2008 DODGE RAM 2500 GAS ignition

²Any time you store your vehicle, or keep it out of
service (i.e., vacation) for two weeks or more, run the
air conditioning system at idle for about five minutes
in the fresh air and high blower setting. This will
ensure adequate system lubrication to minimize the
possibility of compressor damage when the system is
started again.
NOTE:When reinstalling the IOD fuse push firmly until
fully seated; the gauges in the instrument cluster will do
a full sweep when the ignition key is cycled to RUN. This
is a normal condition.
NOTE:
When the vehicle is shipped from the factory, the
IOD fuse is in the up, or extracted position. If the radio,
interior lamps, keyless entry, or other features do not work
with the key OFF, check the position of the fuse (or check
to see if the fuse is blown) to ensure that it is fully seated.
When the IOD fuse is extracted, the instrument cluster in
the odometer window will display9NO FUSE.º
