2004 MAZDA MODEL B2300 TRUCK headlamp

To install the new bulb:
Handle a halogen headlamp bulb carefully and keep out of
children's reach. Grasp the bulb only by its plastic base and do
not touch the glass. The oil from your hands could cause the bulb
to break the next time the headlamps are operated. Always wear
safety glasses while handling bulbs.
NOTE: If the bulb is accidentally touched, it should be cleaned with
rubbing alcohol before being used.
1. With the flat side of the bulb's plastic base facing upward, insert the
glass end of the bulb into the lamp assembly. You may need to turn
the bulb left or right to align the grooves in the plastic base with the
tabs in the lamp assembly. When the grooves are aligned, push the
bulb into the lamp assembly until the plastic base contacts the rear
of the lamp assembly.
2. Install the bulb retaining ring over the plastic base until it contacts
the rear of the socket by rotating clockwise until you feel a ªstop.º
3. Install the electrical connector into the plastic base until it snaps,
locking it into position.
4. Install the headlamp on vehicle, push rearward and secure with two
retainer pins.
5. Turn the headlamps on and make sure they work properly. If the
headlamp was correctly aligned before you changed the bulb, you
should not need to align it again.
Replacing front side marker bulbs

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
all automatic locking retractors on all outboard seating positions as well
as the automatic locking mode for child safety seats on the passenger
front belt. All safety belt assemblies, including retractors, buckles, front
seat 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), LATCH child seat tether anchors and lower
anchors (if equipped), and attaching hardware, should be inspected after

WARNING: Extended idling at high engine speeds can produce
very high temperatures in the engine and exhaust system,
creating the risk of fire or other damage.
WARNING: Do not park, idle, or drive your vehicle in dry grass
or other dry ground cover. The emission system heats up the
engine compartment and exhaust system, which can start a fire.
WARNING: Do not start your vehicle in a closed garage or in
other enclosed areas. Exhaust fumes can be toxic. Always open
the garage door before you start the engine. SeeGuarding
against exhaust fumesin this chapter for more instructions.
WARNING: If you smell exhaust fumes inside your vehicle,
have your dealer inspect your vehicle immediately. Do not drive
if you smell exhaust fumes.
Important safety precautions
When the engine starts, the idle RPM runs faster to warm the engine. If
the engine idle speed does not slow down automatically, have the vehicle
checked.
Before starting the vehicle:
1. Make sure all occupants buckle their safety belts. For more
information on safety belts and their proper usage, refer to the
Seating and Safety Restraintschapter.
2. Make sure the headlamps and electrical accessories are off.

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.
