Air conditionerDraft-free ventilation You can adjust the air outlets for the
upper body area to select the optimum
air flow rates and directions for your
personal requirements:
Use rotary dials 1 to open and close the
air outlets through an infinitely-variable
range. You can adjust the direction of
the air flow with levers 2.
Set the outlets so that the air flows past
you and is not directed straight at you.
Rotary dial 3 allows you to mix the air
from the outlets for your upper body by
warming or cooling the air as desired.460de040
Microfilter An activated-charcoal microfilter, which
traps incoming dust and pollen, has
been installed in your vehicle. Your
BMW center will replace it during regu-
larly scheduled maintenance. A
substantial reduction in air supply indi-
cates that the filter must be replaced
before normal maintenance.
For additional details on the filter
change, refer to page 166.

Tips for pleasant drivingUse the automatic system (switch on
AUTO Ð button 7). Select an interior
temperature that is comfortable for you
Ñ e. g. 72 7 (+22 6). Whenever the
outside temperature is above 41 7
(+5 6), you can also use the air condi-
tioner 12. This will dry the air as well
as preventing condensation on the
window surfaces Ð if there are passen-
gers with damp clothing, for example.
Set the air outlets 2 so that the air flows
past you and is not directed straight at
you. Set the rotary dial between the air
outlets 2 for the upper body to a
medium position, since air that is
somewhat cooler promotes driving
without fatigue.
Detailed setting options are described
for you in the following section.
Automatic air distribution
The AUTO program assumes
the adjustment of the air distri-
bution and the air supply for you and in
addition adapts the temperature to
external influences (summer, winter) to
meet preferences you can specify. This
program maintains a comfortable in-car
climate regardless of the season. Select
an interior temperature that is comfort-
able for you Ñ e. g. 72 7 (+22 6). The
temperature selected and AUTO for
the air supply appear in display 10,
refer to the overview on page 96. Open
the air outlets for the upper body area.
Switch on the air conditioner in warm
weather. The maximum cooling
capacity is achieved when you set
rotary dial 3 (refer to page 100) to cold.
Individual air distribution
You can cancel the AUTO
program by selecting specific
distribution patterns to suit your
own individual requirements.
You can direct air to flow onto the
windows , toward the upper body
, and into the footwell .
Temperature
The figures in the display
provide a general indication of
interior temperature. We recommend
72 7 (+22 6) as a comfortable setting,
even if the air conditioner 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.
Set rotary dial 3 (refer to "Draft-free
ventilation" on page 100) to a medium
setting, since air that is somewhat
cooler promotes driving without fatigue.
You can use this setting for mixing air to
make minor comfort modifications.
You can set uncontrolled heater
output up to 90 7 (+32 6). The
air conditioner is at full cooling output
at 60 7 (+16 6).<

Rear window defroster
When the rear window defroster
is activated, the indicator lamp
comes on. The rear window defroster
switches off automatically. Refer to
page 72.
Draft-free ventilation You can adjust the blower controls for
the upper body area to select the
optimum air flow rates and directions
for your personal requirements:
Use rotary dials 1 to open and close the
air outlets through an infinitely-variable
range. You can adjust the direction of
the air flow with levers 2.
Set the outlets so that the air flows past
you and is not directed straight at you.
Rotary dial 3 allows you mix the air from
the outlets for your upper body by
warming or cooling the air as desired.460de040
Microfilter/Activated-charcoal
filterThe microfilter traps incoming dust and
pollen. The activated-charcoal filter
helps clean the incoming outside air of
gaseous pollutants. Your BMW center
will replace this combined filter during
the regularly scheduled maintenance. A
substantial reduction in air supply indi-
cates that the filter must be replaced
before normal maintenance.
For further information about filter
replacement, refer to page 166.

Disc brakesDisc brakes furnish optimum decelera-
tion and braking control and greater
fade resistance under heavy use.
When the vehicle is driven only occa-
sionally, during extended periods when
the vehicle is not used at all, and in
operating conditions where brake appli-
cations are less frequent, there is an
increased tendency for corrosion of the
discs and accumulation of contamina-
tion on the brake pads. This occurs
because the minimal pressure that must
be exerted by the pads to clean the
discs by brake applications is not
reached.
If the brake discs are corroded, they will
tend to respond to braking with a
pulsating effect that even extended
brake applications will fail to cure.
For your own safety: use only
brake pads that BMW has
approved for your particular vehicle
model. BMW cannot evaluate non-
approved brake pads to determine if
they are suited for use, and therefore
cannot ensure the operating safety of
the vehicle if they are installed.<
Driving notesWhen driving in wet conditions and in
heavy rain, it is effective to apply light
pressure to the brakes every few miles
or kilometers. Be aware of traffic condi-
tions to ensure that this maneuver does
not endanger other road users. The
heat which is generated by the brake
applications helps to dry the brake
pads and discs.
Maximum braking force is obtained
while the wheels are not locked, but
rather when they are still barely turning
immediately prior to locking. ABS main-
tains this state automatically. If the
antilock brake system ever fails, you
should revert to pumping the brakes
(refer to page 120).
Extended or steep mountain descents
should be driven in the gear in which
only minimal periodic brake applica-
tions is required. This avoids excessive
strain on the brakes and possible
impairment of the braking effect.
You can further increase the engine's
braking effect by selecting a lower gear,
downshifting as far as first gear.
When driving a vehicle with automatic
transmission, you can still downshift
into first gear. Refer to page 67.If engine braking should prove to be
inadequate, you should still avoid
extended, continuous braking. Instead
of maintaining low to moderate pres-
sure over an extended period of time,
you should decelerate by applying
more substantial pressure to the brake
pedal (watch for following traffic),
releasing the pedal, and then repeating
the application (staggered braking). The
cooling phases between active braking
intervals prevent the brakes from over-
heating, thus ensuring that full braking
capacity remains available at all times.
Do not coast with the clutch
depressed or with the shift lever
or selector lever in Neutral. Do not drive
with the engine shut off. The engine
provides no braking effect when the
clutch is depressed or the transmission
is in Neutral, and there is no power-
assist for braking or steering when the
engine is not running. Never allow floor
mats, carpets or any other objects to
protrude into the area around the brake,
clutch or accelerator pedals, which can
obstruct pedal travel.<

Engine oil Coolant
Always observe all environmental
protection laws when disposing of
used oil.<
Recommendation: have the oil changed
by your BMW center only.
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.
Always store oils, grease and similar
materials so that they are inaccessible
to children. Comply with warning labels
and information on containers.<
Do not add coolant to the cooling
system when the engine is hot. If
you attempt to do so, escaping coolant
can cause burns.
To avoid the possibility of damage later
on, never use anything other than fac-
tory-approved, nitrite and amino-free
extended-duty antifreeze with corrosion
inhibitor. Your BMW center is familiar
with the official specifications.
Antifreeze and anticorrosion agents are
hazardous to health. You should always
store it in its original container and in a
location that is inaccessible to children.
Extended-duty antifreeze with corro-
sion inhibitor contains ethylene glycol, a
flammable substance. For this reason,
do not spill antifreeze with corrosion
inhibitor on hot engine parts. It could
ignite and cause burns.<
Comply with the applicable envi-
ronmental laws regulating the dis-
posal of extended-duty antifreeze with
corrosion inhibitor.<
Checking coolant levelCorrect coolant level for cold engine
(approx. 68 7 or +20 6):
Unscrew the cap from the expansion
tank.
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 illustra-
tion), but no more than 0.8 in (2 cm)
above it Ð that is, up to the second mark
on the float (refer also to the schematic
diagram next to the filler neck).46cde036
