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.
