Jeep 2013 Wrangler - Manual (Page 176)

Windshield Wiper Operation
Rotate the end of the lever upward to the second detent
past the intermittent settings for low-speed wiper opera-
tion. Rotate the end of the lever upward to the third
detent past the intermittent settings for high-speed wiper
operation.
CAUTION!
In cold weather, always turn off the wiper switch and
allow the wipers to return to the park position before
turning off the engine. If the wiper switch is left on
and the wipers freeze to the windshield, damage to
the wiper motor may occur when the vehicle is
restarted.
Intermittent Wiper System
Use the intermittent wiper when weather conditions make
a single wiping cycle, with a variable pause between cycles,
desirable. Rotate the end of the lever to the first detent
position for one of five intermittent settings. The delay cycle
can be set anywhere between 1 to 18 seconds.
