■Dynamic radar cruise control with full-speed range can be set when
● The shift lever is in D.
● Vehicle speed is above approximately 50 km/h (30 mph).
However, when a preceding vehicle is detected, the dynamic radar cruise
control with full-speed range can be set even if the vehicle speed is at or
below approximately 50 km/h (30 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-vehicle distance
control mode, the vehicle speed may decrease below the set speed in order
to maintain the distance to the preceding vehicle.
■ Automatic cancelation of vehicle-to-vehicle distance control mode
Vehicle-to-vehicle distance control mode is automatically canceled in the fol-
lowing situations.
● Actual vehicle speed falls below approximately 40 km/h (25 mph) when
there are no vehicles ahead.
● The preceding vehicle leaves the lane when your vehicle is following at a
vehicle speed below approximately 40 km/h (25 mph). Otherwise, the sen-
sor can not properly detect the vehicle.
● VSC is activated.
● TRC is activated for a period of time.
● When the VSC or TRC system is turned off by pressing the VSC off switch.
● 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 canceled for any
other reason, there may be a malfunction in the system. Contact any autho-
rized Toyota retailer or Toyota authorized repairer, or any reliable repairer.

■ Automatic cancelation of constant speed control mode
Constant speed control mode is automatically canceled in the following 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 40 km/h (25 mph).
● VSC is activated.
● TRC is activated for a period of time.
● When the VSC or TRC system is turned off by pressing the VSC off switch.
● Pre-collision braking is activated.
If constant speed control mode is automatically canceled for any other rea-
son, there may be a malfunction in the system. Contact any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer.
■ 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 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 detecting the vehicle ahead
In the case of the following and depending 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 correctly detect these types of vehicles, the
approach warning ( P. 345) may not be activated.
● Vehicles that cut in suddenly
● Vehicles traveling at low speeds
● Vehicles that are not moving in the same lane

■ Conditions under which the vehicle-to-vehicle distance control mode
may not function correctly
In the case of the following conditions, operate the brake pedal (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 the road curves or when the lanes
are narrow
● When steering wheel operation or your
position in the lane is unstable

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 and follow-up cruising
When a preceding vehicle driving slower than the set speed
appears
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 (the stop lights will come on at
this time). The system will respond to changes in the speed of the vehicle
ahead in order to maintain the vehicle-to-vehicle distance set by the driver.
Approach warning warns you when the system cannot decelerate suffi-
ciently to prevent your vehicle from closing in on the vehicle ahead.
Example of acceleration
When there are no longer any preceding vehicles driving slower
than the set speed
The system accelerates until the set speed is reached. The system then
returns to constant speed cruising.

Select a distance from the table below. Note that the distances shown
correspond to a vehicle speed of 80 km/h (50 mph). Vehicle-to-vehicle
distance increases/decreases in accordance with vehicle speed.
Pulling the lever toward you
cancels the speed control.
The speed control is also canceled
when the brake pedal is
depressed.
Pushing the lever up resumes
the cruise control and returns
vehicle speed to the set speed.
However, cruise control does not resume when the vehicle speed is
approximately 40 km/h (25 mph) or less.

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 vehi-
cle-to-vehicle distance.
■Warnings may not occur when
In the following instances, warnings may not occur even when the
vehicle-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 control speed was set
● When depressing the accelerator pedal

■ When the sensor may not be correctly detecting the vehicle ahead
In the case of the following and depending 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 correctly detect these types of vehicles, the
approach warning ( P. 362) 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

To change the set speed, operate the lever until the desired set speed
is obtained.
Increases the speed
Decreases the speed
Fine adjustment: Momentarily
move the lever in the desired
direction.
Large adjustment: Hold the lever
in the desired direction.
The set speed will be increased or decreased as follows:
Fine adjustment: By approximately 1 km/h (0.6 mph)*1 or 1 mph (1.6 km/h)*2
each time the lever is operated.
Large adjustment: The set speed can be increased or decreased continu-
ally until the lever is released.
*1: When the set speed is shown in “km/h”
*2: When the set speed is shown in “MPH”
Pulling the lever toward you
cancels the constant speed
control.
The speed setting is also canceled
when the brake pedal or clutch
pedal (manual transmission only)
is depressed.
Pushing the lever up resumes
the constant speed control.
However, resuming is available when the vehicle speed is more than
approximately 40 km/h (25 mph).
