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, for instance helps make a cold start
easier.
Gasoline
General
information For the best fuel efficiency, the gasoline
should be sulfur-free or very low in sulfur conj tent.
Fuels that are marked on the gas pump as conj 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 stanj dards:

catalytic converter is permanently damaged.
There is a risk of damage to property. Do not refuel or add the following in the case of gasojline engines:'yLeaded gasoline.'yMetallic additives, for instance manganese
or iron.
Do not press the Start/Stop button after refuelj ing with the wrong fuel. Contact a dealerss
service center or another qualified service cenj
ter or repair shop.'

If drivability problems are encountered, we recjommend switching to a high quality gasolinebrand and a higher octane grade n AKI numjber n for a few tank fills. To avoid harmful enj
gine deposits, it is highly recommended to purchase gasoline from Top Tier retailers.
Failure to comply with these recommendations
may result in the need for unscheduled mainj
tenance.'

BMW
Advanced
Diesel
Concept
BMW Advanced Diesel reduces nitrogen oxj
ides in the diesel emissions by injecting diesel exhaust fluid into the exhaust system. A chemj
ical reaction takes place inside the catalytic converter that minimizes nitrogen oxides.
General
information
The vehicle has a tank system that can be refilj
led.
To be able to start the engine as usual, there
must be an adequate diesel exhaust fluid.
Diesel exhaust fluid is available at many gas
stations.

General
information
You can replenish Diesel exhaust fluid yourself
in exceptional cases, for instance to get to your
scheduled service.
Safety
information WARNING
Small amounts of ammonia fumes can
escape when opening the diesel exhaust fluid
container. Ammonia fumes have a pungent odor and irritate skin, mucous membranes, andeyes. There is a risk of injury. Do not inhale esjcaping ammonia fumes. Avoid the contact ofarticles of clothing, skin or eyes with diesel exj
haust fluid. Do not swallow any diesel exhaust
fluid. Keep children away from diesel exhaust
fluids.'

The tank is full when the fill level in the botj
tle no longer changes. It is not possible to overfill.5.Pull back the bottle, see arrow, and unjscrew it.6.Replace the fuel cap and turn it clockwise.7.Close the fuel filler flap.

General
information
The tire characteristics and tire inflation presj

Safety
information
WARNING
A tire with too little or no tire inflation
pressure may heat up significantly and sustain
damage. This will have a negative impact on aspects of handling, such as steering andbraking response. There is a risk of an accij
dent. Regularly check the tire inflation presj
sure, and correct it as needed, for instance
twice a month and before a long trip.'

3.Correct the tire inflation pressure if the curjrent tire inflation pressure value deviates
from the specified value.4.Check whether all valve caps are screwed onto the tire valves.
