1. WIPER CONTROL
2. CAUTIONS ON RAIN SENSOR
When the wiper switch is in the AUTO position, the wiper will operate for 1 cycle if the initial engine
start is made. This may cause the wiper blades to wear prematurely. Therefore, other than rainy
days, set the switch to the OFF position. Especially during the winter time, check if the wiper blades
are not frozen to the windshield.
Operating the wiper with the blades frozen can damage the wiper motor.
If you operate the wipers when the windshield is dry without spraying washer fluid, the windshield
can be scratched and the wiper blades can wear prematurely. Use the wiper with the washer fluid
when the windshield is dry.
When it does not rain, turn the wiper switch to the OFF position.
Turn the wiper switch to the OFF position before any car wash to avoid unwanted operation of the
wipers. -
