Toyota Tacoma (2005–2015) Owners Manual: AUTO LSD system
The AUTO LSD system aids traction by using the traction control system to control engine performance and braking when one of the rear wheels begins to spin.
The system should be used only when one of the rear wheels spinning occurs in a ditch or rough surface.
■ System operation
The system can be used on 2WD models and in 2WD mode on 4WD models.
Press the VSC OFF switch to turn on the system.
At this time, the AUTO LSD and VSC OFF indicators will come on simultaneously.
To turn off the system, push the switch again.
If the engine is turned off while the AUTO LSD indicator is on and then restarted, the indicator will turn off automatically.
