Windshield Washer - GMC 2008 Yukon Denali Owner's Manual

To turn on the Rainsense™ feature, the wipers must
be set to one of the five delay settings. Each of the
five settings adjusts the sensitivity of the rain sensor.
Since different drivers have different setting preferences,
it is recommended that the mid-range setting, position
three, be used initially. For more wipes, select the higher
settings; for fewer wipes, select the lower settings located
closer to the off position on the multifunction lever.
The rain sensor 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.
When Rainsense™ II is active, the headlamps will turn
on automatically after approximately eight wipes.
The headlamps will turn off if the wiper switch is set to a
delay position, and there have been no wipes for
approximately three minutes, or if the wiper switch is
turned to the off position. If it is dark outside, the
headlamps will remain on.
Notice: Going through an automatic car wash with
the wipers on can damage them. Turn the wipers
off when going through an automatic car wash.
