A computer readable storage medium having computer executable instructions that when executed on at least one processor on a vehicle cause the at least one processor to:

• monitor by the vehicle of road conditions;
• determine if the road conditions are hazardous;
• inform an engine control unit of the hazardous road conditions;
• alter operation of the engine control unit in response to the hazardous road conditions;
• receive an indication from an operator of the vehicle indicating an intent to slow down the vehicle;
• and
• slow the vehicle based upon the altered operation of the engine control unit by applying a vacuum to increase a manifold vacuum of an engine controlled by the engine control unit.
