RE: How do I set the clock in my CITROEN BERLINGO?
This is quite a tedious job, and quite why Citroen made like this is beyond me. Anyway....
Turn key in the ignition to the set position before firing her up - so all the dash lights are on.
Wait for the lcd screen to clear to 'normal' (if yours does what ours does and cycles through some basic diagnostic type checks before displaying the mileage, etc).
There are two black knobs sticking out of the speedo 'screen in front of you
Press and hold one of them* and after a few seconds the time (hours) on the display will start to flash.
You can then press the other one to alter the flashing digit.
Once that one is set, press the first knob again and the second pair of digits (minutes) will flash. Again, press the other knob and these will change.
Once at what it should be, you need to press the first button again to set the time.
You could try starting the car at that point but it doesn't always save the time you've just set up....
* - you'll notice I am not saying which one, this is because I cannot remember and I'm at work and the car is 100 miles away!
Trial and error is needed, but the above are the basic principles to use.
Ignition on, let the display settle down if it needs to, press your knobs in an organised way and you should end up working out how to get the result you're after!
Good luck, and don't thank me until it works!!!
