Tips for pleasant drivingUse the automatic mode – switch on
with AUTO button 6. Select the desired
interior temperature.
Detailed setting options are described
for you in the following sections.
You can make the settings of your
vehicle in such a manner that,
when you unlock the vehicle with the
remote control of your personal key,
your own personalized setting for the
automatic climate control is initiated. The AUTO program adjusts the
air supply and the air distribu-
tion to the windshield and the side win-
dows, towards the upper body and to
the footwells, and in addition adapts
the temperature to external influences:
e.g. summer, winter.
The cooling function is automatically
switched on when you are using the
AUTO program.
Individual air distribution
You can cancel the AUTO pro-
gram by selecting specific dis-
tribution patterns to suit your
own individual requirements.
While the AUTO program is then deacti-
vated, the automatic airflow control
remains in operation. Air flows onto
the windows , toward the upper
body , and into the footwell . You
can reactivate the automatic air supply
by pressing the AUTO button.Temperature
The interior temperature that
appears in the display panel is a
general figure intended for refer-
ence purposes. We recommend
727/+226 as a comfortable setting,
even if the air conditioning is on. When
you start the vehicle, the system
ensures that the selected temperature
is reached as quickly as possible. It
then maintains this temperature,
regardless of the season.
To select the units of measure 7/6
of the display, refer to page 83.
Air supply/Blower
By pressing the upper or lower
button, you can vary the air sup-
ply. This deactivates the auto-
matic air supply – the AUTO display dis-
appears from the panel. Nevertheless,
the automatic air distribution remains
unchanged. You can reactivate the
automatic air supply by pressing the
AUTO button.
When the lowest blower speed is set
and you press the lower button, all of
the displays are canceled: the blower,
heating and air conditioner are
switched off, and the air supply is
stopped. You can reactivate the system
by pressing any button for the auto-
matic climate control.To defrost windows and remove
condensation
This program quickly removes
ice and condensation from the
windshield and the side windows.
Air conditioning
The air is cooled and dehumidi-
fied and – depending on the
temperature setting – rewarmed.
Depending on the weather, the wind-
shield may fog over briefly when the
engine is started. Air conditioning helps
prevent the windows from fogging up.
The cooling function is automatically
switched on when you are using the
AUTO program.

The correct wheels and tires
BMW recommends using only
wheels and tires that have been
tested and approved by BMW for the
particular vehicle model, as otherwise
body contact and serious accidents can
result despite the use of the same nom-
inal size, e.g. due to manufacturing tol-
erances. If non-approved wheels and
tires are used, BMW cannot evaluate
their suitability, and therefore cannot be
held liable for driving safety.<
To maintain good handling characteris-
tics, only use a full set of tires of the
same brand and tread configuration.
After a flat tire, have the previous wheel
and tire combination restored as soon
as possible.
Recommended tire sizes and
brandsFor each tire size, certain tire brands
have been tested, classified as road-
safe and approved by BMW. You can
find out about these from a professional
tire center, preferably your BMW cen-
ter. Observe any country-specific regu-
lations, e.g. on making a corresponding
entry in the vehicle documents.
The factory-approved radial belt tires
are matched to your vehicle and pro-
vide optimum safety and driving com-
fort when used properly.Special characteristics of winter
tiresBMW recommends the use of winter
tires for operation under winter road
conditions. While all-season tires with
M+S designation provide better winter
traction than summer tires, they gener-
ally do not achieve the full performance
of winter tires.Observing speed ratings
Never exceed the maximum
speed for which the winter tires
are rated. Unprofessional attempts by
laymen to service tires can lead to dam-
age and accidents. Have this work per-
formed by skilled professionals only.
The technicians at your BMW center
will be glad to assist you with the
required professional knowledge and
specialized equipment.<
StorageAlways store tires in a cool, dry place.
Store them away from light whenever
possible. Protect the tires against con-
tact with oil, grease and fuel. Do not
exceed the maximum tire inflation pres-
sures specified on the tire sidewall.

