The Auto LSD light pops up on your car dashboard, right?

So, you are wondering:

  • What does the light mean? 
  • What triggers it?
  • And is it safe to drive with it?

Don’t panic!

In this post, I will answer all these questions about Auto LSD and instruct you on using the system to improve your driving experience.

Let’s get into it!

What is Auto LSD?

Automatic Limited-Slip Differential (Auto LSD) is an electronic system that assists in maintaining traction. It uses the traction control system to adjust the engine performance and brake when a rear wheel experiences spinning.

Note that the Auto LSD only works in 2WD models and 2WD mode on 4WD models. 

Now, this feature is found in some Toyota models like Tacoma, Tundra, RAV4, and 4Runner.

What Does the Auto LSD Light Mean?

When the light comes on, it indicates that the Auto LSD system is activated. And the system will be operational until it detects that both wheels are again spinning at the same speed.

However, if you are in normal driving conditions but the Auto LSD light remains lit, it indicates a problem with the system, such as a faulty sensor or electrical issues.

Using a scan tool could help you diagnose faults in the system. You should have the system inspected and repaired as soon as possible. If not, the system won’t be operational to support your driving in maintaining traction.

When to Use the Auto LSD System

The system is not intended for use in all driving conditions.

You should only activate the system when one of the rear wheels is spinning due to being stuck in a ditch or navigating a rough surface. 

If the road surface is dry and there is no loss of traction, the Auto LSD system may not be needed. Driving with the operating system could even reduce performance or fuel efficiency.

How to Use the Auto LSD System

To turn off the system, you can press the ESC button again.
