2005 MAZDA MODEL B2300 TRUCK Owners Manual (in English)

GVW (Gross Vehicle Weight)–is the Vehicle Curb Weight + cargo +
passengers.
GVWR (Gross Vehicle Weight
Rating)–is the maximum
allowable weight of the fully loaded
vehicle (including all options,
equipment, passengers and cargo).
The GVWR is shown on the
Safety Compliance Certification
Label located on the driver’s
door or B-Pillar. The GVW must
never exceed the GVWR.
WARNING: Exceeding the Safety Certification Label vehicle
weight rating limits could result in substandard vehicle handling
or performance, engine, transmission and/or structural damage,
serious damage to the vehicle, loss of control and personal
injury.

GCW (Gross Combined Weight)–is the weight of the loaded vehicle
(GVW) plus the weight of the fully loaded trailer.
GCWR (Gross Combined Weight Rating)–is the maximum allowable
weight of the vehicle and the loaded trailer–including all cargo and
passengers–that the vehicle can handle without risking damage.
(Important: The towing vehicle’s braking system is rated for operation at
GVWR, not at GCWR. Separate functional brakes should be used for safe
control of towed vehicles and for trailers where the GCW of the towing
vehicle plus the trailer exceed the GVWR of the towing vehicle.The
GCW must never exceed the GCWR.
Maximum Loaded Trailer Weight–is the highest possible weight of a
fully loaded trailer the vehicle can tow. It assumes a vehicle with only
mandatory options, no cargo (internal or external), a tongue load of
10–15% (conventional trailer) or king pin weight of 15–25% (fifth wheel
trailer), and driver only (150 lb. [68 kg]).Consult your dealership (or
theRV and Trailer Towing Guideprovided by your dealership) for
more detailed information.
Tongue Load or Fifth Wheel King Pin Weight–refers to the amount
of the weight that a trailer pushes down on a trailer hitch.
Examples:For a 5,000 lb. (2,268 kg) conventional trailer, multiply 5,000
by 0.10 and 0.15 to obtain a proper tongue load range of 500 to 750 lb.
(227 to 340 kg). For an 11,500 lb. (5,216 kg) fifth wheel trailer, multiply
by 0.15 and 0.25 to obtain a proper king pin load range of 1,725 to 2,875
lb. (782 to 1,304 kg)
WARNING: Do not exceed the GVWR or the GAWR specified on
the certification label.
WARNING: Do not use replacement tires with lower load
carrying capacities than the originals because they may lower
the vehicle’s GVWR and GAWR limitations. Replacement tires
with a higher limit than the originals do not increase the GVWR
and GAWR limitations.

WARNING: Exceeding any vehicle weight rating limitation
could result in serious damage to the vehicle and/or personal
injury.
Steps for determining the correct load limit:
1. Locate the statement“The combined weight of occupants and cargo
should never exceed XXX pounds”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 kilograms or XXX pounds.
4. The resulting figure equals the available amount of cargo and
luggage load capacity. For example, if the“XXX”amount equals
1,400 lb. and there will be five 150 lb. passengers in your vehicle, the
amount of available cargo and luggage load capacity is 650 lb.
(1400–750 (5 x 150) = 650 lb.).
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.
The following gives you a few more examples on how to calculate the
available amount of cargo and luggage load capacity:
•Another example for your vehicle with 1400 pounds of cargo and
luggage capacity. You decide to go golfing. You and your friends
average 220 pounds each and the golf bags weigh approximately 30
pounds each. Is there enough load capacity to carry you, 4 of your
friends and all the golf bags? The calculation would be: 1400–(5 x
220)–(5 x 30) = 1400–1100–150 = 150 pounds; yes, you have
enough load capacity in your vehicle to transport 4 of your friends and
golf bags.
•A final example for your vehicle with 1400 pounds of cargo and
luggage capacity. You and one of your friends decide to pick up
cement from the local home improvement store to finish that patio
you have been planning for the past 2 years. Measuring the inside of
the vehicle with the rear seat folded down, you have room for 12-100

pound bags of cement. Do you have enough load capacity to transport
the cement to your home? If you and your friend each weighed 220
pounds, the calculation would be: 1400–(2 x 220)–(12 x 100) =
1400–440–1200 =–40 pounds; no, you do not have enough cargo
capacity to carry that much weight. You will need to reduce the load
weight by at least 240 pounds. If you remove 3-100 pound cement
bags, then the load calculation would be:
1400–(2 x 220)–(9 x 100) = 1400–440–900 = 60 pounds; now you
have the load capacity to transport the cement and your friend home.
The above calculations also assume that the loads are positioned in your
vehicle in a manner that does not overload the Front or the Rear Gross
Axle Weight Rating specified for your vehicle on the Certification label
found on the driver’s door.
Special loading instructions for owners of pickup trucks and
utility-type vehicles
WARNING: For important information regarding safe operation
of this type of vehicle, see the Preparing to drive your vehicle
section in this chapter.
WARNING: Loaded vehicles may handle differently than
unloaded vehicles. Extra precautions, such as slower speeds and
increased stopping distance, should be taken when driving a
heavily loaded vehicle.
Your vehicle can haul more cargo and people than most passenger cars.
Depending upon the type and placement of the load, hauling cargo and
people may raise the center of gravity of the vehicle.
TRAILER TOWING
Your vehicle may tow a class I, II or III trailer provided the maximum
trailer weight is less than or equal to the maximum trailer weight listed
for your engine and rear axle ratio on the following charts.
Your vehicle’s load capacity is designated by weight, not by volume, so
you cannot necessarily use all available space when loading a vehicle.
Towing a trailer places an additional load on your vehicle’s engine,
transmission, axle, brakes, tires and suspension. Inspect these
components carefully after any towing operation.
