the lever is operated
Large adjustment: The speed will continue to change while the lever is
held.
*1: When the set speed is shown in “km/h”
*2: When the set speed is shown in “MPH”
●Increasing the set speed by the accelerator pedal

When your vehicle is too close to
a vehicle ahead, and sufficient
automatic deceleration via the

example of this would be if
another driver cuts in front of you
while you are following 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
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

PRIUS_OM_OM47F32E_(EE)■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 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.
●When the brake control or output restriction control of a driving support sys-
tem operates. (For example: Pre-Collision System, Drive-Start Control)
If constant speed 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 reliable
repairer.
■The Dynamic Radar Cruise Control with Road Sign Assist may not oper-
ate properly when (vehicles with RSA [Road Sign Assist])
As the Dynamic Radar Cruise Control with Road Sign Assist may not oper-
ate properly in conditions in which RSA may not operate or detect correctly
(P. 327), 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 recog-
nized speed limit by pushing the lever up or down.
●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 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 caution while driving. If a warning message
is shown on the multi-information display, read the message and follow the
instructions. (P. 294, 589)

■Cruise control can be set when
●The shift position is in D.
●Vehicle speed is above approximately 30 km/h (20 mph).
■Accelerating after setting the vehicle speed
●The vehicle can be accelerated by operating accelerator pedal. After accel-
eration, the set speed resumes.
●Even without canceling the cruise control, the set speed can be increased
by first accelerating the vehicle to the desired speed and then pushing the
lever down to set the new speed.
■Automatic cancelation of cruise control
Cruise control is automatically canceled in any of the following situations.
●Actual vehicle speed falls more than approximately 16 km/h (10 mph) below
the set speed.
At this time, the memorized set speed is not retained.
●Actual vehicle speed is below approximately 30 km/h (20 mph).
●VSC is activated.

Normal mode
Suitable for normal driving.
When normal mode is selected, the “ECO MODE” and “PWR MODE”
indicators turn off.
Power mode
Suitable for when crisp handling and enhanced accelerator
response are desired, such as when driving on mountainous roads.
When power mode is selected, the “PWR MODE” indicator will illumi-
nate on the main display.
Eco drive mode
Suitable for driving that improves fuel economy by generating
torque in response to accelerator pedal operations more smoothly
than in normal mode.
When Eco drive mode is selected, the “ECO MODE” indicator will illumi-
nate on the main display.
While the air conditioning is being used, the system automatically
switches to air conditioning eco mode (P. 462), allowing for driving
that leads to even better fuel economy.
■When canceling Eco drive mode/power mode
●Press the switch again. Also, power mode will be canceled automatically
when the power switch is turned off.
●However, Normal mode and Eco drive mode will not be canceled automati-
cally until the switch is pressed, even if the power switch is turned off.
