The SRS side airbags and curtain shield
airbags are generally not designed to
inflate if the vehicle is involved in a
front or rear collision, if it rolls over,
or if it is involved in a lowspeed side
collision.

The SRS side airbag and curtain shield
airbag system consists mainly of the fol-
lowing components, and their locations are
shown in the illustration. 1. Curtain shield airbag modules (airbag and inflator)
2. SRS warning light
3. “AIR BAG ON” and “AIR BAG OFF” indicator lights
4. Front passenger occupant classification system (ECU and sensors)
5. Front passenger ’s seat position sensor (for side airbags)
6. Side airbag modules (airbag and inflator) 7. Curtain shield airbag sensors
8. Side and curtain shield airbag sensors
9. Front passenger ’s seat belt buckle
switch
10. Airbag sensor assembly

The SRS side airbag and curtain shield
airbag system is controlled by the airbag
sensor assembly. The airbag sensor as-
sembly consists of a safing sensor and
airbag sensor.
In a severe side impact, the side and
curtain shield airbag sensor and/or the
curtain shield airbag sensor trigger(s) the
side airbag inflators and/or the curtain
shield airbag inflators. At this time a
chemical reaction in the inflators quickly
fills the airbags with non −toxic gas to help
restrain the lateral motion of the occu-
pants.
When the airbags inflate, they produce a
fairly loud noise and release some smoke
and residue along with non −toxic gas. This
does not indicate a fire. This smoke may
remain inside the vehicle for some time,
and may cause some minor irritation to
the eyes, skin or breathing. Be sure to
wash off any residue as soon as possible
to prevent any potential skin irritation with
soap and water. If you can safely exit
from the vehicle, you should do so imme-
diately. Deployment of the airbags happen in a
fraction of a second, so the airbags must
inflate with considerable force. While the
system is desi
gned to reduce serious inju-
ries, it may also cause minor burns or
abrasions and swelling.
Front seats as well as parts of the front
and rear pillars, and roof side rail may be
hot for several minutes, but the airbags
themselves will not be hot. The airbags
are designed to inflate only once.
CAUTION
SRS side airbags and curtain shield
airbags inflate with considerable
force. To reduce the possibility of
death or serious injury when they in-
flate, the driver, front passenger and
rear outside passengers must:
Wear their seat belts properly.
Remain properly seated with their
backs upright and against the seats
at all times.
Do not allow anyone to lean against
the door when the vehicle is in use,
since the side airbag and curtain
shield airbag could inflate with con-
siderable speed and force. Other-
wise, he/she may be killed or seri-
ously injured. Special care should
be taken especially when you have
a small child in the vehicle.

“ON” position, the light does not come
on or remains on for more than about
6 seconds or flashes.
The light comes on or starts flashing
while you are driving.
The SRS warning light and “AIR BAG
OFF” indicator light will come on if there
is a malfunction in the front passenger
occupant classification system.
(l) Electric Power Steering System Warning Light
The light comes on when the ignition key
is turned to the “ON” positron. If the elec-
tric power steering system warning light
works properly, the light turns off after a
few seconds. If the system has malfunc-
tions, the light comes on again. If the following conditions occur, this
indicates a malfunction somewhere in
the components monitored by the warn-
ing light system. Contact your Scion
dealer as soon as possible to service
the vehicle.
The light does not come on when the
ignition key is turned to the “ON” posi-
tion or remains on.
The light stays on while you are driv-
ing.
CAUTION
If the electric power steering system
warning light comes on, take your ve-
hicle to Scion dealer as soon as pos-
sible. In this case, more effort is re-
quired for the steering wheel to turn
than usual. Drive your vehicle while
firmly gripping the steering wheel.

The displayed values in the multi−informa-
tion display indicate general driving condi-
tions. Accuracy varies with driving habits
and road conditions.
When the ignition switch is on, the last
previously used mode displayed just be-
fore the ignition switch is off will appear.
If the electrical power source has been
disconnected from the multi −information
display, the display will automatically be
set to the initial mode.
When the headlight switch is turned on,
the brightness of the display will be re-
duced.
You can adjust the brightness of the dis-
play. To adjust the brightness, see “Instru-
ment panel light control” on page 90.
CAUTION
Do not operate the switches while the
vehicle is moving. Make sure to oper-
ate the switches when the vehicle is
stopped.
1. Clock
To adjust the clock, the key must be in
the “ON” position and the vehicle must be
stopped.
Pushing the “DISP” switch flashes the in-
dicator for the minute and you can adjust
the minute.
Press the “DISP” switch until the desired
minute will appear.
After 5 or more seconds pass without op-
erating, the indicator for the hour flashes.
Then you can adjust the hour.
Press the “DISP” switch until the desired
hour will appear.
After 5 or more seconds pass without op-
erating, the indicator will return to the nor-
mal display.
If quick adjustment to a full hour is de-
sired, push the “DISP” switch for 1 sec-
ond.
For example, if the “DISP” switch is de-
pressed when the time is between
1:01—1:29, the time will change to 1:00.
If the time is between 1:30—1:59, the
time will change to 2:00.
If the electrical power source has been
disconnected from the clock, the time dis-
play will automatically be set to 1:00. 2. Outside temperature display
(“C” or “ F”)
The display indicates between the range
of –30 C (–22 F) and 50 C (122 F).
Each time you push the “DISP” switch for
1 second, the display switches between
“  C” and “ F”.
If an abnormality exists in the connection
of the outside air temperature sensor, “––”
will appear on the display. If “––” appears,
contact your Scion dealer.
3. Instantaneous fuel consumption (“MPG”)
The instantaneous fuel consumption is
calculated and displayed based on dis-
tance and fuel consumption with the
engine running.
Note that an accurate figure may not be
shown in the following cases.
The vehicle is stopped with the engine
running. (The display will indicate the
extremely high fuel consumption.)
The vehicle is driving down a long
slope, applying the engine brake. (The
display will indicate the extremely low
fuel consumption.)
The calculation is reset when the ignition
switch is turned off.

When the antilock brake system is ac-
tivated, the following conditions may
occur. They do not indicate a malfunc-
tion of the system:
You may hear the anti−lock brake sys-
tem operating and feel the brake pedal
pulsating and the vibrations of the ve-
hicle body and steering wheel. You
may also hear the motor sound in the
engine compartment even after the ve-
hicle is stopped.
At the end of the anti −lock brake sys-
tem activation, the brake pedal may
move a little forward.
CAUTION
Do not overestimate the antilock
brake system: Although the antilock
brake system assists in providing ve-
hicle control, it is still important to
drive with all due care and maintain
a moderate speed and safe distance
from the vehicle in front of you, be-
cause there are limits to the vehicle
stability and effectiveness of steering
wheel operation even with the anti
lock brake system on.
If tire grip performance exceeds its
capability, or if hydroplaning occurs
during high speed driving in the rain,
the antilock brake system does not
provide vehicle control.
Antilock brake system is not de-
signed to shorten the stopping dis-
tance: Always drive at a moderate
speed and maintain a safe distance
from the vehicle in front of you.
Compared with vehicles without an
antilock brake system, your vehicle
may require a longer stopping dis-
tance in the following cases:
Driving on rough, gravel or snow
covered roads.
Driving with tire chains installed.
Driving over the steps such as the
joints on the road.
Driving on roads where the road
surface is pitted or has other differ-
ences in surface height.
Install all 4 tires of specified size at
appropriate pressure: The antilock
brake system detects vehicle speeds
using the speed sensors for respec-
tive wheels’ turning speeds. The use
of tires other than specified may fail
to detect the accurate turning speed
resulting in a longer stopping dis-
tance.
