Driving Your Mazda Switches and Controls CAUTION Ø Do not shade the light sensor by adhering a sticker or a label on the windshield. Otherwise the light sensor will not operate correctly. NOTE l Light sensor l l Ø The light sensor also works as a rain sensor for the auto-wiper control. Keep hands and scrapers clear of the windshield when the ignition switch is in the ON position as fingers pinched or the wipers and wiper blades damaged when they activate automatically. If you are going to clean the windshield, be sure the wipers are turned off completely - this is particularly important when clearing ice and snow - when it is particularly tempting to leave the engine running. The light may not turn off immediately even if the surrounding area becomes well-lit because the light sensor determines that it is nighttime if the surrounding area is continuously dark for several minutes such as inside long tunnels, traffic jams inside tunnels, or in indoor parking lots. In this case, the light turns off if the light switch is turned to the OFF position. When the headlight switch is in the AUTO position and the ignition switch is turned to the ACC or LOCK position, the headlights, other exterior lights and dashboard illumination will turn off. The timing for turning on the headlights, other exterior lights and dashboard illumination can be delayed by adjusting the sensitivity of the light sensor. Consult an Authorized Mazda Dealer regarding sensor adjustment. Xenon fusion headlight bulbs í The low-beam bulbs of the headlights have xenon fusion bulbs that produce a bright white beam over a wide area. WARNING Do not replace the xenon fusion bulbs yourself: Replacing the xenon fusion bulbs yourself is dangerous. Because the xenon fusion bulbs require high voltage, you could receive an electric shock if the bulbs are handled incorrectly. Consult an Authorized Mazda Dealer when the replacement is necessary. NOTE If the headlights flicker, or the brightness weakens, the bulb-life may be depleted and a replacement is necessary. Consult an Authorized Mazda Dealer. í Some models. 5-59
