assistance during driving, for
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-

Opening the front doors establishes
the idle state, refer to page 43.
When the vehicle is locked, the
vehicle alarm system reacts to
the following changes:
• Opening a door, the hood or
the trunk lid.
• Movements in the car's inte- rior.
• Changes in the vehicle tilt, e. g., during attempts at stealing
a wheel or when towing the
vehicle.
• Disconnected battery voltage.
• Improper use of the socket for OBD Onboard Diagnosis.
• Locking the vehicle while a device is connected to the
socket for the OBD Onboard-
Diagnosis. For socket for the
OBD Onboard Diagnosis,
refer to page 302.
The alarm system signals the
following changes visually and
acoustically:
• Acoustic alarm: Depending on local regulations, the acoustic
alarm may be suppressed.
• Visual alarm: By flashing of the hazard warning system
and headlights, where
required. Do not modify the system to
ensure function of the alarm
system.
When you unlock and lock the
vehicle, either with the remote
control or with Comfort entry, the
alarm system is switched off and
on at the same time.
The alarm system is triggered
when a door is opened if the
door was unlocked using the
integrated key in the door lock.
Switching off the alarm, refer to
page 94.
The trunk lid can be opened
even when the alarm system is
switched on.
After the trunk lid is closed, it is
locked and monitored again pro-
vided the doors are locked. The
hazard warning system flashes
once.
You can trigger the alarm sys-
tem if you find yourself in a dan-
