SWITCHES When the outside temperature is below 25 _ C (77 _ F), operating the wipers will automatically turn on the outside rear view mirror defogger. The outside rear view mirror defogger turns off 15 minutes after the wiper stops operating. In cold weather, warm the windshield with the defroster before using the washer. This will help prevent icing, which could block your vision. HEADLIGHT CLEANER SWITCH 12sa02 NOTICE Do not operate the wipers if the windshield is dry. It may scratch the glass. To spray fluid on the headlights, push the switch with the headlights on. The ignition switch must be in the "ON" position. The low washer fluid warning light in the instrument cluster comes on when the fluid level in the tank becomes very low. For information on adding washer fluid, see "Adding washer fluid" on page 363. If you push the windshield washer switch with the headlights on, the headlight cleaner operates once automatically. NOTICE Do not turn the headlight cleaner on with the washer fluid tank empty. It may cause the cleaner motor to overheat. 29
