2007 Chevrolet Tahoe Owner's Manual - Page 130

It is not recommended that you drive with the liftgate open, however, if you must drive with the liftgate open, the power liftgate should be switched to manual liftgate operation - the overhead console switch set to the "Disable" position. Both the liftglass and liftgate have an electric latch. If the battery is disconnected or has low voltage, the liftglass and liftgate will not open. The liftglass and liftgate will resume operation when the battery is reconnected and charged. If the battery is properly connected and has adequate voltage, and the liftgate or liftglass still will not function, your vehicle should be taken to a dealership for service. CAUTION: (Continued) {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. CAUTION: (Continued) 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 Climate Control System on page 227 or Dual Automatic Climate Control System on page 231. • 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.
