If you have a sedan there is a digital clock located in 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 three 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.

S (Set): To reset the time to the nearest hour, press the S button.

For example, if the set button is pressed while the time is between 8:00 and 8:29, the display is set to 8:00. If this button is pressed while the time is between 8:30 and 8:59, the display is set to 9:00.

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

If you have a hatchback there is a clock located in the Secondary Information Center (SIC), see Secondary Information Center (SIC) .
