Adding engine oilOnly add engine oil when the oil level
has dropped to just above the lower
mark on the dipstick.
Do not fill beyond the upper mark on
the dipstick. Excess oil will damage the
engine.
Before checking the engine oil level
after topping up, restart the engine and
allow it to run to obtain a correct dis-
play. Then proceed as described under
Checking the oil level.
Continuous exposure to used oil
has caused cancer in laboratory
testing. For this reason, thoroughly
wash any areas of skin that come into
contact with oil using 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.<
Recommendation: have the oil changed
at your BMW center.
Specified engine oilsThe quality of the engine oil is
extremely important for the function
and life of an engine. Based on exten-
sive testing, BMW has approved only
certain grades of engine oil.
Use only oils approved for your vehicle
model.
Ask your BMW center for details
concerning 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 infor-
mation.<
BMW engines are designed to
operate without oil additives; the
use of additives could even lead to
damage in some cases.<
Alternative oil typesIf a High Performance Synthetic Oil
approved by BMW should be unavail-
able, you may use small volumes of
other oils for topping up between oil
changes. The following data must
appear on the packaging:
>Viscosity
preferred: SAE 10W-60
alternative: SAE 5W-40 or
SAE 10W-40
>Specifications
preferred: API SJ/CF
alternative: API SJ – also SK, SL, S
etc.

Brake fluidIndicator lamp
The warning lamp comes on
even though the parking brake
is released:
The brake fluid level is too low, refer to
page 18. At the same time, there may
be significantly greater pedal travel.
Have the system checked immediately.
Warning lamp for Canadian
models.
If you continue driving, extended
pedal travel may be necessary
and braking distances may be signifi-
cantly longer. Be sure to adapt your
driving style accordingly.<
Adding brake fluidFor adding brake fluid or for determin-
ing and correcting the cause of brake
fluid loss, consult your BMW center.
Your BMW center is familiar with the
specifications for factory-approved
brake fluids – DOT 4.
Due to loss in brake fluid, pedal travel
can lengthen and braking efficiency
may be reduced.
Brake fluid is hygroscopic, that is,
it absorbs moisture from the air
over time.
In order to ensure the safety and reli-
ability of the brake system, have the
brake fluid changed every two years by
a BMW center. Refer also to the Service
and Warranty Information Booklet for
US models or the Warranty and Service
Guide Booklet for Canadian models.
Brake fluid is toxic and damages the
vehicle's paint. You should always store
it in its closed original container and in
a location inaccessible to children.
Do not spill the brake fluid and do not
fill the brake fluid reservoir beyond the
MAX mark. The brake fluid could ignite
upon contact with hot engine parts and
cause serious burns.<
Comply with the applicable envi-
ronmental laws regulating
the disposal of brake fluid.<

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.

Have your BMW center perform
maintenance and repair.
Be sure that all maintenance work is
recorded in the Service and Warranty
Information Booklet for US models, or
in the Warranty and Service Guide
Booklet for Canadian models. These
entries are your verification for the reg-
ular maintenance of your vehicle and
are required for the performance of
warranty repairs.<

Lamps and bulbsThe lamps and bulbs make essential
contributions to the safety of your vehi-
cle. Therefore, proceed carefully when
handling bulbs. BMW recommends that
you have such work performed by your
BMW center if you are not familiar with
the procedures.
Do not touch the glass portion of
a new bulb with your bare hands
since even small amounts of impurities
burn in to the surface and reduce the
service life of the bulb. Use a clean
cloth, paper napkin, or a similar mate-
rial, or hold the bulb by its metallic
base.<
A replacement bulb set is available from
your BMW center.
Before working on the electrical
system, switch off the electrical
accessory you are working on or dis-
connect the cable from the negative
terminal of the battery. Failure to
observe this precaution could result in
short circuits.
To prevent injuries and damage when
changing a bulb, be sure to comply with
any instructions provided by the bulb
manufacturer.<
Low beams and high beams>Low beams: H7 bulb, 55 watts.
>High beams: H7 bulb, 55 watts.
The H7 bulb is pressurized. There-
fore, wear safety glasses and pro-
tective gloves. Failure to comply with
this precaution could lead to injury if the
bulb is damaged.<
Please contact a BMW center in case of
a malfunction.
When cleaning the headlamps, please
follow the instructions in the Caring for
your vehicle brochure.Parking lamps5 watt bulb
Please contact a BMW center in case of
a malfunction.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 one of these bulbs should
nevertheless fail, it is possible to con-
tinue driving with great caution using
the fog lamps, provided traffic laws in
your area do not prohibit this.
Because of the extremely high
voltages involved, any work on the
xenon lighting system, including bulb-
changing, should be carried out by
technically-qualified personnel only.
Otherwise, there is a risk of fatal
injury.<

Tire repair with the M Mobility system
Precautions in case of a flat tire:
Stop the vehicle as far as possible
from passing traffic and position it on a
firm surface. Turn on the hazard warn-
ing flashers.
Turn the steering wheel to the straight-
ahead position and engage the steering
lock. Engage the parking brake and
shift into 1st or reverse gear.
All passengers should be outside the
vehicle and well away from your imme-
diate working area – behind a guardrail,
for instance.
If necessary, set up your warning trian-
gle or portable hazard warning lamp on
the roadside at an appropriate distance
from the rear of the vehicle. Comply
with all local safety guidelines and reg-
ulations.<
You will find an M Mobility system in the
BMW M3 for repairing flat tires. With
this system you can apply a sealant to
the inside of the tire, thus seal off the
damaged point, then reinflate the tire
and continue driving.
Preparing to repair a tireThe M Mobility system is located in the
luggage compartment under the floor
panel.
If possible, leave the foreign object in
the tire.
You will find corresponding
instructions for using the
M Mobility system on the device.<
Before using the M Mobility sys-
tem, read the warnings on the
sealant bottle.<
Pull the sticker showing the speed limit
from the sealant bottle and stick it onto
the steering wheel.
Please observe the expiration
date on the sealant bottle.<
