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 “stop.”
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 1. Open the hood.
2. At the back of the headlamp, pry up the two retainer pins to
release the headlamp assembly
from the vehicle and pull
headlamp forward.

SCHEDULE II—SPECIAL OPERATING CONDITIONS
If your driving habits FREQUENTLYinclude one or more of the
following conditions:
• Short trips of less than 10 miles (16 km) when outside temperatures
remain below freezing.
• Towing a trailer, or carrying maximum loads.
• Operating in severe dust conditions.
• Operating during hot weatherin stop-and-go “rush hour”traffic.
• Extensive idling, such as police, taxi or door-to-door delivery service.
• High speed operation with a fully loaded vehicle (max. GVW).
• Off-road operation
Change ENGINE OIL AND OIL FILTER every 3 months or 3,000 miles
(4,800 km) whichever occurs first.
NOTE: Idling the engine for extended periods will accumulate more
hours of use on your vehicle than is actually indicated by the mileage
odometer. Consequently, the odometer reading can be often misleading
when determining the right time to change your engine oil and filter. If
you are using your vehicle in a manner which allows it to remain
stationary while the engine is running for long periods (door-to-door
delivery, taxi, police, power/utility company trucks, or similar duty), then
Mazda recommends you increase the frequency of oil and filter changes
to an interval equivalent to 200 ENGINE HOURS or use. Since most
vehicles are not equipped with hour-meters, it may be necessary for you
to approximate your idle time and plan oil/filter changes accordingly.
