instrument panel when activated and will also
appear on the HUD:

and ICE POSSIBLE when there are messages
on the DIC trip computer.
The HUD will also display the following messages
when these systems are active:

Notice: If you try to use the HUD image as a
parking aid, you may misjudge the distance
and damage your vehicle. Do not use the
HUD image as a parking aid.
When the HUD is on, the speedometer reading
will continually be displayed. The current radio
station or CD track number will display for a short
period of time after the radio or CD track status

warnings, or turn-by-turn navigation information
are displayed on the HUD.
