(above approximately 30 mph
[50 km/h]) 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 the
set speed.
If the lever is operated while the
vehicle speed is below approxi-
mately 30 mph (50 km/h) and a
preceding vehicle is present, the
set speed will be adjusted to
approximately 30 mph (50 km/h).

correspond to a vehicle speed of 50 mph (80 km/h). Vehicle-to-vehicle
distance increases/decreases in accordance with vehicle speed.
When the vehicle is stopped by system control, the vehicle-to-vehicle

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

■Automatic cancelation of co nstant 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 by pressing the VSC OFF
switch.
● Pre-collision braking is activated.
● Intelligent Clearance Sonar is operated. (if equipped)
If constant speed control mode is automatically canceled for any other rea-
son, there may be a malfunction in the system. Contact your Toyota dealer.
■ Warning messages and buzzers for dy namic 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. 307) may not be activated.
● Vehicles that cut in suddenly
● Vehicles traveling at low speeds
● Vehicles that are not moving in the same lane

■Cruise control can be set when
●The shift position is in D.
● Vehicle speed is above approximately 25 mph (40 km/h).
■ Accelerating after setting the vehicle speed
●The vehicle can be accelerated by operating accelerator pedal. After accel-
erating, 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 situati\
ons.
●Actual vehicle speed falls more than approximately 10 mph (16 km/h) below
the set speed.
At this time, the memorized set speed is not retained.
● Actual vehicle speed is below approximately 25 mph (40km/h).
● VSC is activated.
● TRAC is activated for a period of time.
● When the VSC or TRAC system is turned off by pressing the VSC OFF
switch.
● Intelligent Clearance Sonar is operated. (if equipped)
■ If “Check Cruise Control System Visi t Your Dealer” is displayed on the
multi-information display
Press the “ON-OFF” button once to deactivate the system, and then press
the button again to reactivate the system.
If the cruise control speed cannot be set or if the cruise control cancels imme-
diately after being activated, there may be a malfunction in the cruise control
system. Have the vehicle inspected by your Toyota dealer.

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 illuminate
on the main display.
Eco drive mode
Suitable for driving that improv es 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. 514), 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.
