BATTERY NOT CHARGING If the battery is not charging during operation, this message will appear on the DIC. Driving with this problem could drain your battery. Have the electrical system checked as soon as possible. Pressing the select button will acknowledge this message and clear it from the DIC display. REDUCED BRAKE POWER If your vehicle has vacuum assist power brakes, this message will be displayed and you may notice that the brake pedal is harder to push and it will take longer to stop. You may also hear a motor running and feel a slight vibration in the brake pedal or steering wheel when you apply or release the brake pedal even if your foot is not on the brake pedal. This indicates that the Supplemental Brake Assist system is working to maintain braking power. If you are braking lightly, you may not notice any difference in the operation of your brakes. This message may also be displayed for brief periods if you are driving at higher elevations and are pumping your brakes or braking hard. The message may clear after you've lifted your foot from the accelerator pedal an allowed the vehicle to coast in gear or after you have driven down to a lower elevation. This is a normal operation of your brake system and does not require that the brake system be serviced. However, if the message does not clear, your brake system needs service. While the message is displayed you will notice that the brake pedal is harder to push and it will take longer to stop. See Brake System Warning Light on page 3-37 SERVICE AIR BAG If there is a problem with the air bag system, this message will be displayed on the DIC. Have a qualified technician inspect the system for problems. Pressing the select button will acknowledge this message and clear it from the DIC display. SERVICE BRAKE SYSTEM If a problem occurs with the brake system, this message will appear on the DIC. If this message appears, stop as soon as possible and turn off the vehicle. Restart the vehicle and check for the message on the DIC display. If the message is still displayed, or appears again when you begin driving, the brake system needs service. 3-58
