What Is Adaptive Cruise Control?

• Smarter Cruise Control: Automatically maintains a set speed and adjusts to keep a safe distance from the vehicle ahead using lasers, radar, and/or cameras.
• Traffic Handling: Many systems can bring the car to a full stop in traffic and resume when it moves again. However, some systems require driver input to restart.
• Stress Relief: Reduces tension during long drives or in stop-and-go traffic, as noted by surveyed car owners.

How ACC Works

Activation:
- Use buttons on the steering wheel, often marked with a car and speedometer icon.
- Adjust gap distance using a button showing a car with horizontal bars.

Traffic Response:
- Slows or stops for slower vehicles ahead.
- Resumes preset speed when traffic clears or accelerates as traffic moves.
- Some systems only operate above 20 mph, while others work at low speeds in “traffic jam” or “stop-and-go” scenarios.

Key Features to Look For

Stop-and-Go Capability:
- Not all systems can handle stop-and-go traffic; check for these terms in the system name.
- Some systems shut off at low speeds, requiring driver action to avoid potential hazards.

Responsive Braking:
- Better systems react promptly to merging traffic or cars cutting in.
- Others may brake too late, necessitating driver intervention.

Speed Range:
- Review automaker details to understand speed limitations during your test drive.

Tips for Safe Use

• Stay Alert:
• ACC is a convenience tool, not a replacement for driver vigilance.

• Always monitor traffic and be prepared to take control.

• Plan for Limitations:

• Be aware that ACC systems may struggle to detect vehicles when approaching at high speeds.

Survey Insights

• High Satisfaction:
• Most drivers find ACC reduces stress and fatigue, especially during long drives.

• Older drivers report higher satisfaction with ACC systems.

• Customization:

• Gap distances and speed adjustments are commonly customizable for comfort and safety.

Pro Tips for Buying ACC-Equipped Cars

Test Drive ACC:
- Evaluate responsiveness and stopping ability during a test drive.

Understand Features:
- Read manufacturer details to know speed ranges and whether full-stop capabilities are included.

Check for Safety Upgrades:
- Look for integration with other safety systems like lane-keeping assist or forward collision warnings.

Takeaway: Adaptive Cruise Control enhances convenience and reduces stress but requires an engaged driver for safe operation. Research and test systems to ensure they meet your needs!
