instance driver assistance sys-
tems. Furthermore, control units
facilitate comfort or infotainment
functions.
Information about stored or
exchanged data can be
requested from the manufac-
turer of the vehicle, in a sepa-
rate booklet, for example.
Each vehicle is marked with a
unique vehicle identification
number. Depending on the
country, the vehicle owner can
be identified with the vehicle
identification number, license
plate and corresponding authori-
ties. In addition, there are other
options to track data collected in
the vehicle to the driver or vehi-
cle owner, e.g. via the Toyota
Supra Connect account that is
used.
Control units process data to
operate the vehicle.
For example, this includes:
• Status messages for the vehi-
cle and its Customize compo-
nents, e.g., wheel rotational
speed, wheel speed, deceler-
ation, transverse acceleration,
engaged safety belt indicator.
• Ambient conditions, e.g., tem-perature, rain sensor signals.
The processed data is only pro-
cessed in the vehicle itself and
generally volatile. The data is
not stored beyond the operating
period.
Electronic components, e.g.
control units and ignition keys,
contain components for storing
technical information. Informa-
tion about the vehicle condition,
component usage, mainte-
nance requirements or faults
can be stored temporarily or
permanently.
This information generally
records the state of a compo-
nent, a module, a system, or the
environment, for instance:
• Operating states of system
components, e.g., fill levels,
tire inflation pressure, battery
status.
• Malfunctions and faults in
important system compo-
nents, for instance lights and
brakes.
• Responses by the vehicle to
special situations such as air-
bag deployment or engage-
ment of the driving stability
control systems.
• Information on vehicle-dam-
aging events.
The data is required to perform
the control unit functions. Fur-
thermore, it also serves to rec-
ognize and correct malfunctions,
and helps the vehicle manufac- Personal reference

1Depress the brake pedal.
2Press the Start/Stop button.
The ignition is activated auto-
matically for a brief time and is
stopped as soon as the engine
starts.
Most of the indicator/warning
lights in the instrument cluster
light up for a varied length of
time.Depending on the engine condi-
tion, the full drive power may not
be available for approximately
30 seconds after starting the
engine. In this case, the vehicle
will not accelerate as usual.
READY in the instrument cluster
indicates that drive-ready state
is switched on.

Do not hang pieces of cloth-
ing, such as jackets, over the
backrests.
Never modify either the indi-
vidual components or the wir-
ing in the airbag system. This
also applies to steering wheel
covers, the dashboard, and
the seats.
Do not remove the airbag sys-
tem.
Even when you follow all
instructions very closely, injury
from contact with the airbags
cannot be fully ruled out in cer-
tain situations.
The ignition and inflation noise
may lead to short-term and, in
most cases, temporary hearing
impairment in sensitive occu-
pants.
Vehicle modifications for a per-
son with disabilities may affect
the air bag system; contact the
Toyota dealer for further infor-
mation.
Warnings and information on the
airbags are also found on the
sun visors.Functional readiness of

Safety information
WA R N I N G
Individual components can be hot
after triggering of the airbag sys-
tem. There is a risk of injury. Do
not touch individual components.
WA R N I N G
Improperly executed work can
lead to failure, malfunction or
unintentional triggering of the air-
bag system. In the case of a mal-
function, the airbag system might
not trigger as intended despite the
accident severity. There is a risk
of injuries or danger to life. Have
the airbag system checked,
repaired, dismantled and
scrapped by your Toyota dealer.
Display in the instrument
cluster
When drive-ready state is
switched on, the warning
light in the instrument
cluster lights up briefly and
thereby indicates the func-
tion readiness of the entire
airbag system and the belt
tensioners.
Malfunction
Warning light does not
come on when
drive-ready state is
switched on.
The warning light lights
up continuously.

The airbags are not designed to
be used in place of the seat
belts.
The SRS front airbags and SRS
knee airbags are designed to
supplement the seat belts, not
be used in place of them, to
increase their effectiveness as
an occupant protection device.
SRS is an acronym for Supplemen-
tal Restraint System
In the event of a collision, the
seat belts restrain the occupants
in their seats, but if the impact of
the collision is especially
severe, there is danger of an
occupant’s head and chest con-
tacting the steering wheel, dash-
board and windshield. In this
case, the SRS front airbags and
SRS knee airbags deploy
(inflate), instantly creating an air
cushion to help reduce the
impact on the occupants and
restrain them from contacting
the steering wheel, etc. with
their head, chest and knees.
The SRS front air bags and SRS
knee airbags deploy only when
an impact exceeding a certain
threshold is detected. In a colli-
sion, even if the impact is
severe enough to cause the
vehicle body to deform, the SRS airbags may not deploy if the
impact of the collision is suffi-
ciently dispersed by the crash
structures of the vehicle body. If
the force of the collision does
not cause the airbags to deploy,
the seatbelts will protect the
occupants.
When an airbag deploys, as it
will inflate nearly instantly, it may
impact an occupant and cause
an injury, or the loud noise emit-
ted by ignition or deployment
may cause temporary partial
loss of hearing. Also, as an air-
bag and nearby parts will be
extremely hot after the airbag
deploys, touching them may
cause burns. For these reasons,
deployment of the airbags is not
entirely risk free. Therefore, in
order to reduce this risk, the air-
bags are designed to only
deploy when additional reduc-
tion of the impact applied to the
occupants in a collision is nec-
essary. SRS front airbag/SRS knee

The SRS side airbags and SRS
curtain shield airbags are

when a severe impact is applied
to the side of the vehicle.
In the event of a side collision,
the SRS side airbag and SRS
