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 282, 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 266,
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.

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
WARNING
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.
WARNING
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.
WARNING
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.

Retreaded tires
WARNING
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.

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

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.

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

pressure recommended by
the vehicle manufacturer on
the vehicle placard or tire
inflation pressure label. (If
your vehicle has tires of a dif-
ferent size than the size indi-
cated on the vehicle placard
or tire inflation pressure label,
you should determine the
proper tire inflation pressure
for those tires.) As an added
safety feature, your vehicle
has been equipped with a tire
pressure monitoring system
(TPMS) that illuminates a low
tire pressure telltale when one
or more of your tires is signifi-
cantly under-inflated. Accord-
ingly, when the low tire
pressure telltale illuminates,
you should stop and check
your tires as soon as possi-
ble, and inflate them to the
proper pressure. Driving on a
significantly under-inflated tire
causes the tire to overheat
and can lead to tire failure.
Under-inflation also reduces
fuel efficiency and tire tread
life, and may affect the vehi-
cle's handling and stopping
ability. Please note that the
TPMS is not a substitute for
proper tire maintenance, and
it is the driver's responsibility
to maintain correct tire pres-
sure, even if under-inflation
has not reached the level to
trigger illumination of the
TPMS low tire pressure tell-tale. Your vehicle has also
been equipped with a TPMS
malfunction indicator to indi-
cate when the system is not
operating properly. The TPMS
malfunction indicator is com-
bined with the low tire pres-
sure telltale. When the system
detects a malfunction, the tell-
tale will flash for approxi-
mately one minute and then
remain continuously illumi-
nated. This sequence will
continue upon subsequent
vehicle start-ups as long as
the malfunction exists. When
the malfunction indicator is
illuminated, the system may
not be able to detect or signal
low tire pressure as intended.
TPMS malfunctions may
occur for a variety of reasons,
including the installation of
replacement or alternate tires
or wheels on the vehicle that
prevent the TPMS from func-
tioning properly. Always
check the TPMS malfunction
telltale after replacing one or
more tires or wheels on your
vehicle to ensure that the
replacement or alternate tires
and wheels allow the TPMS
to continue to function prop-
erly.
