Mazda B2300 Truck (2009 year). Instruction

Understanding your Tire Pressure Monitoring System (TPMS)

The Tire Pressure Monitoring System measures pressure in your four
road tires and sends the tire pressure readings to your vehicle. The Low
Tire Pressure Warning Lamp will turn ON if the tire pressure is
significantly low. Once the light is illuminated, your tires are under
inflated and need to be inflated to the manufacturer’s recommended tire
pressure. Even if the light turns ON and a short time later turns OFF,
your tire pressure still needs to be checked. Visit www.checkmytires.org
for additional information.

When your temporary spare tire is installed

When one of your road tires needs to be replaced with the temporary
spare, the TPMS system will continue to identify an issue to remind you
that the damaged road wheel/tire needs to be repaired and put back on
your vehicle.

To restore the full functionality of the Tire Pressure Monitoring System,
have the damaged road wheel/tire repaired and remounted on your
vehicle. For additional information, refer to Changing tires with TPMS
in this section.

When inflating your tires

When putting air into your tires (such as at a gas station or in your
garage), the Tire Pressure Monitoring System may not respond
immediately to the air added to your tires.

It may take up to two minutes of driving over 20 mph (32 km/h) for the
light to turn OFF after you have filled your tires to the recommended
inflation pressure.

How temperature affects your tire pressure

The Tire Pressure Monitoring System (TPMS) monitors tire pressure in
each pneumatic tire. While driving in a normal manner, a typical
passenger tire inflation pressure may increase approximately 2 to 4 psi
(14 to 28 kPa) from a cold start situation. If the vehicle is stationary
over night with the outside temperature significantly lower than the
daytime temperature, the tire pressure may decrease approximately 3 psi
(20.7 kPa) for a drop of 30° F (16.6°C) in ambient temperature. This
lower pressure value may be detected by the TPMS as being significantly
lower than the recommended inflation pressure and activate the TPMS
warning for low tire pressure. If the low tire pressure warning light is
ON, visually check each tire to verify that no tire is flat. (If one or more
tires are flat, repair as necessary.) Check air pressure in the road tires. If
any tire is under-inflated, carefully drive the vehicle to the nearest
location where air can be added to the tires. Inflate all the tires to the
recommended inflation pressure.

SNOW TIRES AND CHAINS

WARNING:

Driving too fast for conditions creates the possibility

of loss of vehicle control. Driving at very high speeds for

extended periods of time may result in damage to vehicle components.

WARNING:

Snow tires must be the same size, load index, speed

rating as those originally provided by Mazda. Use of any tire or

wheel not recommended by Mazda can affect the safety and
performance of your vehicle, which could result in an increased risk of
loss of vehicle control, vehicle rollover, personal injury and death.
Additionally, the use of non-recommended tires and wheels could
cause steering, suspension, axle or transfer case/power transfer unit
failure.

The tires on your vehicle have all weather treads to provide traction in
rain and snow. However, in some climates, you may need to use snow
tires and chains. If you need to use snow tires and chains, it is
recommended that steel wheels are used of the same size and
specifications as those originally installed.

Follow these guidelines when using snow tires and chains:
• Do not use tire chains on aluminum wheels. Chains may chip the

wheels.

• Use only SAE Class S chains.
• Install chains securely, verifying that the chains do not touch any

wiring, brake lines or fuel lines.

Drive cautiously. Ensure you obtain the proper cables or chains
for you vehicle. Test fit the cables or chains before using them in
snow and/or ice. If you hear the cables or chains rub or bang
against the vehicle, stop and retighten them. If this does not
work, remove the cables or chains to prevent vehicle damage.
Have the cables or chains fitted by a professional before
proceeding.
• If possible, avoid fully loading your vehicle.
• Remove the tire chains when they are no longer needed. Do not use

tire chains on dry roads.

• The suspension insulation and bumpers will help prevent vehicle

damage. Do not remove these components from your vehicle when
using snow tires and chains.

