Outside temperature warning
When the displayed temperature sinks to
approx. +377/+36, a signal sounds and a
warning lamp lights up. There is an increased
risk of black ice.
Black ice can also form at temperatures
above +377/+36. You should there-
fore drive carefully on bridges and shaded

Engine oil
The engine oil consumption is dependent on
driving style and driving conditions.
Checking oil level
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, e.g. 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.
Display in the instrument cluster
1.Lightly push button 1 in the turn indicator
stalk up or down repeatedly until the appro-
priate symbol is shown in the display,
accompanied by the word "OIL".
2.Press button 2 in the turn indicator stalk.
The oil level is checked and the reading dis-
played.

Too much oil will harm the engine.
Have the vehicle checked without
delay.<
>"Please observe recalculated service inter-
val for engine oil"
Do not add engine oil. You can continue
your journey. Note the newly calculated dis-
tance remaining to the next oil service, refer
to page74. Have the system checked as
soon as possible.
Adding engine oil
Do not add the maximum amount of 1 US quart/
1 liter of engine oil until a corresponding mes-
sage is shown on the Control Display.
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 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.
Specified engine oils
The quality of the engine oil selected has critical
significance for the operation and service life of
an engine. BMW continuously approves spe-
cific oils after confirming their suitability for use
in its vehicles with extensive testing.
Only use approved BMW High Performance
Synthetic Oil.If BMW High Performance Synthetic Oil is not
available, you can add small quantities of other
synthetic oils in between oil changes. Only use
oils with the API SH specification or higher.
Your BMW Center will be glad to answer
any questions regarding BMW High Per-
formance Synthetic Oil or approved synthetic
oils.<
You can also call BMW of North America at
1-800-831-1117 or visit the website
www.bmwusa.com to obtain this information.
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
1.The engine must be at ambient tempera-
ture.
2.Turn the cap of the expansion tank a little
counterclockwise to allow any accumulated

Under the hood
202 pressure to escape, then continue turning
to open.
3.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.
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.
Brake system
Malfunctions
Brake fluid
The warning lamps light up in red
even though the handbrake has been
released. A message appears on the
Control Display. Stop immediately.
The brake fluid in the reservoir has fallen to
below the minimum level. At the same time, a
considerably longer brake pedal travel may be
noticeable. Have the system checked without
delay.
Display of this malfunction on Cana-
dian models.
If you continue to drive the car, you may
have to depress the brake more and brak-
ing distances may be significantly longer.
Please adapt your driving style accordingly.<
Brake pads
The warning lamps light up in red
even though the handbrake has been
released. A message appears on the
Control Display. The brake pads have
reached the safe limit for pad wear. Have brake
pads replaced immediately.
Display of this malfunction on Cana-
dian models.
For your own safety: use only brake pads
that BMW has approved for the corre-
sponding vehicle model. BMW is unable to
assess the suitability of brake pads it has not
approved and therefore cannot guarantee their
safety.<
