If you have refueled with the wrong fuel, contact
your BMW center.

The filler neck is designed for refueling at
diesel fuel pumps.

If the filler nozzle cannot be inserted into your
BMW's filler pipe, please ensure that you are
refueling at a diesel fuel pump and that it is
equipped with a diesel filler nozzle.

In the event the Ultra-Low Sulfur Diesel
fuel cannot be fully inserted into the fuel

filler neck, please contact BMW Roadside
Assistance for instructions on how to add fuel.

tance, refer to page

Winter diesel

To ensure that the diesel engine remains oper-
ational in the winter, please use winter diesel,
which is available at gas stations during winter
months. The fuel filter heating system, included
as a standard feature, prevents disruption of the
fuel supply while driving.

Do not add additives, including gasoline;
otherwise, engine damage may occur.

BMW Advanced Diesel

The concept

BMW Advanced Diesel reduces nitrogen oxide
in the diesel emissions of your vehicle by means
of a mechanism that injects diesel exhaust fluid,
a reduction agent, into the exhaust tract. A
chemical reaction occurs in the catalytic con-
verter that minimizes the nitrogen oxide con-
tent.
To be able to start the engine as usual, a suffi-
cient amount of diesel exhaust fluid must be
present in a separate reservoir.

Warming the system

To warm the system to its operating tempera-
ture after starting with a cold engine, the auto-
matic transmission delays shifting to the next
higher gear, if necessary.

Reserve display

A display in the instrument cluster informs you
about the remaining distance you can drive with
the fluid remaining in the reservoir.

The reserve display appears beginning at
approx. 1,000 miles/1,600 km before the sup-
ply is used up.

When this reserve display appears in the
instrument cluster, have diesel exhaust

fluid refilled to avoid not being able to start the
engine.

Diesel exhaust fluid at the minimum
level

Even if the display indicates -- mls, the engine
continues running if it is not switched off and if
all other requirements continue to be met, e.g. a
sufficient supply of fuel.

Do not drive to the end of the indicated
distance. Otherwise, it will not be possible

to start the engine again after switching it off.
