CAUTION
■Wearing a seat belt
●Do not recline the seat any more than necessary to achieve a proper seat-
ing position. The seat belt is most effective when the occupants are sitting
up straight and well back in the seats.
● Do not wear the shoulder belt under your arm.
● Always wear your seat belt low and snug across your hips.
■ When children are in the vehicle
Do not allow children to play with the seat belt. If the seat belt becomes
twisted around a child’s neck, it may lead to choking or other serious injuries
that could result in death. If this occurs and the buckle cannot be unfas-
tened, scissors should be used to cut the belt.
■ Adjustable shoulder anchor
Always make sure the shoulder belt is positioned across the center of your
shoulder. The belt should be kept away from your neck, but not falling off
your shoulder. Failure to do so could reduce the amount of protection in an
accident and cause death or serious injuries in the event of a sudden stop,
sudden swerve or accident. ( P. 79)
■ Seat belt pretensioners
●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 seat belt
pretensioner for the front passenger’s seat may not activate in the event of
a collision.
● If the pretensioner has activated, the SRS warning light will come on. In
that case, the seat belt cannot be used again and must be replaced at
your Toyota dealer.
■ Seat belt damage and wear
●Do not damage the seat belts by allowing the belt, plate, or buckle to be
jammed in the door.
● Inspect the seat belt system periodically. Check for cuts, fraying, and loose
parts. Do not use a damaged seat belt until it is replaced. Damaged seat
belt cannot protect an occupant from death or serious injury.

Before driving
Adjusting the height of rear view mirror
Adjust the height of the rear view
mirror by moving it up and down.
Auto anti-glare inside rear view mirror
In automatic mode, sensors are used to detect the headlights of
vehicles behind and automatical ly reduces the reflected light.
Turns automatic mode ON/
OFF
The indicator comes on when
automatic mode is turned on.
The mirror will revert to the
automatic mode each time the
engine switch is turned on.

CAUTION
■Caution while driving
Do not adjust the position of the mirror while driving.
Doing so may lead to mishandling of the vehicle and an accident, resulting in
death or serious injury.
To ensure that the sensors operate prop-
erly, do not touch or cover them.
Hold and rotate the mirror to adjust the
support.

Alarm
: If equipped
The system sounds the alarm and flashes lights when forcible entry
is detected.
■ Triggering of the alarm
The alarm is triggered in the fo llowing situations when the alarm
is set.
● A locked door is unlocked or opened in any way other than
using the wireless remote control door lock function or key.
(The doors will lock again automatically.)
● The hood is opened.
● Vehicles with the glass breakage sensor (if equipped): The
side windows are tapped or broken.
● The battery is reconnected.
■ Setting the alarm system
Close the doors and hood,
and lock all the doors. The
system will be set automati-
cally after 30 seconds.
The indicator light changes
from being on to flashing when
the system is set.
■Deactivating or stopping the alarm
Do one of the following to deactivate or stop the alarm.
●Unlock the doors.
● Turn the engine switch to the ACC or ON position, or start the
engine.
(The alarm will be deactivated or stopped after a few sec-
onds.)

124 1-7. Safety information
Your vehicle is equipped with ADVANCED AIRBAGS designed based
on US motor vehicle safety standards (FMVSS208). The airbag sys-
tem controls airbag deployment power for the driver and right front
passenger. The driver airbag system consists of the driver seat’s
position sensor etc. The front pass enger’s airbag system consists of
the front passenger occupant classification sensor etc.
The main SRS airbag system components are shown above. The
SRS airbag system is controlled by the airbag sensor assembly. The
airbag sensor assembly consists of a safing sensor and an airbag
sensor.
Front bench type seat: The SRS airbags are designed to protect the
driver and right front passenger, and they are not designed to protect
an occupant in the front center seating position.
In certain types of severe frontal or side impacts, the SRS airbag sys-
tem triggers the airbag inflators. A chemical reaction in the inflators
quickly fills the airbags with non-toxic gas to help restrain the motion
of the occupants. Side airbags

SRS warning light
This warning light system monitors the airbag sensor assembly, front airbag
sensors, side and curtain shield airbag sensor assemblies, curtain shield air-
bag sensor assemblies, driver’s seat position sensor, driver’s seat belt
buckle switch, front passenger occupant classification system, AIR BAG ON
and AIR BAG OFF indicator lights, front passenger’s seat belt buckle switch,
front seat belt pretensioner assemblies , RSCA OFF indicator light, inflators,
interconnecting wiring and power sources. ( P. 610)
■ If the SRS airbags deploy (inflate)
●Bruising and slight abrasions may result from contact with a deploying
(inflating) SRS airbag.
● A loud noise and white powder will be emitted.
● Parts of the airbag module (steering wheel hub, airbag cover and inflator)
as well as the front seats, and parts of the front and rear pillars and roof
side rail, may be hot for several minutes. The airbag itself may also be
hot.
● The front windshield may crack.
■ Operating conditions (front airbags)
●The SRS front airbag will deploy in the event of an impact that exceeds
the set threshold level (the level of force corresponding to an approxi-
mately 12-18 mph [20-30 km/h] frontal collision with a fixed wall that does
not move or deform).
However, this threshold velocity will be considerably higher if the vehicle
strikes an object, such as a parked vehicle or sign pole, which can move or
deform on impact, or if the vehicle is involved in an underride collision (e.g.
a collision in which the front of the vehicle “underrides”, or goes under, the
bed of a truck, etc.).
● It is possible that in some collisions where the forward deceleration of the
vehicle is very close to the designed threshold level, the SRS front air-
bags and the seat belt pretensioners may not activate together.
● The SRS front passenger airbag will not activate if there is no passenger
sitting in the right front passenger seat. However, the front passenger air-
bag may deploy if luggage is put in the seat, or the seat belt is fastened,
even if the seat is unoccupied. ( P. 135)

■ Daytime running light system (if equipped)
●To make your vehicle more visible to other drivers, the front turn signal
lights turn on automatically whenever the engine is started and the park-
ing brake is released. Daytime running lights are not designed for use at
night.
● 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 (vehicles with automatic light control system)
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.

Rear corner sensors
Front corner sensors
■ Intuitive parking assist switch
Press the switch to turn on.
(To turn off, press the switch
again.)
When on, the buzzer sounds
to inform the driver that the
system is operational. At this
time, the indicator will come
on.
