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: at least twice a
month and before starting long trips. Other-
wise, 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
page86, or reset the Tire Pressure Monitor,
refer to page87.<
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
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.
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.<
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 For instance

Run-flat tires
You will recognize run-flat tires by the circular
symbol containing the letters RSC on the side
of the tire.
Run-flat tires consist of partially self-contained
tires and special rims. The sidewall reinforce-
ment ensures that the tire retains some residual
safety in the event of pressure drop and driving
remains possible to a restricted degree.
To continue driving with a damaged tire:
>With Flat Tire Monitor, refer to Indication of
a flat tire, page86
>With Tire Pressure Monitor, refer to Notifi-
cation of low tire inflation pressure, page88
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
with correspondingly trained personnel. If this
work is not carried out properly, there is a dan-
ger of subsequent damage and related safety
h a z a r d s . M a k e s u re t h a t t h e n e w w h ee l s a r e b a l-
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. 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 page87. Your BMW center will be
happy to advise you on this subject.

Under the hood
Never attempt to perform any service or
repair operations on your vehicle without
the required professional technical training.
If you do not know what repair procedures to
follow, have work on your vehicle done only by
your BMW center or a workshop that works
according to BMW repair procedures with cor-
respondingly trained personnel. If this work is
not carried out properly, there is a danger of
subsequent damage and related safety haz-
ards.<

204 >"Measuring engine oil level...":
This can take about 3 minutes if the car is at
a standstill on a level surface and the engine
is running, and about 5 minutes while the
car is moving.
If the engine oil has been topped off, the
measurement of the oil level can take up to
30 minutes.
>"Engine oil level below minimum. Add 1
quart!":
Add a maximum of 1 US quart/1 liter of
engine oil at the next opportunity, refer also
to Adding engine oil below. If the oil level
displayed is below minimum, add engine oil
immediately. Failure to do so may lead to
engine damage.
>"Engine oil level too high! Have this
checked.":
Too much oil will harm the engine.
Have the vehicle checked without
delay.<
>"Measurement inactive. Have this
checked.":
Do not add engine oil. You can continue
your journey. Note the newly calculated dis-
tance remaining to the next oil service, refer
to Service requirements on page75. Have
the system checked as soon as possible.
Adding engine oil
Do not add 1 US quart/liter of oil until a corre-
sponding message is shown on the Control Dis-
play.
Add oil within the next 125 miles/200 km,
otherwise the engine could be dam-
aged. caused cancer in laboratory testing.
For this reason, thoroughly wash exposed areas
of skin with soap and water after such work.
Keep oil, grease etc. out of reach of children and
observe the warnings on the containers to pre-
vent health risks.<
Oil change
Have oil changed only at your BMW center or
at a workshop that works according to BMW
repair procedures with correspondingly trained
personnel.
Approved engine oils
The quality of the engine oil selected has critical
significance for the operation and service life of
an engine. BMW continuously approves spe-
cific oils after confirming their suitability for use
in its vehicles with extensive testing.
Only use approved BMW High Performance
Synthetic Oil.
If BMW High Performance Synthetic Oil is
unavailable, you can add small quantities of
other synthetic oils between oil changes. Only
use oils of the specification API SM or higher.
Your BMW center will be happy to answer
detailed questions on BMW High Perfor-
mance Synthetic Oil or approved synthetic
oils.<
You can also call BMW of North America at 1-
800-831-1117 or visit the website at
www.bmwusa.com to obtain this information.
Do not use oil additives; under some cir-
cumstances, they can damage your
engine.<
Viscosity grades
Viscosity is a measure of an oil's flow rating and
is specified in SAE grades.
The choice of the right SAE grade is based on
the climatic conditions in the region in which
you normally drive your BMW.
Approved oils belong to the 0W-40,
0W-30, 5W-40 and 5W-30 SAE grades.<

Maintenance
BMW maintenance system
The BMW maintenance system supports the
preservation of the traffic and operating safety
of your BMW. The service schedule also
includes operations related to the vehicle's
comfort and convenience features, such as
replacement of the filters for the inside air.
The ultimate objective is to ensure economical
maintenance by providing the ideal service for
your vehicle.
Should the day come when you decide to sell
your BMW, a complete center service history
will prove to be an asset of inestimable value.
CBS Condition Based Service
Sensors and special algorithms take the differ-
ent driving conditions of your BMW into
account. Condition Based Service uses this to
determine the current and future service
requirements. By letting you define a service
and maintenance regimen that reflects your
own individual requirements, the system builds
the basis for trouble-free driving.
You can set the Control Display to show
remaining distances and times of selected
maintenance intervals and legally mandated
deadlines, refer to page75:
>Engine oil
>Brake pads, front and rear separately
>Brake fluid>Vehicle check
>Legally mandated inspections depending
on local regulations
Service data in remote control
Your vehicle stores the information required
maintenance continuously in the remote con-
trol during driving. After accessing the data
stored in the remote control, your BMW Service
Advisor can suggest precisely the right array of
service procedures for your own individual vehi-
cle. You should therefore hand over the remote
control you last used to drive to the BMW Ser-
vice Advisor when you take your vehicle in for
service.
Make sure the date is set correctly, refer
to page77, otherwise the effectiveness
of CBS Condition Based Service is not
ensured.<
