WARNING! Do not drive with worn or dirty wiper
blades. They can reduce visibility, making driv-
ing hazardous. Clean the blades regularly to
remove road film and wax build-up. Use an alco-
hol-based cleaning solution and a lint-free cloth,
and wipe along the blades.
Clean all inside and outside windows regularly. Use an alco-
hol-based cleaning solution and wipe dry with either a lint-
free or a chamois cloth. Avoid running the wiper blades over
a dry windshield to prevent scratching the glass. Spray on
washer fluid first. A scratched windshield will reduce visibility.
