vehicle speed. However, while in
vehicle-to-vehicle distance control
mode, the vehicle speed may
decrease to below the set vehicle
speed in order to maintain the dis-
tance from the preceding vehicle.
■ When the vehicle is stopped by
system control during follow-up
cruising
● When the “+RES” switch is
pressed while the vehicle is
stopped by system control, if the
preceding vehicle starts off within
approximately 3 seconds, fol-
low-up cruising will resume.
● If the preceding vehicle starts off
within approximately 3 seconds of
the vehicle being stopped by sys-
tem control, follow-up cruising will
resume.
■ Automatic cancellation of vehi-
cle-to-vehicle distance control
mode
In the following situations, vehi-
cle-to-vehicle distance control mode
will be canceled automatically:
● When the brake control or output
restriction control of a driving sup-
port system operates
(For example: Pre-Collision Sys-
tem, drive-start control)
● When the parking brake has been
operated
● When the driver's seat belt is
unfastened while driving
● When the Pre-Collision System is
disabled
● When the vehicle is stopped by
system control on a steep incline
● When any of the following are
detected while the vehicle is
stopped by system control:
• The driver’s seat belt is unfas-
tened
• The driver’s door is opened
• Approximately 3 minutes have
elapsed since the vehicle was
stopped
The parking brake may be actived
automatically.
● Situations in which some or all of
the functions of the system cannot
operate: P. 19 9
■ Dynamic radar cruise control
system warning messages and
buzzers
For safe use: P.1 94
■ Preceding vehicles that the sen-
sor may not detect correctly
In the following situations, depend-
ing on the conditions, if the system
cannot provide sufficient decelera-
tion or acceleration is necessary,
operate the brake pedal or accelera-
tor pedal.
As the sensor may not be able to
correctly detect these types of vehi-
cles, the approach warning
(P.236) may not operate.
● When a vehicle cuts in front of
your vehicle or changes lanes
away from your vehicle extremely
slowly or quickly
● When changing lanes
● When a preceding vehicle is driv-
ing at a low speed
● When a vehicle is stopped in the
same lane as the vehicle
● When a motorcycle is traveling in
the same lane as the vehicle
■ Conditions under which the
system may not operate cor-
rectly
In the following situations, operate
the brake pedal (or accelerator
pedal, depending on the situation)
as necessary.
As the sensor may not be able to
correctly detect a vehicle, the sys-
tem may not operate properly.
● When a preceding vehicle brakes
suddenly
● When changing lanes at low
speeds, such as in a traffic jam
