2004 MAZDA MODEL B-SERIES brake

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.

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.
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. 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.

Driving while you tow
When towing a trailer:
• Turn off the speed control. The speed control may shut off
automatically when you are towing on long, steep grades.
• Consult your local motor vehicle speed regulations for towing a trailer.
• To 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 transmission section in this
chapter.)
• Under 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 gauge in theInstrument cluster
chapter.
• Anticipate stops and brake gradually.
• Do not exceed the GCWR rating or transmission damage may occur.

4x2 equipped with a manual transmission:
Before you have your vehicle towed:
•Release the parking brake.
• Move the gearshift to the neutral position.
• Turn the key in the ignition to the OFF/UNLOCKED position.
• The maximum recommended speed is 88 km/h (55 mph).
• The maximum recommended distance is unlimited.
• The 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:
• Release the parking brake.
• Turn the key in the ignition to the OFF/UNLOCKED position.
• Place the transmission in N (Neutral).
• Do not exceed a distance of 80 km (50 miles).
• Do not exceed 56 km/h (35 mph) vehicle speed.
• The 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.
CAMPER BODIES
Your pickup is not recommended for slide –in camper bodies.
