Do not use the wipers, as they may damage the windshield.
■ When the washer fluid tank is empty
Do not operate the switch continually as the washer fluid pump may over-
heat.
■ When a nozzle becomes blocked
In this case, contact your Toyota dealer.
Do not try to clear it with a pin or other object. The nozzle will be damaged\
.
■ To prevent 12-volt battery discharge
Do not leave the wipers on longer than necessary when the hybrid system
is off.

Vehicle-to-vehicle distance control driving is automatically canceled in the fol-
lowing 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

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 situ-
ations:
● 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.
● Actual vehicle speed falls below approximately 25 mph (40 km/h).
● Enhanced VSC is activated.
