Traffic jam assistant.
The traffic jam assistant helps you in monotonous situations on the motorway. In dense traffic at speeds of up to 40 km/h, the system allows you to move easily along with the traffic and stay relaxed.
It automatically maintains the desired distance from the vehicle ahead and regulates the car's speed right down to standstill − as well as providing active steering support, too. This helps you stay on track, providing you keep at least one hand on the steering wheel.
The traffic jam assistant is part of the optional equipment ConnectedDrive Services.
