Toyota Yaris: Fuel Main Valve / Removal

CAUTION:

• Never perform work on fuel system components near any possible ignition sources.
• Vaporized fuel could ignite, resulting in a serious accident.

• Do not perform work on fuel system components without first disconnecting the cable from the negative (-) auxiliary battery terminal.
• Sparks could cause vaporized fuel to ignite, resulting in a serious accident.

NOTICE:

• After the ignition switch is turned off, the radio and display receiver assembly records various types of memory and settings. As a result, after turning the ignition switch off, make sure to wait at least 120 seconds before disconnecting the cable from the negative (-) auxiliary battery terminal.
• This procedure includes the removal of small-head bolts. Refer to Small-Head Bolts of Basic Repair Hint to identify the small-head bolts.
