Engine oil
The engine oil consumption is dependent on
driving style and driving conditions.
Checking the engine oil level with the
dipstick*
1.Park the vehicle on a level surface with the
engine at operating temperature, i.e. after
an uninterrupted drive of at least 6.5 miles/
10 km.
2.Switch off the engine.
3.After approx. 5 minutes, pull out the
dipstick5 and wipe it off with a lint-free
cloth, paper towel or similar material.
4.Carefully push the dipstick all the way back
into the measuring tube and pull it out again.
The oil level must be between the two
markings on the dipstick.
The oil quantity between the two markings on
the dipstick is equivalent to approx. 1 US quart/
1liter.

Under the hood
138 The oil level must not be above the upper
marking of the dipstick. Too much oil will
harm the engine.<
Checking the engine oil level
electronically*
Your car is equipped with an electronic oil-level
monitor.
For a precise measurement and display of the
oil level, it is necessary that the engine be at
operating temperature, i.e. after uninterrupted
driving for at least approx. 6.5 miles/10 km. You
can have the oil level displayed while you are
driving, or while the vehicle is at a standstill on a
level surface and the engine is running.
You can have the oil level reading displayed in
the instrument cluster.
1.Push button 1 in the turn indicator lever up
or down repeatedly until the appropriate
symbol is shown in the display, accompa-
nied by the word "OIL".
2.Press button 2 in the turn indicator lever.
The oil level is checked and the reading dis-
played.
Possible displays
1Oil level OK
2Oil level is being checked.
This can take about 3 minutes if the car is at
a standstill on a level surface, or about
5 minutes while the car is on the move.
3Oil level down to minimum:
Add engine oil as soon as possible, but no
more than 1 US quart/1 liter, refer also to
Adding engine oil on page139.
4Oil level is too high.
Too much oil will harm the engine.
Have the vehicle checked without
delay.<
5The oil level sensor is defective.
Do not add engine oil. You can continue
your journey. Note the newly calculated dis-
tance remaining to the next oil service, refer
to page65. Have the system checked as
soon as possible.

Adding engine oil
Add a maximum of 1 US quart/1 liter of engine
oil no earlier than when the following warning
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 page137.
Add oil within the next 125 miles/200 km;
otherwise, the engine could be dam-
aged.<
Keep oils, greases, etc. out of the reach of
children and comply with the relevant
warnings on the containers. Otherwise, health
hazards may result.<
Oil change
Have oil changed only at your BMW center or at
a workshop that works according to BMW
repair procedures with correspondingly trained
personnel.
Oil types
Do not use oil additives as this could
result in engine damage.<
Specified engine oils
Your service center can advise you on which
engine oils have been approved by the manu-
facturer of your vehicle.
The engine oil quality is critical for the life of the
engine.
Approved oils can be identified by the following
specification:
Approved oils belong to the following viscosity
classes: SAE 0W-40, SAE 0W-30, SAE 5W-40
and SAE 5W-30.
Alternative oil types
If the approved engine oils are not available, up
to 1 US quart/1 liter of another oil with the fol-
lowing specification may be used:
API SM or higher
Coolant
Do not add coolant to the cooling system
when the engine is hot. Escaping coolant
can cause burns.<
Coolant consists of half water and half 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. Because
additives are harmful to your health, it is impor-
tant to follow the instructions on the contain-
ers.<
