2. Press the retaining clip to
disengage the wiper blade, then pull
the wiper blade down toward the

arm (2).

Poor wiper quality can be improved by cleaning the wiper blades and the
windshield. Refer to Windows and wiper blades in the Cleaning
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.
