Driving
This mode employs a radar to detect the presence of vehicles up to approx-
imately 100 m (328 ft.) ahead, d etermines the current vehicle-to-vehicle fol-
lowing distance, and operates to maintain a suitable following distance from
the vehicle ahead. The desired vehicle-to-vehicle distance can also be set
by operating the vehicle-to-vehicle distance switch.
When driving on downhill slopes, the vehicle-to-vehicle distanc e may become
shorter.
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver.
Example of deceleration cruising and follow-up cruising
When a preceding vehicle driving slower than the set speed appe ars
When a vehicle is detected running ahead of you, the system automatically deceler-
ates your vehicle. When a greater reduction in vehicle speed is necessary, the sys-
tem applies the brakes (the stop lights will come on at this ti me). The system will
respond to changes in the speed of the vehicle ahead in order t o maintain the vehi-
cle-to-vehicle distance set by the driver. Approach warning war ns you when the sys-
tem cannot decelerate sufficiently to prevent your vehicle from closing in on the
vehicle ahead.
When the vehicle ahead of you stops, your vehicle will also sto p (vehicle is stopped
by system control). After the vehicle ahead starts off, pressin g the “+RES” switch or
depressing the accelerator pedal (start-off operation) will res ume follow-up cruising.
If the start-off operation is not performed, system control con tinues to keep your
vehicle stopped.

• Hybrid system output restriction con- trol is operating.• The Parking Support Brake deter-
mines that an immediate brake opera- tion is necessary to avoid a collision.
■The Parking Support Brake func-tion (static objects) will stop oper-
ating when
The function will stop operating if any of the following conditions are met:
●Hybrid system output restriction con-
trol • The Parking Support Brake is dis-abled.
• The system determines that the colli- sion has become avoidable with nor-mal brake operation.
• The static object is no longer approxi- mately 2 to 4 m (6 to 13 ft.) away from the vehicle or in the traveling direction
of the vehicle.
●Brake control
• The Parking Support Brake is dis- abled.• Approximately 2 seconds have
elapsed since the vehicle was stopped by brake control.• The brake pedal is depressed after
the vehicle is stopped by brake con-
trol. • The static object is no longer approxi-mately 2 to 4 m (6 to 13 ft.) away from
the vehicle or in the traveling direction of the vehicle.

 P. 2 6 9
■Detection range of the Parking Sup- port Brake function (static objects)
The detection range of the Parking Sup-
port Brake function (static objects) dif- fers from the detection range of the Toyota parking assist-sensor. ( P.258)
Therefore, even if the Toyota parking assist-sensor detects an object and pro-vides a warning, the Parking Support
Brake function (static objects) may not start operating.
■Objects which the system may not be properly detected
 P. 2 5 6
■Toyota parking assist-sensor buzzer
Regardless of whether the Toyota park-
ing assist-sensor buzzer is enabled or not ( P.254), if the Parking Support Brake function (static objects) is enabled
( P.266), the front or rear sensors detect an object and brake control is performed, the Toyota parking assist-
sensor buzzer will sound to notify the driver of the approximate distance to the object.
