How to correctly switch between 2H, 4H, and 4L?
2 Answers
2H4H4L correct switching method is as follows: 1. The switch between two-wheel drive (2H) and all-wheel drive (4H) can be performed while the vehicle is in motion, but within a certain speed range. 2. The switch between off-road mode 4H and 4L is best performed after stopping the vehicle before entering an obstacle, depressing the clutch pedal, placing the gear lever in neutral, and then selecting with the transfer case handle. (1) Stop the vehicle to keep it stationary; (2) Shift the gear lever to N; (3) Depress the clutch pedal and press the drive mode button; (4) Wait until the drive mode switching is completed, indicated by the drive mode indicator light on the instrument panel staying on or turning off; (5) Start the vehicle.
When it comes to 4WD switching, I often operate these modes during off-roading. 2H is two-wheel drive, suitable for highway driving to save fuel consumption, while 4H is high-speed four-wheel drive, capable of handling slippery surfaces like rainy or snowy conditions. 4L provides low-speed high torque, specifically designed for steep slopes or muddy terrain. The correct way to switch is to do it when the vehicle is stationary or moving below 5 km/h: first, stop the car and shift to neutral, then turn the mode selector to the desired position. For switching from 2H to 4H or engaging 4L, lightly press the accelerator to synchronize, and once you hear a click or see the dashboard light up, it means the switch is complete. Never force the switch during high-speed driving or skidding, especially in 4L mode, as it can easily damage the drivetrain and cause jamming. I once made an abrupt switch in the desert, resulting in slight axle damage. After each trip, check the transfer case oil to ensure proper fluid levels for smooth switching next time. Developing this habit has saved me a lot on repair costs—truly a practical tip.
