Toyota 4Runner: AUTO LSD system (2WD models)
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 wheel spinning occurs in a ditch or rough surface.
System operation
Press the VSC off switch to turn on the system.
At this time, the “AUTO LSD” and VSC off indicators will come on.
To turn off the system, press the switch again.
When the AUTO LSD system is operating
If the rear wheels spin, the slip indicator flashes to indicate that the AUTO LSD system has controlled the spinning of the rear wheels.
If the engine is turned off and restarted
The AUTO LSD system and the indicators are automatically turned off.
If the brake system overheats
The system will cease operation and a buzzer will sound to alert the driver.
At this time, the “AUTO LSD” indicator will flash and the “TRAC OFF” indicator will come on. Stop the vehicle in a safe place. (There is no problem with continuing normal driving.)
The system will be automatically restored after a short time.
CAUTION
To avoid an accident
• Do not use the AUTO LSD system in conditions other when wheel spinning occurs in a ditch or rough surfaces.
A much greater steering effort and more careful cornering control will be required.
• Do not drive with the AUTO LSD system continuously turned on.
NOTICE
Activating while driving
Never activate the AUTO LSD system if the wheel is slipping.
Stop the slipping or spinning before activating.
Active traction control system
The active traction control system automatically helps prevent the
spinning of 4 wheels when the vehicle is started or accelerated on slippery road
surfaces.
