Tire replacement Tire rotationTire ageThe date on which the tire was manu-
factured is indicated by the code on the
sidewall:
DOT ... 4100 indicates that the tire was
manufactured during week 41 of the
year 2000.
BMW recommends the replacement of
all tires when the tires are no more than
6 years old, even if a tire life of 10 years
is possible.
Spare tires over 6 years old should be
used only in case of emergency. A tire
of this age should be replaced by a new
tire immediately, and should not be
mounted together with new tires.
Between the axlesThe tread wear patterns at the front end
differ from those at the rear Ð the actual
patterns will vary according to indi-
vidual driving conditions. In the inter-
ests of safety and maintaining optimal
handling characteristics, tire rotation is
not recommended.
If a proposed interaxle rotation of tires
is based on economic considerations,
one should consider whether the costs
for the rotation are likely to be recap-
tured by any increase in the service life
of the tires that might be realized. In
principle, interaxle rotation must be
performed in short intervals, with a
maximum of 3,000 miles (5,000 km).
Consult your BMW center for more
information.
Should you decide to rotate the tires, it
is essential to comply with the following:
Rotate tires on the same side only, since
braking characteristics and road grip
could otherwise be adversely affected.
Following rotation, the tire inflation
pressure should always be corrected.If different tire sizes are mounted
on the front and rear axles (refer to
page 12 9), the wheels may not be
rotated from one axle to the other.<

128n
Winter tiresChoosing the right tireBMW recommends winter tires (M+S
radial tires) for driving in adverse winter
road conditions. So-called all-season
tires with the M+S-identification mark
do indeed possess better winter trac-
tion than summer tires with the load
rating H, V, W, Y und ZR, but usually do
not achieve the same level of perfor-
mance as winter tires.
In the interests of safe tracking and
steering response, install radial tires
made by the same manufacturer and
with the same tread configuration on all
four wheels if you elect to mount winter
tires.
Mount only winter tires which have
been approved by BMW. Any BMW
center will be glad to provide you with
information on the best winter tires for
your particular driving conditions.
Do not exceed specified
maximum speeds
Never exceed the maximum speed
for which the tires are rated.
Unprofessional attempts by laymen to
service tires can lead to damage and
accidents.
Have this work performed by skilled
professionals only. Any BMW center
has the required technical knowledge
and the proper equipment and will be
happy to assist you.<
Tire condition, tire pressureOnce the tire wears to below 0.16 in
(4 mm), winter tires display a percep-
tible decrease in their ability to cope
with winter driving conditions, and
should be replaced in the interest of
safety.
Comply with the specified tire inflation
pressures Ð and be sure to have the
wheel and tire assemblies balanced
every time you change the tires.
StorageAlways store tires in a cool, dry place.
Store them away from light whenever
possible. Protect the tires against
contact with oil, grease and fuel.Snow chains
*
The use of narrow-link BMW snow
chains on summer or winter tires is
approved only in pairs and only on the
rear wheels. Comply with all manufac-
turer's safety precautions when
mounting the chains.
BMW 325xi: in a worst-case scenario,
i.e. if your vehicle is stuck on one side
or you cannot access one tire, then only
one chain may be attached to a rear
wheel for a short period of time.
Comply with all manufacturer's safety
precautions when mounting the chains.

Coolant Brake fluidAdding coolant Wait until the engine cools before
removing the cap from the expansion
tank. The needle of the coolant gauge
in the instrument cluster must be
located in the blue zone. If it is not,
there is a danger of scalding.
1 Turn the cap slightly counterclock-
wise in order to allow accumulated
pressure to escape, then open.
2 If the coolant is low, slowly add
coolant until the correct level is
reached Ð do not overfill.
The coolant is a mixture of water and
extended-duty antifreeze with corrosion
inhibitor. Always maintain the
prescribed all-season 50:50 mixture
ratio for year-round protection against
internal corrosion. No other additives
are required.
Replace the coolant every four years.If the brake warning lamp comes on
and the parking brake has been
released:
Check the brake fluid level. Fill it to the
top mark ("MAX") if necessary.
For 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 can result in extended
pedal travel. Comply with the informa-
tion provided on page 120.
460de128
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
(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 inaccessible to 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.<

