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 reactivate the front wiper. The

wiper will operate normally.

REAR WIPER MOTOR PROTECTION FUNCTION

more due to a snowfall.

• Rear wiper operates normally 1 minute after the obstacles are removed with rear wiper OFF.
