Overview
The windshield wiper/washer system is activated by the wiper/washer switch. The following functions/features of the windshield wiper/washer system are
- Windshield wash
- Courtesy wipe
- Windshield wipers (low/high speed)
- Intermittent wipers
- Speed dependent wipers
- Wiper activated exterior lamps
- Rain sensitive wipers (if equipped)
- Rear window wipe
- Rear window wash
- Reverse gear wipe
There are 6 intermittent/sensitivity settings to choose from for the intermittent/rain sensitive wipers.
There are 2 settings to choose from for the rear window wiper operation.
