MAINTAINING YOUR VEHICLE 493 CAUTION! • When installing the 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 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 storing your vehicle for more than 21 days, we recommend that you take the following steps to minimize the drain on your vehicle's battery: • Disconnect the Ignition-Off Draw fuse (IOD) fuse located in the Integrated Power Module, located in the engine compartment. The IOD cavity includes a snap-in retainer that allows the fuse to be disconnected, without removing it from the fuse block. • The electronic shift transfer case should be placed in the 4HI mode and kept in this position to minimize the battery drain. • As an alternative to the above steps you may disconnect the negative cables from both batteries. 7
