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,

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.

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.

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.

Winter tires are recommended
for operating on winter roads.
Winter tires can be identified by
the symbol with mountain and
snowflake, as well as the M+S
marking on the tire sidewall.
So-called all-season tires with
M+S designation, but without
symbol with mountain and
snowflake, have better winter
characteristics than summer
tires but generally do not
achieve the performance of win-
ter 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
ensure that they remain out-
side the immediate area in a
safe place, such as behind a
guardrail.
• If necessary, set up a warning triangle at an appropriate dis-
tance.
With the Mobility System, minor
tire damage can be sealed tem-
porarily to enable continued
travel. To accomplish this, seal-
ant is pumped into the tires,
which seals the damage from
the inside. • Follow the instructions on
using the Mobility System
found on the compressor and
sealant container.
• Use of the Mobility System may be ineffective if the tire
puncture measures approx.
1/8 inches/4 mm or more.
• Contact your Toyota dealer if the tire cannot be made driv-
able.
• Do not remove foreign bodies that have penetrated the tire.
Only remove foreign objects if
they are visibly protruding
from the tire.
• Pull the speed limit sticker off the sealant container and
apply it to the steering wheel.
• The use of a sealant can
damage the TPM wheel elec-
tronics. In this case, have the
electronics checked and
replaced at the next opportu-
nity.
• The compressor can be used to check the tire inflation pres-
sure.
