Caring for your vehiclePlastic components, vinyl upholstery,
the headliner (with the hardtop
*), lamp
lenses, the clear cover for the instru-
ment cluster and dull black surfaces can
be cleaned with either water and possi-
bly a cleaner designed to be used on
plastic. Do not soak the seats or the
headliner (this applies to the hardtop
*).
Never use solvents such as lacquer thin-
ner, heavy-duty grease remover, fuels,
or similar substances.
Rubber components should be cleaned
with water only; a rubber treatment or
silicone spray may also be applied.
Clean the wiper blades with soapy wa-
ter. The wiper blades should be re-
placed twice a year – before and after
winter. This is especially important for
vehicles with a rain sensor
*.
Use only wiper blades approved
by BMW.<
Do not remove safety belts to clean
them. Clean them with mild soapy wa-
ter only. Do not use chemicals or dry
cleaners to clean safety belts, since this
could damage the belt fabric.
After cleaning, never allow the inertia
reel to retract the belts until they are
completely dry. Dirty safety belts pre-
vent the inertia reel mechanism from
retracting the strap properly, and thus
constitute a safety hazard.
Heavily soiled floor carpets and mats
*
can be cleaned with an interior cleaner.
The floor mats can be removed from
the vehicle for cleaning.
Use only a damp cloth to clean trim
panels made of real wood
* and other
parts constructed of real wood
*. Follow
up by drying with a soft cloth.
Use the cleaning and car-care
products available at your BMW
center.<
Care of upholstery materials Depressions in the upholstery that re-
sult from everyday use can be brushed
smooth by brushing against the nap
with a lightly dampened brush.
The tendency of the pile to lie in a par-
ticular direction on velour upholstery is
not a quality defect, and, just as on
home textiles or clothing, cannot be
avoided.
Lint on upholstery materials, textile or
leather remnants that have been worn
into the upholstery may be removed
with a lint brush or a Velcro brush. A
cleaning glove is available for especially
"stubborn" lint. Stains and fairly large
areas of dirt should be cleaned off with-
out delay, using lukewarm water and an
interior cleaner, stain remover or appro-
priate cleaning fluid. Brush the fabric
afterwards to restore its appearance.
If the vehicle is to be stored for an
extended period, or if it is exposed to
intense sunlight, cover all the seats or
the windows to prevent fading.
Use the cleaning and car-care
products available at your BMW
center.<

Cleaning and caring for your convertible topCareThe 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 vehicle has a light-
colored top.
Protect the vehicle from exposure to
intense sunlight whenever possible by
parking it in the shade. This will help 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 mildew stains from forming,
do not leave the top closed up in the
convertible top compartment for long
periods of time.
If the vehicle will be parked for lengthy
periods in an enclosed space, be sure
that the convertible top is dry and that
there is adequate ventilation.
Clean off bird droppings immediately,
since they attack the convertible top
and cause the rubber seals to swell due
to their caustic characteristics.Besides water, treat rubber seals only
with talcum powder, rubber care prod-
ucts or silicone spray, particularly when
they feel dry or tend to stick.
Eliminate noises, e.g. squeaks, using a
spray lubricant.
Depressions and discoloration may oc-
cur in the convertible top as a result of
improper maintenance and cleaning or
as the result of stresses from excessive
use. The convertible top and its seams
may also develop leaks. These occur-
rences are not covered by the warranty.
For repairs, please consult your BMW
center.
Washing your vehicleYou can take your BMW convertible
through automatic car washes. Brush-
less car washes are preferred.
If a brushless car wash is unavailable
and a brush car wash must be used,
modern systems with soft brushes are
preferable. Do not opt for special wax-
ing programs. The small amount of
beading wax always used in automatic
car washes will not harm your vehicle's
finish.
Whenever the vehicle is very dirty,
which is especially visible on light-col-
ored convertible tops, use the BMW
Convertible Cleaning Set to clean it.
Please proceed as follows:
Spray the convertible 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 convertible top should be
treated with a special impregnating
spray. Please follow the instructions on
the spray can.

