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
oxides.
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
automatic 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 end of the
tank.
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
continue to run, provided that it is not switched
off, and all other operating requirements are
met, e.g. sufficient fuel.
Do not drive until the displayed remaining
distance runs out. Otherwise, it may not
be possible to restart the engine. <
Incorrect fueling
The warning lamp lights up:
The reservoir has been filled with an
incorrect fluid.
Please contact your BMW Sports Activity Vehi-
cle Center.
Having diesel exhaust fluid refilled
Your BMW Sports Activity Vehicle Center refills
the diesel exhaust fluid as part of the regular
maintenance. If you adhere to this maintenance
schedule, it is usually not necessary to refill any
fluids between the maintenance dates.
Under certain circumstances, e.g. due to a par-
ticularly sporty driving style or operation of the
vehicle at high altitudes, it may be necessary to
refill fluids between maintenance dates.
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.
You can have the fluid refilled by a BMW Sports
Activity Vehicle Center.
Diesel exhaust fluid at low
temperatures
Due to its physical properties, it may be
necessary to replenish the level of diesel
