Rain-sensing windshield wipers
When “AUTO” is selected, the wipers will operate automatically
when the sensor detects falling rain. The system automatically
adjusts wiper timing in accordance with rain volume.
When “AUTO” is selected, the sensor sensitivity can be adjusted
as follows by turning the switch ring:
Off
Rain-sensing wiper
operation (“AUTO”)
Low speed wiper
operation
High speed wiper
operation
Temporary operation

■The windshield wiper and washer can be operated when
The “ENGINE START STOP” switch is in IGNITION ON mode.
■ Effects of vehicle speed on wiper operation (vehicles with rain-sensing
windshield wipers)
Vehicle speed affects the wiper operation when the washer is being used
(delay until drip prevention wiper sweep occurs) even when the wipers are
not in “AUTO” mode.
With “ ” selected, wiper operation will be switched from low speed to
intermittent wiper operation only when the vehicle is stationary.
(However, when the sensor sensitivity is adjusted to the highest level, the
mode cannot be switched.)
■ Rain drop sensor (vehicles with rain-sensing windshield wipers)
● If the wiper switch is turned to “AUTO” position while the “ENGINE
START STOP” switch is in IGNITIO N ON mode, the wiper will operate
once to show that “AUTO” mode is activated.
● If the temperature of the rain drop sensor is 176 F (80C) or higher, or
14 F (-10 C) or lower, automatic operation may not occur. In this case,
operate the wipers in any mode other than “AUTO”.
■ If no windshield washer fluid sprays
Check that the washer nozzles are not blocked if there is washer fluid in the
windshield washer fluid reservoir.
●The sensor judges the amount of rain-
drops.

CAUTION
■
Caution regarding the use of windshield wipers in “AUTO” mode (vehi-
cles with rain-sensing windshield wipers)
The windshield wipers may operate unexpec tedly 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.
■ Caution regarding the use of washer fluid
When it is cold, do not use the washer fluid until the windshield becomes
warm. The fluid may freeze on the windshield and cause low visibility. This
may lead to an accident, resulting in death or serious injury.
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 clear 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 400 ft. (120 m) 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.
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver. The desired vehicle-to-
vehicle distance can also be set by operating the vehicle-to-vehicle dis-
tance control.
Example of deceleration cruising
When the vehicle ahead is driving slower than the set speed
When a vehicle is detected running ahead of you, the system automati-
cally decelerates your vehicle. When a greater reduction in vehicle speed
is necessary, the system applies the brakes. A warning tone warns you
when the system cannot decelerate sufficiently to prevent your vehicle
from closing in on the vehicle ahead.

■Dynamic radar cruise control can be set when
●The shift lever is in “D” or range “4” or higher of “S” has be\
en selected.
● Vehicle speed is above approximately 30 mph (50 km/h).
■ 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 25 mph (40 km/h).
● 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 high speed wiper operation position).
● When second start mode is set.
● The switching operation continues for 5 seconds or more after the center
differential lock switch has been operated.
If vehicle-to-vehicle distance control driving is automatically canceled for any
other reason, there may be a malfunction in the system. Contact your Toyota
dealer.

■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 10 mph (16 km/h)
below the set vehicle speed.
At this time, the memorized set speed is not retained.
● Actual vehicle speed falls below approximately 25 mph (40 km/h).
● VSC is activated.
● The switching operation continues for 5 seconds or more after the center
differential lock switch has been operated.
■ Radar sensor and grille cover
Always keep the sensor and grille cover clean to ensure that the vehicle-t\
o-
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 messages and bu zzers for dynamic radar cruise control
Warning messages and buzzers are used to indicate a system malfunction
or to inform the driver of the need for caution while driving. ( P. 619)

CAUTION
■When the radar 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. 220) 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 lug-
gage compartment, 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 your Toyota dealer.
● 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.
