Jeep grand cherokee 2018, Owner'S Manual, Page: 82 / 620

If the end of the lever is pushed while the wipers are in the
off position, the wipers will operate for several wipe cycles,
then turn off.
WARNING!
Sudden loss of visibility through the windshield could
lead to a collision. You might not see other vehicles or
other obstacles. To avoid sudden icing of the wind-
shield during freezing weather, warm the windshield
with the defroster before and during windshield
washer use.
Mist
Use the Mist feature when weather conditions make occa-
sional usage of the wipers necessary. Rotate the end of the
lever downward to the MIST position and release for a
single wiping cycle.
NOTE:
The Mist feature does not activate the washer
pump; therefore, no washer fluid will be sprayed on the
windshield. The wash function must be used in order to
spray the windshield with washer fluid.
Rain Sensing Wipers — If Equipped
This feature senses rain or snowfall on the windshield and
automatically activates the wipers for the driver. The
feature is especially useful for road splash or overspray
from the windshield washers of the vehicle ahead. Rotate
the end of the multifunction lever to one of four settings to
activate this feature.
