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.
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.
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.
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” underContent Theft-Deterrent on page 2-14
for more information.
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.
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.
