Yellow IOD – Spare CAUTION!• 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.414 MAINTAINING YOUR VEHICLE
