WARNING
Do not use the washers in freezing weather
without first warming the windshield with the
defrosters; otherwise, the washer solution may
freeze on the windshield and obscure your vision
and cause an accident which could result in
property damage, personal injury, or death.
Do not use radiator coolant or anti-freeze in the
windshield washer reservoir.
Radiator coolant
in the washer reservoir can severely reduce
visibility when sprayed on the windshield.
Keep the fluid reservoir filled with Fleetrite® Windshield Washer
Solvent or equivalent.
