For enhanced safety, the front seat shoulder belts of the Lexus LX are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The VinFast VF 9 doesn’t offer height-adjustable seat belts.
In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the LX are reminded to check the back seat if they opened the rear door before starting out. The VF 9 doesn’t offer a back seat reminder.
When descending a steep, off-road slope, the LX’s standard CRAWL Control allows you to creep down safely. The VF 9 doesn’t offer CRAWL Control.
Both the LX and VF 9 have rear cross-traffic warning, but the LX has Parking Support Brake (automatically applies the brakes) to better prevent a collision when backing near traffic. The VF 9’s Rear Cross Traffic Alert doesn’t automatically brake.
Both the LX and the VF 9 have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, post-collision automatic braking systems, daytime running lights, lane departure warning systems, blind spot warning systems, around view monitors, rear cross-path warning and driver alert monitors.
