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-

The tire inflation pressure speci-

The corrected tire inflation pres-
sures are applied automatically.
Make sure that the correct tire
settings have been made.
With tires that cannot be found
in the tire pressure values on
the Control Display, reset the
Tire Pressure Monitor TPM.
Regularly check the tire inflation
pressure and correct it as
needed:
• At least twice a month.
• Before embarking on an extended trip. The friction during hard braking
may produce brake dust and
make the rims dirty. Brake dust
can be removed by cleaning the
rims. Toyota recommends using
vehicle care and cleaning prod-
ucts from Toyota.
Depending on the previous dis-
plays, the status display
appears when the engine is run-
ning or after the vehicle has
been driven for at least 30 min-
utes.

Safety information
WARNING
High gross weight can overheat
the tires, damage them internally
and cause a sudden drop in tire
inflation pressure. Driving charac-
teristics may be negatively
impacted, reducing lane stability,
lengthening the braking distances
and changing the steering
response. There is a risk of an
accident. Pay attention to the per-
mitted load capaci ty of the tires
and never exceed the permitted
gross weight.
WARNING
Loose object or devices with a
cable connection to the vehicle,
for instance mobile phones, can
be thrown about the car

2644-1. DRIVING TIPS
Additional weight increases fuel
consumption.
Attached parts on the vehicle
impair the aerodynamics and
increase the fuel consumption.
Open windows increase air
resistance and therefore lead to
greater fuel consumption.
Tires can affect consumption in
various ways, for instance tire
size may influence consump-
tion.
Check and, if needed, correct
the tire inflation pressure at least
twice a month and before start-
ing on a long trip.
Low tire inflation pressure
increases rolling resistance and
thus raises fuel consumption
and tire wear.Do not wait for the engine to
warm-up while the vehicle
remains stationary. Start driving
right away, but at moderate
engine speeds.
This is the quickest way of
warming the cold engine up to
operating temperature.
Driving smoothly and proactively
reduces fuel consumption.
Avoid unnecessary acceleration
and braking.
By maintaining a suitable dis-
tance to the vehicle driving
ahead of you.
Driving at low engine speeds
lowers fuel consumption and
reduces wear.
If necessary, observe the vehi-
cle's gear shift indicator, refer to
page 148.
When approaching a red light,
take your foot off the accelerator
and let the vehicle coast to a
halt.
For going downhill take your foot

The tire characteristics and tire
inflation pressure influence the
following:
• The service life of the tires.
• Road safety.
• Driving comfort.
• Fuel consumption.The tire inflation pressure table,
refer to page 273, contains all
tire inflation pressure specifica-
tions for the specified tire sizes
at the ambient temperature. The
tire inflation pressure values
apply to tire sizes approved by
the manufacturer of the vehicle
for the vehicle type.
To identify the correct tire infla-
tion pressure, please note the
following:
If the tire's speed code cannot
be found, then the tire inflation
pressure for the corresponding
tire size applies.
• Tire sizes of your vehicle.
• Maximum permitted driving
speed.

WARNING
A tire with too little or no tire infla-
tion pressure may heat up signifi-
cantly and sustain damage. This
will have a negative impact on
aspects of handling, such as
steering and braking response.
There is a risk of an accident.
Regularly check the tire inflation
pressure, and correct it as
needed, for instance twice a
month and before a long trip.

The current tire inflation pres-
sure values and the intended
tire inflation pressure values for
the mounted tires can be dis-
played on the Control Display.
To ensure that they are dis-
played correctly, the tire sizes
must be stored in the system
and must have been set, refer to
page 287, for the mounted tires.
The current tire inflation pres-
sure value is located on each
tire.
The reference tire inflation pres-
sure value is located in the
lower area of the Control Dis-
play.
Tires heat up while driving. The
tire inflation pressure increases
with the tire temperature.
Tires have a natural, consistent
loss of tire inflation pressure.
The displays of inflation devices
may under-read by up to 0.1
bar/2 psi.The tire inflation pressure speci-
fications in the tire inflation pres-
sure table only relate to cold
tires or tires at the same tem-
perature as the ambient tem-
perature.
Only check the tire inflation
pressure levels when the tires
are cold, i.e.:
• Driving range of max. 1.25
miles/2 km has not been
exceeded.
• If the vehicle has not moved again for at least 2 hours after
a trip.
Check the tire inflation pressure
of the emergency wheel in the
cargo area regularly, and correct
it as needed.
1 Determine, refer to page 270,
the intended tire inflation
pressure levels for the
mounted tires.
2 Check the tire inflation pres-
sure in all four tires, using a
pressure gauge, for example.
3 Correct the tire inflation pres-
sure if the actual tire inflation
pressure deviates from spec-
ified tire inflation pressure.
4 Check whether all valve caps
are screwed onto the tire
valves.
