IndexDataTechnologyRepairsCar careControlsOverview
The BMW Maintenance System has
been designed as a reliable means of
providing maximum driving and oper-
ating safety – 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 solely on
distance traveled to determine when
service is due, the BMW Maintenance
System considers the actual conditions
under which the vehicle operates,
because miles can be traveled in many
different ways:
From the point of view of maintenance,
for example, 62,000 miles (100,000 km)
short-distance driving are not equal to
the same 62,000 miles (100,000 km) of
long-distance 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. Those who are outright
"Sunday drivers," driving fewer than
6,000 miles (10,000 km) per year –
should, nevertheless have their oil
changed every 2 years at the most, no
matter what the Service Interval Display
indicates, since engine oil breaks down
over time, regardless of use. 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 rust, it is advis-
able 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 informed 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 in
the Warranty and Service Guide
Booklet (Canadian models). These
entries are your verification for the
regular maintenance of your vehicle
and are required for the performance of
warranty repairs.<

Caring for your vehicleExterior finish To provide effective corrosion protec-
tion, multilayer paintwork is applied at
the factory. Cataphoretic immersion
priming techniques are supplemented
with special body-cavity protectants
and application of specially developed
and extensively tested materials.
A layer of flexible PVC is first applied to
the undercarriage. Following this, a
comprehensive undercoating treat-
ment with a wax-based protectant is
applied. Regular maintenance makes
an important contribution to maintaining
the safety and value of your vehicle.
Increasing awareness of the effects of
harmful environmental factors on
vehicle finishes have led paint and
vehicle manufacturers to initiate
ongoing programs designed to further
improve the durability of their finishes.
Despite this, regional environmental
factors can have negative effects on
your vehicle's finish. Consider these
factors in determining the frequency
and extent of your efforts to maintain
the vehicle finish.
Depending upon material and type of
impact (perforation of paint layer), phys-
ical stresses from sand, road salt,
gravel, etc., can cause corrosion to start extending beneath the finish,
starting at the point of impact.
Road dirt, tar spots, dead insects,
animal droppings (strong alkali effect)
and tree excretions (resins and pollen)
all contain substances capable of
causing damage when allowed to
remain on the finish of your vehicle for
any period of time. This includes spots,
etching, flaking, and separations in the
top coat.
In industrial areas, deposits of flue dust,
lime, oily soot, precipitation containing
sulfur-dioxide (acid rain) and other envi-
ronmental pollutants will damage the
vehicle's finish unless adequate care is
provided – even though this is generally
limited to the outside horizontal
surfaces.
In coastal regions, high levels of atmo-
spheric salt and humidity promote
corrosion.
In tropical zones, high humidity and
heavy ultraviolet radiation prevail, in
addition to temperatures of over 105 7
(+40 6) in the shade. Under these
conditions, light paints can reach
temperatures up to 175 7 (+80 6) and
dark ones up to 250 7 (+120 6).
Caring 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 struc-
ture 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 these
stains. Remove tar spots with tar
remover. After cleaning, the affected
areas should be waxed to ensure
continued protection.
Use the cleaning and car-care
products available at your BMW
center.<

Cleaning and caring for the convertible topCareThe appearance and life of the convert-
ible top depend in large part on proper
care and handling. You should pay
particular attention to the following
instructions if your vehicle has a light-
colored top.
Whenever possible, protect the vehicle
from exposure to intense sunlight by
parking it in the shade so that the paint,
rubber and fabric-covered parts are not
harmed.
Never fold up the convertible top and
store it in the convertible top compart-
ment when wet, dirty or frozen, as
mildew stains and rub spots may result.
To prevent mildew stains, do not keep
the convertible top enclosed in the
convertible top compartment for any
extended period of time.
If the vehicle will be parked for lengthy
periods in an enclosed space, be sure
that the convertible top is dry and that
there is adequate ventilation.
Clean off bird droppings immediately,
since they attack the convertible top
and cause the rubber seals to swell due
to their caustic characteristics.
Besides water, treat rubber seals only
with talcum powder, rubber care prod-ucts or silicone spray, particularly when
they feel dry or tend to stick.
Eliminate noises such as squeaks with
lubricant spray.
Depressions and discoloration may
occur in the convertible top as a result
of improper maintenance and cleaning
or as the result of stresses from exces-
sive use. The convertible top and its
seams may also develop leaks. The
warranty does not cover these situa-
tions. For repairs, please consult your
BMW center.
Washing your vehicleYou can wash your BMW M3 convert-
ible in automatic car washes. Car wash
systems that do not employ brushes
are preferable.
If a brushless car wash is unavailable
and a brush car wash must be used,
modern systems with soft brushes are
preferable. Do not select the wax finish
option. The small amount of beading
wax always used in automatic car
washes will not harm your vehicle's
finish.
In the case of more extensive dirt,
which is definitely visible on light-
colored top materials, clean the top
with the BMW Convertible Cleaning
Set. Please proceed as follows:
Spray the convertible top with the
cleaning agent and then rub with a well-
dampened sponge using circular
motions until a foam develops. Then
you can finish washing the vehicle in an
automatic car wash. After washing your
vehicle 3 to 5 times, you should treat
the convertible top with a special
convertible top impregnating spray.
Please follow the instructions on the
spray can.

Storing your vehicle
If you intend to store the vehicle
for more than 3 months, be sure to
follow the maintenance instructions on
this page.<
Storage preparationsHave your BMW center perform the
following procedures:
1 Clean and apply a rustproofing agent
or other treatment to the engine,
engine compartment, undercarriage,
axles and major components in
accordance with approved repair
procedures. First wash the vehicle
surface, then clean the interior,
following up with paint- and chrome
care, after which you clean the
rubber seals for the hood and doors.
2 Change the engine oil and oil filter
with the engine warm. As an addi-
tional corrosion protection measure,
an anticorrosive agent can be added
to the engine in accordance with the
manufacturer's instructions.
3 Check the coolant level and concen-
tration, top up if necessary.
4 Check the fluid level of the wind-
shield washer fluid reservoir; top up if
necessary.
5 Fill the fuel tank completely to
prevent the formation of condensa-
tion.
6 Increase the tire inflation pressure to
51 psi (350 Kilopascal).Before parking the vehicle1 To prevent the brake discs and
drums from corroding, dry the
parking and footbrake by applying
the brakes.
2 Park the vehicle in a covered, dry,
and well-ventilated area. Place the
transmission in first gear or, if neces-
sary, chock the wheels to prevent the
vehicle from rolling. Do not set the
parking brake.
3 Remove the battery, charge it
completely and store it in a cool (but
frost-free) room.
4 Remove the hardtop and store it
separately. Refer to page 114.
5 Close the convertible top.During storageRecharge the battery every six months.
If it is not recharged, it will not be
useable. Every time the battery is
discharged, especially over extended
periods, its service life is reduced.
Removing the vehicle from
storageRecharge the battery if the "Magic
Eye
*" turns black. Refer to page 157.
Then have Inspection I performed by
your BMW center, including a brake
fluid replacement if necessary.
