YellowIOD – SpareCAUTION!
•When installing the totally integrated power mod-
ule cover, it is important to ensure the cover is
properly positioned and fully latched. Failure to
do so may allow water to get into the totally
integrated power module and possibly result in a
electrical system failure.
•When replacing a blown fuse, it is important to
use only a fuse having the correct amperage rating.
The use of a fuse with a rating other than indicated
may result in a dangerous electrical system over-
load. If a properly rated fuse continues to blow, it
indicates a problem in the circuit that must be
corrected.

VEHICLE STORAGE
If you are storing your vehicle for more than 21 days, we
recommend that you take the following steps to mini-
mize the drain on your vehicle’s battery:
•Disconnect the Ignition-Off Draw (IOD) fuse located in
the Integrated Power Module, located in the engine
compartment. The IOD cavity includes a snap-in re-
tainer that allows the fuse to be disconnected without
removing it from the fuse block.
•As an alternative to the above steps you may discon-
nect the negative cables from both batteries.
•Any 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 switch is turned to the
RUN position. This is a normal condition.
•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 dis-
play
NO FUSE.”
