Slide the wiper blade onto wiper arm 
until it locks in place.
Rotate the wiper blade into position 
parallel to wiper arm.
Fold the wiper arm backward to rest on 
the windshield. Make sure you hold on 
to the wiper when folding the wiper arm 
back.
!Never open the hood when the wiper 
arm is folded forward.
Hold on to the wiper when folding the

Do not allow the wiper arms to contact 
the windshield glass without a wiper

Make certain that the wiper blades are 
properly installed. Improperly installed 
wiper blades may cause windshield 
damage.
