CAUTION ● Do not ground electrical accessories directly to the battery terminal. Doing so will bypass the variable control system and the vehicle battery may not charge completely. Refer to "Variable voltage control system (if so equipped) " in the "Maintenance and do-it-yourself" section later in this manual. ● Do not continue driving if the generator belt is loose, broken or missing.
