Practical Applications of L4L, H4L, and H4F
After understanding the specifics, it’s equally crucial to discern when to use these systems effectively. Knowledge is power, and knowing how to apply this knowledge can significantly enhance your off-road experiences. For example, the L4L mode is your go-to choice when you’re navigating rocky terrain, steep inclines, and deep mud.

As long as you are in H4, there is no limit to speed. While there is no need to be going too fast, it is possible to attain greater speed in this gear. However, it is advisable to not go beyond 30 or 40mph. to shift to L4, you need to stop and be neutral.
Shifting between the 2-wheel drive and 4-wheel drive as well as locking and unlocking the center differential can all be done while driving. Some drivers confirm that it is easier to engage their 4wd while driving. However, you will be required to be traveling at a speed less than 50mph to lock it in 4-wheel drive.
If you are in full-time 4WD, you can drive as fast as your 4runner is capable of. However, when you have it locked in 4hi, it is advisable not to exceed 50mph. Often, anytime you come across a road that is slippery enough to require 4WD, it is not safe. Hence, avoid high speeds.
