Points to remember

Risk of accident

You must observe the legal requirements for the country in which you are driving when operating a mobile phone in the vehicle. If it is permitted to operate a mobile phone while the vehicle is in motion, only do so when road and traffic conditions allow. You could otherwise be distracted from the traffic conditions, cause an accident and injure yourself and others. For reasons of safety, use only hands-free mode to operate the telephone while the vehicle is in motion. If you use hands-free mode to make a call, you must continue to drive carefully, close all the windows and prevent any disruptive noises. If you wish to make a telephone call without using hands-free mode, you must stop or park the vehicle. Do not stop or park in areas where stopping and parking are forbidden.

	Risk of injury
Excessive electromagnetic radiation may constitute a health hazard to yourself and others. Use of an exterior aerial gives consideration to the current scientific discussion surrounding the possible health risk posed by electromagnetic fields.
