1Pressing the cancel switch can-
cels the speed control.
The speed control is also canceled
when the brake pedal is depressed.
(When the vehicle has been stopped by
system control, depressing the brake
pedal does not cancel the setting.)
2 Pressing the “+RES” switch
resumes the cruise control and
returns vehicle speed to the set
speed.
When your vehicle is too close to a
vehicle ahead, and sufficient auto-
matic deceleration via the cruise
control is not possible, the display
will flash and the buzzer will sound
to alert the driver. An example of
this would be if another driver cuts
in front of you while you are follow-
ing a vehicle. Depress the brake
pedal to ensure an appropriate
vehicle-to-vehicle distance.
■Warnings may not occur when
In the following instances, warnings
may not occur even when the vehi-
cle-to-vehicle distance is small.
 When the speed of the preceding
vehicle matches or exceeds your
vehicle speed
 When the preceding vehicle is
traveling at an extremely slow
speed
 Immediately after the cruise con-
trol speed was set
 When depressing the accelerator
pedal
When constant speed control mode
is selected, your vehicle will main-
tain a set speed without controlling
the vehicle-to-vehicle distance.
Select this mode only when vehi-
cle-to-vehicle distance control
mode does not function correctly
due to a dirty radar, etc.

Dynamic Radar Cruise Control with
Road Sign Assist can be
enabled/disabled in on the
multi-information display. ( P.431)
When the Dynamic Radar Cruise
Control with Road Sign Assist is
operating, while driving down a hill,
the vehicle speed may exceed the
set speed.In this case, the dis-
played set vehicle speed will be
highlighted and a buzzer will sound
to alert the driver.
■Dynamic radar cruise control with
full-speed range can be set when
●The shift lever is in D.
●The desired set speed can be set when the vehicle speed is approxi-
mately 30 km/h (20 mph) or more. (However, when the vehicle speed is set while driving at below approxi-
mately 30 km/h [20 mph], the set speed will be set to approximately 30 km/h [20 mph].)
■Accelerating after setting the vehi-
cle speed
The vehicle can accelerate by operating
the accelerator pedal. After accelerat- ing, the set speed resumes. However, during vehicle-to-vehicle distance con-
trol mode, the vehicle speed may decrease below the set speed in order to maintain the distance to the preceding
vehicle.
■When the vehicle stops while fol-
low-up cruising
●Pressing the “+RES” switch while the
vehicle ahead stops will resume fol- low-up cruising if the vehicle ahead starts off within approximately 3 sec-
onds after the switch is pressed.
●If the vehicle ahead starts off within 3
seconds after your vehicle stops, fol- low-up cruising will be resumed.
■Automatic cancelation of vehicle-to-vehicle distance control mode
Vehicle-to-vehicle distance control mode is automatically canceled in the follow-ing situations.
●VSC is activated.
●TRC is activated for a period of time.
●When the VSC or TRC system is
turned off.
●The sensor cannot detect correctly
because it is covered in some way.
●When the brake control or output
restriction control of a driving support system operates. (For example: Pre-Collision System, Drive-Start Control)
●The parking brake is operated.
●The vehicle is stopped by system con-trol on a steep incline.
●The following are detected when the vehicle has been stopped by system control:
• The driver is not wearing a seat belt. • The driver’s door is opened.• The vehicle has been stopped for
about 3 minutes
If vehicle-to-vehicle distance control mode is automatically canceled for any
reasons other than the above, there may be a malfunction in the system. Contact any authorized Toyota retailer
or Toyota authorized repairer, or any reli- able repairer.

●VSC is activated.
●TRC is activated for a period of time.
●When the VSC or TRC system is turned off.
●When the brake control or output restriction control of a driving support
system operates.(For example: Pre- Collision System, Drive-Start Control)
●The parking brake is operated.
If constant speed control mode is auto- matically canceled for any reasons other
than the above, there may be a malfunc- tion in the system. Contact any autho-rized Toyota retailer or Toyota
authorized repairer, or any reliable repairer.
■The Dynamic Radar Cruise Control with Road Sign Assist may not
operate properly when (if equipped)
As the Dynamic Radar Cruise Control
with Road Sign Assist may not operate properly in conditions in which RSA may not operate or detect correctly
( P.247), when using this function, make sure to check the speed limit sign displayed.
In the following situations, the set speed may not be changed to the recognized speed limit by pressing and holding the
“+RES”/“-SET” switch.
●If speed limit information is not avail-
able
●When the recognized speed limit is
the same as the set speed
●When the recognized speed limit is
outside of the speed range that the dynamic radar cruise control system can operate
■Brake operation
A brake operation sound may be heard and the brake pedal response may
change, but these are not malfunctions.
■Warning messages and buzzers for
dynamic radar cruise control with full-speed range
Warning messages and buzzers are
used to indicate a system malfunction or to inform the driver of the need for cau-tion while driving. If a warning message
is shown on the multi-information dis- play, read the message and follow the instructions. ( P.207, 383)
■When the sensor may not be cor-
rectly detecting the vehicle ahead
In the case of the following and depend- ing on the conditions, operate 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 cor- rectly detect these types of vehicles, the approach warning ( P.237) may not be
activated.
●Vehicles that cut in suddenly
●Vehicles traveling at low speeds
●Vehicles that are not moving in the same lane
●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.)

