All other setting options for the auto-
matic climate control can be found at
"Settings" using the Control Center, refer to
page107.
The current settings for temperature and air
supply are displayed to you in the status
line of the Control Display.
A description of the Control Center is pro-
vided on page17.<
A congenial climate
Activate the automatic mode using the
AUTO button or "AUTO" in the Control
Center, refer to page107. Select an interior
temperature you find pleasant.
The following section contains more
detailed information on the available set-
ting options.
All of the air conditioning functions,
including Maximum cooling, refer to
page105, and the Rear air conditioner,
refer to page109, are available only when
the engine is running.<
Your vehicle has been designed to
automatically select your personal
climate-control settings whenever you unlock the doors using your individually
programmed remote control.<
Automatic air distribution and supply
The AUTO program adjusts the
airflow and distribution patterns
for you while also using your
preselected temperature setting as the
basis for adjusting the interior climate to
adapt to external influences: summer, win-
ter.
The air conditioner comes on automatically
when you select the AUTO program.

Temperature adjustment
You can turn to select the
desired temperatures for the
driver's and passenger sides.
Your settings appear on the
Control Display's status line.
The figures in the display provide a general
indication of interior temperature. When
you start the vehicle, this system ensures
that the selected temperature is achieved
as quickly as possible. It then maintains this
temperature, regardless of the season.
Defrosting windows and removing
condensation
This program quickly removes
ice and condensation from the
windshield and door windows.
Adjusting air supply manually
You can adjust the air supply by
turning. The automatic air sup-
ply control is operational when-
ever you see your selection rep-
resented by a bar on the
Control Display's status line. The automatic
air distribution remains in operation as
before. You can reactivate the automatic air
supply mode with the AUTO button.
Switching air conditioner mode on
and off manually
The air conditioner cools and
dehumidifies the incoming air
before also reheating it as
required, according to temperature setting.
Depending on the weather, the windshield
may fog over briefly when the engine is
started.
The air conditioner comes on automatically
when you select the AUTO program.
Maximum cooling
This program quickly provides
maximum cooling.
The temperature display reverts
to 607/166 while the system
switches to the recirculated-air mode and
starts to provide maximum air supply through the vent outlets only. For this rea-
son you should ensure that these outlets
are open before selecting this program.
Outside air/AUC Automatic
recirculated-air control/recirculated
air
You can respond to unpleasant
odors or pollutants in the imme-
diate environment by tempo-
rarily suspending the supply of outside air.
The system then recirculates the air cur-
rently within the vehicle. AUC executes this
function automatically.
Press the button repeatedly to run through
the following control sequence:
>Indicator lamps off: outside air flows
into the vehicle
>Left indicator lamp on, AUC mode: the
system detects pollutants in the outside
air and responds by blocking the supply
of outside air when required. The sys-
tem then recirculates the air currently
within the vehicle.
Depending upon air quality, in the auto-
matic mode the system may start to
alternate between its outside-air and
recirculated-air modes
>Right indicator lamp on, recirculated-air
mode: the supply of outside air into the
vehicle is permanently blocked. The
system then recirculates the air cur-
rently within the vehicle.
If condensation starts to form on the
inside window surfaces during opera-
tion in the recirculated-air mode, you
should switch it off while also increasing air
supply as required.<
Residual heat mode
The system uses the warmth
stored in the engine to heat the
interior when the ignition is off,
for instance, while the vehicle
is stopped at a school to pick
up a child.
You can adjust the automatic climate con-
trol's settings when the ignition lock is in
the radio mode. The system blows heated

A congenial climate
106 air into the interior in accordance with the
selected distribution pattern while the igni-
tion is off.
Provided that the engine has warmed
to its normal operating temperature
and the battery is charged, you can use this
function for up to 15 minutes after switch-
ing off the ignition. The LED within the but-
ton lights up to confirm compliance with
both of these conditions.<
Front ventilation
You can adjust the vent outlets for the
upper body to suit your personal require-
ments.
You can use the serrated dials 1 to open
and close the outlets through an infinitely-
variable range, while the serrated dials 2
allow you to adjust the airflow direction.
Ventilation for cooling
A d j u s t t h e v e n t s t o d i r e c t t h e f l o w o f c o o l a i r
in your direction, for instance, if the interior
has become too warm, etc.
Draft-free ventilation
Set the vent outlets so that the air flows
past you and is not directed straight at you.
You can also individually adjust the air
temperature of the air vents for the
upper body area in the Control Center,
refer to page108.
If the ventilation grill is completely closed,
the vehicle interior is ventilated indirectly
by air vents on the upper side of the cock-
pit.<
Ventilation for storage compartment
in front armrest
You can use the serrated dial in the storage
compartment to open and close the vent.
Depending upon the temperatures
selected at the rear dials, high tem-
peratures may occur in the storage com-
partment. Close the vent as required.<
Ventilation in the rear
The serrated dials 1 allow you to open and
close the ventilation outlets through an infi-
nitely-variable range.
You can adjust the airflow direction using
the levers 2.
The serrated dials3
* control the amount of
cooled air in the flow from the vent outlets:
Turn towards blue: colder
Turn towards red: warmer.
This function allows you to make minor
adjustments for maximum comfort while
also letting you vary temperatures within
the storage compartment.

Under the hood
196 1.5 liter. Do not fill beyond the upper mark
on the dipstick. Excess oil can damage the
engine.
Adding engine oil
Wait until the level has dropped to just
above the lower mark or a message
appears in the Check Control before add-
ing oil.
Store oil, grease etc., well out of the
reach of children; always observe all
warning labels on the containers.<
Specified engine oils
The quality of the engine oil selected has
critical significance for the operation and
service life of an engine. BMW approves
only specific oils after confirming their suit-
ability for use in its vehicles with extensive
testing.
Use only approved BMW High Perfor-
mance Synthetic Oil.
If you are unable to obtain BMW High Per-
formance Synthetic Oil, you can add small
amounts of another synthetic oil between
oil changes. Use only oils with the API SH
specification or higher.
Ask your BMW center for details con-
cerning the specific BMW High Per-
formance Synthetic Oil or synthetic oils
which have been approved.<
You can also call BMW of North America
at 1-800-831-1117 or visit this website:
www.bmwusa.com to obtain this informa-
tion.
BMW engines are designed to oper-
ate without additives, and their use
could even lead to damage in some
cases.<
Viscosity ratings
Viscosity is the oil flow rating as defined in
SAE classes.
The selection of the correct SAE class
depends on the climatic conditions in the
area where you typically drive your BMW.
Approved oils are in SAE classes
5W-40 and 5W-30.<
These oils may be used for driving in all
ambient temperatures.
Coolant
Do not add coolant to the cooling sys-
tem when the engine is hot. Escaping
coolant can cause burns.<
Coolant consists of water and the addition
of antifreeze and anticorrosion agent. Not
all commercially available additives are
suitable for your BMW. Ask your BMW cen-
ter for suitable additives.
Only use suitable additives, as other-
wise engine damage may result. The
additives present a health hazard; observe
the instructions on the containers.<
Always observe all applicable rules
and regulations for environmental
protection when disposing of used anti-
freeze and anticorrosion agents.<
Checking coolant level
1.The engine must be at ambient temper-
ature
2.Turn the cap of the expansion tank
counterclockwise to allow any accumu-
lated pressure to escape, then continue
turning to open
3.The coolant level is correct when the
coolant extends to between the MIN
and MAX marks on the filler neck, refer
to the diagram adjacent to the filler neck
