Air conditioningDraft-free ventilationYou can adjust the blower controls for
the upper body area to obtain the
optimum airflow rates and directions for
your personal requirements:
1 Rotary dials for infinitely-variable
opening and closing of the vent
outlets
2 Selector levers for airflow direction
3 Rotary dial 3 allows you to control the
temperature of the airflow from these
outlets as desired.
MicrofilterThe built-in microfilter removes dust
and pollen from the incoming air. Your
BMW center will replace it during
routine maintenance. A substantial
reduction in airflow indicates that the
filter needs to be replaced before
scheduled maintenance.

Tips for pleasant drivingUse the automatic system Ð switch on
with AUTO button 7. Select an interior
temperature that is comfortable for you.
Detailed setting options are described
for you in the following section.Automatic air distribution
The AUTO program adjusts the
air distribution and the air
supply 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
program by selecting specific
distribution patterns to suit your
own individual requirements.
While the AUTO program is then deacti-
vated, the automatic airflow control
remains in operation. The system
directs air to the windows , the upper
body and into the footwells . You
can reactivate the automatic air distri-
bution mode by selecting the AUTO
button.
Temperature
The interior temperature that
appears in the display panel is a
general figure intended for reference
purposes. We recommend 72 7
(+22 6) as a comfortable setting, even
if the air conditioning is on. When you
start the vehicle, the system ensures
that the selected temperature is
achieved as quickly as possible regard-
less of the season. It then maintains this
temperature.
Air supply
By pressing the left or right half
of the button, you can vary the
air supply. This deactivates the auto-
matic control of the air supply, AUTO
disappears from the display panel.
Nevertheless, the automatic air distri-
bution remains unchanged. You can
reactivate the automatic air distribution
mode by selecting the AUTO button.
When the lowest blower speed is set
and you press the left half of the button,
all of the displays are canceled: the
blower, heating and air conditioner are
switched off. The outside air supply is
blocked. 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 Ð depending on the
temperature setting Ð rewarmed.
Depending on the weather, the wind-
shield may fog over briefly when the
engine is started. Switching on the air
conditioning will reduce condensation
forming on the windows.
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.<

Microfilter/activated-charcoal
filterThe built-in microfilter removes dust
and pollen from the incoming air. The
activated-charcoal filter provides addi-
tional protection by filtering gaseous
pollutants from the outside air. Your
BMW center replaces this combined
filter as a standard part of your sched-
uled maintenance. A substantial reduc-
tion in airflow indicates that the filter
needs to be replaced before scheduled
maintenance.
To activate, press the button briefly
with ignition key in position 1 or 2.
The illustration depicts the arrangement
of the buttons if the vehicle is fully
equipped. The arrangement may vary,
depending on the equipment actually
installed.
Harman kardon premium sound
systemPress the button to activate and deacti-
vate the acoustic enhancement.
The system creates the acoustic
impression of a much larger passenger
compartment accompanied by
improved stereophonic sound at all
seating positions.
The system responds to poor reception
conditions by repeatedly alternating
between the stereo and monophonic
modes. You should then switch the
system off.

Information for your safetyThe factory-approved radial tires are
matched to the vehicle and have been
selected to provide optimum safety and
driving comfort.
It is not merely the tire's service life, but
also driving comfort and Ð above all else
Ð driving safety that depend on the
condition of the tires and the mainte-
nance of the specified tire inflation
pressure.
Incorrect tire inflation pressure is
a frequent cause of tire damage. It
also significantly influences the road-
holding ability of your BMW.
Be sure to check the tire inflation pres-
sure, including the space-saver spare
tire or the spare tire, on a regular basis,
at least twice a month and before every
extended journey, refer to page 24. If
this is not done, incorrect tire pressures
can cause driving instability and tire
damage, ultimately resulting in acci-
dents.<
Tire tread Ð tire damageInspect your tires frequently for tread
wear, signs of damage and for foreign
objects lodged in the tread. Check the
tread depth.
Tread depth should not be allowed to
go below 0.12 in (3 mm), even though
the legally specified minimum tread
depth is 0.063 in (1.6 mm). Tread wear
indicators (arrow) are embedded in the
base of the tire's tread. Their locations
are indicated by the legend TWI Ð Tread
Wear Indicator Ð at various points on
the tire's shoulder. When the tread
reaches a depth of 0.063 in (1.6 mm),
these indicators appear to signal that
the tires have worn to the minimum
legal level. Below 0.12 in (3 mm) tread
depth, there is an increased risk of
aquaplaning, even at relatively
moderate speeds and with only small
amounts of water on the road.
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 increases the rate at
which damage develops inside the
tires. The ultimate result can assume
the form of a sudden air loss.
Unusual vibrations encountered during
normal vehicle operation can indicate a
flat tire or some other vehicle malfunc-
tion. The type of problem can be
caused by contact with curbs, etc. This
is also true for irregularities in the
vehicle's handling characteristics, such
as a pronounced tendency to pull to the
left or right. Should this occur, respond
by immediately reducing your speed.
Proceed carefully to the nearest BMW
center or professional tire center, or
have the vehicle towed in to have it, its
wheels and tires inspected.

