The analog clock is located on the instrument panel above the radio. The clock is not connected with any other vehicle system and runs by itself. To adjust the clock:

  1. Locate the adjustment buttons directly below the clock face.
  2. Push and hold the right adjustment button to move the clock hands forward or the left adjustment button to make the clock hands go backward. Holding either button down will cause the clock to advance faster. Release the button before the desired time is reached.
  3. Push and release either button to adjust the time by one minute increments until the desired time is reached.
