Topping up engine oil

Wait until the level has dropped to just on

the lower dipstick mark before adding oil.

In this area a message also appears on the

Control Display.

Store oil, grease etc., well out of the

reach of children; always observe all

warning labels on the containers.<

Specified engine oils

The quality of the engine oil selected has

critical significance for the operation and

service life of an engine. BMW continu-

ously approves specific oils after confirm-

ing their suitability for use in its vehicles

with extensive testing.

Use only approved BMW High Perfor-

mance Synthetic Oil.

If you are unable to obtain BMW High Per-

formance Synthetic Oil, you can add small

amounts of another synthetic oil between

oil changes. Use only oils with the API SH

specification or higher.

Ask your BMW center for details con-

cerning the specific BMW High Per-

formance Synthetic Oil or synthetic oils

which have been approved.<

You can also call BMW of North America

at 1-800-831-1117 or visit this website:

tion.

BMW engines are designed to oper-

ate without additives, and their use

could even lead to damage in some

cases.<

Viscosity ratings

Viscosity is the oil flow rating as defined in

SAE classes.

The selection of the correct SAE class

depends on the climatic conditions in the

area where you typically drive your BMW.

Approved oils are in SAE classes

5W-40 and 5W-30.<

These oils may be used for driving in all

ambient temperatures.

Coolant

Do not add coolant to the cooling sys-

tem when the engine is hot. Escaping

coolant can cause burns.<

Coolant consists of water and the addition

of antifreeze and anticorrosion agent. Not

all commercially available additives are

suitable for your BMW. Ask your BMW cen-

ter for suitable additives.

Only use suitable additives, as other-

wise engine damage may result. The

additives present a health hazard; observe

the instructions on the containers.<

Always observe all applicable envi-

ronmental rules and regulations when

disposing of used coolant additives.<

Checking coolant level

1. The engine must be at ambient temper-

ature

2. Turn the cap of the expansion tank

counterclockwise to allow any accumu-

lated pressure to escape, then continue

turning to open
