Schedule of current maintenance (Opel Astra G)

The intervals for routine vehicle maintenance specified in this Section are designed for the independent performance of all necessary procedures by the vehicle owner. The duration of the intervals was determined based on the assumption that the vehicle is used on a daily basis. In order to constantly maintain the vehicle in peak condition, some of the procedures may be performed more frequently at the owner's request. The authors of this Manual are confident that maximum efficiency from the vehicle's power unit and other components and systems can only be achieved if the owner takes a conscientious attitude to the care of his vehicle. One should also not forget about the need to maintain the marketable appearance of the vehicle in case of its resale.

When operating the vehicle in very dusty areas, intense urban traffic (frequent short trips), and when frequently towing a trailer, the intervals between routine maintenance procedures should be reduced to a minimum if possible.

Maintenance of a new vehicle, in order to avoid violation of the manufacturer's warranty obligations, must be carried out at the manufacturer's authorized service station.

When operating the vehicle under stressful conditions, perform all procedures marked with an asterisk twice as often.
