The Blind Spot Monitor (BSM) system is an advanced safety feature available on Lexus vehicles. It uses sensors to detect other vehicles that are approaching from behind and may be in your blind spot.
When the system detects a vehicle in your blind spot, it sends a signal to the BSM light on your side mirror, which alerts you that there is another vehicle nearby.
The BSM system uses radar sensors mounted on the rear bumper of the car to detect other vehicles. The system can detect other vehicles that are up to 230 feet away and up to 10 feet behind your vehicle.
When the system detects another vehicle in your blind spot, the BSM light on your side mirror will illuminate.
There are several advantages to having a BSM system in your car. One of the main benefits is increased safety on the road.
With the BSM system, you can be alerted to other vehicles that you may not have been able to see otherwise, reducing the risk of accidents when changing lanes or merging onto the highway.
The BSM system can also help reduce stress and anxiety while driving. By having an extra set of eyes on the road, you can feel more confident and secure when driving in heavy traffic or on crowded roads.
How to Enable & Disable Lexus BSM
1. Using the Multi-Information Display
To enable or disable the BSM system using the Multi-Information Display, follow these steps:
- Press the “MENU” button on your steering wheel.
- Use the arrow buttons to navigate to “SETTINGS,”
- Use the arrow buttons to navigate to “VEHICLE SETTINGS,”
- Use the arrow buttons to navigate to “BLIND SPOT MONITOR,”
- Use the arrow buttons to select “ON” or “OFF,” and then press “OK.”
- To exit the menu, press the “OK” button on your steering wheel.
2. The BSM Button
Another way to enable and disable the BSM system in a Lexus vehicle is by using the BSM button. The location of the button may vary depending on the model of the vehicle, but it is usually located near the top of the center console or inside the driver’s door, just to the left of the steering wheel.
To enable or disable the BSM system using the BSM button, simply press and hold the button for a few seconds. When the system is turned on or off, you will be able to see the BSM light on your dashboard. If the light is illuminated, the BSM system is on, and if it is not illuminated, the system is off.
It is important to note that not all Lexus models have the BSM button feature. The models that do include the Lexus IS, GX, NX, RC, ES, and LS.
How to Adjust Your BSM Settings
Lexus vehicles offer several options for customizing your BSM settings to suit your preferences. To customize your BSM settings, follow these steps:
To enable or disable the BSM system using the Multi-Information Display and steering controls, press the “MENU” button on your steering wheel.
Then, use the arrow buttons to navigate to “SETTINGS,” followed by “VEHICLE SETTINGS,” and then “BLIND SPOT MONITOR.” Once you are in the BSM menu, you can adjust various settings to customize the system to your liking.
These settings include BSM sensitivity, rear cross-traffic alert (RCTA), and intuitive parking assist (IPA). Adjusting these settings allows you to fine-tune the BSM system to your specific driving needs. To exit the menu, press the “OK” button on your steering wheel.
When to Use the Lexus BSM Light
1. Changing Lanes Safely
The BSM system can be particularly helpful when changing lanes on highways or busy roads. The system uses sensors to detect any vehicles that may be in your blind spots, alerting you through the BSM light on your dashboard. This can help you avoid collisions and ensure a smooth lane change.
2. Parking and Maneuvering
The BSM system can also be useful for parking and maneuvering your vehicle in tight spaces. The sensors can detect any vehicles or obstacles that may be behind or beside your car, providing you with a warning through the BSM light. This can help you avoid accidents and make parking much easier.
3. Driving at Night or in Low-Visibility Conditions
The BSM system can be especially important when driving at night or in low-visibility conditions such as heavy rain or fog. In these situations, it can be difficult to see vehicles in your blind spots, increasing the risk of accidents. The BSM system can help alert you to any nearby vehicles and provide a sense of safety for you.
Why is the BSM Light Important?
1. Prevents Accidents on the Road
The BSM light can help prevent accidents by alerting you to any vehicles that may be in your blind spots. By using the BSM system and paying attention to the light, you can avoid collisions when changing lanes or merging onto highways.
2. Enhances Safety while Driving
The BSM system can provide safety while driving, help you stay aware of your surroundings, and avoid potential hazards. This can give you greater peace of mind and confidence on the road, making your driving experience safer and more enjoyable.
3. Complements Other Safety Features
This light can also complement other safety features in your Lexus, such as the backup camera and lane departure warning system. By working together, these features can help keep you and your passengers safe while driving.
How to Respond to the BSM Light
1. Check Your Surroundings
When the BSM light turns on, it’s important to check your mirrors and look over your shoulder to ensure that there is no vehicle in your blind spot. This can help you avoid collisions when changing lanes or merging onto highways.
2. Stay Alert
The BSM light helps you to stay alert, this is because it’s important to be aware of your surroundings at all times. Pay attention to other drivers on the road, and be prepared to respond quickly to any potential hazards.

To ensure your safety and the safety of others on the road, it’s important to follow safe driving practices at all times. This includes maintaining a safe following distance, obeying traffic signals and signs, and avoiding distracted driving.
4. Seek Professional Help
If the BSM light continues to turn on or off unexpectedly, it may indicate a problem with the system. In this case, it’s important to seek professional help from a certified Lexus technician to diagnose and fix the issue.
Troubleshooting the BSM Light
While the BSM system on your Lexus is designed to function reliably, there are a few common issues that can cause the BSM light to turn on unexpectedly:
- Dirty sensors: The BSM system uses sensors located on the rear bumper to detect other vehicles in your blind spots. If these sensors become dirty or obstructed, they may not function properly, causing the BSM light to turn on.
- Faulty wiring: Like any electrical system, the BSM system relies on wiring and connections to function properly. If there is a problem with the wiring or connections, it may cause the BSM light to turn on unexpectedly.
- Low battery voltage: The BSM system requires a certain level of battery voltage to function properly. If the battery voltage is low, it may cause the BSM light to turn on.
If you are experiencing issues with the BSM light on your Lexus, there are a few troubleshooting steps you can take:
- Check the sensors: Inspect the sensors on your rear bumper for any signs of damage or obstruction. If they are dirty, clean them carefully with a soft cloth and a mild detergent.
- Check the wiring: Inspect the wiring and connections for the BSM system for any signs of damage or corrosion. If you find any issues, have them repaired by a certified technician.
- Check the battery voltage: Use a multimeter to check the battery voltage. If the voltage is low, have your battery tested and replaced if necessary.
If these troubleshooting steps do not resolve the issue, it may be necessary to seek professional help from a certified Lexus technician. They can diagnose and repair any issues with the BSM system to ensure that it functions reliably and effectively.
The Blind Spot Monitor (BSM) system and the BSM light on a Lexus are essential features that help drivers stay safe on the road. By alerting drivers of potential hazards in their blind spots, the BSM system helps to prevent accidents and promote safer driving practices.
