Add at least 0.5 US quart/0.5 liter of oil, other-
wise the oil level check cannot reliably display
the current oil level.

Continuous exposure to used oil has
caused cancer in laboratory testing.

For this reason, thoroughly wash exposed areas
of skin with soap and water after such work.
Keep oil, grease, etc. out of reach of children
and heed warnings on containers. Failure to do
so could pose health risks.

For immediate updating of the oil level
display, carry out a quick measurement

directly afterward.

Oil change

Have oil changes carried out only by a BMW
center or a repair shop that works in accordance
with BMW guidelines and uses appropriately
trained personnel.

Approved engine oils

The quality of the engine oil selected has critical
significance for the operation and service life of
an engine. BMW continuously approves spe-
cific oils after confirming their suitability for use
in its vehicles with extensive testing.

Do not use oil additives; under some cir-
cumstances, they can harm your

engine.

Your BMW center will be happy to answer
detailed questions on BMW High Perfor-

mance Synthetic Oil or approved synthetic
oils.

You can also call BMW of North America at
1-800-831-1117 or visit the website at

Viscosity grades

The viscosity is a measure of the thickness of
the oil and is specified in SAE grades.

Approved oils belong to the SAE grade
10W-60.

Alternative oil types

If BMW High Performance Synthetic Oil is
unavailable, you can add small quantities of
other synthetic oils between oil changes.
Only use oils with the following specifications:

SAE 10W-50

Low ambient temperatures

The oils used by BMW from the factory for your
vehicle model can be used at virtually all ambi-
ent temperatures. However, if the vehicle is
operated for a longer period at temperatures
below –4

7/–206, your BMW center will be

happy to recommend a suitable oil.

Coolant

Do not open the cooling system when the
engine is hot. Escaping coolant can cause

burns.

Coolant consists of water and coolant additive.
Not all commercially available additives are suit-
able for your BMW. Ask your BMW center for
suitable additives.

Only use suitable additives, otherwise
engine damage may result. The additives

present a health hazard.

Always observe all applicable environ-
mental laws and regulations when dis-

posing of used coolant additives.

Checking coolant level

The engine must be at ambient tempera-
ture.

Turn the cap of the expansion tank counter-
clockwise to allow any accumulated pres-
sure to escape, then continue turning to
open.
