SERVICE AIR BAG This message will display when there is a problem with the airbag system. Have your vehicle serviced by your GM dealer immediately. See Airbag Readiness Light on page 3-27 for more information. SERVICE POWER STEERING This message will display when a problem is detected with the power steering system. When this message is displayed, you may notice that the effort required to steer the vehicle increases or feels heavier, but you will still be able to steer the vehicle. Have your vehicle serviced by your GM dealer immediately. SERVICE BATTERY CHARGING SYSTEM This message will display when there is a problem with the generator and battery charging systems. Driving with this problem could drain your battery. Turn off all unnecessary accessories. Stop and turn off the vehicle as soon as it is safe to do so. Have the electrical system checked by your GM dealer immediately. SERVICE THEFT SYSTEM This message will display when there is a problem with the theft-deterrent system programmed in the key. A fault has been detected in the system which means that the system is disabled and it is not protecting the vehicle. The vehicle usually restarts; however, you may want to take the vehicle to your GM dealer before turning off the engine. See PASS-Key® III+ Operation on page 2-19 for more information. SERVICE BRAKE SYSTEM This message will display when service is required on the brake system. Have the brake system serviced by your GM dealer as soon as possible. The brake system warning light will also appear on the instrument panel cluster when this message appears on the DIC. See Brake System Warning Light on page 3-30. SERVICE TIRE MONITOR SYSTEM If your vehicle has a Tire Pressure Monitor (TPM) system, this message will display if a part on the system is not working properly. If you drive your vehicle while any of the four sensors are missing or inoperable, the warning will come on in about 10 minutes. A sensor would be missing, for example, if you put different wheels on your vehicle without transferring the sensors. If the warning comes on and stays on, there may be a problem with the TPM. See your GM dealer. 3-50
