Tire treadTread depth should not be allowed to
go below 1/8 in / 3 mm, even though
European legislation, for example,
requires a mimimum tread depth of only
1/16 in / 1.6 mm. Below 1/8 in / 3 mm
tread depth, there is a great risk of
hydroplaning, even at relatively moder-
ate speeds and with only small amounts
of water on the road.
At tread depths below approx.
3/16 in / 4 mm, tire performance under
winter driving conditions deteriorates
noticeably. Worn tires should therefore
be replaced for safety considerations.
Tread wear indicators in the tread-
groove base, see arrow, are distributed
around the wheel circumference and
are labeled on the tire sidewall with
TWI, Tread Wear Indicator. At a tread
depth of 1/16 in / 1.6 mm, the indica-
tors signal that the legally permissible
wear limit has been reached.
New wheels and tires
Have new wheels and tires
mounted only by a BMW center or
specialized tire shop that works
according to BMW requirements with
appropriately trained personnel. Work
that is improperly carried out could
result in consequential damage and
pose safety hazards.<
Ask your BMW center for details con-
cerning the correct wheel and tire com-
bination. Have the wheels balanced
each time a wheel or tire has been
replaced.
The correct wheel and tire combination
also affects different systems such as
ABS or DSC. The function of these sys-
tems is impaired if improper wheel and
tire combinations are used.
BMW advises against using
retreaded tires, as driving safety
could otherwise be impaired. The rea-
son for this are the possibly different
tire casing structures involved, some of
which may be greatly aged, factors
which can lead to a decrease in durabil-
ity.<
Tire condition

The correct wheels and tires
BMW recommends using only
wheels and tires that have been
tested and approved by BMW for the
particular vehicle model, as otherwise
body contact and serious accidents can
result despite the use of the same nom-
inal size, e.g. due to manufacturing tol-
erances. If non-approved wheels and
tires are used, BMW cannot evaluate
their suitability, and therefore cannot be
held liable for driving safety.<
To maintain good handling and vehicle
response, use only tires of a single
brand and tread configuration. After a
flat tire, have the previous wheel and
tire combination restored as soon as
possible.
Recommended tire sizes and
brandsFor each tire size, certain tire brands
have been tested, classified as road-
safe and approved by BMW. You can
find out about these from a professional
tire center, preferably your BMW cen-
ter. Observe any country-specific regu-
lations, e.g. on making a corresponding
entry in the vehicle documents.
The factory-approved radial belt tires
are matched to your vehicle and pro-
vide optimum safety and driving com-
fort when used properly.Special characteristics of winter
tiresBMW recommends the use of winter
tires for operation under winter road
conditions. While all-season tires with
M+S designation provide better winter
traction than summer tires, they gener-
ally do not achieve the full performance
of winter tires.Observing speed ratings
Never exceed the maximum
speed for which the winter tires
are rated. Unprofessional attempts by
laymen to service tires can lead to dam-
age and accidents. Have this work per-
formed by skilled professionals only.
The technicians at your BMW center
will be glad to assist you with the
required professional knowledge and
specialized equipment.<
StorageAlways store tires in a cool, dry place.
Store them away from light whenever
possible. Protect the tires against con-
tact with oil, grease and fuel. Do not
exceed the maximum tire inflation pres-
sures specified on the tire sidewall.

126Maintenance
BMW Maintenance SystemThe BMW Maintenance System helps
maintain your vehicle's road safety and
operational safety. Comfort-related
aspects, such as the timely change of
filters for the air inside the vehicle, are
taken into consideration. The goal is to
optimize maintenance with respect to
low total cost of ownership.
If you should sell your BMW one day,
consistent service and maintenance will
prove to your advantage.
Service interval displayThe service interval display shows you
when an oil service, an inspection –
always alternating between I and II – or
a brake fluid change is due. The special
feature is that the service intervals are
calculated according to your BMW's
individual driving conditions instead of
from fixed mileage increments.
The technology developed for this
takes your personal driving style into
account, as well as your BMW's driving
conditions. After all, short-distance
driving, i.e. frequent cold starts, or driv-
ing off at high engine speeds, affects
your BMW differently from long-dis-
tance driving with the engine at consis-
tent operating temperature.
Have a break-in inspection per-
formed at approx. 1,250 miles/
2,000 km regardless of the service
interval indicated on the display.<
Special feature regarding engine
oil changeThe calculation of the service intervals
covers practically every kind of operat-
ing situation. If you drive very rarely,
however, you should have the oil
changed at least every two years, since
engine oil deteriorates over time
regardless of use.Service and Warranty Information
Booklet for US models/Warranty
and Service Guide Booklet for
Canadian modelsFor additional information on required
maintenance intervals and procedures,
please refer to the Service and War-
ranty Information Booklet for US mod-
els, or the Warranty and Service Guide
Booklet for Canadian models.
As a precaution against corrosion, it is
advisable to have the body checked for
damage from rocks or gravel at the
same time, depending upon operating
conditions.

4. Adjust the tire inflation pressure to
29 psi / 200 kilopascal. For this pur-
pose, with the ignition key in
position 2:
>Increase the tire pressure: switch
on the compressor, position I. To
check the current inflation pres-
sure, turn off the device briefly
>Reduce the tire pressure: press
button 8, or turn screw 8 on the
manometer.
Do not run the compressor for
longer than 10 minutes, otherwise
the unit may overheat and be dam-
aged.<
If the tire fails to hold the pres-
sure, drive the vehicle again, see
Distributing the sealant. Then repeat
Steps 1 through 4 once.
The use of the M Mobility system may
be ineffective if the damaged area in
the tire is larger than approx. 1/8 in /
4 mm. If the tire cannot be temporarily
repaired with the M Mobility system,
please consult the nearest BMW cen-
ter, or a workshop that has appropri-
ately trained personnel working in
accordance with BMW specifications,<
The tire pressure must be at least
29 psi / 200 kilopascal. Otherwise,
do not continue driving.<
Driving on
Do not exceed the maximum
speed limit of 45 mph / 80 km/h;
otherwise, accidents may occur.<
Have the damaged tire replaced
as soon as possible. Reinitialize
the Flat Tire Monitor, and refer to
page 84 for further information.
Have the sealant bottle of the M Mobil-
ity system replaced.<
Battery
Battery posts, terminals, and
related accessories contain lead
and lead compounds. Wash hands after
handling.<
MaintenanceThe battery is completely maintenance-
free. This means that the original bat-
tery acid will normally last for the ser-
vice life of the battery under moderate
climate conditions. Your BMW center
will be glad to advise you if you have
any questions concerning the battery.
Please consult your BMW center
whenever you have any questions
concerning the battery. when the engine is not running. Use the
connections provided in the engine
compartment. Terminals, refer to Jump-
starting, page 143.
