4-3. Operating the lights and wipers

?

Daytime running light system (if equipped)

?

Bulb type: The daytime running lights illuminate using the same lights as the
headlights and illuminate dimmer than the headlights.

?

LED type: The daytime running lights illuminate using the same lights as the
parking lights and illuminate brighter than the parking lights.

?

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

(Canada only),

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
headlight 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 sys-
tem to malfunction.

Automatic High Beam

Push the lever away from you with
the headlight switch in the
position.

The Automatic High Beam indica-
tor will come on when the head-
lights are turned on automatically
to indicate that the system is
active.

When all of the following conditions are fulfilled, high beam will be
automatically turned on (after approximately 1 second):

?

Vehicle speed is above approximately 20 mph (32 km/h).

?

The area ahead of the vehicle is dark.

?

There are no oncoming or preceding vehicles with headlights or tail
lights turned on.

If any of the following conditions are fulfilled, high beam will be auto-
matically turned off:

?

Vehicle speed drops below approximately 20 mph (32 km/h).

?

The area ahead of the vehicle is not dark.

?

Oncoming or preceding vehicles have headlights or tail lights
turned on.

The Automatic High Beam uses an in-vehicle camera sensor to
assess the brightness of streetlights, the lights of oncoming and
preceding vehicles, etc., and automatically turns high beam on
or off as necessary.

The Automatic High Beam can be operated when
The engine switch is in the “ON” position (vehicles without a smart key sys-
tem) or IGNITION ON mode (vehicles with a smart key system).

?

Camera sensor detection information

?

High beam may not be automatically turned off in the following situations:
• When oncoming vehicles suddenly appear from a curve.
• When the vehicle is cut in front of by another.

?

High beam may be turned off if an oncoming vehicle that is using fog lights
without using the headlights is detected.

?

Houselights, streetlights, red traffic signals, and illuminated billboards or
signs may cause the high beam to turn off.

?

The following factors may affect the amount of time taken to turn high beam
on or off:
• The brightness of headlights, fog lights, and tail lights of oncoming and

preceding vehicles

• Road conditions (wetness, ice, snow etc.)
• The number of passengers and amount of baggage

?

High beam may be turned on or off when unexpected by the driver.

?

In the situations below, the system may not be able to correctly detect the
surrounding brightness levels, and may flash or expose nearby pedestrians
to the high beam. Therefore, you should consider turning the high beam on
or off manually rather than relying on the Automatic High Beam system.
• 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 camera sensor is deformed or dirty.
• 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 vehicle’s headlights are damaged or dirty.
• The vehicle is lifting or tilting, due to a flat tire, a trailer being towed etc.
• The high beam and low beam are repeatedly being switched between in

an abnormal manner.

• The driver believes that the high beam may be causing problems or dis-

tress to other drivers or pedestrians nearby.

WARNING

?

Caution regarding the use of windshield wipers in “AUTO” mode
The windshield wipers may operate unexpectedly if the sensor is touched or
the windshield is subject to vibration in “AUTO” mode. Take care that your
fingers etc. do not become caught in the windshield wipers.

?

Caution regarding the use of washer fluid
When it is cold, do not use the washer fluid until the windshield becomes
warm. The fluid may freeze on the windshield and cause low visibility. This
may lead to an accident, resulting in death or serious injury.

NOTICE

?

When the windshield is dry
Do not use the wipers, as they may damage the windshield.

?

When the washer fluid tank is empty
Do not operate the switch continually as the washer fluid pump may over-
heat.

?

When a nozzle becomes blocked
In this case, contact your Toyota dealer.
Do not try to clear it with a pin or other object. The nozzle will be damaged.
