■ Dynamic radar cruise control
with full-speed range can be set
when
● The shift lever is in D.
● The desired set speed can be set
when the vehicle speed is approx-
imately 20 mph (30 km/h) or more.
(However, when the vehicle speed
is set while driving at below
approximately 20 mph [30 km/h],
the set speed will be set to
approximately 20 mph [30 km/h].)
■ Accelerating after setting the
vehicle speed
The vehicle can accelerate by oper-
ating the accelerator pedal. After
accelerating, the set speed
resumes. However, during vehicle-
to-vehicle distance control mode,
the vehicle speed may decrease
below the set speed in order to
maintain the distance to the preced-
ing vehicle.
■ When the vehicle stops while
follow-up cruising
● Pressing the “+RES” switch while
the vehicle ahead stops will
resume follow-up cruising if the
vehicle ahead starts off within
approximately 3 seconds after the
switch is pressed.
● If the vehicle ahead starts off
within 3 seconds after your vehicle
stops, follow-up cruising will be
resumed.
■ Automatic cancelation of vehi-
cle-to-vehicle distance control
mode
Vehicle-to-vehicle distance control
mode is automatically canceled in
the following situations.
● VSC is activated.
● TRAC is activated for a period of
time.
● When the VSC or TRAC system is
turned off.
● The sensor cannot detect cor-
rectly because it is covered in
some way.
● When the brake control or output
restriction control of a driving sup-
port system operates.
(For example: Pre-Collision System,
Drive-Start Control)
● The parking brake is operated.
● The vehicle is stopped by system
control on a steep incline.
● The following are detected when
the vehicle has been stopped by
system control:
• The driver is not wearing a seat
belt.
• The driver’s door is opened.
• The vehicle has been stopped for
about 3 minutes
If vehicle-to-vehicle distance control
mode is automatically canceled for
any reasons other than the above,
there may be a malfunction in the
system. Contact your Toyota dealer.

stant speed control mode
