DISABLING LANE CENTERING FUNCTION
LANE CENTERING
The lane centering function is linked with Full-Speed Range Dynamic Radar Cruise
Control (DRCC) and provides the required assistance by operating the steering
wheel to keep the vehicle in its current lane.
When dynamic radar cruise control with full-speed range is not operating, the lane
centering function does not operate.

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.

TOYOTA SAFETY SENSE™
ADJUSTING DISTANCE
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.
(1) (2) (3)
(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.
Note: Vehicle-to-vehicle distance will close in when traveling on long downhill
slopes.
To change the vehicle-to-vehicle distance
Push the “” button to cycle
through the settings, which will
change progressively.

SWITCHING TO CONSTANT SPEED (CRUISE) CONTROL MODE
SETTING CONSTANT SPEED (CRUISE) CONTROL
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.
(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.
To adjust speed or cancel, see steps (2) and (3) of ADJUSTING SET SPEED on
page 43.
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.

TOYOTA SAFETY SENSE™
(1) Push the lever away from you with the headlight switch is in the “AUTO” or “

(2) Depress the Automatic High Beam “” switch.
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 and the high beam indicator “” turns on.
When all of the following conditions are met, the 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 street lights on the road ahead.
If any of the following conditions occur, the 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.

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 camera and/or
navigation system 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 notifies the
driver using a notification display and notification buzzer.
