Run-Flat Tires
When mounting new tires or changing over
from summer to winter tires and vice versa,
mount Run-Flat Tires for your own safety. In the
event of a flat, moreover, no spare wheel is
available. Your BMW Center will be glad to
advise you.
For safety reasons, BMW recommends
that damaged Run-Flat Tires be replaced
rather than repaired.<
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
Always comply with the speed limit for the
winter tires mounted on your car; failure
to do so could result in tire damage and acci-
dents.<
If the car is capable of speeds higher than that
permitted for the winter tires, a label stating the
maximum permitted speed for the mounted
tires must be displayed in your field of view.
Specialist tire dealers and your BMW Center
can supply these labels.
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 sidewall
of the tire.
Snow chains*
Only certain fine-link snow chains have been
tested by BMW, classified as safe for use and
recommended. Consult your BMW Center for
more information. Attach snow chains in pairs
and only to the rear wheels. Observe the manu-facturer's instructions when mounting snow
chains. Do not exceed a speed of 30 mph or
50 km/h.
You are not permitted to mount snow chains to
tires of the following sizes:
>255/40 R 17
>255/35 R 18
>255/30 R 19
Do not initialize the Flat Tire Monitor if
snow chains are mounted, otherwise the
instrument might issue an incorrect reading.
When driving with snow chains, you may find it
helpful to activate DTC temporarily, refer to
page66.<

Engine oil
The engine oil consumption is dependent on
driving style and driving conditions.
Checking oil level
Your car is equipped with an electronic oil-level
monitor.
For a precise measurement and display of the
oil level, it is necessary that the engine be at
operating temperature, e.g. after uninterrupted
driving for at least approx. 6.5 miles/10 km. You
can have the oil level displayed while you are
driving, or while the vehicle is at a standstill on a
level surface and the engine is running.
You can have the oil level reading displayed in
the instrument cluster.1.Lightly push button 1 in the turn indicator
stalk up or down repeatedly until the appro-
priate symbol is shown in the display,
accompanied by the word "OIL".
2.Press button 2 in the turn indicator stalk.
The oil level is checked and the reading dis-
played.

Possible displays
1Oil level OK
2Oil level is being checked.
This can take about 3 minutes if the car is at
a standstill on a level surface, or about
5 minutes while the car is on the move.
3Oil level down to minimum:
Add 1 US quart/1 liter of engine oil as soon
as possible, refer also to Adding engine oil.
4Oil level is too high.
Too much oil will harm the engine.
Have the vehicle checked without
delay.<
5The oil level sensor is defective.
Do not add engine oil. You can continue
your journey. Note the newly calculated dis-
tance remaining to the next oil service, refer
to page117. Have the system checked as
soon as possible.
Adding engine oil
Do not add the maximum amount of 1 US quart/
1 liter of engine oil until the following warning
lamp lights up in the instrument cluster, or in
cars with gasoline engines until the oil level
monitor shows "+1qts" or "+1l".
Add oil within the next 125 miles/200 km,
otherwise the engine could be dam-
aged.<
Keep oils, greases, etc. out of the reach of
children and comply with the warnings on
the containers. Otherwise, health hazards may
result.<
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.
Only use approved BMW High Performance
Synthetic Oil.

If BMW High Performance Synthetic Oil is not
available, you can add small quantities of other
synthetic oils in between oil changes. Only use
oils with the API SH specification or higher.
Your BMW Center will be glad to answer
any questions regarding BMW High Per-
formance Synthetic Oil or approved synthetic
oils.<
You can also call BMW of North America at
1-800-831-1117 or visit the website
www.bmwusa.com to obtain this information.
Viscosity ratings
Viscosity is a measure of an oil's flow rating and
is categorized in SAE classes.
Selecting the appropriate SAE class depends
on the regional climatic conditions in which you
normally drive your BMW.
Approved oils belong to the 5W-40 and
5W-30 classes.<
These oils can be used for driving at all outside
temperatures.
Coolant
Do not add coolant to the cooling system
when the engine is hot. Escaping coolant
can cause burns.<
Coolant is a mixture of water and an additive.
Not all commercially available additives are suit-
able for your BMW. Ask your BMW Center for
suitable additives.
Only use suitable additives, otherwise
engine damage may result. The additives
are hazardous to your health.<
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 a little
counterclockwise to allow any accumulated pressure to escape, then continue turning
to open.
3.The coolant level is correct if it is between
the maximum and minimum marks in the
filler neck, refer also to the diagram next to
the filler neck.
4.If the coolant is low, slowly add coolant up to
the specified level; do not overfill.
5.Turn the cap until there is an audible click.
6.Have the reason for the coolant loss elimi-
nated as soon as possible.
Brake system
Malfunctions
Brake fluid
The warning lamps light up in red
even though the handbrake has been
released. Stop immediately.
The brake fluid in the reservoir has fallen to
below the minimum level. At the same time, a
considerably longer brake pedal travel may be
noticeable. Have the system checked without
delay.
Display of this malfunction on Cana-
dian models.
If you continue to drive the car, you may
have to depress the brake more and brak-
ing distances may be significantly longer.
Please adapt your driving style accordingly.<

