tions; for continuous operation advance to the 3rd and

ing on how long you hold the switch in) the wipers will
shut off automatically.
The windshield washer tank is located inside the engine
compartment below the radiator expansion tank. See
“

washing fluid level weekly. If necessary, fill to top.
CAUTION: If the electric pump is operated for a
long period (more than 15 seconds) with a dry
reservoir, the pump rotor may be damaged.
