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.
WARNING!
Do not attempt to change a tire on the side
of the vehicle close to moving traffic. Pull
far enough off the road to avoid the danger
of being hit when operating the jack or
changing the wheel.
Being under a jacked-up vehicle is
dangerous. The vehicle could slip off the
jack and fall on you. You could be crushed.
Never put any part of your body under a
vehicle that is on a jack. If you need to get
under a raised vehicle, take it to a service
center where it can be raised on a lift.
Never start or run the engine while the
vehicle is on a jack.
The jack is designed to be used as a tool for
changing tires only. The jack should not be
used to lift the vehicle for service purposes.
The vehicle should be jacked on a firm level
surface only. Avoid ice or slippery areas.
