Air conditioner
The air is cooled and dehumidi-
fied and Ð depending on the
temperature setting Ð 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.
Window mist will be reduced by
switching on the air conditioner.
Condensation forms in the air
conditioner system during opera-
tion, which 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 currently within the vehicle.
By repeatedly pressing the button, you
can select one of three different oper-
ating modes.
>Indicator lamps off: outside air always
flowing into the vehicle
>Left-hand indicator lamp on Ð 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 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 off and increase the air
supply as required.<
Rear window defroster
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.
The rear window defroster auto-
matically assumes operation
within 5 minutes after the engine is
started at outside temperatures below
40 7 (4 6).<

Draft-free ventilation You can adjust the blower controls for
the upper body area to select the
optimum airflow rates and directions for
your personal requirements:
1 Rotary dials for opening and closing
the vents at any setting desired
2 Selector lever for airflow direction
3 With the rotary dial you can adjust the
temperature of the outgoing air.
>Turn toward blue Ð colder
>Turn toward red Ð 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.

To openPull the handle. The glove compartment
will light up.To closeFold up cover.
To prevent injury in the event of an
accident, close the glove
compartment immediately after use.< To lockLock with one of the master keys. A
master key can also be used for
unlocking.
If you turn over only your door key
for valet parking, for example
(refer to page 28), access to the glove
compartment and the luggage
compartment lid is not possible.<

Ashtray, front Ashtray, rear To emptyPress on the edge of the open cover
(arrow): you can now pull the ashtray
upward for removal.Extinguishing cigarettesTap off the ash and gently press the tip
into the funnel.
Cigarette lighterPress the lighter 1 in. As soon as the
lighter jumps back out, it can be
removed.
Hold or touch the hot cigarette
lighter by the knob only. Holding
or touching it in other areas could result
in burns.
The cigarette lighter remains opera-
tional when the ignition key has been
removed. For this reason, children
should never be left in the vehicle unat-
tended.< Cigarette lighter socketIt can be used for attaching power
supplies for flashlights, car vacuum
cleaners and other similar appliances
up to a rating of approx. 200 watts at
12 volts. Avoid damaging the socket
due to inserting plugs of different
shapes or sizes.
To emptyPress on the edge of the raised cover in
the opening direction (arrow). You can
now pull the ashtray upward for
removal.

5. Secure the cover panel with the
magnetic retainer on the rear wall
and pull out the ski bag.
Securing the load
Secure the bag's contents by
tightening down the retaining
strap at the buckle.<
Please be sure that the skis are clean
before loading them into the bag. Be
careful to avoid damage from sharp
edges.
Storing the ski bagTo store the ski bag, perform the above
steps in reverse sequence.
When reattaching the center
piece, guide both bars into the
guide and press the center piece back
into place. Secure the safety belts in
their holders again.<

Cargo loading Roof-mounted luggage rack for the hardtop

Securing the cargo in the luggage
compartment >Secure small, light items with a
luggage compartment net
* or elastic
straps, refer to page 35
>For large, heavy pieces, see your
BMW center for load-securing
devices
*. Lashing eyes (arrow) are
provided at the corners of the
luggage compartment for attaching
these load-securing devices.
Comply with the information enclosed
with the load-securing devices.
A special luggage system is available
as an option for your BMW. Please
observe the precautions included with
the installation instructions.Mounting pointsAccess to the mounting points:
To fold up the cover (arrow), please use
the tool which is provided with the
luggage system.Loading and driving notesBecause roof racks raise the center of
gravity of the vehicle when loaded, they
exercise a major effect on its handling
and steering response.
When loading, be sure to remember not
to exceed the approved roof weight or
the approved gross vehicle weight or
the axle loads. You will find the specifi-
cations under "Technical Data" on
page 146.
Make sure that the load is not too bulky,
and attempt to distribute it evenly.
Always load the heaviest pieces first (on
the bottom). Make sure that no objects
get in the way when the luggage
compartment lid is opening or closing.
When carrying cargo on the roof,
always ensure that it is properly
secured. Loose cargo can shift and
even fly off, posing a serious hazard to
other road users.<
Drive smoothly and avoid sudden
acceleration or braking. Do not corner
at high speeds.

Brakes: do not rest your foot on
the brake pedal while driving.
Even light but consistent pedal pres-
sure can lead to high temperatures,
brake wear and possibly even brake
failure.
Aquaplaning: when driving on wet or
slushy roads, reduce road speed. If you
do not, a wedge of water can form
between tires and road surface. This
phenomenon is referred to as aqua-
planing, or hydroplaning, and can lead
to partial or complete loss of traction,
vehicle control and braking effective-
ness.
Driving through water: do not drive
through water on the road if it is deeper
than 1 foot (30 cm), and then only at
walking speed. Otherwise the vehicle
can sustain damage to the engine, the
electrical systems and the transmis-
sion.<
The conceptThe Antilock Brake System (ABS) keeps
the wheels from locking while braking,
thereby enhancing active driving safety.Braking with ABSIf you are in a situation that requires full
braking, you will exploit the full benefits
of the ABS system if you apply
maximum brake pressure ("panic
stop"). Since the vehicle maintains
steering responsiveness, you can
nevertheless avoid possible obstacles
with a minimum of steering effort.
Pulsation at the brake pedal combines
with sounds from the hydraulic circuits
to indicate to the driver that ABS is in
its active mode.Cornering Brake Control (CBC)CBC is an advanced engineering
design of the ABS. When braking while
cornering at high speed or braking
during high lateral acceleration, or
when braking during a lane change,
vehicle stability is improved and
steering response is enhanced.
Brake fluid level Low brake fluid level in the reservoir
combined with longer than usual pedal
travel may indicate a defect in one of
the brake system's hydraulic circuits.
Proceed to the nearest BMW
center. Higher brake application
pressure may be necessary when stop-
ping, and the vehicle may exhibit a
slight tendency to pull to one side.
Brake distances may even be longer.
Please remember to adapt your driving
style accordingly.<
