To Raise Rear Seat
Raise the rear seatback and lock it into place. If interfer-
ence from the cargo area prevents the seatback from fully
locking, you will have difficulty returning the seat to its
proper position.
WARNING!
•Be certain that the seatback is securely locked into
position. If the seatback is not securely locked into
position the seat will not provide the proper
stability for child seats and/or passengers. An
improperly latched seat could cause serious injury.
•The cargo area in the rear of the vehicle (with the
rear seatbacks in the locked-up or folded down
position) should not be used as a play area by
children when the vehicle is in motion. They could
be seriously injured in a collision. Children
should be seated and using the proper restraint
system.

Wind Buffeting
Wind buffeting can be described as the perception of
pressure on the ears or a helicopter-type sound in the
ears. Your vehicle may exhibit wind buffeting with the
windows down, or the sunroof (if equipped) is in certain
open or partially open positions. This is a normal occur-
rence and can be minimized. If the buffeting occurs with
the rear windows open, open the front and rear windows
together to minimize the buffeting. If the buffeting occurs
with the sunroof open, adjust the sunroof opening to
minimize the buffeting or open any window.
Sunroof Maintenance
Use only a nonabrasive cleaner and a soft cloth to clean
the glass panel.
