What is Blind Spot Monitor (BSM)?

This is one of Lexus’ most recent safety monitoring systems which uses the sensors installed behind the rear bumper to assist the driver. It uses radar sensors to find vehicles moving in an adjacent lane (rear view mirror) in an area where the blind spot is not visible. 

BSM alerts the driver if the turn indicator is on by turning on an indicator in the door mirror on the relevant side of the vehicle. The BSM function effectively when the main switch is on. And also when the vehicle speed is greater than approximately 10 mph (16 km/h).

Currently, the Lexus GS, RX 450h, and the new Lexus NX luxury crossover all come equipped with the Blind Spot Monitor system.

Components of Blind Spot Monitor

1. BSM Button

You activate or deactivate the device by pressing the switch. When the switch is turned on, the indicator lights up and the buzzer plays. This button controls both the Blind Spot Monitor and the Rear Cross Traffic Warning features.

2. Outside Rear-View Mirror Indicators

When a vehicle is detected in a blind spot of the outside rear-view mirrors or is coming quickly from behind into a blind spot, the outside rear-view mirror indicator on the detected side will light up.

3. Rear Cross Traffic Alert buzzer 

The buzzer sounds from behind the right-hand back seat when a vehicle appears from the right or left rear of the car.

What Does the BSM Light on a Lexus Mean?

In a Lexus, the BSM light stands for the Blind Spot Monitor warning light. The BSM warning indicators are located in the left and right side mirrors.

And it illuminates when the BSM system identifies a vehicle in the driver’s blind spot to alert them to a potential threat. As long as the car is identified in the blind spot, the light will remain on; once it is no longer in the blind spot, it will go out.

Also, the blind spot monitor is intended to assist drivers in safer lane changes and lessen the possibility of accidents brought on by blind spots.

On some Lexus models, it is an optional feature that may not be available on all trim levels or model years.

Increased convenience:

By eliminating the need to physically check blind spots, the BSM system also makes driving more convenient.

The BSM system instantly checks your blind spots for you, saving you from having to turn your head or look over your shoulder. When driving on congested highways or in heavy traffic, this feature can be particularly useful.

2. Enhanced Comfort:

By reducing tension and fatigue, using the BSM system can also improve your driving comfort. You can relax and concentrate on driving without worrying about blind spots when you know that the BSM system is working to identify other vehicles.

When Should I Use the BSM System in my Lexus?

On the highway, the BSM system is especially helpful when shifting lanes. It helps to notify you with the BSM light on the corresponding side mirror as you get close to the lane you want to shift into if there are any vehicles in your blind spot. This enables you to make a safer lane shift and check your blind spot.

2. When Driving in Traffic

If you’re driving in heavy traffic, the BSM system can help you avoid collisions with vehicles that may be close to your car but out of your line of sight.

By keeping the BSM system enabled, you can be more aware of your surroundings and make safer driving decisions.

3. When Driving in Poor Weather Conditions

It can be more difficult to see other cars on the road when there is bad weather present. In this situation, the BSM system can be useful in spotting and warning you of vehicles in your blind zone.
