H2 Mode. The first mode we will discuss is the classic mode used for everyday driving– the H2 mode. This is the mode that your vehicle should be in when you first purchase it. H2 means high speed, two-wheel drive. Two-wheel drive means that only two of your wheels are receiving power, and the other two are just along for the ride.
Example. Headings do not have to appear in section elements, as shown in this example. If they do, however, because these section elements are semantically regarded as sub-sections of their parent, their content could begin with h1 elements and these headings would be regarded as sub-headings. It is quite valid to use h2 elements as show above
