Vehicle Messages
Messages displayed on the DIC indicate the status of the vehicle or some action may be needed to correct a condition. Multiple messages may appear one after another.
The messages that do not require immediate action can be acknowledged and cleared by pressing
(Set/Reset) or the trip odometer reset stem.
The messages that require immediate action cannot be cleared until that action is performed.
All messages should be taken seriously and clearing the message does not correct the problem.
The following are the possible messages and some information about them.
If the vehicle has a diesel engine, see the Duramax® diesel supplement for more information.
