the specified GVWR, you must redistribute the weight.
Improper weight distribution can have an adverse effect on
the way your vehicle steers and handles and the way the
brakes operate.
NOTE:Refer to the “Vehicle Certification Label” affixed to
the rear of the driver’s door for your vehicle’s GVWR and
GAWRs.
TRAILER TOWING
In this section you will find safety tips and information on
limits to the type of towing you can reasonably do with your
vehicle. Before towing a trailer, carefully review this infor-
mation to tow your load as efficiently and safely as possible.
To maintain the New Vehicle Limited Warranty coverage,
follow the requirements and recommendations in this
manual concerning vehicles used for trailer towing.
Common Towing Definitions
The following trailer towing related definitions will assist
you in understanding the following information:
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your vehicle.
This includes driver, passengers, cargo and tongue weight. The total load must be limited so that you do not exceed
the GVWR. Refer to “Vehicle Loading/Vehicle Certification
Label” in “Starting And Operating” for further informa-
tion.
Gross Combination Weight Rating (GCWR)
The GCWR is the total allowable weight of your vehicle
and trailer when weighed in combination.
Gross Trailer Weight (GTW)
The GTW is the weight of the trailer plus the weight of all
cargo, consumables and equipment (permanent or tempo-
rary) loaded in or on the trailer in its
loaded and ready for
operation condition.
The recommended way to measure GTW is to put your
fully loaded trailer on a vehicle scale. The entire weight of
the trailer must be supported by the scale.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity of the front and rear
axles. Distribute the load over the front and rear axles evenly.
Make sure that you do not exceed either front or rear GAWR.
Refer to “Vehicle Loading/Vehicle Certification Label” in
“Starting And Operating” for further information.
182 STARTING AND OPERATING

CAUTION!
If the trailer weighs more than 1,000 lbs (453 kg)
loaded, it should have its own brakes and they should
be of adequate capacity. Failure to do this could lead to
accelerated brake lining wear, higher brake pedal
effort, and longer stopping distances.
Towing Requirements — Trailer Lights And Wiring
Whenever you pull a trailer, regardless of the trailer size,
stoplights and turn signals on the trailer are required for
motoring safety.
The Trailer Tow Package may include a four- and seven-pin
wiring harness. Use a factory approved trailer harness and
connector.
NOTE:Do not cut or splice wiring into the vehicle’s wiring
harness.
The electrical connections are all complete to the vehicle
but you must mate the harness to a trailer connector. Refer
to the following illustrations. NOTE:
•
Disconnect trailer wiring connector from the vehicle
before launching a boat (or any other device plugged
into vehicle’s electrical connect) into water.
• Be sure to reconnect after clear from water area.

Tire And Loading Information Placard
This placard tells you important information about the:
1. Number of people that can be carried in the vehicle.
2. Total weight your vehicle can carry.
3. Tire size designed for your vehicle.
4. Cold tire inflation pressures for the front, rear, and sparetires.Loading
The vehicle maximum load on the tire must not exceed the
load carrying capacity of the tire on your vehicle. You will
not exceed the tire’s load carrying capacity if you adhere to
the loading conditions, tire size, and cold tire inflation
pressures specified on the Tire and Loading Information
placard in “Vehicle Loading” in the “Starting And Operat-
ing” section of this manual.
NOTE: Under a maximum loaded vehicle condition, gross
axle weight ratings (GAWRs) for the front and rear axles
must not be exceeded.
For further information on GAWRs, vehicle loading, and
trailer towing, refer to “Vehicle Loading” in the “Starting
And Operating” section of this manual.
To determine the maximum loading conditions of your
vehicle, locate the statement “The combined weight of
occupants and cargo should never exceed XXX kg or
XXX lbs” on the Tire and Loading Information placard. The
combined weight of occupants, cargo/luggage and trailer
tongue weight (if applicable) should never exceed the
weight referenced here.

Steps For Determining Correct Load Limit—
(1) Locate the statement “The combined weight of
occupants and cargo should never exceed XXX kg or
XXX lbs.” on your vehicle’s placard.
(2) Determine the combined weight of the driver and
passengers that will be riding in your vehicle.
(3) Subtract the combined weight of the driver and
passengers from XXX kg or XXX lbs.
(4) The resulting figure equals the available amount of
cargo and luggage load capacity. For example, if “XXX”
amount equals 1400 lbs. and there will be five 150 lb
passengers in your vehicle, the amount of available
cargo and luggage load capacity is 650 lbs. (1400-750
(5x150) = 650 lbs.)
(5) Determine the combined weight of luggage and
cargo being loaded on the vehicle. That weight may not
safely exceed the available cargo and luggage load
capacity calculated in Step 4.
(6) If your vehicle will be towing a trailer, load from
your trailer will be transferred to your vehicle. Consult
this manual to determine how this reduces the available
cargo and luggage load capacity of your vehicle.Metric Example For Load Limit
For example, if “XXX” amount equals 635 kg and there will
be five 68 kg passengers in your vehicle, the amount of
available cargo and luggage load capacity is 295 kg (635-
340 (5x68) = 295 kg) as shown in step 4.
NOTE:
•If your vehicle will be towing a trailer, load from your
trailer will be transferred to your vehicle. The following
table shows examples on how to calculate total load,
cargo/luggage, and towing capacities of your vehicle
with varying seating configurations and number and
size of occupants. This table is for illustration purposes
only and may not be accurate for the seating and load
carry capacity of your vehicle.
