Natural resources form the basis of our existence on this planet. The objectives of our policy are for these resources to be used sparingly and in a manner which takes the requirements of both nature and humanity into account.
Our declared policy is integrated environmental protection. This policy starts at the root causes and encompasses in its management decisions all the consequences for the environment which could arise from production processes or the products themselves.
You too can help to protect the environment by operating your Mercedes-Benz in an environmentally responsible manner. Operating conditions and your individual driving style to a large extent influence fuel consumption and the rate of engine, brake, and tire wear. To reduce fuel consumption and the rate of wear, please consider the following:
• Avoid short trips.
• Make sure that the tire pressures are always correct.
• Avoid frequent, abrupt acceleration.
• Do not carry any unnecessary weight.
• Remove ski holders and roof racks once you no longer need them.
• Do not warm up the engine with the car stationary.
• Shift gears such that each gear is used only up to 2/3 of its maximum engine speed.
• Keep an eye on the vehicle’s fuel consumption.
