SWITCHES
40
Rain−sensing windshield wipers
1 Automatic control adjuster
2 Washer on
To turn the wipers on, move the lever down until you reach
the desired speed setting.
The ignition switch must be in the “ON” position.
There are 3 settings:
“AUTO” position:
Automatic operation
“LO” position:
Low speed operation
“HI” position:
High speed operation
Automatic operation
The wiper speed is determined by the amount of raindrops
and sunlight detected by the automatic wiper control
sensor.
You may adjust the automatic wiper control sensitivity by
twisting the automatic control adjuster in the “−”
direction, which requires more raindrop volume to start
the wiper, or in the “+” direction, which requires less
raindrop volume to start the wiper.
The sensor is on the inside of the windshield as shown above.
Even if the wiper lever is in the “AUTO” position, the system will
switch to intermittent operations in the following conditions:
When the windshield gets extremely cold (at less than
–10 C [14 F])
When the system malfunctions
However, when the windshield gets extremely hot (at more
than 90 C [194 F]), the wipers do not operate even if the wiper
lever is in the “AUTO” position.
