Caring for your vehicleThe buildup of an electrostatic charge
on the seat covers, particularly if atmo-
spheric humidity is low, can give the
occupants an unpleasant electric shock
if they touch metal body parts after leav-
ing the vehicle. Although this not dan-
gerous in any way, it can be avoided by
touching a bare or polished metal part
of the vehicle while getting out.Leather care The leather upholstery
* used by BMW
is a natural product of the highest qual-
ity, processed using state-of-the-art
methods to ensure that it will maintain
its high quality for years to come, pro-
vided that it is properly cared for.
Because this product is manufactured
using natural materials, you must make
allowance for its special characteristics
and for the peculiarities of its use
and care.
Regular periodic cleaning and care are
essential, as dust and road dirt act as
abrasives in the pores and creases of
the material. This leads to wear spots
and premature brittleness on the sur-
face of the leather. We therefore sug-
gest that you clean the leather with a
vacuum cleaner or cloth at frequent
intervals.For cleaning, use BMW leather
cleaning foam.
Since dirt and grease gradually attack
the protective layer of the leather, the
cleaned surfaces should be treated
with BMW leather care agent. This also
acts as an antistatic agent.
For protection against dampness or
moisture, treat the leather with an im-
pregnating agent made by BMW.
We recommend that you perform this
procedure twice a year on leather
exposed to normal use.
Spills should be wiped up immediately.
Remove grease and oil stains by dab-
bing with spot remover. Avoid rubbing.
If the upholstery is to be exposed to in-
tense sunlight or if the vehicle is to be
stored for an extended period, cover all
leather surfaces (or, better yet, the win-
dows) to prevent fading.
Use the cleaning and car-care
products available at your BMW
center.<
Cleaning agents can contain sub-
stances that are dangerous or
pose health risks. For this reason,
always comply with the warnings and
danger labels on the packaging.
When cleaning the vehicle's interior,
open the doors or windows (if the con-
vertible top has been closed). Never
clean your vehicle with solvents or
other materials not specifically in-
tended for this purpose.<

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.

Cleaning and caring for your convertible topDo not use spot removers, paint thin-
ners, solvents, gasoline or similar sub-
stances for removing spots from the
convertible top or from the rear win-
dow. These materials destroy the rub-
ber layer, which will lead to leaks. Use
only BMW-approved cleaners.
Cleaning agents can contain sub-
stances that are dangerous or
that pose health risks. For this reason,
always comply with the warnings and
danger notices on the packaging.
Open the doors or windows on your
vehicle when cleaning the interior.
Never clean your vehicle with solvents
not specifically intended for it.c
Getting your vehicle ready for
cleaningIn order to maintain free access to your
convertible top compartment, rest the
rear convertible top bar against the
convertible top compartment lid (refer
to illustration).
Release the lid locks for the con-
vertible top first; refer to page 45
or 50.<46cde072

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.<

The lamps and bulbs are essential fac-
tors contributing to the safety of your
vehicle. For this reason, follow the in-
structions below carefully when replac-
ing a bulb. If you are not familiar with
any of the procedures, consult your
BMW center.
Do not touch the glass portion of
a new bulb with your bare hands
since even small amounts of impurities
burn into the surface and reduce the
service life of the bulb. Use a clean
cloth, paper napkin, or a similar mate-
rial, or hold the bulb by its metallic
base.<
A replacement bulb set is available from
your BMW center.
Whenever working on the electri-
cal system, switch off the electri-
cal accessory you are working on or
disconnect the cable from the negative
terminal of the battery. Failure to do this
could result in short circuits.
To prevent injuries and damage, com-
ply with any instructions provided by
the bulb manufacturer.<

Changing a wheel
Safety measures in the event of a
flat tire or wheel change:
Stop the vehicle as far as possible from
passing traffic. Park on a firm, flat sur-
face. Switch on the hazard flashers.
Turn the steering wheel to the straight-
ahead position, remove the key and en-
gage the steering lock. Shift into 1st or
reverse (selector lever in "Park" with au-
tomatic transmission) and engage the
parking brake.
Have all passengers leave the vehicle
and remain well away from your immedi-
ate working area (behind a guardrail, for
instance).
If a warning triangle
* or portable hazard
warning lamp is available, set it up on
the roadside at an appropriate distance
from the rear of the vehicle. Comply with
all safety guidelines and regulations.
Change the wheel only on a level, firm
surface that is not slippery. Avoid jack-
ing the vehicle on a soft or slippery sup-
port surface (snow, ice, loose gravel,
etc.), as it could slide sideways.
Position the jack on a firm support sur-
face.
Do not place wooden blocks or similar
objects under the jack, otherwise, the
jack might not be able to reach its full
support capacity because of the limited
height.
Do not lie under the vehicle or start the
engine when the vehicle is supported by
the jack. Failure to comply with this cre-
ates a risk of fatal injury.<
Your BMW has a space-saver spare
tire for temporary use to ensure your
mobility.
To remove the space-saver spare
tire, lift the floor panel in the lug-
gage compartment completely out
(refer to page 41).<
What you will needIn order to avoid rattling noises later,
note the position of the tools when you
remove them and return them to their
original position when you are through
using them.
>Jack (1)
Raise the floor panel in the luggage
compartment (refer to page 41) and
unscrew the red wing nut (arrow).
When you have completed your work,
screw the jack all the way back down.
Fold the handle back and insert it into
its holder
>Wedge (2)
The wedge, or wheel chock, is lo-
cated behind the jack on the luggage
compartment's rear wall. Loosen the
wing nut to remove it46cde038

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.
