DAC in Lexus GX460
The DAC (Downhill Assist Control) in the Lexus GX460 is a system designed to assist in maintaining a controlled speed when driving downhill on steep slopes. It helps prevent excessive speed and provides additional braking support to ensure a safe descent. The DAC system operates when the vehicle is traveling under 15 mph (25 km/h) and the four-wheel drive control switch is in the L4 position. By shifting the “DAC” switch to ON, the system engages and limits the vehicle’s acceleration. It is important to note that the DAC system should be turned off when not in use.
The DAC system works in conjunction with the vehicle’s four-wheel drive control lever, which needs to be in the L (low) position for the DAC to function. When driving down a hill with the four-wheel drive control lever in the L position, pushing the DAC switch helps limit the vehicle’s acceleration. This allows the driver to descend at a constant speed, especially when traveling at a speed of 25 km/h (15 mph) or less.
The DAC system is a valuable feature for off-road driving and provides added control and safety when navigating steep downhill slopes. It helps prevent the brakes from overheating and reduces the risk of losing control while descending on challenging terrains.
Please note that the DAC system is specific to the Lexus GX460 model and may not be available in other Lexus models or vehicles from different manufacturers.
I hope this information clarifies the functionality of the DAC system in the Lexus GX460. Let me know if you have any further questions!

What is the DAC in 4WD?
The DAC light comes on to let you know the system is operational. As you head down the hill, Downhill Assist Control brakes individual wheels to maintain control and a safe rate of descent without any driver intervention.
Should DAC be on or off?
Really the only real concerns I can think of would be if it’s a dac with a tube output stage (in that case I would not suggest leaving it on all the time to preserve tube life), or if you are super concerned about power surges or something of that sort.
Put the transmission in L or low gear slow to less than 15 miles per hour if you’re already moving. Press the DAC button. And keep your feet off the accelerator. And brake. The downhill assist icon.
Is it OK to leave DAC on?
Yes, it’s perfectly fine to have the DAC constantly powered on. It draws little power and it will not damage the DAC.
Can I use a DAC in my car?
Many factory radios have the AUX input option, too. So, you can connect a portable high-res player or your phone using a high-res music player app, like VOX or JetAudio, and enjoy. Using a car stereo’s AUX input with a smartphone DAC, like AudioQuest’s Dragonfly Cobalt, is a great way to get solid sound.
Should I turn off my DAC?
In some older gear on/off cycles could shorten the lifespan of some capacitors, but modern components don’t wear out like that. DACs being always on has no benefit either. They’re generally made of solid state components which don’t need to charge or warm.
How do I turn off DAC?
So now to disengage the dac. Of course it’s quite simple you just hit the button. And the light will be off in the dash. Again. And it’s completely disabled.
What is the DAC mode in a car?
DAC in a car stands for “Downhill Assist Control.” It’s a special safety system that helps vehicles go downhill in a safer, more controlled way. It accomplishes this by applying the brakes to limit the speed at which your vehicle descends.
Does DAC really matter?
A DAC helps improve audio quality by converting digital audio files into analog sound waves. This process allows our audio systems to create sound with higher quality than ever before.
What does DAC do on a Lexus?
The downhill assist control system is a system that assists the deceleration of the engine brake when you drive down a steep hill. When you are driving down a hill with the four−wheel drive control lever in the “L” position, push the “DAC” switch to limit the vehicle’s acceleration.
