Foreword
The descriptions and service procedures contained in this manual are based on designs
and methods studies carried out up to November 2003.
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:
