Maintenance schedule (Chevrolet Trailblazer 1)

1 Chevrolet TrailBlazer, Oldsmobile Bravada and GMS Envoy Maintenance Schedule

The service intervals provided in the manual are based on the assumption that the work will be performed by the vehicle owner. These are the minimum intervals recommended by the manufacturer for daily vehicle operation. If you want to keep your car in excellent technical condition at all times, you can perform some of the maintenance procedures more frequently. Frequent maintenance can only be commended because it has a positive effect on the performance of the car and also increases its selling price. If the vehicle is operated in dusty conditions, constantly towing a trailer, or frequently driving at low speeds (the engine idles a lot when driving in the city), and if short distance trips are frequently made, it is recommended to reduce service intervals.

To maintain the factory warranty, a new car must be serviced only at an authorized service station. Often, representatives of the manufacturer prepare a new car for operation at the company's expense (consult with the company representative).
