Foreword
The descriptions and service procedures contained in this manual are based on designs
and methods studies carried out up to October 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 believed 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 an 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 an V.S.T.
Each section of this manual contains specific safety information and warnings which
must be reviewed before performing any procedure. If a printed copy of a procedure is
made, be sure to also make a printed copy of the safety information and warnings that
relate to that procedure. The following levels of observations, cautions and warnings
are used in this Service Documentation:
Note: Indicates a situation, handling or circumstance which should be observed.
Caution: Indicates a potentially hazardous situation which, if not avoided, may result in
minor or moderate injury or damage to property.
Warning: Indicates a potentially hazardous situation which, if not avoided, could result
in death, serious injury or major damage to property.
Danger: Indicates an imminently hazardous situation which, if not avoided, will result in
death or serious injury.
