 To prevent damage to the windshield wiper arms
When lifting the wiper arms away from the windshield pull the driver side
wiper arm upward first, and repeat for the passenger side. When returning
the wipers to their original position, do so from the passenger side first.
 When using an automatic car wash (vehicles with rain-sensing wind-
shield wipers)
Turn off the wiper switch. If the wiper switch is in "AUTO", the wipers may
operate and the wiper blades may be damaged.
