WARNING
■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 etc. 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 the washer fluid tank is empty
Do not operate the switch continually as the washer fluid pump may over-
heat.
■ 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.

Driving
Pulling the lever toward you
cancels the cruise control.
The speed setting is also canceled
when the brakes are applied.
Pushing the lever up resumes
the cruise control and returns
vehicle speed to the set speed.
Resuming is available when the vehicle speed is more than approximately
25 mph (40 km/h).
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 fr om 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.

■Dynamic radar cruise control can be set when
●The shift lever is in the D or the range 4, 5 or 6 of S has been 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 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 wiper switch is
set to the “AUTO” mode or the high speed wiper operation position).
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
■Situations unsuitable for dynamic radar cruise control
Do not use dynamic radar cruise control in any of the following situations.
Doing so may result in inappropriate speed control and could cause an acci-
dent resulting in death or serious injury.
●In heavy traffic
● On roads with sharp bends
● On winding roads
● On slippery roads, such as those covered with rain, ice or snow
● On steep downhills, or where there are sudden changes between sharp up
and down gradients
Vehicle speed may exceed the set speed when driving down a steep hill.
● At entrances to expressways
● When weather conditions are bad enough that they may prevent the sen-
sors from functioning correctly (fog, snow, sandstorm, heavy rain, etc.)
● When an approach warning buzzer is heard often
● When your vehicle is towing a trailer
■ When the sensor may not be correct ly 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. 268) 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

WARNING
■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 seri-
ous 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
■ Handling the radar sensor
Observe the following to ensure the cruise control system can function
effectively:
Otherwise, the system may not function correctly and could result in an
accident.
●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 a 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.
● If the sensor needs to be replaced, contact your Toyota dealer.

: If equipped
The distance from your vehicle to nearby obstacles when paral-
lel parking or maneuvering into a garage is measured by the
sensors and communicated via the multi-information display,
the audio system screen and a buzzer. Always check the sur-
rounding area when using this system.

■Buzzer operation and distance to an obstacle
A buzzer sounds when the sensors are operating.
●The buzzer sounds faster as the vehicle approaches an obstacle.
When the vehicle comes within the following distance of the
obstacle, the buzzer sounds continuously.
• Front and rear corner sensors: Approximately 0.8 ft. (25 cm)
• Rear center sensors: Approximately 1.1 ft. (35 cm)
● When 2 or more obstacles are detected simultaneously, the
buzzer system responds to the nearest obstacle. If one or both
come within the above distance s, the beep will repeat a long
tone, followed by fast beeps.
Approximately 2.0 ft. (60 cm)
Approximately 2.8 ft. (85 cm)
Approximately 5.9 ft. (180 cm)
The diagram shows the detection
range of the sensors. Note that the
sensors cannot detect obstacles
that are extremely close to the
vehicle.
The range of the sensors may
change depending on the shape of
the object etc.
