Lexus Blind Spot Monitor: Beeping And Your Safety

Lexus is a division of Toyota that manufactures luxury vehicles. One of the safety features of Lexus vehicles is the Blind Spot Monitor (BSM), which uses radar sensors in the rear quarters of the vehicle to detect objects in the driver's blind spot. When the BSM is turned on, a solid light appears in the side-view mirror to increase the driver's awareness. If the driver signals to change lanes while a vehicle is in the blind spot, the solid light flashes as a warning.

While some Lexus drivers appreciate the BSM feature, others have complained about the lack of an audible alert, such as a beeping noise, in addition to the visual warning. Some have suggested that the absence of a beeping noise may be due to cost-cutting measures, while others have proposed aftermarket solutions to enable a beeping noise. However, it is important to note that relying solely on the BSM feature is not recommended, and drivers should always look over their shoulder and use their turn signal when changing lanes.

Lexus blind spot monitor: beeping vs flashing

Lexus is a subsidiary of Toyota, so its vehicles' blind spot monitoring systems are similar to Toyota's. Lexus's Blind Spot Monitor (BSM) is a standard feature on most new Lexus models, including the Lexus GS, LX, RX, ES, GX, LS, NX, RC, and LC. The BSM system uses radar sensors in the rear quarters of the vehicle to detect vehicles approaching from adjacent lanes. If a vehicle is in the Lexus's blind spot, a solid light appears in the side-view mirror to increase the driver's awareness.

If the driver signals to change lanes while a vehicle is in the blind spot, the light flashes to warn the driver. The system can also be customised to provide an audible warning, such as a beep, in addition to the flashing light. However, some Lexus models, like the NX200t, do not have an audible warning. In these cases, the BSM system only provides a visual warning, with the light in the side-view mirror flashing to alert the driver.

Some Lexus drivers have expressed a desire for an audible warning, such as a beep, in addition to the flashing light. Aftermarket modifications to add a beeping sound to the BSM system have been discussed, but they may be challenging to implement. Overall, while some drivers prefer a beeping sound for added warning, others find it annoying and distracting.

In addition to the BSM, Lexus vehicles are also equipped with a Rear Cross-Traffic Alert system. This system uses the same radar sensors as the BSM to detect oncoming vehicles when the car is backing out of a parking spot or driveway. This system provides both visual and audible warnings if cross-traffic is detected.

How to turn on the blind spot monitor in a Lexus

Lexus's Blind Spot Monitor (BSM) is a standard feature on most new Lexus models, including the Lexus GS, LX, RX, ES, GX, LS, NX, RC, and LC. The BSM uses radar sensors in the rear quarters of the vehicle to detect vehicles approaching from adjacent lanes. If a vehicle is detected in the driver's blind spot, a solid light appears in the side-view mirror. If the driver signals to change lanes while a vehicle is in the blind spot, the light flashes to warn the driver.

How to turn on the BSM in different Lexus models

• Lexus GS: Use the steering wheel controls to toggle over to the settings menu in your MID (the gear icon). Use the up and down arrows on your meter control switch to select "BSM". Each time the "." is selected on the meter control switch, BSM is either turned on or off. Look for the green BSM indicator light on the dash to confirm that the feature is on.
• Lexus LX: Similar to the Lexus GS, use the left and right arrows on the meter control switches to select the gear icon (settings). Then, use the up and down arrows on the meter control switches to select BSM and turn it on by selecting the "."
• Lexus RX: Use the steering wheel meter control switches and MID to turn on or off the BSM.
• Lexus ES: Simply push the BSM button located under the outside mirror controls or to the left of your knee if you're sitting inside the car.
• Lexus GX 460: First, push the button on the GX steering wheel. Next, toggle up or down until you see BSM on the MID, then press "Enter."
• Lexus IS: Press the BSM button inside the driver's door. When you see the green light, you'll know it's turned on.
• Lexus LS: Press the BSM button conveniently located inside the driver's door to the left of the steering wheel. The green light indicates that the feature is on.
• Lexus NX: Press the BSM button inside the driver's door. The green light indicates that the feature is on.
• Lexus RC: Press the BSM button located inside the driver's door, similar to the Lexus NX, IS, and ES.

