To releasePull the lever located under the left-
hand side of the instrument panel.
Do not attempt to service your
vehicle if you do not have the
required technical background. Failure
to work in an informed, professional
manner when servicing components
and materials constitutes a safety
hazard for vehicle occupants and other
road users. If you are not familiar with
the guidelines, please have the opera-
tions performed by your BMW center.<
To openPull the release handle and open the
hood.
To closeAllow the hood to fall from a height of
about 12 in (30 cm) so that it audibly
engages.
To avoid injuries, be sure that the
travel path of the hood is clear
when it is closed, observing the same
precautions as with all closing proce-
dures.
If you determine that the hood is not
completely closed while driving, stop
immediately and close it securely.<

Engine oil
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.
Always store oil, grease, etc., out of
reach of children. Comply with all
warning labels and information on
containers.<
Comply with the applicable envi-
ronmental laws regulating the
disposal of used oil.<
Specified engine oilsThe quality of the engine oil is
extremely important for the function
and service life of an engine. Based on
extensive testing, BMW has approved
only certain grades of engine oil.
Use only approved "BMW High
Performance Synthetic Oil".
If you are unable to obtain an approved
"BMW High Performance Synthetic
Oil", you may use small volumes of
other synthetic oils for topping up
between oil changes. Use only oils with
the specification API SH or higher.
Ask your BMW center for details
concerning the specific "BMW
High Performance Synthetic Oil" or
synthetic oils that 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 oilflow rating as estab-
lished in SAE classes.
The selection of the correct SAE class
depends on the climatic conditions in
the area you drive your BMW.
Approved oils are in SAE classes
5W-40 and 5W-30.<
These kinds of oil may be used for
driving in all ambient temperatures.

Brake fluidIndicator lamp
The brake warning lamp comes
on when the parking brake is
not engaged: the brake fluid
level is too low, refer to page 17.
Brake warning lamp for Cana-
dian models.
Adding brake fluidFor adding brake fluid or for deter-
mining 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).
Brake fluid loss results in extended
brake pedal travel. Refer to the informa-
tion on page 106.
Brake fluid is hygroscopic, that is,
it absorbs moisture from the air
over time.
In order to ensure the brake system's
safety and reliability, have the brake
fluid changed every two years by a
BMW center, refer to page 66 or to the
Service and Warranty Information
Booklet (US models) or the Warranty
and Service Guide Booklet (Canadian
models).
Brake fluid is toxic and damages the
vehicle's paint. You should always store
it in its original container and in a loca-
tion which is out of reach of children.
Do not spill the 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.<

OverviewControlsMaintenanceRepairsDataIndex
The BMW Maintenance System has
been designed as a reliable means of
providing maximum driving and oper-
ating safety Ð and as cost-effectively as
possible for you.
Please keep in mind that regular main-
tenance is not only necessary for the
safety of your vehicle, but also plays a
significant role in maintaining the resale
value of the vehicle.
Service Interval DisplayWhile conventional systems rely on
distance traveled alone to determine
when service is due, the BMW Mainte-
nance System has for years considered
the actual conditions under which the
vehicle operates, because miles can be
traveled in many different ways:
From a maintenance point of view,
62,000 miles (100,000 km) of short-
distance urban driving cannot be
compared with 62,000 miles
(100,000km) of long-distance highway
travel.
The BMW Maintenance System
includes the Engine Oil Service and
Inspections I and II.
Determining the maintenance intervals
according to the actual use of the
vehicle covers every kind of operating
situation. However, drivers who cover
only extremely short distances Ð
substantially less than 6,200 miles
(10,000 km) annually Ð should still have
the engine oil changed at least every
2 years, as it continues to age regard-
less of whether the vehicle is used on a
regular basis.
Service and Warranty Information
Booklet (US models)/Warranty
and Service Guide Booklet (Cana-
dian models)For additional information on required
maintenance intervals and procedures,
please refer to the Service and
Warranty Information Booklet (US
models), or the Warranty and Service
Guide Booklet (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.
We recommend that you refer all
maintenance and repair opera-
tions to your BMW center.
Be sure that all maintenance work is
confirmed in the Service and Warranty
Information Booklet (US models), or in
the Warranty and Service Guide
Booklet (Canadian models). These
entries confirm that your vehicle has
benefitted from regular maintenance,
and are also required for warranty
claims.<

OBD interface socket
The interface socket for onboard diag-
nostics is located on the left-hand side
of the driver's side, on the underside of
the instrument panel and under a cover
panel. The cover has the letters OBD on
it.
This interface makes it possible to
access data on emissions-related
components using special equipment.
An illuminated indicator informs
you of the need for service, not
that you need to stop the
vehicle. Your system should be
checked, however, at the earliest
opportunity.
If the indicator blinks or flashes, this
indicates a high level of engine misfire.
Reduce speed and contact the nearest
BMW center immediately. Severe
engine misfiring over even a short
period of time can seriously damage
emission control system components,
especially the catalytic converter.
SERVICE ENGINE SOON

enough, the OBD system can
detect leaking vapor and the indicator
will light up. If the fuel filler cap is then
tightened, the indicator will usually go
out after a short period of time. <

