Maintenance and service/Replacement of wiper blades
Replacement of wiper blades
Grease, wax, insects, or other material on
the windshield or the wiper blade results in
jerky wiper operation 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 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 windshield is clean if beads do not
form when you rinse the windshield with
water.
CAUTION
. Do not clean the wiper blades
with gasoline or a solvent, such
as paint thinner or benzine. This
will cause deterioration of the
wiper blades.
. When you are going to raise the
passenger-side wiper arm, first
raise the driver-side wiper arm.
Otherwise, the passenger-side
wiper assembly and driver-side
wiper assembly will touch each
other, possibly resulting in
scratches.
. Return the passenger-side wiper
arm to its original position before
returning the driver-side wiper
arm to its original position.
Otherwise, the passenger-side
wiper assembly and driver-side
wiper assembly will touch each
other, possibly resulting in
scratches.
. While removing the wiper blades
from the wiper arms, do not
return the wiper arms to the
original positions. Otherwise,
the windshield surface may be
scratched.
. When returning the raised wiper
arms to the original positions,
carefully return the wiper arms
on the windshield by hand. You
should not return the wiper arms
to the windshield only by the
return spring. Otherwise, the wi-
per arms may be deformed and/
or the windshield surface may be
scratched.
