function Switching on/off ........................... 129 Introduction 21 Protection of the environment General notes H Environmental note Daimler's declared policy is one of compre- hensive environmental protection. Our objectives are to use the natural resour- ces which form the basis of our existence on this planet sparingly and in a manner which takes the requirements of both nature and humanity into consideration. You too can help to protect the environment by operating your vehicle in an environmen- tally-responsible manner. Fuel consumption and the rate of engine, transmission, brake and tyre wear depend on the following factors: Roperating conditions of your vehicle Ryour personal driving style You can influence both factors. Therefore, please bear the following in mind: Operating conditions: Ravoid short trips, as these increase fuel consumption. Robserve the correct tyre pressure. Rdo not carry any unnecessary weight in the vehicle. Rremove the roof rack once you no longer need it. Ra regularly serviced vehicle will contribute to environmental protection. You should therefore adhere to the service intervals. Rall maintenance work should be carried out at a qualified specialist workshop. Personal driving style: Rdo not depress the accelerator pedal when starting the engine. Rdo not warm up the engine when the vehicle is stationary. Rdrive carefully and maintain a safe distance from the vehicle in front. Ravoid frequent, sudden acceleration and braking. Rchange gear in good time and use each gear only up to Ô of its maximum engine speed. Rswitch off the engine in stationary traffic. Rmonitor the vehicle's fuel consumption. Returning an end-of-life vehicle EU countries only: Mercedes-Benz will take back your old vehicle to dispose of it in an environmentally-respon- sible manner in accordance with the Euro- pean Union (EU) End of Life Vehicles Direc- tive. There is a network of return points and dis- assembly plants available. You can return your vehicle to these plants free of charge. This makes a valuable contribution to the recycling process and the conservation of resources. For further information on recycling old vehi- cles, recovery and the terms of the policy, visit the Mercedes-Benz homepage. Genuine Mercedes-Benz parts H Environmental note Daimler AG also supplies reconditioned assemblies and parts which are of the same quality as new parts. For these, the same war- ranty applies as for new parts. ! Airbags and seat belt tensioners, as well as control units and sensors for these restraint systems, may be installed in the following areas of your vehicle: Rdoors Rdoor pillars Rdoor sills Rseats Rdashboard Rinstrument cluster Rcentre console 22 Introduction Do not install accessories such as audio systems in these areas. Do not carry out repairs or welding. You could impair the operating efficiency of the restraint sys- tems. Have accessories retrofitted at a qualified specialist workshop. If you use parts, tyres and wheels as well as accessories relevant to safety which have not been approved by Mercedes, the operating safety of the vehicle could be jeopardised. This could lead to malfunctions in safety-rel- evant systems, e.g. the brake system. Only use genuine Mercedes-Benz parts or parts of equal quality. Only use tyres, wheels and accessories that have been specifically approved for your vehicle. Mercedes-Benz tests genuine parts and con- version parts and accessories that have been specifically approved for your vehicle for their reliability, safety and suitability. Despite ongoing market research, Mercedes-Benz is unable to assess other parts. Mercedes-Benz accepts no responsibility for the use of such parts in Mercedes-Benz vehicles, even if they have been independently or officially approved. In Germany, certain parts are only officially approved for installation or modification if they comply with legal requirements. This also applies to some other countries. All gen- uine Mercedes-Benz parts meet the approval requirements. The use of non-approved parts may invalidate the vehicle's general operating permit. This is the case: Rif they cause a change of the vehicle type from that for which the vehicle's general operating permit was granted Rif other road users could be endangered Rif the emission or noise levels are adversely affected Always specify the vehicle identification num- ber (VIN) (Y page 338) and the engine num- ber (Y page 338) when ordering genuine Mercedes-Benz parts. Owner's Manual General notes Before you first drive off, read this Owner's Manual carefully and familiarise yourself with your vehicle. For your own safety and a longer vehicle life, follow the instructions and warning notices in this manual. Disregarding them may lead to damage to the vehicle or personal injury. Vehicle equipment This Owner's Manual describes all models and all standard and optional equipment available for your vehicle at the time of pub- lication of the Owner's Manual. Country-spe- cific differences are possible. Note that your vehicle may not be fitted with all features described. This is also the case for systems and functions relevant to safety. Therefore, the equipment on your vehicle may differ from that in the descriptions and illustrations. The original purchase contract documenta- tion for your vehicle contains a list of all of the systems in your vehicle. Should you have any questions concerning equipment and operation, please consult a Mercedes-Benz Service Centre. The Owner's Manual and Service Booklet are important documents and should kept in the vehicle. Operating safety Important safety notes G WARNING If you do not have the prescribed service/ maintenance work or necessary repairs car- ried out, this could result in malfunctions or system failures. There is a risk of an accident. Always have the prescribed service/mainte- nance work as well as necessary repairs car- ried out at a qualified specialist workshop. Introduction 23 G WARNING If you switch off the ignition while driving, safety-relevant functions are only available with limitations, or not at all. This could affect, for example, the power steering and the brake boosting effect. You will require considerably more effort to steer and brake. There is a risk of an accident. Do not switch off the ignition while driving. G WARNING Modifications to electronic components, their software as well as wiring could effect their function and/or the operation of other net- worked components. This could in particular also be the case for systems relevant to safety. They might not function properly any more and/or jeopardise the operational safety of the vehicle. There is an increased risk of an accident and injury. Do not attempt to modify the wiring as well as electronic components or their software. Always have work on electrical and electronic components carried out at a qualified special- ist workshop. There is a risk of damage to the vehicle if: Rthe vehicle becomes stuck, e.g. on a high kerb or an unpaved road Ryou drive too fast over an obstacle, e.g. a kerb or a hole in the road Ra heavy object strikes the undercarriage or parts of the chassis. In situations like this, the body, the undercar- riage, chassis parts, wheels or tyres could be damaged without the damage being visible. Components damaged in this way can unex- pectedly fail or, in the case of an accident, no longer withstand the strain they are designed to. If the underbody panelling is damaged, com- bustible materials such as leaves, grass or twigs can gather between the underbody and the underbody panelling. If these materials come in contact with hot parts of the exhaust system for an extended period, they can catch fire. Have the vehicle checked and repaired imme- diately at a qualified specialist workshop. If on continuing your journey you notice that driving safety is impaired, pull over and stop the vehicle immediately, paying attention to road and traffic conditions. In such cases, visit a qualified specialist workshop. Declarations of conformity Wireless vehicle components The following information applies to all com- ponents of the vehicle and the COMAND sys- tem which receive and/or transmit radio waves: The components of this vehicle which receive and/or transmit radio waves are compliant with the basic requirements and other rele- vant provisions of Directive 1999/5/EC. You can obtain further information from any Mercedes-Benz Service Centre. Electromagnetic compatibility The electromagnetic compatibility of the vehi- cle components has been checked and certi- fied according to the currently valid version of Directive 72/245/EEC or the equivalent ECE Regulation ECE-R 10. Diagnostics connection The diagnostics connection is only intended for the connection of diagnostic equipment at a qualified specialist workshop. G WARNING If you connect equipment to a diagnostics connection in the vehicle, it can affect the operation of the vehicle systems. This may affect the operating safety of the vehicle. There is a risk of an accident. Do not connect any equipment to a diagnos- tics connection in the vehicle.
