d Care

Clean the webbing with a mild soap solution recommended for uphol-
stery or carpets. Follow instructions. Do not bleach or dye the web-
bing; this may weaken it.

After cleaning the belts, thoroughly dry the belt webbing and make
sure there is no remaining moisture before retracting them.

If the windows become covered with an oily, greasy, or waxy film,
clean them with glass cleaner. Follow the directions on the container.

Rubber floor mats should be cleaned with mild soap and water only.

After removing the floor mats for cleaning, always reinstall them
securely. (

not provide adequate protection.

Cleaning the Window Interiors

NOTICE

●

Do not scrape or scratch the inside of the window glass. It could damage
the thermal filaments.

●

When washing the inside of the window glass, use a soft cloth dampened

Cleaning the Floor Mats

WARNING

■

Do not use rubber cleaners, such as tire cleaner or tire shine, when
cleaning rubber floor mats

Parking in an Emergency

The hazard warning lights should
always be used when you stop on
or near a roadway in an emer-
gency.

The hazard warning lights warn
other drivers that your vehicle is a
traffic hazard and that they must
take extreme caution when near
it.

Depress the hazard warning flasher and all the turn signals will flash.
The hazard warning indicator lights in the instrument cluster flash
simultaneously.

●

The turn signals do not work when the hazard warning lights are on.

●

Check local regulations about the use of hazard warning lights while the
vehicle is being towed to verify that it is not in violation of the law.

Your Scion has a temporary spare tire. The temporary spare tire is
lighter and smaller than a conventional tire, and is designed only for
emergency use and should be used only for VERY short periods.
Temporary spare tires should NEVER be used for long drives or
extended periods.

■

Lift the Trunk mat.

Turn the spare tire hold-down
bolt counterclockwise.

WARNING

■

Do not install the temporary spare tire on the front wheels (driving
wheels)
Driving with the temporary spare tire on one of the front driving wheels
is dangerous. Handling will be affected. You could lose control of the
vehicle, especially on ice or snow bound roads, and have an accident.
Move a regular tire to the front wheel and install the temporary spare tire
to the rear.

NOTICE

●

When using the temporary spare tire, driving stability may decrease
compared to when using only the conventional tire. Drive carefully.

●

To avoid damage to the temporary spare tire or to the vehicle, observe
the following precautions:

• Do not exceed 50 mph (80 km/h).
• Avoid driving over obstacles. Also, do not drive through an auto-

matic car wash. This tire’s diameter is smaller than a conventional
tire, so the ground clearance is reduced.

• Do not use a tire chain on this tire because it will not fit properly.
• Do not use your temporary spare tire on any other vehicle, it has

been designed only for your Scion.

• Use only one temporary spare tire on your vehicle at the same time.

Changing a Flat Tire

Park on a level surface off the right-of-way and firmly set the park-
ing brake.

Put a vehicle with an automatic transaxle in Park (P), a manual
transaxle in Reverse (R) or 1, and turn off the engine.

Turn on the hazard warning flasher.

Have everyone get out of the vehicle and away from the vehicle
and traffic.

Remove the jack, tool, and spare tire (

P. 483).

Block the wheel diagonally
opposite the flat tire. When
blocking a wheel, place a tire
block both in front and behind
the tire.

●

If the following occurs while driving, it could indicate a flat tire.

• Steering becomes difficult.
• The vehicle begins to vibrate excessively.
• The vehicle pulls in one direction.

●

Make sure the jack is well lubricated before using it.

●

When blocking a tire, use rocks or wood blocks of sufficient size if possi-
ble to hold the tire in place.

If you have a flat tire, drive slowly to a level spot that is well off
the road and out of the way of traffic to change the tire.

Stopping in traffic or on the shoulder of a busy road is danger-
ous.

portion of their body under a vehicle that is supported by a jack.

■

Never allow anyone inside a vehicle supported by a jack
Allowing someone to remain in a vehicle supported by a jack is danger-
ous. The occupant could cause the vehicle to fall resulting in serious
injury.

ous as it could cause the vehicle to fall off the jack resulting in an acci-
dent.

If your vehicle has Scion optional antitheft wheel lug nuts, one on
each wheel will lock the tires and you must use a special key to unlock
them. This key will attach to the lug wrench. Register them with the
lock manufacturer by filling out the card provided in the glove com-
partment and mailing it in the accompanying envelope. If you lose this
key, consult your Scion dealer or use the lock manufacturer’s order
form, which is with the registration card.

Accessory wheel locks cannot be used on steel wheels. This includes
situations when the spare tire is installed. If the spare tire is installed,
one of the original lug nuts (which should still be in the vehicle) must
be installed in place of the wheel lock.
