The following tips will enhance your driving
pleasure in your convertible:
>It is advisable that you close the convertible
top when you park the vehicle. Not only
does the closed top protect the vehicle inte-
rior against unanticipated weather damage,
it also offers a certain amount of theft pro-
tection. However, even when the top is
closed, valuables should only be stored in
the locked cargo bay.
>Do not attach roof-mounted luggage sys-
tems to the convertible top.
>When opening a wet top, e.g. after driving in
the rain, water may drip into the cargo bay. If
necessary, remove items from the cargo
bay beforehand to avoid water stains or soil-
ing.
At temperatures below +147/–106, do
not move the convertible top or damage
may occur.
Do not keep the convertible top in the convert-
ible top box for longer than one day if it is wet,
otherwise the moisture may cause damage.
Do not place objects on the convertible top, as
otherwise they may fall off when you operate
the convertible top and cause damage or injury.
Never move the convertible top when the roll-
over protection system is in the activated posi-
tion.
Always fully complete a convertible top move-
ment. Driving with the convertible top incom-
pletely opened or closed can result in damage
or injury.
Do not reach into the mechanism during the
opening or closing procedure. Keep children
away from the opening/closing path of the con-
vertible top.
For safety reasons, only move the convertible
top when the vehicle is stationary, if possible.<
The convertible top swings upward when
opening and closing. When operating the
convertible top in a garage, under a bridge, etc.,
ensure that there are at least 6 ft 7 in/2 m of
headroom, otherwise the vehicle may be dam-
aged. >Comply with the safety precautions
described above.
>Ensure that the cargo bay partition is folded
down and engaged on both sides, refer to
page109, otherwise it will not be possible
to open the convertible top.
>Ensure that the cargo does not press
against the cargo bay partition from below.
>Ensure that the luggage compartment lid is
closed.
Opening and closing
Convertible top operation with convenient
access, refer also to page30.
As of radio readiness, refer to page58:
If possible, conserve the battery by only
operating the convertible top when the
engine is running.
Before closing the convertible top, remove all
foreign objects from the windshield frame as
these could prevent the hardtop from closing
properly.<

The engine oil consumption is dependent on
driving style and driving conditions.
Checking oil level
Your car is equipped with an electronic oil-level
monitor.
For a precise measurement and display of the
oil level, it is necessary that the engine be at
operating temperature, i.e. after uninterrupted
driving for at least approx. 6.5 miles/10 km. You
can have the oil level displayed while you are
driving, or while the vehicle is at a standstill on a
level surface and the engine is running.

your journey. Note the newly calculated dis-
tance remaining to the next oil service, refer
to page217. Have the system checked as
soon as possible.
Adding engine oil
Do not add 1 US quart/1 liter of engine oil until a
corresponding message is shown on the Con-
trol Display.
Add oil within the next 125 miles/200 km,
otherwise the engine could be dam-
aged.<
Keep oils, greases, etc. out of the reach of
children and comply with the relevant
warnings on the containers. Otherwise, health
hazards may result.<
Oil change
Have oil changed only at your BMW center or at
a workshop that works according to BMW
repair procedures with correspondingly trained
personnel.
Specified engine oils
The quality of the engine oil selected has critical
significance for the operation and service life of
an engine. BMW continuously approves spe-
cific oils after confirming their suitability for use
in its vehicles with extensive testing.
Do not use oil additives as these may
cause engine damage.<
Only use approved BMW High Performance
Synthetic Oil.
If BMW High Performance Synthetic Oil is not
available, you can add small quantities of other
synthetic oils in between oil changes. Only use
oils with the API SM specification or higher.
Your BMW center will be glad to answer
any questions regarding BMW High Per-
formance Synthetic Oil or approved synthetic
oils.<
You can also call BMW of North America at
1-800-831-1117 or visit the website
www.bmwusa.com to obtain this information.
Viscosity ratings
Viscosity is a measure of an oil's flow rating and
is categorized in SAE classes.
Selecting the appropriate SAE class depends
on the regional climatic conditions in which you
normally drive your BMW.
Approved oils belong to the 5W-40 and
5W-30 classes.<
These oils can be used for driving at all outside
temperatures.

