2002 MAZDA MODEL B-SERIES trailer

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.

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.

Driving while you tow
When towing a trailer:
²Ensure that you turn off your 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.
²Use a lower gear when towing up or down steep hills. This will
eliminate excessive downshifting and upshifting for optimum fuel
economy and transmission cooling.
²Anticipate stops and brake gradually.
Exceeding the GCWR rating may cause internal transmission
damage and void your warranty coverage.
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 no more than 10±15% of the
loaded trailer weight.
²After you have traveled 80 km (50 miles), thoroughly check your
hitch, electrical connections and trailer wheel lug nuts.
²When stopped in traffic for long periods of time in hot weather, place
the gearshift in P (Park) (automatic transmissions) or N (Neutral)
(manual transmissions). This aids engine cooling and air conditioner
efficiency.
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
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 critical vehicle
components, adversely affecting driveability, emissions, reliability and
causing internal transmission damage.
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.
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.
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.