Under the hood

Brake pads
The warning lamps light up in red
even though the handbrake has been
released. The brake pads have
reached the safe limit for pad wear.
Have brake pads replaced immediately.
Display of this malfunction on Cana-
dian models.
For your own safety: use only brake pads
that BMW has approved for the corre-
sponding vehicle model. BMW is unable to
assess the suitability of brake pads it has not
approved and therefore cannot guarantee their
safety.<

Maintenance

Socket for On-Board
Diagnosis OBD
Primary components that make up exhaust
emissions can be checked by a device via the
OBD socket.
This socket is located on the driver's side to the
left, on the bottom of the instrument panel
underneath a cover.
Exhaust emission values
The warning lamps come on. The
exhaust emission values have wors-
ened. Have the car checked as soon
as possible.
Canadian models display these warn-
ing lamps.
The lamps flash under certain condi-
tions. This indicates excessive misfiring in the
engine. If this happens, you should reduce your
speed and visit your nearest BMW Center as
soon as possible. Severe engine misfiring can
quickly lead to serious damage of emissions-
related components, especially the catalytic
converter.
If the gas cap is not properly tightened, the OBD
system will assume that fuel vapor is escaping.
An indicator will then light up. If the gas cap is
then tightened, the indicator will go out within a
few days.
Event data recorders
Your vehicle may be equipped with one or sev-
eral measuring or diagnostic modules or a
device for recording or sending certain vehicle data or information. In addition, if you have
signed a subscription contract for BMW Assist,
certain vehicle data may be transmitted or
recorded in order to facilitate the corresponding
services.
Care
Important information on the care and mainte-
nance of your BMW is contained in the Caring
for your vehicle brochure.

Replacing components
120 any instructions provided by the bulb manufac-
turer.<
For care and maintenance of the headlamps,
please follow the instructions in the separate
Caring for your vehicle brochure.
If the routine for changing a particular
bulb is not described here, please contact
your BMW Center or a workshop that works
according to BMW repair procedures with cor-
respondingly trained personnel.<
Light-emitting diodes LEDs
Light-emitting diodes installed behind translu-
cent lenses serve as the light source for many of
the controls and displays in your vehicle. These
light-emitting diodes, which operate using a
concept similar to that applied in conventional
lasers, are officially designated as Class 1 light-
emitting diodes.
Do not remove the covers or expose the
eyes directly to the unfiltered light source
for several hours at a time, otherwise this could
cause irritation to the retina.<
Xenon lamps*
The service life of these bulbs is very long and
the probability of a failure is very low, provided
that they are not switched on and off an unusual
number of times. If a xenon lamp fails neverthe-
less, switch on the fog lamps and continue the
journey with great care, provided that local leg-
islation does not prohibit this.
Have work on the xenon lighting system
performed only by your BMW Center or a
workshop that works according to BMW repair
procedures with correspondingly trained per-
sonnel. Due to the high electrical voltages
present, there is a risk of potentially fatal acci-
dents if work is performed inappropriate.<
Parking lamps, roadside parking lamps
In the event of a malfunction, please contact
your BMW Center or a workshop that works
according to BMW repair procedures with cor-
respondingly trained personnel.
Halogen lamps
H7 bulb, 55 watts
Always wear gloves and eye protection;
the atmosphere within the H7 bulb is
pressurized. Otherwise there is a risk of injury if
the bulb is damaged.<
There are separate headlamp covers for low-
beam headlamps and high-beam headlamps.
Be careful when installing the covers, oth-
erwise leaks could occur and cause dam-
age to the headlamp system.<
For checking and adjusting headlamp
aim, please contact your BMW Center.<
Access to the lamps
The high-beam headlamp can be accessed
from the engine compartment, whereas the
low-beam headlamp is accessed through a flap
