For enhanced safety, the front and rear seat shoulder belts of the Mazda CX-5 have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision. The Chevrolet Blazer doesn’t offer pretensioners for its rear seat belts.
The Mazda CX-5 has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags help prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Blazer doesn’t offer a front passenger side knee airbag.
The CX-5 has a standard Secondary Collision Reduction System, 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 CX-5 has a standard Rear Smart Brake Support 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 provide maximum traction and stability on all roads, All-Wheel Drive is standard on the CX-5. But it costs extra on the Blazer.
Both the CX-5 and Blazer have Rear Cross Traffic Alert, but the CX-5 has Smart Braking Support - Rear Crossing (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 CX-5’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 CX-5 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 and available around view monitors.
