Windshield Washer
When the lever is pulled to activate the windshield washer, the
wipers operate for about three cycles after the spray stops.
Washing the windshield
Do not try to clean the windshield when the washer fluid
container is empty or activate the washers at any time for more
than 15 seconds continuously. This could damage the washer
pump system.
Always warm up the windshield with the defroster
before you use the washer fluid. In freezing weather, the
washer solution may freeze on the windshield and
obscure your vision.
For information about refilling the washer fluid or replacing
your windshield wiper blades, see Windshield washer fluid and
Wipers in the Index.
