Toyota Tacoma (2005–2015) Owners Manual: 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.
■ System operation
Vehicles with an automatic transmission:
Stop the vehicle, shift the shift lever to N and put the frontwheel drive control
switch in the L4 position.
Vehicles with a manual transmission: Stop the vehicle or reduce your speed to less than 2 mph (3 km/h). Depress the clutch pedal and put the front-wheel drive control switch in the L4 position.
Press the A-TRAC switch to activate the system.
At this time, the active traction control system indicator will come on.
To cancel the system, push the switch again.
When the active traction control system is operating
If four wheels spin, the slip indicator flashes to indicate that the active traction control system has been engaged.
■When the rear differential is locked (vehicles with the rear differential lock system)
The active traction control system is activated only when the vehicle speed is less than 3 mph (6 km/h).
■Sounds and vibrations caused by the active traction control system
●A sound may be heard from the engine compartment when the engine is started or just after the vehicle begins to move. This sound does not indicate that a malfunction has occurred in the system.
●Vibrations may be felt through the vehicle body and steering. It may occur when the system is operating.
■If the brake system overheats
The system will cease operation, a buzzer will sound and A-TRAC indicator blink to alert the driver. 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.
