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

time interval between sweeps, and downward to decrease
it.

SWITCHES

The wiper lever must be in the “INT” position.
The time interval between sw
eeps is shortened when the
vehicle speed increases. When the vehicle speed reaches
more than about 20 km/h (12 mph) with the interval adjuster
twisted down to the lowest position, the time interval becomes
the shortest 1.5 seconds.
If you stop the vehicle with the wiper switch in the “LO” position,
the wiper speed automatically changes from low speed to
intermittent operation speed.* This function does not work with
the interval adjuster twisted down to the lowest position.
NOTE:
* This feature can be deactivated.
Ask your Lexus dealer for details.
For mist wiper operations (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 “OFF” position, the wipers will
automatically make 3 wipes and then a single wipe later to
sweep the windshield completely.* The interval between the
3 wipes and the last wipe will depend on the vehicle speed.
The last sweep does not happen if the vehicle speed exceeds
about 170 km/h (106 mph). NOTE:
* The last single wipe can be deactivated.
Ask your Lexus dealer for details. The warning message “Low Washer Fluid” is displayed in the
multi−
information display when the fluid level in the tank
becomes very low. For information on adding washer fluid, see
“Adding washer fluid” on page 503.
When the headlights are on and the washers are activated by
pushing the windshield washer switch, the headlight cleaner
operates once automatically.
In cold weather, warm the windshield with the defroster before
using the washer. This will help prevent icing, which could
block your vision.
The rear window and outside rear view mirror defogger

Do not operate the wipers if the windshield is dry. It may
scratch the glass.
