cooling MAZDA MODEL B-SERIES 2002 Owners Manual (in English)

²To reduce humidity buildup inside the vehicle in warm weather
conditions, don't drive with the climate control system in the OFF
position.
²Under normal weather conditions, your vehicle's climate control
system should be left in any position other than the MAX A/C or OFF
when the vehicle is parked. This allows the vehicle to ªbreatheº
through the outside air inlet duct.
²Under snowy or dirty weather conditions, your vehicle's climate
control system should be left in the OFF position when the vehicle is
parked. This allows the climate control system to be free from
contamination of outside pollutants.
²If your vehicle has been parked with the windows closed during warm
weather conditions, the air conditioner will perform more efficiently in
cooling the vehicle if driven for two or three minutes with the
windows open. This will force most of the hot, stale air out of the
vehicle. Once the vehicle has been ªaired outº, operate the climate
control system as desired.
²Do not put objects under the front seat which may interfere with the
airflow to the rear seats (if equipped).
²Remove any snow, ice or leaves from the air intake area (at the
bottom of the windshield and underneath the hood).
²Do not place objects over the defroster outlets. These objects can
block airflow and reduce visibility through your windshield. Avoid
placing small objects on top of the instrument panel. These objects
may fall down into the defroster outlets and block airflow, in addition
to, damaging the climate control system.
To aid in side window defogging/demisting in cold weather conditions:
1. Select the position that distributes air through the Panel and Floor.
2. Set the temperature control to full heat.
3. Set the fan speed to full fan.
4. Direct the outer panel vents towards the side windows.
5. To increase airflow to the outer panel vents, close the central panel
vents.
Do not place objects on top of the instrument panel as these
objects may become projectiles in a collision or sudden stop.

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.

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.
