With the push button start it's all computer controlled. If your GMC or mercedes has a standard ignition, you can crank them over instantly if you want and they almost always start normally, but it's better to let them heat up for a few seconds when it's cold to get better combustion initially... now ford just forces you to do this. It's also better for emissions and your DPF to do this, as starting a diesel cold will release more soot and smoke initially if your cylinder is cold.
