How do I change the time(clock) on my 2001 Honda Civic LX ?

Answer 1

here's the instructions from the owner's manual for that car

Digital Clock

The audio system also displays the
time. To set the time, the ignition
switch must be in ACCESSORY (I)
or ON (II), and you must wait about
five seconds after performing any
other operations with the system.

Adjust the hours by pressing and
holding the CLOCK button, then
pressing the H (Preset 4) button.
Adjust the minutes by pressing and
holding the CLOCK button, then
pressing the M (Preset 5) button.

make sure that you continue to hold the clock button in when you use the radio station buttons to change the hours or minutes. if you just press and release the clock button then try to change the hours or minutes it won't work.

hope that helps
