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 (-) battery terminal.
  • Sparks could cause vaporized fuel to ignite, resulting in a serious accident.

PROCEDURE

1. PRECAUTION

NOTICE:

After turning the engine switch off, waiting time may be required before disconnecting the cable from the negative (-) battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) battery terminal notices before proceeding with work.
