Power Liftgate Operation
Warning
You, or others, could be injured if
caught in the path of the power
liftgate. Make sure there is no one
in the way of the liftgate as it is
opening and closing.
If equipped with a power liftgate, the
switch is on the overhead console.
The vehicle must be in P (Park).
There are three modes:
MAX: The liftgate power opens
to the maximum height.
3/4: The liftgate power opens to
a reduced height that can be set
from 3/4 to fully open. Use this
setting to prevent the liftgate
from opening into overhead
obstructions such as a garage
door or roof-mounted cargo
during power operation. The
liftgate can still be manually
opened all the way.
OFF: The liftgate only operates
manually in this position.
To power open or close the liftgate,
select MAX or 3/4 mode.
