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 if necessary, including on the
spare wheel
*: at least twice a month and before
starting long trips. Otherwise, driving instability
or tire damage, and therefore accidents, can
result from incorrect tire inflation pressures.<
After correcting the tire inflation pressure,
reinitialize the Flat Tire Monitor, refer to
page80, or reset the Tire Pressure Monitor,
refer to page81.<
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 center.<
For correct identification of the right tire infla-
tion pressure for your tires, observe the follow-
ing:
>Tire sizes for your vehicle
>Load conditions
>Maximum allowable driving speed
Tire inflation pressures for driving
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 for traveling speeds up to a 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 maximum permissible speed for
these tire pressures is 100 mph/
160 km/h. Do not exceed this speed, otherwise
tire damage and accidents could occur.<
Tire inflation pressures for driving
above 100 mph/160 km/h
In order to drive at maximum speeds in
excess of 100 mph/160 km/h, please
note the tire pressures for speeds exceeding
100 mph/160 km/h listed in the relevant column
of the table on the following pages and adjust
your tire inflation pressures as needed. Other-
wise, tire damage and accidents could occur.<
Observe all national and local maximum speed
limits, otherwise violations of the law 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
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
Z = over 150 mph/240 km/h
Tire Identification Number
Tires with DOT codes meet the guidelines of
the US Department of Transportation.
DOT code:
Tire age
The tire's date of manufacture is indicated on
the sidewall:
DOT … 1009 means that the tire was manufac-
tured in week 10 of 2009.BMW recommends replacing all tires at least
every 6 years, even if some tires may last for
10 years. This also concerns the tire of the
spare wheel
*.
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 govern-
ment course as a tire graded 100. The relative
performance of tires depends upon the actual
conditions of their use, however, and may
depart significantly from the norm due to varia-
tions in driving habits, service practices and dif-
ferences in road characteristics 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 controlled
conditions on specified government test sur-
faces 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.< For instance

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.<
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.
Winter tires noticeably loose their suitability for
winter use below a tread depth of 0.16 in/4 mm. 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 center or tire shop that works
according to BMW repair procedures with cor-
respondingly trained personnel. If necessary,
have the vehicle towed there. Otherwise, tire
damage can be extremely dangerous to vehicle
occupants and other road users.<
New wheels and tires
Have new wheels and tires installed only
by your BMW center or tire shop that
works according to BMW repair procedures

work is not carried out properly, there is a dan-
ger of subsequent damage and related safety

anced.<
Retreaded tires
BMW does not recommend that you use
retreaded tires, as driving safety may be
impaired. The causes for this include the possi-
bly different tire casing structures and the often
wide variations in their age, which can result in a
limited service life.<
The right wheels and tires
BMW recommends that you use only
wheel and tire combinations that BMW
has tested and approved for your particular
vehicle. Variations in factors such as manufac-
turing tolerances mean that even wheels and
tires with identical official size ratings could
actually have different dimensions than the
approved units – these differences could lead to
body contact, and with it the risk of severe acci-
dents. When selecting the tires, also ensure
that they have a sufficient load-carrying capac-
ity. If non-approved wheels and tires are used,
BMW cannot evaluate their suitability, and
therefore cannot be held liable for driving
safety.<
You can inquire about the right wheel/tire com-
bination at your BMW center.
The right wheel-and-tire combination is
another vital factor in ensuring reliable opera-
tion of various vehicle systems such as ABS
and DSC.
To maintain good handling and vehicle
response, use only tires of a single tread config-
uration from a single manufacturer. Following
tire damage, have the original wheel and tire
combination remounted on the vehicle as soon
as possible.
Wheels with electronics for
TPM Tire Pressure Monitor
When mounting new tires or converting from
summer to winter tires or vice versa, only use wheels with TPM electronics, otherwise the
Tire Pressure Monitor cannot detect a flat tire,
refer to page81. Your BMW center will be
happy to advise you on this subject.
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.
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

