Manual convertible top
The fabric top offers perfect protection
against the weather and it can be opened
easily and quickly by one person alone.
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.
The closed convertible top not only pro-
tects the passenger compartment from
unforeseeable damage from the
weather, but also provides a certain
degree of theft protection
>In addition, only keep valuables in the
locked luggage compartment, even
with the convertible top closed
>When the convertible top is open, the
central locking system also locks the
release button for the convertible top.
The convertible top cannot be oper-
ated. This provides better theft protec-
tion for valuables stored in the luggage
compartment
>Never mount a roof-mounted luggage
rack system on the convertible top.
To open the convertible top
Operate the convertible top only
when the vehicle is stationary.
Never store the convertible top for longer
than one day while it is wet to avoid perma-
nent damage from moisture.<
Before opening the convertible top,
make sure that the convertible top
compartment panel in the luggage com-
partment is lowered to avoid any possible
damage; refer to page 20.<1.Flip the handle out and turn it to the end
stop
2.Open the convertible top and push it
toward the rear of the vehicle
3.Gently swing the convertible top down-
ward and press until it engages audibly.

Opening and closing

To close the convertible top
1.Press button 1
The convertible top is released and
moves up slightly
2.Holding on to the handle, pull the con-
vertible top forward onto the windshield
frame
3.Turn the handle until it audibly engages.
The convertible top is locked.
At higher speeds, the passenger
compartment may develop relatively
low air pressure, which can cause the con-
vertible top to begin fluttering. Increase the
air supply so that low pressure does not
occur in the vehicle.<
Fully automatic convertible
top*
The fully automatic convertible top com-
bines assured protection against the ele-
ments 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 pas-
senger compartment from unforesee-
able damage from the weather, but also
affords a degree of protection against
theft. In addition, only keep valuables in
the locked luggage compartment, even
with the convertible top closed
>Never mount a roof-mounted luggage
rack system on the convertible top.
>To prevent damage, do not operate the
convertible top at temperatures below
147/–106.Never store the convertible top while
it is wet to avoid permanent damage
from moisture.
Driving when the opening or closing pro-
cess has not been completed can cause
vehicle damage or personal injury.
Do not lay objects on the convertible top,
since they could fall off when the convert-
ible top is operated and cause damage or
injuries.
Do not reach into the convertible top mech-
anism during opening and closing. Keep
children away from the moving parts of the
convertible top during operation.<
If possible, only operate the convert-
ible top with the vehicle stopped, as
otherwise the process may be interrupted.
If you set the convertible top in motion
while the vehicle is stationary and then
have to start suddenly, for instance at a
traffic light, you can still complete the pro-
cedure by driving as slowly as possible and
again holding the corresponding button
pressed.<
At higher speeds, the passenger
compartment may develop relatively
low air pressure, which can cause the con-
vertible top to begin fluttering. Increase the
air supply so that low pressure does not
occur in the vehicle. 1To close
2To open
If at all possible, only operate the con-
vertible top if the engine is running.
This saves unnecessary battery wear.

Installation
Insert the wind deflector in its proper orien-
tation into the guides 1 provided on the
rollover bars.
Refer to the labeling on the wind deflector
to determine its proper orientation.
The wind deflector must engage
firmly, as it could otherwise become
detached at higher vehicle speeds.<
The wind deflector panels 2 in the rollover
bars cannot be removed.
Removal
Slide both locks inward and remove the
wind deflector.
Clothes hooks
Clothes hooks 1 are located on the wind
deflector panels in the rollover bars.Do not hang heavy objects on the
hooks. If you do, they could endanger
the passengers, for example during braking
or evasive maneuvers.<
Storage
For storage, e.g. to achieve a better view to
the rear when the convertible top is closed,
there are two brackets on the inside of the
luggage compartment lid.
Insert the wind deflector into the brackets.
Make sure that the wind deflector
cannot be damaged by objects in the
luggage compartment.<
Alarm system*
The concept
The vehicle alarm system responds:
>When a door, the hood or the luggage
compartment lid is opened
>When attempts are made to start the
vehicle
>To movement inside the vehicle
>To alterations in the vehicle tilt, e.g. as
would occur during attempts to steal
the wheels or tow the vehicle
>To interruption of battery voltage.
The alarm produced by the system in the
event of unauthorized vehicle entry and
attempted theft depends on the country
version:
>Sounding of an acoustical alarm for
30 seconds
>Activation of the hazard warning flash-
ers for approx. five minutes.

