release it.
If your headlamps are in the automatic position or on

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

For steady wiping at low speed, turn the band away from
you to the ®rst solid band past the delay settings. For
high-speed wiping, turn the band further, to the second
solid band past the delay settings. To stop the wipers,
move the band to off.

before using them. If they're frozen to the windshield,
carefully loosen or thaw them. If your blades do become
worn or damaged, get new blades or blade inserts.

To turn on the RainsenseŸ feature, the wipers must be
set to one of the ®ve delay settings on the multifunction
lever. Each of the ®ve settings adjusts the sensitivity
of the rainsensor. For more wipes, select the higher
settings; for fewer wipes, select the lower settings
located closer to off on the multifunction lever.
The rainsensor will automatically control the frequency
of the wipes from off to high speed according to the
weather conditions. The wipers can be left in a
rainsense mode even when it is not raining.

multifunction lever to off to avoid wiper damage
when going through an automatic car wash.

blocking your vision.
