When starting the HUMVEE to what position do you turn the ignition switch to first?

When starting the HUMVEE, you first turn the ignition switch to the "Run" position. This allows the electrical systems to engage and the glow plugs to heat up if necessary. After a few seconds, you then turn the switch to the "Start" position to crank the engine. Once the engine starts, you return the switch to the "Run" position.
