Indicators & Displays
Display Check
When the ignition switch is turned ON (q), the multi-function display
will temporarily show all the modes and digital segments and initial
message. So, you can make sure the liquid crystal display is
functioning properly.
If any part of this display does not come on during the key on check,
have your dealer check for problems.
