symbols.
1. Tire size— For details, see “Tire
size” on page 148.
2. DOT and Tire Identification Number (TIN)— For details, see
“DOT and Tire Identification Num-
ber (TIN)” on page 147.
3. Location of tread wear indica- tors— For details, see “Checking
and replacing tires” on page 217.
4. Tire ply composition and materi- als— Plies mean a layer of rub-
ber–coated parallel cords. Cords
mean the strands forming the plies
in the tire.
5. 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 158.
6. Radial tires or bias–ply tires— A
radial tire has “radial” on the side-
wall. A tire not marked with “radial”
is a bias–ply tire.

7. “TUBELESS” or “TUBE TYPE”
—Tubeless tire does not have a
tube inside the tire and air is direct-
ly filled in the tire, avoiding rapid
air leakage even if the tire is nailed
and preventing the tire from burst-
ing with a shock. Tube type tire has
a tube inside the tire and that tube
maintains the air pressure.
8. Load limit at maximum cold tire inflation pressure— For details,
see “Checking and replacing tires”
on page 217.
9. 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 237.
10. Uniform tire quality grading— For details, see “Uniform tire quali-
ty grading” that follows.

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 237.
7. Tire ply composition and materi- als— Plies mean a layer of rub-
ber–coated parallel cords. Cords
mean the strands forming the plies

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 that
tube maintains the air pressure.
9. Radial tires or bias–ply tires— A
radial tire has “RADIAL” on the
sidewall. The tire not marked with
“RADIAL” is a bias–ply tire.

Types of tires
Determine what kind of tires your
vehicle is originally equipped with.
1. Summer tires
Summer tires are high–speed capabil-
ity tires best suited to highway driving
under dry conditions.
Since summer tires do not have the
same traction performance as snow
tires, summer tires are inadequate for
driving on snow–covered or icy roads.
For driving on snow–covered or icy
roads, we recommend using snow
tires. If installing snow tires, be sure
to replace all four tires.
2. All season tires All season tires are designed to pro-
vide better traction in snow and to be
adequate for driving in most winter
conditions, as well as for use all year
round. All season tires, however, do not have
adequate traction performance
compared with snow tires in heavy or
loose snow. Also, all season tires fall
short in acceleration and handling
performance compared with summer
tires in highway driving.
The details about how to distinguish
summer tires from all season tires are
described on page 144.
CAUTION

Do not mix summer and all sea-
son tires on your vehicle as
this can cause dangerous han-
dling characteristics, resulting
in loss of control.
 Do not use tires other than the
manufacturer’s designated
tires, and do not mix tires or
wheels of the sizes different
from the originally equipped
tires and wheels.

162
Do not drive in excess of the speed
limit. Even if the legal speed limit
permits it, do not drive over 140
km/h (85 mph) unless your vehicle
has high–speed capability tires.
Driving over 140 km/h (85 mph) may
result in tire failure, loss of control
and possible injury. Be sure to con-
sult a tire dealer to determine
whether the tires on your vehicle
are high–speed capability tires or
not before driving at such speeds.
Do not continue normal driving
when the brakes are wet. If they are
wet, your vehicle will require a
longer stopping distance, and it
may pull to one side when the
brakes are applied. Also, the park-
ing brake will not hold the vehicle
securely.
Winter driving tips
Make sure you have a proper freeze
protection for engine coolant.
Only use “Toyota Super Long Life Coolant”
or similar high quality ethylene glycol
based non–silicate, non–amine, non–nitrite,
and non–borate coolant with long–life
hybrid organic acid technology. (Coolant
with long–life hybrid organic acid
technology is a combination of low
phosphates and organic acids.)
See “Checking the engine coolant level”
on page 212 for details of coolant type
selection.
“Toyota Super Long Life Coolant” is a
mixture of 50% coolant and 50% deionized
water. This coolant provides protection
down to about –35C (–31 F).
NOTICE
Do not use plain water alone.
Check the condition of the battery and
cables.
Cold temperatures reduce the capacity of
any battery, so it must be in top shape
to provide enough power for winter start-
ing. Section 7–3 tells you how to visually
inspect the battery. Your Scion dealer and
most service stations will be pleased to
check the level of charge.
Make sure the engine oil viscosity is
suitable for the cold weather.
See page 211 for recommended viscosity.
Leaving a heavy summer oil in your ve-
hicle during winter months may cause
harder starting. If you are not sure about
which oil to use, call your Scion deal-
er—they will be pleased to help.
Keep the door locks from freezing.
Squirt lock de–icer or glycerine into the
locks to keep them from freezing. To open
a frozen lock, try heating the key before
inserting it.

218NOTICE
Low profile tire like 215/45ZR17
may have greater damage than
usual tires to its tire wheel
when receiving impact from the
road surface. Therefore, pay
attention to the followings.

Be sure to use with proper
tire pressure. If the tire pres-
sure is low, the tire may
have a greater damage. For
detailed information about
tire pressure, see page 237.
 Avoid driving onto high,
sharp–edged objects and oth-
er road hazards. Failure to
do so can lead to severe tire
damage.
The effectiveness of snow tires is
lost if the tread wears down below
4 mm (0.16 in.). If you have tire damage such as
cuts, splits, cracks deep e
nough to
expose the fabric, or bulges indi-
cating internal damage, the tire
should be repl aced.
If a tire often goes flat or cannot be
properly repaired due to the size or
location of a cut or other damage, it
should be replaced. If you are not
sure, consult with your Scion dealer.
If air loss occurs while driving, do not
continue driving. Driving even a short
distance can damage a tire beyond
repair.
An y ti res wh i ch are over 6 years
old must be checked by a qualified
technician even if damage is not
obvious.
Tires deteriorate with age even if they
have never or seldom been used.
This applies also to the spare tire and
tires stored for future use. REPLACING YOUR TIRES
When replacing a tire, use a tire of
the same size and construction,
and the same or greater maximum
load as the originally installed
tires.
Using any other size or type of tire
may seriously affect handling, ride,
speedometer/odometer calibration,
ground clearance, and clearance be-
tween the body and tires or snow
chains.
Check that the maximum load of the
replaced tire is greater than 1/2 of the
Gross Axle Weight Ratings (GAWR)
of either the front axle or the rear
axle, whichever is greater. As for the
maximum load of the tire, see the load
limit at maximum cold tire inflation
pressure mentioned on the sidewall
of the tire, and as for the Gross Axle
Weight Ratings (GAWR), see the Cer-
tification Label. For details about the
sidewall of the tire and the Certifica-
tion Label, see pages 144 and 141.
