Refueling
232
Refueling
Switch off the engine before refueling.
When handling fuel, always observe all
applicable precautionary measures and regula-
tions. Never transport reserve fuel containers in
the vehicle. These could become leaky and
cause an explosion or a fire in an accident.<
Fuel filler door
Opening
1.Open the fuel filler door. To do this, briefly
press the lower edge.
2.Turn the fuel filler cap counterclockwise.
3.Place the fuel filler 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 crush the band attached to the
cap; otherwise, the cap may not properly
seal and fuel vapors can escape.<
A message
* is displayed if the cap is loose or
missing.
Releasing manually
If an electrical malfunction should occur, you
can unlock the fuel filler door manually.
1.Open the right-hand side panel in the cargo
bay.
2.Pull the knob with the gas pump symbol.
Observe the following when refueling
When handling fuels, follow the safety
precautions posted at the filling station.
Otherwise, there is a danger of personal injury
or property damage.<
When refueling, insert the filler nozzle com-
pletely into the filler pipe. Avoid raising the filler
nozzle during refueling, otherwise this leads to
>premature pump shutoff
>a reduced efficiency of the fuel-vapor
recovery system.
The fuel tank is full when the filler nozzle clicks
off the first time.

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 use leaded gasoline, otherwise
damage to the catalytic converter will
result.
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 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
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
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 pressure
Information for your safety
The condition of the tires and the maintenance
of the specified tire pressure are crucial not only
to the tire's service life, but also to driving com-
fort and most importantly, driving safety.
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 increases.
Check the tire inflation pressure regularly
and correct it as needed, even on the
compact tire
*: at least twice a month and before
starting long trips. If you fail to observe this pre-
caution, you may be driving on tires with incor-
rect tire pressures, a condition that can not only
compromise your vehicle's driving stability, but
also lead to tire damage and the risk of an acci-
dent. Do not drive with depressurized, i.e. flat
tires, except run-flat tires. A flat tire will seri-
ously impair your vehicle's handling and braking
response. Attempts to drive on a flat tire can
lead to a loss of control over the vehicle.<
After correcting the tire inflation pressure,
reinitialize the Flat Tire Monitor, refer to
page92, or reset the Tire Pressure Monitor,
refer to page94.<
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 and tire brands respectively
approved and recommended by BMW; a list of
these is available from your BMW Sports Activ-
ity Vehicle Center. tion pressure for your tires, observe the follow-
ing:
>Tire sizes of your vehicle
>Load conditions
>Maximum allowable driving speed
Tire inflation pressures for speeds
up to 100 mph/160 km/h
For normal driving up to 100 mph/160 km/h,
adjust pressures to the respective tire inflation
pressures listed on the following pages in the
column Traveling speeds up to max. of
100 mph/160 km/h to achieve optimum driving
comfort.
These pressure specifications can be found on
the door post when you open the driver's door.
The permissible top speed for these tire
inflation pressures is 100 mph/160 km/h.
Do not exceed this speed, otherwise tire dam-
age and accidents may result.<
Tire inflation pressures for speeds
above 100 mph/160 km/h
In order to drive at maximum speeds in
excess of 100 mph/160 km/h, please
observe, and, if necessary, adjust tire pressures
for speeds exceeding 100 mph/160 km/h from
the relevant table on the following pages.
Otherwise tire damage and accidents could
occur.<

Tire identification marks
Knowledge of the labeling on the side of the tire
makes it easier to identify and choose the right
tires.
Tire size
Speed letter
Q = up to 100 mph/160 km/h
T = up to 118 mph/190 km/h
H = up to 131 mph/210 km/h
V = up to 150 mph/240 km/h
W = up to 167 mph/270 km/h
Y = up to 186 mph/300 km/h
Tire Identification Number
Tires with DOT codes meet the guidelines
of the US Department of Transportation.
DOT code:
Tire age
The manufacturing date of tires is contained in
the tire coding: DOT ... 1207 indicates that the
tire was manufactured in week 12 of 2007.
BMW recommends that you replace all tires
after 6 years at most, even if some tires may last
for 10 years.
Uniform Tire Quality Grading
Quality grades can be found where applicable
on the tire sidewall between tread shoulder and
maximum section width. For example:
Tread wear 200 Traction AA
Temperature A
DOT Quality Grades
Tread wear
Traction AA A B C
Temperature A B C
All passenger car tires must conform to
Federal Safety Requirements in addition
to these grades.<
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov-
ernment test course. For example, a tire graded
150 would wear one and one-half (1γ) times as
well on the government course as a tire graded
100. The relative performance of tires depends
upon the actual conditions of their use, how-
ever, and may depart significantly from the
norm due to variations in driving habits, service
practices and differences in road characteris-
tics and climate.
Traction
The traction grades, from highest to lowest,
are AA, A, B, and C.
These grades represent the tire's ability to stop
on wet pavement, as measured under con-
trolled conditions on specified government test
surfaces of asphalt and concrete. A tire marked
C may have poor traction performance.
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration, cor-
nering, hydroplaning, or peak traction charac-
teristics.< e.g.

Temperature
The temperature grades are A, the highest, B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions
on a specified indoor laboratory test wheel.
Sustained high temperature can cause the
material of the tire to degenerate and reduce
tire life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds to
a level of performance which all passenger car
tires must meet under the Federal Motor Vehi-
cle Safety Standard No. 109. Grades B and A
represent higher levels of performance on the
laboratory test wheel than the minimum
required by law.
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Excessive speed,
underinflation, or excessive loading, either sep-
arately or in combination, can cause heat
buildup and possible tire failure.<
RSC – run-flat tires
You will recognize run-flat tires by a circular
symbol containing the letters RSC on the side
of the tire, refer to page239.
M+S
Winter and all-season tires.
These have better winter properties than sum-
mer tires.
XL
Indicates specially reinforced tires.
Tire condition
Inspect your tires frequently for tread wear,
signs of damage and for foreign objects lodged
in the tread. Check the tread depth.
Minimum tread depth
The tread depth should not drop below 0.12 in/
3 mm, although, for example, European legisla-
tion only specifies a minimum tread depth of 0.063 in/1.6 mm. At tread depths below 0.12 in/
3 mm there is an increased risk of high-speed
hydroplaning, even when only small amounts of
water are present on the road surface.
When winter tires wear down past a tread depth
of 0.16 in/4 mm, they become perceptibly less
suitable for winter conditions. For the sake of
safety, new tires should be installed.
Wear indicators at the tread-groove base, refer
to arrow, are distributed over the tire's circum-
ference and are marked on the side of the tire
with TWI – Tread Wear Indicator. If the tire tread
has been driven down to the wear indicators, a
tread depth of 0.063 in/1.6 mm has been
reached.
Wheel/tire damage
Please note that low-profile tires cause wheels,
tires and suspension parts to be more suscep-
tible to road hazards and consequential dam-
ages.
Unusual vibrations encountered during normal
vehicle operation can indicate tire failure or
some other vehicle defect. This can, for exam-
ple, be caused by driving over curbs. These
kinds of problems may also be signaled by other
changes in vehicle response, such as a strong
tendency to pull to the left or right.
In these cases, reduce speed immedi-
ately and have wheels and tires thor-
oughly checked. To do so, drive carefully to the
nearest BMW Sports Activity Vehicle Center or
tire shop that works according to BMW repair
procedures with correspondingly trained per-
sonnel. If necessary, have the vehicle towed
there. Otherwise, tire damage can be extremely
dangerous to vehicle occupants and other road
users.<
