The windshield wiper and washer can be operated when
Vehicles with smart key system
The “ENGINE START STOP” switch is in IGNITION ON mode. Vehicles without smart key system
The engine switch is in the “ON” position.
■ Dripping prevention wiper sweep
After washing and wiping operation several times, the wipers operate one
more time after a short delay to prevent dripping.
However, the last sweep will not happen if the vehicle is traveling above 106
mph (170 km/h).
■ Effects of vehicle speed on wiper operation
Vehicle speed affects the following even when the wipers are not in “AUTO”
mode.
● Intermittent wiper interval ( mode)
● Wiper operation when the washer is being used (delay until drip preven-
tion wiper sweep occurs)
With low speed mode, wiper operation will be switched from low speed to
intermittent wiper operation only when the vehicle is stationary.
■ Rain drop sensor (vehicles equipped with the raindrop detection wind-
shield wipers)
The sensor judges the amount of rain-
drops.

■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.
■ In extremely hot or cold weather (v ehicles equipped with the raindrop
detection windshield wipers)
Even if the wiper lever is in “AUTO” mode, the system will switch to intermit-
tent operations when the system malfunctions.
However, when the windshield gets extremely hot (at more than 194°F
[90°C]) or extremely cold (at less than 14°F [-10°C]), the wipers do not oper-
ate even if the wiper lever is in “AUTO” mode.
■ Customization that can be co nfigured at Toyota dealer
Settings (e.g. drip prevention function) can be changed.
(Customizable features P. 457)
CAUTION
■Caution regarding the use of windshield wipers in “AUTO” mode
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.
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.

Cruising in vehicle-to-veh icle distance control mode
This mode employs a laser radar sensor to detect the presence of
vehicles within 400 ft. (120 m) ahead and to judge the distance
between your vehicle and those vehicles.
Note that vehicle-to-vehicle distance will close 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 switch.
Example of deceleration cruising
When the vehicle ahead is driving slower than the set speed
When a vehicle is detected running ahead of you, in the same lane, the
system automatically 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 on the vehicle ahead.

■Dynamic laser cruise control warning lights, display and buzzers
Warning lights, display and buzzers are used to indicate a system malfunc-
tion or to alert you to the need for caution while driving.
The warning codes indicate the following.
If the same code appears again after implementing the correction procedure,
or if the cruise control cannot be set, contact your Toyota dealer.

■Switching modes
The mode cannot be switched to constant speed control mode if vehicle-to-
vehicle distance control mode has been used. The mode also cannot be
switched from constant speed control to vehicle-to-vehicle control mode.
Turn the system off by pressing the “ON-OFF” button, and turn it on again.
■ The dynamic laser cruise can be set when
● The shift lever is in “D” or the “4”, “5” or “6” range of “S” mode.
● Vehicle speed is between approximately 28 mph (45 km/h) and 85 mph
(135 km/h).
■ Accelerating
The vehicle can be accelerated normally.
■ Automatically canceling vehicle-to-vehicle distance control
Vehicle-to-vehicle distance control driving is automatically canceled in the
following situations.
● Vehicle speed falls below 25 mph (40 km/h)
● VSC is activated
● The sensor cannot operate correctly because it is covered in some way
Vehicle-to-vehicle distance control driving must be reset by turning the “ON-
OFF” button on again.
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.
■ Automatically canceling constant speed control
The set speed is automatically canceled in the following situations.
● Actual vehicle speed is more than 10 mph (16 km/h) below the preset
vehicle speed
At this time, the memorized set speed is not retained.
● Vehicle speed falls below 25 mph (40 km/h)
● VSC is activated

■Vehicle-to-vehicle distance settings
Select a distance from the table below. Note that the distances shown corre-
spond to a vehicle speed of 55 mph (90 km/h). Vehicle-to-vehicle distance
increases/decreases in accordance with vehicle speed.
■ Laser radar sensor
■ Approach warning
In the following instances, there is a possibility that the warning will not
occur.
● When the speed of the vehicle ahead matches or exceeds your vehicle’s
speed
● When the vehicle ahead is traveling at an extremely slow speed
● Immediately after the cruise control speed has been set
● At the instant the accelerator is applied
■ Certification
Distance optionsVehicle-to-vehicle distance
Long Approximately 245 ft. (75 m)
Medium Approximately 165 ft. (50 m) Short Approximately 100 ft. (30 m)
Always keep the sensor clean to ensure
that the vehicle-to-vehicle distance con-
trol operates properly. (Some obstruc-
tions, such as snow, ice or plastic objects,
cannot be detected by the obstruction
sensor.)
Dynamic laser cruise control is canceled
if an obstruction is detected.

CAUTION
■When the laser 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 proximity alarm ( P. 175) will not be activated, and an 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 laser radar
sensor may not be able to correctly detect vehicles ahead, and an 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.
