of fuel:
>750i/Li: approx. 2.6 gallons/10 liters.
>760i/Li: approx. 3.1 gallons/12 liters.

Engine oil
The engine oil consumption depends on driving
style and driving conditions.
Checking oil level
Your vehicle is equipped with an electronic oil
level control.
To obtain the most accurate possible oil level
reading, the measurement should be taken
when the engine is at operating temperature,
i.e. following an uninterrupted drive of at least
6 miles/10 km. You can display the oil level
while driving or when stopped on a level surface
with the engine running.
The current oil level can be viewed on the Con-
trol Display.
iDrive, for principle details, refer to page16.1.Press the button to open the start
menu.
2.Move the controller toward "Car Data".
3.Select and press the controller.
The oil level is displayed.
Turn the controller to exit the list.

>"No measurement possible at this time".
Adding engine oil
Do not add oil until a Check Control message
appears.
Add oil within the next 125 miles/200 km;
otherwise, the engine could be dam-
aged.<
Keep oil, grease, etc. out of reach of chil-
dren and heed warnings on the contain-
ers to avoid health risks.<
Oil changing
Only have an oil change carried out by a BMW
center or a repair shop that works in accordance
with BMW guidelines and uses appropriately
trained personnel.
Approved 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 engine oils after confirming their suitability
for use in its vehicles with extensive testing.
Use only approved BMW High Performance
Synthetic Oil.
If BMW High Performance Synthetic Oil is
unavailable, you can add small quantities of
other synthetic oils between oil changes. Use
only oils of the specification API SH or higher.
Your BMW center will be happy to answer
detailed questions on BMW High Perfor-
mance Synthetic Oil or approved synthetic
oils.<
You can also call BMW of North America at
1-800-831-1117 or visit the website at
www.bmwusa.com to obtain this information.
Never use oil additives as they can dam-
age your engine under some circum-
stances.<
Viscosity grades
The viscosity is a measure of the thickness of
the oil and is specified in SAE grades.
The choice of the right SAE grade is based on
the climatic conditions in the region in which
you normally drive your BMW.
Approved oils belong to the SAE grades
5W-40 and 5W-30.<
These oils can be used for driving at all outside
temperatures.
Coolant
Do not open the cooling system when the
engine is hot. Escaping coolant can cause
burns.<
Coolant consists of water and supplemental
antifreeze and anticorrosion agents. Not all
commercially available additives are suitable for
your BMW. Ask your BMW center for suitable
additives.
Only use suitable additives; otherwise,
engine damage may result. The additives
present a health hazard; observe the instruc-
tions on the containers.<

Under the hood
204 Always observe all applicable environ-
mental laws and regulations when dis-
posing of used coolant additives.<
Checking coolant level
1.The engine must be at ambient tempera-
ture.
2.Turn the cap of the expansion tank counter-
clockwise to allow any accumulated pres-
sure to escape, then continue turning to
open.
3.The coolant level is correct when the cool-
ant extends to between the MIN and MAX
marks on the filler neck, refer to the diagram
adjacent to the filler neck.
4.If the coolant is low, slowly add coolant up to
the specified level – do not overfill.
5.Twist closed the cap and tighten firmly.
6.Have the reason for the coolant loss elimi-
nated as soon as possible.
Brake system
Malfunction
Brake fluid
The warning lamp lights up and a mes-
sage is shown on the Info 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 immedi-
ately.Warning lamp on Canadian models
During continued driving increased brake
pedal travel may be necessary, and con-
siderably longer braking distances may result.
Please adapt your driving style accordingly.<
Brake pads
For messages and indicator lamps on the Info
Display, refer to page80.
For your own safety: use only brake pads
that BMW has approved for your particu-
lar vehicle model. As BMW cannot assess the
suitability of other brake pads for use on your
vehicle, we are unable to assume continued
responsibility for the vehicle's operating safety
if non-approved pads are installed.<
