Sorry, there is no way after 1998 that you can access the obd2 system from the dash buttons, only
with the use of the appropriate scan tool.

Coolant low, steam out of exhaust, and rough idle at start,

Hate to tell you this bud but you have a head problem most definitely
Head gasket is blown or maybe even a cracked head
Bad news is most caddy engines have problems with head bolts upon removal
I would be looking for a used engine

How do I clear the message service

I'm guessing that you're talking about the check engine light (CEL). besides fixing the problem you can take it to the dealer or someone with a VAG-COM to clear the message.

Good price-
Pay $20 and have a mechanic go take a look at the car- if you have a good mechanic, they will gladly go (for compensation of course) and give you an estimate based on a looksee and the comments of the dealer.

Than you can access the total price and value to determine if it suits you.

Besides cash, you can also tell the mechanic that you'll use him exclusively for service in the future.

Engine service soon light

The service engine soon light, or malfunction indicator lamp, indicates that the car's engine management systems are finding a fault somewhere. The vehicle may be running "fine" but when a MIL indicator is on it tells your car's computer to run on a "drive in default". In other words, it senses something wrong and cannot calculate the correct setings to make the engine run as it should so it sets the fuel to air ratio and many other things to values that it knows will make it run so you can have it serviced.

You fuel economy is likely suffering and running and engine on default settings may cause engine deposits and further damage.

You could take your car to autozone and they will pull the codes for free but they may not clear it for you. There is a procedure on many Caddis that allow you to look athe the fault codes throught the welcome or convience center or through the auto climate controls display. I will research the procedure for this vehicle and post it as info becomes available.

You could also disconnect the battery for a few minutes to clear the codes BUT YOUR SECURITY SYSTEM AND OR STEREO LOCKOUT CODE MAY RENDER SOME SYSTEMS USELESS IF YOU DONOT HAVE THE CORRECT CODE TO REACTIVATE THEM. I do not recommend doing it that way.
