You can drive down a steep incline without using the brakes if your vehicle has the downhill assist control (DAC) system, which is an optional equipment. This is crucial since using your brakes for an extended amount of time, like when descending a mountain, can cause them to overheat and lose some of their efficacy. How to use the DAC system is as follows:
Press the DAC button on the left side of the steering wheel as you are descending a steep gradient.
Now, it’s possible to travel down a hill at a slow pace (around 3 mph) without applying the brakes. To keep your car from speeding up, the system applies engine braking.
While the system is running, pressing the DAC switch will cause it to stop functioning gradually. To let you know that the system is being turned off, the light will flash. When the DAC system is totally off, it will stop flashing.

How can I disable Toyota’s Downhill Assist?
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.
The Toyota DAC button: what is it?
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.
My downward light is on—why?
Hill Descent Management:
- 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.
- 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
Hill Descent Control Operating Conditions:
- driving on a slope that is 10% or more steep.
- The hill decline control switch was activated.
- 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.
- Shift lever for the transmission in forward or reverse.
- lower than 15 mph (24 km/h) vehicle speed.
- The system is ON and limiting vehicle speed if the hill descent control indicator light is ON constantly.
- While the hill descent control system engages the brakes to reduce vehicle speed, the brake lights come on.
- 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.
- The hill descent control system will deactivate if the accelerator or brake pedal is pressed while it is engaged (stop functioning temporarily). 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.
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).
Why is the flashing downhill assist light on?
While the DAC light in the instrument cluster is on steadily, it is engaged; when it blinks, the system is attempting to engage or disengage. I imagine that if the DAC button was depressed and you were driving regularly without realizing it, the light would flash indefinitely because you had to be in L or R and moving at less than 25 mph for it to engage. Sounds like exactly what Karrock encountered; let’s hope it was simply a DAC button bump and not a more significant issue.
Does the Highlander handle snow well?
The 2020 Toyota Highlander is a brand-new vehicle for this model year. It is based on the TNGA modular design used by the business and boasts improvements in rigidity, weight reduction, and interior space over its predecessor. Toyota’s 295hp 3.5L V-6 with D-4S direct and port injectors is the only engine available for the new Highlander, and it is coupled only to an eight-speed automatic transmission. All-wheel drive is an alternative to the front-wheel drive that is the default.
In order to prevent wheelspin when one of the rear wheels has grip and the other doesn’t, the Highlander’s all-wheel-drive system on L, LE, and XLE versions uses a driveline disconnect and an open rear differential. The torque-vectoring rear differential on the top-of-the-line 2020 Toyota Highlander Platinum, on the other hand, has clutch packs that actively distribute power to the right and left rear tires based on how much traction they have. Toyota claims that the rear axle can receive up to 50% of the engine’s torque, which can then, if necessary, be distributed up to 100% right or left.
The Highlander Platinum handled the low-speed snowcross Toyota set up for us with great assurance. The family SUV had enough of front-end shove when slicing through corners with all traction aids engaged and the drive selector in Snow mode, but slowing down to a more sensible speed kept us on the course without incident.
We were able to drift the Highlander like a rally star after disconnecting all of the electronic nannies, which was unexpected. In these circumstances, stepping on the gas showed a very sluggish throttle, but once the Highlander was moving, drifting lazily through the curves was a breeze. The larger wheelbase and heavier, basic V-6 of the Highlander may have contributed to our finding that it was simpler to operate in this way than the smaller, more aggressive Toyota RAV4 TRD Off-Road.
Unambitious all-season tires on the three-row crossover should have been a liability.
But in these conditions, the 2020 Toyota Highlander Platinum proved steady and even enjoyable to drive. Honestly, if you frequently drive in temps below 45 degrees, invest in winter tires. We were somewhat aback by the fact that we could genuinely tell when the clever rear differential was shifting power, demonstrating that it is more than simply a gimmick and has an impact on the dynamics of the vehicle.
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.”
How can I disable the Hill Descent Control feature?
The slope descending aspect is liked by some people and disliked by others. The controls are simple to use in either case. The Ford Focus’s hill descent control can be disabled as follows:
- The hill descent control button should be located above your console’s screen. A small car descending an inclination with a speedometer next to it should be the emblem for it.
- To turn off the hill descent control, press the button.
- Start your vehicle
And presto—the brakes no longer seem stuck! You can always push the button to turn it back on if you change your mind.

How does DAC function?
Simply said, a DAC transforms a digital audio signal into an analog one so that it may be played through headphones or speakers. It’s that easy! Even while the analog headphone jack appears to be a disappearing feature (Editors’ note: a pox on your house, Apple), DAC chips are present in the source component you are listening to, whether it be a laptop, portable music player, or smartphone.
An analog audio signal is produced by your headphones after being converted from a digital audio signal by a DAC.
Similar to headphone amplifiers, standalone DACs were developed as a reaction to subpar audio quality among consumers. The weakest links in the audio chain may be revealed by high-end headphones and speakers, which also show the DACs and output stages of the source components. When consumers started utilizing their PCs as audio sources, this became more clear. The quality of the output is occasionally impacted by the DAC’s inadequate filtering, insufficient shielding, noise introduction, or poorly controlled power supply. There were several audio-related issues that youngsters of the 1990s had to contend with, including lower sample rates and poorly encoded MP3s. Who wants to listen to mediocre music?
Do you require an active speaker DAC?
The audio chain would not be complete without a digital to analog converter (DAC). They enable the use of headphones and speakers to listen to digital music. Although the bulk of music and game sounds we encounter today are digital, are DACs always required for active speakers?
Active speakers don’t require an external DAC to function because every computer, phone, and audio player that can playback sound already has one built in. However, a standalone DAC will typically perform considerably better if you truly appreciate superb audio and desire the best listening experience.
The remainder of this post will go into great detail on a few issues relevant to this inquiry, including the reasons you might need a DAC even though your device already has one built-in, a brief overview of your DAC alternatives, and a few DAC products we favor.
