cle speed may decrease below the set speed in order to maintain the dis-
tance to the vehicle ahead.

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 is
set to 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 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.
● Vehicle speed falls below approximately 25 mph (40 km/h).
