WINDSHIELD WIPER AND WASHERSWITCH
Intermittent operation type
 1 Interval adjuster

2 Washer on
To turn the wipers on, move the lever down until you reach
the desired speed setting.
The ignition key must be in the “ON” position.
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 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
the full upward 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
when the interval adjuster is in the full upward position.
NOTE:
*This feature can be deactivated.
Ask your Lexus dealer for details.
To make the washer squirt, pull 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:
*The last single wipe can be deactivated.
Ask your Lexus dealer for details.

28The low washer fluid warning light in the instrument cluster
comes on when the fluid level in the tank becomes nearly
empty. For information on adding washer fluid, see “Adding
washer fluid” on page 454.
In cold weather, warm the windshield with the defroster before
using the washer. This will help prevent icing, which could
block your vision.

scratch the glass.

Even if the wiper lever is in the
“AUTO” position, the system will
switch to intermittent operations in the following conditions:
 When the windshield gets extremely cold (at less than
–10 C or 14 F)
 When the system malfunctions
However, when the windshield gets extremely hot (at more
than 90C or 194F), the wipers do not operate even if the
wiper lever is in the “AUTO” position.
When the ignition switch is turned off with the wiper lever in the
“AUTO” position, and then the ignition switch is turned on
again, the automatic operation may not work even if raindrops
are on the windshield.
In this case, move the lever to another position and return it to
the “AUTO” position again.
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
when the automatic control adjuster is in the “+” position.
NOTE:
*This feature can be deactivated.
Ask your Lexus dealer for details.
CAUTION
Be careful not to get your fingers caught between the
wipers and windshield.
When the wiper lever is in the “AUTO” position with the
ignition switch on, the wipers could operate
automatically in the following cases:
 If you touch the upper center of the windshield
adjacent to the sensor.
 If you wipe the upper center of the windshield
(adjacent to which the sensor is located) with a towel.
 If the windshield vibrates.
 If you touch the sensor.
NOTICE
Do not apply detergent to or wet the automatic wiper
control sensor when cleaning the inside of the
windshield.
