certain data, such as:
• Engine speed
• Accelerator status
• Brake status
• Vehicle speed
• Shift position
The recorded data varies according to the vehicle grade level and options
with which it is equipped. These computers do not record conver sations or
sounds, and only record images outside of the vehicle in certai n situations.

Toyota may use the data recorded in these computers to diagnose malfunc-
tions, conduct research and development, and improve quality.
Toyota will not disclose the recorded data to a third party exc ept:
• With the consent of the vehicle owner or with the consent of the lessee if the vehicle is leased
• In response to an official request by the police, a court of l aw or a govern-
ment agency
• For use by Toyota in a lawsuit
• For research purposes where the data is not tied to a specific vehicle or
vehicle owner
●Usage of data collected through Safety Connect (U.S. mainland o nly)
If your Toyota has Safety Connect and if you have subscribed to those ser-
vices, please refer to the Safety Connect Telematics Subscription Service

The SRS airbag and seat belt pretensioner devices in your Toyota contain
explosive chemicals. If the vehicle is scrapped with the airbag s and seat belt
pretensioners left as they are, this may cause an accident such as fire. Be
sure to have the systems of the SRS airbag and seat belt preten sioner
removed and disposed of by a qualified service shop or by your Toyota dealer
before you scrap your vehicle.
Special handling may apply,
See www.dtsc.ca.gov/hazardouswaste/perchlorate.
Your vehicle has components that may contain perchlorate. These compo-
nents may include airbag, seat belt pretensioners, and wireless remote con-
trol batteries.

WARNING
■ General precautions while driving
Driving under the influence: Never drive your vehicle when unde r the influ-
ence of alcohol or drugs that have impaired your ability to operate your vehi-
cle. Alcohol and certain drugs delay reaction time, impair judg ment and
reduce coordination, which could lead to an accident that could result in
death or serious injury.
Defensive driving: Always drive defensively. Anticipate mistake s that other
drivers or pedestrians might make and be ready to avoid acciden ts.
Driver distraction: Always give your full attention to driving. Anything that
distracts the driver, such as adjusting controls, talking on a cellular phone or
reading can result in a collision with resulting death or serio us injury to you,
your occupants or others.
■ General precaution regar ding children’s safety
Never leave children unattended in the vehicle, and never allow children to
have or use the key.
Children may be able to start the vehicle or shift the vehicle into neutral.
There is also a danger that children may injure themselves by p laying with
the windows, the moon roof, or other features of the vehicle. In addition,
heat build-up or extremely cold temperatures inside the vehicle can be fatal
to children.

471-1. For safe use

For safety and security
■If the SRS airbags deploy (inflate)
●Slight abrasions, burns, bruising etc., may be sustained from S RS airbags,
due to the extremely high speed deployment (inflation) by hot g ases.
● Bruising and slight abrasions may result from contact with a de ploying
(inflating) SRS airbag.
● A loud noise and white powder will be emitted.
● Parts of the airbag module (steering wheel hub, airbag cover an d inflator) as
well as the front seats, parts of the front and rear pillars, a nd roof side rail,
may be hot for several minutes. The airbag itself may also be h ot.
● The windshield may crack.
● For Safety Connect subscribers, if the SRS airbags deploy or in the event of
a severe rear-end collision, the system is designed to send an emergency
call to the response center, notifying them of the vehicle’s location (without
needing to push the “SOS” button) and an agent will attempt to speak with
the occupants to ascertain the level of emergency and assistanc e required.
If the occupants are unable to communicate, the agent automatic ally treats
the call as an emergency and helps to dispatch the necessary em ergency
services. ( P. 385)
■ SRS airbag deployment condi tions (SRS front airbags)
● The SRS front airbags will deploy in the event of an impact tha t exceeds the
set threshold level (the level of force corresponding to an approximately 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 in the following
situations:
• If the vehicle strikes an object, such as a parked vehicle or sign pole,
which can move or deform on impact
• If the vehicle is involved in an underride collision, such as a collision in
which the front of the vehicle “underrides”, or goes under, the bed of a
truck
● Depending on the type of collision, it is possible that only th e seat belt pre-
tensioners will activate.
● The SRS front airbags for the front passenger will not activate if there is no
passenger sitting in the front passenger seat. However, the SRS front air-
bags for the front passenger may deploy if luggage is put in the seat, even if
the seat is unoccupied. ( P. 52)
● The SRS seat cushion airbag on the front passenger’s seat will not operate
if the occupant is not wearing a seat belt.

■Automatic Collision Notification
In case of either airbag deployme nt or severe rear-end collision, the
system is designed to automatically call the response center. T he
responding agent receives the v ehicle’s location and attempts to
speak with the vehicl e occupants to assess the level of emergency.
If the occupants are unable to communicate, the agent automati-
cally treats the call as an emergency, contacts the nearest eme r-
gency services provider to descr ibe the situation, and requests that
assistance be sent to the location.
■Stolen Vehicle Location
If your vehicle is stolen, Safety Connect can work with local author-
ities to assist them in locating and recovering the vehicle. Af ter filing
a police report, call the Safety Connect response center at 1-8 00-
331-4331 and follow the prompts for Safety Connect to initiate this
service.
In addition to assisting law enforcement with recovery of a sto len
