Servicing Specifications 1•3

The maintenance intervals in this manual
are provided with the assumption that you,
not the dealer, will be carrying out the work.
These are the minimum maintenance intervals
recommended by the manufacturer for
vehicles driven daily. If you wish to keep your
vehicle in peak condition at all times, you may
wish to perform some of these procedures
more often. We encourage frequent
maintenance, because it enhances the
efficiency, performance and resale value of
your vehicle.
If the vehicle is driven in dusty areas, used
to tow a trailer, or driven frequently at slow
speeds (idling in traffic) or on short journeys,more frequent maintenance intervals are
recommended. Vauxhall recommend that the
service intervals are halved for vehicles that
are used under these conditions.
When the vehicle is new, it should be
serviced by a factory-authorised dealer
service department, to preserve the factory
warranty.
Maintenance is essential for ensuring safety
and for getting the best in terms of
performance and economy from your vehicle.
Over the years, the need for periodic
lubrication -oiling, greasing, and so on -has
been drastically reduced, if not eliminated.
This has unfortunately tended to lead someowners to think that because no action is
required, components either no longer exist,
or will last for ever. This is certainly not the
case; it is essential to carry out regular visual
examination comprehensively to spot any
possible defects at an early stage before they
develop into major expensive repairs.
The following service schedules are a list of
the maintenance requirements, and the
intervals at which they should be carried out,
as recommended by the manufacturers.
Where applicable, these procedures are
covered in greater detail near the beginning of
each relevant Chapter.
