The temperature warning device
does nothing to alter the fact that sur-
face ice can still form at temperatures
above 37.5 5F (+36), e.g., on bridges
and on shade-covered road surfaces.c

recirculated air control (AUC)
*
Press the button repeatedly to run
through the following control sequence:
dIndicator lamps off: outside air flow
operational.
dLeft-hand indicator lamp on Ð AUC
mode: the system detects pollutants
in the outside air and responds by
deactivating the outside air flow as
required. The system then recircu-
lates the air currently within the vehi-
cle.
dRight-hand indicator lamp on: the
flow of outside air into the vehicle is
permanently blocked. The system
then recirculates the air currently
within the vehicle.a
If the windshields fog over in circu-
lated air mode, switch off the circulated
air mode/Automatic recirculated air
control and increase the air supply. if
necessary.c
Rear window defrosterBMW Convertible: Heated rear-window
blower.
The rear-window blower is always
switched off with the convertible top
down.
When the hardtop
* is in place, press
the rear-window heating button.
Temperature
This program is designed for
rapid removal of ice and con-
densation from the windshield and side
windows.
The air conditioner cools and
dehumidifies incoming air
before reheating it to the selected tem-
perature.
Depending on the weather, the wind-
shield may fog over briefly when the
engine is started.
Switching off the air conditioner at out-
side temperatures below approx. 41 5F
(56) will prevent the windows from
fogging up.
Frequently switching the air condi-
tioner on and off may also promote the
formation of condensation on the win-
dow surfaces.
b
Condensation forms in the air
conditioner system during operation,
which then exits under the vehicle. It is
not unusual for a small puddle to form
there.c
You can respond to unpleas-
ant odors in the outside air
by temporarily excluding the outside air.
The system then recirculates the air
currently within the vehicle.
A
The indicator lamp comes
on to confirm that the rear
defroster is operating.
The defroster switches off automatically
after approx. 15 minutes.
On both the driver's and the
passenger's side you can
adjust the specific temperature. The fig-
ures in the display provide a general
indication of interior temperature. We
recommend 70 5F (226) as a standard
setting for comfortable travel, both with
and without the air conditioner. When
you start the vehicle, the system
ensures that the selected temperature
is achieved as quickly as possible and
maintained at a constant level by the
control.

Information for your safetyThe factory-approved radial tires have
been selected to provide optimum
safety and driving comfort on your vehi-
cle.
In a very real sense, both tire life and
your own safety are riding on correct
tire specifications and inflation pres-
sures.
Incorrect inflation pressures are a fre-
quent cause of tire damage. To a great
extent it also influences the ability of
your BMW to hold the road.a
Check the tire pressures Ð also in
the spare tire Ð at least every two weeks,
and before every extended trip.
Incorrect inflation pressures can also
lead to tire damage and accidents.c
Tire tread - tire damageInspect your tires frequently for tread
wear, signs of damage and for foreign
objects lodged in the tread. Check the
tread depth.
The tread depth should not be less than
0.12 in (3 mm). Otherwise there is an
increased risk of aquaplaning, even at
relatively moderate speeds and with
only small amounts of water on the
road.
We recommend that you always replace
the tires once the tread wears to 0.12 in
(3 mm). Once the tread has worn to
0.063 in (1.6 mm), tread depth indica-
tors appear.a
Never continue driving on a deflat-
ed (flat) tire. A flat tire greatly impairs
steering and braking response, and can
lead to complete loss of control over the
vehicle.
Avoid overloading the vehicle so that the
permitted load on the tires is not ex-
ceeded. This can cause overheating and
gradual internal damage. The ultimate
result can assume the form of a sudden
air loss.Unusual vibrations encountered during
normal vehicle operation can indicate
tire failure or some other vehicle defect,
as can variations in normal vehicle
response, such as a pronounced ten-
dency to pull to the left or right. Should
this occur, you should respond by
immediately reducing your speed and
carefully proceeding to the nearest
BMW Retailer or professional tire cen-
ter, or having the vehicle towed in to
have it and its tires inspected.
Tire damage (up to and including blow-
outs) can endanger the lives of both the
vehicle occupants and other road
users.c

CareThe appearance and life of the convert-
ible top are highly dependent on its
proper care and operation. You should
pay particular attention to the following
instructions if your care has a light-col-
ored top.
Protect the vehicle from exposure to
intense sunlight whenever possible by
parking it in the shade to prevent the
paint, rubber and fabric-covered parts
from being attacked.
Never fold up the convertible top and
store it in the convertible top compart-
ment when wet, dirty or frozen, as mil-
dew stains and rub spots may result.
To prevent the formation of a fold in the
rear window and mildew stains, do not
leave the top folded up in the convert-
ible top compartment for longer peri-
ods.
If the vehicle is temporarily stored in a
close room, ensure that the top is dry
and provide sufficient ventilation.
Clean off bird droppings immediately,
as they attack the convertible top and
cause the rubber seals to swell due to
their caustic characteristics.Besides water, only treat rubber seals
with talcum powder, rubber care prod-
ucts or silicone spray, particularly when
they feel dry or tend to stick.
Noises, e.g., squeaks, can be elimi-
nated with a lubricant spray.
Never use sharp-edged objects to
clean the rear window of snow and ice.
The use of de-icing spray is not permit-
ted. Due to the danger of damage and
discoloration, do not apply adhesive
tape, stickers etc. to the window or
cover it with plastic film.
The convertible top and its seams may
become leaky as the result of improper
care and cleaning and from the strain of
long use, and depressions and dirt can
result. All warranty claims are void in
these cases. Please take your vehicle to
your BMW Retailer for servicing.
Washing your carYou can wash your BMW Convertible in
automatic car washes. Here preference
should be given to brushless systems.
If a brushless car wash is unavailable
and brush car wash must be used,
modern systems with soft brushes are
preferable. Do not select special wax-
ing programs. The small amount of
beading wax always used in automatic
car washes will not harm your vehicle's
finish.
In the case of more extensive dirt,
which is especially visible on light-col-
ored top materials, clean the top with
the BMW Convertible Cleaning Set.
Please proceed as follows:
Spray the top with the cleaning agent
and then rub with a well-dampened
sponge using circular motions until a
foam develops. Then you can finish
washing the vehicle in an automatic car
wash. After three to five washings the
top should be treated with a special
impregnating spray. Please follow the
instructions on the spray can.

Procedure1 Wheel bolt cover
* removal.
Steel disk wheel: remove wheel cover
by hand. Light-alloy wheel with lug
cap in the shape of a large hexagon
nut: position the hexagon adapter on
the lug bolt cover, apply the lug
wrench and turn it to the left.2 Loosen lug bolts 1/2 turn.
3 Remove the respective cover cap
from the jacking point. Depending on
the vehicle version, remove the pro-
tective cap either by inserting the
screwdriver into the slot and turning
to the left (arrow in left illustration) or
by pressing in the cap on the bottom
(arrow in illustration above).4 Insert the jack all the way into the
support while ensuring that the base
of the jack is securely positioned on
the road surface. Always chock the
wheels to prevent the vehicle from
rolling.
5 Turn the handle to raise the jack until
the wheel is free of the ground.
a
The vehicle jack is designed for
changing tires only. Never use it to raise
another vehicle model or a load of an-
other kind, since that could result in ac-
cidents and personal injury.
Never lie beneath the vehicle when it is
supported by the jack Ð risk of fatal inju-
ry!c
6 Unscrew the lug bolts and remove the
wheel.
