For your own safety

Use unleaded gasoline only. Fuels
containing up to and including
10 % ethanol or other oxygenates with
up to 2.8 % oxygen by weight (i.e.
15 % MTBE or 3 % methanol plus an
equivalent amount of co-solvent) will
not void the applicable warranties
respecting defects in materials or work-
manship. Field experience has indi-
cated significant differences in fuel
quality (volatility, composition, addi-
tives, others) among gasolines offered
for sale in the United States and
Canada. The use of poor quality fuels
may result in drivability, starting and
stalling problems especially under
certain environmental conditions, such
as high ambient temperature and high
altitude.
Should you encounter driveability prob-
lems which you suspect could be
related to the fuel you are using, we
recommend that you respond by
switching to a recognized high-quality
brand.
Failure to comply with these recom-
mendations may result in unscheduled
maintenance.
Obey pertinent safety rules when you
are handling gasoline.

Important safety information!
For your own safety, use genuine parts
and accessories approved by BMW.
When you purchase accessories tested
and approved by BMW and Original
BMW Parts, you simultaneously acquire
the assurance that they have been
thoroughly tested by BMW to ensure
optimum performance when installed
on your vehicle.
BMW warrants these parts to be free
from defects in material and workman-
ship.
BMW will not accept any liability for
damages resulting from installation of
parts and accessories not approved by
BMW.
BMW cannot test every product made
by other manufacturers to verify if it can
be used on a BMW safely and without
risk to either the vehicle, its operation,
or its occupants.
Original BMW Parts, BMW Accessories
and other products approved by BMW,
together with professional advice on
using these items, are available from all
BMW centers.

Installation and operation of non-BMW
approved accessories such as alarms,
radios, amplifiers, radar detectors,
wheels, suspension components, brake
dust shields, telephones (including
operation of any portable cellular phone
from within the vehicle without using an
externally mounted antenna) or trans-
ceiver equipment (such as CB, walkie-
talkie, ham radio or similar) may cause
extensive damage to the vehicle,
compromise its safety, interfere with
the vehicle's electrical system or affect
the validity of the BMW Limited
Warranty. See your BMW center for
additional information.

Maintenance, replacement, or
repair of the emission control
devices and systems may be performed
by any automotive repair establishment
or individual using any certified auto-
motive part.

Luggage compartment lidTo closeThe handle recesses (arrows) 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
compartment lid is clear when it is
closed, as with all closing procedures.
Do not drive with the luggage compart-
ment lid open, since exhaust fumes
could penetrate the interior of the
vehicle. Nevertheless, should it be
absolutely necessary to operate the
vehicle with the luggage compartment
lid open (with closed convertible top):
>Close all windows
>Increase the air supply for the air
conditioner or automatic climate
control to a high level, refer to
pages 89, 92.<
Emergency releaseThis lever releases the luggage
compartment lid from the luggage
compartment's interior.

DisplayThe following information or conditions
are displayed from ignition key
position 2 on, until the cause has been
corrected:
1 Inspect the low-beam and high-beam
headlamps, as well as the parking
lamps
2 Door open
3 Luggage compartment lid open
4 Check brake and tail lamps
After completion of a trip and upon
opening the driver's door, an acoustic
signal will sound yet not be displayed,
as a reminder that the low-beam head-
lamps have not been turned off.
If you wish to have a permanent time
display, you can make this adjustment
in the car radio
* display (refer to the

Dynamic Stability Control (DSC)

The concept

DSC maintains vehicle stability, even in
critical driving situations.
The system optimizes vehicle stability
during acceleration and when starting
from a full stop, as well as optimizing
traction. In addition, it also recognizes
unstable driving conditions such as
under- or oversteering on curves, and
keeps the vehicle on a steady course
by using the engine and brake system
to intervene at the different wheels,
doing only what it can within the laws of
physics, of course.
The system starts up automatically
each time you start the engine.The laws of physics cannot be
repealed, even with DSC. The
results of driving irresponsibly rest with
the driver. We therefore urge you to
avoid using the additional safety margin
of the system as an excuse for taking
risks. Do not make any modifications to
the DSC system. Allow only authorized
technicians to perform service proce-
dures on the DSC.<
Indicator lamp
The indicator lamp in the instru-
ment cluster will go out shortly
after the ignition has been
switched on, refer to page 18.
>Indicator lamp flashes: the system is
active and is controlling the drive
torque based on driving conditions
>If the indicator lamp fails to go out
after the engine has been started, or
if it comes on during normal driving
and stays on: the system has been
deactivated via the button or is
defective. You can continue to drive
the vehicle normally, but without
DSC. Please consult your BMW
center for repairs.

Flat Tire MonitorInitializing the systemInitializing is necessary to familiarize the
system with the correct inflation pres-
sure.
Repeat this process after any changes
in tire inflation pressure, tire rotation or
replacement.
1. Check the tire inflation pressure in all
the tires, comparing them with the
inflation pressure table (page 25),
and adjusting their pressure if neces-
sary
2. Turn the ignition key to position 2
3. Press button as long as you need to
until the indicator lamp in the instru-
ment cluster lights up. After a little
while, the indicator lamp will go out
by itself
4. After a few minutes, the Flat Tire
Monitor will accept the current infla-
tion pressure as the value to be
measured against, and from that
point on, can detect and report a flat
tire.
Activating/deactivating the
systemThe system is automatically activated in
ignition key position 2 and conse-
quently is on whenever the vehicle is
operated.
To deactivate the system: tap the
button, the indicator lamp will light up
yellow.
To activate the system: tap the button
again; the indicator lamp goes out.
Deactivate the system when snow
chains are mounted, since false warn-
ings and undetected losses in pressure
are possible under these kinds of
conditions.

Air conditionerAir supply (blower)
You can select blower speeds
from 1 to 4. The heating and
ventilation become more and
more effective as the air
supply settings are increased. In posi-
tion 0, the blower and the heater are
switched off. By using position 0, you
can totally block the air supply by
pressing the button for the recirculated-
air mode.
Temperature
In order to increase the
temperature of the passenger
compartment, turn it to the
right (red). Temperature regu-
lation will keep the interior temperature
you have selected constant.
Air distribution
You can direct air to flow onto
the windows , toward the
upper body and into the
footwell . All intermediate
settings are possible. In the setting,
there is a low flow of air onto the
windows to keep them free of conden-
sation.
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 defroster automatically
assumes operation within 5
minutes after the engine is started at
outside temperatures below 40 7
(4 6).<
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.
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.<
Recirculated-air mode
You can respond to unpleasant
external odors by temporarily
excluding the supply of outside air. 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.

Air conditionerDraft-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 vent outlets through an infinitely
variable range
2 Lever for adjusting 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.
MicrofilterAn microfilter, which traps incoming
dust and pollen, has been installed in
your vehicle. Your BMW center will
replace it during routine maintenance.
A substantial reduction in airflow indi-
cates that the filter needs to be
replaced early.
To defrost windows and remove
condensation1. Set the blower speed control for the
airflow rate to position 4
2. Turn the rotary temperature control
completely to the right (red)
3. Rotary control for air distribution in
position
4. Switch on the rear window defroster
to defrost the rear window.
