lamp lights up in the instrument cluster, or, if the
car has a gasoline engine, when the oil level
monitor shows "+1qt" or "+1l", or, if the car has
a diesel engine, when the oil level has dropped
to just above the lower marking on the dipstick,
refer to page 136.
Add oil within the next 125 miles/200 km,
otherwise the engine could be dam-
aged.<

children and comply with the relevant
warnings on the containers. Otherwise, health
hazards may result.<

a workshop that works according to BMW
repair procedures with correspondingly trained
personnel.

Viscosity ratings
Viscosity is a measure of an oil's flow rating and
is categorized in SAE classes.
Selecting the appropriate SAE class depends
on the regional climatic conditions in which you
normally drive your BMW.
Approved oils belong to the 0W-40,
0W-30, 5W-40 and 5W-30 SAE
classes.<
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.<
