Supra Owner's Manual
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 140.
When approaching a red light,
take your foot off the accelerator
and let the vehicle coast to a
halt.

This chapter describes all stan-
dard, country-specific and
optional features offered with
the series. It also describes fea-
tures and functions that are not
necessarily available in your
vehicle, e.g., due to the selected
options or country versions. This
also applies to safety-related
functions and systems. When
using these functions and sys-
tems, the applicable laws and
regulations must be observed.
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 260, 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.

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 274, for the mounted tires.
The current tire inflation pres-
sure value is located on each
tire.
The intended 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 258,
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 current tire infla-
tion pressure value deviates
from the specified value.
4 Check whether all valve caps
are screwed onto the tire
valves.

For each tire size, the manufac-
turer of the vehicle recommends
certain tire brands. The tire
brands can be identified by a
star on the tire sidewall.
Tire traction is not optimal due to
manufacturing circumstances
when tires are brand-new; they
achieve their full traction poten-
tial after a break-in time.
Drive conservatively for the first
200 miles/300 km.
The manufacturer of your vehi-
cle does not recommend the
use of retreaded tires.
Safety information
WA R N I N G
Wheels and tires which are not
suitable for your
vehicle can dam-
age parts of the vehicle, for
instance due to contact with the
body due to tolerances despite
the same official size rating.
There is a risk of an accident. The
manufacturer of your vehicle
strongly suggests that you use
wheels and tires that have been
recommended by the vehicle
manufacturer for your vehicle
type.
WA R N I N G
Mounted steel wheels can cause
technical problem s, for instance
independent loosening of the lug
bolts, damage to t he brake discs.
There is a risk of an accident. Do
not mount steel wheels.
WA R N I N G
Incorrect wheel/tire combinations
will have a negative impact on the
vehicle's handling and on the
function of a variety of systems,
such as the Anti-lock Brake Sys-
tem or Vehicle S tability Control
System. There is a risk of an acci-
dent. To maintain good handling
and vehicle response, use only
tires with a single tread configura-
tion from a single manufacturer.
The manufacturer of the vehicle
recommends that you use wheels
and tires that have been recom-
mended by the vehicle manufac-
turer for your vehicle type.
Following tire damage, have the
original wheel/tire combination
remounted on the vehicle as soon
as possible.

New tires
Retreaded tires
WA R N I N G
Retreaded tires can have different
tire casing structures. With
advanced age the service life can
be limited. There is a risk of an
accident. The manufacturer of
your vehicle does not recommend
the use of retreaded tires.

The following conditions must
be met for the system; other-
wise, reliable flagging of a loss
of tire inflation pressure is not
assured:
• After each tire or wheel change, the system detects
and updates the mounted
tires and displays them after a
short trip on the Control Dis-
play.
Enter the information about the
mounted tires in th e tire settings
when the system does not automat-
ically detect the tires.
• For tires with special
approval:
• After a tire or wheel replacement, a reset was performed with the
correct tire inflation pressure.
• After the tire inflation pressure was adjusted to a new value, a
reset was performed.
• Wheels with TPM wheel elec-
tronics.
The information about the
mounted tires can be entered in
the tire settings if the system
does not automatically detect
the tires.
The tire sizes of the mounted
tires can be gathered from the
tire inflation pressure details on
the vehicle, refer to page 258, or
directly on the tires.
The tire details do not need to
be re-entered when the tire infla-
tion pressure is corrected.
For summer and winter tires, the
tire details entered last are
stored. After a tire or wheel
replacement, the settings of the
tire sets used last can be
selected.

The display of the target pres-
sures is not a sub
stitute for the
tire inflation pressure details on
the vehicle. Incorrect entries in
the tire settings can lead to incor-
rect target tire inflation pressure
values. In this case, it cannot be
guaranteed that the notification of
a loss of tire inflation pressure will
be reliable. There is a risk of injury
and risk of damage to property.
Ensure that the tire sizes of the
mounted tires are displayed cor-
rectly and match the details on the
tires and on the vehicle.
