There is a reason that it came on. Something has malfunctioned (usually an emission control device) to casue the light to stay on. A trip to a place like Auto-Zone or O'Reilly's can get you the FREE use of a diagnostic tool to reset the light. It also downloads the codes to tell why it was set in the first place.
Good Luck

How do i reset the service engine light soon? It stays on after i have changed the oil and filter and reset the oil life sensor to 100%.

The service engine soon light indicates a problem.
Take the vehicle to AutoZone and have them read the computer code.
They can give you an idea of what the problem is and reset the light for you.
BTW the service is free

I disconnected and re-connected Battery on 1997 Deville northstar. Service engine soon light came on, will it go off in the 60 miles when computer resets?

If the check engine light comes on, then the coputer has detected a problem. Disconnecting the battery for about 15 minutes will "reset' the computer. Howwever if the problem still exsists, the light will come back on. It could be a simple as a loose gas cap or something more complex. The only way to determine what the problem is, is to retrieve the code(s). You will need an OBD II code reader. In some states your local auto parts store will do this for you.

What does it mean when the dashboard reads gear indicator fault, service ride control and change oil soon even after i just got it changed along with service vehicle thats what keeps popping up on my dash...

Off the top of my head the following may be the case for your 1995 Cadillac Deville based on my 1997 Cadillac Deville knowledge:

gear indicator fault- has to do with the shift lever sensor down on the column by the feet,

service ride control- has to do with the air ride shocks in the back or the compressor in the front or the ride control height,

change oil soon- has to do with not resetting the % oil life (just press reset button for a few seconds when the oil % life is displayed)

Hope this helps you out.

My 2003 cadillac deville-the service engine soon light came on and stayed

On a lot of cars the light is reset when you get an oil change, air filter etc. It's overdue for a "look see". You can always go to advance auto and borrow the code reader for free. Plug it in under your dash and will read and reset any codes

Service soon light came on on my 86 cadillac deville so i was wondering is that the same thing as a check engine light or different?

"service soon" is a reminder that it needs regular maintenance, and usually the dealer has a tool to reset that light on the dashboard, which can be expensive to buy.

If you do all the maint yourself, and you know that all the fluids have been replaced or capped off, you could cover the light with a piece of black electrical tape, then go on with your life.

Whath does "service engine soonmeans"

SERVICE ENGINE SOON and SERVICE ENGINE NOW are 2 amber warning lights pertaining to the vehicles computers.SERVICE SOON advises you of a problem, although not an emergency should be attended to promptly. Your technician can trace the problem by accessing fault codes through the climate control panel. SERVICE NOW indicates a more severe problem which will most likely precipitate a failure / breakdown.
