Mercedes Benz GLC Blind Spot Assist: A Comprehensive Guide

1. Understanding Mercedes Benz GLC Blind Spot Assist

Blind spot assist is an advanced driver-assistance system (ADAS) that utilizes sensors to monitor the areas beside and behind your vehicle, which are often difficult to see using traditional mirrors. The Mercedes-Benz GLC blind spot monitoring system is designed to alert the driver to the presence of other vehicles in these blind spots, thereby reducing the risk of lane-change accidents.

1.1. How Blind Spot Assist Works

The blind spot assist system in your Mercedes-Benz GLC employs radar sensors, typically located in the rear bumper, to detect vehicles in the adjacent lanes. When a vehicle enters your blind spot, the system provides a visual warning, usually in the form of an illuminated icon in the side mirror. If the driver activates the turn signal indicating a lane change in the direction of the detected vehicle, the system may provide an audible warning as well.

1.2. Components of the System

The Mercedes-Benz GLC blind spot assist system consists of several key components:

• Radar Sensors: These sensors emit radar waves to detect the presence and distance of vehicles in the blind spot areas.
• Control Unit: This unit processes the data from the radar sensors and determines whether a warning is necessary.
• Visual Warning Indicators: Typically located in the side mirrors, these indicators illuminate to alert the driver to the presence of a vehicle in the blind spot.
• Audible Warning System: Some systems also include an audible warning that sounds when the driver activates the turn signal towards an occupied blind spot.

1.3. Benefits of Blind Spot Assist

• Enhanced Safety: Reduces the risk of accidents by alerting drivers to vehicles in their blind spots.
• Increased Awareness: Provides drivers with a better understanding of their surroundings.
• Reduced Stress: Makes lane changes easier and less stressful, especially in heavy traffic.
• Improved Confidence: Increases driver confidence, especially for those who are new to driving or uncomfortable with lane changes.
• Preventative measures: Blind spot assist acts as a preventative safety measure, reducing the likelihood of collisions.

2. Key Features of Mercedes Benz GLC Blind Spot Assist

The Mercedes-Benz GLC blind spot assist system comes with a range of features designed to enhance safety and convenience. Here’s a closer look at some of the key features:

2.1. Active Blind Spot Assist

Active blind spot assist is an enhanced version of the standard system that can intervene to prevent a collision. If the driver ignores the warnings and continues to move towards the occupied lane, the system can apply selective braking to gently steer the vehicle back into its original lane.

2.2. Exit Warning Assist

Exit warning assist is a feature that alerts occupants exiting the vehicle to the presence of approaching vehicles or cyclists. This is particularly useful in urban environments where cyclists and other vehicles may be approaching quickly. When a person inside the car tries to open the door, a visual and audible warning will sound if there is an oncoming obstacle. This can help prevent accidents, especially for vehicles that are parallel parked alongside a road.

2.3. Blind Spot Monitoring Range

The blind spot monitoring range typically extends approximately 10 to 16 feet (3 to 5 meters) from the side of the vehicle and about 16 feet (5 meters) behind the rear bumper. This range can vary depending on the specific system and vehicle configuration.

2.4. Visual and Audible Alerts

The system provides both visual and audible alerts to ensure the driver is aware of potential hazards. Visual alerts are typically displayed in the side mirrors, while audible alerts may sound when the driver activates the turn signal.

3. Activating and Deactivating Blind Spot Assist

Activating and deactivating the blind spot assist system in your Mercedes-Benz GLC is a straightforward process. Here’s how you can do it:

11. Understanding Diagnostic Trouble Codes (DTCs)

Diagnostic Trouble Codes (DTCs) are codes that a vehicle’s onboard computer stores when it detects a problem with a system or component. When it comes to the Mercedes-Benz GLC Blind Spot Assist, understanding these codes is essential for effective troubleshooting and repair.

11.1. How to Retrieve DTCs

To retrieve DTCs, you’ll need an OBD-II scanner. This tool connects to your vehicle’s OBD-II port, usually located under the dashboard. Once connected, the scanner can read any stored codes. High-end diagnostic tools like the Mercedes-Benz XENTRY Diagnostics, Autel MaxiSYS MS906BT, or Launch X431 V+ offer more advanced features, such as live data streaming and system tests, which can help pinpoint the exact issue.

11.2. Common DTCs Related to Blind Spot Assist

Here are some common DTCs that might appear when there’s an issue with the Blind Spot Assist system:

• C156700 – Radar sensor 1 has a malfunction: This indicates an issue with the radar sensor’s functionality.
• C156800 – Radar sensor 2 has a malfunction: Similar to the above, but for the second radar sensor.
• C1A600 – The supply voltage of the radar sensors is too low: This suggests a power supply problem affecting the sensors.
• C1A610 – The supply voltage of the radar sensors is too high: Indicates an overvoltage issue.
• U118800 – Fault in communication with the blind spot assist system: This points to communication errors between the system’s components.

11.3. Interpreting DTCs

Each DTC consists of a five-character alphanumeric code. The first character indicates the system (e.g., “C” for chassis), followed by numbers that specify the area of the fault. To accurately interpret a DTC, refer to the vehicle’s service manual or a reliable online database. Here’s a basic breakdown:

• First Character:
  • B: Body
  • C: Chassis
  • P: Powertrain
  • U: Network
• Second Character:
  • 0: Standardized code
  • 1, 2, 3: Manufacturer-specific code
• Third, Fourth, and Fifth Characters: Specify the specific fault

For example, a code like “C156700” tells you it’s a chassis-related issue (C), it’s manufacturer-specific (1), and further specifies a malfunction with radar sensor 1 (567).

11.4. Clearing DTCs

After repairing the issue, it’s important to clear the DTCs. Most OBD-II scanners can clear codes, but be cautious. Only clear codes after you’ve confirmed the problem is resolved. Clearing codes without fixing the underlying issue will only result in the code reappearing.

11.5. When to Seek Professional Help

If you’re not comfortable diagnosing or repairing the issue yourself, it’s best to seek professional help. Complex issues, especially those involving advanced systems like Blind Spot Assist, may require specialized tools and expertise.
