Checking oil level
1 Park the vehicle on a level surface.
2 Shut the engine off after it has
reached normal operating
temperature.
3 After approx. 5 minutes, pull the dipstick out and wipe it off with a
clean lint-free cloth, paper towel, or
similar material.
4 Carefully push the dipstick all the way into the guide tube and pull it out
again.
5 The oil level should be in between the
two marks on the dipstick.
As with fuel economy, oil consumption
is directly influenced by your driving
style and vehicle operating conditions.

The oil volume between the two marks
on the dipstick corresponds to approx.
1.1 US quarts (1 liter). Do not fill beyond
the upper mark on the dipstick. Excess
oil will damage the engine.

To add oil
Wait until the level has dropped to just
above the lower mark before adding oil.
However, do not wait until the oil level
drops below the lower mark.
BMW engines are designed to op-
erate without oil additives; the use
of additives could lead to damage in
some cases. This is also true for the
manual transmission, the automatic
transmission, the differential, and the
power steering system. <

167nEngine oil Coolant
Comply with the applicable envi-
ronmental laws regulating the dis-
posal of used oil. <
Recommendation: have the oil changed
by your BMW center. Continuous exposure to used oil
has caused cancer in laboratory
testing. For this reason, any skin areas
that come into contact with oil should
be thoroughly washed with soap and
water.
Always store oil, grease, etc., out of
reach of children. Comply with all warn-
ing labels and information on lubricant
containers. < Do not add coolant to the cooling
system when the engine is hot. If
you attempt to do so, escaping coolant
can cause burns.
To avoid the possibility of damage later
on, never use anything other than fac-
tory-approved, nitrite and amino-free
extended-duty antifreeze with corrosion
inhibitor. Your authorized BMW center
is familiar with the official specifica-
tions.
Antifreeze and anticorrosion agents are
hazardous to health. You should always
store them in their original container
and in a location which is inaccessible
to children.
Extended-duty antifreeze with corro-
sion inhibitor contains the flammable
substance ethylene glycol. For this rea-
son, do not spill antifreeze with corro-
sion inhibitor on hot engine parts. It
could catch fire and cause serious
burns. <
Comply with the applicable envi-
ronmental laws regulating the dis-
posal of extended-duty antifreeze with
corrosion inhibitor. <
Checking coolant level
Correct coolant level when the engine
is cold (approx. 68 7/20 6):
Unscrew the cap from the expansion
tank.
The coolant level is correct when the
upper end of the red float is at least
even with the upper edge of the filler
neck (refer to the arrow in the illustra-
tion), but no more than 0.8 in (2 cm)
above it – that is, up to the second mark
on the float (refer also to the schematic
diagram next to the filler neck).
