Assist Handles
Your vehicle may have assist handles to be used when
getting out of your vehicle. If your vehicle has assist
handles, they are located above the doors.
If your vehicle has roof-mounted side impact air bags,
there are assist handles located above both the driver’s
and front passenger’s doors.
Rear Storage Area
If your vehicle is an extended cab model, it might have
storage compartments under the rear seats.
To access the storage compartments, lift the cushion on
the bottom of the rear seats. This exposes the storage
boxes under the seat.
To open a storage box, unhook the bottom and lift the
two latches on each side of the storage box.
