To closeThe handle recesses in the interior trim
panel of the luggage compartment lid
make it easier to pull the lid down.
To avoid injuries, be sure that the
travel path of the luggage com-
partment lid is clear when it is closed,
following the same precautions as with
all closing procedures.<
Operate the vehicle only when the
luggage compartment lid is com-
pletely closed. Otherwise, exhaust
fumes could penetrate the interior of
the vehicle.<
Should it be absolutely necessary to
operate the vehicle with the luggage
compartment lid open, with closed con-
vertible top:
1. Close all windows
2. Greatly increase the quantity of air
from the automatic climate control
system, refer to page 96.
Emergency releaseThis lever releases the luggage com-
partment lid from the luggage compart-
ment's interior.

Tips for pleasant drivingUse the automatic mode – switch on
with AUTO button 6. Select the desired
interior temperature.
Detailed setting options are described
for you in the following sections.
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. The AUTO program adjusts the
air supply and the air distribu-
tion to the windshield and the side win-
dows, towards the upper body and to
the footwells, and in addition adapts
the temperature to external influences:
e.g. summer, winter.
The cooling function is automatically
switched on when you are using the
AUTO program.
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
the windows , toward the upper
body , and into the footwell . You
can reactivate the automatic air supply
by pressing the AUTO button.Temperature
The interior temperature that
appears in the display panel is a
general figure intended for refer-
ence 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 reached as quickly as possible. It
then maintains this temperature,
regardless of the season.
To select the units of measure 7/6
of the display, refer to page 83.
Air supply/Blower
By pressing the upper or lower
button, you can vary the air sup-
ply. This deactivates the auto-
matic air supply – the AUTO display dis-
appears from the panel. Nevertheless,
the automatic air distribution remains
unchanged. You can reactivate the
automatic air supply by pressing the
AUTO button.
When the lowest blower speed is set
and you press the lower 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 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.
The cooling function is automatically
switched on when you are using the
AUTO program.

Condensation forms during opera-
tion of the air conditioning system,
which then exits under the vehicle.
Traces of condensed water of this kind
are thus normal.<
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.
By repeatedly pressing the button, you
can select one of three different operat-
ing modes.
>Indicator lamps off: outside air always
flowing into the vehicle
>Left-hand indicator lamp on – auto-
matic mode: the system detects pol-
lutants in the outside air and
responds by deactivating the outside
airflow as required. The system then
recirculates the air currently 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.
If the windows fog over in the
recirculated-air mode, switch the
recirculated-air mode off and increase
the air supply as required. With the convertible top closed
or with the hardtop* mounted,
press the button. The indicator lamp
remains on. The rear window defroster
switches off automatically after a short
while.
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 opening and closing
the vents at any setting desired
2Lever for adjusting airflow direction
3With the rotary dial, you can add
more or less cool air to the air coming
from the outlets for the upper body
area:
>Turn toward blue – colder
>Turn toward red – warmer.

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 will replace the 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 early.Automatic climate control

General driving notesHot exhaust system
High temperatures occur with
every vehicle equipped with a cat-
alytic converter. Heat shields are
installed adjacent to some sections of
the exhaust system. Never remove
these shields; do not apply undercoat-
ing to their surfaces. When driving,
standing at idle and parking the vehicle,
take care to avoid contact between the
hot exhaust system and flammable
materials, e.g. hay, leaves, grass, etc.
Such contact could lead to a fire,
resulting in serious personal injury and
property damage.<
When the vehicle is parkedCondensation forms in the automatic
climate control system during opera-
tion, which then exits under the vehicle.
Traces of condensed water of this kind
are thus normal.Before driving through a car washFold in the exterior mirrors manually
because they could otherwise be dam-
aged due to the width of the vehicle.
Hydroplaning
When driving on wet or slushy
roads, reduce vehicle speed. If
you do not, a wedge of water may form
between the tires and the road surface.
This phenomenon is referred to as
hydroplaning, and can lead to partial or
complete loss of traction, vehicle con-
trol and braking effectiveness.<
The risk of hydroplaning increases as
the tread depth of the tires decreases,
refer also to Tire tread on page 120.
Driving through water
Do not drive through water on the
road if it is deeper than 1 ft/30 cm,
and then only at walking speed. Other-
wise, the vehicle's engine, the electrical
systems and the transmission may be
damaged.<
Braking safelyYour BMW is equipped with ABS as a
standard feature. If you are in a situa-
tion which requires full braking, it is
best to brake using maximum brake
pressure: panic stop. Since the vehicle
maintains steering responsiveness, you
can avoid possible obstacles with a
minimum of steering effort, despite the
full brake application.
Pulsation at the brake pedal combined
with sounds from the hydraulic circuits
indicates to the driver that ABS is in its
active mode.
Do not drive with your foot resting
on the brake pedal. Otherwise,
even light but consistent pedal pres-
sure can lead to high temperatures,
brake wear and possibly even brake
failure.<
Wet roads:
if the roads are wet or if there is heavy
rain, it is advisable to gently press the
brakes for a brief moment every few
miles/kilometers. Monitor traffic condi-
tions to ensure that this maneuver does
not pose a hazard to you or to other
road users. The heat generated in this
process helps dry the pads and rotors.
Immediate braking force is then avail-
able if necessary.

Tire codeKnowing the tire code on the tire side-
wall makes it easier to correctly choose
and identify your tires.Tire sizeE.g. 205/60 R 15 91 W
205 = Nominal width in mm
60 = Cross-sectional ratio in %
R = Radial belt construction
15 = Rim diameter in inches
91 = Load index, not on ZR tires
W = Speed rating, in front of the R on
ZR tiresSpeed ratingQ = up to 100 mph (160 km/h)
T = up to 118 mph (190 km/h)
H = up to 130 mph (210 km/h)
V = up to 150 mph (240 km/h)
W = up to 167 mph (270 km/h)
Y = up to 186 mph (300 km/h)Tire Identification NumberTires with DOT codes comply with the
guidelines of the U.S. Department of
Transportation.DOT code:
E.g. DOT xxxx xxx 3204
xxxx = Manufacturer's code for tire
brand
xxx = Tire size and tire version
3204 = Tire age
Tire ageThe date on which the tire was manu-
factured is indicated by the code on the
sidewall:
DOT … 3204 indicates that the tire was
manufactured in week 32 of the year
2004.
BMW recommends the replacement of
all tires when they are no more than
6 years old, even if a tire life of 10 years
is possible.Uniform Tire Quality GradingQuality grades can be found where
applicable on the tire sidewall between
tread shoulder and maximum section
width. For example:
Tread wear 200 Traction AA
Temperature ADOT quality gradesTread wearTraction 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.<
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
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.
