Event data recorder
Your vehicle has computers that monitor and control certain aspects of your
vehicle. These computers assist in driving and maintaining optimal vehicle
performance.
Besides storing data useful for troubleshooting, there is an event data
recorder (EDR) that records data in a crash or near crash event.
The SRS airbag sensor assembly contains the EDR. In a crash or near crash
event, this device may record the following information:
• Engine speed
• Whether the brake pedal was depressed or not
• Vehicle speed
• To what extent the accelerator pedal was depressed
• The transmission shift position
• Whether the driver and front passenger wore seat belts or not
• Driver’s seat position
• SRS airbag deployment data
• SRS airbag system diagnostic data
• Front passenger’s occupant classification
The information above is intended to be used for the purpose of improving
vehicle safety performance. Unlike general data recorders, the EDR does
not record sound data such as conversation between passengers.
●Disclosure of the EDR data
Scion will not disclose the data recorded in an EDR to a third party except
when:
• An agreement from the vehicle’s owner (or the leasing company for a leased vehicle) is obtained
• Officially requested to by the police or other authorities
• Necessary, for use as a defense for Scion in a lawsuit
• Ordered to by a court of law
However, if necessary, Scion will:
• Use the data for research on Scion vehicle safety performance
• Disclose the data to a third party for research purposes without disclosing details of the vehicle owner, and that only when deemed necessary
• Disclose summarized data cleared of vehicle identification information to a
non-Scion organization for research purposes

CAUTION
Observe the following precautions to reduce the risk of injury in the event of
sudden braking, sudden swerving or an accident.
Failure to do so may cause death or serious injury.
■Wearing a seat belt
● Ensure that all passengers wear a seat belt.
● Always wear a seat belt properly.
● Each seat belt should be used by one person only. Do not use a seat belt
for more than one person at once, including children.
● Scion recommends that children be seated in the rear seat and always
use a seat belt and/or an appropriate child restraint system.
● To achieve a proper seating position, do not recline the seat more than
necessary. 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 unfastened, scissors should be used
to cut the belt.
■ 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 Scion dealer.

Before driving
Scion_xB_U_(OM12F39U)
Your vehicle is equipped with
ADVANCED AIRBAGS designed based
on the US motor vehicle safety standards (FMVSS208). The airbag
system controls airbag deployment power for the driver and front pas-
senger. The driver airbag system cons ists of the driver’s seat position
sensor etc. The front passenger’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.
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 rest rain the motion
of the occupants.

5-2. Steps to take in an emergency
Scion_xB_U_(OM12F39U)
*1: Driver’s seat belt buzzer:
The driver’s seat belt buzzer sounds to alert the driver that his or her seat
belt is not fastened. Once the engine switch is turned to the “ON” or
“START” position, the buzzer sounds for 5 seconds. If the vehicle reaches a
speed of 12 mph (20 km/h), the buzzer sounds intermittently for 10 seconds.
Then, if the seat belt is still unfastened, the buzzer will sound in a different
tone for 20 more seconds.
*2: Front passenger’s seat belt buzzer:The front passenger’s seat belt buzzer sounds to alert the front passenger
that his or her seat belt is not fastened. The buzzer sounds intermittently for
10 seconds after the vehicle reaches a speed of 12 mph (20 km/h). Then, if
the seat belt is still unfastened, the buzzer will sound in a different tone for
20 more seconds.
*3: Refer to the separate “Scheduled Maintenance Guide” or “Owner’s ManualSupplement” for the maintenance interval applicable to your vehicle.
■ SRS warning light
This warning light system monitors the airbag sensor assembly, front airbag
sensors, side and curtain shield airbag sensors, curtain shield airbag sen-
sors, driver’s seat position sensor, driver’s seat belt buckle switch, front pas-
senger occupant classification system, “AIR BAG ON” indicator light, “AIR
BAG OFF” indicator light, front passenger’s seat belt buckle switch, seat belt
pretensioner assemblies, inflators, interconnecting wiring and power
sources. ( P. 6 9 )

296 5-2. Steps to take in an emergency
Scion_xB_U_(OM12F39U)
■Front passenger detection sensor, passenger seat belt reminder and
warning buzzer
● If luggage is placed on the front passenger seat, the front passenger
detection sensor may cause the warning light to flash and the warning
buzzer to sound even if a passenger is not sitting in the seat.
● If a cushion is placed on the seat, the sensor may not detect a passen-
ger, and the warning light may not operate properly.
■ If the malfunction indicator lamp comes on while driving
First check the following:
● Is the fuel tank empty?
If it is, fill the fuel tank immediately.
● Is the fuel tank cap loose?
If it is, tighten it securely.
The malfunction indicator lamp will go off after taking driving trips.
If the malfunction indicator lamp does not go off even after several trips, con-
tact your Scion dealer as soon as possible.
■
When the tire pressure warning light comes on
Check the tire inflation pressure and adjust to the appropriate level.
Pushing the tire pressure warning reset switch will not turn off the tire
pressure warning light.
■The tire pressure warning light may come on due to natural causes
The tire pressure warning light may come on due to natural causes such
as natural air leaks and tire inflat ion pressure changes caused by tem-
perature. In this case, adjusting the tire inflation pressure will turn off the
warning light (after a few minutes).
■When a tire is replaced with a spare tire
The compact spare tire is not equipped with a tire pressure warning
valve and transmitter. If a tire goes flat, the tire pressure warning light will
not turn off even though the flat tire has been replaced with the spare
tire. Replace the spare tire with the re paired tire and adjust the tire infla-
tion pressure. The tire pressure wa rning light will go off after a few min-
utes.
