for the correct operation and long life of your
car's engine. On the basis of extensive tests,
BMW regularly approves specific grades of
engine oil.
BMW Service will be able to inform you
which oil grades of viscosity SAE 10W-60
are approved for your car by
Do not use any oil additives, as these
could in certain circumstances result in
engine damage.<
Alternative oil grades
If exceptionally none of the approved grades of
oil is available, you can top up the oil level in
between oil changes with other grades of oil.
The oil specification on the container must be
one of the following:
> Viscosity:
Preferred: SAE 10W-60;
Alternatively: SAE 10W-40, SAE 5W-50 or
SAE 10W-50

Coolant
Do not open up the cooling system while

Coolant consists of water and an antifreeze and
corrosion inhibitor additive. Not all commer-
cially available additives are suitable for your
BMW. BMW Service can provide details of
which additives are suitable.
Use only suitable additives, otherwise the
engine could incur damage. As these
additives are hazardous to health, observe the
notes on the containers.<
When disposing of coolant additives,
comply with the relevant environmental
protection regulations.<

Checking coolant level

1. The engine must be at ambient tempera-
ture.
2. Turn the cap on the expansion tank slightly
anti-clockwise until it starts to open, then
allow the pressure to escape before open-
ing it fully.
3. The coolant level is correct if the top end of
the float rod is on a level with the upper
edge of the filler neck, see also diagram next
to the filler neck.
4. If necessary, slowly top up to the correct
level; do not overfill.
5. Turn the cap to close until it is heard to click.
