motorway. The car should then be driven for
approximately 20 minutes more.
NOTE
The following may arise during regenera-
tion:
•
a smaller reduction of engine power
may be noticed temporarily
•
fuel consumption may increase tem-
porarily
•
a smell of burning may arise.
When regeneration is complete the warning
text is cleared automatically.
Use the parking heater* in cold weather so
that the engine reaches normal operating
temperature more quickly.
IMPORTANT
If the filter is completely filled with parti-
cles, it may be difficult to start the engine
and the filter is non-functional. Then there
is a risk that the filter will need to be
replaced.

Economical driving
Driving economically means driving smoothly
while thinking ahead and adjusting your driv-
ing style and speed to the prevailing condi-
tions.
•
Avoid driving with open windows.
•
Do not use winter tyres when the winter
season is over.
•
Avoid sudden unnecessary acceleration
and heavy braking.
•
Drive with the correct air pressure in the
tyres and check it regularly - select ECO
tyre pressure for best results, see Tyres -
approved tyre pressures (p. 457).
•
Drive in the highest gear possible, adap-
ted to the current traffic situation and
road - lower engine speeds result in lower
fuel consumption. Use the gear shift indi-
cator (p. 272)
15 .
•
Remove unnecessary items from the car -
the greater the load the higher the fuel
consumption.
•
Use engine braking to slow down, when it
can take place without risk to other road
users.
•
Choice of tyres can affect fuel consump-
tion - seek advice on suitable tyres from a
dealer.
•
A roof load and ski box increase air resis-
tance, leading to higher fuel consumption
- remove the load carriers when not in
use.
•
Do not run the engine to operating tem-
perature at idling speed, but rather drive
with a light load as soon as possible - a
cold engine consumes more fuel than a
warm one.
•
High speed results in increased fuel con-
sumption - the wind resistance increases
with speed.

ronmental philosophy (p. 20) and Fuel con-
sumption and CO2 emissions (p. 454).
WARNING
Never switch off the engine while moving,
such as downhill, this deactivates impor-
tant systems such as the power steering
and brake servo.
