 Maintenance system.
 "Owner's Warranty Informa-
tion Booklet" or "Owner's
Manual Supplement".
If the vehicle is not maintained
according to these specifica-
tions, this could result in serious
damage to the vehicle. Such
damage is not covered by the
warranty.
Data memory
General information
Electronic control devices are
installed in the vehicle. Elec-
tronic control units process data
they receive from vehicle sen-
sors, self-generate or exchange
with each other. Some control
units are necessary for the vehi-
cle to function safely or provide
assistance during driving, for
instance driver assistance sys-
tems. Furthermore, control
devices facilitate comfort or info-
tainment functions.
Information about stored or
exchanged data can be
requested from the manufac-
turer of the vehicle, in a sepa-
rate booklet, for example.
Personal reference
Each vehicle is marked with a
unique vehicle identification
number. Depending on the
Supra Owner's Manual
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.
Operating data in the vehi-
cle
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.