Arming and disarming the alarm
system
When the vehicle is locked or unlocked
either via the driver's door lock or with the
remote control, the alarm system is simul-
taneously armed or disarmed.
The hazard warning flashers blink once
when the alarm system has been properly
armed.
You can have different acknowledg-
ment signals set to confirm arming
and disarming.<
You can still open the luggage compart-
ment lid when the system is armed by
pressing the remote control button, refer to
page 17. When it is closed, the lid is once
again secured.
Manual operation of the luggage
compartment lid triggers the alarm.
Refer to page 19.<
To cancel an alarm:
Press the button on the remote control,
refer to page 16, or turn the ignition key to
position 1. Refer to page 36.
Indicator lamp displays
>The indicator lamp beneath the interior
mirror flashes continuously:
The system is armed
>The indicator lamp flashes when it is
being armed:
A door, the hood or luggage compart-
ment lid is not completely closed. Even
if you do not close the area causing the alert, the remaining areas are secured
and the indicator lamp flashes continu-
ously after 10 seconds.
However, the interior motion sensor is
not activated
>If the indicator lamp goes out as soon
as the system is disarmed:
No manipulation or attempted intru-
sions have been detected in the period
since the system was armed
>If the indicator lamp flashes for
10 seconds when the system is being
disarmed:
An attempted entry has been detected
in the period since the system was
armed.
After an alarm has been triggered, the indi-
cator lamp will flash continuously.
Interior motion sensor*
The system monitors the footwells and the
seating areas of the driver and passenger.
Deactivate the interior motion sensor,
refer to Avoiding unintentional alarms,
if children or animals are to remain in the
vehicle.<
Avoiding unintentional alarms
The tilt alarm sensor and interior motion
sensor can be deactivated at the same
time. You can do this to prevent a false
alarm from being triggered, for instance in
garages with elevator ramps or when the
vehicle is transported by train.
Lock the vehicle twice = arm the system:
Press the button on the remote control
twice in succession,
or
lock the vehicle twice with the key. Refer to
page 18.
The indicator lamp lights up briefly and
then flashes continuously. The tilt alarm
sensor and the interior motion sensor are
deactivated as long as the system is
armed.

Adjustments
Safe seating position
For relaxed driving with as little fatigue as
possible, you should select a seating posi-
tion that reflects your personal require-
ments. In combination with the safety belts
and airbags, the correct seating position
also plays an important role in enhancing
occupant safety in the event of an accident.
To ensure that the vehicle's safety systems
provide you with optimal protection, we
request that you direct your careful atten-
tion to the following section.
For supplementary information on trans-
porting children refer to page 33.
Sitting safely with airbags
Always maintain an adequate dis-
tance between yourself and the air-
bags. Always hold the steering wheel by its
rim with hands at the 9 and 3 o'clock posi-
tions to minimize the risk of injuries to your
hands or arms in the event of airbag
deployment.
Never allow any objects, individuals or ani-
mals to obstruct the areas between pas-
sengers and airbags.
Never use the front airbag's cover as a
storage tray or support for objects of any
kind. Ensure that the passenger is correctly
seated, i.e. that no feet or legs are propped
against the dashboard. Otherwise, leg
injury could result if the knee airbag and
front airbag suddenly deployed.
Never let an occupant's head rest near or
on a side airbag because the inflating air-
bag could cause a serious or fatal injury.<
Even when all these guidelines are
observed, the risk of injury as a result of
contact with the airbags cannot entirely be
ruled out in some situations. In sensitive
individuals, the ignition and inflation noise
may induce a mild hearing loss that is tem-
porary in most cases.
For airbag locations and additional infor-
mation on airbags, refer to page 56.
Sitting safely with safety belts
Always fasten your safety belt before start-
ing off. As supplemental restraint devices,
the airbags are designed to enhance the
effectiveness of the safety belts, and not to
replace them.
Your vehicle offers two sitting positions,
each of which is equipped with a safety
belt.
At all times, occupants should sit
upright and be properly restrained –
infants and small children in appropriate
child-restraint systems; larger children and
adults using the safety belts.
Expectant mothers should always wear
their safety belts, taking care to position
the lap belt against the lower hips, where it
will not exert pressure against the abdomi-
nal area.
Never allow more than one person to wear
a single safety belt. Never allow infants or
small children to ride in a passenger's lap.
Do not route the belt across your neck, or
run it across sharp edges. Be sure that the
belt does not become caught or jammed.
Avoid twisting the belt while routing it firmly
across the hips and shoulder; wear it as
snugly against your body as possible. Do
not allow the belt to rest against hard or
fragile objects. Otherwise, the lap belt
could slide over the hips in the event of a
frontal impact, leading to abdominal injury.
Avoid wearing bulky clothing and pull on
the lap belt periodically to retension it over
your shoulders. Otherwise, the restraining
effect of the safety belt could be dimin-
ished.<
For information on using the safety belts,
refer to page 30.
