MOBILITY
Winter and all-season tires with
better cold weather performance
than summer tires.
Do not drive with a tire tread of
less than 0.12 in/3 mm, other-
wise there is an increased risk
of hydroplaning.
Do not drive with a tire tread of
less than 0.16 in/4 mm, as such
tires are less suitable for winter
operation. Wear indicators are distributed
around the tire's circumference
and have the legally required
minimum height of 0.063
inches/1.6 mm.
The positions of the wear indica-
tors are marked on the tire side-
wall with TWI, Tread Wear
Indicator.
Inspect your tires regularly for
damage, foreign objects lodged
in the tread, and tread wear.
Driving over rough or damaged
road surfaces, as well as debris,
curbs and other obstacles can
cause serious damage to
wheels, tires and suspension
parts. This is more likely to
occur with low-profile tires,
which provide less cushioning
between the wheel and the
road. Be careful to avoid road
hazards and reduce your speed,
especially if your vehicle is
WARNING
The temperature grade for this tire
is established for a tire that is
properly inflated and not over-
loaded. Excessive speed, under-
inflation, or excessive loading,
either separately or in combina-
tion, can cause heat buildup and
possible tire failure.

Supra Owner's Manual
Winter tires are recommended
for operating on winter roads.
Although so-called all-season
M+S tires provide better winter
traction than summer tires, they
usually do not provide the same
level of performance as winter
tires.
If the maximum speed of the
vehicle is higher than the per-
missible speed for the winter
tires, then attach a label show-
ing the permissible maximum
speed in the field of view. The
label is available from your Toy-
ota dealer.
With winter tires mounted,
observe and do not exceed the
permissible maximum speed.Do not exceed the maximum tire
inflation pressure indicated on
the side wall of the tire.
Store wheels and tires in a cool,
dry and dark place.
Always protect tires against all
contact with oil, grease, and sol-
vents.
Do not leave tires in plastic
bags.
Remove dirt from wheels or
tires.
• Park the vehicle as far away
as possible from passing traf-
fic and on solid ground.
• Switch on the hazard warning system.
• Secure the vehicle against rolling away by setting the
parking brake.
• Turn the steering wheel until the front wheels are in the
straight-ahead position and
engage the steering wheel
lock.
• Have all vehicle occupants get out of the vehicle and

WARNING
Rotating tires bet ween the axles
on vehicles with different tire sizes
or rim sizes on the front and rear
axles can cause damage to the
tires and the vehicle. There is a
risk of accident. D o not rotate the
tires between the axles on vehi-

sizes on the front and rear axles.

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 266, 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.

Safety information
WARNING
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.

displayed.
The current tire temperatures
may change while driving or due
to the external temperature.
Tire and system status are indi-

and a SMS text message on the
Control Display.
Any existing messages are not
deleted if the displayed target
pressure is not reached after the
tire inflation pressure is cor-
rected.
• The system is active and
bases warnings on the dis-
played target pressures.
• For tires with special approval: the system is active
and bases warnings on the
tire inflation pressures stored
during the last reset.

Possible causes:
• Malfunction.
• During tire inflation pressure measurement, after confirma-
tion of the tire settings.
• For tires with special approval: the system is being
reset.

driving.
After a successfully completed
reset, the wheels on the Control
Display are shown in green.
You may interrupt this trip at any
time. When you continue the
reset resumes automatically.
