Eco driving profile ⇒ Driving profile selection and 4MOTION Active Control .
Avoid driving at full throttle
Never drive the vehicle at its top speed. The drag coefficient increases at excessively high speeds.
This in turn increases the force needed to move the vehicle.
Reduce idling
Pull away immediately with low engine speeds. If you are stopped for a long period, do not allow the
engine to idle but switch it off, e.g. when in a traffic jam or at a railway crossing.
In vehicles with an activated start/stop system, the engine can switch off automatically when the
vehicle is stopping and when the vehicle is stationary ⇒ Start/stop system .
Refuel moderately
A full fuel tank increases the weight of the vehicle. A fuel tank that is half or two thirds of the way
full is sufficient for journeys in urban traffic in particular.
Avoid short journeys
A cold engine has very high fuel consumption. The optimum operating temperature is reached only
after driving a few kilometres. The fuel consumption is above average at very low ambient
temperatures, e.g. in winter ⇒ Fig. 97 . Plan journeys economically and combine short journeys.
Carry out regular maintenance
Regular maintenance is an essential prerequisite for economical driving and increases the service life
of the vehicle.
Observe the tyre pressures
Low tyre pressures does not just mean greater wear, but also increase the rolling resistance of the
tyres and thus the fuel consumption. Use optimised rolling resistance tyres.
Adjust the tyre pressure according to the load. Observe the information on the tyre pressure sticker
⇒ Useful information about wheels and tyres
Tyre Pressure Loss Indicator or Tyre Pressure Monitoring System ⇒ Tyre monitoring system .
Use low viscosity engine oils
Fully synthetic engine oils with a low viscosity decrease frictional resistance in the engine and are
distributed better and more quickly, especially during cold starts.
Do not drive with unnecessary loads in the vehicle
You can reduce fuel consumption by clearing out the luggage compartment before setting off, for
example by removing empty drink crates or unused child seats.
To keep the vehicle's air resistance as low as possible, remove any add-on parts and equipment such
as ski racks, bicycle racks and roof carriers once you have finished using them.
