Operation Driving instructions Control and operation of radio transmitters COMAND*, radio and telephone* Warning! Telephones and two-way radios Warning! Catalytic converter G G Please do not forget that your primary responsibility is to drive the vehicle safely. Only operate the COMAND (Cockpit Management and Data System), radio or telephone1 if road, traffic and weather conditions permit. Bear in mind that at a speed of just 30 mph (approximately 50 km/h), your vehicle is covering a distance of approximately 44 feet (approximately 13.5 m) every second. 1 Never operate radio transmitters equipped with a built-in or attached antenna (i.e. without being connected to an external antenna) from inside the vehicle while the engine is running. Doing so could lead to a malfunction of the vehicle's electronic system, possibly resulting in an accident and/or serious personal injury. Your Mercedes-Benz is equipped with monolithic-type catalytic converters, an important element in conjunction with the oxygen sensors to achieve substantial control of the pollutants in the exhaust emissions. Keep your vehicle in proper operating condition by following our recommended maintenance instructions as outlined in your Service Booklet. ! To prevent damage to the catalytic converters, only use premium unleaded gasoline in this vehicle. Any noticeable irregularities in engine operation should be dealt with promptly. Otherwise, excessive unburned fuel may reach the catalytic converter, causing it to overheat and start a fire. Radio transmitters, such as a portable telephone or a citizens band unit should only be used inside the vehicle if they are connected to an antenna that is installed on the outside of the vehicle. Refer to the radio transmitter operation instructions regarding use of an external antenna. Observe all legal requirements. 275
