My 85 300sd came with an alarm but no instructions. there is a small black button near my right knee and today I pushed it. Now the alarm is not working! I tried to push it again, both with the car on and off and it wont go back on. Any suggestions or where I can look for a mfg info on it? Thanks!

Your best bet is to find the alarm "brain" and try an internet search for the manual of the alarm brand. I may be under your dash or in the engine compartment (a bad place for it) or under the passenger foot rest area, where the factory alarm should be.

The switch sounds like the "valet" button.

thanks alot! I brought my car in for a realignment cause they didnt do a good job the 1st time and i got a mysterious coolant leak from the hose that goes behind the firewall (it has a "Y" in it" so it is stuck there now. I am wondering if this guy is taking me for a ride. have to find a better mechanic that I can trust. Anyway will check it out then - thanks for the heads up~!
