    Description and operation

    Description of ESP Optimum driving safety now has a name : ESP, the Electronic Stability Program. ESP recognizes critical driving conditions, such as panic reactions in dangerous situations, and stabilizes the vehicle by wheel-individual braking and engine control intervention with no needfor actuating the brake or the gas pedal...

    Repair procedures

    Inspection ESP System Bleeding This procedure should be followed to ensure adequate bleeding of air and filling of the ESC unit, brake lines and master cylinder with brake fluid...
