For enhanced safety, the front and rear seat shoulder belts of the Lexus RX have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Chevrolet Blazer doesn’t offer pretensioners for its rear seat belts.
The RX has a standard Secondary Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Blazer doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.
Over 200 people are killed each year when backed over by motor vehicles. The RX has standard Intuitive Parking Assist with Automatic Braking that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Blazer doesn’t offer backup collision prevention brakes.
To deliver safety and visibility under dusty conditions the Lexus RX’s backup monitor has a standard rear washer to keep the view clear. A camera washer system costs extra on the Chevrolet Blazer.
Both the RX and Blazer have rear cross-traffic warning, but the RX has Parking Support Brake (automatically applies the brakes) to better prevent a collision when backing near traffic. The Blazer’s Rear Cross Traffic Alert doesn’t automatically brake.
The RX’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Blazer doesn’t offer a driver alert monitor.
Both the RX and the Blazer have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, available all wheel drive and around view monitors.
