Engine oil
The engine oil consumption is dependent on 
driving style and driving conditions.
Checking engine oil level
Your vehicle is equipped with an electronic oil 
level check.
The condition for the most accurate indication 
of the oil level possible is measurement with the 
engine at operating temperature, i.e. following 
an uninterrupted drive of at least 6 miles/10 km. 
You can display the oil level on the Control Dis-
play while driving or when stopped on a level 
surface with the engine running.

Your BMW center will be happy to answer 
detailed questions on BMW High Perfor-
mance Synthetic Oil or approved synthetic 
oils.<

Viscosity grades
Viscosity is a measure of an oil's flow rating and 
is specified in SAE grades.
The choice of the right SAE grade is based on 
the climatic conditions in the region in which 
you normally drive your BMW.
Approved oils belong to the SAE grades 
5W-40 and 5W-30.<
These oils can be used for driving at all outside 
temperatures.
Coolant
Do not add coolant to the cooling system 
when the engine is hot. Escaping coolant 
can cause burns.<
Coolant is comprised of water and coolant addi-
tive. Not all commercially available additives are 
suitable 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; observe the instruc-
tions on the containers.<
Comply with the appropriate environ-
mental protection regulations when dis-
posing of coolant additives.<
Checking coolant level
1.The engine must be at ambient tempera-
ture.
2.Turn the cap of the expansion tank counter-
clockwise to allow any accumulated pres-
sure to escape, then continue turning to 
open.3.The coolant level is correct when the cool-
ant level is between the MIN and MAX 
marks, refer to the diagram adjacent to the 
filler neck.
4.If the coolant is low, slowly add coolant up to 
the specified level – do not overfill.
5.Turn the cap until there is an audible click.
6.Have the reason for the coolant loss elimi-
nated as soon as possible.
