Always drive with both the tailgate
and the rear window securely
closed, as exhaust gases might other-
wise be drawn into the interior of the
vehicle.
<
Should it be absolutely necessary to
operate the vehicle with the tailgate or
rear window open:
1. Close all windows. Shut the slid-
ing/tilt sunroof
2. To increase the quantity of air for the
air conditioner or automatic climate
control system, see page 92 or 96.
To open from the outsideSmall items can be loaded or unloaded
quickly if the rear window is opened
separately.
Press button – see arrow: The rear win-
dow opens slightly. It can now be tilted
up.
Opening with the remote control, refer
to page 32.
Push the window down to close it.
If pointed or sharp-edged objects
could strike the rear window while
driving, be sure to provide protection
around all edges. If you do not do this,
the heating conductors of the rear win-
dow could be damaged.<
Cargo areaLuggage strapsUse the retaining straps on the cargo
area floor to secure smaller items of
luggage.
Movement is reduced when objects are
placed on the straps.
To secure your luggage, use the lug-
gage nets* or flexible straps that you
can attach to the fittings at the inner
corners of the cargo area.
Refer also to Cargo loading on
page 109.

Computer*Mode selectionWith the ignition key in position 1 or
higher, you can call up information from
the computer using the button in the
turn signal lever. By pressing the button
briefly toward the steering column, you
can call up a new function for display.
The displays appear in the following
order:
Time of day, outside temperature, aver-
age fuel consumption, cruising range,
average vehicle speed.
With the ignition key in position 1 or
higher, the last active setting is dis-
played.
Outside temperatureYou can change the units of measure
6/7 for the outside temperature dis-
play by pressing the right-hand reset
button in the instrument cluster while
the temperature display is active. The
units of measure 6/7 in the tempera-
ture display of the automatic climate
control change automatically, refer to
page 96.Ice warningIf the outside temperature drops to
about 37.57/+36, then the computer
will automatically switch to a display of
the outside temperature. In addition, a
signal sounds as a warning and the dis-
play flashes for a brief period.
After giving an ice warning, the
display returns to the previous
setting.<
The ice warning does not alter the
fact that surface ice can form at
temperatures above 37.57/+36, on
bridges or shaded road surfaces, for
instance.<

Tips for pleasant drivingUse the automatic mode by pressing
AUTO button 7. Select an interior tem-
perature that is comfortable for you.
Detailed setting options are described
for you in the following section.
You can make the settings of your
vehicle in such a manner that
when you unlock the vehicle with the
remote control of your personal key,
your own personalized setting for the
automatic climate control is initiated. supply
The AUTO program adjusts the
air distribution and the air sup-
ply for you and in addition adapts the
temperature to external influences –
summer, winter – to meet preferences
you can specify.
Individual air distribution
You can cancel the AUTO pro-
gram by selecting specific dis-
tribution patterns to suit your
own individual requirements.
While the AUTO program is then deacti-
vated, the automatic airflow control
remains in operation. Air flows onto
windows , toward the upper body
, and into the footwell . You can
switch the automatic distribution of air
back on by selecting the AUTO button.Temperature
The interior temperature that
appears in the display panel is a
general figure intended for reference
purposes. We recommend 727/+226
as a comfortable setting, even if the air
conditioning is on. When you start the
vehicle, the system ensures that the
selected temperature is achieved as
quickly as possible regardless of the
season. It then maintains this tempera-
ture.
To select the units of measure 6/7 of
the display, refer to 75.
Air supply/Blower
Press the left or right half of the
button to regulate the air supply.
This deactivates the automatic control
of the air supply, AUTO disappears
from the display panel. Nevertheless,
the automatic air distribution remains
unchanged. You can reactivate the
automatic air distribution mode by
selecting the AUTO button.
When the lowest blower speed is set
and you press the left half of the button,
all of the displays are canceled: the
blower, heating and air conditioning are
switched off. The outside air supply is
blocked. You can reactivate the system
by pressing any button for the auto-
matic climate control.To defrost windows and remove
condensation
This program quickly removes
ice and condensation from the
windshield and the side windows.
Air conditioning
The air is cooled and dehumidi-
fied and – depending on the
temperature setting – rewarmed.
Depending on the weather, the wind-
shield may fog over briefly when the
engine is started. Air conditioning helps
prevent the windows from fogging up.
Condensation forms during opera-
tion of the air conditioning system,
which then exits under the vehicle. It is
thus not unusual for a small puddle to
form under the car while the system is
running.<

