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.<Automatic air distribution and
supply
The AUTO program adjusts the
air distribution and the air sup-
ply for you and in addition adapts the
temperature to external influences –
summer, winter – to meet preferences
you can specify.
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 6/7 of
the display, refer to page 80.
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.
Condensation forms during opera-
tion of the air conditioning system,
which then exits under the vehicle.
Traces of condensed water of this kind
are thus normal.<
Automatic climate control

95
Outside air/Automatic
recirculated-air control (AUC)/
Recirculated air
You can respond to unpleasant
external odors or pollutants by
temporarily stopping the flow of outside
air. The system then recirculates the air
currently within the vehicle.
By repeatedly pressing the button, you
can select one of three different operat-
ing modes.
>Indicator lamps off: outside air always
flowing into the vehicle
>Left-hand indicator lamp on – auto-
matic mode: the system detects pol-
lutants in the outside air and
responds by deactivating the outside
airflow as required. The system then
recirculates the air currently within
the vehicle.
Depending on air quality require-
ments, the system automatically
switches between outside air supply
and recirculation of the air already
within the vehicle
>Right-hand indicator lamp on: the
flow of outside air is permanently
blocked. The system recirculates the
air already within the vehicle.
If the windows fog over in the
recirculated-air mode, switch the
recirculated-air mode off and increase
the air supply as required.<
Rear window defroster
When the rear window defroster
is activated, the indicator lamp
comes on. The rear window defroster
switches off automatically.
You can have your vehicle pro-
grammed in such a way that the
rear window defroster switches on
automatically. This occurs within 5 min-
utes after starting the engine when out-
side temperatures are below approx.
397/+46.<
Draft-free ventilationYou can adjust the blower controls for
the upper body area to obtain the opti-
mum airflow rates and directions for
your personal requirements:
1Rotary dials for infinitely variable
opening and closing of the vents
2Lever for adjusting airflow direction
3With the rotary dial you can adjust the
temperature of the outgoing air:
>Turn toward blue – colder
>Turn toward red – warmer

General driving notes
Brakes: do not rest your foot on
the brake pedal while driving.
Even light but consistent pedal pres-
sure can lead to high temperatures,
brake wear and possibly even brake
failure.
Hydroplaning: when driving on wet or
slushy roads, reduce road speed. If you
do not, a wedge of water can form
between tires and road surface. This
phenomenon is referred to as hydro-
planing, and can lead to partial or com-
plete loss of traction, vehicle control
and braking effectiveness.
Driving through water: do not drive
through water on the road if it is deeper
than 1 ft/30 cm, and then only at walk-
ing speed. Otherwise, the vehicle's
engine, the electrical systems and the
transmission may be damaged.
Rear parcel tray: never use it to store
heavy or hard objects; otherwise, occu-
pants could be injured if the vehicle is
braked hard.
Clothes hooks: when suspending cloth-
ing from the hooks, be sure that they
will not obstruct the driver's vision. Do
not hang heavy objects on the hooks. If
you do so, they could cause personal
injury during braking or evasive maneu-
vers.<
Portable phone in the vehicleBMW recommends using mobile com-
munications devices, e.g. portable
phones, inside the vehicle with a suit-
able outside antenna. Otherwise, it can-
not be ruled out that the vehicle elec-
tronics and portable phone may
interfere with each other.

