Practical interior accessories
112 The corresponding memory button 1 is now
programmed with the signal of the original
hand-held transmitter.
You can operate the system when the engine is
running or when the ignition is switched on.
If the device can not be used after
repeated programming, check whether
the original hand-held transmitter uses an alter-
nating-code system. To do so, either read the
instructions for the original hand-held transmit-
ter or hold down the programmed memory
button1 of the integrated universal remote
control. If the LED2 on the integrated universal
remote control flashes rapidly for a short time
and then remains lit for approx. 2 seconds, this
indicates that the original hand-held transmitter
uses an alternating-code system. In the case of
an alternating-code system, program the mem-
ory buttons1 as described at Alternating-code
transmitters.<
Alternating-code transmitters
To program the integrated universal remote
control, consult the operating instructions for
the equipment to be set. You will find informa-
tion there on the possibilities for synchroniza-
tion.

Engine oil
The engine oil consumption is dependent 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.

controller until "Service requirements" is
selected and press the controller.
5.Change to the second field from the top if
necessary. Turn the controller until "Engine
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 page209. 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, any skin areas that come into
contact with oil should be thoroughly washed
with soap and water.
Keep oil, grease etc. out of reach of children and
observe the warnings on the containers to pre-
vent health risks.<
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.
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.
Do not use oil additives, as these may
result in engine damage.<
Only use 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. Only
use oils of the specification API SH or higher.

Viscosity grades
Viscosity is a measure of an oil's flow rating 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 add coolant to the cooling system
when the engine is hot. Escaping coolant
can cause burns.<
Coolant is comprised of water and coolant addi-
tive. 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.<
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 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 level is between the MIN and MAX
marks, 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.Turn the cap until there is an audible click.
6.Have the reason for the coolant loss elimi-
nated as soon as possible.

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, a complete dealer service history
will prove to be 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 mandated inspections 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. You should therefore hand over the remote
control you last used to drive to the BMW Ser-
vice Advisor when you take your vehicle in for
service.
Make sure the date is always set cor-
rectly, refer to page83, as otherwise the
effectiveness of CBS Condition Based Service
is not ensured.<

Display of the previously described
malfunction in Canadian models.
The lamp flashes under certain conditions. This
is a sign of excessive misfiring of the engine. In
this case you should reduce speed and drive to
the nearest BMW center as soon as possible.
Heavy engine misfiring led to serious damage
to the emission-relevant components, espe-
cially the catalytic converter, within a short time.
