Cracking the Code: Understanding H2 H4 and L4 in 4Runner

Published by Dustin Babich on

H2, h4, and l4 refer to the different types of four-wheel drive available in certain toyota 4runner models. H2 is two-wheel drive, h4 is full-time four-wheel drive, and l4 is low-range four-wheel drive.

Toyota 4runner is a mid-size suv that has been popular among off-road enthusiasts for decades. The car is known for its reliability and off-road capabilities. One of the reasons for this is the various four-wheel drive options available in the 4runner.

H2, h4, and l4 are three of the most common types of four-wheel drive available in certain 4runner models. H2 is two-wheel drive, which means that only the rear wheels of the car receive power from the engine. H4, full-time four-wheel drive, delivers power to all four wheels of the car continuously. L4 is low-range four-wheel drive, which is used for off-road situations that require extra power and control. In this article, we will discuss these different types of four-wheel drive and their capabilities.

The Difference Between H2, H4, And L4

H2, h4 and l4 are driving modes of a 4runner. H2 is two-wheel drive, while h4 is four-wheel drive. L4 is four-wheel drive low. Each mode affects the 4runner’s performance and capabilities. H2 is for regular driving. H4 is for driving in rough terrain.

L4 is for extreme off-roading. You can switch between modes easily. In most 4runners, you use a lever to switch. For newer models, you can adjust settings electronically. The 4runner’s design allows for maximum control while driving. H2, h4, and l4 give drivers various driving experiences.

Whether you’re driving on pavement, rock, or mud, the 4runner is designed for all terrains.

Understanding When To Use H2

H2, also known as high-range four-wheel drive, is used in a 4runner when the terrain is rough. Benefits of using h2 over h4 or l4 include better traction and less stress on the vehicle. Switching to h2 in a 4runner is easy and only requires shifting the transfer case lever.

However, it is important to only use h2 when necessary as it can cause excessive wear on the drivetrain if used incorrectly. Understanding when to use h2 can make a big difference in the performance of your 4runner on challenging terrain.


Understanding When To Use H4

H2, h4, and l4 refer to different modes on a 4runner’s four-wheel-drive system. H4 or high-four is useful in tricky conditions like off-roading on unsteady terrains, steep inclines and rocks. Using h4 provides more stability and power to all four wheels of the vehicle.

It helps to split the power between the front and the rear wheels evenly, which makes it ideal for rough terrains. When driving on slippery roads or in the snow, using h2 should suffice, as it offers a better fuel efficiency.

L4 or low-four is used for extreme conditions, like deep mud, or when towing a heavy load up a steep incline. To switch to h4 in a 4runner, one needs to be driving under 62mph and shift the vehicle into neutral before shifting to h4.

Understanding When To Use L4

Understanding when to use l4 in a 4runner is crucial for off-roading enthusiasts. L4, or low 4-wheel drive, is utilized when navigating through steep terrain, crossing deep ditches, or when going uphill on slippery surfaces. Compared to h2 or h4, l4 provides maximum torque and power to all 4 wheels, making it the ideal choice for challenging trail conditions.

If you’re encountering significant obstacles on the trail, the benefits of l4 over h2 or h4 are unmatched. To switch to l4, ensure you’re in neutral, press the brake, and shift the transfer lever to l4. When the transfer lever light stops blinking, you’re in l4 mode.

With these tips, you’ll help ensure your safety and maximize your vehicle’s performance on even the toughest off-road paths.
