Your vehicle has a digital clock. The clock is located in the secondary instrument cluster on the center of the instrument panel, above the center air outlets. When the ignition is turned to ACC or ON, the time is displayed in the digital clock. There are two adjusting buttons for the digital clock:

H (Hour): To go forward one hour, press the H button once. To go forward more than one hour, press and hold the button until the correct hour is reached.

M (Minute): To go forward one minute, press the M button once. To go forward more than one minute, press and hold the button until the correct minute is reached.

After disconnecting the battery or replacing the fuse, reset the clock.
