1. Understanding Adaptive Highbeam Assist and Adaptive Highbeam Assist Plus

1.1. What is Adaptive Highbeam Assist?

Adaptive Highbeam Assist is an advanced lighting system designed to automatically switch between high beams and low beams based on the presence of other vehicles. The system uses a camera, typically mounted on the windshield, to detect headlights and taillights of oncoming and preceding vehicles. According to Mercedes-Benz, this system enhances visibility by ensuring the high beams are used whenever possible, while preventing glare for other drivers. The primary goal is to provide the best possible lighting without manually adjusting the high beams.

1.2. What is Adaptive Highbeam Assist Plus?

Adaptive Highbeam Assist Plus builds on the capabilities of the standard Adaptive Highbeam Assist system by offering more sophisticated control over the high beams. Instead of simply switching between on and off, Adaptive Highbeam Assist Plus can partially dim the high beams to avoid dazzling other drivers while still providing maximum illumination in other areas. This is achieved through individually controlled LEDs that can adjust the light distribution dynamically. Mercedes-Benz states that this system can adapt to various driving situations, providing a more nuanced and effective lighting solution.

1.3. Key Differences Between the Two Systems

The main difference between Adaptive Highbeam Assist and Adaptive Highbeam Assist Plus lies in their level of control and adaptability. Adaptive Highbeam Assist is a binary system, switching high beams on or off. Adaptive Highbeam Assist Plus, however, offers a more granular approach by dynamically adjusting the intensity and direction of the high beams. This allows for continuous high beam operation in many scenarios, maximizing visibility without causing glare.

Feature	Adaptive Highbeam Assist	Adaptive Highbeam Assist Plus
Operation	On/Off Switching	Dynamic Adjustment
Light Control	Basic	Advanced
LED Control	Limited	Individual LED Control
Glare Reduction	Basic Switching	Partial Dimming
Driving Situations	Fewer	More
Visibility Enhancement	Good	Excellent

2. Benefits of Adaptive Highbeam Assist and Adaptive Highbeam Assist Plus

2.1. Enhanced Visibility

Both Adaptive Highbeam Assist and Adaptive Highbeam Assist Plus significantly improve visibility during nighttime driving. By automatically utilizing high beams whenever possible, drivers can see farther and react more quickly to potential hazards. Adaptive Highbeam Assist Plus takes this a step further by shaping the light beam to illuminate the road ahead while minimizing glare for other drivers.

2.2. Increased Safety

Enhanced visibility directly translates to increased safety. Studies have shown that better lighting can reduce the risk of accidents at night. The automatic adjustment of high beams ensures that drivers have optimal vision without the distraction of manually switching between high and low beams. Adaptive Highbeam Assist Plus further enhances safety by providing a more consistent and controlled lighting environment.

2.3. Convenience

The convenience of automatic high beam control cannot be overstated. Drivers no longer need to constantly monitor and adjust their high beams, reducing workload and allowing them to focus on the road. This is particularly useful on long drives or in areas with varying lighting conditions. The Adaptive Highbeam Assist systems make driving less tiring and more enjoyable.

3. Compatibility: Which Mercedes-Benz Models Have This Feature?

Adaptive Highbeam Assist and Adaptive Highbeam Assist Plus are available on a wide range of Mercedes-Benz models. Generally, these features are offered on models starting from the C-Class and above, including the E-Class, S-Class, GLC, GLE, and GLS. However, availability can vary depending on the model year and optional packages.

To determine if your Mercedes-Benz has Adaptive Highbeam Assist or Adaptive Highbeam Assist Plus, consult your vehicle’s owner’s manual or check the vehicle’s specifications. You can also look for the corresponding option code on your vehicle’s build sheet, which can be obtained from a Mercedes-Benz dealer or by using an online VIN decoder.

4. How to Check if Your Mercedes-Benz Has Adaptive Highbeam Assist

1. Check the Owner’s Manual: The owner’s manual provides a detailed description of all the features available in your vehicle. Look for “Adaptive Highbeam Assist” or “Adaptive Highbeam Assist Plus” in the index or lighting section.
2. Examine the Control Stalk: The control stalk, typically located on the left side of the steering column, may have a symbol indicating the Adaptive Highbeam Assist function. This symbol usually looks like a headlight with an “A” inside.
3. Navigate the Vehicle Settings Menu: Many Mercedes-Benz models allow you to enable or disable Adaptive Highbeam Assist through the vehicle settings menu on the infotainment screen. Look for lighting settings or driver assistance features.
4. Visual Inspection: When driving at night, observe whether your high beams automatically adjust based on the presence of other vehicles. If the high beams switch on and off without manual input, it is likely that your vehicle has Adaptive Highbeam Assist. For Adaptive Highbeam Assist Plus, you may notice the high beams partially dimming or shaping around other vehicles.
5. VIN Decoder: Use a VIN (Vehicle Identification Number) decoder online to get a detailed list of your vehicle’s factory-installed options. Enter your VIN on a reputable VIN decoder website and look for Adaptive Highbeam Assist or Adaptive Highbeam Assist Plus in the list of features.
6. Consult a Dealer: If you are unsure, contact your local Mercedes-Benz dealer. They can use your VIN to confirm whether your vehicle is equipped with Adaptive Highbeam Assist or Adaptive Highbeam Assist Plus.
