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.

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 “
” 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
decrease the speed by pushing “-SET”. Push and hold to make a large
adjustment or push each time to make fine adjustments (1 mph [1.6 km/h] or 1
km/h [0.6 mph] increments).
(3) Push “Cancel” to cancel the speed control operation.

ADJUSTING DISTANCE
To change the vehicle-to-vehicle distance

Push the “
” button to cycle
through the settings, which will
change progressively.
This mode employs a radar sensor to detect the presence of a preceding vehicle
up to approximately 328 ft (100 m) ahead, determines the current vehicle-to-vehicle
following distance and operates to maintain a preset following distance from the
vehicle ahead. These distances vary based on vehicle speed.
LONG
(default setting) MIDDLE

Note: Vehicle-to-vehicle distance will close in when traveling on long downhill
slopes.

(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 brake 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.

ADJUSTING DISTANCE (CONTINUED)
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.
(3) 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.
SWITCHING TO CONSTANT SPEED (CRUISE) CONTROL MODE
SETTING CONSTANT SPEED (CRUISE) CONTROL
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.
Refer to the Toyota Owner’s Manual for additional information on DRCC operation,
settings adjustments, limitations, and precautions before attempting to use it.

Automatic High Beams (AHB)
ACTIVATING THE AHB SYSTEM
CONDITIONS WHERE AHB WILL TURN ON/OFF AUTOMATICALLY
When all of these conditions are met, high beams will be automatically turned on
(after approximately 1 second):
• Vehicle speed is above approximately 21 mph (34 km/h).
• The area ahead of the vehicle is dark.
• There are no oncoming or preceding vehicles with headlights or tail lights turned on.
• There are few streetlights on the road ahead.
If any of these conditions occur, high beams will be automatically turned off: • Vehicle speed drops below approximately 17 mph (27 km/h).
• The area ahead of the vehicle is not dark.
• Oncoming or preceding vehicles have headlights or tail lights turned on.
• There are many streetlights on the road ahead.
AHB is a safety system designed to help drivers see more of what’s ahead at
nighttime while reducing glare for oncoming drivers, AHB uses an in-vehicle
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.
(2) (1)
(1) Press the “
” switch.
(2) Push lever away from you with the headlight switch is in the “
” or “AUTO”
position.
The AHB indicator will come on when the headlights are turned on automatically
to indicate that the system is active.
Note: Pull the lever back toward you or press the AHB switch to turn the AHB
system off.
The AHB indicator will turn off. To turn switch to “
” position and the manual
high beam indicator “

Road Sign Assist (RSA)
Road Sign Assist is designed to help ensure drivers are kept informed. The RSA
system recognizes specific road signs using a forward-facing intelligent camera to
provide information to the driver via a Multi-information Display (MID). If the system
judges that the vehicle is being driven over the speed limit, or performing actions
prohibited by other support types of road signs, it alerts the driver using a warning
display and may sound a warning buzzer.
