Toyota Yaris: Fuel and Emission / Fuel-Filler Lid and Cap
WARNING
When removing the fuel-filler cap, loosen 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 engine, 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-filler 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
automatically
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
malfunction of the fuel and emission control systems.
It may also cause the check engine light in the combination meter to
illuminate.
WARNING
Do not drive your vehicle if you smell exhaust gas inside the
vehicle
Engine exhaust gas is dangerous. This gas contains carbon monoxide
(CO), which is colorless, odorless, and poisonous...
Before refueling, close all the doors, windows, and the liftgate/trunk
lid, and switch the ignition OFF.
To open the fuel-filler lid, pull
the remote fuel-filler lid release...
