for Nickel Metal Hydride Battery: Refer to PRECAUTION [01/2019 - 09/2022]

for Lithium-ion Battery: Refer to PRECAUTION [04/2020 - 09/2022]

To prevent electric shock, wear insulated gloves when working on wire harnesses and components of the high voltage system.

Be sure to wear insulating gloves when working on high voltage wiring or components.

If work is performed without wearing insulating gloves, there is a danger of electric shock.

NOTE:

After the power switch is turned off, the radio and display receiver assembly records various types of memory and settings. As a result, after turning the power switch off, make sure to wait at least 85 seconds before disconnecting the cable from the negative (-) auxiliary battery terminal.
