Toyota RAV4 Auto LSD System
When driving your Toyota RAV4, you may have noticed a light on your dashboard that says, “Auto LSD.” While this may seem like a very mysterious moniker, it’s actually the indicator for a helpful system in your vehicle. So what is Auto LSD on the Toyota RAV4?

The LSD in Auto LSD stands for, “Limited-Slip Differential.” This is a traction control system that controls engine output and begins braking when one of the drive wheels begins to slip. When used in the right situation, this improves vehicle control.
When should I use Auto LSD?
Auto LSD should only be used when wheel slip occurs in very severe conditions, such as off-road or in deep snow. The Auto LSD system is intended for use only in extreme conditions. Don’t turn it on when the vehicle is in motion or when wheel-spin is occurring. It should not be left on during normal driving.
When using Auto LSD, increased steering effort may be required. You may have to be more careful to keep control while cornering. If the vehicle begins to slip while the system is engaged, the Auto LSD icon will begin flashing, indicating the system is working to control the slippage.

How do I turn on Auto LSD?
Auto LSD can be engaged by pressing the “VSC Off” switch. This button has an image that looks like the silhouette of a vehicle with two wavy lines behind the wheels, and the word “Off” beneath. When pressed, the VSC Off and Auto LSD indicators will light up on the instrument cluster, confirming that the system is engaged. To turn the system off, press the “VSC Off” button again.
Traction Control and Auto LSD
Traction Control works to optimize control during normal driving conditions. It reduces engine power when a wheel slips and applies braking to that wheel. When you turn on Auto LSD, Traction Control turns off. Auto LSD sends power to the wheel with the greatest traction, rather than reducing engine power to send the wheel forward.
Why does Auto LSD automatically shut off?
If the brakes become overheated during operation, the Auto LSD system will automatically shut off. However, it will be restored automatically after a short time. The system will also shut off automatically when the engine is turned off and will remain off when restarted.
