate the trailer sway.

Weight-Carrying Hitch
A weight-carrying hitch supports the trailer tongue weight,
just as if it were luggage located at a hitch ball or some other
connecting point of the vehicle. These kinds of hitches are the
most popular on the market today and they are commonly
used to tow small and medium sized trailers.
Weight-Distributing Hitch
A weight-distributing system works by applying leverage
through spring (load) bars. They are typically used for
heavier loads to distribute trailer tongue weight to the tow
vehicle's front axle and the trailer axle(s). When used in
accordance with the manufacturer's directions, it provides
for a more level ride, offering more consistent steering and
brake control, thereby enhancing towing safety. The addi-
tion of a friction/hydraulic sway control also dampens sway
caused by traffic and crosswinds and contributes positively
to tow vehicle and trailer stability. Trailer sway control and
a weight distributing (load equalizing) hitch are recom -
mended for heavier Tongue Weights (TW) and may be
required depending on vehicle and trailer configuration/
loading to comply with GAWR requirements. Without Weight-Distributing Hitch (Incorrect)WARNING!
• An improperly adjusted weight distributing hitch system may reduce handling, stability and braking
performance and could result in a collision.
• Weight distributing systems may not be compatible with surge brake couplers. Consult with your hitch and
trailer manufacturer or a reputable Recreational
Vehicle dealer for additional information.

GAIN Adjustment Buttons (+/-)
Pushing these buttons will adjust the brake control power
output to the trailer brakes in 0.5 increments. The GAIN
setting can be increased to a maximum of 10 or decreased to
a minimum of 0 (no trailer braking).
GAIN
The GAIN setting is used to set the trailer brake control for
the specific towing condition and should be changed as
towing conditions change. Changes to towing conditions
include trailer load, vehicle load, road conditions and
weather.
Adjusting GAIN
NOTE:
This should only be performed in a traffic free environment
at speeds of approximately 20–25 mph (30–40 km/h).
1. Make sure the trailer brakes are in good working condi-
tion, functioning normally and properly adjusted. See
your trailer dealer if necessary.
2. Hook up the trailer and make the electrical connections according to the trailer manufacturer's instructions.
3. When a trailer with electric/EOH brakes is plugged in, the trailer connected message should appear in the
instrument cluster display (if the connection is not recog -nized by the ITBM, braking functions will not be avail
-
able), the GAIN setting will illuminate and the correct
type of trailer must be selected from the instrument
cluster display options.
4. Push the UP or DOWN button on the steering wheel until “TRAILER TOW” appears on the screen.
5. Push the RIGHT arrow on the steering wheel to enter “TRAILER TOW”.
6. Push the UP or DOWN buttons until the Trailer Brake Type appears on the screen.
7. Push the RIGHT arrow and then push the UP or DOWN buttons until the proper Trailer Brake Type appears on
the screen.
8. In a traffic-free environment, tow the trailer on a dry, level surface at a speed of 20–25 mph (30–40 km/h) and
squeeze the manual brake control lever completely.
9. If the trailer wheels lockup (indicated by squealing tires), reduce the GAIN setting; if the trailer wheels turn freely,
increase the GAIN setting.
Repeat steps 8 and 9 until the GAIN setting is at a point just
below trailer wheel lockup. If towing a heavier trailer, trailer
wheel lockup may not be attainable even with the maximum
GAIN setting of 10.
