erational in the winter, use winter diesel.
It is available at gas stations during winter
months.
The standard fuel filter heating prevents the
supply of fuel from stalling during driving.

BMW X5 with BMW Advanced
Diesel
The concept
BMW Advanced Diesel reduces nitrogen oxides
in the diesel exhaust of your vehicle by injecting
the reducing agent diesel exhaust fluid into the
exhaust line. In the catalytic converter, a chem‐
ical reaction occurs that minimizes nitrogen ox‐
ides.
In order to be able to start the engine in the usual
way, there must be a sufficient supply of diesel
exhaust fluid in the separate reservoir.
System heating
In order to bring the system to operating tem‐
perature after a cold start of the engine, the au‐
Online Edition for Part no. 01 40 2 606 735 - 03 11 500
tomatic transmission shifts into the next higher
gear at a later point.
Reserve display
A display in the instrument panel informs you
about the remaining distance can be covered
with the amount of fuel currently in the tank.
The reserve display appears approx.
1,000 miles/1,600 km before the tank is empty.
As soon as the reserve display has appeared in
the instrument panel, have the diesel exhaust
fluid refilled to prevent the engine from being
unable to restart.
Diesel exhaust fluid at minimum
Even with a display of -- mls, the engine will con‐
tinue to run, provided that it is not switched off,
and all other operating requirements are met,
e.g. sufficient fuel.
No engine start
Do not drive until the displayed remaining
distance runs out. Otherwise, it may not be pos‐
sible to restart the engine.◀
