Flash-to-Pass This feature lets you use the high-beam headlamps to signal a driver in front of you that you want to pass. It works even if the headlamps are in the automatic position. To use it, pull the turn signal lever toward you, then release it. If the headlamps are in the automatic position or on low beam, your high-beam headlamps turn on. They will stay on as long as you hold the lever toward you. The high-beam indicator on the instrument panel cluster comes on. Release the lever to return to normal operation. Heavy snow or ice can overload the wiper motor. A circuit breaker will stop the motor until it cools down. Clear away snow or ice to prevent an overload. Turn the band with the wiper symbol to control the windshield wipers. 8(Mist): Turn the band to mist for a single wiping cycle. Hold it there until the wipers start. Then let go. The wipers stop after one wipe. Hold the band on mist longer, for more wipe cycles. To stop the wipers, move the band to off. 9(Off): 6 (Delay): Windshield Wipers Clear ice and snow from the wiper blades before using them. If they are frozen to the windshield, gently loosen or thaw them. Damaged wiper blades may not clear the windshield well, making it harder to see and drive safely. If the blades do become damaged, install new blades or blade inserts. For more information, see Windshield Wiper Blade Replacement on page 5-57. Turn the band to adjust the delay time. The delay between wiping cycles becomes shorter as the band is moved to the top of the lever. This can be very useful in light rain or snow. Turn the band away from you to the first solid band past the delay settings, for steady wiping at low speed. 6 (Low Speed): ? (High Speed): Turn the band further, to the second solid band past the delay settings, for high-speed wiping. 3-9
