2002 Cadillac DeVille Owner's Manual - Page 177

SERVICE VEHICLE SOON - 3: This message is displayed when a non-emissions related powertrain malfunction occurs. Have your vehicle serviced by a technician as soon as possible. SPEED LIMITED TO 90 - 113: A failure in the suspension control system has occurred when this message appears. The Powertrain Control Module (PCM) determines the speed to which your vehicle is limited. Have your vehicle serviced if this message appears. STABILITY SYS ENGAGED - 55 : You may see the STABILITY SYS ENGAGED message on the Driver Information Center. It means that an advanced, computer-controlled system has come on to help your vehicle continue to go in the direction in which you're steering. This stability enhancement system activates when the computer senses that your vehicle is just starting to spin, as it might if you hit a patch of ice or other slippery spot on the road. When the system is on, you may hear a noise or feel a vibration in the brake pedal. This is normal. When the STABILITY SYS ENGAGED message is on, you should continue to steer in the direction you want to go. The system is designed to help you in bad weather or other difficult driving situations by making the most of whatever road conditions will permit. If the STABILITY SYS ENGAGED message comes on, you'll know that something has caused your vehicle to start to spin, so you should consider slowing down. A single chime will also sound when this message is displayed. STARTING DISABLED REMOVE KEY - 33: This message will appear when the PASS-KeyR III system detects that an improper ignition key is being used to try to start the vehicle. Check the ignition key for damage. If it is damaged, it may need to be replaced. If it is not damaged, remove the key and try to start the vehicle again. If it still does not start, try another ignition key or see your dealer for service. THEFT ATTEMPTED - 40: This message is displayed if the theft system has detected a break-in attempt while you were away from your vehicle. 2-109
