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.

REFUELING THE VEHICLE
The gas cap is located behind the fuel filler door on the left
side of the vehicle. If the gas cap is lost or damaged, be sure
the replacement cap is for use with this vehicle.
1. Open the fuel filler door.
2. Remove the fuel cap by rotating it counterclockwise.Fuel Filler Cap NOTE:
The driver's side sliding door cannot be opened while the
fuel door is open. This feature operates only when the sliding
door is in a closed position prior to opening the fuel door.
3. Fully insert the gasoline nozzle into the filler pipe.
4. Fill the vehicle with fuel.
NOTE:
When the fuel nozzle “clicks” or shuts off, the fuel tank is
full.
5. Remove gasoline nozzle, reinstall fuel cap and close fuel
filler door.
WARNING!
• Never have any smoking materials lit in or near the vehicle when the gas cap is removed or the tank is
being filled.
• Never add fuel when the engine is running. This is in violation of most state and federal fire regulations and
may cause the “Malfunction Indicator Light (MIL)”to
turn on.

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.

STARTING AND OPERATING 189
Consider the following items when computing the weight on
the rear axle of the vehicle:
• The tongue weight of the trailer.
• The weight of any other type of cargo or equipment put inor on your vehicle.
• The weight of the driver and all passengers.
NOTE:
Remember that everything put into or on the trailer adds to
the load on your vehicle. Also, additional factory-installed
options or dealer-installed options must be considered as
part of the total load on your vehicle. Refer to the “Tire And
Loading Information” placard for the maximum combined
weight of occupants and cargo for your vehicle.
Towing Requirements
To promote proper break-in of your new vehicle drivetrain
components, the following guidelines are recommended.
Perform the maintenance listed in “Scheduled Servicing”.
Refer to “Scheduled Servicing” in “Servicing And Mainte -
nance” for the proper maintenance intervals. When towing a
trailer, never exceed the GAWR or GCWR ratings.
CAUTION!
Always load a trailer with 60% of the weight in the front
of the trailer. This places 10% of the GTW on the tow
hitch of your vehicle. Loads balanced over the wheels or
heavier in the rear can cause the trailer to sway severely
side to side which will cause loss of control of the vehicle
and trailer. Failure to load trailers heavier in front is the
cause of many trailer collisions.
CAUTION!
• Do not tow a trailer at all during the first 500 miles (805 km) the new vehicle is driven. The engine, axle or
other parts could be damaged.
• Then, during the first 500 miles (805 km) that a trailer is towed, do not drive over 50 mph (80 km/h) and do not
make starts at full throttle. This helps the engine and
other parts of the vehicle wear in at the heavier loads.

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.

Towing Tips
Before setting out on a trip, practice turning, stopping, and
backing up the trailer in an area located away from heavy
traffic.
Automatic Transmission
The DRIVE range can be selected when towing. The trans-
mission controls include a drive strategy to avoid frequent
shifting when towing. However, if frequent shifting does
occur while in DRIVE, use the Electronic Range Select (ERS)
shift control to select a lower gear range.
NOTE:
Using a lower gear range while operating the vehicle under
heavy loading conditions will improve performance and
extend transmission life by reducing excessive shifting and
heat build up. This action will also provide better engine
braking.

194 STARTING AND OPERATING
Electronic Range Select (ERS)
• When using the ERS shift control, select the highest gearthat allows for adequate performance and avoids frequent
downshifts. For example, choose “5” if the desired speed
can be maintained. Choose “4” or “3” if needed to main -
tain the desired speed.
• To prevent excess heat generation, avoid continuous driving at high RPM. Reduce vehicle speed as necessary to
avoid extended driving at high RPM. Return to a higher
gear range or vehicle speed when grade and road condi -
tions allow.
Speed Control — If Equipped
• Do not use on hilly terrain or with heavy loads.
• When using the Speed Control, if you experience speed drops greater than 10 mph (16 km/h), disengage until you
can get back to cruising speed.
• Use Speed Control in flat terrain and with light loads to maximize fuel efficiency. Cooling System
To reduce potential for engine and transmission over
-
heating, take the following actions:
City Driving
• In city traffic — while stopped, place the transmission in NEUTRAL, but do not increase engine idle speed.
Highway Driving
• Reduce speed.
• Temporarily turn off air conditioning.

CAUTION!
• Always check the depth of the standing water before driving through it. Never drive through standing water
that is deeper than the bottom of the tire rims mounted
on the vehicle.
• Determine the condition of the road or the path that is under water and if there are any obstacles in the way
before driving through the standing water.
• Do not exceed 5 mph (8 km/h) when driving through standing water. This will minimize wave effects.
• Driving through standing water may cause damage toyour vehicle’s drivetrain components. Always inspect
your vehicle’s fluids (i.e., engine oil, transmission, axle,
etc.) for signs of contamination (i.e., fluid that is milky
or foamy in appearance) after driving through standing
water. Do not continue to operate the vehicle if any
fluid appears contaminated, as this may result in
further damage. Such damage is not covered by the
New Vehicle Limited Warranty.
• Getting water inside your vehicle’s engine can cause it to lock up and stall out, and cause serious internal
damage to the engine. Such damage is not covered by
the New Vehicle Limited Warranty. CAUTION!

212 IN CASE OF EMERGENCY
JACKING AND TIRE CHANGING Jack Location — If Equipped
The jack and tools are stowed under the rear drivers front
seat or in the rear cargo area. It depends on the trim level.
Jack/Tools LocationWARNING!
• Do not attempt to change a tire on the side of the vehicle close to moving traffic. Pull far enough off the road to
avoid the danger of being hit when operating the jack
or changing the wheel.
• Being under a jacked-up vehicle is dangerous. The vehicle could slip off the jack and fall on you. You
could be crushed. Never put any part of your body
under a vehicle that is on a jack. If you need to get
under a raised vehicle, take it to a service center where
it can be raised on a lift.
• Never start or run the engine while the vehicle is on a jack.
• The jack is designed to be used as a tool for changing tires only. The jack should not be used to lift the
vehicle for service purposes. The vehicle should be
jacked on a firm level surface only. Avoid ice or slip -
pery areas.
