1. As stated previously, if the tire pressure warning light is on (whether it is cold or hot out) means that your tires are not inflated properly. It is possible to disable this with some programmers.
2. You can't just turn off the light. If you don't want to run with MDS (deactivating 4 cylinders to improve fuel economy, the cause of the light coming on) you can press the "Tow/Haul" button. This will turn off MDS.
