Full-Speed Dynamic Radar Cruise Control
(DRCC) (if equipped)
1 The set speed may also be cancelled by depressing the brake pedal.2 The set speed may be resumed once vehicle speed exceeds 25 mph.
Vehicle will cruise at a set speed, decelerate to maintain selected distance 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 “ON-OFF” button. The “RADAR READY” or “
” indicator will come
on.
(2) Push the lever down to SET speed, push it up to Resume and pull it or depress brake to Cancel.
(3) Push up to increase the set speed, push down to decrease (1mph increments).

Note: If you hold the ON-OFF
button for 1.5 seconds or
more, the system switches to
constant speed control mode.
In vehicle-to-vehicle distance control mode, the vehicle automatically accelerates,
decelerates and stops to match the speed changes of the preceding vehicle at any
speed. ,n constant speed control mode the vehicle runs at a fi [ed speed.
Use the DRCC with full-speed range on freeways and highways.
Adjusting distance
This mode employs a radar sensor to detect the presence of vehicles up to
approximately 400ft (120m) ahead, determines the current vehicle-to-vehicle
following distance and operates to maintain a suitable following distance from the
vehicle ahead.
(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 distance
control.
(2) Deceleration cruising and follow-up cruising when a preceding vehicle
driving slower than the set speed appears When a vehicle is detected running ahead of you, the system automatically
decelerates your vehicle. When a greater reduction in vehicle speed is
necessary, the system applies the brakes (the stop lights will 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 by the driver. A warning
tone warns you when the system cannot decelerate sufficiently to prevent your
vehicle from closing in on the vehicle ahead.
Note:
Vehicle-to-vehicle distance may lessen when traveling on long downhill
slopes.
