I can't change the clock in my Peugeot 306 any ideas

No but just think in 6 months the time will be correct!

wear a watch

ok if its a digital clock in the centre console it will have 1 or 2 buttons on the right press them. if its an analogue clock next to your speedo just turn the knob at the bottom. if it is a modorn car with a computer press your function button til the clock flashes and then press the other button to change the time

its a frog car, what did you expect. simplicity and reliability.

flog it, quickly. you could disconnect the battery for 12 hours..but the car may never start again.

bah! there are some retarded arnt there,here is mine .. press both buttons at the same time, then press the left one untill the time bit is highlighted, the the right one to change it, then after you have done it, leave it and dont press it, it will stop flashing after about 5 seconds

Do you want that changed to socialist time or drunken French autoworker time?

If its the same as my 306 (2001 model). You change the clock with a sharp pencil or pin by sticking it in the holes next to the clock.

2 days have passed & u have not chosen a best answer. Maybe this will help? l am not sure.

The answer to the question could be the same as written in Dutch in my 406 owners manual. Please allow me to translate it to English for you.

DISPLAY B:
a photo is shown of the “multifunctional display screen”. Button 3 is on the left side & button 4 is on the right.

This can show the following information:
* The time, the date, the outside temp, (the Centigrade symbol blinks by chance of slippery roads), info on the radio, check open doors, fuel cap / bonnet is open…
* Warnings that r constantly displayed (i.e. battery not good) or news that is shown for 10 seconds (i.e. fill fuel tank) can be erased by pressing button 3 or 4.
* the onboard computer.

Setting the parameters:
Press button 3 in, & hold this pressed in for 2 seconds.
Afterwards by pressing button 3, various parameters can be selected:
* The language, the hour, minutes, year,month,day, 12/24 hour, temperature in F or C, miles or km.
By pressing button 4 u can change the parameters. Hold the button pressed in to change them at a faster tempo.
If for 10 seconds the button is NOT pressed in, the display gives its basic screen again.

If its in the centre console then there are two buttons (one above the other) to the right of the display. The top button, when pressed adjusts the hours and the bottom button, when pressed adjusts the minutes. That is how it works in mine anyway.
