FRONT WIPER MOTOR PROTECTION FUNCTION
• IPDM E/R may stop the front wiper to protect the front wiper motor if any obstruction (operation resistance)
such as a large amount of snow is detected during the front wiper operation.
• At that time turn OFF the front wiper and remove the foreign object. Then wait for approximately 20 seconds
or more and reactivate the front wiper. The wiper will operate normally.
