To turn on the windshield wipers, move
the lever to the desired setting.
The engine switch must be in the “ON”
position.Lever position
Speed setting
Position 1Intermittent
Position 2Slow
Position 3Fast
For a single sweep of the windshield,
push the lever up and release it. With interval adjuster: The band lets you
adjust the wiping time interval when the
wiper lever is in the intermittent position
(position 1). Twist the band upward to
increase the time between sweeps, and
downward to decrease it.
To squirt washer fluid, pull the lever
toward you.
If the windshield wipers are off, they will
operate a couple of times after the washer
squirts.
For instructions on adding washer fluid,
see “Adding washer fluid” on page 539 in
Section 7
−3.
In freezing weather, warm the windshield
with the defroster before using the washer.
This will help prevent the washer fluid
from freezing on your windshield, which
can block your vision.
NOTICE
Do not operate the wipers if the wind-
shield 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 Toyota 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.

This system operates by detecting pri-
marily the reflectors of the vehicle
ahead. The distance may not be accu-
rately or absolutely detected in the fol-
lowing cases:
The vehicle ahead has higher ground
clearance, which means that the
placement of the reflectors is in a
higher position.
The rear section of the vehicle ahead
is extremely dirty.
The vehicle ahead or other vehicles
around you are flinging up water or
snow.
Excessive exhaust gas (black smoke)
is coming from the vehicle ahead or
other vehicles around you, obscuring
your front view.
There is an obstruction (protective
film, sticker, etc.) on the reflectors
on the vehicle ahead, or reflectors
are not installed on the vehicle
ahead or are damaged.
Heavy luggage in the luggage
compartment or rear seats is caus-
ing the nose of your vehicle to tilt
up.
CAUTION
To avoid accidents, always keep the
laser radar sensor glass clean and
never allow it to be covered with
icicle or any substance, so it can de-
tect the vehicle in front. (See “LASER
RADAR SENSOR” on page 235.)
CAUTION
Do not rely excessively on dynamic
laser cruise control. Observe the fol-
lowing precautions in order to avoid
serious injury or death:
Under certain conditions where the
vehicle in front slows drastically, or
is stopped, the dynamic laser cruise
control will neither warn you nor
decelerate. You must depress the
brake pedal to slow down, ensuring
collision avoidance or that suffi-
cient vehicletovehicle distance is
maintained.
Do not use dynamic laser cruise
control in the following conditions:
In bad weather (such as rain, fog,
snow, sandstorms or direct sun-
light, or when raindrops or snow-
flakes get on the laser radar sensor
glass), the vehicletovehicle dis-
tance will not be measured accura-
tely.
When using the windshield wipers
at high or low speeds the dynamic
laser radar cruise control turns off.

VEHICLETOVEHICLE DISTANCE
CONTROL MODE FAILURE WARNING
If there is trouble somewhere in the dy-
namic laser cruise control while the ve-
hicle−to −vehicle distance control mode is
on, the master warning light comes on
and the alarm sounds, and one of the
warning codes “E1”, “E2” or “E3” will ap-
pear on the display. Dynamic laser cruise
control is automatically cancelled.
If “E3” appears on the display, the
“CRUISE” indicator light in the instrument
cluster also flashes. If “E1” appears on the display,
the sys-
tem cannot easily measure the vehicle −to −
vehicle distance because of a dirty laser
radar sensor glass while the dynamic la-
ser cruise control is on.
If this code appears, clean the sensor
glass with a soft cloth and try setting the
preset speed again. If the dirt is removed
without cleaning, the system will automati-
cally enter the ready mode.
If the system does not enter the ready
mode even after cleaning or the code re-
mains on the display, the system might be
malfunctioning. Although there is no prob-
lem to continue driving, please contact
your Toyota dealer.
CAUTION
Always keep the sensor glass and
never allow it to be covered with
icicle or any substance, so it can de-
tect the vehicle in front.
If “E2” appears on the display, the sys-
tem cannot easily measure the vehicle −to −
vehicle distance because of the following
conditions:
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)
In the following cases, dynamic laser
cruise control switches to the ready mode:
The wipers are stopped or are
switched to 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 re-
stored. If the setting operation cannot be
performed or if the warning code still ap-
pears even after the weather clears, the
system might have malfuncti oned. Al-
though there is no problem to continue
driving, contact your Toyota dealer.
