ment.c
Fully automatic convertible top
operation
*
The fully automatic convertible top per-
fectly combines extremely simple, com-
fortable operation with reliable protec-
tion from the elements. Here are a few
tips to ensure that you have years of
pleasure with your convertible:
It is advisable to close the top when the
vehicle is parked. The closed top not
only protects the passenger compart-
ment from unforeseen weather-related
damage, it also provides a certain
degree of theft protection. Even with
the top closed, it is always advisable to
keep valuables locked in the luggage
compartment.
Do not mount roof racks on the convert-
ible top. Please contact your BMW
Retailer for suitable mounting equip-
ment and other accessories.
To prevent damage, do not operate the
top at temperatures below 325F (0
6
).
To protect the battery, it is advisable to
operate the top with the engine running
when possible.

The luggage compartment can not
be opened during convertible top oper-
ation.
The side windows move down slightly
when the convertible top operating but-
ton is pressed; if you continue to press
the button after the indicator lamp goes
out, they move up again as soon as the
opening process is completed.c
a
The side windows must be low-
ered slightly during convertible top op-
eration. If the convertible top operation
is interrupted, do not close the side win-
dows with the power window switches.
If the opening or closing process is in-
terrupted, it may not be possible to open
the luggage compartment.
To prevent damage from continuous
dampness, never fold down the convert-
ible top when wet.c
Convenience closing with the
driver's door lockHold the key in the "lock" position with
the door closed.
The windows/sunroof stop moving
immediately when you release the key.b
At higher speeds, low air pressure
in the passenger compartment can
cause the convertible top or the rear
window to begin to flutter. Increase the
air intake via the ventilation control to
prevent low pressure from resulting in
the passenger compartment.c
Closing convertible top manually
when electrical operation failsb
Manual closing is best carried out
from outside the vehicle with the driver's
door open and the driver's seat folded
forward. The rear seat bench must not
be occupied while doing so.c
1 Raise the left rear seat. Pull out the
strap until resistance is felt. Now con-
tinue to pull Þrmly (two audible clicks)
to disengage the drives for the con-
vertible top and convertible top com-
partment lid.

BMW ConvertibleVehicles without ski bag
*: Storage
compartment, accessible by removing
the filler piece and releasing the trim
(refer to page 97).
The rear backrest is divided in the cen-
ter. Each side can be folded down sep-
arately to carry long objects.
To release:
Reach into the handle recess, press
down and pull forward.
When folding back the rear backrest,
make sure that the locking device is
properly engaged to ensure proper
operation of the safety belt. The red
slide must move downward.
If the rear backrest is not locked, the
safety belt can not be pulled out.It makes possible a safe, convenient
transport of 3 to a maximum of 4 pairs
of skis (BMW Convertible, maximum of
2 pairs of skis).
The length of the ski bag in combination
with the additional space in the luggage
compartment makes it possible to trans-
port skis of up to 6.8 ft. (2.10 m) in
length. Because the ski bag contracts
as additional skis are inserted, the bag
is suitable for transporting only two
pairs of skis when both are a maximum
of 6.8 ft. (2.10 m) long.
If the ski bag is not used for longer peri-
ods, it should be stored in a dry place.
It is advisable to wipe off any water
which has collected on the waterproof
ski bag from time to time.

The ski bag must not hinder the
driver during driving.c

A special luggage system is available as
an option for your BMW. Please
observe the precautions included with
the installation instructions.
Because roof racks raise the center of
gravity of the car when loaded, they
exercise a major effect on its handling
and steering response.
You should therefore always remember
not to exceed the approved roof weight,
the approved gross vehicle weight or
the axle weights when loading the rack.
For specifications refer to "Technical
data", page 163ff.
Make sure that the load is not too heavy,
and attempt to distribute it evenly.
Always load the heaviest items first (on
the bottom).
Make sure there is sufficient space to
raise the sliding/tilt sunroof.Secure the roof luggage correctly and
securely to prevent it from shifting or
being lost during driving (danger to fol-
lowing traffic).
Drive smoothly: avoid sudden accelera-
tion and braking maneuvers; corner
gently.
The roof load increases the surface
area exposed to the wind: increased
fuel consumption and stress on the roof
are the immediate results.Roof-mounted luggage rack*

