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

■Battery-saving function
In the following circumstances, the entry function is disabled in order to pre-
vent the vehicle battery from discharging and the electronic key battery from
discharging.
● When the entry function has not been used for 5 days or more
● When the electronic key has been left within approximately 6 ft. (2 m) of
the vehicle for 10 minutes or more
● If the entry function has not been used for 14 days or more, the vehicle
cannot be unlocked by a door other than the driver’s door. To unlock the
vehicle, grip the driver’s door handle or use the wireless remote control
or the mechanical key.
The system will resume operation when...
● The vehicle is locked using the lock sensor when carrying the electronic
key on your person.
● The vehicle is locked/unlocked using the wireless remote control. 
( P. 5 0 )
● The vehicle is locked/unlocked using the mechanical key. ( P. 400)

Notes for locking the doors
● Touching the door lock sensor while wearing gloves may delay or prevent
lock operation. Remove the gloves and touch the lock sensor again.
● When the lock operation is performed using the lock sensor, recognition
signals will be shown up to two consecutive times. After this, no recogni-
tion signals will be given.
● If the door handle becomes wet while the electronic key is within the
effective range, the door may lock and unlock repeatedly. Place the key
in a position 6 ft. (2 m) or more separate from the vehicle while the vehi-
cle is being washed. (Take care to ensure that the key is not stolen.)
● If the electronic key is inside the vehicle and a door handle becomes wet
during a car wash, a buzzer will sound outside the vehicle. To turn off the
alarm, lock all the doors.
● The lock sensor may not work properly if it comes into contact with ice,
snow, mud, etc. Clean the lock sensor and attempt to operate it again, or
use the lock sensor on the lower part of the door handle.

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 severe 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_tC_U_(OM21041U)
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 ai rbag 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 restrain the motion
of the occupants.
■ 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, parts of the front and rear pillars, and roof side
rails, may be hot for several minutes. The airbag itself may also be hot.
● The windshield may crack.

118 1-7. Safety information
Scion_tC_U_(OM21041U)
CAUTION
■SRS airbag precautions
● 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 airbags have 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 Scion 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
passenger airbag may not deploy in the event of a collision.
