■ Automatic cancelation of vehicle-to-vehicle distance control
Vehicle-to-vehicle distance control driving is automatically canceled in the fol-
lowing situations:
● Actual vehicle speed falls below approximately 40 km/h (25 mph).
● VSC is activated.
● The sensor cannot operate correctly because it is covered in some way.
● The windshield wipers are operating at high speed (when the wiper switch is
set to the AUTO mode or the high speed wiper operation position).
If vehicle-to-vehicle distance control driving is automatically canceled for any
other reason, there may be a malfunction in the system. Contact any autho-
rized Toyota dealer or repairer, or another duly qualified and equipped profes-
sional.
■ Automatic cancelation of constant speed control
The cruise control will stop maintaining the vehicle speed in the following situ-
ations:
● Actual vehicle speed is more than approximately 16 km/h (10 mph) below
the set vehicle speed.
At this time, the memorized set speed is not retained.
● Actual vehicle speed falls below approximately 40 km/h (25 mph).
● VSC is activated.
■ Radar sensor and grille cover
Always keep the sensor and grille cover clean to ensure that the vehicle-to-
vehicle distance control operates properly. (Some obstructions, such as
snow, ice and plastic objects, cannot be detected by the obstruction sensor.)
Dynamic radar cruise control (vehicle-to-vehicle distance control mode) is
canceled if an obstruction is detected. (Constant speed control mode can be
used.)
■ Warning lights, warning messages and buzzers for dynamic radar cruise
control
Warning lights, warning messages and buzzers are used to indicate a system
malfunction or to inform the driver of the need for caution while driving.