Lamps and bulbsThe lamps and bulbs make essential
contributions to the safety of your
vehicle. Therefore, comply fully with the
following instructions during bulb
replacement. If you are not familiar with
any of the procedures, consult your
BMW center.
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
disconnect the cable from the negative
terminal of the battery. Failure to
observe this precaution could result in
short circuits.
To prevent injuries and damage,
comply with any instructions provided
by the bulb manufacturer.<
Low and high beamsEngine compartment, left side:
1 Low beams
2 High beams
H7 bulb, 55 watts
The H7 bulb is pressurized. There-
fore, wear safety glasses and
protective gloves. Failure to comply
with this precaution could lead to injury
if the bulb is accidentally damaged
during replacement.<
1. Press the two release catches at the
front while simultaneously turning
them to the left to remove the bulb
holder
2. Remove and replace the bulb.
When cleaning the headlamps,
please observe the following:
>Do not clean by wiping with a dry
cloth (scratches). Never use abra-
sives or strong solvents to clean the
covers
>Remove dirt and contamination (such
as insects) by soaking with BMW Car
Shampoo and then rinsing with plenty
of water
>Always use a deicer spray to remove
accumulated ice and snow Ð never
use a scraper.<
Xenon lampsThe 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
continue driving with great caution
using the fog lamps, provided local
traffic laws do not prohibit this.
Because of the extremely high
voltages involved, any work on the
xenon lighting system should be carried
out by technically-qualified personnel
only. Otherwise, there is a risk of fatal
injury.<

Changing a wheel
Only use original BMW full wheel
covers, otherwise, the trim piece
may not fit securely. The full wheel
cover may not be installed 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 load of any kind.
To do so could cause accidents and
personal injury.
To ensure continued safety, have the
tightness of the lug bolts checked with
a calibrated torque wrench [torque
specification: 72 lb ft (100 Nm)] at the
earliest opportunity.<
When storing a wheel in the spare tire
recess take care to avoid bending the
threaded rod.
If the original BMW light-alloy wheels
have been replaced with other light-
alloy wheels, different lug bolts may be
required.
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).
You can anticipate changes in vehicle
handling such as delayed braking
response, longer braking distances and
sacrifices in roadholding.
The changes in handling characteristics
will be even more pronounced if winter
tires are mounted.
Only one space-saver spare tire
may be mounted at a time. Rein-
stall wheels and tires of the same size
and specification as soon as possible.
Maintain correct tire pressures, refer to
page 24.<
Safety tires
*
Safety tires consist of self-supporting
tires and special rims. The tire rein-
forcement ensures that the tire retains
some residual safety in the event of
pressure drop and driving remains
possible to a restricted degree. The
vehicle is equipped with Tire Pressure
Monitor (RDC) or Flat Tire Monitor,
which indicate a flat tire.Flat tireIf there is a tire failure, the red warning
lamp symbol lights up. A supplemen-
tary gong is also heard.
For additional information on Tire Pres-
sure Monitor (RDC) or Flat Tire Monitor
refer to page 78 or 80.
Reduce vehicle speed carefully to
under 50 mph (80 km/h), avoiding hard
brake applications and steering maneu-
vers.
With the safety tires, you can drive
another approx. 155 miles (250 km) to
reach a safe parking location, a service
station or the nearest BMW center.
With a low vehicle load, this can also be
considerably more than 155 miles
(250 km).

Changing a wheel Battery Fuses
Safety tires are only possible in
conjunction with Tire Pressure
Monitor (RDC) or Flat Tire Monitor.<
If the defective wheel cannot be seen
as such immediately from the outside,
check the tire inflation pressure at all
four wheels.
Have the tires changed by your
BMW center. For safety reasons,
do not have a safety tire repaired. Your
BMW center has the information
needed for working with safety tires
and is equipped with the necessary
special tools.<
If appropriate, please consult your
BMW center to reequip your
vehicle from summer to winter tires Ð or
vice versa.<
Battery careThe battery is absolutely maintenance-
free, that is, the original electrolyte will
normally last for the service life of the
battery under moderate climatic condi-
tions.
Please consult your BMW center
whenever you have any questions
concerning the battery. Since the battery
is absolutely maintenance-free, the
following is for your information only.<
Never disconnect the battery
when the engine is running; the
ensuing voltage surge would seriously
damage the vehicle's onboard elec-
tronic systems. vehicle, leave the engine off at all times.
Connect the charge cables to the termi-
nals in the engine compartment.
Terminal locations, refer to Jump-
starting on page 134.
Return used batteries to a recycling
point or your BMW center. Maintain
the battery in an upright position for
transport and storage. Secure the
battery against tilting during transport.<
The fuses are located in the glove
compartment behind a cover secured
by 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.<
