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

Welcome to the forum @Lagross! As you drive your Corolla Cross more you should see thay mpg improve. There is a break-in period and there's some recommendations Toyota makes in the owner's manual.

For the seat height there should be a lever to help raise/lower it.

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.

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.

There has been some confusion with both of your questions. All models have height adjustable driver's seat (not your question) and no models offer a height adjustable passenger seat. An option I use when I have a passenger who is sensitive to the difference: I lower mine a bit and offer the a cushion (I got a perfect fit and comfy one at Aldi market) to match our heights.
As for the break-in period, that doesn't necessarily have a relationship to fuel economy. The sort of slight difference that people sometimes notice (never the case for me across various new cars) shouldn't exceed maybe 10%, whereas what you saw was at least 50%! So after doing the test recommended by "J", if you are not close to the numbers offered on the window sticker this should be brought to the attention of the service department, maybe when you have --if they offer-- a first check at 1000 miles or 1 month.

also check tire inflation. it could be wrong as dealers seem to over inflate tires.
also depends on what tires you have there are 3 sets they provide out the door....

the continental tires are the best winter tires out of my research that they provide.
there are 3 makes of tires they provide
1. Continental Pro Contact
2. goodyear assurance
3. firestone( just can not find a good pic of it to get name) .

keep a heads up about my posting and new posts as i read in another post that tires are inflated different from front and rear. also for awd and different trims as they are different weights. i want to get the best for the tire my mother has and the trim level. door only says so much.

also how many people are you hauling when taking numbers. for every 150lbs you loose about 1 mpg....

lastly if by 9k miles it is still like this i would get a warranty check
