For enhanced safety, the front and rear seat shoulder belts of the Mercedes CLA 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 Nissan Maxima doesn’t offer pretensioners for its rear seat belts.
The CLA’s optional pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Maxima doesn’t offer pre-crash pretensioners.
The CLA offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Maxima doesn’t offer all-wheel drive.
Both the CLA and Maxima have rear cross-traffic warning, but the CLA has Active Brake Assist (automatically applies the brakes) to better prevent a collision when backing near traffic. The Maxima’s Rear Cross Traffic Alert doesn’t automatically brake.
Both the CLA and the Maxima have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front wheel drive, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors, available lane departure warning systems and around view monitors.