Outside air/Automatic
recirculated-air control (AUC)/
Recirculated air
You can respond to unpleasant
external odors or pollutants by
temporarily stopping the flow of outside
air. The system then recirculates the air
currently within the vehicle.
Press the button repeatedly to select
one of three different operating modes.
>Indicator lamps off: outside air supply
is on
>Left indicator lamp on – AUC mode:
the system recognizes pollutants in
the outside air and blocks the flow of
air when necessary. The system then
recirculates the air currently 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 indicator lamp on: the flow of
external air into the vehicle is perma-
nently blocked. The system then
recirculates the air currently within
the vehicle.
If the windows should fog over in
the recirculated-air mode, switch
this mode off and increase the air sup-
ply as required.<
Rear window defroster
When the rear window defroster
is activated, the indicator lamp
comes on. The rear window defroster
switches off automatically.
You can have your vehicle pro-
grammed in such a way that the
rear window defroster switches on
automatically. This occurs within 5 min-
utes after starting the engine when out-
side temperatures are below approx.
397/+46.<
Draft-free ventilationYou can adjust the blower controls for
the upper body area to obtain the opti-
mum airflow rates and directions for
your personal requirements:
1Rotary dials for infinitely variable
opening and closing of the vent out-
lets
2Selector levers for airflow direction
3Rotary dial allows you to control the
temperature of the airflow from these
outlets as desired

Microfilter/activated-charcoal
filterThe built-in microfilter removes dust
and pollen from the incoming air. The
activated-charcoal filter provides addi-
tional protection by filtering gaseous
pollutants from the outside air. Your
BMW center replaces this combined fil-
ter as a standard part of your scheduled
maintenance. A substantial reduction in
airflow indicates that the filter needs to
be replaced before scheduled mainte-
nance.Automatic climate control*

Proceed carefully to the nearest BMW
center or professional tire center, or
have the vehicle towed in to have it, its
wheels or its tires inspected.
Tire damage, up to and including sud-
den and complete air loss, can endan-
ger the lives of both the vehicle occu-
pants and other road users.<
Tire replacementTo maintain good handling and vehicle
response, use only tires of a single
tread configuration from a single manu-
facturer.DOT quality gradesTread wear
Traction AA A B C
Temperature A B C
All passenger car tires must con-
form to Federal Safety Require-
ments in addition to these grades. rating based on the wear rate of the tire
when tested under controlled condi-
tions on a specified government test
course.
For example, a tire graded 150 would
wear one and one-half – 1
1/2 – times as
well on the government course as a tire
graded 100. The relative performance
of tires depends upon the actual condi-
tions of their use, however, and may
depart significantly from the norm due
to variations in driving habits, service
practices and differences in road char-
acteristics and climate.
TractionThe traction grades, from highest to
lowest, are AA, A, B, and C.
Those grades represent the tire's ability
to stop on wet pavement as measured
under controlled conditions on speci-
fied government test surfaces of
asphalt and concrete. A tire marked C
may have poor traction performance.
The traction grade assigned to
this tire is based on straight-
ahead braking traction tests, and does
not include acceleration, cornering,
hydroplaning, or peak traction charac-
teristics. highest – B, and C, representing the
tire's resistance to the generation of
heat and its ability to dissipate heat
when tested under controlled condi-
tions on a specified indoor laboratory
test wheel.
Sustained high temperature can cause
the material of the tire to degenerate
and reduce tire life, and excessive tem-
perature can lead to sudden tire failure.
The grade C corresponds to a level of
performance which all passenger car
