If the tire pressure warning light does not
blink slowly three times when you push
and hold the reset switch, initialization has
failed and the tire pressure warning sys-
tem may not work properly. In this case,
initialize the system again. If initialization
cannot be performed, have the system
checked at your Scion dealer.
CAUTION
Do not push the reset switch without
first adjusting the tire inflation pres-
sure to the specified level. Other-
wise, the tire pressure warning light
may not come on even if the tire
inflation pressure is low, or it may
come on when the tire inflation pres-
sure is actually normal.
Parking brake
When parking, firmly apply the parking
brake to avoid inadvertent creeping.
To set: Pull up the lever. For better hold-
ing power, first depress the brake pedal
and hold it while setting the parking
brake.
To release: Pull up the lever slightly (1),
press the lock release button (2), and low-
er (3).
To remind you that the parking brake is
set, the parking brake reminder light in
the instrument panel remains on until you
release the parking brake.

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 239.
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 261.
10. Uniform tire quality grading— For details, see “Uniform tire quali-
ty grading” that follows.

162This illustration indicates typical tire
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
196.
2. Tire size— For details, see “Tire
size” on page 164.
3. DOT and Tire Identification Number (TIN)— For details, see
“DOT and Tire Identification Num-
ber (TIN)” on page 163.
4. Location of treadwear indica- tors— For details, see “Checking
and replacing tires” on page 239.
5. Load limit at maximum cold tire inflation pressure— For details,
see “Checking and replacing tires”
on page 239.

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 261.
7. 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.
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.

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.
