For your own safety
Maintenance and repairs
Advanced technology, e.g. the use of
modern materials and high-performance
electronics, requires specially adapted mainte-
nance and repair methods. Have corresponding
work on your BMW performed only by your
BMW center or a workshop that works accord-
ing to BMW repair procedures with appropri-
ately trained personnel. If this work is not
carried out properly, there is a danger of subse-
quent damage and related safety hazards.<
California Proposition 65 Warning
California law requires us to issue the following
warning:
Engine exhaust and a wide variety of
automobile components and parts,

Engine oil temperature gauge
During normal operation, the engine oil temper-
ature is between approx. 1607/706 and
approx. 3407/1706.
If the engine oil temperature is too high, a mes-
sage is shown on the Control Display.
Fuel gauge
Fuel tank capacity: approx. 18.5 gallons/
70 liters. You can find information on refueling
on page186.
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
After the reserve quantity has been reached, a
message briefly appears on the Control Display;
the remaining range is shown in the computer.
Below a range of approx. 30 miles/50 km, the
message remains on the Control Display.
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.<
Computer
Displays in instrument cluster
To display the information, press the BC button
in the turn signal lever from radio readiness.
The following information is displayed in the
specified order:
>Remaining range
>Average speed
>Average fuel consumption
Cruising range
Displays the estimated remaining range avail-
able with the remaining fuel. The range is pro-
jected based on the driving style over the last
20 miles/30 km.
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.<
Average speed
Periods with the vehicle parked and the engine
off are not included in the calculations of aver-
age speed.
To reset the average speed: press the BC but-
ton in the turn signal lever for approx. 2 sec-
onds.
Average fuel consumption
The average fuel consumption is calculated for
the time during which the engine is running.
You can use the Control Display to view your
fuel consumption rate over two different dis-
tances, refer to Displays on Control Display or
Trip computer.

Technology for comfort, convenience and safety
88 ance adapts to suit driving conditions, varying
from performance-oriented during cornering to
smooth and comfort-oriented when the vehicle
is proceeding in a straight line. During vehicle
operation, the system continuously runs
through closed-loop control cycles lasting only
fractions of a second.
The system assumes operational status each
time you start the engine.
Malfunction
The warning lamp lights up yellow and
a message is shown on the Control Dis-
play. There is a malfunction in the sys-
tem. Have the system checked as soon as pos-
sible.
If a malfunction occurs, please remember
to adapt your speed accordingly, espe-
cially in curves.
The suspension will be noticeably softer and
the vehicle will display a greater tendency to tilt
during cornering and in crosswinds.
If a message stating that you should stop is
shown on the Control Display, stop at a suitable
location and switch off the engine as soon as
possible. In this case the oil level in the reservoir
may have dropped below the minimum, possi-
bly owing to a leak in the hydraulic system. Do
not continue driving, but instead contact your
BMW center.<
FTM Flat Tire Monitor*
The concept
The Flat Tire Monitor keeps track of the infla-
tion pressures in the tires as you drive. The sys-
tem provides an alert whenever the inflation
pressure drops significantly in relation to the
pressure in another tire.
In the event of a pressure loss, the rolling radius
and therefore the rotation speed of the wheels
change. This change is detected and signaled
as a flat tire.
Functional requirement
To ensure the reliable signaling of a flat tire, the
system must be initialized at the correct tire
inflation pressure.
The initialization must be repeated after
every correction of the tire inflation pres-
sure and after every tire or wheel change.<
System limits
The Flat Tire Monitor cannot indicate
sudden severe tire damage caused by
outside factors and does not detect a natural,
even pressure drop in all four tires.<
In the following situations, the system could be
delayed or malfunction:
>System has not been initialized
>Driving on snow-covered or slippery roads
>Sporty driving style: slip in the drive wheels,
high lateral acceleration
>Driving with snow chains
*
Initializing system
The initialization finishes during driving,
which can be interrupted at any time.
When driving resumes, the initialization is auto-
matically continued.
Do not initialize the system when driving with
snow chains

