DIC Warnings and Messages Other warning messages may appear in the DIC display. For Canadian drivers,in addition to the DIC message your DIC will display EXP with a number after it which reflects thefollowing messages: EXP (Export ID) 23 I Warning Message DOOR AJAR 1 SERVICE STABILITY SYSTEM - 54: If you ever see the SERVICE STABILITY SYSTEM 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 SERVICE STABILITY SYSTEM message still comes on, it means there is a problem. You should see your dealer for service. Reduce your speed and drive accordingly. STABILITY SYSTEM ACTIVE - 55: You may see the STABILITY SYSTEM ACTIVE 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. I 140 ITIRE PRESSURE LOW -~ The EXP codes are used to make translation from I 3-51
