Full-Speed Range Dynamic Radar Cruise Control
(DRCC)
Full-Speed Range DRCC helps maintain a pre-set distance to a preceding vehicle
when the preceding vehicle is traveling at a lower speed. This mode is always
selected first when the cruise control button is depressed. Constant speed cruise
control mode is also available. Full-Speed Range DRCC is designed to function at
speeds between 0 to approximately 110 MPH and is intended for highway use.

The speed control may also be canceled by depressing the brake pedal. Refer to page 52 for switching to Constant Speed (Cruise) Control Mode.
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.

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.
Deceleration cruising and follow-up cruising when a preceding vehicle
driving slower than the set speed appears

decelerates your vehicle. When a greater reduction in vehicle speed is

Note: When your vehicle is too close to a vehicle ahead, and sufficient automatic
deceleration via the cruise control is not possible, the display will flash and the
buzzer will sound to alert the driver. An example of this would be if another driver
cuts in front of you while you are following a vehicle. Depress the brake pedal to
ensure an appropriate vehicle-to-vehicle distance.
If you are already using DRCC “,” push ON-OFF button to turn the system off
first, then push and hold ON-OFF button for at least 1.5 seconds to switch.
Note: When the engine is turned off, it will automatically default to DRCC.
Acceleration when there are no longer any preceding vehicles driving
slower than the set speed
The system accelerates until the set speed is reached. The system then
returns to constant speed cruising.
To adjust speed or cancel, see steps (2) and (3) of ADJUSTING SET SPEED on
page 50.
Refer to the Toyota Owner’s Manual for additional information on DRCC operation,
settings adjustments, limitations, and precautions before attempting to use it.

AHB is a safety system designed to help drivers see more of what’s ahead at
nighttime while reducing glare for oncoming drivers. When enabled, AHB uses a
forward-facing camera to help detect the headlights of oncoming vehicles and tail
lights of preceding vehicles, then automatically switches between high and low
beams as appropriate to provide the most light possible and enhance forward
visibility. By using high beams more frequently, the system may allow earlier
detection of pedestrians and obstacles.
Refer to the Toyota Owner’s Manual for additional information on AHB operation,
settings adjustments, limitations, and precautions before attempting to use it.
