Button on Steering Column? 306 Cabrio

I've looked through the handbook several times, but can see no sign of
what this button does. From the graphic, I assume it has something to
do with the alarm/immob. Can anyone tell me about it ?

TIA

David

 

For disabling the ultrasound sensors for the alarm - allowing you to
`alarm` the car whilst the roof is down or when the windows are open.

open.

Thanks for that Jim. At the risk of seeming to be completely stupid -
how exactly do I use it
and how do I re-engage the sensors?
I can't imagine why such an important feature isn't in the handbook.

Thanks again

1) Ignition off - press and hold down the button until the alarm dash light
is on continously
2) out of car car close door/s and use fob to engage the alarm system
3) the alarm dash light will blink as normal

The alarm defaults to full system when it is unarmed and then reset without
the above procedure

Thanks for getting back to me. That's just what I needed to know.

Best regards

Steve

 

Apologies for not supplying the info myself - I missed your follow up. Glad
you are sorted!

Thanks Jim. I think I'm as sorted as I'll ever be !
