Check the f luid level in the
windshield washer reservoir at least
monthly during normal use.Check the f luid level with the engine
at normal operating temperature.
Fill the reservoir with a good-quality
windshield washer f luid. This
increases the cleaning capability and
prevents f reezing in cold weather.
When you ref ill the reservoir, clean
the edges of the windshield wiper
blades with windshield washer f luid
on a clean cloth. This will help to
condition them. If the washer f luid is low, a
‘‘WASHER FLUID LOW’’ message

The f luid should be between the
UPPER LEVEL and LOWER LEVEL.
If not, add power steering fluid to the

The f luid level should be between
theMINandMAXmarksontheside
of the reservoir. If the level is at or
below the MIN mark, your brake
system needs attention. Have the
