AFS (Adaptive Front-lighting System) (if equipped)  
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 head-  
lights, 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 hybrid system is operating  
• The parking brake is released  
• The headlight switch is in the  
,
,
or  
* position  
*: When the surroundings are bright  
The daytime running lights remain on after they illuminate, even if the park-  
ing 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 (if equipped)  
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 sys-  
tem to malfunction.  
Air conditioning operation may also be  
interrupted.  
Automatic light off system  
When the headlights come on: The headlights and tail lights turn off 30 sec-  
onds after a door is opened and closed if the power switch is turned to  
ACCESSORY mode or turned off. (The lights turn off immediately if  
the key is pressed after all the doors are locked.)  
on  
When only the tail lights come on: The tail lights turn off automatically if the  
power switch is turned to ACCESSORY mode or turned off and the driver’s  
door is opened.  
To turn the lights on again, turn the power switch to ON mode, or turn the light  
switch to the  
or  
,
,
or  
position once and then back to the  
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 Toy-  
ota dealer.

(Customizable features: P. 678)  
NOTICE

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