Refueling
210
Refueling
Always switch off the engine before refu-
eling, otherwise, fuel cannot be added to
the tank and a message will be displayed.<
Take all precautionary measures and
observe all applicable regulations when
handling fuel. Do not carry any spare fuel con-
tainers in your vehicle. They can develop a leak
and cause an explosion or cause a fire in the
event of an accident.<
Fuel filler door
Opening
1.Open fuel filler door. To do so, lightly press
the rear edge.
2.Turn the gas cap counterclockwise.
3.Place the gas cap in the bracket attached to
the fuel filler door.
Closing
Fit the cap and turn it clockwise until you clearly
hear a click.
Do not pinch the band attached to the
cap, otherwise the cap cannot be closed
properly and fuel vapors can escape. A mes-
sage will be displayed if the gas cap is loose or
missing.<
Manually releasing the fuel filler door
In the event of a malfunction, you can release
the fuel filler door manually:
Coupe
1.Remove the cover from the right-hand side-
wall of the cargo bay.
2.Pull the knob with the fuel pump symbol.
The fuel filler door is released.
Convertible
1.Loosen the right-hand cargo bay trim panel
by turning the screws by 90°, see arrow.
2.Slightly lift the top section of the panel. It is
not necessary to remove the entire panel.
3.Pull the knob with the fuel pump symbol.
The fuel filler door is released.
Observe the following when refueling
When handling fuels, follow the safety
instructions provided at filling stations,
otherwise there is a risk of personal injury or
property damage.<
When refueling, insert the filler nozzle com-
pletely into the filler pipe. Avoid lifting the filler
nozzle while filling the tank, as that would lead
to

>reduced efficiency of the fuel-vapor recov-
ery system.
The fuel tank is full when the filler nozzle clicks
off the first time.
Fuel tank capacity
Approx. 16.1 US gallons/61 liters, including the
reserve capacity of 2.1 US gallons/8 liters.
Refuel as soon as possible once your
cruising range falls below 30 miles/
50 km, otherwise engine functions are not
ensured and damage can occur.<
Fuel specifications
Do not fill the tank with leaded fuel, as this
would cause permanent damage to the
catalytic converter.
Do not fill the tank with E85, i.e. fuel containing
85 % ethanol, nor with FlexFuel. Otherwise the
engine and fuel supply system will be dam-
aged.<
Required fuel
Super Premium Gasoline/AKI 91
This gasoline is highly recommended.
However, you may also use gasoline with less
AKI. The minimum AKI Rating is:
>328i/xi: 87
>335i/xi: 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.
Do not use any gasoline below the speci-
fied minimum fuel grade. Otherwise the
engine could be damaged.<
Use high-quality brands
Field experience has indicated significant dif-
ferences in fuel quality: volatility, composition,
additives, etc., among gasolines offered for sale
in the United States and Canada. Fuels contain-
ing up to and including 10 % ethanol 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.
The use of poor-quality fuels may result in
driveability, starting and stalling problems
especially under certain environmental condi-
tions such as high ambient temperature and
high altitude.
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 also result in unscheduled maintenance.<

Tire inflation pressures
Information for your safety
It is not merely the tires' service life, but also
driving comfort and, to a great extent, driving
safety that depend on the condition of the tires
and the maintenance of the specified tire pres-
sure.
Check the tire inflation pressure regularly
and correct it, if necessary: at least twice a
month and before starting long trips. If you fail
to observe this precaution you may be driving
on tires with incorrect tire pressures, a condi-
tion that can not only compromise your vehi-
cle's driving stability, but also lead to tire dam-
age and the risk of an accident. Do not drive
with deflated, i.e. flat tires, except when using
Run-Flat Tires. A flat tire will seriously impair
your vehicle's handling and braking response.
Attempts to drive on a flat tire can lead to loss of
control over the vehicle.<
Checking pressure
Only check tire inflation pressure when the
tires are cold. This means after a maximum of
1.25 miles/2 km driving or when the vehicle has
been parked for at least 2 hours. When tires are
warm, the tire inflation pressure is higher.
After correcting tire inflation pressures,
always reinitialize the Flat Tire Monitor,
refer to page92.<
Inflation pressure specifications
The tables below provide all the correct inflation
pressures for the specified tire sizes at ambient
temperature.
The inflation pressures apply to the tire
sizes approved and tire brands recom-
mended by BMW; a list of these is available
from your BMW center.<
For correct identification of the right tire infla-
tion pressures, observe the following:
>Tire sizes for your vehicle>Load conditions
>Maximum allowable driving speed
Tire inflation pressures for driving up to
100 mph or 160 km/h
For normal driving up to 100 mph or 160 km/h
and to achieve optimum driving comfort, adjust
pressures to the respective tire inflation pres-
sures listed on the following pages in the col-
umns for traveling speeds up to a maximum of
100mph or 160km/h.
These tire inflation pressures can also be found
on the driver's-side door post when the driver's
door is open.
The maximum permissible speed for
these tire pressures is 100 mph or
160 km/h. Do not exceed this speed, otherwise
tire damage and accidents could occur.<
Tire inflation pressures for driving
above 100 mph or 160 km/h
In order to drive at maximum speeds in
excess of 100 mph or 160 km/h, adjust
pressures to the respective tire inflation pres-
sures listed on the following pages in the col-
umns for traveling speeds including those
exceeding 100 mph or 160 km/h. Otherwise tire
damage and accidents could occur.<
Observe all national and local maximum speed
limits, otherwise violations of the laws could
occur.
