2003 MAZDA MODEL B2300 hood open

WARNING: Handling Halogen Bulbs: When a halogen bulb
breaks, it is dangerous. These bulbs contain pressurized gas. If
one is broken, it will explode and serious injuries could be
caused by the flying glass. If the glass portion of the bulb is
touched with bare hands, body oil could cause the bulb to
overheat and explode when lit. Never touch the glass portion of
the bulb with your bare hands and always wear eye protection
when handling or working around halogen bulbs.
Children and Halogen Bulbs: Playing with a halogen bulb is
dangerous. Serious injuries could be caused by dropping a
halogen bulb or breaking in some other way. Always keep
halogen bulbs out of the reach of children.
To remove the headlamp bulb:
1. Make sure headlamp switch is in
OFF position, then 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.
3. Remove the bulb retaining ring
by rotating it counterclockwise
(when viewed from the rear) to
free it from the bulb socket, and
slide the ring off the plastic
base. Keep the ring to retain the
new bulb.
4. Without turning, remove the old
bulb by gently pulling it straight
back out of the lamp assembly.

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.

OVERHEATING
If the temperature gauge indicates overheating and you experience
power loss, you hear a loud knocking or pinging noise, the engine is
probably too hot.
If this happens:
1. Drive safely to the side of the road and park off the right-of-way.
2. Shift the automatic transmission into P (Park) or the manual
transmission into the neutral position, and apply the parking brake.
3. Turn off the air conditioner.
WARNING: Steam from an overheated engine is dangerous. The
escaping steam could seriously burn you. Open the hood ONLY
after steam is no longer escaping from the engine.
4. Check whether coolant or steam is escaping from under the hood or
from the engine compartment.
²If steam is coming from the engine compartment:do not go near
the front of the vehicle. Stop the engine, then turn the ignition switch
Roadside Emergencies
151

to the ON position without starting the engine. The radiator cooling
fans will start to cool the engine.
²If neither coolant nor steam is escaping:open the hood and idle
the engine until it cools. If this does not lower the temperature, stop
the engine and let it cool.
5. Check the coolant level. If it is low, look for leaks in the radiator
hoses and connections, heater hoses and connections, radiator and
water pump.
If you find a leak or other damage, or if coolant is still leaking, stop the
engine and call an Authorized Mazda dealer.
SeeAdding coolantin theMaintenance and specificationssection. If
you find no problems, the engine is cool and no leaks are obvious,
carefully add coolant as required.
WARNING: When the engine and radiator are hot, scalding
coolant and steam may shoot out under pressure and cause
serious injury. Do not remove the cooling system cap when the
engine and radiator are hot.
Note:If the engine continues to overheat or frequently overheats, have
the cooling system inspected. The engine could be seriously damaged
unless repairs are made.
CHANGING THE TIRES
If you get a flat tire while driving, do not apply the brake heavily.
Instead, gradually decrease your speed. Hold the steering wheel firmly
and slowly move to a safe place on the side of the road.
WARNING: The use of tire sealants is not recommended and
may compromise the integrity of your tires.
Conventional spare tire information
If you have the conventional spare tire, you can use it as a spare or a
regular tire. The spare is identical to the other tires on your vehicle,
although the wheel may not match.
