CHANGING THE WIPER BLADES
1. Pull the wiper blade and arm
away from the glass. Turn the blade
at a right angle to the arm.
2. Squeeze the locking tabs to
release the blade from the arm and
pull the blade away from the arm to
remove it.
3. Attach the new blade to the arm and snap it into place.
Replace wiper blades at least once per year for optimum performance.
Poor wiper quality can be improved by cleaning the wiper blades and the
windshield, refer toWindows and wiper bladesin theCleaning
chapter.
To prolong the life of the wiper blades, it is highly recommended to
scrape off the ice on the windshield before turning on the wipers. The
layer of ice has many sharp edges and can damage the micro edge of the
wiper rubber element.
