Had mine 4 weeks, 800 miles. Love the car. A few little things - I agree with the post about the brakes feeling weird and having no a mind of their own, but that doesn't particularly bother me.
3 things I've questions on. One is a symbol on the console - just want to check that it means that the passenger airbag is disabled. Not sure why there is a 2 number next to the symbol - 2nd person? Just seems odd, and can't get 100% confirmed from manual
Second is sat Nav audio - can you turn off the voice and just receive the onscreen directions? I use sat Nav in the drive to work so it can make the best use of the batteries and to check for traffic. But I've driven the route for 5 years so I know the way!!!
And 3rd ... I can heard a constant very high pitch noise. Most noticeable when the stereo is off. My dad used to have an animal/pest scarer and the range of noise is like that (he couldn't hear it). Anyone rlse? Would rather not both with taking it in, as I bet they will say they can't hear it. Anyway - any comments appreciated.
Airbag - the light only goes out if the car detects someone suitable is in the seat, if say a small child sits in the chair and the light doesnt go out thats means the airbag is NOT active - i dont believe you can disable this, its all automatic to be as safe as possible - Volvo used to prevent you from disabling the front airbag and therefore you couldn't put a baby car seat in the front - reason being the safest place for a baby is in a rear ward facing seat in the rear.
Sat Nav - took me a few days until i found you can mute it just like the radio (same button on the steering wheel ) you have to do it when the directions are being announced or else it just mutes the radio/media
High pitch noise ? - sorry no idea
