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 5W-40 and
5W-30 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.

Coolant is a mixture of water and an 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

are hazardous to your health.

Comply with the appropriate environ-
mental protection regulations when dis-

posing of coolant additives.

Checking coolant level

The engine must be at ambient tempera-
ture.

Turn the cap of the expansion tank a little
counterclockwise to allow any accumulated

pressure to escape, then continue turning
to open.

The coolant level is correct if it is between
the maximum and minimum marks in the
filler neck, refer also to the diagram next to
the filler neck.

If the coolant is low, slowly add coolant up to
the specified level; do not overfill.

Turn the cap until there is an audible click.

Have the reason for the coolant loss elimi-
nated as soon as possible.
