SERVICE STEERING SYS - 127: This message is displayed when a problem has been detected in the MagnasteerR variable effort steering system. Service is required. A single chime will also sound when this message is displayed. SERVICE TRANSMISSION - 100: If a problem is detected with the transaxle, this message will appear. Have your vehicle checked by your dealership. SERVICE VEHICLE SOON - 3: If a problem is detected with the transaxle, this message will appear. Have your vehicle checked by your dealership. SERV STABILITY SYS - 54: If you ever see the SERV STABILITY SYS message, it means there may be a problem with your stability enhancement system. If you see this message, try to reset the system (stop; turn off the engine; then start the engine again). If the SERV STABILITY SYS message still comes on, it means there is a problem. You should see your dealer for service. Reduce your speed and drive accordingly. A single chime will also sound when this message is displayed. STABILITY ENGAGED - 55: You may see the STABILITY 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 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 ENGAGED message comes on, you'll know that something has caused your vehicle to start to spin, so you should consider slowing down. 2-83