VEHICLE LOADING – WITH AND WITHOUT A TRAILER

This section will guide you in the proper loading of your vehicle and/or
trailer, to keep your loaded vehicle weight within its design rating
capability, with or without a trailer. Properly loading your vehicle will
provide maximum return of vehicle design performance. Before loading
your vehicle, familiarize yourself with the following terms for determining
your vehicle’s weight ratings, with or without a trailer, from the vehicle’s
Tire Label or Safety Compliance Certification Label:

Base Curb Weight

– is the weight of the vehicle including a full tank of

fuel and all standard equipment. It does not include passengers, cargo, or
optional equipment.

Vehicle Curb Weight

– is the weight of your new vehicle when you

picked it up from your authorized dealer plus any aftermarket
equipment.

Payload

– is the combined weight of cargo and passengers that the

vehicle is carrying. The maximum payload for your vehicle can be found
on the Tire Label on the B-Pillar or the edge of the driver’s door
(vehicles exported outside the US and Canada may not have a Tire
Label). Look for “THE COMBINED WEIGHT OF OCCUPANTS AND
CARGO SHOULD NEVER EXCEED XXX kg OR XXX lb.”

for

maximum payload. The payload listed on the Tire Label is the maximum
payload for the vehicle as built by the assembly plant. If any aftermarket
or authorized-dealer installed equipment has been installed on the
vehicle, the weight of the equipment must be subtracted from the
payload listed on the Tire Label in order to determine the new payload.

2009 B-Series (mbs)

Tires, Wheels and Loading

140

WARNING:

The appropriate loading capacity of your vehicle can

be limited either by volume capacity (how much space is

available) or by payload capacity (how much weight the vehicle should
carry). Once you have reached the maximum payload of your vehicle,
do not add more cargo, even if there is space available. Overloading or
improperly loading your vehicle can contribute to loss of vehicle
control and vehicle rollover.

Example only:

141

Cargo Weight

– includes all weight added to the Base Curb Weight,

including cargo and optional equipment. When towing, trailer tongue load
or king pin weight is also part of cargo weight.

GAW (Gross Axle Weight)

– is the total weight placed on each axle

(front and rear) – including vehicle curb weight and all payload.

GAWR (Gross Axle Weight Rating)

– is the maximum allowable

weight that can be carried by a single axle (front or rear). These
numbers are shown on the Safety Compliance Certification Label
located on the B-Pillar or the edge of the driver’s door. The total
load on each axle must never exceed its GAWR.

Note:

For trailer towing information refer to Trailer towing found in

this chapter or the RV and Trailer Towing Guide provided by your
authorized dealer.

GVW (Gross Vehicle Weight)

– is the Vehicle Curb Weight + cargo +

passengers.

2009 B-Series (mbs)
Owners Guide, 1st Printing
USA (fus)

Tires, Wheels and Loading

142

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 B-Pillar or
the edge of the driver’s door.
The GVW must never exceed the
GVWR.

WARNING:

Exceeding the Safety Compliance 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.

Tires, Wheels and Loading

143

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 authorized
dealer (or the RV and Trailer Towing Guide provided by your
authorized dealer) 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 Safety Compliance Certification Label.

WARNING:

Do not use replacement tires with lower load

carrying capacities than the original tires because they may

lower the vehicle’s GVWR and GAWR limitations. Replacement tires
with a higher limit than the original tires 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 kg or XXX lb.” 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 lb.

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.). In metric units (635-340 (5 x 68) =
295 kg.)

2009 B-Series (mbs)
Owners Guide, 1st Printing
USA (fus)

Tires, Wheels and Loading

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 examples on how to calculate the available
amount of cargo and luggage load capacity:
• Another example for your vehicle with 1,400 lb. (635 kg) of cargo and

luggage capacity. You decide to go golfing. Is there enough load
capacity to carry you, 4 of your friends and all the golf bags? You and
four friends average 220 lb. (99 kg) each and the golf bags weigh
approximately 30 lb. (13.5 kg) each. The calculation would be: 1400 -
(5 x 220) - (5 x 30) = 1400 - 1100 - 150 = 150 lb. Yes, you have
enough load capacity in your vehicle to transport four friends and
your golf bags. In metric units, the calculation would be: 635 kg - (5 x
99 kg) - (5 x 13.5 kg) = 635 - 495 - 67.5 = 72.5 kg.

