2007 MAZDA MODEL B3000 TRUCK maintenance

Safety belt extension assembly
If the safety belt assembly is too short for you, even when fully
extended, 20 cm (8 inches) can be added to the safety belt assembly by
adding a safety belt extension assembly. Safety belt extension assemblies
can be obtained from your authorized Mazda dealership.
Use only extensions manufactured by the same supplier as the safety
belt. Manufacturer identification is located at the end of the webbing on
the label. Also, use the safety belt extension only if the safety belt is too
short for you when fully extended.
NOTE:Do not use extensions to change the fit of the shoulder belt
across the torso.
Safety belt maintenance
Inspect the safety belt systems periodically to make sure they work
properly and are not damaged.
NOTE: If unsure about the proper procedures, bring your vehicle to an
authorized Mazda dealership for inspection. Inspect the safety belts to
make sure there are no nicks, tears or cuts, replacing if necessary. Check
the automatic locking retractor on the passenger outboard seating position.
All safety belt assemblies, including retractors, buckles, front safety belt
buckle assemblies, buckle support assemblies (slide bar-if equipped),
shoulder belt height adjusters (if equipped), shoulder belt guide on
seatback (if equipped), child safety seat tether bracket assemblies (if
equipped), and attaching hardware, should be inspected after a collision.
Mazda recommends that all safety belt assemblies used in vehicles involved
in a collision be replaced. However, if the collision was minor and an
authorized Mazda technician finds that the belts do not show damage and
continue to operate properly, they do not need to be replaced. Safety belt
assemblies not in use during a collision should also be inspected and
replaced if either damage or improper operation is noted.
The energy absorbing functions may have been activated in a collision so
the restraints should be examined; if the front airbags have deployed, the
pretensioners have also deployed and must be replaced — regardless of
whether there was an occupant in the passenger seat or not.
WARNING: Failure to inspect and if necessary replace the
safety belt assembly under the above conditions could result in
severe personal injuries in the event of a collision.
Refer to Interior in theCleaning chapter.

The airbags inflate and deflate
rapidly upon activation. After airbag
deployment, it is normal to notice a
smoke-like, powdery residue or
smell the burnt propellant. This may
consist of cornstarch, talcum
powder (to lubricate the bag) or
sodium compounds (e.g., baking
soda) that result from the
combustion process that inflates the
airbag. Small amounts of sodium
hydroxide may be present which
may irritate the skin and eyes, but
none of the residue is toxic.
While the system is designed to help
reduce serious injuries, it may also
cause minor abrasions, swelling or temporary hearing loss. Because
airbags must inflate rapidly and with considerable force, there is the risk
of death or serious injuries such as fractures, facial and eye injuries or
internal injuries, particularly to occupants who are not properly
restrained or are otherwise out of position at the time of airbag
deployment. Thus, it is extremely important that occupants be properly
restrained as far away from the airbag module as possible while
maintaining vehicle control.WARNING: Several airbag system components get hot after
inflation. Do not touch them after inflation or you may be
burned.
WARNING: If the air bag has deployed, the air bag will not
function again and must be replaced immediately. If the air bag
is not replaced, the unrepaired area will increase the risk of
injury in a collision.
Determining if the system is operational
The SRS uses readiness lights in the instrument cluster or a tone to
indicate the condition of the system. Refer to the Airbag readiness
section in the Instrumentation chapter. Routine maintenance of the
airbag is not required.

Power is supplied to all four wheels
through a transfer case or power
transfer unit. 4WD vehicles allow
you to select different drive modes
as necessary. Information on
transfer case operation and shifting
procedures can be found in the
Drivingchapter. Information on
transfer case maintenance can be found in the Maintenance and
Specifications chapter. You should become thoroughly familiar with this
information before you operate your vehicle.
On some 4WD models, the initial shift from two-wheel drive to 4WD
while the vehicle is moving can cause a momentary clunk and ratcheting
sound. These sounds are normal as the front drivetrain comes up to
speed and is not cause for concern.
WARNING: Do not become overconfident in the ability of 4WD
and AWD vehicles. Although a 4WD or AWD vehicle may
accelerate better than two-wheel drive vehicle in low traction
situations, it won’t stop any faster than two-wheel drive
vehicles. Always drive at a safe speed.
How your vehicle differs from other vehicles
SUV and trucks can differ from
some other vehicles in a few
noticeable ways. Your vehicle may
be:
• Higher – to allow higher load
carrying capacity and to allow it
to travel over rough terrain
without getting hung up or
damaging underbody components.
• Shorter – to give it the capability
to approach inclines and drive
over the crest of a hill without
getting hung up or damaging
underbody components. All other
things held equal, a shorter
wheelbase may make your vehicle
quicker to respond to steering inputs than a vehicle with a longer
wheelbase.

