classes: SAE 0W-40, SAE 0W-30, SAE 5W-40
and SAE 5W-30.
Alternative oil grades
If the approved engine oils are not available, up
to 1 US quart/1 liter of another oil with the fol-
lowing specifications may be used:

Coolant
Do not add coolant to the cooling system
when the engine is hot. Escaping coolant
can cause burns.<
Coolant is composed of equal parts water and a
coolant additive. Not all commercially available
additives are suitable for your BMW. Your BMW
Sports Activity Vehicle Center can recommend
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. Do not open the hood until the engine has
cooled down.
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.