Airbags 1 Front airbags for driver and
passenger
2 Side airbags (front)Important safety notices
Do not attempt to remove the gas
generators for the airbag restraint
system from the vehicle. Testing and
servicing must be performed by trained
technicians only. In the event of a mal-
function, deactivation or triggered actu-
ation (as a response to an accident) of
the airbag restraint system, consult
your BMW center for repairs or service
operations.
46cus032
Do not modify or tamper with either the
wiring or the individual components in
the airbag system. This includes the up-
holstered covers on the steering wheel,
in the instrument panel and in the side
trim panels of the doors. Do not apply
adhesive materials to these compo-
nents or cover or modify them in any
way. Do not attempt to remove or dis-
mantle the steering wheel.
To ensure compliance with official
safety regulations, have a BMW center
dispose of airbag generators.
Unprofessional attempts to service
the system could lead to failure in an
emergency or undesired airbag acti-
vation, either of which could result in
personal injury.<

Vehicle storage
If you intend to store the vehicle
for more than three months, have
the maintenance operations described
on this page performed.<
Preparations for storageHave your BMW center perform the fol-
lowing procedures:
1 Clean and apply a rustproofing agent
or other treatment to the engine,
engine compartment, undercarriage,
axles and major components in ac-
cordance with approved repair pro-
cedures. Washing the vehicle, any in-
terior cleaning and subsequent paint-
and chrome care, and cleaning any
rubber seals for the hood and doors,
should be carried out in compliance
with approved procedures as well
2 Change engine oil and oil filter at op-
erating temperature. As an additional
corrosion protection measure, an an-
ticorrosive agent can be added to the
engine when refueling in accordance
with the manufacturer's instructions
3 Check the coolant level and concen-
tration and top off if necessary
4 Fill the fuel tank completely to pre-
vent the formation of condensation
5 Increase the tire inflation pressure to
51 psi (350 kPa).
Before parking the vehicle1 Dry the parking brake and footbrakes
completely to keep the brake discs
and drums from corroding
2 Park the vehicle in a covered, dry,
and well-ventilated space. Place the
transmission in first gear or set the
selector lever to the "P" position.
Chock the wheels to prevent the ve-
hicle from rolling if necessary. Do not
apply the parking brake
3 Remove the battery, charge it com-
pletely and store it in a cool (but
frost-free) room
4 Remove the hardtop
* and store it
separately. Refer to page 121
5 Close the convertible top.
During storageRecharge the battery every six months.
If it is not recharged, it will not be ser-
viceable. Every time the battery drains,
especially over extended periods, its
service life is reduced.
Removing the vehicle from
storageRecharge the battery if the "Magic
Eye"
* turns black. Refer to page 162.
Then have Inspection I performed by
your BMW center, including a brake
fluid replacement if necessary. Refer to
the Service and Warranty Information
Booklet (US models) or the Warranty
and Service Guide (Canadian models).

OBD interface socket The interface socket for the onboard
diagnostics is located on the driver's
side at the left-hand bottom of the
dashboard and under a cover. The
cover has the letters "OBD" on it.
The purpose of the OBD system is to
ensure proper emission control system
operation for the life of the vehicle by
monitoring emission-related compo-
nents and systems for deterioration and
malfunction.460us250
An illuminated indicator informs
you of the need for service, not
that you need to stop the vehicle.
Your system should be checked by your
BMW center at the earliest possible
opportunity.
If the indicator blinks or flashes, this
indicates a high level of engine misfire.
Reduce speed and contact your near-
est BMW center immediately. Severe
engine misfire over only a short period
of time can seriously damage emission
control components, especially the
catalytic converter.
Warning lamp: "Service Engine
Soon" for Canadian models
When the fuel filler cap is not pro-
perly tightened, the OBD system
can detect the vapor leak and the indi-
cator will light up. If the fuel filler cap is
then tightened, the indicator will usually
go out after a short period of time.<

