WARNING: Driving a vehicle with the brake system warning
light on is dangerous. A significant decrease in braking
performance may occur. It takes you longer to stop the vehicle. Have
the vehicle checked by your authorized dealer. Driving extended
distances with the parking brake engaged can cause brake failure and
the risk of personal injury.
Charging System
It illuminates when the 12–volt battery is not charging properly.
Contact an authorized dealer as soon as possible. This indicates
a problem with the electrical system or a related component.
Check Fuel Cap (gasoline engine only)
It illuminates when you may not have installed the fuel cap
properly. Continued driving with this light on may cause the
service engine soon warning indicator to come on.
Check Suspension
It illuminates when you press the air suspension dump switch.
Check Transmission (Allison automatic transmission only)
It illuminates while driving if a transmission problem exists;
shifting may be restricted. Depending on the severity of the
problem, the shifter’s digital read-out may turn blank.
On MD 3000 series transmissions, operation may continue in order to
reach service assistance. The control unit may not respond to shift
selector requests, since there are operating limitations on the
transmission (such as upshift and downshift restrictions). Direction
changes do not occur.
Cruise Control
It illuminates when you switch this feature on.
