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. SERVICE STEERING SYS - 127: This message is displayed when a problem has been detected in the MagnasteerR variable effort steering system. Service is required. SERVICE SUSPENSION SYS - 84: This message is displayed to indicate that the suspension system is not operating properly. To correct this problem, have your vehicle serviced at your dealership. SERVICE THEFT SYSTEM - 34: This message means there is a problem in the Personalized Automotive Security System (PASS-KeyR III). A fault has been detected in the system which means that the PASS-Key III system is disabled and is not protecting the vehicle. The vehicle usually restarts, however, you may want to take your vehicle to a proper service center before turning off the engine. SERVICE TPM SYSTEM - 51: When this message is displayed, the Tire Pressure Monitor (TPM) system is not working properly. See your dealer for service. SERVICE TRANSMISSION - 100: See your dealer for repair. 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. 2-98
