Liftgate/Liftglass - GMC 2008 Yukon Denali Owner's Manual

Liftgate/Liftglass

CAUTION:
{
It can be dangerous to drive with the liftglass or
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.
If you must drive with the liftglass or liftgate
open, or if electrical wiring or other cable
connections must pass through the seal
between the body and the liftglass or 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 Dual
Automatic Climate Control System on
page 3-23.
CAUTION: (Continued)
