2-3. Fuel and Emission
Fuel-Filler Lid and Cap
WARNING
■When removing the fuel-filler cap, l oosen the cap slightly and wait for
any hissing to stop, then remove it
Fuel spray is dangerous. Fuel can burn skin and eyes and cause illness if
ingested. Fuel spray is released when there is pressure in the fuel tank and
the fuel-filler cap is removed too quickly.
■ Before refueling, stop the engi ne, and always keep sparks and flames
away from the filler neck
Fuel vapor is dangerous. It could be ignited by sparks or flames causing
serious burns and injuries.
Additionally, use of the incorrect fuel-fil ler cap or not using a fuel-filler cap
may result in a fuel leak, which could result in serious burns or death in an
accident.
■ Do not continue refueling after the fuel pump nozzle shuts off automat-
ically
Continuing to add fuel after the fuel pump nozzle has shut off automatically
is dangerous because overfilling the fuel tank may cause fuel overflow or
leakage. Fuel overflow and leakage could damage the vehicle and if the fuel
ignites it could cause a fire and explosion resulting in serious injury or
death.
NOTICE
Always use only a genuine Toyota fuel-filler cap or an approved equivalent,
available at your Toyota dealer. The wrong cap can result in a serious mal-
function of the fuel and emission control systems. It may also cause the
check engine light in the combination meter to illuminate.

NOTICE
If the check fuel cap warning light illuminates, the fuel-filler cap may not be
properly installed. If the warning light illuminates, park your vehicle safely off
the right-of-way, remove the fuel-filler cap and reinstall it correctly. After the
cap has been correctly installed, the fuel cap warning light may continue to
illuminate until a number of driving cycles have been completed. A drive
cycle consists of starting the engine (after four or more hours with the
engine off) and driving the vehicle on city and highway roads.
Continuing to drive with the check fuel cap warning light illuminated could
cause the check engine light to illuminate as well.

4405-3. Owner Maintenance
YARIS iA_OM_OM99Q46z_(U)
●Always check tire pressure when tires are cold.
●Warm tires normally exceed recommended pressures. Do not release
air from warm tires to adjust the pressure.
●Underinflation can cause reduced fuel economy, uneven and acceler-
ated tire wear, and poor sealing of the tire bead, which will deform the
wheel and cause separation of tire from rim.
●Overinflation can produce a harsh ride, uneven and accelerated tire
wear, and a greater po ssibility of damage from road hazards.
Keep your tire pressure at the correct levels. If one frequently needs
inflating, have it inspected.
During rotation, inspect them for
correct balance.
WARNING
■Always inflate the tires to the correct pressure
Overinflation or underinflation of tires is dangerous. Adverse handling or
unexpected tire failure could re sult in a serious accident.
Refer to Tires on ( →P. 560).
■Use only a Toyota-genuine tire valve cap
Use of a non-genuine part is danger ous as the correct tire air pressure
cannot be maintained if the tire valv e becomes damaged. If the vehicle
is driven under this c ondition, the tire air pr essure will decrease which
could result in a serious accident. Do not use any part for the tire valve
cap that is not a Toyota-genuine part.

Do not include
(TEMPORARY USE ONLY)
spare tire in rotation.
