The Blind Spot Information System (BLIS) in your Volvo XC90 is a crucial safety feature designed to alert you to vehicles hidden in your blind spots. Regularly testing and maintaining the components of this system ensures it functions optimally, enhancing your driving safety.

How to Test the BLIS Components

Start by checking the sensors, usually located on the rear side panels. Clean any dirt or debris that might obstruct their view. Next, activate the system by turning on your vehicle and observing the indicator lights on your side mirrors. To test the alerts, have a friend drive a vehicle alongside you in adjacent lanes; the BLIS warning light should illuminate when their car enters your blind spot.

Steps to Replace BLIS Components

  1. Identify the faulty part: Often, it’s one of the sensors or the indicator light on the side mirrors.
  2. Disconnect the battery: To ensure safety, disconnect the car battery before working on electrical components.
  3. Remove the faulty sensor or light: Access the sensor by removing the interior panels near the rear side panels or mirror housing.
  4. Install the new component: Securely connect and mount the new sensor or indicator light.
  5. Reconnect the battery and test: Turn on your vehicle and verify the system is operational as described in the testing section.

Maintaining your Volvo XC90’s BLIS system is a simple but effective way to stay safe on the road. If you’re unsure about performing these steps yourself, consult a Volvo specialist or authorized service center.
