Wheel and tire combinationsThe right choice
BMW recommends using only
wheels and tires that have been
approved by BMW for use on your par-
ticular model. Although other wheels
and tires may theoretically have the
same dimensions, variations in factors
such as manufacturing tolerances can
result in contact between tire and body-
work, ultimately leading to serious acci-
dents. BMW cannot evaluate all tires
and wheels on the market, and is thus
unable to guarantee that the vehicle will
continue to perform safely if unap-
proved tires and/or wheels are
mounted.<
For each tire size, BMW has assessed
the safe performance of specific tire
brands and approved them for use.
Consult any BMW center for details.
Comply with any local/national regula-
tions, for example by recording the tire
type in the vehicle documents.
The correct wheel and tire combi-
nation affects various systems
that would otherwise be impaired, for
example ABS, DSC and ADB-X/DBC.
For this reason, use only tires of the
same manufacture and tread configura-
tion. In the event of a flat tire, for exam-
ple, remount the approved wheel and
tire combination as soon as possible.<
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 infla-
tion pressures specified on the tire
sidewall.
Winter tiresChoosing the right tireBMW 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 the corresponding sum-
mer tires, they generally do not achieve
the performance of winter tires.
In the interest of safe tracking and
steering response, install winter tires
made by the same manufacturer and
having the same tread configuration on
all four wheels.
Never exceed the maximum
speed for which the winter tires
are rated.
Unprofessional attempts by laymen to
service tires can lead to damage and
accidents.
Have this work performed by trained
professionals only. Any BMW center
has the required technical knowledge
and the proper equipment and will be
happy to assist you. your BMW is eqipped with Run Flat
tires. These are indicated by a circular
symbol containing the letters RSC on

Adding engine oilOnly add engine oil when the oil level
has dropped to just above the lower
mark on the dipstick.
BMW engines are designed to
operate without oil additives; the
use of additives could lead to damage
in some cases. This also applies to the
manual transmission, the automatic
transmission, the differential, and the
power steering system.<
Recommendation: have the oil changed
at your BMW center.
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 oils, grease and similar materials
so that they are inaccessible to chil-
dren. Comply with warning labels and
information on containers.<
Comply with the applicable envi-
ronmental laws regulating the dis-
posal of used oil.<
Specified engine oilsThe quality of the engine oil is
extremely important for the operation
and service life of an engine. Based on
extensive testing, BMW has approved
only certain grades of engine oil.
Use only approved BMW High Perfor-
mance Synthetic Oil.
If an approved BMW High Performance
Synthetic Oil should be unavailable, you
may use small volumes of other syn-
thetic oils for topping up between oil
changes. Use only oils with the specifi-
cation API SH or higher.
Ask your BMW center for details
concerning the specific BMW
High Performance Synthetic Oil or syn-
thetic oils that have been approved.<
You can also call BMW of North
America toll-free at 1-800-831-1117 or
visit this website: www.bmwusa.com to
obtain this information.
Viscosity ratingsViscosity is the oilflow rating as estab-
lished in SAE classes.
The selection of the correct SAE class
depends on the climatic conditions in
the area where you drive your BMW.
Approved oils are in SAE classes
5W-40 and 5W-30.<
These kinds of oil may be used for driv-
ing in all ambient temperatures.

Changing a wheel
Safety precautions in the event of
a flat tire or wheel change:
Stop the vehicle as far as possible from
passing traffic. Park on a firm, flat, sur-
face. Switch on the hazard warning
flashers. Turn the steering wheel to the
straight-ahead position and engage the
steering lock. Shift into 1st or Reverse,
or if you have an automatic transmis-
sion position the selector lever in Park,
and engage the parking brake.
All passengers should be outside the
vehicle and well away from your imme-
diate working area, behind a guardrail,
for example.
If a warning triangle or portable hazard
warning lamp is available, set it up on
the roadside at an appropriate distance
from the rear of the vehicle. Comply
with all safety guidelines and regula-
tions.
Change the wheel only on a level, firm
surface which is not slippery. Avoid
jacking the vehicle on a soft or slippery
support surface – snow, ice, loose
gravel, etc. – as either the vehicle or the
jack could slip sideways.
Position the jack on a firm support sur-
face.
Do not place wooden blocks or similar
objects under the jack. They could pre-
vent the jack from extending to its full
height and reduce its support capacity.
Do not lie under the vehicle or start the
engine when the vehicle is supported
by the jack. There is otherwise a risk of
fatal injury.<
Your BMW is equipped with a spare tire
or a space-saver spare tire designed for
temporary use in maintaining the vehi-
cle's mobility in an emergency.
To remove the spare tire, lift the
floor panel in the luggage com-
partment completely out, refer to
page 40.<

