Opening, closing
Ignition key in position 1 or higher:
>Press the switch downward to the resis-
tance point.
The window continues to open as long as
you press the switch.
>Press the switch beyond the resistance
point.
The window opens automatically. Press the
switch again to stop the opening move-
ment.
You can close the window in the same manner
by pulling the switch upward.
If you wish, you can have this special fea-
ture activated/deactivated.<
After switching off the ignition
You can still open or close the windows for
approx. 1 minute, as long as no one opens any
of the doors.
For convenience operation via the remote con-
trol or the door lock, refer to page19 or20,
respectively.
Pinch protection system
If the closing force exceeds a certain value while
a window is being raised, the system responds
by stopping the window and then retracting it a
short distance.
Despite the pinch protection system
check and clear the window's travel path
prior to closing it, otherwise the safety system
might fail to detect certain kinds of obstruc-
tions, such as thin objects, and the window
would continue closing.
Do not install any accessories within the win-dows' range of movement; otherwise the pinch
protection system could be impaired.<
The closing force can change as a result
of extreme temperature fluctuations. The
window then opens slightly after closing even if
there is no obstacle within the window's travel
path. If this occurs, override the pinch protec-
tion system.<
Pulling the switch beyond the resistance point
and holding it there overrides and deactivates
the pinch protection system.
After a power supply interruption
After a power supply interruption, for instance
after disconnecting the battery, the pinch pro-
tection system must be reinitialized.
Roadster: when the convertible top has
been stored in the convertible top com-
partment for an extended period of time, e.g. in
the winter months because the hardtop was
being used, it may also be necessary to reinitial-
ize the pinch protection system.<
Ensure that the doors and the Roadster's con-
vertible top are closed before initializing.
1.Open the window completely.
2.Press the switch 4 times within approx.
10 seconds.
Afterward, perform the following procedure
twice for each window:

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.<

Safety belts
Comply with the instructions on page30,
or the occupants' personal safety will be
diminished.<
Make sure every occupant fastens his or her
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
buckle.
The upper belt anchor is suitable for adults of
any stature as long as the seat is adjusted prop-
erly, refer to page31.
To unlock

rectly.
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.

Transporting children safely

Transporting children safely
The right place for children
Do not leave children unattended in the
vehicle, otherwise they could endanger
themselves and/or other persons by opening
the doors, for example.<
Children on the passenger seat
Children under 13 years of age or under
5 ft/150 cm in height may only be trans-
ported in child-restraint systems suitable for
their age, weight and size and if the passenger
airbags are deactivated. Otherwise, there is an
increased risk of injury in the event of an acci-
dent or should the airbags deploy.<
Children 13 years of age or older must be buck-
led in with a safety belt as soon as there no
longer is any child-restraint system that is
appropriate for their age, weight and size.
For a child, not an infant, certain precautions
should be taken. Position the passenger seat as
far back as possible and at the lowest level. This
important precaution is intended to maximize
the distance between the airbags and the child.
Deactivating/reactivating passenger
airbags
The passenger airbags must be deacti-
vated before using a rear-facing child-
restraint system on the passenger seat, refer
also to page37 for explanation.
BMW also recommends that the passenger air-
bags be deactivated if a child is transported in a
front-facing child-restraint system, regardless
of the age of the child. If you transport a child in
the passenger seat, not an infant in a rear-fac-
ing seat, who is properly seated and seat-belted
at all times, the potential benefits of airbags
deploying in an accident generally outweigh the
risks of the child being injured by the force of a
deploying airbag.
Therefore, you should deactivate the passen-
ger airbags only if you find it difficult to ensure
that the child will remain properly seated and seat-belted at all times.
Always position the passenger seat as far back
as possible and at the lowest level.
The above warning and recommendations are
compatible with regulations established by the
National Highway Traffic Safety Administration,
NHTSA, permitting the deactivation of passen-
ger airbags by means of an on-off switch for
members of certain at-risk groups.
Specifically, the at-risk groups are:
>Infants in rear-facing infant seats
>Persons with certain medical conditions
>Children aged 12 and under in the passen-
ger seat.
NHTSA provides this information via their web-
site, www.nhtsa.dot.gov, or via their Auto
Safety Hotline toll-free at
1-800-424-9393 or 366-0123
in Washington, D.C. area.<
Key switch for passenger
airbags
The front, side and knee airbags for the passen-
ger can be deactivated and reactivated using a
key switch. It is located on the passenger side
on the side of the dashboard.
The passenger airbags can only be deactivated
and reactivated while the vehicle is at a stand-
still and the passenger door is open.

