SAFETY 131
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 (if equipped)
• Cut off battery power to the electric motor (if equipped)
• Flash hazard lights as long as the battery has power
• Turn on the interior lights, which remain on as long as thebattery has power or for 15 minutes from the intervention
of the Enhanced Accident Response System
• Unlock the power door locks

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
running boards.
• It is dangerous to try to repair any part of the air bag system yourself. Be sure to tell anyone who works on
your vehicle that it has an air bag system.
• Do not attempt to modify any part of your air bag system. The air bag may inflate accidentally or may not
function properly if modifications are made. Take your
vehicle to an authorized dealer for any air bag system
service. If your seat, including your trim cover and
cushion, needs to be serviced in any way (including
removal or loosening/tightening of seat attachment
bolts), take the vehicle to an authorized dealer. Only
manufacturer approved seat accessories may be used. If
it is necessary to modify the air bag system for persons
with disabilities, contact an authorized dealer.

STARTING AND OPERATING 171
POWER STEERING
The standard power steering system will give you good
vehicle response and increased ease of maneuverability in
tight spaces. The system will provide mechanical steering
capability if power assist is lost.

If for some reason the power assist is interrupted, it will still be
possible to steer your vehicle. Under these conditions, you will
observe a substantial increase in steering effort, especially at
very low vehicle speeds and during parking maneuvers.

NOTE:
• Increased noise levels at the end of the steering wheeltravel are considered normal and do not indicate that there
is a problem with the power steering system.
• Upon initial start-up in cold weather, the power steering pump may make noise for a short amount of time. This is
due to the cold, thick fluid in the steering system. This
noise should be considered normal, and it does not in any
way damage the steering system.
Power Steering Fluid Check
Checking the power steering fluid level at a defined service
interval is not required. The fluid should only be checked if
a leak is suspected, abnormal noises are apparent, and/or
the system is not functioning as anticipated. Coordinate
inspection efforts through your authorized dealer. CAUTION!
Prolonged operation of the steering system at the end of
the steering wheel travel will increase the steering fluid
temperature and it should be avoided when possible.
Damage to the power steering pump may occur.
WARNING!
Fluid level should be checked on a level surface and with
the engine off to prevent injury from moving parts and
to ensure accurate fluid level reading. Do not overfill.
Use only manufacturer's recommended power steering
fluid.

172 STARTING AND OPERATING
If necessary, add fluid to restore to the proper indicated
level. With a clean cloth, wipe any spilled fluid from all
surfaces. Refer to “Fluids And Lubricants” in “Technical
Specifications” for further information.
SPEED CONTROL — IF EQUIPPED
When engaged, the Speed Control takes over accelerator
operations at speeds greater than 25 mph (40 km/h).
The Speed Control buttons are located on the right side of the
steering wheel.Speed Control Buttons
To Activate
Push the on/off button to activate the Speed Control. The
cruise indicator light in the instrument cluster display will
illuminate. To turn the system off, push the on/off button a
second time. The cruise indicator light will turn off. The
system should be turned off when not in use.
CAUTION!
Do not use chemical flushes in your power steering
system as the chemicals can damage your power steering
components. Such damage is not covered by the New
Vehicle Limited Warranty.

186 STARTING AND OPERATING
If equipped, the electronic Trailer Sway Control (TSC) recog-
nizes 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
The weight-distributing hitch 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 addition
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 Gross Axle Weight Rating (GAWR)
requirements.
WARNING!
• An improperly adjusted Weight Distributing Hitch system may reduce handling, stability, braking perfor -
mance, 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.

190 STARTING AND OPERATING
(Continued)
WARNING!
• Make certain that the load is secured in the trailer and will not shift during travel. When trailering cargo that
is not fully secured, dynamic load shifts can occur that
may be difficult for the driver to control. You could lose
control of your vehicle and have a collision.
• When hauling cargo or towing a trailer, do not overload your vehicle or trailer. Overloading can cause a loss of
control, poor performance or damage to brakes, axle,
engine, transmission, steering, suspension, chassis
structure or tires.
• Safety chains must always be used between your vehicle and trailer. Always connect the chains to the
hook retainers of the vehicle hitch. Cross the chains
under the trailer tongue and allow enough slack for
turning corners.
• Vehicles with trailers should not be parked on a grade.When parking, apply the parking brake on the tow
vehicle. Put the tow vehicle transmission in PARK. For
four-wheel drive vehicles, make sure the transfer case
is not in NEUTRAL. Always, block or "chock" the
trailer wheels.
• GCWR must not be exceeded.
• Total weight must be distributed between the tow vehicle and the trailer such that the following four
ratings are not exceeded:
• GVWR
• GTW
• GAWR
• Tongue weight rating for the trailer hitch utilized.