Engine oil
Engine oil consumption depends on driving
style and driving conditions.
Checking engine oil level
Your vehicle is equipped with an electronic oil
level check.
The condition for the most accurate indication
of the oil level possible is measurement with the
engine at operating temperature, i.e. following
an uninterrupted drive of at least 6 miles/10 km.
You can display the oil level on the Control Dis-
play while driving or when stopped on a level
surface with the engine running.
iDrive, for explanation of principle, refer to
page16.1.Press the button.
This opens the start menu.
2.Press the controller to open the menu.
3.Select "Service" and press the controller.

oil level" is selected and press the control-
ler. The oil level is displayed.
Possible messages
>"Engine oil level O.K."
>"No measured value available: Updating
engine oil level measurement...":
Engine oil level is being measured. This
process can take approx. 3 minutes when
stopped on a level surface and approx.
5 minutes while driving.
>"Oil level at the minimum! Refill with 1 quart
of engine oil.":
Add 1 US quart/liter of engine oil at the next
opportunity.
>"Engine oil level too high":
Have the vehicle checked immedi-
ately; otherwise, engine damage may
result if too much oil has been added.<
>"Please observe recalculated service inter-
val for engine oil":
Do not add engine oil. Continued driving is
possible. To do this, observe the recalcu-
lated remaining mileage until the next oil
change service, refer to page199. Have the
system checked as soon as possible.
Adding engine oil
Do not add 1 US quart/1 liter of oil until a corre-
sponding message is shown on the Control Dis-
play.
Add oil within the next 125 miles/200 km,
otherwise the engine could be dam-
aged.<
Continuous exposure to used oil has
caused cancer in laboratory testing.
For this reason, thoroughly wash exposed areas
of skin with soap and water after such work.
Keep oil, grease, etc. out of reach of children
and heed warnings on containers. Failure to do
so could pose health risks.<
Oil change
Have oil changes carried out only 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 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.<

Do not use oil additives; under some cir-
cumstances, they can harm your
engine.<
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 coolant 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
present a health hazard.<
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 it lies
between the Min and Max mark, also refer to
the drawing next 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 it clicks.
6.Have the reason for the coolant loss elimi-
nated as soon as possible.
Brake system
Malfunction
Brake fluid
The warning lamp lights red up in spite
of the handbrake being released; a
message is shown on the Control Dis-
play: stop the vehicle immediately.
The brake fluid in the reservoir has fallen to
below the minimum level. At the same time, a
significantly longer brake pedal path may be
noticeable. Have the system checked immedi-
ately by a BMW center.

Maintenance
BMW Maintenance System
The BMW Maintenance System supports the
preservation of the traffic and operating safety
of your BMW. The service schedule also
includes operations related to the vehicle's
comfort and convenience features, such as
replacement of the filters for the inside air.
The ultimate objective is to ensure economical
maintenance by providing the ideal service for
your vehicle.
Should the day come when you decide to sell
your BMW, you will find that a complete dealer
service history is an asset of inestimable value.
CBS Condition Based Service
Sensors and special algorithms take the differ-
ent driving conditions of your BMW into
account. Condition Based Service uses this to
determine the current and future service
requirements. By letting you define a service
and maintenance regimen that reflects your
own individual requirements, the system builds
the basis for trouble-free driving.
You can set the Control Display to show
remaining distances and times of selected
maintenance intervals and legally mandated
deadlines, refer to page77:
>Engine oil
>Brake pads, front and rear separately
>Microfilter/activated-charcoal filter
>Brake fluid
>Spark plugs>Vehicle check
>Legally required tests depending on local
regulations
Service data in remote control
Your vehicle stores the information required
maintenance continuously in the remote con-
trol during driving. After accessing the data
stored in the remote control, your BMW Service
Advisor can suggest precisely the right array of
service procedures for your own individual vehi-
cle. For this reason, when you take your vehicle
in for service, you should give the BMW Service
Advisor the remote control last used to drive it.
Make sure the date is always set cor-
rectly, refer to page83, as otherwise the
effectiveness of CBS Condition Based Service
is not ensured.<
