Caution
Attempting to move the liftgate too
quickly and with excessive force may
result in damage to the vehicle.
Operate the liftgate manually with a
smooth motion and moderate speed. The
system includes a feature which limits the
manual closing speed to protect the
components.
Hands-Free Operation
If equipped with Hands-Free Vehicle Access,
the liftgate may be operated with a kicking
motion under the rear bumper at the
location of the projected logo. The remote
key must be within 1m (3ft) of the rear
bumper to use hands-free feature.
Splashing water may cause the liftgate to
open. Keep the remote key away from the
rear bumper detection area or turn the
liftgate mode to OFF when cleaning or
working near the rear bumper to avoid
accidental opening.
The hands-free feature will not work while
the liftgate is moving. To stop the liftgate
while in motion use one of the liftgate
switches.
The hands-free feature can be customized.
To view available settings for this feature,
touch the Settings icon on the infotainment
home page. Select Vehicle to display the
list of available options and select Comfort
and Convenience . Choose from the
following:
On-Open and Close : The kicking motion is
activated to both open and close the
liftgate.
