Neither NHTSA (National Highway Traffic Safety Administration) nor the IIHS (Insurance Institute for Highway Safety) has crash-tested the 2010 Mercedes-Benz CL-Class-because it's "an ultra-low volume car," says Cars.com. Its high safety ratings from TheCarConnection.com are based on its structural similarity to the Mercedes S-Class sedan.
Cars.com notes the CL's standard safety features include "antilock brakes with brake assist, side-impact airbags for the front and rear seats, a driver's knee airbag, side curtain airbags," and "an electronic stability system."
A trio of systems in the 2010 CL-Class use radar to detect imminent collisions. Brake Assist Plus will increase the level of pressure you apply to the brake pedal if it determines you're closing in on the car ahead too quickly. Pre-Safe will take other steps, such as tightening seatbelts and preparing the airbags, if it senses a collision is unavoidable. Kelley Blue Book describes the CL's active cruise control as "a programmable cruise control system with two onboard radar sensors" that automatically maintains the proper distance from cars ahead." But it can also bring the CL to a complete stop in traffic, starting again when the car ahead begins to move. This system also includes Blind Spot Assist, which monitors both blind spots and warns the driver whenever a turn signal is activated.
The 2010 CL-Class also has standard ultrasonic parking sensors and a backup camera. Cars.com notes that the Mercedes-Benz 2010 CL600 also has "adaptive brake lights that flash when the brake assist or stability systems are activated, in order to gain the attention of following drivers."
New safety features for the 2010 CL include Attention Assist, which senses when drivers may be drowsy and signals them to take a break; night vision; adaptive headlamps; and a feature that helps the CL-Class stay in its intended lane by using gentle braking.
