    This is an odd one... Happened today, but has happened on a couple of previous occasions. What am I doing wrong?

    1. Feckwit pulls out right in front of me;
    2. I go for the brakes, and also the horn push in mad panic, i.e. mash steering wheel centre with palm of hand;
    3. I think the horn sounds;
    4. I can't hear the horn itself because of the cacophony coming from the dash/cluster - sounds like the warning bleep when you first switch on, but continuous. No warning lights/messages;
    5. Panic averted, release horn push and the horn stops, but cacophony continues for several seconds;
    6. Eventually noise stops, and several seconds later still, the single "everything OK" beep sounds;
    7. Calm is restored.

    What is going on? Does anyone else have this? I'm baffled as to what the car thinks is wrong, and it certainly is not telling me. :dk:

    Frightened the ***p out of me when it first happened - not expecting it and all that. Come to think of it, it came as a nasty shock on each occasion. Am I going to scare the airbag into deploying itself?

    It doesn't seem to happen if I carefully press the star until the horn sounds - only when in blind panic mode when I'm pressing everything in sight in a bloody hurry!

    I wondered if it is because I am inadvertently catching one of the steering wheel control button pads and it doesn't like it? Do I need to make sure I press the wheel centre? I note the horn symbols are embossed on the edges of the central airbag pad just above the control button pads on both sides. Should I be more specific in precisely where I am pressing it?

    You can press the airbag pad anywhere really. Pushing at the corners is best as this requires the least amount of pressure to be applied.

    very weird though...
