Fuel specifications
Never used leaded gasoline; it will perma-
nently damage the catalytic converter.
Do not use E85, i.e. fuel that consists of 85%
ethanol, or Flex Fuel. Otherwise permanent
damage to the engine and the fuel supply sys-
tem will result.<
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 87.
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 affect on the engine life.
Do not use gasoline below the specified
minimum quality, otherwise engine dam-
age can result.<
Use high-quality brands
Field experience has demonstrated significant
differences in fuel quality: volatility, composi-
tion, additives, etc., among gasolines offered for
sale in the United States and Canada. Fuels
containing 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 cosolvent, will not
void the applicable warranties with respect to
defects in materials or workmanship.
The use of poor-quality fuels may result in
problems relating to drivability and start-
ing, and to a tendency to stall, especially under
certain environmental conditions such as high
ambient temperature and high altitude.
Should you encounter drivability 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.<

Recommended tire brands
Certain tire makes are recommended by BMW
depending on the tire size. You can recognize
these from the clearly visible BMW marking on
the tire sidewall.
When used properly, these tires comply with
the most demanding standards for safety and
vehicle response.
Run-flat tires
When mounting new tires, or changing from
summer to winter tires or vice versa, use run-flat
tires for your own safety. In addition, no spare
tire is available in case of a flat tire. Your BMW
center will be glad to advise you.
Special characteristics of winter tires
BMW recommends winter tires for use in cold
winter driving conditions. 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.
Watch speed
Always observe the maximum permissi-
ble speed for the winter tires, otherwise
tire damage may occur, which can result in acci-
dents.<
Storage
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 side wall of
the tire.
Rotating wheels between axles
BMW does not recommend moving the front
wheels to the rear or vice versa, as otherwise
the handling characteristics may be impaired.
With tires of different makes and types
* such a
change is not permissible.
Snow chains*
BMW only tests certain fine-link snow chains,
classifies them as road-safe and recommends
them. Consult your BMW center for more infor-
mation.
These snow chains are approved exclusively for
use in pairs on the rear wheels with the tire size:
>245/50 R 17
>245/45 R 18
Observe the manufacturer's instructions when
mounting snow chains. Do not exceed a speed
of 30 mph/50 km/h with the chains mounted.
Do not initialize the Flat Tire Monitor after
installing snow chains as this could cause
the Flat Tire Monitor to malfunction.
When driving with snow chains, it may be prac-
tical to briefly activate DTC, refer to page84.<

Socket for OBD Onboard
Diagnostics interface
Components which are decisive for the
exhaust-gas composition can be checked via
the OBD socket with a device.
This socket is located under a cover on the left
side of the driver's footwell, directly under the
instrument panel.
Exhaust-gas values
The warning lamp lights up:
The vehicle emissions are raised. The
trip can be continued. Have the vehicle
checked as soon as possible.
Display of the previously described
malfunction in Canadian models.
The lamp flashes under certain conditions. This
is a sign of excessive misfiring of the engine. In
this case you should reduce speed and drive to
the nearest BMW center as soon as possible.
Heavy engine misfiring causes serious damage
to the emission-relevant components, espe-
cially the catalytic converter, within a short time.
If the fuel filler cap is not properly tight-
ened, the OBD system will assume that
fuel vapor escapes. Then a display lights up. If
the cap is then tightened, the display will go out
within a few days.<
Data recorders
Your vehicle may be equipped with one or sev-
eral measuring and diagnosis modules, or with
a device for recording or transmitting certain
vehicle data or information. If you have also sub-
scribed to BMW Assist, certain vehicle data can be transmitted or recorded to enable corre-
sponding services.

Insufficient distance or excessive pressure or
temperature can damage parts of the vehicle or
can result in water penetration. Follow the oper-
ating instructions for the high-pressure clean-
ing jets.<
When using high-pressure cleaning jets,
do not remain in one place for a long time
and be sure to maintain a distance of at least
12 in/30 cm from sensors, e.g. Park Distance
Control sensors or radar sensors.<
Hand washing
When washing the vehicle by hand, use plenty
of water and car washing shampoo. Clean the
vehicle with gentle pressure using a sponge or a
washing brush.
Before cleaning the windshield, deacti-
vate the rain sensor or switch off the igni-
tion to prevent unwanted wiper operation.<
Follow local guidelines for washing vehi-
cles by hand.<
Headlamps
Do not rub dry and never use abrasives or
strong solvents to clean the covers.
Loosen dirt, e.g. insects, with shampoo or
insect remover and wash away with plenty of
water.
Use a window deicer to remove accumulated
ice and snow, not a scraper.
Windows
Use a glass cleaner to clean the inside and out-
side surfaces of the windows and the glass sur-
faces of the mirrors.
Do not use quartz-containing cleansers
to clean glass surfaces of the mirrors.<
Convertible top care
The appearance and service life of the convert-
ible top depend on proper care and operation.
Please follow these instructions:
>Never stow the convertible top in the con-
vertible top compartment when it is wet or frozen, since this can cause water marks,
mildew stains, and scuff marks.
>If water marks do occur on the headliner,
remove them with a microfiber cloth and
interior cleanser.
>When parking for long intervals in enclosed
spaces, make sure there is sufficient venti-
lation.
>Remove bird droppings immediately
because their caustic properties have a cor-
rosive effect on the convertible top and can
damage the rubber seals.
Do not use stain remover, paint thinner,
solvents, gasoline, or the like to remove
stains. These substances can damage the rub-
ber coating. Improper care and cleaning can
cause leaks to develop in the convertible top
and its seams.<
In the event of more serious soiling, use a spe-
cial convertible top cleaner.
When doing so, follow the manufacturer's
directions for use.
After three to five washings, treat the convert-
ible top with sealant.
Caring for the vehicle finish
Regular care helps your vehicle retain its value
and protects the paint from the long-term
effects of aggressive substances.
Regionally occurring environmental factors can
affect and damage vehicle finish. It is therefore
important to tailor the frequency and extent of
your car care accordingly.
Immediately remove particularly aggressive
substances such as spilled fuel, oil, grease,
brake fluid, tree resin, or bird droppings; other-
wise, they may damage your paint.
Repairing paint damage
Repair stone damage or scratches imme-
diately, depending on the severity of the
damage, to prevent the formation of rust.<
BMW recommends having paint damage pro-
fessionally repaired using Genuine BMW finish
materials in accordance with factory guidelines.
