Convertible: top
The fully automatic top combines reliable
weather protection with simple and easy-to-
use operation.
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 area.
>Do not attach roof-mounted luggage sys-
tems to the convertible top.
>If the top is opened while it is wet, e.g. after
driving in the rain, water may drip into the
cargo area. If necessary, remove items from
the cargo area beforehand to avoid water
stains or soiling.
At temperatures below +147/–106, do
not move the convertible top as this could
result in damage.
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.<
Before opening and closing
>Comply with the safety precautions
described above.
>Ensure that the cargo area partition is
folded down and engaged on both sides,
refer to page102; otherwise, it will not be
possible to open the convertible top.
>Ensure that the cargo does not press
against the cargo area partition from below.
>Ensure that the trunk lid is closed.
Opening and closing

When properly used, these tires meet the high-
est standards in terms of safety and handling
characteristics.
Special characteristics of winter tires
BMW recommends winter tires for winter roads
or at temperatures below +457/+76.
Although all-season M+S tires provide better
winter traction than summer tires, they gener-
ally fail to provide the same levels of cold-
weather performance as winter tires.
Pay attention to speed
Always comply with the speed limit for the
winter tires mounted on your car; failure
to do so could result in tire damage and acci-
dents.<
If the car is capable of speeds higher than that
permitted for the winter tires, a label stating the
maximum permitted speed for the mounted
tires must be displayed in your field of view.
Specialist tire dealers and your BMW center
can supply these labels.
Storage
Store wheels and tires in a cool, dry place with
as little exposure to light as possible. Always
protect tires against all contact with oil, grease
and fuels.
Do not exceed the maximum tire inflation pres-
sure indicated on the sidewall of the tire.
Swapping wheels between axles
BMW advises against swapping wheels
between the front and rear axles, even if all tires
have the same size, as this could impair driving
characteristics. If the tires are of mixed sizes,
swapping wheels between the axles is not per-
missible.
Snow chains*
Only certain fine-link snow chains have been
tested by BMW, classified as safe for use and
recommended. Consult your BMW center for
more information. Snow chains must be mounted in pairs and on the rear wheels only.
Observe the manufacturer's instructions when
mounting snow chains. Do not exceed a speed
of 30 mph/50 km/h with chains.
Do not initialize the Flat Tire Monitor if
snow chains are mounted; otherwise, the
instrument might issue an incorrect reading.
When driving with snow chains, you may find it
helpful to activate DTC temporarily, refer to
page76.<

Engine oil
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 precise measurement and display of the oil
level, the engine must be at operating tempera-
ture, i.e. following at least 6.2 miles/10 km of
uninterrupted driving. 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.
Display in the instrument cluster
1.Push button 1 in the turn indicator lever up
or down repeatedly until the appropriate
symbol is shown in the display, accompa-
nied by the word "OIL".
2.Press button 2.
The oil level is checked and the reading dis-
played.

Add engine oil as soon as possible, but no
more than 1 US quart/1 liter, refer also to
Adding engine oil on page201.
4Oil level is too high.
Too much oil will harm the engine.
Have the vehicle checked without
delay.<
5The oil level sensor is defective.

tance remaining to the next oil service, refer
to page203. Have the system checked as
soon as possible.

Have the vehicle checked immedi-
ately; otherwise, the excess oil may
lead to engine damage.<
>"Measurement inactive. Have this
checked.":
Do not add engine oil. Before continuing to
drive, note the recalculated remaining mile-
age until the next oil change service, refer to
Service requirements on page67. 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 Control Display. Add oil within the next
125 miles/200 km; otherwise, the engine could
be damaged.<
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 routinely approves specific
oils after testing them extensively.
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 0W-40,
0W-30, 5W-40 and 5W-30 SAE
classes.<
These oils can be used for driving at all outside
temperatures.
Coolant
Do not add coolant to the cooling system
when the engine is hot. Escaping coolant
can cause burns.<
Coolant consists of half water and half additive.
Not all commercially available additives are suit-
able for your BMW. Ask your BMW center for
suitable additives.
Only use suitable additives; otherwise,
engine damage may result. Because
additives are harmful to your health, it is impor-
tant to follow the instructions on the contain-
ers.<
Comply with the appropriate environ-
mental protection regulations when dis-
posing of coolant additives.<
