Wheels and tires
Tire inflation pressure
Information for your safety
It is not merely the tire's service life, but also
driving comfort and – to a great extent – driving
safety that depend on the condition of the tires
and the maintenance of the specified tire pres-
sure.
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 deflated, i.e. flat tires,
except run-flat tires. A flat tire will seriously
impair your vehicle's handling and braking
response. Attempts to drive on a flat tire can
lead to loss of control over the vehicle.<
After correcting the inflation pressure(s),
always reinitialize the Flat Tire Monitor,
refer to page80.<
Pressure specifications for factory-
installed tires
The inflation pressures for your standard tires at
ambient temperature can be found on the door
post when you open the driver's door.
Pressure specifications for other tire
sizes
The tables below provide all the correct inflation
pressures for the specified tire sizes at ambient
temperature.
For correct identification of the right tire
inflation pressure for your tires, observe
the specifications for the corresponding tire
size.<
Tire size
The inflation pressures apply to the tire sizes
approved and tire brands recommended by
BMW; a list of these is available from your BMW
center.

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 correct combination of wheels and tires 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. After a flat
tire, have the original wheel and tire combina-
tion remounted on the vehicle as soon as possi-
ble.
Recommended tire brands
BMW tests certain tire brands for each tire size,
classifies them as road-safe and approves
them. Consult your BMW center for more infor-
mation.
Observe any country-specific regulations, e.g.
on making a corresponding entry in the vehicle
documents.
The factory-mounted tires have been specially
selected to provide optimized performance
when installed on yo ur vehicle; if pro perly cared
for, they will provide a combination of safety and
excellent ride comfort.
Run-flat tires
When mounting new tires or changing from
summer tires to winter tires or vice versa, use
run-flat tires because there is no spare tire in
case of a flat. Your BMW center will be glad to
advise you.
For safety reasons, BMW recommends
that you do not have damaged run-flat
tires repaired; they should be replaced.<
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.
Pay attention to speed
Do not exceed the maximum permissible
speed for the winter tires, otherwise tire
damage may occur, which can result in acci-
dents.<
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 side wall
of the tire.
Snow chains*
BMW only tests certain fine-link snow chains,
classifies them as road-safe and approves
them. Consult your BMW center for more infor-
mation. BMW recommends using these
approved, fine-link snow chains.
Use is only permitted in pairs, with winter tires
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.
After snow chains are mounted, do not
initialize the Flat Tire Monitor.
When driving with snow chains, it can be useful
to activate the DTC temporarily, refer to
page78.<

Under the hood
178 Do not exceed the upper marking on the
dipstick, otherwise an overfilling of oil can
damage the engine.<
Adding engine oil
Do not top off the oil until the oil level has
dropped to just above the lower marking on the
dipstick. In this area a message also appears on
the Control Display.
Refill the oil within the next 125 miles/
200 km, otherwise engine damage could
result.<
Continuous exposure to used oil has
caused cancer in laboratory testing.
For this reason, any skin areas that come into
contact with oil should be thoroughly washed
with soap and water.
Store oil, grease, etc., well out of the reach of
children; always observe all warning labels on
the containers.<
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.
Specified 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.
Use only approved BMW High Performance
Synthetic Oil.
If you are unable to obtain BMW High Perfor-
mance Synthetic Oil, you can add small amounts of another synthetic oil between oil
changes. Use only oils with the API SH specifi-
cation or higher.
Ask your BMW center for details concern-
ing the specific BMW High Performance
Synthetic Oil or synthetic oils which have been
approved.<
You can also call BMW of North America at
1-800-831-1117 or visit this website:
www.bmwusa.com to obtain this information.
Viscosity ratings
Viscosity is the oil flow rating as defined in
SAE classes.
The selection of the correct SAE class depends
on the climatic conditions in the area where you
typically drive your BMW.
Approved oils are in SAE classes 5W-40
and 5W-30.<
These oils may be used for driving in all ambient
temperatures.
Coolant
Do not add coolant to the cooling system
when the engine is hot. Escaping coolant
can cause burns.<
Coolant consists of water and the addition of
antifreeze and anticorrosion agent. Not all com-
mercially available additives are suitable for
your BMW. Ask your BMW center for suitable
additives.
Only use suitable additives, as otherwise
engine damage may result. The additives
present a health hazard; observe the instruc-
tions on the containers.<
Comply with the appropriate environ-
mental protection regulations when dis-
posing of coolant additives.<
Checking coolant level
1.The engine must be at ambient tempera-
ture.
2.Turn the cap of the expansion tank counter-
clockwise to allow any accumulated pres-

Maintenance
The 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, you will find that a complete dealer
service history is 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 times or distances of selected main-
tenance intervals and legally mandated dead-
lines, refer to page66:
>Engine oil
>Brakes, front and rear separately
>Microfilter/activated-charcoal filter
>Brake fluid>Spark plugs
>Vehicle check
>Legally mandated inspections depending
on local regulations
Your vehicle stores this information continu-
ously in the master key while the vehicle is
being driven. After accessing the data stored in
the master key, your BMW Service Advisor can
suggest precisely the right array of service pro-
cedures for your own individual vehicle. You
should therefore hand over to the BMW Service
Advisor the key you last used to drive when you
take your vehicle in for service.
Make sure the date in the Control Center
is always set correctly, refer to page74,
as otherwise the effectiveness of CBS Condi-
tion Based Service is not ensured.<
