proper maintenance plays a role in maintaining full protection
under
BMW's new car warranty coverage. If in doubt about
the terms and conditions of your car's warranty, an autho-
rized BMW dealer should be able to explain them to you.

Service Interval lndicator (Sll)
The BMW Service Interval lndicator (SII) notifies the driver
when oil change and other service is required. The
Sll dis-
plays the phrase "OIL SERVICE"
or"INSPECTI0N" and 7
light emitting diodes (LEDs) in the Instrumentcluster: 5green,
one yellow and one red.
For the
1997 and later 5 Series, BMW introduced an oil
change interval based on fuel consumption. The advantages
of this system are:
Fuel consumption is an accurate method of determining
engine load and the need for service.
The processing electronics are simple.
Resetting of indicator before the scheduled time will not
affect the time to the next service.
4 The Sll is programmed to measure a set volume of con-
sumed fuel. This volume varies between models, dependent
on vehicle and engine size. The
Sil control unit receives a
signal from the engine control module (ECM) when the vehi-
cle is in use. As
20% of the programmed fuel volume is con-
sumed, one of the green LEDs will go out. Each successive
20% of fuel consumption will cause the next LED to go out
until
100% of the measured volume has been consumed. At
this point the yellow LED will come on, indicating that service
is due. When
108% of the measured volume has been con-
sumed, the red LED will illuminate, indicating that service is
overdue.
Service Interval Indicator (SII), resetting
After the specified maintenance has been carried out, the Sll
memory should be reset.
NOTE-
For reference, the BMW oil service requirements are approx-
imately equivalent to the maintenance tliat other European
manufacturers specify at intervals with a maximum of every
15.000 miles or I2 months.

be used. Instead, the
Sll can be reset with the trip odometer
reset button in the instrument cluster.
Make sure ignition key is in OFF position.
* Press and hold trip odometer button in instrument cluster,
and turn ignition key to ACCESSORY position.
Keep
button pressed for approximately 5 seconds until
either of following appear in display: OIL SERVICE or
INSPECTION, with RESET.
Press button again and
hold for approximately 5 seconds
until RESET flashes.

Maintenance
0 Service due is shown with RESET if the measured con-
sumption limit has been reached and resetting is possible.
If RESET is not shown, the minimum limit has not been
reached and resetting is not possible.
While display is flashing, press button briefly to reset
Sll.
After display has shown new interval, the following will
appear in display for approximately
2 seconds: END SIA.
NOTE-
The system can only be reset again after the vehicle has
been driven approximately 50 to
75 miles (consumes at
least2.5gallons of fuel). If the display shows RESETwhen
resetting, the minimum driving distance has been fulfilled
and the system can be reset again.
0 It is possible to interrupt and end the reset procedure by
changing the position of the ignition
ley.
lnspection I, lnspection II
The Service Interval Indicator (SII) signals the need for main-
tenance and inspection. There are two sets
of inspection re-
quirements, alternating throughout a car's maintenance
history. If the last inspection interval was lnspection I, the next
inspection interval (following an oil service) will be lnspection
11, the next after that will be lnspection I, and so on.
lnspection
I tasks are listed in Table b. lnspection I Service.
lnspection
II includes most of the tasks from lnspection I with
additional lnspection
II tasks. A complete listing of lnspection
II tasks is in Table c. lnspection I1 Service.
NOTE-
For reference, the BMW lnspection I and lnspection I1 re-
quirements are approximately equivalent to the maintenance
requirements that other European manufacturers specify.
ln-
spection I is normally due at intervals with a maximum of
30,000 miles or
24 months. lnspection I1 is normally due at
intervals with a maximum of 60,000 miles or
48 months.

NOTE-
Castrol supplies the mineral and synthetic oil recommend-
ed by
BMW
BMW High Performance synthetic oil may be used in all
E39 models, regardless of year.
The use of engine oil additives is not recommended when
using BMW High
Performance synthetic engine oil.
* BMW is constantly upgrading recommendedmaintenance
procedures and requirements. The information contained
here is as accurate as possible at the time ofpublication. If
there is any doubt about what procedures apply to a spe-
cific
model or model year, or what intervals should be fol-
lowed, remember that an authorized BMW dealer has the
latest information on factory-recommended maintenance.
CAUTIOIG
In the case of cars that accumulate very low mileage per
yea/; BMW recommends that the engine oil should be
changed once
a year at a minimum, regardless of whether
mineral or synthetic based oil is used.
In the interest of engine longevity, use half
tlie recom-
mended engine oil change interval.
Engine oil, checking level
4 Engine oil level is checked with a dipstick (arrow) in the
engine block (6-cylinder oil dipstick shown,
V-8 dipstick is
similar).
- Check oil level with car on level surface, after engine has
been stopped for at least a few minutes.
- Check level by pulling out dipstick and wiping it clean
Reinsert it all the way and withdraw it again.

4 If oil level is low, add oil by removing oil filler cap (arrow) on
top of cylinder head
(6-cylinder oil cap shown, V-8 is sirnilar).
- Add only amount needed to bring oil level to upper mark on
dipstick, using an oil of correct viscosity and grade.
Engine oil and filter, changing
A complete oil change requires new oil, a new filter insert kit,
and a new drain plug sealing washer. The tools needed, a
17
mm drain plug socket or box wrench, a 36 mm socket or
wrench, and a drain pan (8
- 10 US qt. capacity), are de-
scribed in
010 General.
NOTE-
If using a "fast 1ube"service facility for oil changes, make sure
the technician hand-starts and torques the engine oil drain
plug using hand-tools. Power tools can strip the threads of
the plug and the oil pan.
Run engine for afew minutes to warm engine oil. Shut engine
off.
With car on level ground, place drain pan under oil drain plug.
Using a
36 mm socket, loosen and remove oil filter housing
cover (arrow). Remove filter cartridge and discard any
0-
rings (V-8 engine oil filter housing shown, 6-cylinder oil filter
housing is sirnilar).
Using a socket or box wrench, loosen drain plug at oil drain
pan. Remove plug by hand and let oil drain into pan
(V-8 en-
gine oil drain plug shown, 6-cylinder drain plug is similar).
WARNING -
Pull the loose plug away from the hole quicldy to avoid being
scalded by hot oil. It will run out
quiclcly when the plug is re-
