Under the hood
Never attempt to perform any service or
repair operations on your vehicle without
the required professional technical training.
If you do not know what repair procedures to
follow, have work on your vehicle done only by
your BMW center or a workshop that works
according to BMW repair procedures with cor-
respondingly trained personnel. If this work is
not carried out properly, there is a danger of
subsequent damage and related safety haz-
ards.<

Opening
Press the release handle and open the hood. Do
not open the hood until the engine has cooled
down.
Closing
Close the hood from a height of approx. 16 in/
40 cm with momentum. It must be clearly heard
to engage.
Make sure that the closing path of the
hood is clear, otherwise injuries may

Adding engine oil
Do not add 1 US quart/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 SM 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.
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 composed of equal parts water and a
coolant additive. 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.Do not open the hood until the engine has
cooled down.
2.Turn the cap of the expansion tank counter-
clockwise to allow any accumulated pres-
sure to escape, then continue turning to
open.

Socket for OBD Onboard
Diagnostics interface
Components which are decisive for the
exhaust-gas composition can be checked via
the OBD socket with a device.
This socket is located to the left on the driver's
side, on the underside of the instrument panel
under a cover.
Exhaust-gas values
The warning lamp lights up. The
exhaust-gas values worsen. Have the
vehicle checked as soon as possible.
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 causes serious damage
to the emission-relevant components, espe-
cially the catalytic converter, within a short time.
If the fuel filler cap is not properly tight-
ened, the OBD system will assume that
fuel vapor escapes. Then a display lights up. If
the cap is then tightened, the display will go out
within a few days.<
Event Data Recorders
Your vehicle may be equipped with one or sev-
eral measuring and diagnosis modules, or with
a device for recording or transmitting certain
vehicle data or information. If you have also sub-
scribed to BMW Assist, certain vehicle data can
be transmitted or recorded to enable corre-
sponding services.

Care
Car-care products
Regular cleaning and care make a significant
contribution to retaining your BMW's value.
For the cleaning and care of your vehicle, BMW
recommends using only products that BMW
has approved for this purpose.
Your BMW Service will be glad to advise you
about products and services for the cleaning
and care of your BMW.

cient ventilation in enclosed spaces. Use only
products that are formulated for vehicle clean-
ing.<
Care exterior
Washing your vehicle
In the winter months, it is especially
important to ensure that the vehicle is
washed on a regular basis. Otherwise, signifi-
cant soiling and road salt can cause damage to
the vehicle.<
Failure to do so may lead to a reduction in
braking efficiency and also to corrosion of
the brake rotors.<
Car washes
Give preference to cloth car washes.
Before driving into the car wash, make sure that
it is suitable for your BMW. Pay attention to the
following points:

mirrors, refer to page53.
>Maximum permissible tire width.
Preparations for driving into the car wash:
>Deactivate rain sensor to prevent unwanted
wiper activation.
>Deactivate rear window wiper
* and protect
it from damage. Take appropriate protec-
tive measures; inquiring with the car wash
operator as needed.
>Remove additional add-on parts, e.g. spoil-
ers or phone antennas, if they could be
damaged.
Automatic transmission
Before driving into the car wash, make sure the
vehicle is able to roll by making sure to:
1.Insert the remote control into the ignition
lock, even with comfort access.
2.Shift into transmission position N.
3.Release the parking brake.
4.Switch off the engine.

is still possible when no mobile phone is
paired with the vehicle.
>BMW Assist is activated.
Activating BMW Assist, refer to page215.
>Radio readiness is activated.

been deactivated, emergency requests are not
possible. The BMW Assist system can be reac-
tivated by a BMW center after signing a new
contract.

arrangement of the switches and indicator
lamps may differ somewhat.
2.Press the SOS button for at least 2 sec-
onds.The LED in the button lights up. As soon as the
voice connection to the BMW Assist Response
Center has been established, the LED flashes.

Assist Response Center can take further steps
to help you under certain conditions.
If conditions allow, remain in the vehicle until
the connection has been established. You will
then be able to provide a detailed description of
the situation.
If the current position of your vehicle can be
determined, it will be transmitted to the BMW
Assist Response Center.
If the LED is flashing but the BMW Assist
Response Center cannot be heard over the
hands-free system, it is possible that the
hands-free system is malfunctioning. The BMW
Assist Response Center may still be able to
hear you, though.

request is automatically initiated immediately
after a severe accident. Pressing the button
does not interfere with this.

cannot be guaranteed under unfavorable condi-
tions.
