Lexus BSM Light [Meaning, Importance, & How to Enable/Disable]

Driving has become safer and more enjoyable as a result of technological advancements. Has your Lexus’ dashboard been illuminated by the “BSM” light? How did you handle it if so?

As the name implies, Blind Spot Monitors detect vehicles approaching from behind or on the sides by using radar sensors. A warning light will be illuminated on the appropriate side of the vehicle when a vehicle is detected.

Lexus BSM Light [Meaning, Importance, & How to EnableDisable]

It is my intent to explain in this article what the BSM light means, what it does, and how it is enabled and disabled. You can find out more by reading on.

What Does the Lexus BSM Light Mean?

BSM stands for “Blind Spot Monitor.” The system alerts drivers to other vehicles in their blind spots so they will avoid accidents.

It is a sign that the system is active and working properly when the BSM light illuminates. As long as you see this light, you need not take any action. Your blind spot light will blink if a vehicle has been detected in your blind spot. It is a good idea to check your mirrors before changing lanes and make sure it is safe for you to do so.

Enabling & Disabling Lexus BSM

The BSM system can be enabled and disabled differently on different Lexus models. You can find specific instructions in your owner’s manual.

To enable or disable the system, follow these steps:

  • The MID and steering controls
  • BSM button

The following article will give you a detailed explanation of both ways and the different models.

Steering controls and the multi-information display

The MID settings can be toggled over using the steering wheel controls. The BSM setting can be found by scrolling down the list with the arrow keys.

You can enter the menu by pressing the “OK” button once you’ve found it. You can turn on and off the system using the arrow keys here. After you have made your changes, click the “OK” button to save and exit.

These features are available on Lexus GS, LX, and RX models.

The BSM Button

BSM can be enabled and disabled with a dedicated button on most models. The Lexus button is usually found near the top of the center console or just to the left of the steering wheel inside the driver’s door.

The system can be turned on or off by pressing and holding this button. By looking at the BSM light on your dashboard, you can tell if the system is on or off. When it’s illuminated, the system is running.

There are several Lexus models that use this feature, including IS, GX, NX, RC, ES, and LS.

Your car’s BSM system can be enabled or disabled in pretty much the same way, no matter how you do it. If the “BSM” light is green on your dashboard, you’re good to go.

How to Use the Lexus BSM Light

Drivers can avoid accidents by using the BSM system. You should, however, also pay attention to what is going on around you as well.

How to Use the Lexus BSM Light

Use of the BSM light is necessary in the following instances:

Lane change

Whenever you change lanes, make sure that your mirrors and blind spots are checked. When a car enters your blind spot, the BSM system can illuminate the light.


If you park in a tight space, you may find the BSM system helpful. When a vehicle approaches from behind or from the side, it will illuminate the light.

Nighttime driving

If other cars are not using their headlights, the BSM system can help you see them. When driving on dark or foggy roads, this can be very helpful.

Check the BSM light on your dashboard to see if the system is working properly. The system is activated if it is illuminated.

The Best Way to Adjust Your BSM Settings

You can customize the BSM settings on Lexus vehicles to suit your preferences. The following steps will guide you through customizing your BSM settings:

By pressing the “MENU” button on your steering wheel, you can activate or disable the BSM system.

Once in the BSM menu, you can adjust various settings to make it as customized as you like. Click on “SETTINGS,” followed by “VEHICLE SETTINGS,” and then “BLIND SPOT MONITOR.”

There are three settings that can be altered: BSM sensitivity, rear cross-traffic alert (RCTA), and intuitive parking assist (IPA). By adjusting these settings, you can customize BSM according to your own driving requirements. Use the steering wheel “OK” button to exit the menu.

How to troubleshoot BSM lights

In spite of the fact that the BSM system on your Lexus is designed to function reliably, the BSM light may suddenly illuminate due to a few common issues:

Dirty sensors

You can detect other vehicles in your blind spots using the BSM system located on your rear bumper. These sensors may not function properly if they become dirty or obstructed, resulting in the BSM light turning on.

Faulty wiring

In order for BSM to function properly, connections and wiring are necessary. Unexpected activation of the BSM light can occur if the wiring or connections are faulty.

Batteries with low voltage

Battery voltage is required for the BSM system to function properly. The BSM light may be illuminated if the battery voltage is low.

There are a few troubleshooting steps you can take if your Lexus’ BSM light is not working:

Check the sensors

Ensure that there is no damage or obstruction to the sensors on your rear bumper. A mild detergent and a soft cloth can be used to clean them if they are dirty.

Check the wiring

Make sure the BSM wiring and connections are in good working order and that there is no corrosion or damage. A technician should be consulted if any issues are found.

Check the battery voltage

Make sure the battery voltage is correct by using a multimeter. You should have your battery tested and replaced if necessary if the voltage is low.

For those who are not able to resolve the issue through these troubleshooting steps, they may need to seek professional assistance from a Lexus technician. A BSM technician can diagnose and fix any problems with the system to ensure that it remains reliable and effective.
