Your vehicle is equipped with
ADVANCED AIRBAGS designed based
on the US motor vehicle safety standards (FMVSS208). The airbag
sensor assembly (ECU) controls ai rbag deployment based on infor-
mation obtained from the sensors etc. shown in the system compo-
nents diagram above. This inform ation includes crash severity and
occupant information. As the air bags deploy, a chemical reaction in
the inflators quickly fills the airbags with nontoxic gas to help restrain
the motion of the occupants.

CAUTION
■
SRS airbag precautions
●Do not hang coat hangers or other hard objects on the coat hooks. All of
these items could become projectiles and may cause death or serious
injury, should the SRS curtain shield airbags deploy.
● If a vinyl cover is put on the area where the SRS knee airbag will deploy,
be sure to remove it.
● Do not use seat accessories which cover the parts where the SRS side
airbags inflate as they may interfere with inflation of the airbags. Such
accessories may prevent the side airbags from activating correctly, disable
the system or cause the side airbags to inflate accidentally, resulting in
death or serious injury.
● Do not strike or apply significant levels of force to the area of the SRS air-
bag components.
Doing so can cause the SRS airbags to malfunction.
● Do not touch any of the component parts immediately after the SRS air-
bags have deployed (inflated) as they may be hot.
● If breathing becomes difficult after the SRS airbag has deployed, open a
door or window to allow fresh air in, or leave the vehicle if it is safe to do
so. Wash off any residue as soon as possible to prevent skin irritation.
● If the areas where the SRS airbags are stored, such as the steering wheel
pad and front and rear pillar garnishes, are damaged or cracked, have
them replaced by your Toyota dealer.
● Do not place anything, such as a cushion, on the front passenger’s seat.
Doing so will disperse the passenger’s weight, which prevents the sensor
from detecting the passenger’s weight properly. As a result, the SRS front
airbags for the front passenger may not deploy in the event of a collision.

■Daytime running light system (if equipped)
●To make your vehicle more visible to other drivers, the headlights turn on
automatically (at a reduced intensity) whenever the engine is started and
the parking brake is released. Daytime running lights are not designed for
use at night.
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 (if equipped)
The sensor may not function properly if
an object is placed on the sensor, or any-
thing 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.

■Customization that can be configured at Toyota dealer or by the multi-
information display
Settings (e.g. light sensor sensitivity) can be changed.

NOTICE
■To prevent battery discharge
Do not leave the lights on longer than necessary when the engine is not run-
ning.

Automatic High Beam
: If equipped
The Automatic High Beam uses an in-vehicle camera sensor to
assess the brightness of streetligh ts, the lights of oncoming and
preceding vehicles, etc., and automatically turns high beam on or off
as necessary.
■ Activating the Automatic High Beam system
Push the lever away from you
with the headlight switch in the position when the
engine switch is in the “ON”
position (vehicles without a
smart key system) or the
“ENGINE START STOP”
switch is in IGNITION ON
mode (vehicles with a smart
key system).
The Automatic High Beam indi-
cator will come on when the
headlights are turned on auto-
matically to indicate that the
system is active.

■Limitations of the Automatic High Beam
Do not rely on the Automatic High Beam. Always drive safely, taking care to
observe your surroundings and turning high beam on or off manually if nec-
essary.
■ 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 pedestri-
ans 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 inside rear view mirror or ca mera 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 Automatic High Beam indicator is flashing.
• 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 distress to other drivers or pedestrians nearby.

■If the Automatic High Beam indicator flashes...
It may indicate a malfunction in the system. Contact your Toyota dealer.
■ Customization that can be configured at Toyota dealer or by the multi-
information display
The Automatic High Beam can be turned off.
(Customizable features: P. 828)
■ Temporary lowering sensor sensitivity
The sensitivity of the sensor can be temporarily lowered.
To lower the sensitivity, push and hold on the inside rear view mirror
for 15 to 20 seconds, and release. The indicator light on the inside rear view
mirror will flash to indicate that the sensitivity has been lowered.
Vehicles without a smart key system:
When the engine switch is turned to the “LOCK” position, the sensitivity will
be returned to its normal level.
Vehicles with a smart key system:
When the “ENGINE START STOP” switch is turned off, the sensitivity will be
returned to its normal level.

● Do not install a parking tag or any other accessories near or around the
inside rear view mirror and the camera sensor.
● Do not overload the vehicle.
● Do not modify the vehicle.
● Do not replace windshield with a non-genuine windshield.
