Trip Computer Warning Messages The following messages may appear on the center trip computer display located on the instrument panel cluster. If a message is active, it will appear on the display for 10 seconds, unless the trip computer MODE button is pressed. Pressing the MODE button will acknowledge and clear messages from the display. ALARM ACTIVATED If the ALARM ACTIVATED message comes on, it indicates that the content theft-deterrent alarm has been set off because a door, the hood, or the trunk has been opened, or that your vehicle's electrical system has been tampered with. See "How to Detect a Tamper Condition" under Content Theft-Deterrent on page 2-14 for more information. ABS (Anti-Lock Brake System) Fault If this symbol and the ABS Fault message come on, there is a malfunction of the anti-lock brake system. See your GM dealer for service. Brake If this symbol and the Brake message come on while driving and the park brake is released, a fault with the brakes is indicated. Your vehicle's brake system will still operate without ABS. The ABS Fault message will remain until the MODE button is pressed, but the symbol will remain until the condition is repaired. You should immediately stop your vehicle on the side of the road as carefully as possible. Do not proceed until satisfied that braking is possible or the condition is repaired. A warning will chime if you attempt to drive off without releasing the park brake. The Brake message will remain until the MODE button is pressed, but the symbol will remain until the condition is repaired. This message will also come on to indicate low brake fluid. 3-38
