All About Four-Wheel-Drive: 4H vs 4L

Here at BMW of Anchorage in Anchorage, AK, we want to help you get the most out of your off-road vehicle. A four-wheel-drive system is used to give your vehicle more grip, and it comes in handy when you're climbing a steep hill or driving on off-road terrain, but when do you use 4H vs 4L? Let's find out.

The low-range four-wheel-drive mode is made to handle serious conditions, which may include crossing water, climbing rocks, driving on icy roads, or driving on steep grades. When you're using the 4L setting, it's best to keep your driving speed under 40 mph because you're applying more torque for maximum traction and power, which means the wheels will turn more slowly than usual.

4H (4-High) lets you drive at faster speeds. When you're in 4H, you can drive up to 55 mph in most situations. This setting is typically used more than 4L and is mostly used on muddy, rocky, and slippery roads.