It's important to note that while the BSM can improve safety, drivers should not rely solely on it. Always look over your shoulder and use your turn signal when changing lanes.

Customising blind spot monitor alerts

The Lexus Blind Spot Monitor (BSM) is a standard feature on most new Lexus models, including the Lexus GS, LX, RX, ES, GX, LS, NX, RC, LC, and NX200t. The BSM uses radar sensors in the rear quarters of the vehicle to detect vehicles approaching from adjacent lanes, alerting the driver with a solid light in the side-view mirror and, in some cases, an audible warning.

While the BSM is designed to enhance safety and driving perception, some drivers may prefer to customise the alerts to their preferences. Here are some ways to customise your BSM alerts:

• Visual Alerts: The BSM in Lexus vehicles typically provides a visual alert in the form of a solid light in the side-view mirror when a vehicle enters the blind spot. This light flashes as a warning if the driver signals to change lanes while an object is in the blind spot. This visual alert can be turned on or off using the steering wheel controls and the multi-information display (MID). Toggle over to the settings menu in the MID (indicated by a gear icon) and use the arrow buttons to select "BSM". Each press of the button will turn the feature on or off, and a green BSM indicator light on the dashboard confirms that it is active.
• Audible Alerts: While some Lexus models, such as the Lexus ES, provide an audible warning when the BSM detects an object, other models like the NX200t and Avalon do not have this feature. Some drivers may prefer an audible alert, as it can be more noticeable than a visual alert. However, others may find it distracting or annoying. Unfortunately, it does not appear that Lexus vehicles have the option to customise the type of alert, and models that only provide visual alerts cannot be modified to include an audible warning without significant aftermarket alterations.
• Seat Vibration: Some drivers who desire a more noticeable alert have suggested seat vibration as an alternative to an audible warning. This feature is present in some BMW models, vibrating the steering wheel when the BSM is activated. While Lexus does not appear to offer this feature, it may be a more intuitive option for those who find visual alerts insufficient.
• Rear Cross-Traffic Alert: While not directly customisable, it is important to note that the BSM system in Lexus vehicles includes a Rear Cross-Traffic Alert feature. This uses the same sensors as the BSM to detect oncoming vehicles when backing up from a parking spot or driveway. This feature provides both visual and audible warnings if cross-traffic is detected and can be turned off with the push of a button, which may be useful in certain driving conditions.

In summary, while Lexus vehicles do not offer a wide range of customisation options for BSM alerts, drivers can toggle the feature on or off and, in some models, benefit from the additional Rear Cross-Traffic Alert warnings. For those seeking alternative alert types, such as an audible beep or seat vibration, aftermarket modifications or considering vehicles from other manufacturers may be necessary.

Blind spot monitor limitations

Blind Spot Monitoring (BSM) is a useful safety feature in Lexus vehicles that can help alert drivers to vehicles in their blind spot. While this feature can improve safety, it is important to understand its limitations.

One limitation of the BSM system is that it relies on radar sensors in the rear quarters of the vehicle to detect approaching vehicles. These sensors have a limited range, and there may be areas around the vehicle that are not covered by the sensors. Additionally, the system may not detect smaller objects or vehicles that are moving at a high speed.

Another limitation is that the BSM system may not always provide an audible alert when a vehicle is in the blind spot. Some Lexus models only provide a visual warning, such as a flashing light in the side-view mirror, which may be less noticeable to the driver. While the system may beep when the turn signal is activated, this is not the case for all models, and some drivers may prefer a more prominent alert.

It is also important to note that the BSM system is not a substitute for safe driving practices. Drivers should always look over their shoulder, use their turn signals, and check their mirrors before changing lanes. Relying solely on the BSM system can be dangerous, as it may not detect all objects or vehicles in the surrounding area.

Furthermore, the BSM system may not work properly in certain driving conditions or when the vehicle is towing a trailer. In these situations, it may be necessary to turn off the system temporarily. Additionally, the system may not function correctly if the sensors are obstructed or damaged, or if there are issues with the vehicle's electrical system.

Finally, the BSM system may not be available on all Lexus models, and the method for activating it may vary depending on the specific model and year of the vehicle. It is important for drivers to consult their owner's manual to understand the specifics of their vehicle's BSM system and its limitations.
