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

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)

■

Automatic light off system

●

When the headlights come on: The headlights and tail lights turn off 30 sec-
onds after the driver’s door is opened and closed if the power switch is
turned to ACCESSORY mode or turned off. (The lights turn off immediately
if

on the key is pressed after all the doors are locked.)

●

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

position once and then back to the

position.

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 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.

●

In  the  situations  shown  below,  the  system  may  not  be  able  to  accurately
detect  surrounding  brightness  levels.  This  may  cause  the  low  beams  to
remain  on or the  high beams to  cause problems  for pedestrians, vehicles
ahead or other parties. In these cases, manually switch between the high
and low beams.
• In bad weather (rain, snow, fog, sandstorms etc.)
• The windshield is obscured by fog, mist, ice, dirt etc.
• The windshield is cracked or damaged.
• The front camera is deformed or dirty.
• The front camera temperature is extremely high.
• Surrounding brightness levels are equal to those of headlights, tail lights

or fog lights.

• Vehicles ahead have headlights that are either switched off, dirty, are

changing color, or are not aimed properly.

• When driving through an area of intermittently changing brightness and

darkness.

• When frequently and repeatedly driving ascending/descending roads, or

roads with rough, bumpy or uneven surfaces (such as stone-paved
roads, gravel tracks etc.).

• When frequently and repeatedly taking curves or driving on a winding

road.

• There is a highly reflective object ahead of the vehicle, such as a sign or

a mirror.

• The back of a vehicle ahead is highly reflective, such as a container on a

truck.

• The vehicle’s headlights are damaged or dirty.
• The vehicle is listing or tilting, due to a flat tire, a trailer being towed etc.
