6. Maximum cold tire inflation
pressure— This means the pres-
sure to which a tire may be in-
flated. For recommended cold tire
inflation pressure, see “Tires” on
page 315.
7. Tire ply composition and materi- als— Plies mean a layer of rubber −
coated parallel cords. Cords mean
the strands forming the plies in the
tire.
8. “TUBELESS” or “TUBE TYPE” —A tubeless tire does not have a
tube inside the tire and air is direct-
ly filled in the tire. A tube type tire
has a tube inside the tire and the
tube maintains the air pressure.
9. Radial tires or biasply tires— A
radial tire has “RADIAL” on the
sidewall. The tire not marked with
“RADIAL” is a bias −ply tir e.

—Uniform tire quality grading
This information has been prepared
in accordance with regulations issued
by the National Highway Traffic Safe-
ty Administration of the U.S. Depart-
ment of Transportation. It provides
the purchasers and/or prospective
purchasers of Toyota vehicles with in-
formation on uniform tire quality grad-
ing.
Your Toyota dealer will help answer
any questions you may have as you
read this information.
DOT quality grades—All passenger
car tires must conform to Federal
Safety Requirements in addition to
these grades. Quality grades can
be found where applicable on the
tire sidewall between tread shoul-
der and maximum section width.
For example: Treadwear 200 Trac-
tion AA Temperature A.Tread wear—
The tread wear grade
is a comparative rating based on the
wear rate of the tire when tested un-
der controlled conditions on a speci-
fied government test course. For ex-
ample, a tire graded 150 would wear
one and a half (1 −1/2) times as well
on the government 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 hab-
its, service practices and differences
in road characteristics and climate. Traction AA, A, B, C—
The traction
grades, from highest to lowest, are
AA, A, B, and C, and they represent
the tire’s ability to stop on wet pave-
ment as measured under controlled
conditions on specified government
test surfaces of asphalt and concrete.
A tire marked C may have poor trac-
tion performance.
Warning: The traction grade assigned
to this tire is based on braking
(straight ahead) traction tests and
does not include cornering (turning)
traction.

224 Temperature A, B, C—T he tem per a-
ture grades are A (the highest), B,
and C, representing the tire’s resis-
tance 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 temperature
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 cor-
responds to a level of performance
which all passenger car tires must
meet under the Federal Motor Vehicle
Safety Standard No. 109. Grades B
and A represent higher levels of per-
formance on the laboratory test wheel
than the minimum required by law.
Warning: The temperature grades for
this tire are established for a tire that
is properly inflated and not over-
loaded. Excessive speed, underinfla-
tion, or excessive loading, either sep-
arately or in combination, can cause
heat buildup and possible tire failure.

228 Vehicle load limits include total load
capacity, seating capacity, towing ca-
pacity and cargo capacity. Follow the
load limits shown below.
Total load capacity:
379 kg (835 lb.)
Total load capacity means combined
weight of occupants, cargo and lug-
gage.
Seating capacity: Total 5 (Front 2, Rear 3)
Seating capacity means the maximum
number of occupants whose esti-
mated average weight is 68 kg (150
lb.) per person. Depending on the
weight of each person, the seating ca-
pacity given may exceed the total
load capacity.
NOTICE
Even if the number of occupants
are within the seating capacity,
do not exceed the total load ca-
pacity.
Towing capacity
Toyota does not recommend towing
a trailer with your vehicle. Your ve-
hicle is not designed for trailer towing.
Cargo capacity
Cargo capacity may increase or de-
crease depending on the size (weight)
and the number of occupants. For de-
tails, see “Capacity and distribution”
that follows.
CAUTION
Do not apply the load more than
each load limit. That may cause
not only damage to the tires, but
also deterioration to the steering
ability and braking ability, which
may cause an accident.
When stowing cargo and luggage in
the vehicle, observe the following: Put cargo and luggage in the lug-
gage compartment when at all
possible. Be sure all items are se-
cured in place.
 Be careful to keep the vehicle bal-
anced. Locating the weight as far
forward as possible helps maintain
balance.
 For better fuel economy, do not
carry unneeded weight.
CAUTION
To prevent cargo and l uggage
from sliding forward during
braking, do not stack anything
in the luggage compartment.
Keep cargo and luggage low,
as close to the floor as pos-
sible.
Vehicle load limits Cargo and luggage—
—Stowage precautions

229
Never allow anyone to ride in
the luggage compartment. It is
not designed for passengers.
They should ride in their seats
with their seat belts properly
fastened. Otherwise, they are
much more likely to suffer seri-
ous bodily injury, in the event
of sudden braking or a colli-
sion.
 Do not place anything on the
luggage cover. Such items may
be thrown about and possibly
injure people in the vehicle
during sudden braking or an
accident. Secure all items in a
safe place.
 Do not drive with objects left
on top of the instrument panel.
They may interfere with the
driver’s field of view. Or they
may move during sharp vehicle
acceleration or turning, and im-
pair the driver’s control of the
vehicle. In an accident they
may injure the vehicle occu-
pants.NOTICE
Do not load the vehicle beyond
the vehicle capacity weight giv-
en in Section 9.
Cargo capacity depends on the to-
tal weight of the occupants.
(Cargo capacity) = (Total load capac-
ity) – (Total weight of occupants)
STEPS FOR DETERMINING COR-
RECT LOAD LIMIT
1. Locate the statement “The com- bined weight of occupants and car-
go should never exceed XXX
pounds” on your vehicle’s placard.
2. Determine the combined weight of the driver and passengers that will
be riding in your vehicle.
3. Subtract the combined weight of the driver and passengers from
XXX kilograms or XXX pounds.
—Capacity and distribution

2304. The resulting figure equals the
available amount of cargo and lug-
gage load capacity. For example,
if the “XXX” am ount equals 1400
lbs. and there will be five 150 lb.
passengers in your vehicle, the
amount of available cargo and lug-
gage load capacity is 650 lbs.
(1400–750 (5x150)=650 lbs).
5. Determine the combined weight of luggage and cargo being loaded on
the vehicle. That weight may not
safely exceed the available cargo
and luggage load capacity calcu-
lated in Step 4.
6. If your vehicle will be towing a trail- er, load from your trailer will be
transferred to your vehicle. Consult
this manual to determine how this
reduces the available cargo and
luggage load capacity of your ve-
hicle. Toyota does not recommend towing
a trailer with your vehicle. Your ve-
hicle is not designed for trailer towing.

EXAMPLE ON YOUR VEHICLE
In case that 2 people with the com-
bined weight of 166 kg (366 lb.) are
riding in your vehicle with the total
load capacity of 379 kg (835 lb.), the
available amount of cargo and lug-
gage load capacity will be as follows:
379 kg – 166 kg = 213 kg.
( 835 lb. – 366 lb. = 469 lb. )
From this condition, if 3 more passen-
gers with the combined weight of 176
kg (388 lb.) get on , the av ailable car-
go and luggage load will be reduced
as follows:
