Before driving
CAUTION
Observe the following precautions to reduce the risk of injury in the event of
emergency braking, sudden swerving or an accident.
Failing 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.
● 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 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.

68 1-7. Safety information
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 airbag s 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, and parts of the front and rear pillars, roof side
rail and rear roof headlining may be hot for several minutes. The airbag
itself may also be hot.
● The front windshield may crack.
■ Operating conditions (SRS front airbags)
●The SRS front airbags and SRS seat cushion airbags will deploy in the
event of an impact that exceeds the set threshold level (the level of force
corresponding to an approximately 12-18 mph [20-30 km/h] frontal colli-
sion 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.).
● Depending on the type of collision, it is possible that only the seat belt
pretensioners will activate.
● The SRS front airbags and seat cushion airbag for the front passenger
will not activate if there is no passenger sitting in the front passenger
seat. However, the SRS front airbags and seat cushion airbag for the
front passenger may deploy if luggage is put in the seat, even if the seat
is unoccupied. ( P. 79)

132 2-3. Operating the lights and wipers
Turning on the high beam headlightsWith the headlights on, push
the lever forward to turn on the
high beams.
Pull the lever back to the center
position to turn the high beams
off.
Pull the lever toward you to
turn on the high beams.
Release the lever to turn them off.
You can flash the high beams
with the headlights on or off.
■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.
● 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.

Automatic light off system (if equipped)
●When the headlights come on: The headlights and tail lights automati-
cally turn off after 30 seconds when a door is opened and closed with the
engine switch turned to the ACC or LOCK position. (The lights turn off
immediately if the button on the wireless remote control is pressed
after all doors are locked.)
● When only the tail lights come on: The tail lights turn off automatically
with the engine switch turned to the ACC or LOCK position and the
driver’s door is opened.
■ Customization that can be configured at Scion dealer
Settings of the light sensor sensitivity can be changed.
(Customizable features P. 339)
NOTICE
■To prevent battery discharge
Do not leave the lights on longer than necessary when the engine is not run-
ning.

5-2. Steps to take in an emergency
*3:Front passenger’s seat belt reminder:
The front passenger’s seat belt reminder sounds to alert the front passenger
that his or her seat belt is not fastened. The buzzer sounds intermittently for
approximately 10 seconds after the vehicle has reached a speed of at least
12 mph (20 km/h). Then, if the seat belt is still unfastened, the buzzer will
sound in a different tone for approximately 20 more seconds.
*4: 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, rear airbag sensors, driver’s seat position sensor, driver’s seat belt
buckle switch, front passenger occupant classification system (ECU and
sensors), AIR BAG ON indicator light, AIR BAG OFF indicator light, front
passenger’s seat belt buckle switch, seat belt pretensioner assemblies, air-
bags, interconnecting wiring and power sources. ( P. 275)
■ Key reminder buzzer
The buzzer indicates that the key has not been removed with the engine
switch in the ACC or LOCK position and the driver’s door opened.
■ Electric power steering system warning light
When the battery charge becomes insufficient or the voltage temporarily
drops, the electric power steering system warning light may comes on.
■ 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 several driving trips.
If the malfunction indicator lamp does not go off even after several trips, con-
tact your Scion dealer as soon as possible.

280 5-2. Steps to take in an emergency
■Front passenger detect ion sensor and passenger seat belt reminder
● If luggage or other load is placed on the front passenger seat, depending
on its weight, the reminder light to flash and buzzer to sound.
● If a cushion is placed on the seat, the sensor may not detect a passen-
ger, and the warning light may not operate properly.
■
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 does not turn off the tire
pressure warning light.
■The tire pressure warning light ma y turn on due to natural causes
The tire pressure warning light may turn on due to natural causes such
as natural air leaks or tire inflation pressure changes caused by temper-
ature. In this case, adjusting the ti re inflation pressure will turn off the
warning light (after a few minutes).
■If the tire pressure warning system is inoperative
The tire pressure warning system will be disabled in the following condi-
tions:
(When the condition becomes normal, the system will work properly.)
●If tires not equipped with tire pressure warning valves and transmit-
ters are used.
●If the ID code on the tire pressure warning valves and transmitters is
not registered in the tire pressure warning computer.
●If the tire inflation pressure is 73 psi (500 kPa, 5.1 kgf/cm2 or bar) or
higher.
The tire pressure warning system may be disabled in the following condi-
tions:
(When the condition becomes normal, the system will work properly.)
●If electronic devices or facilities using similar radio wave frequencies
are nearby.
●If a radio set at similar frequencies is in use in the vehicle.
●If a window tint that affects the radio wave signals is installed.
●If there is a lot of snow or ice on the vehicle, in particular around the
wheels or wheel housings.
