The engine also adjusts power to avoid sudden acceleration. DAC works without the driver touching the brake or gas pedals. It lets you focus on steering while the system controls speed.
When To Use Dac
Use DAC on steep downhill roads, especially on loose dirt or gravel. It helps maintain control on slippery or uneven terrain. Avoid using DAC on flat or smooth roads. The system is designed for low-speed descents, not for regular driving.
Activate the DAC button before starting the descent. Keep your hands on the wheel and let the system manage your speed. This reduces the risk of losing control and improves safety.
Benefits For Off-road Driving
The DAC button in the Toyota 4Runner offers key benefits for off-road driving. It helps drivers handle steep and rough terrain with ease. This feature improves vehicle control and safety. It makes tough descents less risky and more manageable.

Common Myths About Dac
The DAC button in a Toyota 4Runner often causes confusion among drivers. Many myths surround its use and function. Clearing these myths helps drivers use DAC correctly and safely. Understanding what DAC truly does improves your off-road experience.
Some people think DAC works like a regular cruise control. Others believe it can replace careful driving on steep slopes. These ideas are not accurate and can lead to unsafe driving habits. Knowing the facts about DAC keeps you safer on rough roads.
Misconceptions Cleared
DAC stands for Downhill Assist Control. It helps control your speed on steep declines. It does not replace your brakes or require less attention. DAC works by automatically applying brakes to keep a slow, steady speed. It is not useful on flat or slippery surfaces. Using DAC on dry pavement can cause damage. It is only meant for steep and rough downhill areas. Some think DAC can speed up the vehicle. It cannot. It only helps slow the vehicle down.
Proper Usage Tips
Activate DAC before starting the descent. Keep your foot off the brake pedal while DAC is active. Steer carefully and watch the road ahead. Do not rely only on DAC for safety. Use regular brakes if you need to stop quickly. Turn off DAC once the slope ends. Avoid using DAC on sharp turns or loose gravel. Follow the owner’s manual for detailed instructions.
