Foreword
The descriptions and service procedures contained in this manual are based on designs and methods studies carried out up to May 06. The products are under continuous development. Vehicles and components produced after the above date may therefore have different specifications and repair methods. When this is judged to have a significant bearing on this manual, supplementary service bulletins will be issued to cover the changes. The new edition of this manual will update the changes. In service procedures where the title incorporates an operation number, this is a reference to V.S.T. (Volvo Standard Times). Service procedures which do not include an operation number in the title are for general information and no reference is made to V.S.T. The following levels of observations, cautions and warnings are used in this Service Documentation: Note: Indicates a procedure, practice, or condition that must be followed in order to have the vehicle or component function in the manner intended. Caution: Indicates an unsafe practice where damage to the product could occur. Warning: Indicates an unsafe practice where personal injury or severe damage to the product could occur. Danger: Indicates an unsafe practice where serious personal injury or death could occur.
