The advanced technology and advanced safety features in the Mercedes-Benz CLA are part of what make it such an attractive car. Starting at just over $30,000, buyers can get behind the wheel of a well-equipped luxury car at a surprisingly affordable price. That price tag also leaves room for many buyers to add useful features and packages, like Blind Spot Assist.
Blind Spot Assist uses radar technology to sense when vehicles enter the driver’s blind spot. When activated, the driver will see a red icon in the side mirror when a vehicle enters the driver’s blind spot. If the driver initiates the turn signal while a vehicle is in a blind spot, an audible alert will sound as well.
Like any piece of technology, Blind Spot Assist on the Mercedes-Benz CLA is not always 100 percent reliable and is not a replacement for safe driving habits. Although it has proven to be a useful aid for drivers time and time again, nothing can replace a manual blind spot check, so it’s important anyone with Blind Spot Assist still uses their mirrors and turns to check blind spots when necessary.
Mercedes-Benz CLA Blind Spot Assist Issues & Solutions
There are a few issues drivers have had with Blind Spot Assist in the Mercedes-Benz CLA, including:
- Not detecting vehicles in blind spots
- Detecting vehicles two lanes over
- Alerting drivers when they exit off the interstate
- Detecting barriers and other objects on the road
We’ll provide a few possible solutions to these problems below, which we hope will apply to any other issues drivers might have with their Blind Spot Assist.
Please note, if any issues persist or the they are occurring frequently, there may be a problem with the system that should be looked at. Schedule a service appointment so we can get your system functioning properly.
The fact is, Blind Spot Assist is a great asset and one that has helped a lot of CLA owners avoid a collision. While a few owners have reported issues and there are occasionally necessary repairs, the great majority of CLA owners have no problems with their Blind Spot Assist throughout the course of ownership.
Not Detecting Vehicles in Blind Spots
Remember, Blind Spot Assist only begins working when you are traveling over 20 mph, so if you’re in a parking lot or in stop-and-go traffic, you probably won’t get the normal visual alert. If you notice your Blind Spot Assist isn’t detecting vehicles at normal driving speeds, go to the necessary menu options to make sure it’s on. If it is, sometimes a quick restart will do the trick. Deactivate the system for a few minutes and turn it back on.
It could also mean the sensors are dirty, preventing the radar from detecting other vehicles. Wipe the sensors clean or visit a nearby Mercedes-Benz dealership to have them properly cleaned.
Lastly, Blind Spot Assist may not recognize small vehicles or motorcycles, so it’s extremely important you are always checking your blind spots and not solely relying on the technology.
Detecting Vehicles Two Lanes Over
This is not necessarily a problem as much as it is a function of the radar. This will more often occur with larger vehicles that are two lanes over, and although it may not be completely necessary, it should prompt you to check your blind spots and be more aware of your surroundings. Even when there is a lane separating you and a semi, you’re both just a lane change away from a potential collision.
Alerting Drivers While Exiting the Interstate
Although you may have no intention of returning to the highway, Blind Spot Assist will still provide a visual indicator when a vehicle is in a blind spot. The radar doesn’t send alerts based on your driving manuevers, only the location of other vehicles, so this is pretty normal.
Detecting Barriers and Other Objects
Every now and then, Blind Spot Assist may alert you when there is no vehicles anywhere close. In this case, it’s likely picking up other objects, and while that may cause you to check your blind spots a little more often, that’s not necessarily a bad thing!
