Driving and the environment

CautionNever fully drain the fuel tank because the irregularity of the fuel supply may
cause ignition problems. This allows unburnt fuel to enter the exhaust
system, which could cause overheating and damage the catalytic converter.
For the sake of the environment
Even when the emission control system is working perfectly, there may be a
smell of sulphur from the exhaust gas under some conditions. This depends
on the sulphur content of the fuel used. Quite often the problem can be
solved by changing to another brand of fuel.Diesel engine particulate filter*
The diesel engine particulate filter eliminates soot produced
by burning diesel.The diesel engine dust filter eliminates most of the soot from the exhaust gas
system. Under normal driving conditions, the filter cleans itself. If the driving
conditions do not allow the filter to clean itself (for example, multiple short
trips) the filter will be obstructed by dust and pollen and the indicator
for
the diesel engine particulate filter indicator will light up. See section on
Warning Lamps.
WARNING
•The diesel engine particulate filter may reach extremely high tempera-
tures; it should not enter into contact with flammable materials under-
neath the vehicle. Failure to comply could result in fire.
Caution
•The vehicle is not designed for refuelling with blends of FAME fuel
(biodiesel) over 7% in accordance with DIN 51628. The diesel particulate
filter is damaged when this blend percentage is exceeded.Economical and environmentally-friendly
drivingGeneral notes
Fuel consumption depends to a large extent on your personal
driving style.Fuel consumption, environmental impact and engine, brake and tyre wear
depend largely on three factors:•Personal driving style•Conditions of use (weather, road surface)•Te chni cal r eq ui re men ts
By adopting an economical driving style and anticipating the traffic situation
ahead, you can easily reduce fuel consumption by 10-15%. This section
suggests methods of lessening the impact on the environment and reducing
your operating costs at the same time.Foresight when drivingA vehicle uses most fuel when accelerating. If you think ahead when driving,
you will need to brake less and thus accelerate less. Wherev er possible, take
