Understanding Honda Adaptive Cruise Control (ACC): More Than Just Cruise Control

Before we dive into the “how-to,” let’s clarify what Honda Adaptive Cruise Control actually is. Think of it as an intelligent evolution of traditional cruise control. While standard cruise control maintains a fixed speed, ACC goes a significant step further.

Your Honda’s ACC system uses radar and/or camera sensors, typically located in the front grille or behind the rearview mirror, to detect vehicles in front of you. When enabled, it doesn’t just hold your speed; it actively adjusts it to maintain a pre-selected following distance from the car ahead. If traffic slows, your Honda slows down, and if traffic speeds up, your Honda accelerates back to your set speed – all automatically.

The benefits of how to use Honda Adaptive Cruise Control are clear: reduced driver fatigue, enhanced safety by helping maintain safe following distances, and a generally more relaxed driving experience, especially in stop-and-go highway traffic. It’s a powerful tool that contributes to safer, more comfortable journeys.

How ACC Differs from Traditional Cruise Control

Traditional Cruise Control: Sets a fixed speed. If a car ahead slows down, you must manually brake and then reset your speed.
Adaptive Cruise Control: Sets a desired speed and a following distance. Automatically adjusts speed to maintain that distance, including braking and accelerating.

Step-by-Step Guide: How to Use Honda Adaptive Cruise Control

Ready to put your Honda’s intelligent system to work? Here’s a detailed how to use Honda Adaptive Cruise Control guide to get you started. Remember, while the exact button layout might vary slightly by model year, the core functions remain consistent.

- Most Honda models have ACC controls on the right side of the steering wheel.
- Look for a button labeled “MAIN” or a cruise control icon (often a speedometer needle). This activates the system.
Activate the System:
- Press the “MAIN” button. You’ll see an indicator light on your dashboard, usually green, showing that ACC is ready.
- In some models, this also activates the Lane Keeping Assist System (LKAS) if equipped.
Set Your Desired Speed:
- Once you’re at your desired cruising speed (typically above 25-30 mph for most systems), press the “SET -” button.
- The set speed will appear on your multi-information display.
- Your vehicle will now maintain this speed, unless it detects a vehicle ahead.
Adjust Following Distance:
- Look for a button with car-like icons and lines between them (often resembling three bars). This is your distance control button.
- Pressing this button will cycle through different following distances (e.g., long, medium, short).
- The selected distance will display on your dashboard. Start with the longest distance until you get comfortable.
Engage and Disengage:
- To increase your set speed, press “RES/+” (Resume/Plus).
- To decrease your set speed, press “SET -“.
- To temporarily cancel ACC (e.g., for an exit), press the “CANCEL” button or lightly tap the brake pedal.
- To fully turn off the system, press the “MAIN” button again.

It’s that simple! Practice in light traffic on a familiar highway to build your confidence.

Mastering the Settings: Distance and Speed Adjustments

Getting comfortable with your Honda’s ACC means understanding how to fine-tune its behavior on the fly. Adjusting your following distance and set speed is crucial for different driving conditions.

Choosing the Right Following Distance

Your Honda ACC typically offers three or four distance settings. These settings determine how much space your vehicle will maintain between itself and the car in front.

Longest Distance: Ideal for high speeds, wet conditions, or when you prefer a larger buffer. This is generally the safest starting point for new users.
Medium Distance: Suitable for moderate highway traffic and drier conditions.
Shortest Distance: Useful in denser traffic where you need to keep up with the flow, but requires more vigilance. Use with caution.

To change the distance, simply press the distance control button on your steering wheel. Observe the indicator on your dashboard to confirm your selection.

Adjusting Your Set Speed

Once ACC is active, you can modify your cruising speed without canceling the system:

Increase Speed: Press the “RES/+” button. Each press typically increases the speed by 1 mph (or 5 mph if you press and hold).
Decrease Speed: Press the “SET -” button. Each press typically decreases the speed by 1 mph (or 5 mph if you press and hold).

Always be aware of the posted speed limits and adjust your speed accordingly. ACC is a convenience feature, not a license to disregard traffic laws.

Advanced Tips for Optimal Honda ACC Use

Beyond the basics, there are several how to use Honda Adaptive Cruise Control tips that can enhance your experience and ensure you’re using the system effectively and safely.

Anticipate Traffic: While ACC is smart, it’s not psychic. If you see brake lights far ahead or anticipate a lane change from a vehicle in front, be ready to manually intervene by tapping the brake.
Merging and Exiting: When merging onto a highway, accelerate manually to your desired speed before engaging ACC. When exiting, it’s often best to cancel ACC and take full manual control.
Lane Changes: When you signal and move into an open lane, your ACC will accelerate back to your set speed. If you move behind a slower vehicle, it will adjust accordingly.
Rain and Snow: ACC sensors can be affected by heavy rain, snow, or fog. Your vehicle may display a message indicating “ACC Unavailable.” In such conditions, always drive manually and reduce speed.
Sun Glare: Direct, low-angle sun glare can sometimes temporarily impair the camera sensor. Be prepared for the system to temporarily disengage or warn you.
Keep Sensors Clean: The radar unit (often behind the Honda “H” badge) and the camera (behind the rearview mirror) need to be clean for ACC to function correctly. Regularly wipe them free of dirt, ice, or bugs. This is part of the how to use Honda Adaptive Cruise Control care guide.

These how to use Honda Adaptive Cruise Control best practices will help you get the most out of your system while prioritizing safety.

When to Use It (and When Not To): Safety First

While Honda ACC is a fantastic feature, it’s crucial to understand its limitations. It’s a driver-assist system, not an autonomous driving system. You, the driver, are always responsible for operating the vehicle safely.

Ideal Scenarios for ACC

Highway Driving: Long stretches of highway with consistent traffic flow are where ACC shines, reducing fatigue.
Light to Moderate Traffic: It can handle stop-and-go traffic well, but requires driver vigilance.
Familiar Routes: Using it on routes you know well can help you anticipate when manual intervention might be needed.

When NOT to Rely on ACC

There are specific situations where ACC should be disengaged or not used:

Heavy Rain, Snow, or Fog: Reduced visibility and sensor performance make manual control essential.
Icy or Slippery Roads: ACC cannot account for traction loss. Manual braking and acceleration are critical.
Winding Roads or Sharp Curves: The system may not detect vehicles around sharp bends, and it’s not designed for aggressive cornering.
Off-Road Driving: Absolutely not. ACC is designed for paved roads. Uneven terrain, steep inclines/declines, and unpredictable surfaces are entirely outside its operational parameters. As FatBoysOffroad enthusiasts, we know that off-road driving demands full manual control and driver skill.
Approaching Toll Booths or Complex Intersections: Take manual control to ensure smooth and safe navigation.
Emergency Braking: While ACC can brake, it’s not designed for emergency stops. Always be ready to apply full brake pressure yourself.

Always keep your hands on the wheel and your eyes on the road. Be prepared to take over at any moment. Your safety and the safety of others depend on it.

Common Questions and Troubleshooting for Honda Adaptive Cruise Control
