Firstly, the climate system should be turned on after the power unit has worked a little. Secondly, you need to turn off the cooling of the passenger compartment at least a minute before the engine stops, or even earlier, so that the engine runs without load. Thirdly, in order to avoid colds, it is necessary to adjust the cooling of the interior so that the temperature difference between the environment and the car does not exceed ten degrees. Fourth, the engine is less stressed when the climate control is in use while it is running at higher revs. For this reason, in order to effectively cool the passenger compartment while driving, it is recommended to downshift or move a little faster. If the automaker makes any specific recommendations for using the system, it would be correct to adhere to them.
