The safety belts should be cleaned with
a mild soap and water solution without
being removed from the car. Never
attempt chemical or dry cleaning, as
damage to the belt fabric could result.
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.
Please use only a damp cloth to clean
wooden fascia panels and components.
Follow up by drying with a soft cloth.

Products for cleaning and care are
available from your BMW Retailer.c
Care of upholstery materialsDepressions resulting in the upholstered
materials in the course of everyday use
can be brushed up by brushing with a
lightly dampened brush "against the
nap".
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, can not be
avoided.
Fuzz on upholstery materials, rubbed-in
fabric or suede residues can be removed
with a fuzz or Velcro
â brush. A cleaning
glove is available for particularly "stub-
born" fuzz. Stains and fairly large areas
of dirt should be cleaned off without
delay, using lukewarm water and an
interior cleaner, stain remover or clean-
ing-grade benzene. Brush the fabric
afterwards to restore its appearance.
If the upholstery is to be exposed to
intense sunlight or if the vehicle is to be
stored for an extended period, cover all
seats to prevent fading.
b
A full range of car-care products is
available from your BMW Retailer.cThe build-up 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
leaving the vehicle. Although this is not
dangerous in any way, it can be
avoided by touching a bare or polished
metal part of the car while getting out.
If necessary, anti-static products can
be used to eliminate this effect to a
large extent.

Leather careThe 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
as well as 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 dust cloth at frequent
intervals.
For cleaning, use BMW leather cleaning
foam.
As dirt and grease can slowly attack the
protective layer of the leather, the
cleaned leather surfaces must be
treated with BMW Leather Care. This
serves also as an anti-static agent.
To protect against moisture and water
you can treat the leather with BMW
Impregnating Agent.We recommend that you perform this
procedure twice a year on leather ex-
posed to normal use.
Spills should be wiped up immediately.
Remove grease and oil stains without
rubbing, but rather by dabbing with
spot remover.
If the upholstery is to be exposed to
intense 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.
a
Cleaning agents can contain dan-
gerous or unhealthy ingredients. There-
fore always observe the warnings and
danger notices on the package.
Open the doors or windows on your ve-
hicle when cleaning the interior.
Never clean your vehicle with solvents
or other materials not specifically in-
tended for this application.c

Never use spot remover, paint thinner,
solvents, gasoline etc. to remove spots
from the convertible top and from the
rear window, as these substances
destroy the rubber seals and lead to
leaks. Use only BMW-approved clean-
ers.
In addition to the advantage of being
extremely flexible, the rear window also
has the disadvantage of having a rela-
tively soft surface. For this reason, only
clean the rear window with a soft, anti-
static cloth or with BMW Convertible
Rear Window Cleaner.
If you wash the vehicle frequently in
brush car washes, and in particular in
those with hard brushes, faint scratches
in the rear window may result. With the
window replacement system you can
replace a heavily scratched window at a
relatively low price. Please contact your
authorized BMW Retailer for additional
information. b

Cleaning agents can contain sub-
stances that are dangerous or bad for
your health. Therefore always observe
the warnings and danger notices on the
package.

hicle when cleaning the interior.
Never clean your vehicle with solvents
or other materials not specifically in-
tended for this application.c
Hardtop:Please follow the instructions for car
care from page 131.If the vehicle is to be temporarily stored
for more than three months, have the
following maintenance performed by
your BMW Retailer:
1 Cleaning, preservation and retreat-
ment of the engine, engine compart-
ment, underbody, axles and
subassemblies in accordance with
the factory speciÞcations. Vehicle

lowed by paint and chrome care.
Clean rubber seals of the hood, lug-
gage compartment lid and doors and
rub with either talcum powder or
glycerine oil.
2 Change engine oil and oil Þlter at
operating temperature. As an addi-
tional corrosion protection measure,
an anti-corrosive agent can be added
to the engine in accordance with the
manufacturer's instructions.
3 Check the coolant level and concen-
tration and top up if necessary.
4 Check the acid level in the battery
cells and add distilled water if neces-
sary.
5 Increase the tire inßation pressure to
50.9 psi (3.5 bar).
