1999 Subaru Legacy Owner's Manual - Page 137

Instruments and controls J Rear window wiper and washer switch (Wagon - if equipped) D In freezing weather, be sure the wiper blade is not frozen to the rear window before operating the rear wiper. Attempting to operate the wiper while the blade is frozen to the rear window could cause the wiper motor to burn out. If the wiper blade is frozen to the rear window, turn on the rear window defogger and wait to melt the frozen wiper blade from the rear window before operating the rear wiper. D If the wiper stops during operation because of ice or some other obstruction on the rear window, the wiper motor could burn out even if the wiper switch is turned off. If this occurs, promptly stop the vehicle in a safe place, turn the ignition switch to the "LOCK" position and clean the rear window to allow proper wiper operation. D To prevent the washer motor from overheating, avoid operating the washer switch for more than 10 seconds continuously, or when the washer fluid tank is empty. Check washer fluid level frequently, such as at fuel stops. D Use clean water if windshield washer fluid is unavailable. In areas where water freezes in winter, use SUBARU Windshield Washer Fluid or the equivalent. (See Windshield Washer Fluid section in chapter 10.) Also, when driving the vehicle when there are freezing temperatures, use non-freezing type wiper blades. CAUTION - CONTINUED - 3-21
