Many modern vehicles come equipped with safety driver-assist sensors. The majority of them focus on lane-keeping assistance or blind-spot monitoring, but the 2020 Toyota 4Runner receives even more. The 4Runner can avoid rolling backward downhill when the driver presses the pedal while climbing by using Hill Start Assist Control (HAC). When driving down a steep or slick slope, Downhill Assist Control (DAC) sort of handles the opposite scenario by selectively applying braking force to control the vehicle’s speed.

Why is there a DAC button?
Downhill Assist Control (DAC) is a feature on the new Toyota Hilux* that makes difficult descents on uneven surfaces simple. Downhill Assist Control maintains speed and control whether you are moving forward or backward.
When the Hilux is in 4WD mode, the Downhill Assist Control is active.
Observe this post to discover how to activate 4WD.
Press the switch on the center console to turn on the downhill assist control. When the system is ready, the DAC light will illuminate.
Without the driver’s involvement, the Downhill Assist Control stops individual wheels as you descend the hill to maintain control and a safe rate of descent. This implies that you don’t even need to depress the brake or throttle pedals—Hilux takes care of the laborious tasks.

What does Toyota DAC stand for?
When beginning on steep hills or slick terrain, there may be unanticipated situations for the driver when the vehicles may skid. By regulating the braking fluid pressure as the driver shifts their foot from the brake to the accelerator on such a high gradient, HAC reduces vehicle roll-back.
Additionally, DAC keeps the speed of the vehicle at 5 km/h to help maintain vehicle stability when descending steep hills or slick surfaces.
On incline climbs, the HAC system increases control and keeps individual wheels from locking.
On steep or slippery slopes, the DAC system enhances directional control during descent.
Has the 4Runner TRD off-road got downhill assistance?
The 2022 Toyota 4Runner has a vast number of off-road options that will enable you to navigate even the toughest terrain and delivers sophisticated capabilities in several of its trim levels. An X-REAS suspension system, 20-inch alloy wheels, off-road tires, an electronically controlled locking rear differential, Crawl Control (CRAWL), a Kinetic Dynamic Suspension System (KDSS), and Multi-Terrain Select (MTS) with four different terrain modes are a few of the off-road features offered in the 2022 Toyota 4Runner. These features allow you to dial in and optimize the traction you need for the particular surface you’re driving on. Hill Start Assist (HAC), Downhill Assist Control (DAC), Active Traction Control (A-TRAC), and a Torsen limited-slip differential with locking function are some of the 2022 Toyota 4Runner’s additional off-road capabilities.
How can I stop DAC?
How to disable the Downhill Assist feature in a Toyota
- By depressing the “DAC switch,” the downhill aid control system will be activated.
- As soon as the system is turned on, the downhill assist control system indication will illuminate.
- To turn the system off, merely push the switch once more.
My downhill assist light is on, why?
Hill Descent Management:
- only works when the 4H or 4LO switch is flipped on.
- aids in maintaining vehicle speed when traveling at less than 15 mph (24 km/h) on descents with a slope of roughly 10% or greater.
- when engine braking is insufficient to control vehicle speed
- The driver can focus on steering while decreasing the load of brake and accelerator operation by applying the brakes to control the vehicle’s speed.
Hill Descent Control Operating Conditions:
- activated 4H or 4LO.
- The hill descent control system is on, but not engaged and not reducing vehicle speed if the hill descent control indicator light is blinking.
- The hill decline control switch was activated.
- Shift lever for the transmission in forward or reverse.
- The system is ON and limiting vehicle speed if the hill descent control indicator light is ON constantly.
- driving on a slope that is 10% or more steep.
- lower than 15 mph (24 km/h) vehicle speed.
- While the hill descent control system engages the brakes to reduce vehicle speed, the brake lights come on.
- The hill descent control system will deactivate if the accelerator or brake pedal is pressed while it is engaged. The hill descent control system re-engages and resumes operation as soon as the accelerator or brake pedal is released, provided that the operational criteria are met.
- If the switch is turned on and any of the working conditions are not met, or if the system disengages for any reason, the hill descent control indicator light will blink.
- Push the switch all the way to the OFF position to disable the hill descent control mechanism.
Note:
- When the hill descent control works, sounds may be heard or very minor vibrations may be felt through the brake pedal (similar to ABS action). That is typical.
- The hill descent control switch should be turned ON and the shift lever should be in M1 (1st) for engine braking for optimal performance when descending steep downhill grades.
- For hill descent control to be activated and control vehicle speed, the speed of the vehicle must not exceed 15 mph (24 km/h).
WHAT IT DOES
This function assists in maintaining a predetermined safe speed for your car when it is moving downhill or across severely uneven terrain. You can now concentrate more on looking for any dangers along the downhill path.
THE TECHNOLOGY BEHIND IT
This function prevents you from exceeding a particular speed while moving downhill or over uneven terrain by integrating with the existing braking systems of your car. This feature will further apply the brakes if your automobile starts to accelerate past a safe downhill pace.
WHAT YOU NEED TO DO
The hill descent assist switch must first be turned on, and it is usually located someplace on the dashboard close to the traction control button. Some versions can be turned on using the dial on your terrain management control or your multifunction display.
Reduce your speed to below the level required for your feature to activate as you are about to enter a decline. The hill descent assist will further apply the brakes if necessary to prevent your car from descending at an unsafe speed.
TIPS FOR USING
- When going downhill, keep an eye out for any hazards and be ready to steer around them if required.
- If your version of hill descent assist doesn’t automatically turn on your brake lights, make sure to keep lightly applying the brake to let traffic behind you know that you might be progressively slowing down.
- When employing hill descent aid, avoid attempting to descend hills or other drops that are steeper than you would otherwise try to traverse.
A DAC switch: what is it?
When driving downhill on a steep slope, the DAC helps to curb excessive speed. The system will function if the four-wheel drive control switch is in the L4 position and the vehicle is moving at a speed of less than 15 mph (25 km/h). system performance. Turn on the “DAC switch.”
