SERVICE ANTILOCK BRAKES: If the SERVICE
ANTILOCK BRAKES message is displayed when you
are driving, stop as soon as possible and turn the
ignition off. Then start the engine again to reset the
system. If the message stays on, or comes back
on again while you are driving, your vehicle is in need
of service. See your GMdealer. If the anti-lock
brake system warning light is on and the regular brake
system warning light is not on, you still have brakes,
but do not have anti-lock brakes. If the regular
brake system light is also on, you do not have anti-lock
brakes and there is a problem with your brakes. See
Anti-Lock Brake System Warning Light on page3-38
and Brake System Warning Light on page3-37.
If the SERVICE ANTILOCK BRAKES message is being
displayed, your Traction Control System and the
Active Handling System will also be disabled. The Driver
Information Center will scroll three messages: SERVICE
ANTILOCK BRAKES, SERVICE TRACTION SYSTEM
and SERVICE ACTIVE HANDLING, and the instrument
cluster lights will be illuminated along with a chime.
The driver can acknowledge these messages by
pressing the RESET button. When the service message
is displayed the computer controlled systems will not
assist the driver and you should have the system
repaired by your GMdealer as soon as possible. Adjust
your driving accordingly.
SERVICE CHARGING SYSTEM: Press the RESET
button to acknowledge that you have read the message
and to remove it from the display. The message will
reappear every 10minutes until this condition changes.
You will hear multiple chimes when this message is
displayed.
If this message comes on while you are driving, you
may have a problem with the electrical charging system.
It could indicate that you have a loose or broken drive
belt or another electrical problem. Have it checked
right away by your GMdealer. Driving while this warning
message is on could drain your battery.
If you must drive a short distance with the message on,
be certain to turn off your accessories, such as the
radio and air conditioner.
SERVICE COLUMN LOCK (Manual Transmission
Only): This message may display if the system
that controls the locking and unlocking of the steering
column does not work properly. Have the vehicle towed
to your GMdealer for service.
SERVICE ELECTRICAL SYSTEM: This message
displays if an electrical problem has occurred within the
Powertrain Control Module (PCM). Have your vehicle
serviced by your GMdealer.
