Does the Lexus RX 350 have blind spot monitoring?
Yes. In the current RX 350 lineup, Blind Spot Monitor with Rear Cross-Traffic Alert is included as part of Lexus Safety System+ 2.5 and is standard across most trims. Some older or base configurations may require upgrading to a higher package to gain BSM.
The RX 350’s safety systems are designed to help detect vehicles in adjacent lanes and warn the driver when changing lanes or backing up. Availability can vary by model year and trim, so checking the exact configuration for a given vehicle is important.
What blind spot monitoring does on the RX 350
How it works
Blind Spot Monitor uses radar sensors mounted in the side mirrors to monitor the lanes beside and behind the vehicle. If another vehicle enters the monitored area, a warning light appears in the corresponding side mirror, and in some configurations an audible alert may accompany the warning. Rear Cross-Traffic Alert helps detect crossing traffic when backing out of parking spaces, issuing warnings to prevent collisions.
Availability by year and trim
Below is a snapshot of how Blind Spot Monitoring with Rear Cross-Traffic Alert has appeared across RX 350 generations and trim levels in recent years. Exact availability can vary by market and option packages.
- 2024 RX 350: Blind Spot Monitor with Rear Cross-Traffic Alert is standard on all trims as part of Lexus Safety System+ 2.5.
- 2020–2023 RX 350: BSM with RCTA was typically standard on higher trims and widely included with Safety System+ 2.5; some base trims in certain markets required optional packages to add the feature.

How to verify on your RX 350
To confirm whether your specific RX 350 has Blind Spot Monitor with Rear Cross-Traffic Alert, use these steps.
- Check the window sticker or the vehicle brochure for “Blind Spot Monitor” and “Rear Cross-Traffic Alert.”
- In the infotainment system, go to Settings or Safety to verify that BSM/RCTA is enabled and view related configuration options.
- Look at the side mirror indicators when you drive; illuminated icons typically signal active BSM, while changes in lane may trigger warnings if a vehicle is detected.
- If buying used, request a VIN-based feature check or a dealer-confirmed feature list to ensure the RX 350 you’re considering includes BSM/RCTA.
Verifying these features helps ensure you have the intended safety equipment for your RX 350.
What to do if your RX 350 lacks BSM
If your model doesn’t include Blind Spot Monitor with Rear Cross-Traffic Alert, review available safety packages for your year and trim. In some cases, BSM may only be available on higher trims or newer model years, so upgrading to a newer RX 350 could be necessary to gain the feature.
Summary
Across recent Lexus RX 350 generations, blind spot monitoring with rear cross-traffic alert is standard on many newer models and available on others through optional packages. If you’re shopping used or evaluating a specific year, confirm the feature on the window sticker or with the dealer to avoid surprises at delivery.
