Driver Controls; Windshield Wiper/Washer Control - Ford F-150 2010 Owner's Manual

Driver Controls

MULTI-FUNCTION LEVER
Windshield wiper: Rotate the end
of the control away from you to
increase the speed of the wipers;
rotate towards you to decrease the
speed of the wipers.
Rain sensing wipers (if equipped): The rain sensing wipers will
automatically activate when moisture is present on the windshield and
the multi-function switch is set to one of five auto/interval moisture
sensitivity settings. Rotate the end of the control toward the windshield
to increase the sensitivity. The speed of the rain sensitive wipers will
vary based on the amount of moisture detected on the windshield and
the auto/interval setting. There are no interval (intermittent wipe)
settings on vehicles with rain sensing wipers. The wipers will continue to
wipe as long as the presence of moisture is detected on the windshield.
More or less wiping may occur depending on humidity, mist or light rain,
or road spray.
Keep the outside of the windshield clean, especially the area around the
rear view mirror where the sensor is located or rain sensor performance
may be affected.
Note: During winter driving conditions with ice, snow or a salty road
mist, inconsistent or unexpected wiping or smearing may occur. In these
conditions, you can lower the sensitivity to reduce the amount of
smearing or override the feature by selecting low- or high-speed wiping
or turning the wiper system off.
Note: The rain sensing wiper feature must be turned off before entering
a car wash.