Deactivating
Use the key to turn the key switch to the OFF
position.
The passenger airbags are deactivated in this
position. The airbags for the driver remain
active.
Reactivate the passenger airbags as soon
as a child-restraint system is no longer
installed on the passenger seat; otherwise they
may not deploy as intended in the event of an
accident.<
Reactivating
Use the key to turn the key switch to the ON
position.
The passenger airbags in the vehicle are reacti-
vated and will be triggered in certain situations.
Operational status of the passenger
airbags
>The indicator lamp remains lit when the
passenger airbags are deactivated.
>The indicator lamp is not lit when the pas-
senger airbags are activated.
When the seat is empty, the passenger
airbags are always deactivated. The indi-
cator lamp is not lit.<
Installing child-restraint
systems
Before installing a child-restraint system
on the passenger seat, make sure that the
front and side airbags for the passenger are
deactivated, otherwise there is an increased
risk of injury if the airbags deploy. Observe the child-restraint system manufacturer's instruc-
tions for selecting, installing and using child-
restraint systems. Otherwise the protective
effect may be diminished.<
Child seat security
The passenger's safety belt can be prevented
from being pulled out in order to fasten child-
restraint systems.
To lock the safety belt
1.Secure the child-restraint system with the
belt.
2.Pull the belt strap all the way out.
3.Allow the belt strap to retract and pull it taut
against the child-restraint system.
The safety belt is locked.
To unlock the safety belt

Starting the engine
Engine idle speed is controlled by the engine
computer system. Increased speeds at start-up
are normal and should decrease as the engine
warms up. If engine speed does not decrease,
service is required.
To prevent the battery from discharging, always
deactivate electrical devices that are not in use.
Switch the ignition off when the vehicle is not
being driven.
Do not leave the engine running in
enclosed spaces. Otherwise, inhalation of
the hazardous exhaust gases could lead to
unconsciousness and death. The exhaust
gases contain carbon monoxide, an odorless
and colorless, but highly toxic gas. Do not leave
the vehicle unattended with the engine running.
An unattended vehicle with a running engine
poses a safety hazard.
Before leaving the car with the engine running,
place the transmission in idle or move the
selector lever to position P and apply the park-
ing brake to prevent the car from moving.<
When starting the engine, do not press the
accelerator pedal.
Do not end the starting procedure too early, but
do not continue it for more than 20 seconds.
Release the key immediately when the engine
starts.
Do not let the engine warm up in idling position.
Instead, begin to drive at moderate engine
speeds.
Vehicles with manual transmission:

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.
When you leave the vehicle, always remove the
key and engage the steering lock.
Apply the parking brake when parking on steep
gradients, otherwise the vehicle could start to
roll.<
You can have an acoustic signal set as a
reminder that the key is still in the ignition
switch after the driver's door has been
opened.<

If, in exceptional circumstances, it should
be necessary to engage the parking brake
while the vehicle is in motion, do not pull it with
excessive pressure. In doing so, continuously
press the button of the parking brake lever. Oth-
erwise, too violent an application of the parking
brake can overbrake the rear axle and cause the
rear of the car to swerve.<
To prevent corrosion and one-sided brak-
ing action, occasionally apply the parking
brake lightly when the vehicle is slowly coming
to a stop if the traffic conditions are suitable.
The brake lamps do not light up when the park-
ing brake is applied.<
