Understanding the Forward Emergency Braking System
The Forward Emergency Braking system in the Nissan Qashqai is part of the vehicle's Intelligent Safety Shield technologies. It uses radar sensors to detect potential collisions and can automatically apply the brakes if the driver doesn't respond in time. While this system can be a lifesaver, it's not without its quirks and potential issues.
How FEB Works
The FEB system relies on a radar sensor located behind the Nissan emblem on the front grille. This sensor constantly monitors the road ahead, measuring the distance and relative speed of vehicles in front of the Qashqai. When it detects a potential collision, it follows a three-step process:
- Visual and audible warnings to alert the driver
- Partial application of brakes if the driver doesn't respond
- Full emergency braking if a collision is imminent
Common FEB Warning Light Issues
Many Qashqai owners have reported problems with the FEB warning light, which can be both frustrating and concerning. Let's explore the most common issues and their potential causes.
1. Persistent Warning Light
One of the most frequently reported problems is a persistent FEB warning light on the dashboard. This issue is often accompanied by a message stating "Front radar unavailable due to obstruction."
"My Forward Emergency Braking system warning light comes on (this means the sensor is not working and the emergency warning is not working; further you cannot use cruise control when the light is on). This has been a problem from the beginning of owning the car."[23]
This persistent warning can be caused by several factors:
- Dirty or obstructed sensor: The radar sensor may be covered by dirt, snow, or other debris.
- Sensor misalignment: The sensor may have become misaligned due to a minor collision or improper installation after repairs.
- Software glitch: In some cases, a software issue may be causing the system to falsely detect an obstruction.
2. Intermittent Warning Light
Some drivers report that the FEB warning light blinks intermittently or turns on and off seemingly at random. This can be particularly disconcerting as it may indicate an unreliable system.
"Emergency braking keeps sending me alerts when there is nothing in front of me. I'm getting messages that the system is disabled because of an obstruction. This happens a lot of times when it's raining out."[23]
Causes of intermittent warnings may include:
- Environmental factors: Heavy rain, snow, or fog can interfere with the radar sensor's function.
- Electrical issues: Loose connections or wiring problems may cause the system to malfunction sporadically.
- Faulty radar module: The radar module itself may be defective, leading to inconsistent performance.
3. False Activations
Perhaps the most alarming issue is when the FEB system activates unnecessarily, applying the brakes when there is no apparent danger. This can be dangerous, especially in high-speed situations.
"We purchased a 2018 Nissan Rogue in June. Today, we drove 75 miles and the emergency braking activated 4 times for no reason, once on the interstate, once on the off ramp, and twice on the highway. There were no railroad tracks or other obstacles."[23]
Possible reasons for false activations include:
- Oversensitive radar: The system may be too sensitive, detecting non-existent obstacles.
- Software bugs: Faulty programming could cause the system to misinterpret sensor data.
- Electromagnetic interference: In rare cases, external electromagnetic fields might interfere with the radar's function.
Troubleshooting FEB Warning Light Issues
If you're experiencing problems with your Qashqai's FEB warning light, there are several steps you can take to troubleshoot the issue:
1. Clean the Sensor Area
The first and simplest step is to ensure that the radar sensor is clean and unobstructed.
- Locate the sensor behind the Nissan emblem on the front grille.
- Gently clean the area with a soft, damp cloth.
- Remove any debris, snow, or ice that may be blocking the sensor.
Positive action: Regular cleaning can prevent many FEB system issues and ensure optimal performance.
2. Check for Environmental Factors
Be aware that certain weather conditions can affect the FEB system's performance:
- Heavy rain or snow can temporarily disable the system.
- Extreme temperatures (hot or cold) may impact sensor function.
- Fog or mist can interfere with the radar's ability to detect obstacles.
In these cases, the system may disable itself as a precaution. Once conditions improve, the system should return to normal operation.
3. Restart the Vehicle
Sometimes, a simple restart can resolve electronic glitches:
- Turn off the engine and wait for at least 30 seconds.
- Restart the vehicle and check if the warning light has cleared.
Information: This method can often clear temporary software issues that may be causing the warning light to illuminate.
4. Check the Vehicle Settings
Ensure that the FEB system is properly enabled in your vehicle's settings:
- Navigate to the vehicle settings menu on your dashboard display.
- Look for "Driver Assistance" or "Safety Features" options.
- Verify that the Forward Emergency Braking system is turned on.
If the system is off, enable it and see if this resolves the warning light issue.
5. Consult Your Owner's Manual
Your Qashqai's owner's manual contains valuable information about the FEB system and its warning lights. Consult it for model-specific troubleshooting steps and explanations of warning messages.
When to Seek Professional Help
While some FEB issues can be resolved through simple troubleshooting, others require professional attention. Consider visiting a Nissan dealer or qualified mechanic if:
