Failure to follow recommended oil change intervals could contribute to this condition. The Driver?s Information Center, (DIC) ?Service brake assist? alert will activate 2-5 minutes after the vacuum level drops, and a Diagnostic Trouble Code, (DTC) will also be set. Even where this condition occurs, the hydraulic brake system remains functional but may require additional pedal force. Please understand that even if the vehicle exhibits this condition, it meets all federal motor vehicle safety standards for brake performance. Dealers are to replace the vacuum pump and vacuum pump belt. The repairs will be made at no charge to the customer.
