Opening and closing – via the remote controlThe conceptThe remote control gives you an excep-
tionally convenient method for unlock-
ing and locking your vehicle. Further-
more, it provides two additional
functions:
>Switch on the interior lamps, refer to
page 32.
With this function you can also
search for your vehicle – when
parked in an underground garage, for
instance
>Open the luggage compartment lid,
refer to page 32.
The luggage compartment lid will
open slightly, regardless of whether it
was locked or unlocked.
The anti-theft system is also deacti-
vated/activated simultaneously with the
unlocking or locking of the vehicle, and
the alarm system is disarmed/armed,
and the interior lamps are switched
on/off.
You can have a signal set to con-
firm that the vehicle's locks have
engaged securely.<
Master keys with remote control
Since passengers or animals
remaining in the vehicle might be
able to lock the doors from the inside,
always take the vehicle's keys with you
so that the vehicle can be opened again
from the outside at any time.<
If it is no longer possible to lock
the vehicle via the remote control,
the battery is discharged. Use this key
while driving for an extended period in
order to recharge the battery. Guard
the remote control against unauthorized
use by only surrendering the spare key
or the door and ignition key, e.g. for
valet parking.
In the event of a system malfunction,
please contact your BMW center. You
can also obtain replacement keys
there.<

>To movement inside the vehicle –
interior motion sensor
>Altering the vehicle tilt, e.g. as would
occur while attempting to steal the
wheels or tow the vehicle – tilt alarm

The system responds to unauthorized
vehicle entry and attempted theft by
simultaneously activating the following:
>Sounding an acoustic alarm for
30 seconds
>Activating the hazard warning flash-
ers for approx. five minutes
>Flashing the high beams on and off in
rhythm with the hazard warning flash-
ers.To arm and disarm the alarm
systemWhen the vehicle is locked or unlocked
by using a key or with the remote con-
trol, the alarm system is also simulta-
neously armed or disarmed.You can have a signal set as
acknowledgment for both arming
and disarming the alarm.<
You can also open the luggage com-
partment lid when the system is armed

Driving with the opening or clos-
ing operation not completely
ended can lead to damage and/or inju-
ries.
Traffic laws applicable in your area take
precedence when you operate the con-
vertible top, otherwise you may be
breaking the law.
Do not lay objects on the convertible
top, since they would fall off when the
convertible top is operated and cause
damage or injuries.
Do not reach into the convertible top
mechanism during opening and closing.
Keep children away from the moving
parts of the convertible top during
operation.<
If possible, only operate the con-
vertible top with the vehicle
stopped, as otherwise the process may
be interrupted.
If you set the convertible top in motion
with the vehicle stationary and then
have to start suddenly – for instance, at
a traffic light – you can still complete
the operation by driving as slowly as
possible and again pressing and main-
taining pressure on the button.
Before closing the convertible top,
remove any objects from the windshield
frame that could keep the convertible
top from closing properly.<
To close the electric power win-
dows while driving, always be
sure to first close either the rear win-
dows, or all 4 windows at the same
time, otherwise, at high speed, the win-
dows may not close tightly.<
At higher speeds, the ensuing
vacuum in the passenger com-
partment can cause the convertible top
to begin fluttering. Increase the air sup-
ply via the ventilation controls so that a
vacuum does not occur in the vehicle.<

safety precautions

make sure that the convertible top
compartment panel in the luggage
compartment is lowered, refer to
page 37

If there is a system malfunction, there is
a risk that the airbags will not be trig-
gered within their normal response
range, even if the level of impact would
normally have triggered them.
Have your BMW center inspect the sys-
tem immediately.
Transporting children safely
Leave the rear safety belts in the
holders if they are not needed to
avoid unwanted movement from the
safety belts at high speeds.<
Commercially available child seats
complying with the legal standard are
designed to be secured with a seat belt
or with the seat belt portion of a combi-
nation lap/shoulder belt. Improperly or
inadequately installed restraint sys-
tems can increase the risk of injury to
children. Always read and follow the
instructions that come with the system.
Child-restraint system with tether
strapIf you use a child-restraint system with
a tether strap, two additional tether
anchorage points have been provided –
refer to the arrows in the illustration.

Depending on the location selected for
seating in the rear passenger area,
attach the tether strap to the corre-
sponding anchorage point to secure the
child-restraint system, as shown in the
illustration.
1. Open the convertible top compart-
ment lid, refer to page41
2. Lift the headrest and pass the tether
strap between the headrest and the
seat back. It is recommended that
you return the head restraint back to
its lowest possible position
3. Adjust the tether strap according to
the child-restraint manufacturer's
instructions
4. Close the convertible top compart-
ment panel.
It is recommended to cover the child-
restraint attaching clip with a soft mate-
rial to prevent damage to the stored
soft top.
Should a hard top be installed, the
fitting of child harness tether
strap/s – if child seat is required – is
necessary before installation of the
hard top.<
Before installing any child-
restraint device or child seat,
please read the following:
Never install a rearward-facing child-
restraint system in the front passenger
seat of this vehicle.
Your vehicle is equipped with an airbag
supplemental restraint system for the
front passenger. Because the backrest
on any rear-facing child-restraint sys-
tem – of the kind designed for infants
under 1 year and 20 lbs/9 kg – would
be within the airbag's deployment
range, you should never mount such a
device in the front passenger seat, as
the impact of the airbag against the
child-restraint's backrest could lead to
serious or fatal injuries.
If it is necessary for a child – not an
infant – to ride in the front seat, certain
precautions should be taken. First,
move the passenger seat as far away
from the instrument panel as possible.
This important precaution is intended to
maximize the distance between the air-
bag and the child. Older children
