set
the parking brake and place the transmission
in position P or neutral to prevent the car from
moving.◀
Frequent starting in quick succession
Avoid repeated futile attempts at starting
the car and avoid starting the car frequently in
quick succession. Otherwise, the fuel is not

the danger of overheating and damaging the
catalytic converter.◀

vehicle remains stationary. Start driving at mod‐
erate engine speeds.

selves.◀

erwise, the vehicle could roll. On steep upward
and downward inclines, further secure the vehi‐
cle, for example, by turning the steering wheel in

Fuel
Fuel quality
Refuel with unleaded fuel only
Do not use leaded fuel as this would per‐
manently damage the catalytic converter.
◀
Do not refuel with ethanol
Do not refuel with E85, i.e., fuel with an
ethanol content of 85 %, or with Flex Fuel, as this
would damage the engine and fuel supply sys‐
tem.◀
Required fuel
Super Premium Gasoline/AKI 91 or AKI
89
BMW recommends AKI 91 or 89.
Gasoline with lower AKI
The minimum AKI Rating is 89.
If you use gasoline with this minimum AKI Rat‐
ing, the engine may produce knocking sounds
when starting at high outside temperatures.
This has no effect on the engine life.
Minimum fuel grade
Do not use any gasoline below the mini‐
mum specified fuel grade; otherwise, engine
damage may occur.◀
Use high-quality brands
Field experience has indicated significant differ‐
ences in fuel quality: volatility, composition, ad‐
ditives, etc., among gasolines offered for sale in
the United States and Canada.
Fuels containing up to and including 10 % etha‐
nol or other oxygenates with up to 2.8 % oxygen
by weight, that is, 15 % MTBE or 3 % methanol
plus an equivalent amount of co-solvent, will not
void the applicable warranties with respect to
defects in materials or workmanship. Minimum fuel grade
The
use of poor-quality fuels may result in
driveability, starting and stalling problems es‐
pecially under certain environmental conditions
such as high ambient temperature and high al‐
titude.
Should you encounter driveability problems
which you suspect could be related to the fuel
you are using, we recommend that you respond
by switching to a recognized high-quality brand
such as gasoline that is advertised as Top Tier
Detergent Gasoline.
Failure to comply with these recommendations
may result in unscheduled maintenance.◀ Seite 242
