- Sparks could cause vaporized fuel to ignite, resulting in a serious accident.
NOTICE:
- After the engine switch is turned off, the radio receiver assembly records various types of memory and settings. As a result, after turning the engine switch off, make sure to wait at least 85 seconds before disconnecting the cable from the negative (-) battery terminal. (for Audio and Visual System)
- After the engine switch is turned off, the radio receiver assembly records various types of memory and settings. As a result, after turning the engine switch off, make sure to wait at least 85 seconds before disconnecting the cable from the negative (-) battery terminal. (for Navigation System)
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.
