STARTING AND DRIVING "ACC" mode "IG−ON" mode G31033 G31034 This mode allows some accessories to be operable such as the radio, even if the engine is not running. An amber indicator light turns on at the engine switch. To select the "ACC" mode from "OFF" mode, push the engine switch once without depressing the brake pedal. The engine immobilizer is disabled and the security indicator light goes out. (For details, see "Engine immobilizer" on page 12.) If you cycle once through all the modes ("OFF", "ACC", "IG−ON") with the driver's door closed, the second time you select the "ACC" mode, the above message will appear for a few seconds.
