In the situations below, the system may not be able to correctly detect the
surrounding brightness levels, and may flash or expose nearby pedestrians
to the high beam. Therefore, you should consider turning the high beams on
or off manually rather than relying on the Automatic High Beam system.
• In bad weather (rain, snow, fog, sandstorms etc.)
• The windshield is obscured by fog, mist, ice, dirt etc.
• The windshield is cracked or damaged.
• The inside rear view mirror or ca mera sensor is deformed or dirty.
• Surrounding brightness levels are equal to those of headlights, tail lights or fog lights.
• Vehicles ahead have headlights that are either switched off, dirty, are changing color, or have are not aimed properly.
• When driving through an area of in termittently changing brightness and
darkness.
• When frequently and repeatedly driving ascending/descending roads, or roads with rough, bumpy or uneven surfaces (such as stone-paved
roads, gravel tracks etc.).
• When frequently and repeatedly taking curves or driving on a winding road.
• There is a highly reflective object ahead of the vehicle, such as a sign or a mirror.
• The vehicle’s headlights are damaged or dirty.
• The vehicle is listing or tilting, due to a flat tire etc.
• The driver believes that the high beam may be causing problems or dis- tress to other drivers or pedestrians nearby.
■ If the Automatic High Beam indicator flashes
It may indicate a malfunction in the system. Contact your Toyota dealer.
■ Customization
The automatic high beam can be deactivated.
(Customizable feature: P. 455)
CAUTION
■Limitations of the Automatic High Beam
Do not rely on the Automatic High Beam. Always drive safely, taking care to
observe your surroundings and turning high beam on or off manually if nec-
essary.

■The windshield wiper and washer can be operated when
The engine switch is in IGNITION ON mode.
■ Effects of vehicle speed on wiper operation (vehicles with rain-sensing
windshield wipers)
With low speed windshield wiper operat ion selected, wiper operation will be
switched from low speed to intermittent wiper operation only when the vehicle
is stationary.
■ Raindrop sensor (vehicles with ra in-sensing windshield wipers)
● If the wiper is turned to AUTO mode while the engine switch is in IGNITION
ON mode, the wipers will operate once to show that AUTO mode is acti-
vated.
● If the temperature of the raindrop sensor is 194°F (90°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 mode.
■ 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 raindrop sensor judges the amount
of raindrops.
An optical sensor is adopted. It may not
operate properly when sunlight from the
rising or setting of the sun intermittently
strikes the windshield, or if bugs etc. are
present on the windshield.

CAUTION
■Caution regarding the use of windsh ield wipers in AUTO mode (vehi-
cles with rain-sensing windshield wipers)
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 fin-
gers 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
In this case, contact your Toyota dealer.
Do not try to clear it with a pin or other object. The nozzle will be damaged\

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 drivi ng slower than the set speed
When a vehicle is detected running ahead of you, 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 clos-
ing 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 been selected.
● Range 4 or higher of D has been selected by using the paddle shift.
● 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 vehi-
cle speed may decrease below the set speed in order to maintain the dis-
tance to the vehicle ahead.
■ Automatic cancelation of vehic le-to-vehicle distance control
Vehicle-to-vehicle distance control driving is automatically canceled in the fol-
lowing 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 wipers are in
AUTO mode [rain-sensing windshield wipers] or the high speed wiper oper-
ation).
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 situ-
ations:
● 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.
● Vehicle speed falls below approximately 25 mph (40 km/h).
● VSC is activated.
■ 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 messages and buzzers 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. The following actions
may solve the problem.
●When a message indicating to perform system check is displayed:
Press the “ON-OFF” button once to deactivate the system, and then press
the button again to reactivate the system.
● When a message indicating to clean the radar sensor is displayed:
Dirt, ice, etc. is on the radar sensor surface. Clean the sensor.
● When a message indicating that the cruise control is not available is dis-
played:
If the wipers are operating at high speed (including when the wiper switch is
in the AUTO position), the radar cruise control is not available. Use the
cruise control when it is possible to drive without operating the wipers at
high speed.
If the warning message remains on even after the above actions have been
performed, the system may be malfunctioning. Have the vehicle inspected by
your Toyota dealer. Grille cover
