CLEANING - WIPER & WASHER SYSTEM
WIPER SYSTEM
The squeegees of wiper blades exposed to the ele-
ment s for a long time tend to lose their wiping effec-
tiveness. Per iodic clea ning of th e squ eegees is
su ggest ed t o r emove a ny deposit s of salt or r oad film.
The wiper blades, arms, a nd win dsh ield glass shou ld
only be clea ned using a sponge or soft clot h and
windshield wa sh er fluid, a m ild det ergent, or a non-
abra sive clean er. If th e wiper blades cont inu e t o
leave streaks, sm ears, hazing, or beading on the
gla ss aft er th orough clea ning of th e squeegees and
the glass, the entire wiper blade assembly must be
repla ced.
CAUTION: Protect the rubber squeegees of the
wiper blades from any petroleum-based cleaners,
solvents, or contaminants. These products can rap-
idly deteriorate the rubber squeegees.
WASHER SYSTEM
If the washer system is conta minated with foreign
mater ial, drain th e washer reser voir by removing the
washer pum p/m otor from the reservoir. Clean foreign
mater ial fr om the inside of the washer pump/motor
inlet nipple and th e wa sher reservoir u sing clean
washer fluid, a mild deter gent , or a non-abr asive
clean er. F lush for eign materia l from the washer sys-
tem plumbing by first discon necting the wa sh er
hoses from the wa sh er nozzles, t hen runn ing th e
washer pump/motor to run clea n washer fluid or
water t hrough the system. P lugged or r estricted
washer n ozzles sh ould be carefully ba ck-flushed
using compressed air. If the washer nozzle obstr uc-
tion cannot be clear ed, repla ce the washer n ozzle.
CAUTION: Never introduce petroleum-based clean-
ers, solvents, or contaminants into the washer sys-
tem. These products can rapidly deteriorate the
