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.

52The 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 589.
In cold weather, warm the windshield with the defroster before
using the washer. This will help prevent icing, which could
block your vision.
NOTICE
Do not operate the wipers if the windshield is dry. It may
scratch the glass.

Radar Cruise Control Warning
G13073
If the system cannot easily measure the
vehicletovehicle distance because of a dirty millimeter
wave radar sensor or grille cover while the dynamic radar
cruise control is on, the master warning light comes on
and the “CRUISE” indicator light flashes. At this time a
warning tone sounds and the above message appears.
If this message appears, clean the sensor and grille cover with
a soft cloth and try setting the preset speed again. If the dirt
is removed without cleaning, the system will automatically
enter the “RADAR READY” mode. If the system does not enter
the “RADAR READY” mode even after cleaning or the
message remains on the display, the system might be
malfunctioning. Although it is no problem to continue driving,
contact your Lexus dealer.
G13074
If the system cannot easily measure the
vehicletovehicle distance because of the following
conditions while the dynamic radar cruise control is on,
the master warning light comes on, the “CRUISE”
indicator light flashes. At this time a warning tone sounds
and the above message appears.
 The driving pattern selector switch is set to the snow
position mode.
 It is determined that it is difficult to make a measurement
because of bad weather (such as extremely hot weather)
 The wipers are operated at high speed with the wiper lever
in the “AUTO” position
In the following cases, the dynamic radar cruise control
switches to the “RADAR READY” mode:
 The driving pattern selector switch is changed to the normal
or power position.
 The wipers are stopped or are switched to low speed or
intermittent operation. (Including intermittent and stopped
wipers in the “AUTO” position)

STARTING AND DRIVING
405
CAUTION
Certain conditions make vehicle detection difficult or
impossible.
As this system operates by detecting primarily the
reflected wave from the rear end of the vehicle ahead,
the distance cannot be accurately detected in the
following cases, resulting in improper
vehicletovehicle distance.
♦ The rear section of the vehicle ahead is extremely
small such as an unloaded trailer.
♦ The vehicle ahead or other vehicles around you
are flinging up water or snow.
♦ Heavy luggage which is loaded in your trunk or on
top of your rear seats is raising up the nose of your
vehicle.
 The millimeter wave radar sensor automatically
detects dirt if it is sticking to the front of the sensor
or cover of your vehicle, and if detected, a message
appears on the multiinformation display. However,
if the sensor or cover is covered with a metallic vinyl
bag, icicle, snowflakes, etc., dirt may not be detected,
resulting in improper vehicletovehicle distance.
Continue driving with due care to the vehicle ahead.
If dirt is detected, the dynamic radar cruise control
function is automatically cancelled. Always keep the
sensor and cover clean.
Dynamic radar cruise control should not be used in the
following conditions, to avoid death or serious injury.
 In bad weather (such as rain, fog, snow , sandstorms,
or when raindrops or snowflakes get in the millimeter
wave radar sensor or the cover), the
vehicletovehicle distance will not be measured
accurately.
If the wipers are operated at high speed (including the
high speed operation with the wiper lever in the
“AUTO” position), dynamic radar cruise control is
automatically cancelled. (In the case of the low speed
operation and intermittent wiper operation, it is not
cancelled.) Dynamic radar cruise control is
automatically cancelled when the measurement is
extremely unstable due to bad weather.
 On the roads in heavy traffic or at sharp bends:
As an appropriate speed cannot be maintained, death
or serious injury could result.
 On slippery road surfaces (icy or snowcovered road
surfaces):
The tires will race and you will be unable to control.
