Roadster: fully automatic
convertible top*
The fully automatic convertible top combines
assured protection against the elements with
simple and easy handling.
Here are a few tips so that you get the most out
of your BMW:
>It is advisable to close the convertible top
when the vehicle is parked. When closed,
the top not only guards the passenger com-
partment from unforeseeable damage from
the weather, but also affords a degree of
protection against theft. Valuables, how-
ever, should only be kept in the locked
cargo bay, even when the convertible top is
closed.
>Never mount a roof-mounted luggage rack
system on the convertible top.
Do not operate the convertible top at tem-
peratures below 147/–106, otherwise
damage could result.
Never keep a wet convertible top in the convert-
ible top compartment for longer than one day,
otherwise the moisture could cause damage.
Do not lay objects on the convertible top, other-
wise they could fall off when the convertible top
is operated and cause damage or injuries.
Driving while the convertible top is not com-
pletely open or closed can cause vehicle dam-
age or personal injury.
Do not reach into the convertible top mecha-
nism during opening and closing. Keep children
away from the convertible top's range of move-
ment.
For safety reasons, whenever possible operate
the convertible top when the vehicle is station-
ary.<
If a convertible top operation has not yet
been completed as you start to drive off,
at a traffic light for example, you can continue
the procedure at moderate speed:
To do so, press and hold the corresponding button again.
At higher speeds, a vacuum effect in the pas-
senger compartment can cause the convertible
top to begin fluttering. Use the air conditioning
or automatic climate control to increase the air
flow rate and thus prevent a partial vacuum in
the vehicle.<
Before opening and closing
>Read and comply with the preceding safety
precautions.
>Make sure that the convertible top com-
partment panel in the cargo bay has been
folded down; refer to page23. Otherwise
the convertible top cannot be opened.
>Ensure that the luggage compartment lid/
tailgate is closed.
Opening and closing
With the key in ignition position 1 or higher,
refer to page40, and while the vehicle is sta-
tionary:
If at all possible, operate the convertible
top only with the engine running. This
saves unnecessary battery wear.
Before closing the convertible top, remove any
objects from the windshield frame that other-
wise could prevent the convertible top from
closing properly.<

The side windows will move down slightly
when you press the button for operating
the convertible top.
After the opening or closing operation, the win-
dows will move back up if you press the button

Opening and closing
28 for more than 2 seconds after the LED has gone
out.<
When the convertible top has been stored
in the convertible top compartment for an
extended period of time, e.g. in the winter
months because the hardtop was being used,
you may have to support the convertible top by
hand when closing it for the first time. If the con-
vertible top stops right before the closing phase
is completed, press against the front part of the
convertible top frame from the outside to help
the closing process along. Keep pressing the
button while doing so until the top starts mov-
ing on its own again.<
Indicator lamps
>The red LED in the button is lit while the
convertible top is in motion. It goes out as
soon as the opening or closing operation
has been completed.
>If the red LED in the button flashes after the
button has been released, then the opening
or closing operation has not yet been com-
pleted.
The movement can be continued in the
desired direction by pressing this button.
>If the yellow LED in the button comes on
when the button is pressed, the convertible
top compartment panel in the cargo bay has
been folded up. The convertible top cannot
be moved.
Interruption
The automatic sequence will be interrupted
immediately if you release the button that oper-
ates the top. The sequence can be continued in
the desired direction by pressing this button.
Do not close the side windows using the
power window buttons before the closing
procedure has been completed. Otherwise the
side windows may not close properly against
the rubber seal of the convertible top.<

safety belt. As supplemental restraint devices,
the airbags are designed to enhance the effec-
tiveness of the safety belts, and not to replace
them.
To fasten
Make sure you hear the lock engage in the belt

The 'Fasten safety belts' reminder is issued as
long as the driver's safety belt has not been fas-
tened. The 'Fasten safety belts' reminder is also
activated at road speeds above approx. 5 mph/
8 km/h if the passenger's safety belt is not fas-
tened, if heavy objects are placed on the pas-
senger seat, or if driver or passenger unfasten
their safety belts.

Adjustments

Damaged safety belts
When the belt system has absorbed an
accident or has been damaged, have the
system and its belt tensioners replaced and the
b e l t a n c h o r s c h e c k e d . H a v e t h i s w o r k d o n e o n l y
by your BMW center or at a workshop that
works according to BMW repair procedures
with correspondingly trained personnel. Other-
wise, it is not guaranteed that the safety devices
will function properly.<
Mirrors
Exterior mirrors
The passenger's mirror is more convex
than the driver's mirror. The objects seen
in the mirror are closer than they appear. Do not
gauge your distance from traffic behind you on
the basis of what you see in the mirror; other-
wise there is an increased risk of an accident.<

The mirrors can also be adjusted manually:
press on the edges of the lens.
Folding mirrors in or out*
The mirrors can be folded in or out up to a road
speed of approx. 6 mph/10 km/h by pressing
button3. This can be useful on narrow roads,
for example, or to reset the mirrors to their cor-
rect positions after they were folded in.
Automatic heating*
Both exterior mirrors are automatically heated
when the engine is running or the ignition is
switched on.
Interior rearview mirror
Turn the knob to reduce glare from the head-
lamps of cars behind you when driving at night.
Interior and exterior mirrors with
automatic dimming feature*
The automatic dimming feature of the interior
and exterior mirrors
* is controlled by two photo
cells in the interior rearview mirror. In the Road-
ster, one is located in the top of the mirror
frame, see arrow. In the Coupe, it is located at
the bottom of the mirror frame. The other photo
cell is on the back of the mirror.
In order to ensure that the system functions
correctly, keep the photocells clean, do not
cover the area between the interior rearview
mirror and windshield, and do not affix adhesive
labels or stickers of any kind to the windshield
directly in front of the mirror.

Special starting conditions
In the following situations, press the accelerator
pedal halfway down when starting the engine:
>If the engine does not start on the first
attempt, for instance when it is extremely
hot or cold.
>If the engine is started at very low tempera-
tures, below approx. +57/–156, at high
altitudes above approx. 3,300 ft/1,000 m.
Avoid frequent starting attempts in quick
succession or repeated starting attempts
during which the engine does not start. Other-
wise, the fuel is not burned or inadequately
burned; there is a danger of overheating and
damaging the catalytic converter.<
Switching off the engine
Do not remove the key while the vehicle is
still moving. Otherwise, the steering lock
would engage when the steering wheel is
turned.
