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.

The display of the current tire
pressure may be limited when
the vehicle is stationary. After a
short drive, the tire pressure is
updated.
With tires that cannot be found
in the tire pressure values on
the Control Display, reset the
Tire Pressure Monitor TPM.
For speeds of up to 100
mph/160 km/h and for optimum
driving comfort, note the pres-
sure values in the tire inflation
pressure table, refer to page
273, and adjust as necessary. These pressure values can also
be found on the tire inflation
pressure label on the driver's
door pillar.
Do not exceed a speed of 100
mph/160 km/h.

Temperature A B C
All passenger vehicle tires must
conform to Federal Safety
Requirements in addition to
these grades
The treadwear grade is a com-
parative rating based on the
wear rate of the tire when tested
under controlled conditions on a
specified government test
course. E.g., a tire graded 150
would wear one and one-half, 1
g, times as well on the govern-
ment course as a tire graded
100. The relative performance
of tires depends upon the actual
conditions of their use, however,
and may depart significantly
from the norm due to variations
in driving habits, service prac-
tices and differences in road
characteristics and climate.
The traction grades, from high-
est to lowest, are AA, A, B, and
C.Those grades represent the
tire's ability to stop on wet pave-
ment as measured under con-
trolled conditions on specified
government test surfaces of
asphalt and concrete. A tire
marked C may have poor trac-
tion performance.
The traction grade assigned to
this tire is based on
straight-ahead braking traction
tests, and does not include
acceleration, cornering, hydro-
planing, or peak traction charac-
teristics.
The temperature grades are A,
the highest, B, and C, represent-
ing the tire's resistance to the
generation of heat and its ability
to dissipate heat when tested
under controlled conditions on a
specified indoor laboratory test
wheel. Sustained high tempera-
ture can cause the material of
the tire to degenerate and
reduce tire life, and excessive
temperature can lead to sudden
tire failure.
The grade C corresponds to a
level of performance which all
passenger vehicle tires must
meet under the Federal Motor
Vehicle Safety Standard No.
109. Grades Band A represent
higher levels of performance on
the laboratory test wheel than
the minimum required by law.

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.Distributed over the tire circum-
ference are the tire manufac-
turer's wear indicators with a
height of at least 0.06 in/1.6
mm, which serve as an indicator
of tire tread wear.
The positions of the wear indica-
tors are marked on the tire side-
wall with TWI, Tread Wear
Indicator.
Irrespective of the wear indica-
tors, observe the statutory regu-
lations on the minimum tread
depth.
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

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-

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
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.
• Uneven wear pattern, e.g., increased wear in the area of
the tire shoulder.
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.
The following properties are rec-
ommended and approved by the
manufacturer of the vehicle for
the approved wheels and tires
per vehicle type and special
equipment:
• Wheel and tire combinations.
• Rim designs.
• Tire sizes.
• Tire brands.
You can ask your Toyota dealer
about the approved wheels and
tires for the vehicle and the spe-
cial equipment.
Safety information
WARNING
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.
WARNING
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.

General information

2805-1. MOBILITY
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.
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
unexpected loosening of the lug
bolts and damage to the brake
discs. There is a risk of 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.
Recommended tire brands
New tires
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 acci-
dent. The manufacturer of the
vehicle does not recommend the
use of retreaded tires.
