Everything under control
70
Coolant temperature
A warning lamp will come on if the coolant, and
therefore the engine, becomes too hot. In addi-
tion, a message will appear on the Control Dis-
play.
Check coolant level, refer to page210.
Engine oil temperature*
When the engine is at normal operating temper-
ature, the engine oil temperature is between
approx. 2107/1006 and approx. 3007/
1506.
If the engine oil temperature is too high, a mes-
sage appears on the Control Display.
Fuel gauge
Fuel tank capacity: approx. 15.9 US gallons/
60 liters.
You can find information on refueling on
page192.
If the tilt of the vehicle varies for a longer period,
when you are driving in mountainous areas, for
example, the indicator may fluctuate slightly.
Reserve
Once the fuel level has fallen to the reserve
zone, a message briefly appears on the Control
Display and the cruising range for the remaining
amount of fuel is displayed on the computer.
Under a cruising range of approx. 30 miles/
50 km, the message remains in the Control Dis-
play.
Refuel as soon as possible once your
cruising range falls below 30 miles/
50 km, otherwise engine functions are not
ensured and damage can occur.<

Calling up information
Press the button in the turn indicator lever.
The following items of information are dis-
played in the order listed:
>Cruising range
>Average speed
>Average fuel consumption
>Current fuel consumption
*
>No information
To set the corresponding units of measure,
refer to Units of measure on page72.
Cruising range
Displays the estimated cruising range available
with the remaining fuel. The range is calculated
on the basis of the way the car has been driven
over the last 18 miles/30 km and the amount of
fuel currently in the tank.

Engine oil
The engine oil consumption is dependent on
driving style and driving conditions.
Checking engine 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, 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.
Display 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.

>"Measurement inactive. Have this
checked."
Do not add engine oil. You can continue
your journey. Note the newly calculated dis-
tance remaining to the next oil service, refer
to page73. Have the system checked as
soon as possible.
Adding engine oil
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 y our B MW c ente r o r a t
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.
Do not use oil additives as these may
cause engine damage.<
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. For gaso-line engines, only use oils with the API SM
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 0W-40,
0W-30, 5W-40 and 5W-30 SAE
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 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.<
Comply with the appropriate environ-
mental protection regulations when dis-
posing of coolant additives.<

Checking coolant level
1.Do not open the engine hood before the
engine has cooled down.
2.Turn the cap of the expansion tank a little
counterclockwise to allow any accumulated
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.
