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.

Warning lamp for brake hydraulic sys-
tem lights up:
Brake fluid loss resulting in extended
pedal travel.
Fill up to the upper mark (MAX, level
visible from the outside).
Any BMW Retailer can provide you with
information on factory-approved brake
fluids (DOT 4).
a
Brake fluid is hygroscopic, i.e., it
absorbs moisture from the atmosphere
over the course of time. To ensure that
your brake system continues to operate
at maximum efficiency, we strongly rec-
ommend that you have the brake fluid
changed at a BMW Retailer every two
years (refer to pages 71, 105 and 138
and to Service and Warranty Information booklet). Brake fluid is toxic, and also at-
tacks vehicle paintwork. Always store in
the original containers, and keep them
tightly closed, out of reach of children.
When disposing of it, observe the appli-
cable environmental protection laws. Do
not spill brake fluid and do not fill be-
yond the MAX graduation on the reser-
voir. Should it come into contact with
hot engine components, the brake fluid
could catch fire and cause serious
burns.c
A
Please observe the applicable envi-
ronmental protection laws when dis-
posing of used brake fluid.cWith the engine off, unscrew the reser-
voir cap, then reinsert it.
The fluid level should be in between the
graduations on the dipstick.
Use ATF to top up as required. Your
BMW Service representative can pro-
vide you with the fluid specifications.
Start the engine. Pour in more fluid as
required, continuing until it reaches to
between the two marks.
Switch off the engine. The fluid may rise
to about 0.2 inches (5 mm) above the
upper mark.
Screw the reservoir cap back on.
