a short that could damage the battery and or

from any of the covered parts, and do not store
anything under the seats.

{CAUTION:
A safety belt that is not properly routed
through the seat cushion or is twisted will
not provide the protection needed in a
crash. If the safety belt has not been
routed through the seat cushion at all, it
will not be there to work for the next
passenger. The person sitting in that
position could be badly injured. After
reinstalling the seat cushion, always
check to be sure that the safety belts are
properly routed and are not twisted.
1. Buckle the center passenger position safety
belt, then route the safety belts through the
proper slots in the seat cushion. Do not let the
safety belts get twisted.
2. Slide the rear of the cushion up and under the
seatback so the rear-locating guides hook into
the wire loops on the back frame.3. With the seat cushion lowered, push rearward
and then press down on the seat cushion until
the spring locks on both ends engage.
4. Check to make sure the safety belts are
properly routed and that no portion of any
safety belt is trapped under the seat.
Also make sure the seat cushion is secured.
Rear Underseat Fuse Block
There is a fuse block located under the rear seat
on the driver’s side and passenger’s side of
the vehicle. The rear seat cushion must be
removed to access the fuse blocks. See
“Removing the Rear Seat Cushion” listed
