■Automatic cancelation of c onstant speed control mode
Constant speed control mode is automatically canceled in the following situa-
tions:
● Actual vehicle speed is more than approximately 10 mph (16 km/h ) below
the set vehicle speed.
● Actual vehicle speed falls below approximately 25 mph (40 km/h) .
● VSC is activated.
● TRAC is activated for a period of time.
● When the VSC or TRAC system is turned off.
● Pre-collision braking is activated.
If constant speed control mode is automatically canceled for an y other rea-
son, there may be a malfunction in the system. Contact your Toyota dealer.
■ Brake system operation sound
If the brakes are applied automatically while the vehicle is in vehicle-to-vehi-
cle distance control mode, a brake system operation sound may b e heard.
This does not indicate a malfunction.
■ Warning messages and buzzers for d ynamic 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. If a warning message
is shown on the multi-information display, read the message and follow the
instructions.
■ When the sensor may not be correctly detect ing the vehicle ahead
In the case of the following and depending on the conditions, o perate the
brake pedal when deceleration of the system is insufficient or operate the
accelerator pedal when acceleration is required.
As the sensor may not be able to correctly detect these types o f vehicles, the
approach warning ( P. 288) may not be activated.
● Vehicles that cut in suddenly
● Vehicles traveling at low speeds
● Vehicles that are not moving in the same lane

2924-5. Using the driving support systems
●Vehicles with small rear ends (trailers with no load on board, etc.)
● Motorcycles traveling in the same lane
● When water or snow thrown up by the surrounding vehicles hinders the
detecting of the sensor
●When your vehicle is pointing upwards
(caused by a heavy load in the luggage
compartment, etc.)
● Preceding vehicle has an extremely high
ground clearance

■Conditions under which the vehic le-to-vehicle distance control mode
may not function correctly
In the case of the following conditions, operate the brake peda l (or accelera-
tor pedal, depending on the situation) as necessary.
As the sensor may not be able to correctly detect vehicles ahead, the system
may not operate properly.
● When the vehicle ahead of you decelerates suddenly
● When driving on a road surrounded by a structure, such as in a tunnel or on
a bridge
● While the vehicle speed is decreasing to the set speed after th e vehicle
accelerates by depressing the accelerator pedal
●
When the road curves or when the lanes
are narrow
● When steering wheel operation or your
position in the lane is unstable

Intuitive parking assist
■Types of sensors
■Intuitive parking assist switch
Turns the intuitive parking
assist on/off
When on, the indicator light
comes on to inform the driver
that the system is operational.
: 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 t he multi-information display
and buzzer. Always check the surrounding area when using this
system.

When the sensor detects an obstacle, the direction of and the approx-
imate distance to the o bstacle are displayed and the buzzer sou nds.

■Sensor operation and di stance to an obstacle
The system operates when the vehi cle approaches an obstacle, as
shown by the following table.
When 2 or more obstacles are detected simultaneously, the buzze r sys-
tem responds to the nearest zone.

Rear center sensor
■When multiple obstacles are de tected in front and behind the
vehicle at the same time
The buzzer will change in the following manner.
● If an obstacle has been detected within 1.5 ft. (45 cm) of the front
or 2.8 ft. (85 cm) in rear of t he vehicle (a continuous buzzer is
sounding), and a new obstacle is detected at the other end of the
vehicle, the buzzer w ill sound 7 times then 1 continuous buzzer.
● If an obstacle has been detected within 1.5 ft. (45 cm) of the front
or 2.8 ft. (85 cm) in rear of t he vehicle (a continuous buzzer is
sounding), and a new obstacle is detected in the same way at th e
other end of the vehicle, the buzzer will sound 3 times then 1
continuous buzzer.
■Detection range of the sensors
Approximately 5.9 ft. (180 cm)
Approximately 2.0 ft. (60 cm)
Approximately 2.8 ft. (85 cm)
The diagram shows the detection
range of the sensors. Note that the
sensors may not be able to detect
obstacles that are extremely close
to the vehicle.
The range of the sensors may
change depending on the shape of
the object, etc.
Approximate distance to obstacleDisplay and buzzer
5.9 ft. (180 cm) to 3.3 ft. (100 cm)Intermittent
3.3 ft. (100 cm) to 2.5 ft. (75 cm)Fast intermittent
2.5 ft. (75 cm) to 1.6 ft. (50 cm)Very fast intermittent

■The intuitive parking assist can be operated when
●Front corner sensors:
• The engine switch is in ON.
• The shift lever is in R.
• The shift lever is not in P or R and vehicle speed is less than about 6 mph
(10 km/h).
● Rear corner and rear center sensors:
• The engine switch is in ON.
• The shift lever is in R.
■ If the display flashes and a message is displayed
P. 492, 493
■ Certification (Canada only)
This ISM device complies with Canadian ICES-001.
WARNING
■When using the intuitive parking assist
Observe the following precautions.
Failure to do so may result in the vehicle being unable to be driven safely
and possibly cause an accident.
● Do not use the sensor at speeds in excess of 6 mph (10 km/h).
● The sensors’ detection areas and reaction times are limited. When moving
forward or reversing, check the areas surrounding the vehicle ( especially
the sides of the vehicle) for safety, and drive slowly, using t he brake to
control the vehicle’s speed.
● Do not install accessories within the sensors’ detection areas.

WARNING
■Sensor detection information
Pay particular attention to the following instances in where th is may occur.
Failing to do so way result in the vehicle being unable to be d riven or parked
safety and possibly cause an accident.
● The sensor’s detection areas are limited to the areas around the vehicle’s
front corner and rear bumpers.
● Certain vehicle conditions and the surrounding environment may affect the
ability of the sensor to correctly detect obstacles. Particular instances
where this may occur are listed below.
• There is dirt, snow or ice on the sensor. (Wiping the sensors will resolve
this problem.)
• The sensor is frozen. (Thawing the area will resolve this prob lem.)
• The sensor is covered in any way.
• The vehicle is leaning considerably to one side.
• On an extremely bumpy road, on an incline, on gravel, or on grass.
• The vicinity of the vehicle is noisy due to vehicle horns, mot orcycle
engines, air brakes of large vehicles, or other loud noises pro ducing
ultrasonic waves.
• There is another vehicle equipped with parking assist sensors in the
vicinity.
• The sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender pole or radio antenna.
• The bumper or sensor receives a strong impact.
• The vehicle is approaching a tall or curved curb.
• In harsh sunlight or intense cold weather.
• The area directly under the bumpers is not detected.
• If obstacles draw too close to the sensor.
• A non-genuine Toyota suspension (lowered suspension, etc.) is installed.
• A backlit license plate, license plate holder, etc., are insta lled.
• People may not be detected if they are wearing certain types a nd color-
ing of clothing.
• People, animals, and moving objects may not be able to be detected.
In addition to the examples above, there are instances in which , because of
their shape, signs and other objects may be judged by the senso r to be
closer than they are.
