Turning on the high beam headlights

1 With the headlights on, push the lever away from you to turn on the high beams. Pull the lever toward you to the center position to turn the high beams off.

2 Pull the lever toward you and release it to flash the high beams once. You can flash the high beams with the headlights on or off.

AFS (Adaptive Front-lighting System) secures excellent visibility at intersections and on curves by automatically adjusting the direction of the light axis of the headlights according to vehicle speed and the degree of the tire’s angle as controlled by steering input.

AFS operates at speeds of approximately 6 mph (10 km/h) or higher.

■Daytime running light system

●The daytime running lights illuminate using the same lights as the headlights, and illuminate dimmer than the headlights.

●To make your vehicle more visible to other drivers during daytime driving, the daytime running lights turn on automatically when all of the following conditions are met. (The daytime running lights are not designed for use at night.)

  • The engine is running
  • The parking brake is released
  • The headlight switch is in the DRL, O,  , or AUTO * position

*: When the surroundings are bright

The daytime running lights remain on after they illuminate, even if the parking brake is set again.

●For the U.S.A.: Daytime running lights can be turned off by operating the switch.

●Compared to turning on the headlights, the daytime running light system offers greater durability and consumes less electricity, so it can help improve fuel economy.

■Headlight control sensor

The sensor may not function properly if an object is placed on the sensor, or anything that blocks the sensor is affixed to the windshield.

Doing so interferes with the sensor detecting the level of ambient light and may cause the automatic headlight system to malfunction.

Air conditioning operation may also be interrupted.

■Automatic light off system

●When the headlights come on: The headlights and tail lights automatically turn off after 30 seconds when all doors are closed with the engine switch turned to ACC or OFF. (The lights turn off immediately if the button on the wireless remote control is pressed after all doors are locked.)

●When only the tail lights come on: The tail lights turn off automatically with the engine switch turned to ACC or OFF and the driver’s door is opened.

To turn the lights on again, turn the engine switch to ON, or turn the headlight switch off once and then back to the or position.

■ Automatic headlight leveling system (vehicles with AFS)

The level of the headlights is automatically adjusted according to the number of passengers and the loading condition of the vehicle to ensure that the headlights do not interfere with other road users.

■ 12-volt battery-saving function

In order to prevent the 12-volt battery of the vehicle from discharging, if the headlights and/or tail lights are on when the power switch is turned off, the 12-volt battery saving function will operate and automatically turn off all the lights after approximately 20 minutes.

When any of the following are performed, the 12-volt battery-saving function is canceled once and then reactivated. All the lights will turn off automatically 20 minutes after the 12-volt battery-saving function has been reactivated:

● When the headlight switch is operated
● When a door is opened or closed

■ If “Headlight System Malfunction Visit Your Dealer” is displayed on the multi-information display

The system may be malfunctioning. Have the vehicle inspected by your Toyota dealer.

■ If the AFS OFF indicator flashes (vehicles with AFS)

It may indicate a malfunction in the system. Contact your Toyota dealer.

■ Customization

Settings (e.g. light sensor sensitivity) can be changed.

NOTICE
■ To prevent 12-volt battery discharge

Do not leave the lights on longer than necessary when the hybrid system is off.
