Rear Glass Removal and Storage
CAUTION:
{
If the removable rear glass is not stored
properly, it could be thrown about the vehicle
in a crash or sudden maneuver. People in the
vehicle could be injured. Whenever you store
the rear glass in the vehicle, always be sure
that it is stored securely in the midgate
storage pocket.
Do not remove the rear glass when the rear defroster is
on. If you remove the rear glass with the rear defroster
on, you may see a discharge spark coming from
the latch area.
To remove the rear glass do the following:
1. Fold the rear seats. See Rear Seat Operation on
page 1-7 for more information. The front seats
may have to be moved forward slightly to allow the
rear seats to fold completely.
Although the rear glass can be removed without
folding the rear seats, you will not be able to access
the rear glass storage pocket. Be sure to fold the
seats before removing the rear glass.