BatteryRemoval and installation
Do not disconnect the battery when
the engine is running. If you do so,
the ensuing voltage surge will damage
the vehicle's onboard electronics.
Do not make any modifications in the
wires to the positive terminal. If you do
so, the protective function of the safety
battery terminal is no longer ensured.
Repair and disposal must be performed
by trained technicians only.<
When removing the battery, disconnect
the cable on the negative terminal first,
then the cable on the positive terminal.
Loosen the center adjusting screw on
the battery retaining strap (use the
screwdriver included with the onboard
tool kit) and disconnect the strap.
When installing a battery, connect the
positive terminal first, then connect the
negative terminal.
When installing a battery, be sure
that it is mounted properly and that
the retaining bracket is installed with the
center adjustment screw, otherwise, the
battery will not be adequately secured
in case of an accident.<
Charging the battery Charge the battery in the vehicle only
when the engine is not running.
Before performing any work on
the electrical system, be sure to
unclamp the cable from the battery's
negative terminal. Failure to do so can
result in short-circuits, a fire or per-
sonal injury.<
If you plan to park the vehicle for longer
than 4 weeks, disconnect the battery
from the vehicle's electrical system by
disconnecting the cable at the negative
terminal. Then recharge the battery with
an appropriate battery charger.
If you intend to store the vehicle for
longer than 12 weeks, remove the bat-
tery, charge it and store it in a cool and
dust-free room where there is no dan-
ger of freezing. During storage, have
the battery recharged every 3 months.
Also, recharge the battery before it is
reinstalled. If this is not done, the bat-
tery will not be serviceable. Every time
the battery is drained, especially over
extended periods, its service life is
reduced.
Return used batteries to a recy-
cling point or your BMW center.
Maintain the battery in an upright posi-
tion for transport and storage. Secure
the battery to prevent it from tilting
during transport.<
Storage periods during which
the battery is disconnected are
not taken into consideration by the
Service Interval Display for changing
the brake fluid.
For this reason, be sure that the brake
fluid is changed every two years, re-
gardless of the information displayed.
Read and comply with the information
on page 136 covering this subject.<

Fuses Fuel filler doorIf an electrical accessory should fail,
switch it off and check the fuse. In the glove compartment1 Open the glove compartment and
turn the two white quick-release
fasteners outward. Spare fuses and
plastic tweezers are located on the
fuse holder
2 Use the plastic tweezers to remove
the fuse for the accessory or equip-
ment that has stopped working
3 Replace a burned-out fuse, recogniz-
able from the melted metal strip, with
a new fuse of the same color code or
ampere rating.460de062
A list of fuses, their respective ampere
ratings and the equipment in their cir-
cuits are all indicated below the fuse
holder.
To close the fuse holder, snap it into
position at the top and turn the two
fasteners inward.
Do not attempt to repair a burned-
out fuse or replace it with a fuse
with a different color or ampere rating.
Doing this could cause a fire in the ve-
hicle resulting from a circuit overload.<
If a fuse blows repeatedly, refer the
problem to your BMW center for repair.
Manual release Pull the knob with the fuel pump symbol
(arrow) on the right trim panel of the
luggage compartment. 46cde041

Deceleration sensors continuously
monitor the acceleration forces acting
upon the vehicle. If, as the result of a
frontal collision, a deceleration is
reached at which the protection of the
safety belts alone is no longer ade-
quate, the gas generators of the driver
and passenger-front airbags are ignited.
However, the passenger-side airbag is
only triggered if an additional sensor
has recognized that the passenger seat
is occupied.
In the event of a side collision, the
side airbags in the front are triggered
if necessary. 390de012
The airbags located under the marked
covers inflate and unfold in a matter of
a few milliseconds. In this process, they
tear through the designed separation
points of the upholstered covers or
press them out.
Because the inflation process must be
virtually instantaneous, it is necessarily
accompanied by a certain amount of
ignition and inflation noise. The gas
required to inflate the airbags is not
dangerous, and the smoke associated
with it dissipates.
The entire process is completed within
fractions of a second.Highly sensitive sensors monitor the
wheel speeds, steering angle, lateral
acceleration, brake pressure and the
movement of the vehicle around its
vertical axis.
If differences in the wheel speeds occur,
the system counteracts the danger of
wheelspin by reducing torque. If neces-
sary, the system also responds with
additional brake applications at the
rear wheels.
In addition, DSC permanently monitors
the vehicle's current operating condition
and compares it with an ideal condition
that is calculated from the sensor sig-
nals. If deviations from this occur (un-
dersteering or oversteering, for in-
stance), DSC can stabilize the vehicle in
fractions of a second by reducing engine
output and with the assistance of brak-
ing intervention at individual wheels.
As a result, most skids can be preven-
ted from their very onset.
You may need some time to become
accustomed to this system intervention.
However, it provides optimum drive
force and vehicle stability.
The braking intervention may be
accompanied by sounds specific to
the system.
