First, I would fill the tank yourself (it may not have been completely filled by the dealer) and reset the trip odometer. Then, drive a few hundred miles in mixed driving conditions (city, highway, etc.) then refill the tank and check the mileage. Do the math yourself and check it against the car's trip computer; computers are always accurate.Hi everyone. After ordering a CC in January, finally received it mid April. Have never bought a car without a test drive so this whole process is new to me. Overall I like the car but there are two concerns for me. My car came with a full tank of gas and now I just filled it up. The mileage states it is getting about 17-18 mpg. Some people have told me there is a "break in " period for the engine before you see the great mileage. Is this true and has anyone experienced this also?
Second the passenger seat seats very low. I do not see anyway to raise it. Am I missing something? Other than I love the car. I got silver.d
Yes, it may take up to 1,000 miles to break in the engine though break in isn't as necessary as it was 40-50 years ago; modern engine tolerances are much better. Mileage should improve with time. As they say, YMMV.
Second, which trim do you have. L, LE or XLE? Check the manual for adjusting the seat height.
