UNDERSTANDING YOUR INSTRUMENT PANEL 221 Rear Washer Operation - Automatic Temperature Control Only Press and hold the button as long as spray is desired. If the switch is depressed while the wipers are on, the wipers will operate for a few seconds after the switch is released then resume the previously set mode of intermittent wiper or continuous wipe. If the switch is depressed when the wipers are off, the wipers will operate for two cycles, then turn off. NOTE: The washers will stop spraying if the switch is pressed longer than 10 seconds. Adding Washer Fluid The fluid reservoir for the windshield washers and the rear window washer is shared. It is located in the front of the engine compartment on the passenger side and should be checked for fluid level at regular intervals. Fill the reservoir with windshield washer solvent (not radiator antifreeze) and operate the system for a few seconds to flush out the residual water. 4 The washer fluid reservoir will hold a full gallon of fluid when the Low Washer Fluid Light illuminates.
