Intended for highway use, Full-Speed Range Dynamic Radar Cruise Control \
(DRCC) lets you drive at a preset speed. The system is designed to fun\
ction
between 0-110 mph* and uses vehicle-to-vehicle distance control, helping\
maintain
a preset distance from the vehicle ahead of you.*
* See www.toyota.com/safety-sense for more information.
Refer to the Toyota Owner’s Manual for a list of additional situation\
s in which the
system operation may be limited.

stance from a
slower vehicle traveling in front and accelerate back up to the selected\
speed if the
vehicle in front changes lanes or speeds up.
(1) Push the “
” to turn DRCC system ON. The “Radar Ready” and “”
indicator will come on.
(2) Use the steering wheel controls to increase speed by pushing “ +RES” or

ADJUSTING DISTANCE
This mode employs a radar sensor to detect the presence of a preceding v\
ehicle
up to approximately 328 ft (100 m) ahead, determines the current vehic\
le-to-vehicle
following distance and operates to maintain a preset following distance \
from the
vehicle ahead. These distances vary based on vehicle speed.

(1) Constant speed cruising when there are no vehicles ahead
The vehicle travels at the speed set by the driver. The desired vehicle-\
to-
vehicle distance can also be set by operating the vehicle-to-vehicle dis\
tance
control.
(2) Deceleration cruising and follow-up cruising when a preceding vehicle
driving slower than the set speed appears When a slower vehicle is detected running ahead of you, the system
automatically decelerates your vehicle. When a greater reduction in vehi\
cle
speed is necessary, the system may apply the brakes (the brake lights w\
ill
come on at this time). The system will respond to changes in the speed \
of the
vehicle ahead in order to maintain the vehicle-to-vehicle distance set b\
y the
driver. A warning tone warns you when the system cannot decelerate suffi\
ciently
to prevent your vehicle from closing in on the vehicle ahead.
Note: Vehicle-to-vehicle distance will close in when traveling on long downhill
slopes.
