Rear luggage storage box—
To keep the lid open, attach the hook as
shown above.
NOTICE
Do not close the back door with the
hook attached, or the hook may be
damaged.
Keep the hook stored in its original posi-
tion as shown when it is not in use.To secure your luggage, use the tie
down hooks as shown above.
The tire tie−down belts are designed to
secure the flat tire. You can also use the
belts to secure your luggage. (To secure
the flat tire, see “—Stowing flat tire” on
page 235 in Section 4.)
See “—Stowage precautions” on page 203
in Section 2 for precautions when loading
luggage.

7. Radial tire or biasply tires—
A
radial tire has “RADIAL” on the
sidewall. A tire not marked with
“RADIAL” is a bias −ply tir e.
8. “TUBELESS” or “TUBE TYPE”— A tubeless tire does not
have a tube inside the tire and air
is directly filled in the tire. A tube
type tire has a tube inside the tire
and the tube maintains the air
pressure.
9. Load limit at maximum cold tire inflation pressure— For details,
see “Vehicle load limits” on page
202 and “Checking and replacing
tires” on page 275.
10.Maximum cold tire inflation pressure— This means the pres-
sure to which a tire may be in-
flated. For details about recom-
mended cold tire inflation
pressure, see “Tires” on page 300. 11. Summer tire or all season
tire— An all season tire has “M+S”
on the sidewall. The tire not
marked with “M+S” is a summer
tire. For details, see “Types of
tires” on page 205.

symbols.
1. “TEMPORARY USE ONLY”— A
compact spare tire is identified by
the phrase “TEMPORARY USE
ONLY” molded into its sidewall.
This tire is designed for temporary
emergency use only. For details,
see “Compact spare tire” on page
228.
2. Tire size— F or det ails, see “— Ti re
size” on page 196.
3. DOT and Tire Identification Number (TIN)— For details, see
“—DOT and Tire Identification
Number (TIN)” on page 195.
4. The location of the tread wear indicators— For details, see
“Checking and replacing tires” on
page 275.
5. Load limit at maximum cold tire inflation pressure— For details,
see “Vehicle load limits” on page
202 and “Checking and replacing
tires” on page 275.

6. Maximum cold tire inflation
pressure— This means the pres-
sure to which a tire may be in-
flated. For details about recom-
mended cold tire inflation
pressure, see “Tires” on page 300.
7. Tire ply composition and mate- rials— Plies mean a layer of rub-
ber −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 directly 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. A tire not marked with
“RADIAL” is a bias −ply tir e.
This illustration indicates typical DOT
and Tire Identification Number (TIN).
1. “DOT” symbol
2. Tire Identification Number (TIN)
3. Tire manufacturer ’s identification mark
4. Tire size code
5. Manufacturer ’s optional tire type code (3 or 4 letters)
6. Manufacturing week
7. Manufacturing year The “DOT” symbol certifies that the
tire conforms to applicable Federal
Motor Vehicle Safety Standards.

198 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. 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.
