GMC 2007 Acadia - Manual (Page 110)

The liftgate has an electric latch. If the battery is
disconnected or has low voltage, the liftgate
will not open. The liftgate will resume operation
when the battery is reconnected and charged.
If the battery is properly connected and has
adequate voltage, and the liftgate still will not
function, your vehicle should be taken to a
dealership for service.

{ CAUTION:
It can be dangerous to drive with the
liftgate open because carbon monoxide
(CO) gas can come into your vehicle. You
cannot see or smell CO. It can cause
unconsciousness and even death.
CAUTION: (Continued)
CAUTION: (Continued)
If you must drive with the liftgate open, or
if electrical wiring or other cable
connections must pass through the seal
between the body and the liftgate:
• Make sure all other windows are shut.
• Turn the fan on your heating or
cooling system to its highest speed
with the recirculation mode off. That
will force outside air into your vehicle.
See Climate Control System on
page 199.
• If you have air outlets on or under
the instrument panel, open them all
the way.
• If your vehicle has a power liftgate,
disable the power liftgate function.
See Power Liftgate on page 110.
Your vehicle may have a power liftgate. The
vehicle must be in PARK (P) to use the power
feature.
