drive and mutimode fourwheel  
drive models)  
NOTICE  
Do not use the “AUTO LSD” system  
in conditions other than the above. A  
much greater steering effort and more  
careful cornering control will be re-  
quired.  
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.  
To turn on the system, briefly push the  
“VSC OFF” switch. At this time, the  
“AUTO LSD” indicator and slip indica-  
tor lights will come on.  
To turn off the system, briefly push the  
“VSC OFF” switch again and the “AUTO  
LSD” and slip indicator lights will go off.  
This system is used only when wheel

If the engine is turned off while the  
“AUTO LSD” and slip indicator lights are

When you push and hold the “VSC OFF”  
switch for 3 seconds or more with the  
vehicle stopped, turn off the vehicle stabil-  
ity control system. See “Vehicle stability  
control system” on page 183 in this Sec-  
tion.  
The brake actuator temperature increases  
during continuous operation of the “AUTO  
LSD” system, the traction control system  
and the vehicle stability control system  
such as on slippery roads. If the brake  
actuator temperature becomes too high  
while any of the systems is operating, a  
buzzer will start to sound intermittently to  
indicate that the “AUTO LSD” system can  
no longer operate. In this case, immedi-  
ately stop your vehicle at a safe place.  
If the system continues to operate, the  
buzzer sound changes from intermittent to  
continuous.

The slip indicator light blinks when the  
system is controlling the spinning of the  
rear wheels.  
At the time the slip indicator light will  
come on and the “AUTO LSD” system  
temporarily stops operating in order to  
protect the brake actuator. (Although the  
“AUTO LSD” system does not operate, it  
is no problem to continue driving.) The  
system will be automatically restored after  
a short time and the slip indicator light  
goes off.
