Happened to me....tooo
 

It was my Memo.....I had my memo set to ON and that was it...it beeped every hour....

There are several options:

1. It's the reminder signal. It goes off 15 seconds before the hour...so it depends what time you are in the car as to whether you hear it or not. Nothing displays on the dash/screen or instrument cluster.

To switch this off press the button with the picture of the clock on it, you will then see your display give you an option for MEMO On/OFF, press underneath the word OFF and you're done.

2. Seat belt reminder....but this keeps going and is more than three beeps!

3. Temperature cold/freezing (ice warning) but this displays the 'Below Temp.; warning...

I guess you've got option 1.

OK...you sorted it anyway! Great..I only know cause it's been drivng me nuts for a week and I got the manual out tonight. All sorted here too!
