2027 Mercedes-Benz CLA Safety and Driver-Assist Features
Every 2027 Mercedes-Benz CLA comes standard with core collision-avoidance technology: Active Brake Assist with autonomous emergency braking, Blind Spot Assist Plus with Exit Warning, the Lane Keeping Function, the Evasive Steering Function and Distance Assist DISTRONIC adaptive cruise control (Mercedes-Benz USA). For drivers commuting between Bonita and El Cajon, that means these protections are built in rather than locked behind upgrades. Optional MB.DRIVE packages then add steering support, automated lane changes, a 360-degree camera and point-to-point city assistance.
Driver-assist and safety systems are supplemental aids and are not a substitute for safe, attentive driving. Their effectiveness depends on weather, road, and traffic conditions and other factors. Always obey traffic laws and stay attentive to the road. See your owner’s manual for system details and limitations.
