2007 Cadillac STS Owner's Manual - Page 101

Lockout Protection Your vehicle can be programmed to sound the horn three times and unlock the driver's door when all doors are closed and there is a keyless access transmitter inside the interior of the vehicle. When the driver's door is reopened, the key in reminder chime will sound continuously. The vehicle will remain locked only when at least one transmitter has been removed from the vehicle and both doors are closed. See Vehicle Personalization on page 148. Trunk {CAUTION: It can be dangerous to drive with the trunk lid 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 trunk lid open or if electrical wiring or other cable connections must pass through the seal between the body and the trunk lid: • Make sure all other windows are shut. • Turn the fan on your heating or cooling system to its highest speed and select the control setting that will force outside air into your vehicle. See Climate Control System. • If you have air outlets on or under the instrument panel, open them all the way. See Engine Exhaust on page 125. 101
