Instruments and controls
CAUTION
D Do not operate the washer continuously for more than ten se-
conds, or when the washer fluid tank is empty. This may cause
overheating of the washer motor. Check the washer fluid level fre-
quently, such as at fuel stops.
D Do not operate the wipers when the windshield or rear window
is dry. This may scratch the glass, damage the wiper blades and
cause the wiper motor to burn out. Before operating the wiper on
a dry windshield or rear window, always use the windshield
washer.
D In freezing weather, be sure that the wiper blades are not fro-
zen to the windshield or rear window before switching on the
wipers. Attempting to operate the wiper with the blades frozen to
the window glass could cause not only the wiper blades to be
damaged but also the wiper motor to burn out. If the wiper blade
is frozen to the window glass, be sure to operate the defroster or
rear window defogger before turning on the wiper.
D If the wipers stop during operation because of ice or some oth-
er obstruction on the 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 window glass to allow proper wiper opera-
tion.
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 tempera-
tures, use non-freezing type wiper blades.
D Do not clean the wiper blades with gasoline or a solvent, such
as paint thinner or benzene. This will cause deterioration of the
wiper blades.
