2001 BMW M3 CONVERTIBLE cooling

Automatic climate controlTips for pleasant drivingUse the automatic system (switch on
AUTO – button 7).
>Select an interior temperature that is
comfortable for you — e. g. 72 7
(+22 6).
>Whenever the outside temperature is
above 41 7 (+5 6), you can also
use the air conditioner 12. This will
dry the air as well as preventing
condensation on the window
surfaces – if there are passengers
with damp clothing, for example.
>Set the 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 sections.
Your vehicle is set in such a
manner that, when you unlock the
vehicle with your individualized remote
control, your own personalized setting
for the automatic climate control is initi-
ated.<
Automatic air distribution
The automatic program will take
over
>automatically distributing the air
supply to the vents, as well as
>automatically adjusting the amount of
incoming air.
It will adapt to the settings you have
made for the temperature that you want
in the passenger compartment – taking
outside influences into account
(summer, winter) – and will privide you
with a comfortable climate in the
vehicle at any time of the year.
>Select an interior temperature that is
comfortable for you — e. g. 72 7
(+22 6). The temperature selected
and AUTO for air supply will
appear in display 10. Refer to the
overview on page 88
>Open up the vents for the upper body
>Switch on the air conditioner in warm
weather. The maximum cooling
capacity is achieved when you set
rotary dial 3 (refer to page 92) 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 92) 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).<

Coolant
Do not add coolant to the cooling
system when the engine is hot. If
you do, escaping coolant can cause
scalds.
To avoid the possibility of damage later
on, never use anything other than
factory-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 which is out of reach of chil-
dren. Extended-duty antifreeze with
corrosion inhibitor contains ethylene
glycol, a flammable substance. For this
reason, do not spill long-life antifreeze
with corrosion inhibitor on hot engine
parts. It could catch fire and cause
serious burns.<
Checking the coolant level and
adding coolant

Check the coolant level when the
engine is cold (approx. 68 7 or
+20 6). The coolant gauge needle in
the instrument cluster must be located
in the blue field; otherwise you could be
scalded when adding more fluid.
1 Open the cap for the expansion tank
by turning it slightly counterclockwise
to allow accumulated pressure to
escape. Then open.
2 The coolant level is correct whenever
the upper end of the red float rod is
aligned with the upper edge of the
filler neck (refer to the arrow in the
illustration and the schematic
diagram next to the filler neck as
well).
3 If necessary, add coolant. If the
coolant is low, slowly add coolant
until the correct level is reached – do
not overfill.
The coolant is a mixture of water and
extended-duty antifreeze with corrosion
inhibitor. Always maintain the pres-
cribed all-season 50:50 mixture ratio for
year-round protection against internal
corrosion. No other additives are
required. Change the coolantReplace the coolant every three years.
Comply with the applicable envi-
ronmental laws regulating the
disposal of extended-duty antifreeze
with corrosion inhibitor.<
