What is DAC on Lexus GX?

DAC on Lexus GX
The DAC (Downhill Assist Control) system on the Lexus GX is designed to help prevent excessive speed on steep downhill slopes. It operates when the vehicle is traveling under 15 mph (25 km/h) and the four-wheel drive control switch is in the L4 position. When the DAC system is in operation, the downhill assist control indicator light comes on, the slip indicator light flashes, and the stop lights/high mounted stop lights are lit. The DAC switch can be shifted to OFF while the system is in operation to gradually cease its operation, and the indicator light will flash until the system is fully off. To start the system again, the DAC switch should be shifted to ON while the downhill assist control indicator is flashing.
Please note that the DAC system is available on specific Lexus GX models and may not be present on all trims or model years. For more detailed information about the DAC system on a specific Lexus GX model, it is recommended to refer to the owner’s manual or contact a Lexus dealership.
