What does 2h4h4l mean for off-road vehicles?

[DeBethany]

2h4h4l represent two-wheel drive, high-speed four-wheel drive, and low-speed four-wheel drive respectively. 4h4l are two modes available in four-wheel-drive vehicles. 4h is the high-speed four-wheel-drive mode, while 4l is the low-speed four-wheel-drive mode. These two driving modes differ in terms of controlling the transmission system. Properly utilizing the four-wheel-drive modes according to terrain not only enhances the vehicle's off-road capability but also helps reduce fuel consumption to some extent. Relevant details are as follows: If driving on snowy or muddy roads, using the 4h mode is particularly suitable, as it ensures adequate traction while preventing excessive power that could cause wheel slippage. Due to its high power output, the 4l mode is not suitable for such conditions. However, when encountering uphill roads or off-road situations, the 4l mode can be used to maximize the vehicle's power. High-speed four-wheel drive is not suitable for highway driving. For part-time four-wheel-drive vehicles, the 4h and 4l modes should not be used on dry paved roads; only the 2h mode should be selected.
