MAINTAINING YOUR VEHICLE 525 CAUTION! • When installing the totally integrated power module 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 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 leaving your vehicle dormant for more than 21 days you may want to take steps to protect your battery. You may: • Remove fuse #27 in the Totally Integrated Power Module (TIPM) labeled Ignition-Off Draw (IOD#1). • Or, disconnect the negative cable from the battery. • Anytime 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