The BMW Maintenance System has
been designed as a reliable means of
providing the customer with maximum
vehicle safety and reliability with mini-
mum complication and expense.
Please remember that regular periodic
maintenance plays an essential part in
ensuring continued vehicle security. It
also helps maintain the resale value of
the vehicle.
Service Interval DisplayAdvanced technology is employed to
calculate the optimal maintenance
intervals, which are then indicated in
the Service Interval Display. While con-
ventional maintenance systems rely on
mileage alone to determine when ser-
vice is due, the BMW Maintenance Sys-
tem reflects the actual conditions under
which the vehicle is operated, because
mileage is not simply mileage:
From the point of view of maintenance,
62,000 miles (100,000 km) accumulated
in short-distance driving are not the
equivalent of the same distance cov-
ered in long-distance highway travel.
The BMW Maintenance System
includes the Engine Oil Service as well
as Inspections I and II.
Determining the maintenance intervals
according to the actual loads on the car
covers every kind of operating situation.
However, drivers who cover only
extremely short distances - substantially
less than 6,200 miles (10,000 km) annu-
ally - should have the engine oil changed
at least once a year, as it continues to
age whether or not the car is used on a
regular basis.
Service and Warranty Information
bookletPlease refer to the Service and War-
ranty Information booklet for additional
information on maintenance intervals
and procedures.
Depending on operating conditions, as
a precaution against rust it may be a
good idea to have the body checked for
stone damage and chips at the same
time.
Please ensure that all maintenance
operations are entered in the Service
and Warranty Information booklet upon
completion. These entries will consti-
tute your proof that the vehicle has
received regular maintenance. They
are also required for warranty claims.b
Have your BMW Retailer carry out
the maintenance and repair. Your BMW
Retailer is always informed on the latest
maintenance work and repair tech-
niques and equipped with the required
special tools. In addition, the testing of
parts known from experience to be sub-
ject to wear is a permanent part of the
maintenance specifications.c

Waxing your carProtect the finish using carnauba or
synthetic-based waxes only.
The best way to determine when the
finish needs to be waxed is by noting
when water stops beading on the sur-
face.
You can use a glass cleaner to remove
any wax or silicone that may have been
left on the windows during waxing.b
A full range of car-care products is
available from your BMW Retailer.c
Paint damageYou can touch up small areas of dam-
age with BMW spray paint, a BWM
touch-up stick or BMW paint tape.
The paint color code for your car is pro-
vided on a sticker located next to the
type plate and on the first page of your
Service and Warranty Information book-
let.
Damage caused by flying stones,
scratches, etc. must be touched up
without delay to prevent rust from form-
ing.
If corrosion has started to form in an
area with paint damage, remove all rust
and clean the area, then prime the area
with a BMW Primer Stick. Finally, apply
the finish coat. Wait a few days, then
polish the repaired area. Finish by
applying a wax preservative.
More extensive paint damage should be
professionally repaired in accordance
with the manufacturer's instructions.
Your BMW Retailer uses original BMW
finish materials in accordance with offi-
cial repair procedures.
Caring for other vehicle compo-
nents and materialsLight-alloy wheels
* should be treated
with alloy wheel cleaner, particularly dur-
ing the winter months. Refrain from using
aggressive products containing acids,
strong alkalis or abrasives. Alloy wheels
should not be cleaned with a steam jet
operating at temperatures in excess of
140 5F (606) (note manufacturer's
instructions).
You can use window and glass cleaner to
clean inside window surfaces and mir-
rors without smearing and streaking.
Never use polishing pastes or abrasive
(quartz) cleansers on mirror lenses.
Clean plastic parts, imitation leather sur-
faces, the roof lining, the lenses of lamps,
the glass cover of the instrument panel
and all dull black sprayed parts with
water or products for the care of plastics.
Avoid soaking the headliner. Never use
solvents such as lacquer thinner, heavy-
duty grease remover, fuels, etc.
Rubber components should be cleaned
with water only; a rubber treatment or sil-
icone spray may also be applied.
Clean the wiper blades with soapy water.
The wiper blades should be replaced
twice a year, before and after the cold
season.