• A final example for your vehicle with 1,400 lb. (635 kg) 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 lb. (45 kg) bags of cement. Do you have enough load capacity
to transport the cement to your home? If you and your friend each
weigh 220 lb. (99 kg), the calculation would be: 1400 - (2 x 220) - (12
x 100) = 1400 - 440 - 1200 = - 240 lb. No, you do not have enough
cargo capacity to carry that much weight. In metric units, the
calculation would be: 635 kg - (2 x 99 kg) - (12 x 45 kg) = 635 - 198 -
540 = -103 kg. You will need to reduce the load weight by at least
240 lb. (104 kg). If you remove 3-100 lb. (45 kg) cement bags, then
the load calculation would be:

1400 - (2 x 220) - (9 x 100) = 1400 - 440 - 900 = 60 lb. Now you have
the load capacity to transport the cement and your friend home. In
metric units, the calculation would be: 635 kg - (2 x 99 kg) - (9 x
45 kg) = 635 - 198 - 405 = 32 kg.

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 Safety Compliance
Certification Label found on the edge of 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 the Driving chapter of this Owner’s Manual.

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.

WARNING:

Do not exceed the GVWR or the GAWR specified on

the certification label.

The certification label is found on the driver’s door latch pillar.

WARNING:

Towing trailers beyond the maximum recommended

gross trailer weight exceeds the limit of the vehicle and could

result in engine damage, transmission damage, structural damage, loss
of vehicle control, vehicle rollover and personal injury.

Preparing to tow
Use the proper equipment for towing a trailer and make sure it is
properly attached to your vehicle. Contact your authorized dealer or a
reliable trailer dealer as soon as possible if you require assistance.

Hitches
For towing trailers up to 2,000 lb. (907 kg), use a weight carrying hitch
and ball which uniformly distributes the trailer tongue loads through the

2009 B-Series (mbs)
Owners Guide, 1st Printing
USA (fus)

Tires, Wheels and Loading

150

underbody structure. Use a frame-mounted weight distributing hitch for
trailers over 2,000 lb. (907 kg).

Do not install a single or multi-clamp type bumper hitch, or a hitch
which attaches to the axle. Underbody mounted hitches are acceptable if
they are installed properly. Follow the towing instructions of a reputable
rental agency.

Whenever a trailer hitch and hardware are removed, make sure all
mounting holes in the underbody are properly sealed to prevent noxious
gases or water from entering.

Safety chains
Always connect the trailer’s safety chains to the frame or hook retainers
of the vehicle hitch. To connect the trailer’s safety chains, cross the
chains under the trailer tongue and allow slack for turning corners.

If you use a rental trailer, follow the instructions that the rental agency
gives to you.

Do not attach safety chains to the bumper.

Trailer brakes
Electric brakes and manual, automatic or surge-type trailer brakes are
safe if installed properly and adjusted to the manufacturer’s
specifications. The trailer brakes must meet local and Federal
regulations.

WARNING:

Do not connect a trailer’s hydraulic brake system

directly to your vehicle’s brake system. Your vehicle may not

have enough braking power and your chances of having a collision
greatly increase.

The braking system of the tow vehicle is rated for operation at the
GVWR not GCWR.

Trailer lamps
Trailer lamps are required on most towed vehicles. Make sure all running
lights, brake lights, turn signals and hazard lights are working. Contact
your authorized dealer or trailer rental agency for proper instructions
and equipment for hooking up trailer lamps.

Using a step bumper
The optional step bumper is equipped with an integral hitch and requires
only a ball with a 3/4 inch (19 mm) shank diameter. The bumper has a
2,000 lb (907 kg) trailer weight and 200 lb (91 kg) tongue weight
capability.
