I have a 1988 Honda Legend with automatic transmission. Could somebody please tell me what S4 & POLE buttons mean?

I have Honda Legend 1987 I have same question what is S4 and pole Buttons near the Transmission Gear lever.

From what i believe the S4 button is basically like over drive. It allows for more power, however, it provides better fuel economy. Basically an option for highway driving, or perhaps, towing a trailer.

Thanks Marhong! I still have a Question I haven't got answer of it. What about the "Pole" Button It is next to Hand Brake.

I have Honda Legend 1987 Automatic V6 ALB Exclusive. Could anybody tell me how I can reset or deactivate the beep for speed over 100kmh. My car beeps when I drive it over 100kmh.