Do not attempt to install the full
wheel cover on the space-saver
spare tire, since this could damage the
cover.<
The vehicle jack is designed for
changing wheels only. Do not
attempt to raise another vehicle model
with it or to raise any other type of load.
To do so could cause accidents and
personal injury.
To ensure continued safety, have the
tightness of the torque bolts checked
with a calibrated lug wrench – torque
specification: 88.5 lb ft/120 Nm – at the
earliest opportunity.<
When storing a wheel in the spare tire
recess, take care to avoid bending the
threaded rod.
If light-alloy wheels other than original
BMW light-alloy wheels have been
mounted, it may be necessary to use
different lug bolts for those wheels.
Replace the defective tire as soon as
possible and have the new wheel/tire
balanced.
Driving with the space-saver
spare tireDrive cautiously. Do not exceed a
speed of 50 mph / 80 km/h.
Be aware that vehicle handling may be
altered. Anticipate, e.g., reduced track-
ing during braking, longer braking dis-
tances, and changed steering charac-
teristics when approaching limit
conditions. These handling characteris-
tics will be even more pronounced if
winter tires are mounted.
Only one space-saver spare tire
may be mounted at one time.
Mount a wheel and tire of the original
size at the earliest possible opportu-
nity. For certain wheel/tire combina-
tions, the size of the spare tire will
differ from that of the remaining tires.
The spare tire is fully functional at all
loads and speeds. However, the spare
tire should be replaced at the earliest
possible opportunity in order to achieve
the original operating conditions.<
Run Flat tires*Run Flat tires are labeled on the side-
wall with a circular symbol containing
the letters RSC. Run Flat tires consist of
self-supporting tires and special rims.
The tire reinforcement ensures that
driving remains possible to a restricted
degree in the event of pressure drop or
even if the tire is deflated.
When mounting or replacing sum-
mer tires with winter tires, or vice
versa, use Run Flat tires since no spare
wheel is available in the event of a flat.
In this event, BMW recommends con-
sulting your BMW center. Your BMW
center has the information needed for
working with Run Flat tires and is
equipped with the necessary special
tools.<

Driving with a damaged tireDepending on the cargo load, Run Flat
tires allow you to continue driving at a
maximum speed of 50 mph / 80 km/h. If
there is a total loss of tire inflation pres-
sure, 0 psi/0 kPa, or obvious tire dam-
age, you can determine the distance
you may continue driving based on the
following values:
>With a light load:
1 to 2 persons without luggage:
approx. 150 miles/250 km
>With a medium load:
2 persons, luggage compartment full;
or 5 persons without luggage:
approx. 100 miles/150 km
>With a full load:
5 persons, luggage compartment full:
approx. 30 miles/50 km.
Drive cautiously. Do not exceed a
speed of 50 mph / 80 km/h. Be
aware that vehicle handling will be
altered when there is a loss in inflation
pressure. Anticipate, e.g., reduced
tracking during braking, longer braking
distances and changed steering char-
acteristics.
For safety reasons, BMW recommends
not having damaged Run Flat tires
repaired. In this case, consult your
BMW center.<
BatteryMaintenanceThe battery is maintenance-free, that is,
the original electrolyte will normally last
for the service life of the battery under
moderate climatic conditions.
Please consult your BMW center
whenever you have any questions
concerning the battery. cle, leave the engine off at all times.
Connect the charge cables to the termi-
nals in the engine compartment. For
terminal locations, refer to Jump-start-
ing on page 153.Disposal
Return used batteries to a recy-
cling point or your BMW center.
Maintain the battery in an upright posi-
tion for transport and storage. Secure
the battery against tilting during trans-
port.<
FusesYou will find the fuses and information
on their respective allocation in the
glove compartment behind a panel with
two snap clips.
Do not attempt to repair a blown
fuse or replace it with a fuse
having a different color or amperage
rating. To do this could cause a fire in
the vehicle resulting from a circuit over-
load.<
