184STARTING AND OPERATING
Tongue Weight (TW)
The tongue weight 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
multiplied by the maximum width of the front of
a trailer.
Trailer Sway Control
The Trailer Sway Control 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 Trailer Sway Control
(TSC) recognizes a swaying trailer and automat -
ically 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 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 recommended 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
standard 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!
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.

Trailer Towing Weights (Maximum Trailer Weight Ratings)
The following chart provides the maximum trailer weight ratings towable for your given drivetrain:
NOTE:
The trailer tongue weight must be considered as
part of the combined weight of occupants and
cargo, and should never exceed the weight
referenced on the Tire and Loading Information
placard. Refer to “Tire Safety Information” in
“Servicing and Maintenance” for further
information.
Trailer And Tongue Weight
Never exceed the maximum tongue weight
stamped on your bumper or trailer hitch.

3,000 lbs (1 360 kg)* 300 lbs (136 kg)
*Refer to local laws for maximum trailer towing speeds.
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.

STARTING AND OPERATING187
(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
“Scheduled 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.
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.

190STARTING AND OPERATING
Automatic Transmission
The DRIVE range can be selected when towing.
However, if frequent shifting occurs while in
DRIVE, use the Electronic Range Select (ERS)
shift control to manually 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
buildup. This action will also provide better
engine braking.
If you REGULARLY tow a trailer for more than
45 minutes of continuous operation, then
change the transmission fluid and filter as
specified for "police, taxi, fleet, or frequent
trailer towing." Refer to the “Maintenance Plan”
for the proper maintenance intervals. Electronic Range Select (ERS)When using the ERS shift control, select the
highest gear that allows for adequate perfor
-
mance and avoids frequent downshifts. For
example, choose “4” if the desired speed can
be maintained. Choose “3” or “2” if needed
to maintain 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 conditions allow.
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 Warnings and Cautions 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.
