Toyota Tacoma (2005–2015) Owners Manual: Downhill Assist Control system
The downhill assist control system helps to prevent excessive speed on steep downhill descents.
■ System operation
The system will operate when the vehicle is traveling under 15 mph (25 km/h) and the front-wheel drive control switch is in the L4 position.
Press the DAC switch. The indicator will come on, and the system will operate.
With the vehicle traveling at a speed of 15 mph (25 km/h) or less, release your foot from the accelerator or brake pedal to activate the system.
When the system is in operation, the slip indicator will flash, and the stop lights/high mounted stop light will come on. A sound may also occur during the operation. This does not indicate a malfunction.
■ Turning off the system
Press the DAC switch while the system is in operation. The indicator will flash as the system gradually ceases operation, and will turn off when the system is fully off.
Pressing the DAC switch while the indicator is flashing will start the system again.
■Operating tips
The system will operate when the shift lever is in a position other than P.
However, to make effective use of the system it is recommended that the shift lever be shifted to 2 or L.

●The front-wheel drive control switch is in the H2 or H4 position.

■System malfunction
