For signaling turns, move the lever up or down in the
conventional manner.
The ignition key must be in the ºONº position.
The turn signal is self±cancelling after a turn, but after a
lane change, you may have to cancel it by hand. You can
also signal a lane change by moving the turn signal lever
partway and holding it there.
If the green light in the instrument cluster flashes faster
than normal, it indicates that the front or rear turn signal
bulb has burned out. If this indicator light does not come
on, the fuse or the indicator light itself has probably
failed.

To turn the wipers on, move the lever down until you
reach the desired speed setting.
The ignition key must be in the ºONº position.
There are 3 settings:

wiping time interval between sweeps, and
downward to decrease it.
The wiper lever must be in the ºINTº position.
The time interval between sweeps is shortened when
the vehicle speed increases. When the vehicle speed
reaches more than about 20 km/h (12 mph) with the
interval adjuster in ºFº position, the time interval
becomes the shortest 1.5 seconds.
If you stop the vehicle with the wiper switch in the ºLOº
position, the wiper speed automatically changes from
low speed to intermittent operation speed.* This
function does not work when the interval adjuster is in
the ºFº position.

Lexus dealer for details.
For mist wiper operation (a single wipe), pull the lever toward you and release it.
To make the washer squirt, push the button on the
end of the lever.
If the wiper lever is in the ºOFFº position, the wipers will
automatically operate a couple of times and a few
seconds later, make a single wipe again to sweep the
windshield completely.* The last sweep does not
happen if the vehicle speed exceeds about 170 km/h
(106 mph).
NOTE: *The last single wipe can be set inoperative.