After changing wheels/tires
After changing tires or wheels, the slip detec-
tion of the Sequential Manual Transmission
must become familiar with the changed state.
Reinitialize the system for this purpose:
1.Move the selector lever into the idling
position N on a straight stretch of road at a

speed between 20 mph/30 km/h and
90 mph/150 km/h.
2.Pull both shift paddles for approx. 2 sec-
onds.
If you do not carry out initialization, the system
will automatically learn the changed state grad-
ually during driving. This may be noticeable
from the clutch opening and closing briefly.
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.
Use is only permitted in pairs, with winter tires
of the size 245/45 R 18 on the rear wheels.
Observe the manufacturer's instructions when
mounting snow chains. Do not exceed a speed
of 30 mph/50 km/h with the chains mounted.
Make sure that the snow chains are always suf-
ficiently tensioned. Retighten as needed in
accordance with the chain manufacturer's
specifications.
Do not initialize the Flat Tire Monitor after
installing snow chains as this could cause
the Flat Tire Monitor to malfunction.
After mounting or removing snow chains, the
slip detection of the Sequential Manual Trans-
mission must become familiar with the altered state. To do this, reinitialize the system, refer to
After changing wheels/tires, page190.<

Waxing
Sealant is required when water no longer beads
on the clean surface of the paint. Use only prod-
ucts that contain carnauba wax or synthetic wax
to seal your finish.
Rubber gaskets
Treat only with water or a rubber care product.
To avoid noise or damage, do not use
products that contain silicone to care for
rubber gaskets.<
Chrome components
Particularly after exposure to road salt, thor-
oughly cleanse parts like the radiator grille, door
handles, or window frames with plenty of water
with shampoo added to it. For additional treat-
ment, use chrome polish.
Alloy wheels
Depending on your system, braking can gener-
ate dust, which settles on the light-alloy wheels.
Remove this dust regularly with acid-free wheel
cleaner.
Do not use aggressive, acid-containing,
strongly alkaline, or coarse cleansers and
do not use steam cleaners at temperatures
greater than 140 °F/606, otherwise you may
damage your vehicle.<
Outside sensors
Sensors on the outside of the vehicle, such as
Park Distance Control sensors or radar sensors,
should be kept clean and free of ice to retain
their full function.
Interior care
Upholstery/fabrics
Clean regularly with a vacuum cleaner in order
to remove surface dirt.
In the event of more serious soiling such as bev-
erage stains, use a soft sponge or a lint-free
microfiber cloth in combination with suitable interior cleaners. Follow the instructions on the
packaging.
Clean upholstery material over a large
area extending out to the seams. Avoid
intense friction.<
Open Velcro fasteners on pants or other
items of clothing can cause damage to
the seat covering. Make sure that the Velcro
fasteners are closed.<
Leather/leather coverings
The leather used by BMW is a high quality
natural product. Slight patterns in the
grain are part of the typical properties of a natu-
ral leather.<
Dust and dirt from the road chafe in pores and
folds and result in considerable wear and cause
the leather surface to become prematurely brit-
tle. We therefore suggest that you clean the
leather with a dust cloth or vacuum cleaner at
regular intervals.
Particularly with light-colored leather, make
sure to clean it regularly since it has a greater
tendency to become soiled.
Treat the leather twice a year with a leather
lotion since dirt and grease harm the protective
layer of the leather.
Carpets/cargo area
Carpeting, floor mats, and luggage compart-
ment rugs and paneling can be cleaned with a
vacuum or in the event of more serious soiling,
cleansed with an interior cleaner.
Floor mats and luggage compartment rugs can
be removed for cleaning. When inserting into
place, make sure that the seat rails do not pro-
trude over the floor mats; otherwise floor mats
can be damaged.
Fluff on new floor mats is a result of the produc-
tion process and can be removed by repeated
vacuuming.
Plastic components inside
Clean the glass cover of the instrument panel,
imitation leather surfaces, lamp lenses, and
