Breaking in a new engine (Cruise Control)

Asked by May 19, 2018 at 04:39 PM about the 2018 Kia Forte LX

Question type: General

I have a Kia forte 2018 and I read online (but
nowhere on the user manual) that you shouldn't
use the cruise control in the first 1,000  miles.
However, I did this on the first day driving home
from out of town. Is there a chance I could have
messed up my new car?

No, they don't want you to use the cruse control cause of the drive time protocols, during the very first 1000 miles the computer is learning about how you drive, engaging the cruse is letting the control unit control the throttle and is not providing any user input, the processor is looking for slight changes in the TPS readings that comes by you driving even though you think your foot is steady there are movements, other factors are temperature, speed, road conditions, acceleration and deceleration, braking, etc.

oh ok, so I haven't messed up anything far as the engine goes? I didn't use it the whole way home, just for about 30 minutes and the rest of the 1000 miles have been driving with my foot on the pedal. It's my first new car so I want to make sure I take care of it and don't do anything to shorten the life of the engine, thanks!


You have one of the vehicles that require a very ridged maintenance schedule to get any kind of longevity out at all. Oil and filter changes every 3000 miles, if and automatic transmission service at 15000 mile intervals, coolant changes every other year as well as the thermostat, complete tune up at 60000 mile intervals and a timing belt at 80000 intervals. I know this goes against what the owners manual shows but if you want to get the most out if it follow the plan listed above. There will be other problems as the mileage creeps up like brakes, oil leaks, suspension and so on. Just remember maintenance is the key. HTH