Care
Care products
Regular cleaning and care contributes signifi-
cantly to the value retention of your BMW.
BMW recommends cleaning and caring for your
vehicle with products that are approved by
BMW for this purpose.
Your BMW center will be happy to advise you on
the products and services available for cleaning
and caring for your BMW.
Original BMW CareProducts have been
material tested, laboratory checked and
proven in the field, and offer optimal care and
protection for your vehicle.<
Do not use cleaners that contain alcohol
or solvents as these may result in dam-
age.<
Cleaning agents can contain substances
that are dangerous or hazardous to your
health. Therefore, follow the warning and safety
instructions on the packaging. When cleaning
inside the vehicle, always open the doors or
windows of the vehicle. In enclosed areas, pro-
vide for sufficient ventilation. Only use products
designed for cleaning vehicles.<
Exterior care
Washing the vehicle
Especially during the winter months,
ensure that the vehicle is washed more
frequently. Heavy soiling and road salt can lead
to vehicle damage.<
After washing the vehicle, apply the
brakes briefly to dry them, otherwise
water can reduce braking efficiency over the
short term and brake discs can corrode.<
Automatic car washes
Preference should be given to cloth car washes.Do not use high-pressure car washes,
otherwise water may drip into the vehicle
around the windows.<
Before driving into a car wash, ensure that it is
suitable for your BMW. Check the following:
>Dimensions of your vehicle, refer to
page237.
>If necessary: fold in the exterior mirrors,
refer to page52
>Maximum permissible tire width
>In convertibles, do not treat the convertible
top with wax. Ensure that a program is avail-
able that does not apply wax or is designed
specifically for convertibles.
Preparations before driving into an automatic
car wash:
>Unscrew rod antenna
*
>Deactivate the rain sensor* to avoid unin-
tentional activation of the wipers.
>Remove additional attachments, e.g.
spoiler or telephone antennas, if there is a
possibility that they could be damaged.
Automatic transmission
Before driving into an automatic car wash, per-
form the following steps to ensure that the vehi-
cle can roll:
1.Insert the remote control, even with conve-
nient access, into the ignition lock.
2.Engage transmission position N.
3.Release the parking brake.
4.Switch off the engine.
5.Leave the remote control in the ignition lock
so that the vehicle can roll.
Steam jets / high-pressure washers
When using steam jets or high-pressure
washers, ensure that you maintain suffi-
cient clearance to the vehicle and do not exceed
a temperature of 1407/606.
Insufficient clearance or excessive pressure or

Care
220 temperature can lead to component damage or
water penetration. Follow the operating instruc-
tions of the high-pressure washer.<
When using high-pressure washers, do
not spray against the sensors and cam-
eras, e.g. of the Park Distance Control or Rear
View Camera, for an extended period and main-
tain a distance of at least 12 in/30 cm.<
Manual car wash
When washing the vehicle by hand, use large
quantities of water and car shampoo if neces-
sary. Clean the vehicle with a sponge or wash-
ing brush, applying light pressure only.
Before cleaning the windshield, deacti-
vate the rain sensor or switch off the igni-
tion to prevent unintentional activation of the
wipers.<
Observe local regulations pertaining to
washing vehicles by hand.<
Headlamps
Do not rub them dry and do not use abrasive or
corrosive cleaning agents.
Remove contamination, such as insects, by
soaking with shampoo or insect remover and
then rinsing with plenty of water.
Thaw ice with a windshield de-icer and do not
use an ice scraper.
Windows
Clean the inside and outside surfaces of the
windows and the mirrors with window cleaner.
Do not clean the mirrors with cleaners
containing quartz.<
Wiper blades
Clean with soapy water and replace regularly to
avoid streaking.
Wax and preservative residue and con-
tamination on the window can lead to
streaking when operating the windshield wip-
ers, leading to premature wear of the wiper
blades and causing the rain sensor to malfunc-
tion.<
Convertible top care
The appearance and life of the convertible top
depend on proper care and operation.
Follow these instructions:
>Do not fold the convertible top into the con-
vertible top box when the top is wet or fro-
zen, as this may cause water spots, mold
stains or chafed areas.
>If water spots occur on the inside headliner
despite precautions, remove them using a
microfiber cloth and interior cleaner.
>If the vehicle is parked in enclosed areas for
extended periods, ensure that there is suffi-
cient ventilation.
>Remove bird droppings immediately, as
their corrosive ingredients attack the con-
vertible top and damage the rubber seals.
To remove stains from the convertible
top, do not use stain removers, paint thin-
ners, solvents, benzine or similar substances.
These substances may damage the rubber
parts. Improper care and cleaning may cause
the convertible top and convertible top seams
to become leaky.<
To remove heavy soiling, use a special convert-
ible top cleaner.
Follow the manufacturer's instructions for use.
After washing the convertible top three to five
times, treat it with an impregnating agent.
Paintwork care
Regular care contributes to value retention and
protects the paintwork against the long-term
effects of damaging substances.
Region-specific environmental influences can
damage the vehicle paintwork. Therefore, it is
important to adapt the frequency and scope of
car care accordingly.
Immediately remove very aggressive sub-
stances, e.g. spilled fuel, oil, grease, tree resin
or bird droppings, to prevent damage to the
paintwork.