Tire condition Tire replacementTire damage (up to and including
sudden and complete air loss) can
endanger the lives of both the vehicle
occupants and other road users. response, use only tires of a single
tread configuration from a single manu-
facturer.
DOT Quality GradesTread wear
Traction AA A B C
Temperature A B C
All passenger vehicle tires must
conform to Federal Safety
Requirements in addition to these
grades.< Tread wearThe tread wear 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 g) 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.
Sustained high temperature can cause
the material of the tire to degenerate
and reduce tire life, and excessive
temperature can lead to sudden tire
failure. The grade C corresponds to a
level of performance which all
passenger vehicle tires must meet

Winter tiresChoosing the right tireBMW recommends winter tires (M+S
radial tires) for operation under
inclement winter driving conditions.
While all-season tires (M+S designa-
tion) provide better winter traction than
summer tires with the load ratings H, V,
W, Y and ZR, they generally do not
achieve the performance of winter tires.
In the interest of safe tracking and
steering response, install winter tires
made by the same manufacturer having
the same tread configuration on all four
wheels.Never exceed the maximum
speed for which the winter tires
are rated.
Unprofessional attempts by laymen to
service tires can lead to damage and
accidents.
Have this work performed by trained
professionals only. Any BMW center
has the required technical knowledge
and the proper equipment and will be
happy to assist you.<
Tire condition, tire pressureOnce the tire wears to below 0.16 in
(4 mm), winter tires display a percep-
tible decrease in their ability to cope
with winter driving conditions, and
should be replaced in the interest of
safety.
Comply with the specified tire inflation
pressures Ð and be sure to have the
wheel and tire assemblies balanced
every time you change the tires.
StorageAlways store tires in a cool, dry place.
Store them away from light whenever
possible. Protect the tires against
contact with oil, grease and fuel.Snow chains
*
BMW narrow-link snow chains are
intended for mounting on summer or
winter tires in pairs at the rear wheels
only. Comply with all manufacturer's
safety precautions when mounting the
chains.
You cannot mount snow chains on the
following tires:
225/50 R 16 92
225/45 R 17 91
245/40 ZR 17

Engine oilChecking oil level1. Park the vehicle on a level surface
2. Switch the engine off after it has
reached normal operating tempera-
ture
3. After approx. 5 minutes, pull the
dipstick out and wipe it off with a
clean lint-free cloth, paper towel, or
similar material
4. Carefully push the dipstick all the
way into the guide tube and pull it
out again
5. The oil level should be between the
two marks on the dipstick.
As with fuel economy, oil consumption
is directly influenced by your driving
style and vehicle operating conditions.
The oil volume between the two marks
on the dipstick corresponds to approx.
1.1 US quarts (1 liter). Do not fill beyond
the upper mark on the dipstick. Excess
oil will damage the engine.
Adding engine oilWhile you should wait until the level has
dropped to just above the lower mark
before adding oil, you should never
allow the oil level to fall below this
mark.
BMW engines are designed to
operate without oil additives; the
use of additives could lead to damage
in some cases. This is also true for the
manual transmission, the automatic
transmission, the differential, and the
power steering system.<
Recommendation: have the oil changed
at your BMW center.
