You can set
the wiper speed for a long or short delay
between wipes. This can be very useful in light rain
or
snow. Turn the band to choose the delay time. The
closer to "LO," the shorter the delay.
For steady wiping at low speed, turn the band away
from you to the "LO" position. For high speed wiping,
turn the band further, to "HI."
To
stop the wipers, move
the band to "OFF."
Remember that damaged wiper blades may prevent you
from seeing well enough to drive safely. To avoid
damage, be sure to clear ice and snow from the wiper
blades before using them. If they're frozen to the
windshield, carefully loosen or thaw them. If your
blades do become damaged, get new blades or blade
inserts.
Heavy snow or ice can overload your wiper motor. A
circuit breaker will stop the motor until it cools. Clear
away snow or ice to prevent an overload.
Windshield Washer
At the top of the turn signalheadlight beam lever there's
a paddle with the word "PUSH" on it. To spray washer
fluid on the windshield, push the paddle.
If you push the paddle less than one second, washer
fluid will spray three to four times while the wiper
blades cycle. If you push the paddle longer than one
second, washer fluid will spray as long
as
the paddle is
held. When you release the paddle, the wiper blades will
cycle three to four more times to clear the window and
then either stop or return
to
your preset speed.
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.
