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.
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.
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
