warning MAZDA MODEL B-SERIES 2002 (in English) Repair Manual

WARNING: Exceeding any vehicle weight rating limitation
could result in serious damage to the vehicle and/or personal
injury.
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, with a higher center of gravity,
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 has the capability to 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.
Calculating the load your vehicle can carry/tow
1. Use the appropriate maximum gross combined weight rating
(GCWR) chart to find the maximum GCWR for your type engine and
rear axle ratio.
2. Weigh your vehicle as you customarily operate the vehicle without
cargo. To obtain correct weights, try taking your vehicle to a
shipping company or an inspection station for trucks.
3. Subtract your loaded vehicle weight from the maximum GCWR on
the following charts. This is the maximum trailer weight your vehicle
can tow and must fall below the maximum shown under maximum
trailer weight on the chart.
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.
Driving
171

WARNING: Do not exceed the GVWR or the GAWR specified on
the certification label.
WARNING: Towing trailers beyond the maximum recommended
gross trailer weight could result in engine damage,
transmission/axle damage, structural damage, loss of control,
and personal injury.
Preparing to tow
Use the proper equipment for towing a trailer, and make sure it is
properly attached to your vehicle. See your dealer or a reliable trailer
dealer if you require assistance.
Hitches
For towing trailers up to 907 kg (2,000 lb), use a weight carrying hitch
and ball which uniformly distributes the trailer tongue loads through the
underbody structure. Use a frame-mounted weight distributing hitch for
trailers over 907 kg (2,000 lb).
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.
Driving
175

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 your
trailer lamps conform to local and Federal regulations. See your 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 19 mm (3/4 inch) shank diameter. The bumper has a
907 kg (2,000 lb.) trailer weight and 91 kg (200 lb.) tongue weight
capability.
The rated capacities (as shown in this guide) for trailer towing with the
factory bumper are only valid when the trailer hitch ball is installed
directly into the ball hole in the bumper. Addition of bracketry to either
lower the ball hitch position or extend the ball hitch rearward will
significantly increase the loads on the bumper and its attachments. This
can result in the failure of the bumper or the bumper attachments. Use
of any type of hitch extensions should be considered abuse.
Trailer tow connector
The trailer tow connector is located
under the rear bumper, on the
driver's side of the vehicle.

Temporary spare tire information
Your vehicle may have a temporary or conventional spare tire. The
temporary spare tire for your vehicle is labeled as such. It is smaller than
a regular tire and is designed for emergency use only. Replace this tire
with a full-size tire as soon as possible.
It is not recommended that the vehicle be operated in 4WD modes with
a temporary spare. If 4WD operation is necessary, do not operate above
speeds of 16 km/h (10 mph) or for distances above 80 km (50 miles).
WARNING: If you use the temporary spare tire continuously or
do not follow these precautions, the tire could fail, causing you
to lose control of the vehicle, possibly injuring yourself or
others.
When driving with the temporary spare tiredo not:
²exceed 80 km/h (50 mph) under any circumstances
²load the vehicle beyond maximum vehicle load rating listed on the
Safety Compliance Label
²tow a trailer
²use tire chains
²drive through an automatic car wash, because of the vehicle's reduced
ground clearance
²try to repair the temporary spare tire or remove it from its wheel rim
²use the wheel for any other type of vehicle
Conventional spare tire information
If you have the conventional spare tire, you can use it as a spare or a
regular tire. The spare is identical to the other tires on your vehicle,
although the wheel may not match.

full size tire should be stowed and tied down in the pickup box bed
until it can be repaired.
5. If removed, install the spare tire carrier lock on the access hole
above the bumper.
Tire change procedure
WARNING:
When one of the front wheels is off the ground, the
transmission alone will not prevent the vehicle from moving or
slipping off the jack, even if the vehicle is in P (Park)
(automatic transmission) or R (Reverse) (manual transmission).
WARNING: To prevent the vehicle from moving when you
change a tire, be sure the parking brake is set, then block (in
both directions) the wheel that is diagonally opposite (other
side and end of the vehicle) to the tire being changed.
WARNING: If the vehicle slips off the jack, you or someone
else could be seriously injured.
1. Park on a level surface, activate
hazard flashers and place
gearshift lever in P (Park)
(automatic transmission) or 1
(First) (manual transmission).
2. Set the parking brake and turn
engine OFF.
3. Block the diagonally opposite
wheel.

JUMP STARTING YOUR VEHICLE
WARNING: The gases around the battery can explode if
exposed to flames, sparks, or lit cigarettes. An explosion could
result in injury or vehicle damage.
WARNING: Batteries contain sulfuric acid which can burn skin,
eyes, and clothing, if contacted.
Do not attempt to push-start your vehicle. Automatic
transmissions do not have push-start capability; also, the
catalytic conveter may become damaged.
Preparing your vehicle
When the battery is disconnected or a new battery is installed, the
transmission must relearn its adaptive strategy. As a result of this, the
transmission may shift firmly. This operation is considered normal and
will not affect function or durability of the transmission. Over time, the
adaptive learning process will fully update transmission operation to its
optimum shift feel.
1.Use only a 12±volt supply to start your vehicle.
2. Do not disconnect the battery of the disabled vehicle as this could
damage the vehicle's electrical system.
3. Park the booster vehicle close to the hood of the disabled vehicle
making sure the two vehiclesdo nottouch. Set the parking brake on
both vehicles and stay clear of the engine cooling fan and other
moving parts.
4. Check all battery terminals and remove any excessive corrosion
before you attach the battery cables. Ensure that vent caps are tight
and level.
5. Turn the heater fan on in both vehicles to protect any electrical
surges. Turn all other accessories off.

the carburetor/fuel injection system.Do notuse fuel lines, engine
rocker covers or the intake manifold asgroundingpoints.
WARNING: Do not connect the end of the second cable to the
negative (-) terminal of the battery to be jumped. A spark may
cause an explosion of the gases that surround the battery.
5. Ensure that the cables are clear of fan blades, belts, moving parts of
both engines, or any fuel delivery system parts.
