Rear windowTo closeThe handle recesses in the interior trim
panel of the tailgate (arrows) make it
easier to pull the lid down.
Both before starting off and after
completing every journey, check
the rear window or the tailgate to
ensure that it has not been opened
inadvertently.<
To avoid injuries, be sure that the
travel path of the tailgate is clear
when it is closed, as with all closing
procedures.<
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 neces-
sary to operate the vehicle with the tail-
gate or rear window open:
>Close all windows. Shut the sliding/
tilt sunroof
>Sharply increase the air supply for the
air conditioning or automatic climate
control, refer to page 85 or 88.<
To open from outsideSmall items can be loaded or unloaded
quickly if the rear window is opened
separately.
Press the button (arrow): the rear
window opens slightly. It can now be
tilted up.
Opening with the remote control, refer
to page 30.
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
window could be damaged.<

Tips for pleasant drivingUse the automatic system Ð switch on
with AUTO button 7. Select the desired
interior temperature.
Detailed setting options are described
for you in the following section.Automatic air distribution
The AUTO program adjusts the
air distribution and the air
supply 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
program by selecting specific
distribution patterns to suit your
own individual requirements.
While the AUTO program is then deacti-
vated, the automatic airflow control
remains in operation. The system
directs air to the windows , the upper
body and into the footwells . You
can reactivate the automatic air distri-
bution mode 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 72 7
(+22 6) 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 regard-
less of the season. It then maintains this
temperature.
Air supply
By pressing the left or right half
of the button, you can vary the
air supply. This deactivates the auto-
matic control of the air supply, AUTO
disappears from the display panel.
Nevertheless, the automatic air distri-
bution remains unchanged. You can
reactivate the automatic air distribution
mode by selecting the AUTO button.
When you select the lowest blower
speed by pressing 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
automatic 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 Ð depending on the
temperature setting Ð rewarmed.
Depending on the weather, the wind-
shield may fog over briefly when the
engine is started. Switching on the air
conditioning will reduce condensation
forming on the windows.
As the air-conditioning system
operates, condensation forms
within the system.This moisture is
conducted to an outlet beneath the
vehicle; it is thus not unusual for a small
puddle to form under the car while the
system is running.<

Automatic recirculated-air control
(AUC)
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 Ð 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 fog over in the
recirculated-air mode, switch the
recirculated-air mode off and increase
the air supply as required.<
Rear window defroster
When the rear window defroster
is activated, the indicator lamp
comes on. The rear window defroster
switches off automatically.
At outside temperatures colder
than approx. 39 7 (+4 6) the
rear window defroster automatically
assumes operation within 5 minutes
after the engine is started.<
Draft-free ventilationYou can adjust the blower controls for
the upper body area to obtain the
optimum airflow rates and directions for
your personal requirements:
1 Rotary dials for infinitely-variable
opening and closing of the vent
outlets
2 Selector levers for airflow direction
3 Rotary dial 3 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
filter as a standard part of your sched-
uled maintenance. A substantial reduc-
tion in airflow indicates that the filter
needs to be replaced before scheduled
maintenance.
Harman Kardon premium sound
systemPress the button to activate and deacti-
vate the acoustic enhancement.
The system creates the acoustic
impression of a much larger passenger
compartment accompanied by
improved stereophonic sound at all
seating positions.
The system responds to poor reception
conditions by repeatedly alternating
between the stereo and monophonic
modes. You should then switch the
system off.

Tire condition Tire replacementTire damage (up to and including
sudden and complete air loss) can
endanger the lives of both the vehicle
occupants and other road users. 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 vehicle tires must
conform to Federal Safety
Requirements in addition to these
grades.< Tread wearThe tread wear grade is a comparative
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 g) 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.< TemperatureThe temperature grades are A (the
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
temperature can lead to sudden tire
failure. The grade C corresponds to a
level of performance which all
passenger vehicle tires must meet
