ComputerIce warning If the outside temperature drops to
about 37.5 7 (+3 6), then the com-
puter will automatically switch to show
the outside temperature. In addition, a
signal sounds as a warning and the
display flashes for a brief period.
This warning will repeat itself whenever
the temperature climbs to at least 43 7
(+6 6) since the last warning, and has
then drops 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.<
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.46cus009

Tips for pleasant drivingUse the automatic system (switch on
AUTO-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 some-
what 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 102.
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 106) 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 106) 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).<

Air supply

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.
To defrost the windows and to
remove condensation
This program quickly removes
ice and condensation from the
windshield and side windows.
Air conditioner
The air is cooled and dehumidi-
fied and Ð depending on the
temperature setting Ð rewarmed when
the air conditioner 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 up.
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 air supply
from the outside. The system then
recirculates the air already within the
vehicle. By repeated actuation of the
button, you can select one of three
different operation modes.
>Indicator lamps off: fresh air flows
into the vehicle.
>Left-hand indicator lamp on Ð AUC
mode: the system detects pollutants
in the outside air and responds by
deactivating the outside air supply as
required. The system then recircu-
lates the air already within the vehicle.
Depending on the air quality, the
automatic system then switches back
and forth between outside air supply
and recirculation of the air within the
vehicle.
>Right-hand indicator lamp on: the
supply of outside air is permanently
blocked. The system recirculates the
air already within the vehicle.
If the windows fog over in the
recirculated air mode, switch this
mode off and increase the air supply as
required.<

Winter tiresChoosing the right tireBMW recommends winter tires (M+S
radial tires) for driving in adverse winter
road conditions. So-called all-season
tires with the M+S identification mark
do indeed possess better winter trac-
tion than summer tires that have the H,
V, W, Y and ZR speed ratings, but they
generally fail to provide the same levels
of performance as 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.
Mount only winter tires which have
been approved by BMW. Any BMW
center will be glad to provide you with
information on the best winter tires for
every particular driving condition.
Do not exceed specified
maximum speeds
Never exceed the maximum speed
for which the tires are rated.
Unprofessional attempts by laymen to
service tires can lead to damage and
accidents.
Have this work performed by skilled
professionals only. Any BMW center
has the required technical knowledge
and the proper equipment and will be
happy to assist you.<
Tire condition, tire pressureWinter tires display a perceptible loss in
their ability to cope with winter driving
conditions once the tread wears to
below 0.16 in (4 mm), and therefore in
the interest of safety, should be
replaced.
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
*
Use narrow-link BMW snow chains
on
winter tires only in pairs and only on the
rear wheels. Comply with all manufac-
turer's safety precautions when
mounting the chains.

The BMW Maintenance System has
been designed as a reliable means of
providing maximum driving and operat-
ing safety Ð 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 on distance
traveled alone to determine when
service is due, the BMW Maintenance
System has for years considered the 46cus018
actual conditions under which the
vehicle operates, because miles can be
traveled in many different ways:
From a maintenance point of view,
62,000 miles (100,000 km) of short-
distance urban driving are not equiva-
lent to the same distance covered at
moderate speeds in long-distance
highway 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. However, even those who
drive only short distances Ð significantly
less than 6,000 miles (10,000 km) annu-
ally Ð should have the engine oil
changed at least every 2 years, since oil
deteriorates over time, regardless of
use.Service and Warranty Information
Booklet (US models)/Warranty
and Service Guide Booklet
(Canadian models)For additional information on mainte-
nance 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 en-
tries are your verification for the regular
maintenance of your vehicle and are
required for the performance of
warranty repairs.<

Any BMW center will be glad to inform
you of the advisability, legal require-
ments and factory recommendations
regarding technical modifications on
your vehicle. For this purpose, the
BMW center will require the Vehicle
Identification Number and, in some
cases, also the engine number. 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.
Do not remove the protective lens
and avoid staring directly at the
unfiltered beam for extended periods
(several hours), as inflammation of the
iris could result.<
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.<

BatteryRemoval and installation
Do not disconnect the battery
when the engine is running. If you
do so, the ensuing voltage surge will
damage the vehicle's onboard
electronics.
Do not make any modifications in the
wires to the positive terminal. If you do
so, the protective function of the safety
battery terminal is no longer ensured.
Repair and disposal must be performed
by trained technicians only.<
When removing the battery, disconnect
the cable on the negative terminal first,
then the cable on the positive terminal.
Loosen the center adjusting screw on
the battery retaining strap (use the
screwdriver included with the onboard
tool kit) and disconnect the strap.
When installing a battery, connect the
positive terminal first, then connect the
negative terminal.
When installing a battery, be sure
that it is mounted properly and that
the retaining bracket is installed with the
center adjustment screw. If this is not
done, the battery will not be adequately
secured in case of an accident.<
Charging 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
unclamp 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. Have the battery recharged
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
recycling center or your BMW
center. Maintain the battery in an
upright position 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.
Please read the pertinent information
on page 148.<
