Traction Control System (TCS)  
The Traction Control System (TCS) enhances traction and safety  
by controlling engine torque and braking. When the TCS detects  
driving wheel slippage, it lowers engine torque and operates the  
brakes to prevent loss of traction.  
This means that on a slick surface, the engine adjusts automati-  
cally to provide optimum power to the drive wheels, limiting  
wheel spin and loss of traction.  
The warning light turns on when the system has a malfunction.  
Refer to Contact Your Toyota Dealer and Have Vehicle Inspected on  
P. 493.  
To turn off the TCS, press the DSC OFF switch (P. 219).  
WARNING  
Do not rely on the Traction Control System (TCS) as a substitute for  
safe driving  
The Traction Control System (TCS) cannot compensate for unsafe and  
reckless driving, excessive speed, tailgating (following another vehicle too  
closely), and hydroplaning (reduced tire friction and road contact because  
of water on the road surface). You can still have an accident.  
Use snow tires or tire chains and drive at reduced speeds when roads  
are covered with ice and/or snow  
Driving without proper traction devices on snow and/or ice-covered roads is  
dangerous. The Traction Control System (TCS) alone cannot provide ade-  
quate traction and you could still have an accident.

TCS/DSC Indicator Light  
This indicator light stays on for a  
few seconds when the ignition is  
switched ON. If the TCS or DSC is  
operating, the indicator light  
flashes.  
If the light stays on, the TCS, DSC or the brake assist system may  
have a malfunction and they may not operate correctly. Take your  
vehicle to your Toyota dealer.

In addition to the indicator light flashing, a slight lugging sound will come  
from the engine. This indicates that the TCS/DSC is operating properly.  
On slippery surfaces, such as fresh snow, it will be impossible to achieve  
high rpm when the TCS is on.
