Important safety notes

WARNING
Always remember that you must concentrate primarily on driving the vehicle. The driver's concentration must always be directed primarily at road traffic. For your own safety and that of others, we recommend that you stop the vehicle at a safe place and in accordance with the traffic conditions before making or accepting a phone call.
Comply with all legal requirements if you use the telephone while driving. Use the handsfree system and only use the telephone when road, weather and traffic conditions permit. In some jurisdictions, it is forbidden for drivers to use mobile phones while driving.
Only operate the audio system or COMAND (Cockpit Management and Data System) in compliance with all legal requirements and when the road, weather and traffic conditions permit. You may otherwise not be able to observe the traffic conditions, endangering yourself and others.
Remember that your vehicle covers a distance of 44 feet (approximately 14 m) a second when it is traveling at only 30 mph (approximately 50 km/h).
