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) in certain
open or partially open positions. This is a normal occur-
rence and can be minimized. If the buffeting occurs with
the sunroof open, adjust the sunroof opening to minimize
the buffeting.
LIFTGATE
To open the liftgate, pull up on the handle and lift.
Manually unlocking the vehicle doors with the plunger
or a key in the lock cylinder will not unlock the liftgate.
WARNING!
Driving with the liftgate open can allow poisonous
exhaust gases into your vehicle. You and your pas-
sengers could be injured by these fumes. Keep the
liftgate closed when you are operating the vehicle.
