What you should do

You can verify that a system is operating as designed by:

• Reviewing service information functional/diagnostic checks
• Examining bulletins and other service information for supplementary information
• Compare system operation to an identical vehicle

If the condition is due to a customer misunderstanding or a conflict between customer expectation and system operation, you should explain the system operation to the customer.

If the complaint is due to a case of unsatisfactory system performance, you should contact Technical Assistance for the latest information.
