Automatic operation (position 1)
The wiper speed is determined by the
amount of raindrops and sunlight detected
by the automatic wiper control sensor.
The automatic wiper control sensor is on
the inside of the windshield as shown
above.
If you feel that the operation of the auto-
matic wiper control is too fast or too slow,
twist the automatic control adjuster in the
"−" direction to lower sensitivity, and "+"
direction to boost the sensitivity.

Even if the wiper lever is in the position
1, the system will switch to intermittent
operations in the following conditions:
D
When the windshield gets extremely
cold (at less than −10_C or 14_F)
D
When the system malfunctions
However, when the windshield gets ex-
tremely hot (at more than 90_C or 194_F),
the wipers do not operate even if the
wiper lever is in the position 1.
When the ignition switch is turned off with
the wiper lever in the position 1, and then
the ignition switch is turned on again, the
automatic operation may not work even if
raindrops are on the windshield.
In this case, move the lever to another
position and return it to the position 1
again.
