Active traction control system  
(fourwheel drive models)  
The active traction control system auto-  
matically helps prevent the spinning of  
4 wheels when the vehicle is started or  
accelerated on slippery road surfaces.  
D You may feel vibration or noise in your  
vehicle, caused by operation of the  
brakes. This indicates the system is  
functioning properly.  
When the engine switch is turned to “ON”,  
the system automatically turns on.  
The slip indicator light comes on for a few  
seconds when the engine switch is turned  
to “ON”. If the indicator light does not  
come on when the engine switch is turned  
on, contact your Toyota dealer.  
CAUTION  
Under certain slippery road condi-  
tions, full traction of the vehicle and  
The brake actuator temperature increases  
during continuous operation of the active  
traction control system, the vehicle stabil-  
ity control system, the downhill assist con-  
trol system and the hillstart assist control  
system such as on slippery roads. If the  
brake actuator temperature becomes too  
high while any of the systems is operat-  
ing, a buzzer will start to sound intermit-  
tently to indicate that the active traction  
control system can no longer operate. In  
this case, immediately stop your vehicle at  
a safe place.  
power to the  
4
wheels cannot be  
maintained, even though the traction  
control system is in operation. Do not  
drive the vehicle under any speed or  
maneuvering conditions which may  
cause the vehicle to lose traction  
control. In situations where the road  
surface is covered with ice or snow,  
your vehicle should be fitted with  
snow tires or tire chains. Always  
drive at an appropriate and cautious  
speed for the present road condi-  
tions.  
NORMAL DRIVING MODE  
Leave the system on during the ordi-  
nary driving so that it can operate  
when needed.  
You may hear  
a
sound in the engine  
compartment for a few seconds when the  
engine is started or just after the vehicle  
begins to move. This means that the ac-  
tive traction control system is in the self−  
check mode, but does not indicate a mal-  
function.  
If the system continues to operate, the  
buzzer sound changes from intermittent to  
continuous.  
(The  
continuous  
buzzer  
sounds for about 3 seconds.)  
When the active traction control system is  
operating, the following conditions occur:  
D The system controls the spinning of the  
4 wheels. At this time, the slip indica-  
tor light blinks.

At the time, the slip indicator light will  
come on and the active traction control  
system temporarily stops operating in or-  
der to protect the brake actuator. (Al-  
though the active traction control system  
does not operate, there is no problem to  
continue your driving.) The system will be  
automatically restored after a short time  
and the slip indicator light goes out.  
Depressing the brake pedal repeatedly  
may turn on the light. It is normal if it  
goes out after a few seconds.  
If the “VSC OFF” warning light flashes  
while driving, the active traction control  
system does not work. However, as nor-  
mal braking operates when being applied,  
there is no problem to continue your driv-  
ing.  
In the following cases, contact your Toyota  
dealer:  
D The warning light does not come on  
after the engine switch is turned to  
“ON”.

D Vehicle stability control system  
D Downhill assist control system  
D Hillstart assist control system  
When the system is normal and the en-  
gine switch is turned to “ON”, the warning  
light will come on and will go off after a  
few seconds.  
It is not a malfunction that the warning  
light may stay on for 60 seconds after the  
engine switch is turned to “ON”.
