Does not service the air conditioner of your Chevrolet. BE AWARE!!!

<p>I took my Chevrolet Utility 1.4 + A/C for a 30 000 km service today, GM Zambezi informed me that the air conditioner on this vehicle must be serviced every 30 000 km and that this service is not covered under my service plan.</p> <p> </p> <p>Please explain to me why this is not mentioned in my Owner’s Handbook or Service Plan, and why was I not informed of this air conditioner service before today?</p> <p> </p> <p>Is this applicable only for this vehicle, because this is not the only Chevrolet I own and this was never mentioned to me during the services of the other vehicle?</p>
