98 S-600 W140 horn problems

[airdam]

My horn keeps honking when I drive. How do I take off the horn pad on the steering wheel so that I can see what is the problem with my horn button. It is emabarrassing as the horn honks a continuous blare as I drive down the street. the only way to make it stop temporarily is to hit the horn pad on my steering wheel.

Help anyone.

thanks.
