Mercury 2005 Mountaineer Owner's Manual page 90

The liftgate door and window should be closed before driving. If not,
possible damage may occur to your vehicle.
Always close liftgate window before opening liftgate. Liftgate
glass and liftgate should never be open at the same time. Failure
to observe this warning may result in personal injury or damage to
your vehicle.
Make sure the liftgate door and/or window are closed to prevent
exhaust fumes from being drawn into the vehicle. This will also
reduce the risk of passengers and cargo falling out.
CARGO COVER (IF EQUIPPED)
Your vehicle may be equipped with a cargo area cover that covers the
luggage compartment of your vehicle.
To install the cover:
Push both ends of the cover into the
depressions (right side first) in the
trim panels behind the second row
seat.
To reduce the risk of
injuries, the cargo area
cover must be properly installed
on the rear trim panels.
Do not place any objects on the cargo area cover. They may
obstruct your vision or strike occupants of the vehicle in the
case of a sudden stop or collision.
Cargo management system
The cargo management system consists of storage compartments located
in the floor of the rear cargo area.