Do not drive on a deflated – flat –
tire. A flat tire greatly impairs
steering and braking response, and can
lead to complete loss of control over
the vehicle.
Avoid overloading the vehicle so that
the permitted load on the tires is not
exceeded. Overloading can lead to
overheating and internal tire damage.
This can result in a sudden loss of tire
inflation pressure.
Unusual vibrations encountered during
normal vehicle operation can indicate
tire failure or some other vehicle defect.
This type of problem can be caused by
contact with curbs, etc. This is also true
for irregularities in the vehicle's han-
dling characteristics, such as a pro-
nounced tendency to pull to the left or
right. Should this occur, respond by
immediately reducing your speed. Pro-
ceed carefully to the nearest BMW cen-
ter or professional tire center, or have
the vehicle towed in to have it, its
wheels or its tires inspected.
Tire damage, up to and including blow-
outs, can endanger the lives of both the
vehicle occupants and other road
users.<
Tire replacementTo maintain good handling and vehicle
response, use only tires of a single
tread configuration from a single manu-
facturer.
Comply with the specified tire inflation
pressures – and be sure to have the
wheel and tire assembly balanced
every time you change a tire or wheel.DOT quality gradesTreadwear
Traction AA A B C
Temperature A B C
All passenger car tires must con-
form to Federal Safety Require-
ments in addition to these grades.<TreadwearThe treadwear grade is a comparative
rating based on the wear rate of the tire
when tested under controlled condi-
tions on a specified government test
course.
For example, a tire graded 150 would
wear one and one-half – 1
1/2 – times as
well on the government course as a tire
graded 100. The relative performance
of tires depends upon the actual condi-
tions of their use, however, and may
depart significantly from the norm due
to variations in driving habits, service
practices and differences in road char-
acteristics and climate.TractionThe traction grades, from highest to
lowest, are AA, A, B and C.
Those grades represent the tire's ability
to stop on wet pavement as measured
under controlled conditions on speci-
fied government test surfaces of
asphalt and concrete. A tire marked C
may have poor traction performance.
The traction grade assigned to
this tire is based on straight-
ahead braking traction tests, and does
not include acceleration, cornering,
hydroplaning, or peak traction charac-
teristics.<TemperatureThe temperature grades are A – the
highest – B and C, representing the
tire's resistance to the generation of
heat and its ability to dissipate heat
when tested under controlled condi-
tions on a specified indoor laboratory
test wheel.
Tire condition
OverviewControlsMaintenanceRepairsDataIndex

116
Sustained high temperature can cause
the material of the tire to degenerate
and reduce tire life, and excessive tem-
perature can lead to sudden tire failure.
The grade C corresponds to a level of
performance which all passenger car
tires must meet under the Federal
Motor Vehicle Safety Standard No. 109.
Grades B and A represent higher levels
of performance on the laboratory test
wheel than the minimum required by
law.
The temperature grade for this tire
is established for a tire that is
properly inflated and not overloaded.
Excessive speed, under-inflation, or
excessive loading, either separately or
in combination, can cause heat buildup
and possible tire failure.<Uniform Tire Quality GradingQuality grades can be found where
applicable on the tire sidewall between
tread shoulder and maximum section
width. For example:
Treadwear 200 Traction AA
Temperature A
Tire ageBMW recommends the replacement of
all tires when the tires are no more than
6 years old, even if a tire life of 10 years
is possible.
The date on which the tire was manu-
factured is indicated by the code on the
sidewall:
DOT ... 3603 indicates that the tire was
manufactured in week 36 of the year
2003.Following wheel/tire changesComply with the specified tire inflation
pressures – and be sure to have the
wheel and tire assembly balanced
every time you change a tire or wheel.
Following wheel and/or tire changes
you will need to reinitialize both the Flat
Tire Monitor and the sequential M gear-
box with Drivelogic, refer to pages 71,
85.

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.
BMW engines are designed to
operate without oil additives; the
use of additives could lead to damage
in some cases. This also applies to the
manual transmission, the differential,
and the power steering system.<
Recommendation: have the oil changed
at your BMW center.
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.<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.<
Alternative oil typesIf a High Performance Synthetic Oil
approved by BMW should be unavail-
able, you may use small volumes of
other 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 add coolant to the cooling
system when the engine is hot. If
you attempt to do so, escaping coolant
can cause burns.
Antifreeze and anti-corrosion agents
are hazardous to health. You should
always store them in their closed origi-
nal containers and in a location inac-
cessible to children. Antifreeze and
anti-corrosion agents are inflammable.
For this reason, do not spill them on hot
engine parts. They could ignite and
cause burns. Comply with the instruc-
tions on the containers.<
Comply with the applicable envi-
ronmental laws regulating the dis-
posal of antifreeze agents with corro-
sion inhibitor.<
Checking the coolant level and
adding coolantCheck the coolant level when the
engine is cold, approx. 687/+206.
1. Open the cap for the expansion tank
by turning it slightly counterclock-
wise to allow accumulated pressure
to escape. Then open
2. The coolant level is correct when the
upper end of the red float is at least
even with the upper edge of the filler
neck – refer to the arrow in the illus-
tration. The end of the float may stick
out by a maximum of 3/4 in / 2 cm –
that is, up to the second mark on the
float. Refer also to the schematic dia-
gram next to the filler neck
