Computer

Mode selectionFrom ignition key position 1 on, you can
use the button in the turn signal lever to
retrieve information from the computer
for display in the instrument cluster. By
pressing the button briefly in the direc-
tion of the steering column, you can call
up a new function for display.
The displays appear in the following
order:
Time of day, outside temperature,
average fuel consumption, cruising
range, average vehicle speed.
From ignition key position 1 on, the last
active setting is displayed.
Outside temperature You can change the units of measure
(6/7) for the outside temperature
display by pressing the right-hand reset
button in the instrument cluster while
the temperature display is active.
Ice warning If the outside temperature drops to
about 37.5 7 (+3 6), then the
computer will automatically switch to
show the outside temperature. In addi-
tion, a signal sounds as a warning and
the display flashes for a brief period.
This warning will repeat itself whenever
the temperature has climbed to at least
43 7 (+6 6) since the last warning,
and has then dropped back to 37.5 7
(+3 6).
Ice warnings do not exclude the
possibility that surface ice can still
occur at temperatures above 37.5 7
(+3 6), e. g. on bridges and shady
roads.<

Computer Average fuel consumption If you continue to hold the button on the
turn signal lever, the average fuel
consumption last displayed is recalcu-
lated from that point in time.
Cruising range The computer bases its calculations
of the cruising range on the previous
driving style.
Average speed If you continue to hold the button on the
turn signal lever, the average speed last
displayed is recalculated from that
point in time.
Any time spent when the vehicle is
stationary and the engine is shut off is
ignored for the calculation.

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).<

Automatic climate control Air supply (fan)
By pressing the left or right half
of the button, you can vary the
air supply. By doing this, you switch off
the automatic control of the air supply.
Nevertheless, the automatic air distri-
bution remains unchanged.
When you set the lowest blower speed
by pressing the left half of the 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.
Defrosting the windows and
removing condensation
This program quickly removes
ice and condensation from the
windshield and side windows.
Air conditioner
The air is cooled and dehumidi-
fied and – depending on the
temperature setting – rewarmed when
the air conditioner system is switched
on.
Depending on the weather, the wind-
shield may fog over briefly when the
engine is started.
Use the button to switch the air condi-
tioner off at outside temperatures
below approx. 41 7(+5 6). This will
help to prevent the windows from
fogging over.
If the windows fog over after switching
the air conditioner off, switch it back
on.
Condensation forms in the air
conditioner system during opera-
tion, that then exits under the vehicle.
Traces of condensed water of this kind
are thus normal.<
Automatic recirculated air control
(AUC)
If there are unpleasant odors or
pollutants in the outside air, you
can temporarily block the airflow from
the outside. The system then recircu-
lates the air already within the vehicle.
By repeated actuation of the button,
you can select one of three different
operation modes.
>Indicator lamps off: outside air always
flowing into the vehicle
>Left-hand indicator lamp on – Auto-
matic mode: the system detects
pollutants in the outside air and
responds by deactivating the outside
airflow as required. The system then
recirculates the air already 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.

The BMW Maintenance System has
been designed as a reliable means of
providing maximum driving and oper-
ating safety – and as cost-effectively as
possible for you.
Please keep in mind that regular main-
tenance is not only necessary for the
safety of your vehicle, but also plays a
significant role in maintaining the resale
value of the vehicle. Service Interval DisplayAdvanced technology is employed to
calculate the optimal maintenance
intervals. These are then indicated in
the Service Interval Display. While
conventional systems rely solely on
distance traveled to determine when
service is due, the BMW Maintenance
System considers the actual conditions
under which the vehicle operates,
because miles can be traveled in many
different ways:
From the point of view of maintenance,
for example, 62,000 miles (100,000 km)
short-distance driving are not equal to
the same 62,000 miles (100,000 km) of
long-distance travel.
The BMW Maintenance System
includes the Engine Oil Service and
Inspections I and II.
Determining the maintenance intervals
according to the actual use of the
vehicle covers every kind of operating
situation. Those who are outright
"Sunday drivers," driving fewer than
6,000 miles (10,000 km) per year –
should, nevertheless have their oil
changed every 2 years at the most, no
matter what the Service Interval Display
indicates, since engine oil breaks down
over time, regardless of use. Service and Warranty Information
Booklet (US models)/Warranty
and Service Guide Booklet (Cana-
dian models)For additional information on required
maintenance intervals and procedures,
please refer to the Service and Warranty Information Booklet
(US models), or the Warranty and
Service Guide Booklet (Canadian
models).
As a precaution against rust, it is advis-
able to have the body checked for
damage from rocks or gravel at the
same time, depending upon operating
conditions.
Have your BMW center perform
maintenance and repair.
Your BMW center is always informed on
the latest maintenance work and repair
techniques and equipped with the
required special tools. In addition,
checking parts known from experience
to be subject to wear is a permanent
part of the maintenance specifications.
Be sure that all maintenance work is
confirmed in the Service and Warranty
Information Booklet (US models), or in
the Warranty and Service Guide
Booklet (Canadian models). These
entries are your verification for the
regular maintenance of your vehicle
and are required for the performance of
warranty repairs.<

Technical modifications California Proposition 65 WarningAny BMW center will be happy to
advise you concerning the advisability,
legal implications and factory recom-
mendations for technical modifications
to the vehicle. For this purpose, the
BMW center will require the Vehicle
Identification Number and, in some
cases, the engine number as well. Light-emitting diodes (LEDs)Light-emitting diodes installed behind
translucent lenses serve as the light
source for many of the controls and
displays in your vehicle. The concept
behind their operation is related to that
employed for lasers, and they are offi-
cially designated as Class 1 light-emit-
ting diodes.
Do not remove the protective lens
and avoid staring directly at the
unfiltered beam for extended periods
(several hours). To do so could result in
inflammation of the iris.<
California laws require us to state the
following warning:
Engine exhaust, some of its
constituents, and certain vehicle
components contain or emit chemicals
known to the State of California to
cause cancer and birth defects or other
reproductive harm.<

BatteryCharging the battery Charge the battery in the vehicle only
when the engine is not running.
Before doing any work on the
electrical system, be sure to
disconnect the cable from the battery's
negative terminal. Failure to do so can
result in short-circuits, a fire or personal
injury.<
If you plan to park the vehicle for longer
than 4 weeks, disconnect the battery
from the vehicle electrical system by
disconnecting the cable at the negative
terminal. Then recharge the battery with
an appropriate battery charger.
If the vehicle is parked for more than
12 weeks, remove the battery, recharge
it and store it in a cool yet frost- and
dust-free area. During storage, have the
battery recharged every 3 months.
Also, recharge the battery before it is
reinstalled. If this is not done, the
battery will not be serviceable. Every
time the battery is discharged, espe-
cially over extended periods, its service
life is reduced.
Return used batteries to a recy-
cling point or your BMW center.
Maintain the battery in an upright posi-
tion for transport and storage. Secure
the battery to prevent it from tilting
during transport.<
Storage periods during which the
battery is disconnected are not
taken into consideration by the Service
Interval Display for changing the brake
fluid.
For this reason, be sure that the brake
fluid is changed every two years,
regardless of the information displayed.
Comply with the information on this
subject on page 130.<
