Sparks could cause vaporized fuel to ignite, resulting in a serious accident.

To prevent serious injury due to fuel spray from the high-pressure fuel lines, always discharge fuel system pressure before removing any fuel system components.

NOTE:

After the ignition switch is turned off, the radio and display receiver assembly or the radio 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.
