Do not move the wipers manually
across the windshield as this may
cause damage to the wiper system.
Inspect the wiper arm pivots on a

pivot points as necessary.
Replacing wiper blades
If the wiper blades do not work
properly after cleaning,
replacement of the blade assembly
or the blade element may be
necessary.
To replace the wiper blades:
1. Pull the wiper arm away from
the windshield and lock it into the
service position.
2. Turn the blade at an angle from
the wiper arm. Depress the lock
tab to release the wiper blade and
pull the wiper blade down toward
the windshield to remove it from
the arm.
3. Attach the new wiper to the
wiper arm and press it into place
until a click is heard.
