To prevent burns, do not touch the engine, exhaust manifold or other high temperature components while the engine is hot.

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.
