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 +14°F/-10°C, do
not move the convertible top or damage
may occur.
Do not keep the convertible top in the 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, or
they may fall off when the top is operated 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 convertible top while it is moving.
For safety reasons, only move the convertible
top while the vehicle is standing, 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
page108, 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 page36.
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.<

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.

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.

Maintenance

Maintenance
BMW Maintenance System
The BMW Maintenance System supports the
preservation of the traffic and operating safety
of your BMW. The objective is to optimize
efforts with respect to minimal vehicle mainte-
nance costs.
If and when you come to sell your BMW, a com-
prehensive record of servicing will prove a sig-
nificant benefit.
Condition Based Service CBS
Sensors and special algorithms take the differ-
ent driving conditions of your BMW into
account. Condition Based Service uses this to
determine the current and future service
requirements. By letting you define a service
and maintenance regimen that reflects your
own individual requirements, the system builds
the basis for trouble-free driving.
On the Control Display, you can have the
remaining times or distances for selected main-
tenance tasks and any legally prescribed dates
displayed, refer to page71:
>Engine oil
>Brake pads: separately for front and rear
>Brake fluid
>Vehicle check
>Legally mandated inspections depending
on local regulations
Service data in the remote control
Your vehicle continuously stores service-
requirement information in the remote control
while you are driving. Your BMW Service Advi-
sor can read out this data from the remote con-
trol unit, and propose an optimized mainte-
nance approach. Whenever you take your car in
for servicing you should therefore hand your
BMW Service Advisor the remote control unit
that you last used.
Make sure that the date is always set cor-
rectly, refer to page75; otherwise the
effectiveness of Condition Based Service CBS
is not assured.<
