2004 MAZDA MODEL B4000 4WD TRUCK transmission

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 door pillar. The GVW
must never exceed the GVWR.
WARNING: Exceeding the Safety Certification Label axle
weight rating limits could result in substandard vehicle
handling, 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 weighing more than 680 kg
[1,500 lbs]).The GCW must never exceed the GCWR.

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.

Maximum trailer weight is shown. The combined weight of the
completed towing vehicle (including hitch, passengers and cargo) and
the loaded trailer must not exceed the Gross Combined Weight Rating

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. See your dealer or a reliable trailer
dealer if you require assistance.

Driving while you tow
When towing a trailer:
²Turn off the speed control. The speed control may shut off
automatically when you are towing on long, steep grades.
²Consult your local motor vehicle speed regulations for towing a trailer.
²To eliminate excessive shifting, use a lower gear. This will also assist
in transmission cooling. (For additional information, refer to the
Driving with a 5±speed automatic transmissionsection in this
chapter.)
²Under extreme conditions with large frontal trailers, high outside
temperatures and highway speeds, the coolant gauge may indicate
higher than normal coolant temperatures. If this occurs, reduce speed
until the coolant temperature returns to the normal range. Refer to
Engine coolant temperature gaugein theInstrument cluster
chapter.
²Anticipate stops and brake gradually.
²Do not exceed the GCWR rating or transmission damage may occur.
Servicing after towing
If you tow a trailer for long distances, your vehicle will require more
frequent service intervals. Refer to your service maintenance section for
more information.
Trailer towing tips
²Practice turning, stopping and backing up before starting on a trip to
get the feel of the vehicle trailer combination. When turning, make
wider turns so the trailer wheels will clear curbs and other obstacles.
²Allow more distance for stopping with a trailer attached.
²The trailer tongue weight should be 10±15% of the loaded trailer
weight.
Driving
134

²After you have traveled 80 km (50 miles), thoroughly check your
hitch, electrical connections and trailer wheel lug nuts.
²To aid in engine/transmission cooling and A/C efficiency during hot
weather while stopped in traffic, place the gearshift lever in P (Park)
(automatic transmission) or N (Neutral) (manual transmissions).
²Vehicles with trailers should not be parked on a grade. If you must
park on a grade, place wheel chocks under the trailer's wheels.
Launching or retrieving a boat
Disconnect the wiring to the trailer before backing the trailer
into the water. Reconnect the wiring to the trailer after the
trailer is removed from the water.
When backing down a ramp during boat launching or retrieval:
²do not allow the static water level to rise above the bottom edge of
the rear bumper.
²do not allow waves to break higher than 15 cm (6 inches) above the
bottom edge of the rear bumper.
Exceeding these limits may allow water to enter vehicle components:
²causing internal damage to the components.
²affecting driveability, emissions and reliability.
Replace the rear axle lubricant any time the axle has been submerged in
water. Rear axle lubricant quantities are not to be checked or changed
unless a leak is suspected or repair required.
RECREATIONAL TOWING
Follow these guidelines if you have a need for recreational towing. An
example of recreational towing would be towing your vehicle behind a
motorhome. These guidelines are designed to ensure that your
transmission is not damaged.
4x2 equipped with a manual transmission:
Before you have your vehicle towed:
²Release the parking brake.
²Move the gearshift to the neutral position.
²Turn the key in the ignition to the OFF/UNLOCKED position.
²The maximum recommended speed is 88 km/h (55 mph).
²The maximum recommended distance is unlimited.
Driving
135

²The vehicle must be towed in the forward position to ensure no
damage is done to the internal transfer case components.
In addition, it is recommended that you follow the instructions
provided by the aftermarket manufacturer of the towing
apparatus if one has been installed.
4x2 equipped with automatic transmission and 4x4 vehicles:
4x2 vehicles with automatic transmissions or 4x4 vehicles with an
electronic-shift transfer case and automatic transmission, follow these
guidelines for recreational towing:
²Release the parking brake.
²Turn the key in the ignition to the OFF/UNLOCKED position.
²Place the transmission in N (Neutral).
²Do not exceed a distance of 80 km (50 miles).
²Do not exceed 56 km/h (35 mph) vehicle speed.
²The vehicle must be towed in the forward position to ensure no
damage is done to the internal transfer case components.
If a distance of 80 km (50 miles) or a speed of 56 km/h (35 mph) must
be exceeded, you must disconnect the front (4x4 only) and rear
driveshafts. Mazda recommends the driveshafts be removed/installed only
by a qualified technician. See your local dealer for driveshaft
removal/installation.
Improper removal/installation of the driveshaft can cause
transmission fluid or transfer case fluid loss, damage to the
driveshaft and internal transmission and transfer case
components.

Your pickup is not recommended for slide±in camper bodies.