Adding engine oilOnly add engine oil when the oil level
has dropped to just above the lower
mark on the dipstick.
Do not fill beyond the upper mark on
the dipstick. Excess oil will damage the
engine.
Before checking the engine oil level
after topping up, restart the engine and
allow it to run to obtain a correct dis-
play. Then proceed as described under
Checking the oil level.
Continuous exposure to used oil
has caused cancer in laboratory
testing. For this reason, thoroughly
wash any areas of skin that come into
contact with oil using soap and water.
Store oils, grease and similar materials
so that they are inaccessible to chil-
dren. Comply with warning labels and
information on containers.<
Comply with the applicable envi-
ronmental laws regulating the dis-
posal of used oil.<
Recommendation: have the oil changed
by your BMW center.
Specified engine oilsThe quality of the engine oil is
extremely important for the function
and life of an engine. Based on exten-
sive testing, BMW has approved only
certain grades of engine oil.
Use only oils approved for your vehicle
model.
Ask your BMW center for details
concerning oils that have been
approved. You can also call BMW of
North America toll-free at 1-800-831-
1117 or visit this website:
www.bmwusa.com to obtain this infor-
mation.<
BMW engines are designed to
operate without oil additives; the
use of additives could even lead to
damage in some cases.<
Alternative oil typesIf a High Performance Synthetic Oil
approved by BMW should be unavail-
able, you may use small volumes of
other synthetic oils for topping up
between oil changes. The following
data must appear on the packaging:
>Viscosity
preferred: SAE 10W-60
alternative: SAE 5W-40 or
SAE 10W-40
>Specifications
preferred: API SJ/CF
alternative: API SJ – also SK, SL, S
etc.

Low ambient temperaturesThe oils used by BMW at the factory for
your vehicle model can be used at virtu-
ally any ambient temperature.
However, if the vehicle is exposed to
temperatures below –47/–206 for
extended periods, please have your
BMW center recommend a suitable oil.
Coolant
Do not open the cooling system
when the engine is hot. If you do,
escaping coolant can cause burns.<
Coolant consists of water and coolant
additives. Not all commercially available
additives are suitable for your BMW.
Your BMW center knows which addi-
tives are appropriate.
Only use approved additives, as
the engine could otherwise be
damaged. The additives are hazardous
to health.<
Comply with the applicable envi-
ronmental laws regulating
the disposal of coolant additives.<
Checking the coolant level1. The engine must be at ambient tem-
perature
2. Open the cap for the expansion tank
by turning it slightly counterclock-
wise to allow accumulated pressure
to escape. Then open
3. The coolant level is correct when the
upper end of the red float is even
with the upper edge of the filler neck,
refer to the arrow in the illustration or
to the schematic diagram next to the
filler neck
4. If necessary, slowly add coolant until
the correct level is reached; do not
overfill
5. Close the cap by turning until it is
well tight
6. Have the cause for the coolant loss
removed as soon as possible.

maintenance and repair.
Be sure that all maintenance work is
recorded in the Service and Warranty
Information Booklet for US models, or
in the Warranty and Service Guide
Booklet for Canadian models. These
entries are your verification for the reg-
ular maintenance of your vehicle and
are required for the performance of
warranty repairs.<

OBD interface socketThe Onboard Diagnostic OBD interface
socket is located on the left of the
driver's side under the instrument panel
and under a cover.
The cover has the letters OBD on it.
The purpose of the OBD system is to
ensure proper operation of the emis-
sion control system for the vehicle"s
lifetime. The system monitors emission-
related components and systems for
deterioriation and malfunction.
An illuminated lamp informs you
of the need for service, not of
the need to stop the vehicle.
However, the systems should be
checked by your BMW center at the
earliest possible opportunity.
Display in Canadian models for
the malfunction described
above.
Under certain conditions, the indicator
will blink or flash. This indicates a rather
severe level of engine misfire. When
this occurs, you should reduce speed
and consult the nearest BMW center as
soon as possible. Severe engine misfire
over only a short period of time can
seriously damage emission control
components, especially the catalytic
converter.
When the fuel filler cap is not
properly tightened, the OBD sys-
tem can detect the vapor leak and the
indicator will light up. If the filler cap is
subsequently tightened, the indicator
should go out within a few days.<
Event data recordersYour vehicle may be equipped with one
or more sensing and diagnostic mod-
ules or a recording device capable of
recording or transmitting certain vehicle
data or information. In addition, if you
have a Subscription Service Agreement
for the BMW Assist system, certain
vehicle information may be transmitted
or recorded in order to provide such
services.
