■Automatic cancelation of vehicle -to-vehicle distance control
Vehicle-to-vehicle distance control driving is automatically canceled in the
following situations:
● Actual vehicle speed falls below approximately 25 mph (40 km/h).
● Enhanced 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 high speed windshield wiper operation position).
If vehicle-to-vehicle distance control dr iving is automatically canceled for any
other reason, there may be a malfunction in the system. Contact your Toyota
dealer.
■ Automatic cancelation of constant speed control
The cruise control will stop maintaining the vehicle speed in the following sit-
uations:
●Actual vehicle speed is more than approximately 10 mph (16 km/h)
below the set vehicle speed.
At this time, the memorized set speed is not retained.
● Vehicle speed falls below appr oximately 25 mph (40 km/h).
● Enhanced 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) will
be canceled if dirt is detected. (Constant speed control mode can be used).

CAUTION
■Precautions for the Remote Air Conditioning System
●Do not use the system if people are in the vehicle.
• Even when the system is in use, the internal temperature may still
reach a high level due to features such as the automatic shut-off. Chil-
dren and pets left inside the vehicle may suffer heatstroke or dehydra-
tion, or could result in death or serious injury.
• The wipers can be operated during system operation. Children or pets left inside the vehicle may mistakenly operate these and cause an acci-
dent.
● Depending on the surrounding environment, signals from the wireless
switch may transmit further than expected. Pay appropriate attention to
the vehicle’s surroundings and use the switch only when necessary.
● Turn the wipers off. If the Remote Air Conditioning System operates while
the wiper switch is in the on position, the wipers may operate and objects
may get caught in the wiper blades.
● Do not operate the if the hood is open. The air conditioning may
operate unintentionally and objects may be drawn into the electrical cool-
ing fan.
NOTICE
■To prevent the hybrid battery (tractio n battery) from being discharged
