Maintenance and Care Owner Maintenance Your Mazda's headlights and fog lights have replaceable halogen bulbs. M Replacing Exterior Light Bulbs Replacing a headlight bulb 1. Make sure the ignition switch is turned off and the headlight switch is off. 2. Lift the hood. 3. Do the following procedure when replacing the left headlight bulb. Turn the screws counterclockwise and remove them and the cover. WARNING Xenon Fusion Bulb Replacement: Replacing the xenon fusion bulbs by yourself is dangerous. Because the xenon fusion bulbs require high voltage, you could receive an electric shock if the bulbs are handled incorrectly. Do not replace the xenon fusion bulbs by yourself. Consult an Authorized Mazda Dealer when the replacement is necessary. 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 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 it some other way. Always keep halogen bulbs out of the reach of children. Screw Cover 4. Find the high and low beam bulbs in the rear of the headlight unit. The outboard bulb is the LOW beam, and the inboard one is the HIGH beam. (page 8-36) 8-37
