two positions are wiper low speed and wiper high speed.
See the wiper switch settings table that follows for inter-
mittent delay times.
WARNING! Do not drive with worn or dirty
wiper blades. They can reduce visibility, mak-
ing driving hazardous. Clean blades regularly
to remove road film and wax build-up. Use an
alcohol-based cleaning solution and a lint-
free cloth, and wipe along the blades.
CAUTION:
• Do not use antifreeze or engine coolant in
the windshield washer reservoir—damage to
seals and other components will result.
If the electric pump is operated for a long
period (more than 15 seconds) with a dry res-
ervoir, the pump motor may be damaged.
