Variable intermittent wipers
G12007
1Interval adjuster 2Washer on
To turn the wipers on, move the lever down until you reach
the desired speed setting.
The engine switch must be selected in “IG −ON” mode.
There are 3 settings:
”INT” position: Intermittent operation
”LO” position: Low speed operation
”HI” position: High speed operation
Twist the interval adjuster upward to increase the wiping
time interval between sweeps, and downward to decrease
it. 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 up
and release it.
To make the washer squirt, push the lever toward you and
release it.
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:
*This function can be changed as follows: The time before the last single wipe can be set for
about 3 seconds.
The last single wipe can be deactivated.
Ask your Lexus dealer for details.

using the washer. This will help prevent icing, which could
block your vision.
