Most A-TRAC videos are just demo videos. This video is more. We explain the worst thing you can do when using A-TRAC. We explain exactly how it works, how to use it correctly, when to use it, when not to use it, and when to use Multi-Terrain Select instead.

Here are some additional notes on A-TRAC:

1. Tech Note: A-TRAC works best with constant rpms in the range of approximately 1800-2200 rpms. If you drop below 1800 rpms, the system will stop applying brake pressure and you will lose traction. If you exceed 2200 rpms, A-TRAC will release brake pressure to protect the drivetrain components.
2. Breaking Note: If you apply brakes with your foot pedal while A-TRAC is actively working, it will deactivate A-TRAC. It will work again when you release the brake pedal.
3. Traction Note: A-TRAC only works if at least one tire has traction.

We've tried to get it right in this video. If there is any incorrect information, please let us know. Cheers and have fun out there!

Please note: I have an after-market ARB air locker on my front axle. I also show a couple comparisons between MTS and the ARB air locker.

Please Note: Tacoma cannot operate MTS in 4H. However, 4Runner can operate MTS in 4H as explained below.

The Tacoma manual states:

"The Multi-terrain Select can be operated when
●The four-wheel drive control switch is in “4L” position."

That's it. That's all the manual says. Just 4L. There is no 4H MTS setting for Tacoma.

However, the 4Runner manual is different. It states: "Multi-terrain Select can be activated when
● Vehicle speed is approximately 7 mph (12 km/h) or less.
● MUD & SAND: The front-wheel drive control lever is in L4 or H4.
LOOSE ROCK, MOGUL and ROCK: The front-wheel drive control lever is in L4."

So, yes the 4Runner can operate MTS Mud&Sand setting in 4H.
