Power Steering Fluid Check
Checking the power steering fluid level at a
defined service interval is not required. The fluid
should be checked at every oil change if a leak
is suspected, abnormal noises are apparent,
and/or the system is not functioning as antici -
pated. Coordinate inspection efforts through an
authorized dealer. 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) up to the maximum speed of
100 mph (160 km/h).
The Speed Control lever is located on the left
side of the steering column.
Speed Control Lever NOTE:
In order to ensure proper operation, the Speed
Control system has been designed to shut down

center ring upward a second time. The Cruise
Indicator Light will turn off. The system should
be turned off when not in use.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.
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.
WARNING!
Leaving the Speed Control system on when
not in use is dangerous. You could
accidentally set the system or cause it to go

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.
Fuel Filler
NOTE:
During fuel fill, nozzle position could affect the
flow of fuel. For best results, allow the nozzle to
rest naturally in the filler tube - do not raise the
handle to increase the fill angle. NOTE:When the fuel nozzle “clicks” or shuts off, the
fuel tank is full.
Tighten the fuel filler cap until you hear a
“clicking” sound. This is an indication that the
fuel filler cap is properly tightened.
If the gas cap is not tightened properly, the
MIL may come on. Be sure the gas cap is
tightened every time the vehicle is refueled.
Loose Fuel Filler Cap Message
If the vehicle diagnostic system determines that
the fuel filler cap is loose, improperly installed,
or damaged, a “Check fuel cap” message will be
displayed in the instrument cluster display.
Refer to “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel” for
further information. Tighten the fuel filler cap
until a “clicking” sound is heard. This is an indi
-
cation that the fuel filler cap is properly tight -
ened. Refer to “Onboard Diagnostic System” in
“Getting To Know Your Instrument Panel” for
further information.
If the problem continues, the message will
appear the next time the vehicle is started. See
your authorized dealer as soon as possible.
WARNING!
Never have any smoking materials lit in or
near the vehicle when the fuel door is open
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” to turn on.
A fire may result if fuel is pumped into a
portable container that is inside of a
vehicle. You could be burned. Always place
fuel containers on the ground while filling.
CAUTION!
Damage to the fuel system or emissions
control system could result from using an
improper fuel tank filler tube cap.
A poorly fitting fuel filler cap could let impu -
rities into the fuel system.
A poorly fitting fuel filler cap may cause the
“Malfunction Indicator Light (MIL)” to turn
on.
To avoid fuel spillage and overfilling, do not
“top off” the fuel tank after filling. When the
fuel nozzle “clicks” or shuts off, the fuel
tank is full.

114STARTING AND OPERATING
Tongue Weight (TW)
The Tongue Weight (TW) is the downward force
exerted on the hitch ball by the trailer. You must
consider this as part of the load on your vehicle.
Trailer Frontal Area
The frontal area is the maximum height multi -
plied by the maximum width of the front of a
trailer.
Trailer Sway Control
The Trailer Sway Control (TSC) can be a
mechanical telescoping link that can be
installed between the hitch receiver and the
trailer tongue that typically provides adjustable
friction associated with the telescoping motion
to dampen any unwanted trailer swaying
motions while traveling. If equipped, the electronic TSC recognizes a
swaying trailer and automatically applies indi
-
vidual 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 accor -
dance 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 fric -
tion/hydraulic sway control also dampens sway
caused by traffic and crosswinds and contrib -
utes 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.
Trailer Hitch Classification
The following chart provides the industry stan -
dard for the maximum trailer weight a given
trailer hitch class can tow and should be used to
assist you in selecting the correct trailer hitch
for your intended towing condition.
WARNING!
It is important that you do not exceed the
maximum front or rear GAWR. A dangerous
driving condition can result if either rating is
exceeded. You could lose control of the
vehicle and have a collision.
WARNING!
An improperly adjusted Weight Distributing
Hitch system may reduce handling,
stability, 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 manufac -
turer or a reputable Recreational Vehicle
dealer for additional information.

(Continued)
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 in or 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 the “Sched
-
uled Servicing”. Refer to “Scheduled Servicing”
in “Servicing And Maintenance” for the proper
maintenance intervals. When towing a trailer,
never exceed the GAWR or GCWR ratings.
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. Over -
loading can cause a loss of control, poor
performance or damage to brakes, axle,
engine, transmission, steering, suspension,
chassis structure or tires.

CAUTION!
(Continued)

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.

Automatic Transmission
The DRIVE range can be selected when towing.
The transmission controls include a drive
strategy to avoid frequent shifting when towing.
However, if frequent shifting does occur while in
DRIVE, select TOW/HAUL mode or select a lower
gear range (using the Electronic Range Select
(ERS) shift control).
NOTE:
Using TOW/HAUL mode or selecting a lower
gear range (using the ERS shift control) 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.
When towing a loaded trailer up steep grades at
low speeds, holding your vehicle in first gear
(using the ERS shift control) can help to avoid
transmission overheating.
Tow/Haul Mode
To reduce potential for automatic transmission
overheating, activate TOW/HAUL mode when
driving in hilly areas, or select a lower gear
range (using the Electronic Range Select (ERS)
shift control) on more severe grades.
Speed Control — If Equipped
Do not use on hilly terrain or with heavy
loads.
When using the speed control, if you experi -
ence 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
overheating, take the following actions:
City Driving
In city traffic — while stopped, place the trans -
mission in NEUTRAL, but do not increase engine
idle speed.
Highway Driving
Reduce speed.
Temporarily turn off air conditioning.

Shallow Standing Water
Although your vehicle is capable of driving
through shallow standing water, consider the
following Cautions and Warnings before doing
so.
WARNING!
Driving through standing water limits your
vehicle’s traction capabilities. Do not
exceed 5 mph (8 km/h) when driving
through standing water.
Driving through standing water limits your
vehicle’s braking capabilities, which
increases stopping distances. Therefore,
after driving through standing water, drive
slowly and lightly press on the brake pedal
several times to dry the brakes.
Failure to follow these warnings may result
in injuries that are serious or fatal to you,
your passengers, and others around you.
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 to your vehicle’s drivetrain compo -
nents. 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.
