Jeep Grand Cherokee 2020 Owner's Manual page 57

CAUTION!
Always remove any buildup of snow that
prevents the windshield wiper blades from
returning to the "park" position. If the
windshield wiper switch is turned off, and the
blades cannot return to the "park" position,
damage to the wiper motor may occur.
Intermittent Wiper System
Use one of the four intermittent wiper settings
when weather conditions make a single wiping
cycle, with a variable delay between cycles,
desirable. At driving speeds above 10 mph
(16 km/h), the delay can be regulated from a
maximum of approximately 18 seconds
between cycles (first detent), to a cycle every
one second (fourth detent).
Intermittent Wiper Operation
NOTE:
If the vehicle is moving less than 10 mph
(16 km/h), delay times will be doubled.
Windshield Washer Operation
To use the washer, push on the end of the lever
(toward the steering wheel) and hold while
spray is desired. If the lever is pushed while in
the intermittent setting, the wipers will turn on
and operate for several wipe cycles after the
end of the lever is released, and then resume
the intermittent interval previously selected.
GETTING TO KNOW YOUR VEHICLE
Windshield Washer Operation
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.
NOTE:
As a protective measure, the pump will stop if
the switch is held for more than 20 seconds.
Once the switch is released the pump will
resume normal operation.
