5. WIPER AND WASHER SWITCH

SWITCHES
53
FOG LIGHT SWITCH
To turn on the fog lights, twist the band of the headlight
switch lever to the position of the fog light. The fog lights
come on only when the headlights are on low beam.
WINDSHIELD WIPER AND WASHER SWITCH
Variable intermittent windshield wipers
1Interval adjuster
2Washer 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 — Variable intermittent operation
“LO” position — Low speed operation
“HI” position — High speed operation

SWITCHES
54Twist 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.
For mist wiper operations (a single wipe), pull the lever up
and release it.
To make the washer squirt, pull the lever toward you and
release it.
Also, the wipers will automatically operate a couple of times
after the washer squirts even with the lever in the “OFF”
position.
Vehicles with headlight cleaner — If you pull the windshield
washer lever toward you with the headlights on, the headlight
cleaner operates once automatically together with the
windshield washer fluid.
The 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 609. 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.
When
waxing your vehicle, make sure that the washer nozzles
do not become blocked. If a nozzle becomes blocked, contact
your Lexus dealer to have the vehicle serviced.
NOTICE
If a nozzle becomes blocked, do not try to clear it with
a pin or other object. The nozzle will be damaged.

Rainsensing windshield wipers
1Automatic control adjuster
2Washer 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:
“AUTO” position — Automatic operation
“LO” position — Low speed operation
“HI” position — High speed operation Automatic operation
The wiper speed is determined by the amount of raindrops
and sunlight detected by the automatic wiper control
sensor.
You may adjust the automatic wiper control sensitivity by
twisting the automatic control adjuster in the “”
direction, which requires more raindrop volume to start
the wiper, or in the “+” direction, which requires less
raindrop volume to start the wiper.
The sensor is on the inside of the windshield as shown above.

SWITCHES
56Even if the wiper lever is in the
“AUTO” position, the system will
switch to variable intermittent operations in the following
conditions:
 When the windshield gets extremely cold (at less than
–10 C [14 F])
 When the system malfunctions
However, when the windshield gets extremely hot (at more
than 90 C [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.

STARTING AND DRIVING
421
CAUTION
Do not rely excessively on dynamic laser cruise control.
Observe the following precautions in order to avoid
serious injury or death:
 Under certain conditions when the vehicle in front
slows abruptly, or is stopped, the dynamic laser
cruise control may be unable to decelerate
automatically or to warn you. You must apply the
brakes manually in order to maintain a safe
vehicletovehicle distance or avoid collision.
Therefore, pay careful attention to following
distance, even when using the dynamic laser cruise
control.
 Do not use dynamic laser cruise control in the
following conditions:
In bad weather (such as rain, fog, snow, sandstorms
or direct sunlight, or when raindrops or snowflakes
get on the laser radar sensor glass), the
vehicletovehicle distance will not be measured
accurately.
When using the windshield wipers at high or low
speeds, the dynamic laser cruise control turns off.
On roads with heavy traffic or sharp bends, an
appropriate speed cannot be maintained and an
accident may occur.
On slippery road surfaces (icy or snowcovered road
surfaces), the tires will race and you will be unable to
control the vehicle.
When there is no vehicle detected ahead on steep
downhill slopes, the preset speed will be easily
exceeded because of inefficient engine braking. (In
this case, automatic braking will not work.) If there is
a vehicle detected ahead, the delay in deceleration
timing could cause serious injury or death.
When the alarm sounds frequently (because of
frequent changes of speed or insufficient
vehicletovehicle distance), this indicates that the
system cannot maintain an appropriate
vehicletovehicle distance and an accident may
occur.
On roads with steep and short inclines and declines,
failure to detect the vehicle ahead will shorten the
distance between your vehicle and the vehicle ahead
and an accident may occur.

STARTING AND DRIVING
432If “E2” appears on the display,
the system may be having
trouble measuring the vehicle −to− vehicle distance because of
any of the following:
 The wipers are operating at high or low speeds
 Direct sunlight from the front
 It is difficult to make a measurement because of bad
weather (such as rainy, foggy, or snowy weather)
 Driving in “SNOW” mode
In the following cases, dynamic laser cruise control switches
to the ready mode:
 The wipers are stopped or are switched to variable
intermittent operation.
 No direct sunlight from the front
In the above conditions, push the lever up in the “+ RES”
direction and release it. Dynamic laser cruise control will be
restored. If the setting operation cannot be performed or if the
same code still appears even after the weather clears, the
system might have malfunctioned. Although there is no
problem to continue driving, please contact your Lexus dealer. If “E3” appears on the display,
a system malfunction has
been detected.
If this warning code appears, stop your vehicle in a safe place,
turn the ignition off, and then restart it to reset the system. If
the same code appears again or if the cruise control cannot be
set, the system may be malfunctioning. Although there is no
problem to continue driving, please contact your Lexus dealer.
