Mercedes C320 owner's manual: Control system

Control system

▼ Control system

The control system is activated as soon as the SmartKey in the starter switch is turned to position 1. The control system enables you to

• call up information about your vehicle
• change vehicle settings

For example, you can use the control system to find out when your vehicle is next due for service, to set the language for messages in the instrument cluster display, and much more.

i The displays for the audio systems (radio, CD player) will appear in English, regardless of the language selected.

Warning!

A driver’s attention to the road and traffic conditions must always be his/her primary focus when driving.

For your safety and the safety of others, selecting features through the multifunction steering wheel should only be done by the driver when traffic and road conditions permit it to be done safely.

Bear in mind that at a speed of just 30 mph (approximately 50 km/h), your vehicle is covering a distance of 44 feet (approximately 14 m) every second.

The control system relays information to the multifunction display.
