{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 previously in this section.
To access the fuses, push in the two tabs, then lift the
cover off.
Your vehicle may not have all the fuses listed next.
