Headlamp washer
* and
windshield washer
Capacity approx. 2.65 US quarts
(2.5 liters) for the windshield washer or
5.3 US quarts (5 liters) in conjunction
with the headlamp cleaning system.
Fill with water and - if required - with
antifreeze (according to the manufac-
turer's recommendations).b
We recommend that you mix the
washer fluid before adding it to the res-
ervoir.c
Windshield washer spray
nozzles The spray from the nozzles should be
directed so as to ensure effective
cleaning, even at high speeds.
Use a needle to adjust the nozzles as
required, or have them adjusted by your
BMW Retailer.
Checking oil level As with fuel economy, oil consumption
is directly influenced by your driving
style and vehicle operating conditions.
Consequently you should check the oil
level regularly with the vehicle posi-
tioned on a level surface - approx. every
600 miles (1,000 km), or more fre-
quently if your vehicle is driven under
increased demands.
To obtain precise readings:
dCheck with engine cold, before start-
ing.
dWhen checking with the engine
warm, wait briefly for the oil to drain
back down into the oil pan (e.g.,
while refueling).

Measure the oil level:
1 Pull out dipstick and wipe off with a
lint-free cloth, paper tissue, etc.
2 Push the dipstick all the way into the
guide tube and pull it out again.
3 The oil level should be between the
two marks on the dipstick.
Add oil Wait until the level has dropped to just
above the lower graduation before add-
ing oil. Never wait until the oil drops
below the lower mark.
The space between the two marks on
the dipstick corresponds to approxi-
mately 1.1 US quarts (1 liter). Do not fill
to beyond the upper mark on the dip-
stick. Excess oil harms the engine.
Because it would be consumed within a
short period, it would also result in an
abnormally high rate of oil consump-
tion.a
BMW engines are designed to op-
erate without oil additives; the use of ad-
ditives could lead to damage in some
cases. This also applies to the manual
and automatic transmissions, the differ-
ential and the power steering system.c
Engine oil specificationsAlways refer to the API specifications
when selecting oil.
Required quality:
API SH
API-SH/CD
API-SH/CEViscosity ratingsViscosity = Oil flow rating according to
SAE class.
Select the SAE viscosity rating accord-
ing to the average seasonal air temper-
ature.
Consult the table on the following page
to determine the correct SAE viscosity.
You can continue to operate the vehicle
for short periods of time at tempera-
tures beyond the range for the SAE rat-
ing of the oil being used.A
Always observe all environmental
protection guidelines and regulations
when disposing of used oil.c
Recommendation: have the oil changed
by your BMW Retailer.

Continuous exposure to used oil
has caused cancer in laboratory testing.
Any skin areas that come in contact with
oil should be thoroughly washed with
soap and water.
Always store oil, grease, etc., out of
reach of children. Observe all warning
labels and information on lubricant
containers.
If you use SAE 15W-40 engine oil in low
temperatures below 145F (-10 6) the
engine may become difficult to start.c

The BMW Maintenance System has
been designed as a reliable means of
providing the customer with maximum
vehicle safety and reliability with mini-
mum complication and expense.
Please remember that regular periodic
maintenance plays an essential part in
ensuring continued vehicle security. It
also helps maintain the resale value of
the vehicle.
Service Interval DisplayAdvanced technology is employed to
calculate the optimal maintenance
intervals, which are then indicated in
the Service Interval Display. While con-
ventional maintenance systems rely on
mileage alone to determine when ser-
vice is due, the BMW Maintenance Sys-
tem reflects the actual conditions under
which the vehicle is operated, because
mileage is not simply mileage:
From the point of view of maintenance,
62,000 miles (100,000 km) accumulated
in short-distance driving are not the
equivalent of the same distance cov-
ered in long-distance highway travel.
The BMW Maintenance System
includes the Engine Oil Service as well
as Inspections I and II.
Determining the maintenance intervals
according to the actual loads on the car
covers every kind of operating situation.
However, drivers who cover only
extremely short distances - substantially
less than 6,200 miles (10,000 km) annu-
ally - should have the engine oil changed
at least once a year, as it continues to
age whether or not the car is used on a
regular basis.
Service and Warranty Information
bookletPlease refer to the Service and War-
ranty Information booklet for additional
information on maintenance intervals
and procedures.
Depending on operating conditions, as
a precaution against rust it may be a
good idea to have the body checked for
stone damage and chips at the same
time.
Please ensure that all maintenance
operations are entered in the Service
and Warranty Information booklet upon
completion. These entries will consti-
tute your proof that the vehicle has
received regular maintenance. They
are also required for warranty claims.b
Have your BMW Retailer carry out
the maintenance and repair. Your BMW
Retailer is always informed on the latest
maintenance work and repair tech-
niques and equipped with the required
special tools. In addition, the testing of
parts known from experience to be sub-
ject to wear is a permanent part of the
maintenance specifications.c

Never use spot remover, paint thinner,
solvents, gasoline etc. to remove spots
from the convertible top and from the
rear window, as these substances
destroy the rubber seals and lead to
leaks. Use only BMW-approved clean-
ers.
In addition to the advantage of being
extremely flexible, the rear window also
has the disadvantage of having a rela-
tively soft surface. For this reason, only
clean the rear window with a soft, anti-
static cloth or with BMW Convertible
Rear Window Cleaner.
If you wash the vehicle frequently in
brush car washes, and in particular in
those with hard brushes, faint scratches
in the rear window may result. With the
window replacement system you can
replace a heavily scratched window at a
relatively low price. Please contact your
authorized BMW Retailer for additional
information. b
A full range of car-care products is
available from your BMW Retailer.c
a
Cleaning agents can contain sub-
stances that are dangerous or bad for
your health. Therefore always observe
the warnings and danger notices on the
package.
Open the doors or windows on your ve-
hicle when cleaning the interior.
Never clean your vehicle with solvents
or other materials not specifically in-
tended for this application.c
Hardtop:Please follow the instructions for car
care from page 131.If the vehicle is to be temporarily stored
for more than three months, have the
following maintenance performed by
your BMW Retailer:
1 Cleaning, preservation and retreat-
ment of the engine, engine compart-
ment, underbody, axles and
subassemblies in accordance with
the factory speciÞcations. Vehicle
washing with interior cleaning fol-
lowed by paint and chrome care.
Clean rubber seals of the hood, lug-
gage compartment lid and doors and
rub with either talcum powder or
glycerine oil.
2 Change engine oil and oil Þlter at
operating temperature. As an addi-
tional corrosion protection measure,
an anti-corrosive agent can be added
to the engine in accordance with the
manufacturer's instructions.
3 Check the coolant level and concen-
tration and top up if necessary.
4 Check the acid level in the battery
cells and add distilled water if neces-
sary.
5 Increase the tire inßation pressure to
50.9 psi (3.5 bar).
