equipped with low-profile tires.
Indications of tire damage or
other vehicle malfunctions:
• Unusual vibrations.
• Unusual tire or running noises.
• Unusual handling such as a strong tendency to pull to the
left or right.
Damage can be caused by the
following situations, for instance:
• Driving over curbs.
• Road damage.
• Tire inflation pressure too low.
• Vehicle overloading.
• Incorrect tire storage.
Have mounting and wheel bal-
ancing carried out by your Toy-
ota dealer.
You can ask your Toyota dealer
about the correct wheel/tire
combination and wheel rim ver-
sions for the vehicle.
Safety information
WA R N I N G
Damaged tires can lose tire infla-
tion pressure, which can lead to
loss of vehicle control. There is a
risk of an accident. If tire damage
is suspected while driving, imme-
diately reduce speed and stop.
Have wheels and tires checked.
For this purpose, drive carefully to
the nearest your Toyota dealer.
Have vehicle towed or trans-
ported as needed. Do not repair
damaged tires, but have them
replaced.
WA R N I N G
Tires can become damaged by
driving over obstacles, e.g., curbs
or road damage, at high speed.
Larger wheels have
a smaller tire
crosssection. The smaller the tire
cross-section, the higher the risk
of tire damage. There is a danger
of accidents and property dam-
age. If possible, avoid driving over
objects or road conditions that
may damage tires, or drive over
them slowly and carefully.

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

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

Filling the tire with sealant
Safety information
WA R N I N G
If the exhaust pipe is blocked or
ventilation is insu fficient, harmful
exhaust gases can enter into the
vehicle. The exh aust gases con-
tain pollutants which are colorless
and odorless. In enclosed areas,
exhaust gases can also accumu-
late outside of the vehicle. There
is danger to life. Keep the exhaust
pipe free and ensure sufficient
ventilation.
NOTICE
The compressor can overheat
during extended operation. There
is a risk of damage to property. Do
not run the compressor for more
than 10 minutes.

While the tire is being filled with
sealant, the tire inflation pres-
sure may sporadically reach
approx. 5 bar. Do not switch off
the compressor at this point.
1Switch off the compressor.
2 Read the tire inflation pres-
sure on the tire pressure
gauge.
To continue the trip, a tire infla-
tion pressure of at least 2 bar
must be reached.
1 Unscrew the filling hose of
the sealant container from
the tire valve.
2 Press the red unlocking
device.
3 Remove the sealant con-
tainer from the compressor.
4 Wrap and store the sealant
container in suitable material
to avoid dirtying the cargo

Reset the Tire Pressure Monitor
TPM, refer to page 280.
Replace the nonworking tire and
the sealant container of the
Mobility System promptly.
Tire chains cannot be mounted.
Snow tires should be used
instead.
The system monitors tire infla-
tion pressure in the four
mounted tires. The system
warns you if there is a loss of
pressure in one or more tires. Sensors in the tire valves mea-
sure the tire inflation pressure
and tire temperature.
The system detects the
mounted tires automatically. The
system displays the specified
nominal pressure values on the
Control Display and compares
these values to the actual tire
pressure values.
If tires are being used that are
not specified on the tire inflation
pressure details on the vehicle,
refer to page 264, such as tires
with special approval, the sys-
tem needs to be actively reset.
The system will then take over
the actual tire inflation pressures
as the target pressures.
When operating the system,
also note the additional informa-
tion found in the Tire inflation
pressure, refer to page 264.

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.
• TPM does not activate until
after driving for a few minutes:
• After a tire or wheel replacement.
• Reset, for tires without special approval.
• After changing the tire setting.
• For tires with special approval:
• After a tire or wheel replacement,
a reset was perfo rmed with the
correct tire inflation pressure.
• After the tire inf lation pressure
was adjusted to a new value, a
reset was p erformed.
• 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 264, 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
WA R N I N G
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.
