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.

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.

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.<