The BMW Maintenance System has
been designed as a reliable means for
providing maximum driving and operat-
ing 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 DisplayAdvanced technology is employed
to calculate the optimal maintenance
intervals. These are then indicated in
the Service Interval Display. While
conventional systems rely on distance
traveled alone to determine when
service is due, the BMW Maintenance
System has for years considered the 460us112
actual conditions under which the
vehicle operates, because miles can be
traveled in many different ways:
From a maintenance perspective,
62,000 miles (100,000 km) of short-
distance urban driving are not equiva-
lent to 62,000 miles (100,000 km)
covered at moderate speeds in 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 vehi-
cle covers every kind of operating situa-
tion. However, even those who drive
only short distances Ð significantly less
than 6,000 miles (10,000 km) annually Ð
should have the engine oil changed at
least every 2 years since oil deterio-
rates over time, regardless of use.
Service and Warranty Information
Booklet (US models)/Warranty and
Service Guide (Canada models)For additional information on mainte-
nance intervals and procedures, please
refer to the Service and Warranty Infor-
mation Booklet (US models) or to the
Warranty and Service Guide (Canadian
models).
As a precaution against rust, 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.
Your BMW center is always "up to date"
on the latest maintenance work and
repair techniques and equipped with
the required special tools. In addition,
checking parts known from experience
to be subject to wear is a permanent
part of the maintenance specifications.
Be sure that all maintenance work is
confirmed in the Service and Warranty
Information Booklet (US models) or the
Warranty and Service Guide (Canadian
models). These entries will constitute
your proof that the vehicle has received
regular maintenance. They are also
required for warranty claims.<

Caring for your vehicleCaring for the vehicle finish Regular washing is a preventive
measure against long-term effects from
substances that are harmful to the
vehicle's finish, especially if you drive
your vehicle in areas with high levels of
air pollution or aggressive natural
substances (tree resins, pollen).
Nevertheless, you should immediately
remove especially aggressive
substances. Failure to do so can lead to
changes in the paint's chemical
structure or to discoloration. Gasoline
spilled during refueling, oil, grease and
brake fluid should always be cleaned
away immediately, as should bird
droppings.
Any contamination remaining on the
surface of the vehicle will be especially
conspicuous after washing. Use
cleaning fluid or alcohol with a clean
cloth or cotton pad to remove. Remove
tar spots with tar remover. After clean-
ing, the affected areas should be waxed
to ensure continued protection.
Use the cleaning and car-care
products available at your BMW
center.<
Waxing your vehicle Protect the finish using only carnauba
or synthetic-based waxes.
The best way to determine when the
finish needs to be waxed is by noting
when water stops beading on the
surface.
You can use a glass cleaner to remove
any wax or silicone that may have been
left on the windows during waxing.
Use the cleaning and car-care
products available at your BMW
center.<
Paint damageYou can touch up small areas of paint
damage with a BMW spray paint or a
BMW touchup stick.
The paint color code for your car is
provided on a sticker located on the
righthand side under the hood and on
the first page of your Service and
Warranty Information Booklet
(US models) or Warranty and Service
Guide (Canadian models).
Damage caused by flying stones,
scratches, etc., must be touched up
without delay to prevent rust from
forming.
If corrosion has started to form in an
area with paint damage, remove all rust
and clean the area. Then prime the
area with a BMW Primer Stick. Finally,
apply the finish coat. Wait a few days,
then polish the repaired area. Finish by
applying a wax preservative.
More extensive paint damage should
be repaired professionally in accor-
dance with the manufacturer's instruc-
tions. Your BMW center uses original
BMW finish materials in accordance
with approved repair procedures.

OBD interface socket The interface socket for onboard diag-
nostics is located on the driver's side at
the left-hand bottom of the dashboard
and under a cover. The cover has the
letters "OBD" on it.
The purpose of the OBD system is to
ensure proper emission control system
operation for the vehicle's lifetime by
monitoring emission-related compo-
nents and systems for deterioration
and malfunction.460us250
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 possi-
ble opportunity.
If the indicator blinks or flashes, this
indicates a high level of engine misfire.
Reduce speed and contact your near-
est BMW center immediately. Severe
engine misfire over even a short period
of time can seriously damage emission
control components, especially the
catalytic converter.
Service Engine Soon warning

If the fuel filler cap is not properly
tightened, 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 bulbs The lamps and bulbs are essential
factors contributing 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 into 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.
Whenever working on the
electrical system, switch off the
electrical accessory you are working on
or disconnect the cable from the nega-
tive terminal of the battery. Failure to do
this could result in short circuits.
To prevent injuries and damage,
comply with any instructions provided
by the bulb manufacturer.<
The illustration shows the left-hand side
of the engine compartment.1 Low beams H7 bulb, 55 watts2 High beamsH7 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 locks at the front and
turn left to release the bulb holder.
2 Remove and replace the bulb.460de130
When cleaning the headlamps,
please observe the following:
do not clean by wiping with a dry cloth
(scratches). Never use abrasives 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.<

Lamps and bulbsXenon 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 and bulb
replacement should be performed only
by technicians with the appropriate
qualifications. Failure to comply with
this creates a risk of fatal injury.<
