tion is insufficient, harmful exhaust gases can
enter into the vehicle. The exhaust gases con‐
tain carbon monoxide, an odorless and color‐
less but highly toxic gas. In enclosed areas, ex‐
haust gases can also accumulate outside of
the vehicle. There is danger to life. Keep the
exhaust pipe free and ensure sufficient ventila‐
tion.◀

Fuel recommendation General information
Depending on the region, many gas stations
sell fuel that has been customized to winter or
summer conditions. Fuel that is available in
winter helps make a cold start easier, for exam‐
ple.
Information ATTENTION
Even fuels that conform to the specifica‐
tions can be of low quality. This may cause en‐
gine problems, e.g., poor engine start-up be‐
havior, poor handling and/or poor performance.
There is a risk of damage to property. In case
of engine problems, switch gas stations or use
a brand name fuel with a higher octane rat‐
ing.◀
Gasoline
General information For the best fuel efficiency, the gasoline
should be sulfur-free or very low in sulfur con‐
tent.
Fuels that are marked on the gas pump as con‐
taining metal must not be used.Fuels with a maximum ethanol content of
10 %, i. e., E10, may be used for refueling.
Ethanol should meet the following quality
standards:
US: ASTM 4806–xx
CAN: CGSB-3.511–xx
xx: comply with the current standard in each
case.
Information ATTENTION
Do not press the Start/Stop button after
refueling with the wrong fuel. Furthermore, the
catalytic converter is permanently damaged.

refuel or add the following in the case of gaso‐
line engines:▷Leaded gasoline.▷Metallic additives, e.g., manganese or iron.
Do not press the Start/Stop button after refuel‐
ing with the wrong fuel. Contact a dealer’s
service center or another qualified service cen‐
ter or repair shop.◀
ATTENTION
Incorrect fuels can damage the fuel sys‐
tem and the engine. There is a risk of damage
to property. Do not use a fuel with a higher
ethanol percentage than recommended or one
with other types of alcohol, e.g., M5 to M100.◀

BMW Advanced Diesel
The concept BMW Advanced Diesel reduces nitrogen ox‐
ides in the diesel emissions by injecting diesel
exhaust fluid into the exhaust system. A chem‐
ical reaction takes place inside the catalytic
converter that minimizes nitrogen oxides.
The vehicle has a tank system that can be refil‐
led.
To be able to start the engine as usual, there
must be an adequate diesel exhaust fluid.
Warming up the system
In order to warm the engine up to its operating
temperature after a cold start, the Steptronic
transmission may subsequently shift up to the
next higher gear.
Displays in the instrument cluster
Reserve indication This display in the instrument cluster provides
information about the distance that can still be
driven with the current reserve level.
Do not continue driving to the limit of the re‐
maining travel distance. It is not possible to re‐
start the engine after switching it off.▷Lamp white: refill with diesel
exhaust fluid at the next op‐
portunity.▷Lamp yellow: not enough
diesel exhaust fluid present.
The remaining range is dis‐
played in the instrument
cluster. Immediately refill
with diesel exhaust fluid.
Diesel exhaust fluid on minimum
▷The remaining range is dis‐
played in the instrument
cluster: add diesel exhaust
fluid. The engine will con‐
tinue to run as long as it isnot switched off and all
other operating conditions
are satisfied; sufficient fuel,
for example.
System malfunction
A Check Control message is displayed when
there is a system not working.
Have the diesel exhaust fluid
replenished
BMW recommends that diesel exhaust fluid be
added by the dealer’s service center within the
course of regular maintenance.
In addition it may be necessary to have the
fluid replenished several times under particular
circumstances, for example, if the vehicle is
driven in a particularly sporty style or if it is
driven at high altitudes.
The diesel exhaust fluid must be replenished
as soon as the reserve display appears in the
instrument cluster to avoid not being able to
restart the engine.
Diesel exhaust fluid at low
temperatures
Due to its physical properties, it is possible
that the diesel exhaust fluid may also need to
be replenished between regular maintenance
appointments if it is exposed to temperatures
under + 23 ℉/- 5 ℃. In this case, add diesel ex‐
haust fluid only immediately before driving off.
At temperatures below + 12 ℉/- 11 ℃, the fill‐
ing level cannot be measured in some cases.
Replenishing diesel exhaust fluid
yourself in exceptional cases
General information You can replenish diesel exhaust fluid yourself
in exceptional cases, for example, to get to
your scheduled service.
