Description

INFOID:0000000003761617

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.
