A
CAUTION:
Driving without washer fluid can be
dangerous. A bad mud splash can block
your vision. You could hit another vehicle
or go off the road. Check your washer
fluid level often.
In freezing weather,
don't
use your washer
until the windshield is warmed. Otherwise
the washer fluid can form ice on the
windshield, blocking your vision.
