When constant speed control mode is selected, your vehicle will main-
tain a set speed without controlling the vehicle-to-vehicle dis tance.
Select this mode only when vehicle-to-vehicle distance control mode
does not function correctly due to a dirty radar, etc.
With the cruise control off,
press and hold the “ON-OFF”
button for 1.5 seconds or more.
Immediately after the “ON-OFF”
button is pressed, the dynamic
radar cruise control indicator will
come on. Afterwards, it switches to
the cruise control indicator.
Switching to constant speed con-
trol mode is only possible when
operating the lever with the cruise
control off.
Accelerate or decelerate, with
accelerator pedal operation, to
the desired vehicle speed (at or
above approximately 30 km/h
[20 mph]) and push the lever
down to set the speed.
Cruise control “SET” indicator will
come on.
The vehicle speed at the moment the lever is released becomes t he set
speed.

When this function is enabled and the system is operating in vehicle-
to-vehicle distance control mode (P. 412), when a speed limit sign is
detected, the recognized speed limit will be displayed with an up/
down arrow. The set speed can be increased/reduced to the recog -
nized speed limit by pressing and holding the “+RES”/“-SET” swi tch.
● When the current set speed is lower than the recognized speed
limit
Push the lever up
● When the current set speed is higher than the recognized speed
limit
Push the lever down
Dynamic Radar Cruise Control with Road Sign Assist can be enabl ed/
disabled in on the multi-information display. (P. 788)
When the Dynamic Radar Cruise Control with Road Sign Assist is
operating, while driving down a hill, the vehicle speed may exc eed the
set speed.
In this case, the displayed set vehicle speed will be highlight ed 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 approximately
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 approxima tely 30 km/h
[20 mph].)
■ Accelerating after setting the vehicle speed
The vehicle can accelerate by operating the accelerator pedal. After acceler-
ating, the set speed resumes. However, during vehicle-to-vehicl e distance
control mode, the vehicle speed may decrease below the set spee d in order
to maintain the distance to the preceding vehicle.
■ When the vehicle stops while follow-up cruising
● Pushing the lever up while the vehicle ahead stops will resume follow-up
cruising if the vehicle ahead starts off within approximately 3 seconds after
the lever is pushed up.
● 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 cance led in the fol-
lowing 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.
● Pre-collision braking is activated.
● The parking brake is operated.
● The vehicle is stopped by system control 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 ca nceled for any
reasons other than the above, there may be a malfunction in the system.
Contact any authorized Toyota retailer or Toyota authorized rep airer, or any
reliable repairer.

■ Automatic cancelation of constant speed control mode
Constant speed control mode is automatically canceled in the fo llowing situa-
tions:
● Actual vehicle speed is more than approximately 16 km/h (10 mph) below
the set vehicle speed.
● Actual vehicle speed falls below approximately 30 km/h (20 mph).
● VSC is activated.
● TRC is activated for a period of time.
● When the VSC or TRC system is turned off.
● Pre-collision braking is activated.
If constant speed control mode is automatically canceled for an y reasons
other than the above, there may be a malfunction in the system. Contact any
authorized Toyota retailer or Toyota authorized repairer, or an y reliable
repairer.
■ The Dynamic Radar Cruise Control with Road Sign Assist may not oper-
ate properly when
As the Dynamic Radar Cruise Control with Road Sign Assist may n ot operate
properly in conditions in which RSA may not operate or detect c orrectly
( P. 406), when using this function, make sure to check the speed limit sign
displayed.
In the following situations, the set speed may not be changed t o the recog-
nized speed limit by pressing and holding the “+RES”/“-SET” swi tch.
● If speed limit information is not available
● 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 respon se 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 malf unction 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. ( P. 365, 690)

■ When the sensor may not be correctly detecting 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. 418) 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.)
● Preceding vehicle has an extremely high
ground clearance

■ Conditions under which the vehicle-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 ahea d, 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 the 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
