OverviewControlsMainte-RepairsDataIndex
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 its resale
value.
Service Interval DisplayWhile conventional systems rely on
milage alone to determine when service
is due, the BMW Maintenance System
reflects the actual conditions under
which the vehicle is operated: some
miles are more strenuous than others.
From a maintenance point of view,
62,000 miles (100,000 km) accumu-
lated in short-distance urban driving are
not the equivalent of the same distance
covered at moderate cruising speeds in
long-distance highway travel.
The BMW Maintenance System moni-
tors actual operating conditions as the
basis for defining when the Engine Oil
Service and Inspections I and II are
due.
This service strategy accurately reflects
your own vehicle's specific needs by
defining maintenance intervals
according to individual operating condi-
tions. However, drivers who cover only
extremely short distances Ð substan-
tially 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 regardless of whether
the vehicle is used on a regular basis.
Service and Warranty Information
Booklet (US models)/Warranty
and Service Guide Booklet
(Canadian 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, if
your vehicle is exposed to potential
damage from unimproved road
surfaces we suggest that you have the
body checked for damage from stone
chips and gravel at the same time.
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 socketThe interface socket for onboard diag-
nostics is located on the left-hand side
of the driver's side, behind a specially
marked cover located beneath the
instrument 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. However, the systems should
be checked by your BMW center at the
next 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
warning lamp for Canadian
models.
If the fuel filler cap is not on tight
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 bulbsLow and high beamsEngine compartment, left side:
1 Low beam
2 High beam
H7 bulb, 55 watts
The H7 bulb is pressurized. There-
fore, wear safety glasses and
protective gloves. Failure to comply
with these precautions can result in
physical injury if the bulb breaks.<
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 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
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
lighting system should be carried out by
technically-qualified personnel only.
Otherwise, there is a risk of fatal
injury.<

Changing a wheel
Safety precautions for replacing
flat tires and all wheel changes:
Stop the vehicle as far as possible from
passing traffic. Park on a firm, flat,
surface. 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
(selector lever in Park with automatic
transmission) 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
surface.
Do not place wooden blocks or similar
objects under the jack. They could
prevent 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 Ð risk of fatal injury.<
Your BMW is equipped with a space-
saver spare tire designed for temporary
use in maintaining the vehicle's mobility
in an emergency.
To remove the space-saver spare
tire, lift the floor panel in the
luggage compartment completely out,
refer to page 35.<
What you will needIn order to avoid rattling noises later,
note the position of the tools when you
remove them and return them to their
original position when you are through
using them.
>Jack 1
Raise the floor panel in the luggage
compartment, refer to page 35 and
undo the jack (arrow).
When you have completed work, fold
the handle back and insert it in its
holder
>Chock 2
Located behind the jack on the wall
in the luggage compartment. Loosen
the wingnut to remove it

Changing a wheel8. Remove accumulations of mud and
dirt from the mounting surfaces of
the wheel and hub. Clean the lug
bolts
9. Position the new wheel or the
space saver spare tire on the hub
and screw at least two lug bolts
finger-tight into opposite bolt holes
10. Screw in the remaining lug bolts
and screw in all the bolts in a diag-
onal pattern
11. Lower the jack and remove it from
beneath the vehicle
12. Tighten the lug bolts securely in a
diagonal pattern
13. Wheels with full wheel covers
*:
Place the wheel cover with the
valve opening (arrow) over the
valve. Use both hands to press the
cover securely onto the rim
14. Check and correct the tire inflation
pressure at the earliest opportunity.
Vehicles with Tire Pressure Monitor
(RDC)/Flat Tire Monitor:
After mounting the spare tire or
correcting the tire inflation pres-
sure, reactivate the system, refer to
page 83 or 85.
Protect valve stems and valves from dirt
using screw-on valve stem caps. Dirty
valve stems frequently lead to slow
pressure loss.
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 lug wrench [torque specifi-
cation: 72 lb ft (72 100 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.

Battery FusesBattery careThe 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. The battery is
completely maintenance-free; the
following section is provided 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.<
Charging the batteryWhen charging the battery in the
vehicle, 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-
starting on page 140.
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.<
