CAUTION!
•When installing the power distribution center
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 power distribution
center and possibly result in an 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 overload. 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 negative cable from battery.
•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.7

NOTE:Lens fogging can occur under certain atmo-
spheric conditions. This will usually clear as atmospheric
conditions change to allow the condensation to change
back into a vapor. Turning the lamps on will usually
accelerate the clearing process.
