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.

HINT:

When the cable is disconnected / reconnected to the auxiliary battery terminal, systems temporarily stop operating. However, each system has a function that completes learning the first time the system is used.

Learning completes when vehicle is driven
