38 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE
If the liftgate handle is pulled while the power liftgate
is opening, the liftgate motor will disengage to allow
manual operation.
The power liftgate buttons will not operate if the
vehicle is in gear or the vehicle speed is above 0 mph
(0 km/h).
The power liftgate will not operate in temperatures
below 22°F ( 30°C) or temperatures above 150°F
(65°C). Be sure to remove any buildup of snow or ice
from the liftgate before pressing any of the power
liftgate buttons.
If the power liftgate encounters multiple obstructions
within the same cycle, the system will automatically
stop and must be opened or closed manually.
If your liftgate is power closing and you put the
vehicle in gear, the liftgate will continue to power
close. However, vehicle movement may result in a
detection of an obstruction.
WARNING!
Driving with the liftgate open can allow poison-
ous exhaust gases into your vehicle. You and your
passengers could be injured by these fumes. Keep
the liftgate closed when you are operating the
vehicle.
If you are required to drive with the liftgate open,
make sure that all windows are closed and the
climate control blower switch is set at high speed.
DO NOT use the recirculation mode.
