I sometimes get a warning chime while driving but no warning lights ANY HELP PLEASE

[color=#0000ff][size=5][font=comic sans ms,cursive]It could be the low outside temperature warning hovering around the 4 degree C mark, the light will only come on when the sensor gets a positive [i]below 4 degree C[/i] signal.[/font][/size][/color]

and depending how its set up may beep again when under 0 degrees is hit...

I however, dont get a beep at all on the low temp

the beeps can be switched off via the onboard computer. Whilst stationary, scroll down to setup, and then press the reset button, then scroll down to chimes, press the reset button, then scroll down to exit. You will probably be prompted to save the settings to the key, choose yes.

That should stop the beeps
