Washer/wiper dual opera-
tion
Wipers operate automati-
cally.

headlight cleaners will oper-
ate once. And then, the
headlight cleaners will oper-
ate every five times you pull
the lever. (if equipped)

Rain drop sensor (vehicles with rain-sensing windshield wipers)
Vehicles with smart entry & start system
If the wiper switch is turned to the “AUTO” position while the “ENGINE
START STOP” switch is in IGNITION ON mode, the wiper will operate
once to show that “AUTO” mode is activated.
If the wiper sensitivity is adjusted to higher, the wiper may operate once to
indicate the change of sensitivity.
Vehicles without smart entry & start system
If the wiper switch is turned to the “AUTO” position while the engine
switch is in the “ON” position, the wiper will operate once to show that
“AUTO” mode is activated.
If the wiper sensitivity is adjusted to higher, the wiper may operate once to
indicate the change of sensitivity.
If no windshield washer fluid sprays
Check that the washer nozzles are not blocked and if there is washer fluid in
the windshield washer fluid reservoir.
Windshield wiper features
The rear window and outside rear view mirror defoggers automatically turn
on when you operate the wipers.
The raindrop sensor judges the amount
of raindrops.

CAUTION
Caution regarding the use of windshield wipers in “AUTO” mode
The windshield wipers may operate unexpectedly if the sensor is touched or
the windshield is subject to vibration in “AUTO” mode. Take care that your
fingers or anything else do not become caught in the windshield wipers.
NOTICE
When the windshield is dry
Do not use the wipers, as they may damage the windshield.
When there is no washer fluid spray from the nozzle
Damage to the washer fluid pump may be caused if the lever is pulled
toward you and held continually.
When a nozzle becomes blocked
Do not try to clean it with a pin or other object. The nozzle will be damaged.

Driving in vehicle-to-vehicle distance control mode
This mode employs a radar sensor to detect the presence of vehicles
up to approximately 120 m (400 ft.) ahead, determines the current
vehicle-to-vehicle following distance, and operates to maintain a suit-
able following distance from the vehicle ahead.
Note that vehicle-to-vehicle distance will close in when traveling on long
downhill slopes.

AVENSIS_EE (OM20B44E)
Dynamic radar cruise control can be set when
The shift lever is in “D”.
Range “4” or higher of “D” has been selected by using the paddle shift.
(vehicles with paddle shift switch)
Vehicle speed is above approximately 50 km/h (30 mph).
Accelerating after setting the vehicle speed
The vehicle can accelerate normally. After acceleration, the set speed
resumes. However, during vehicle-to-vehicle distance control mode, the
vehicle speed may decrease below the set speed in order to maintain the
distance to the vehicle ahead.
Automatic cancelation of vehicle-to-vehicle distance control
Vehicle-to-vehicle distance control driving is automatically canceled in the
following situations:
Actual vehicle speed falls below approximately 40 km/h (25 mph).
VSC is activated.
The sensor cannot operate correctly because it is covered in some way.
The windshield wipers are operating at high speed (when the wiper
switch is set to the “AUTO” mode or the high speed wiper operation posi-
tion).
If vehicle-to-vehicle distance control driving is automatically canceled for any
other reason, there may be a malfunction in the system. Contact any autho-
rized Toyota dealer or repairer, or another duly qualified and equipped pro-
fessional.

Automatic cancelation of constant speed control
The cruise control will stop maintaining the vehicle speed in the following sit-
uations:
Actual vehicle speed is more than approximately 16 km/h (10 mph)
below the set vehicle speed.
At this time, the memorized set speed is not retained.
Actual vehicle speed falls below approximately 40 km/h (25 mph).
VSC is activated.
Speed limiter is activated. (if equipped)
Radar sensor and grille cover
Always keep the sensor and grille cover clean to ensure that the vehicle-to-
vehicle distance control operates properly. (Some obstructions, such as
snow, ice and plastic objects, cannot be detected by the obstruction sensor.)
Dynamic radar cruise control is canceled if an obstruction is detected.
Warning lights, messages and buzzers for dynamic radar cruise con-
trol
Warning lights, messages and buzzers are used to indicate a system mal-
function or to inform the driver of the need for caution while driving.

CAUTION
When the sensor may not be correctly detecting the vehicle ahead
Apply the brakes as necessary when any of the following types of vehicles
are in front of you.
As the sensor may not be able to correctly detect these types of vehicles,
the approach warning (P. 289) will not be activated, and a fatal or serious
accident may result.
Vehicles that cut in suddenly
Vehicles traveling at low speeds
Vehicles that are not moving
Vehicles with small rear ends (trailers with no load on board etc.)
Motorcycles traveling in the same lane
Conditions under which the vehicle-to-vehicle distance control may
not function correctly
Apply the brakes as necessary in the following conditions as the radar sen-
sor may not be able to correctly detect vehicles ahead, and a fatal or serious
accident may result:
When water or snow thrown up by the surrounding vehicles hinders the
functioning of the sensor
When your vehicle is pointing upwards (caused by a heavy load in the
trunk etc.)
When the road curves or when the lanes are narrow
When steering wheel operation or your position in the lane is unstable
When the vehicle ahead of you decelerates suddenly

CAUTION
Handling the radar sensor
Observe the following to ensure the cruise control system can function effec-
tively.
Otherwise, the system may not function correctly and could result in an acci-
dent.
Keep the sensor and grille cover clean at all times.
Clean the sensor and grille cover with a soft cloth so you do not mark or
damage them.
Do not subject the sensor or surrounding area to a strong impact.
If the sensor moves even slightly off position, the system may malfunction.
If the sensor or surrounding area is subject to a strong impact, always
have the area inspected and adjusted by any authorized Toyota dealer or
repairer, or another duly qualified and equipped professional.
Do not disassemble the sensor.
Do not attach accessories or stickers to the sensor, grille cover or sur-
rounding area.
Do not modify or paint the sensor and grille cover.
Do not replace them with non-genuine parts.