TIRE CARE
Inspecting your tires
Periodically inspect the tire treads for uneven or excessive wear and
remove objects such as stones, nails or glass that may be wedged in the
tread grooves. Check for holes or cuts that may permit air leakage from
the tire and make necessary repairs. Also inspect the tire sidewalls for
cracking, cuts, bruises and other signs of damage or excessive wear. If
internal damage to the tire is suspected, have the tire demounted and
inspected in case it needs to be repaired or replaced. For your safety,
tires that are damaged or show signs of excessive wear should not be
used because they are more likely to blow out or fail.
Improper or inadequate vehicle maintenance can cause tires to wear
abnormally. Inspect all your tires, including the spare, frequently, and
replace them if one or more of the following conditions exist:
Tire wear
When the tread is worn down to
1/16th of an inch (2 mm), tires must
be replaced to help prevent your
vehicle from skidding and
hydroplaning. Built-in treadwear
indicators, or “wear bars”, which
look like narrow strips of smooth
rubber across the tread will appear
on the tire when the tread is worn
down to 1/16th of an inch (2 mm).
When the tire tread wears down to
the same height as these “wear bars”, the tire is worn out and must be
replaced.
Damage
Periodically inspect the tire treads and sidewalls for damage (such as
bulges in the tread or sidewalls, cracks in the tread groove and
separation in the tread or sidewall). If damage is observed or suspected
have the tire inspected by a tire professional. Tires can be damaged
during off-road use, so inspection after off-road use is also
recommended.

Tire rotation
Rotating your tires at the recommended interval (as indicated in the
Scheduled maintenancesection of theMaintenance and
Specifications chapter) will help your tires wear more evenly, providing
better tire performance and longer tire life.

TIRE PRESSURE MONITORING SYSTEM (TPMS)
Each tire, including the spare (if
provided), should be checked
monthly when cold and inflated to
the inflation pressure recommended
by the vehicle manufacturer on the
vehicle placard or tire inflation pressure label. (If your vehicle has tires
of a different size than the size indicated on the vehicle placard or tire
inflation pressure label, you should determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire
pressure monitoring system (TPMS) that illuminates a low tire pressure
telltale when one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure telltale illuminates, you should
stop and check your tires as soon as possible, and inflate them to the
proper pressure. Driving on a significantly under-inflated tire causes the
tire to overheat and can lead to tire failure. Under-inflation also reduces
fuel efficiency and tire tread life, and may affect the vehicle’s handling
and stopping ability.
Please note that the TPMS is not a substitute for proper tire
maintenance, and it is the driver’s responsibility to maintain correct tire
pressure, even if under-inflation has not reached the level to trigger
illumination of the TPMS low tire pressure telltale.
The Tire Pressure Monitoring System complies with part 15 of the FCC
rules and with RSS-210 of Industry Canada. Operation is subject to the
following two conditions: (1) This device may not cause harmful
interference, and (2) This device must accept any interference received,
including interference that may cause undesired operation.WARNING: The Tire Pressure Monitoring System is NOT a
substitute for manually checking tire pressure. The tire
pressure should be checked periodically (at least monthly)
using a tire gauge, see Inflating your tiresin this chapter.
Failure to properly maintain your tire pressure could increase
the risk of tire failure, loss of control, vehicle rollover and
personal injury.

Servicing after towing
If you tow a trailer for long distances, your vehicle will require more
frequent service intervals. Refer to yourscheduled maintenance
information for more information.
Trailer towing tips
• Practice 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.
• Allow more distance for stopping with a trailer attached.
• The trailer tongue weight should be 10–15% of the loaded trailer
weight.
• If you will be towing a trailer frequently in hot weather, hilly
conditions, at GCWR, or any combination of these factors, consider
refilling your rear axle with synthetic gear lube if not already so
equipped. Refer to the Maintenance and specifications chapter for
the lubricant specification. Remember that regardless of the rear axle
lube used, do not tow a trailer for the first 500 miles (800 km) of a
new vehicle, and that the first 500 miles (800 km) of towing be done
at no faster than 70 mph (112 km/h) with no full throttle starts.
• After you have traveled 50 miles (80 km), thoroughly check your
hitch, electrical connections and trailer wheel lug nuts.
• To 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).
• Vehicles 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:
• do not allow the static water level to rise above the bottom edge of
the rear bumper.
• do not allow waves to break higher than 6 inches (15 cm) above the
bottom edge of the rear bumper.
