Mercedes-Benz A-Class ACC activation via OEM options: $150+. Adds Adaptive Cruise Control for safer, less fatiguing highway driving.
Enhance Your Mercedes-Benz A-Class with OEM Options
For Mercedes-Benz A-Class owners who frequently drive on highways, reducing fatigue during long journeys is a top priority. This review focuses on activating the Adaptive Cruise Control (ACC) system for the Mercedes-Benz A220, a popular factory option retrofit that significantly boosts convenience and safety. While many A-Class models sold in Korea come equipped with the necessary radar for ACC, the feature is often deactivated from the factory. Fortunately, activating it is achievable through a straightforward process involving a steering wheel switch replacement and coding.
The Benefits of ACC Activation
Unlike traditional cruise control, which requires constant driver intervention to adjust speed based on traffic, ACC automatically maintains a set distance from the vehicle ahead. This capability dramatically reduces driver fatigue on highways and contributes to safer driving. The process begins with replacing the existing steering wheel switches. For the A220, the left-hand steering wheel switch typically only supports standard cruise control. This is swapped for a dedicated ACC switch set, which includes buttons for adjusting the following distance, allowing for more intuitive operation after activation.
OEM Options Installation Process
- Steering Wheel Switch Replacement: The existing standard cruise control switches on the steering wheel are carefully removed and replaced with a new set designed for ACC functionality.
- Coding and Activation: Following the hardware change, a coding procedure is performed to enable the ACC system within the vehicle's computer.
- Road Test and Calibration: A short road test, approximately 10 minutes, is crucial for the radar sensor to recognize and calibrate to the surrounding environment, ensuring accurate operation.
During a road test, the system demonstrated its effectiveness. With a set speed of 60 km/h, the vehicle automatically adjusted to 43 km/h when the car ahead slowed down, maintaining the preset distance. This seamless integration into traffic flow makes for a much more relaxed and secure driving experience. The cost for this factory upgrade, when the radar is already present, involves only the switch replacement and coding, making it a cost-effective way to add significant value and comfort to your A-Class.
It's important to note that if your A-Class is not equipped with the ACC radar unit from the factory, the cost for parts alone could exceed 2,500-3,000,000 KRW (approximately $2,000-$2,500 USD). However, for Korean-market A-Class models that already have the radar, the activation through switch replacement and coding offers a high degree of satisfaction for a reasonable price. This OEM option is highly recommended for any A-Class owner seeking to enhance both the convenience and safety of their vehicle.
Frequently Asked Questions
Q. How much does OEM option and factory upgrade installation cost for a Mercedes-Benz A-Class?
The OEM options installation for ACC on a Mercedes-Benz A-Class, when the radar is already equipped, typically costs around $150+ USD in Korea. Costs can vary significantly if the radar unit needs to be added, potentially exceeding $2,000 USD.
Q. How long does OEM options installation take on a Mercedes-Benz A-Class?
The installation of OEM options like ACC, including switch replacement, coding, and road testing, usually takes between 1 to 2 hours. Proper maintenance involves ensuring the radar sensor remains unobstructed and recalibrating if any suspension work is done.
Q. Are OEM options worth adding after purchase for a Mercedes-Benz A-Class?
Adding OEM options like ACC is highly recommended for Mercedes-Benz A-Class owners who frequently drive on highways, as it significantly enhances comfort and safety. The value proposition is particularly strong when the necessary hardware is already factory-installed, making the upgrade cost-effective.
Q. How are OEM factory options installed on a Mercedes-Benz A-Class?
OEM factory options such as ACC are typically installed by replacing existing steering wheel switches with ACC-compatible ones. This is followed by a coding process to activate the feature in the car's system, and finally, a road test for sensor calibration.
Q. What is the difference between dealer-installed options and aftermarket upgrades for a Mercedes-Benz A-Class?
Dealer-installed OEM options, like factory ACC, are integrated seamlessly with the vehicle's existing systems and often maintain warranty coverage. Aftermarket upgrades, while sometimes cheaper, may not offer the same level of integration or long-term reliability.
