Adjusting the height of rear view mirror
Adjust the height of the rear view
mirror by moving it up and down.
■To prevent sensor error (veh icles with auto anti-glare inside rear view
mirror)
CAUTION
■ Caution while driving
Do not adjust the position of the mirror while driving.
Doing so may lead to mishandling of the vehicle and cause an accident,
resulting in death or serious injury.
To ensure that the sensors operate prop-
erly, do not touch or cover them.

Before driving
SIENNA_OM_OM45483U_(U)
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.

■
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.
