Are you looking to buy a Volvo car because of its safety systems? That’s an excellent idea! Many Volvo models come with factory-installed advanced driving assistance systems. In fact, all of its recent releases use advanced tools to facilitate drivers in one way or another. Some notable features include adaptive cruise control, automatic emergency braking, and collision avoidance. However, only a few are as effective as the Volvo blind spot sensor.
Volvo has its pre-installed blind spot information system. Also known as BLIS, it provides drivers with a broader view of their surroundings. The fundamental component of this system is the Volvo blind spot sensor. What is it? How does it help drivers? Let’s find out in this detailed guide!

Overview of Volvo Blind Spot Sensor
The Volvo blind spot sensor is an advanced driving assistance system. It uses radar sensors to detect oncoming vehicles in the Volvo’s blind spots. The well-known manufacturer integrates this system in many of its cars and SUVs. That includes:
- Volvo XC40
- Volvo XC60
- Volvo XC90
- Volvo S60
- Volvo S90
- Volvo V90
- Volvo V60

Generally, Volvo offers its blind spot sensor in three different trim levels. The Basic package has it as an optional add-on, while the Mid Trim features it as a mandatory addition. Lastly, the High Trim offers a blind spot sensor as a standard feature.
Usually, the Volvo blind spot sensor is part of the manufacturer’s entire blind spot information system. The primary purpose of this system is to monitor your no-zones. These are areas invisible to the side-view mirrors, making them challenging to navigate through. This system makes it easy by providing real-time updates about your blind spots, encouraging you to make better decisions.
Volvo Blind Spot Sensor Compatibility with Other Safety Features
Did you know that the Volvo blind spot sensor works efficiently with other safety features? Usually, a Volvo release integrates multiple driving assistance systems. The blind spot information system (BLIS) works collaboratively with these systems. Let’s look at some examples:

City Safety
City safety is one of the most popular Volvo safety systems. It helps detect what the blind spot sensor fails to do. That includes the likes of smaller vehicles, like bicycles and longboards. Additionally, it also detects pedestrians to avoid road crashes and injuries.
What’s more is that city safety can also monitor the stationary vehicles in your Volvo’s proximity. That means you can navigate through parked vehicles, guard rails, or poles, without worrying about collisions. However, the best part about the city safety system is its ability to take action automatically. If it detects an imminent threat, it can hit the brakes, protecting you from collisions.
Rear Collision Warning
The rear collision warning is an additional safety system in Volvo sedans, SUVs, and wagons. It complements the blind spot information system by increasing its protection. That is by keeping an extra pair of eyes on your vehicle’s rear area.
Remember that wagons and SUVs are comparatively bigger than an ordinary car. Thus, their rear blind spot is more dangerous. The rear collision warning prevents back collisions by providing drivers with real-time alerts. If a vehicle gets too close to your rear bumper, the system triggers a notification. Hence, the driver can know what’s going on in their vehicle’s back area.
Traffic Sign Recognition
Volvo is pretty famous for this traffic sign recognition system. This advanced driving assistance tool reads the traffic signs and displays them on your Volvo’s infotainment system. Although it might not seem much, it can help in different scenarios.
For instance, the driver has missed an important traffic sign due to distraction. The display on the infotainment system can help the driver by providing a remainder. This way, they can comply with the traffic sign even if they have missed it.
4 Key Features of Volvo Blind Spot Sensor
The Volvo blind spot sensor offers several benefits to the driver. Let’s look at its primary features to provide a better perspective:

1. Real-time Monitoring & Detection
The blind spot sensor remains active throughout your driving journey. It activates automatically with your Volvo vehicle. Then, it actively monitors the road to prevent blind spot accidents.
The sensor has a decent area coverage of 70 meters from the vehicle. That includes the rear, left, and right blind spots. With its active monitoring, you can get notified of any threat within this range of your vehicle.
How does that happen? Well, the Volvo blind spot information system uses radar sensors. They emit waves to detect obstacles in the vehicle’s vicinity and bounce back after detecting something.
2. Data Processing
Besides sensors, another important component of the blind spot information system is its control unit. Also known as the processor or control box, it uses advanced algorithms to understand the incoming signals emitted by the sensors.
This control unit is responsible for analyzing whether a threat exists in your blind spots. If not, you can continue driving. However, if the threat exists, the control box passes digital signals to the alert mechanism.
3. Alerts via Indicators
The Volvo blind spot information system uses LED indicators. They are often mounted on the side-view mirrors via adhesive stickers. These LED indicators alert the drivers following the control unit’s instructions. You can customize these alerts in some Volvo models. This way, you can decide whether visual, audible, or both forms of notifications.
4. Rear-Cross Traffic Alert
The RCTA often comes as a separate driving assistance system. But that’s not the case with Volvo. It comes as a part of the entire blind spot information system. The rear-cross traffic alert helps reverse your vehicle out of the parking spot.
It monitors the oncoming traffic from both sides and provides real-time alerts. This way, you can reverse your vehicle safely without colliding with oncoming cars.
How to Maintain Your Volvo Blind Spot Sensor?
The Volvo blind spot sensor doesn’t require frequent maintenance. However, there are some steps you can take to prolong its lifespan. Here’s what you need to do:

Step 1: Cleaning
Cleaning your sensors can solve most of their problems. Many drivers have reported the error “Volvo blind spot sensor service required.” Most of the time, the problem can be fixed with gentle cleaning.
Remember that the sensors are located at the rear bumpers of your vehicle. That is where dirt, debris, and mud can accumulate. So, use a soft cloth and water to gently wipe the unwanted particles off the sensors.
Step 2: Software Updates
The Volvo blind spot information system uses pre-installed software. This Volvo software requires updates every now and then. Usually, you will get a notification to update it. If not, you can check manually via the Volvo infotainment system. Opt for the Volvo blind spot sensor reset if updating software doesn’t fix the issue.
Step 3: Damage Inspection
Many drivers don’t know the Volvo blind spot sensor location. There’s no need to worry about that. You can read Volvo’s product manual or consult the manufacturer to know its location. Usually, it is mounted inside the rear bumper of your vehicle.
You can inspect it manually without professional assistance. Look for any signs of damage, like dents. Alternatively, you should also look for electrical problems in the system. Preventing these issues at an earlier stage can avoid future problems.
Step 4: Professional Inspection
If the error persists, you can opt for a professional inspection. Usually, you will find local professionals who can help inspect and repair hardware problems. Otherwise, you can set an appointment with a Volvo company representative. The latter is the better option as it is mostly covered by the warranty, preventing extra costs.
What’s The Best Alternative for Volvo Blind Spot Sensor?
Are you looking for a Volvo blind spot sensor replacement? Then, you can get an aftermarket blind spot monitoring system and retrofit it in your Volvo vehicle. Yes, it is that easy!
First, let’s see why you need a Volvo blind spot sensor alternative:
- Its maintenance and repairs can be pretty expensive since its spare parts are not readily available in the market.
- It can be difficult to keep track of regular software updates, leading to false alarms and system errors.
- Professional inspection may often require specifically Volvo company representatives, which can be inaccessible for many people.
