Power Liftgate Operation
On vehicles with a power liftgate,
the vehicle must be in P (Park) to
use the power feature. The taillamps
flash when the power liftgate
moves.
If you open the liftgate
without checking for overhead
obstructions such as a garage
door, you could damage the
liftgate or the liftgate glass.
Always check to make sure the
area above and behind the liftgate
is clear before opening it.
Choose the power liftgate mode by
turning the dial on the switch to
either the 3/4 or MAX position.
Press to open or close the
liftgate.
See Liftgate on page 2 9.
