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
>Premature pump shutoff
>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
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.<
Gasoline engine
Approx. 16.1 US gallons/61 liters, including the
reserve capacity of 2.1 US gallons/8 liters.
Diesel engine
Approx. 16.1 US gallons/61 liters, including the
reserve capacity of 1.7 US gallons/6.5 liters.
Fuel specifications
Gasoline engine: required fuel
Do not refuel with leaded fuel; otherwise,
the catalytic converter will be damaged.
Do not fill the tank with E85, i.e. fuel containing
85Ξ ethanol, nor with FlexFuel. Otherwise, the
engine and fuel supply system will be dam-
aged.<
Super Premium Gasoline/AKI 91
This gasoline is highly recommended.
However, you may also use gasoline with less
AKI. The minimum AKI Rating is:
>323i, 328i/xDrive: 87
>335i/xDrive: 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 10Ξ ethanol or other
oxygenates with up to 2.8Ξ oxygen by weight,
that is, 15Ξ MTBE or 3Ξ methanol plus an
equivalent amount of cosolvent, will not void the
applicable warranties with respect to defects in
materials or workmanship.
The use of poor-quality fuels may result in
drivability, starting and stalling problems
especially under certain environmental condi-
tions such as high ambient temperature and
high altitude.
Should you encounter drivability problems
which you suspect could be related to the fuel
y o u a r e u s i n g , w e r e c o m m e n d t h a t y o u r e s p o n d
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.<

Diesel exhaust fluid at the
minimum level
Even if the display indicates -- mls, the engine
continues running if it is not switched off and if
all other requirements continue to be met, e.g. a
sufficient supply of fuel.
Do not drive to the end of the indicated
distance. Otherwise, it will not be possible
to start the engine again after switching it off.<
Wrong fluid
A warning lamp lights up:
The wrong fluid was filled into the res-
ervoir.
Please contact your BMW center.
Having the diesel exhaust fluid refilled
Diesel exhaust fluid is refilled by your BMW
center during regular service. If the service
intervals are adhered to, it generally does not
need to be refilled between service appoint-
ments.
Under certain conditions, e.g. especially fre-
quent accelerations or operation of the vehicle
at high altitudes, it may become necessary to
refill the fluid between service appointments.
When this reserve display appears in the instru-
ment cluster, have diesel exhaust fluid refilled to
avoid not being able to start the engine.
You can have the fluid refilled by a BMW center.
Diesel exhaust fluid at low
temperatures
Because of its physical properties, it may
be necessary to refill diesel exhaust fluid
between regular service appointments at tem-
peratures below +237/-56.
The need to add fluid is indicated by the reserve
display in the instrument cluster, refer to
page204.<
Refilling diesel exhaust fluid in
exceptional cases
To be able to reach the next BMW center, you
can refill diesel exhaust fluid yourself while
adhering to the following warnings.
Do not come into contact with diesel
exhaust fluid as it can lead to skin or eye
irritations. Wear goggles and gloves, if neces-
sary. Follow the safety instructions on the bot-
tle.
Vapors with a sharp odor can escape from the
bottle or container when it is opened. Before
refilling, completely close the windows and
doors of the vehicle to prevent the vapors from
intruding into the interior. If handling diesel
exhaust fluid in an enclosed area, ensure that
the room is well ventilated.
After handling diesel exhaust fluid, wash your
hands thoroughly; otherwise, for example, inad-
vertently touching your eyes may lead to eye
irritations.
If eye irritations occur, rinse the eyes thoroughly
with water and consult a physician if necessary.
If diesel exhaust fluid comes into contact with
the surface of your vehicle, rinse the affected
areas with water to prevent surface damage.
Keep diesel exhaust fluid away from children.<
Suitable diesel exhaust fluid
>Preferred: BMW Diesel Exhaust Fluid.
Diesel exhaust fluid can be refilled conve-
niently with this bottle and its special
adapter.
>Alternatively: NOx reduction agent AUS 32
You can obtain diesel exhaust fluid from your
BMW center.

Wheels and tires
224
Recommended tire brands
Certain makes of tire are recommended by
BMW for each tire size. They are marked with a
clearly visible BMW designation on the sidewall
of the tire.
When properly used, these tires meet the high-
est standards in terms of safety and handling
characteristics.
Special characteristics of winter tires
BMW recommends winter tires for driving on
winter roads or at temperatures below +45 7/
+7 6. Although all-season M+S tires provide
better winter traction than summer tires, they
generally fail to provide the same levels of cold-
weather performance as winter tires.
Pay attention to speed
Always comply with the speed limit for the
winter tires mounted on your car; failure
to do so could result in tire damage and acci-
dents.<
If the car is capable of speeds higher than that
permitted for the winter tires, a label stating the
maximum permitted speed for the mounted
tires must be displayed in your field of view.
Specialist tire dealers and your BMW center
can supply these labels.
Storage
Always store wheels and tires in a cool, dry
place with as little exposure to light as possible.
Always protect tires against all contact with oil,
grease and fuels. Do not exceed the maximum
tire inflation pressure indicated on the sidewall
of the tire.
Swapping wheels between axles
BMW advises against swapping wheels
between the front and rear axles, even if all tires
have the same size, as this could impair driving
characteristics. If the tires are of mixed sizes,
swapping wheels between the axles is not per-
missible.
Snow chains*
Only certain fine-link snow chains have been
tested by BMW, classified as safe for use and
recommended. Consult your BMW center for
more information.
Snow chains must be mounted in pairs and on
the rear wheels only. Observe the manufac-
turer's instructions when mounting snow
chains. Do not exceed a speed of 30 mph or
50 km/h.
Do not initialize the Flat Tire Monitor if
snow chains are mounted; otherwise, the
instrument might issue an incorrect reading.
When driving with snow chains, you may find it
helpful to activate DTC temporarily, refer to
page86.<

Maintenance

Socket for Onboard
Diagnosis OBD
On the driver's side is an OBD socket for check-
ing components relevant to the composition of
the vehicle's emissions.
Emissions
The warning lamp lights up:
The vehicle is producing higher emis-
sions. The trip can be continued. Have
the car checked as soon as possible.
Canadian models display this warning
lamp.
The lamp flashes under certain conditions. This
indicates excessive misfiring in the engine. If
this happens, you should reduce your speed
and visit your nearest BMW center as soon as
possible. Severe engine misfiring can quickly
lead to serious damage of emissions-related
components, especially the catalytic converter.
The warning lamp comes on if the gas
cap is not properly tightened and the
OBD system assumes that fuel vapor
is escaping. Make sure that the gas cap is cor-
rectly positioned and close it until it audibly
clicks.
Data memory
Your vehicle records data about the operation,
faults, and user settings. These data are stored
in the vehicle and in extract form, in the remote
control, and can be read out using suitable
devices at your BMW center. The data that are
read out are used to support service proce-
dures and repairs or to optimize and expand
vehicle functions. If you have a BMW Assist
contract, certain vehicle data can also be trans-
mitted directly from the vehicle in order to
enable the desired services.
