Maintenance and service

Never use engine coolant as washer fluid be-cause it could cause paint damage. Replacement of windshield wiper
blades
Grease, wax, insects, or other material on the wind-
shield or the wiper blade results in jerky wiper opera-
tion and streaking on the glass. If you cannot remove
the streaks after operating the windshield washer or if
the wiper operation is jerky, clean the outer surface of
the windshield (or rear window) and the wiper blades
using a sponge or soft cloth with a neutral detergent or
mild-abrasive cleaner. After cleaning, rinse the wind-
shield and wiper blades with clean water. The wind-
shield is clean if beads do not form when you rinse the
windshield with water.
Do not clean the wiper blades with gasoline or
a solvent, such as paint thinner or benzene.
This will cause deterioration of the wiper
blades.
If you cannot eliminate the streaking even after follow-
ing this method, replace the wiper blades using the fol-
lowing procedures:
1. Raise the wiper arm off the windshield.
Washer Fluid Concentration Freezing Temperature
30% 10.4 °F (–12 °C)
50% –4 °F (–20 °C)
100% –49 °F (–45 °C)
