Some of the most capable trucks and SUVs come with a four-wheel-drive system. However, it is important to know what settings to you on the four-wheel-drive system during certain situations. Here are the best times to use both Four-High and Four-Low settings on a four-wheel-drive system.
When you are driving during normal city and highway conditions with a little bit of ice, snow or gravel, you will want the vehicle to be set on the four-high or 4H mode. This allows your vehicle to have all the control it needs without compromising driving speed and fuel economy. Most of the time, you will be using the four-high setting.
When you encounter intense driving situations such as deep snow, mud, rocks or standing water, then you will want to use the four-low setting on your vehicle. This setting will give your vehicle more torque as your tires grip the surface for maximum power while spinning at a slower speed.