high ground clearance
■Conditions under which the vehi-
cle-to-vehicle distance control mode may not function correctly
In the case of the following conditions,
operate the brake pedal (or accelerator pedal, depending on the situation) as necessary.
As the sensor may not be able to cor- rectly detect vehicles ahead, the system may not operate properly.
●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 decel-
erates suddenly
●When driving on a road surrounded by
a structure, such as in a tunnel or on a bridge

static object detection and display
(warning buzzer sounds). Even at low speeds, there is a possibility that the object will come within 30 cm (1.0 ft.)
before the display is shown and the warning buzzer sounds.• It might be difficult to hear the buzzer
due to the volume of the audio system or air flow noise of the air conditioning system.
• It may be difficult to hear the sound of this system due to the buzzers of other systems.
■Objects which the system may not
be properly detected
The shape of the object may prevent the sensor from detecting it. Pay particular
attention to the following objects:
●Wires, fences, ropes, etc.
●Cotton, snow and other materials that absorb sound waves
●Sharply-angled objects
●Low objects
●Tall objects with upper sections pro-
jecting outwards in the direction of your vehicle
■Situations in which the system may not operate properly
Certain vehicle conditions and the sur- rounding environment may affect the ability of a sensor to correctly detect
objects. Particular instances where this may occur are listed below.
●There is dirt, snow, water drops or ice on a sensor. (Cleaning the sensors will resolve this problem.)
●A sensor is frozen. (Thawing the area will resolve this problem.)
In especially cold weather, if a sensor is frozen the sensor display may be displayed abnormally, or objects, such
as a wall, may not be detected.
●When a sensor or the area around a
sensor is extremely hot or cold.
●On an extremely bumpy road, on an
incline, on gravel, or on grass.
●When vehicle horns, vehicle detec-
tors, motorcycle engines, air brakes of large vehicles, the clearance sonar of other vehicles or other devices which
produce ultrasonic waves are near the vehicle
●A sensor is coated with a sheet of spray or heavy rain.
●If objects draw too close to the sensor.
●Pedestrians that are hard to reflect
ultrasonic waves (ex. skirts with gath- ers or frills).
●When objects that are not perpendicu-lar to the ground, not perpendicular to the vehicle traveling direction,
uneven, or waving are in the detection range.
●Strong wind is blowing
●When driving in inclement weather
such as fog, snow or a sandstorm
●When an object that cannot be
detected is between the vehicle and a detected object
●If an object such as a vehicle, motor-cycle, bicycle or pedestrian cuts in front of the vehicle or runs out from
the side of the vehicle
●If the orientation of a sensor has been
changed due to a collision or other impact
●When equipment that may obstruct a sensor is installed, such as a towing eyelet, bumper protector (an addi-
tional trim strip, etc.), bicycle carrier, or snow plow
●If the front of the vehicle is raised or lowered due to the carried load

●If the vehicle cannot be driven in a
stable manner, such as when the vehicle has been in an accident or is malfunctioning
●When a tire chains, compact spare tire or an emergency tire puncture repair
kit is used
■Situations in which the system may operate even if there is no possibil-ity of a collision
In some situations, such as the follow- ing, the system may operate even though there is no possibility of a colli-
sion.
●When driving on a narrow road
●When driving toward a banner, flag, low-hanging branch or boom barrier
(such as those used at railroad cross- ings, toll gates and parking lots)
●When there is a rut or hole in the sur-face of the road
●When driving on a metal cover (grat-ing), such as those used for drainage ditches
●When driving up or down a steep slope
●If a sensor is hit by a large amount of water, such as when driving on a
flooded road
●There is dirt, snow, water drops or ice
on a sensor. (Cleaning the sensors will resolve this problem.)
●A sensor is coated with a sheet of spray or heavy rain
●When driving in inclement weather such as fog, snow or a sandstorm
●When strong winds are blowing
●When vehicle horns, vehicle detec-
tors, motorcycle engines, air brakes of large vehicles, the clearance sonar of other vehicles or other devices which
produce ultrasonic waves are near the vehicle

PKSB (Parking Support
Brake)*
The Parking Support Brake
system consists of the follow-
ing functions that operate
when driving at a low speed or
backing up, such as when
parking. When the system
determines that the possibility
of a collision with a detected
object is high, a warning oper-
ates to urge the driver to take
evasive action. If the system
determines that the possibility
of a collision with a detected
object is extremely high, the
brakes are automatically
applied to help avoid the colli-
sion or help reduce the impact
of the collision.

Brake) system
WARNING
■Cautions regarding the use of the system
Do not overly rely on the system, as doing so may lead to an accident.
Always drive while checking the
safety of the surroundings of the vehi- cle.
Depending on the vehicle and road
conditions, weather, etc., the system may not operate.
The detection capabilities of sensors
and radars are limited. Always drive while checking the safety of the sur-roundings of the vehicle.
●The driver is solely responsible for safe driving. Always drive carefully,
taking care to observe your sur- roundings. The Parking Support Brake system is designed to pro-
vide support to lessen the severity of collisions. However, it may not operate in some situations.
●The Parking Support Brake system is not designed to stop the vehicle
completely. Additionally, even if the system has stopped the vehicle, it is necessary to depress the brake
pedal immediately as brake control will be canceled after approximately 2 seconds.
●It is extremely dangerous to check the system operations by intention-
ally driving the vehicle into the direction of a wall, etc. Never attempt such actions.
■When to disable the Parking Sup-port Brake
In the following situations, disable the Parking Support Brake as the system may operate even though there is no
possibility of a collision.
●When inspecting the vehicle using
a chassis roller, chassis dynamo or free roller
