I have the same model and serviced it early before a trip at 17,000 now done 40,000 so that is 23,000 rang dealer he said they recommend service at max of 25,000 but they had had some people wait till notified at 35 to 40k.
Apparently the service warnings operate on the efficiency of the vehicle not the quality of the oil, so if you do mainly longer runs will have longer service intervals. Sonds common sense to me 25,000 max interval
