Convenient operation
For information on Convenient operation via the
remote control or the door lock, refer to page27
or30. For information on Convenient closing
with Comfort Access, refer to Locking on
page28.
Pinch protection system
If the closing force exceeds a specific value as a
window closes, the closing action is interrupted
and the window reopens slightly.
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 that might inter-fere with window movement. Otherwise, the
pinch protection system could be impaired.
Convertible: the rear windows are not equipped
with pinch protection. Therefore, watch them
closely when closing to avoid personal injury.<
Closing without pinch protection
If there is an external danger, or if ice on the win-
dows, etc., prevents you from closing the win-
dows normally, proceed as follows:
1.Pull the switch past the resistance point and
hold it there. Pinch protection is limited and
the window reopens slightly if the closing
force exceeds a certain value.
2.Pull the switch again past the resistance
point within approx. 4 seconds and hold it
there. The window closes without pinch
protection.
Coupe: glass roof*, electric
To prevent injuries, watch the glass roof
while closing it.
Take the remote control with you when you
leave the car; otherwise, children could operate
the roof and possibly injure themselves.<

Pull button: close the retractable hardtop.
2LEDs
The side windows move down when the
switch for hardtop operation is pulled or
pushed.<
LEDs
In the following situations, a message appears
on the Control Display or an acoustic signal
sounds in addition to the LED lighting up:
>While the hardtop is being operated, the left
LED lights up green. It goes out as soon as
the top is fully opened or closed.
>If the right-hand LED flashes red when you
release the switch, the opening or closing
action has not yet finished.
>If the right LED lights up red when the
switch is pressed, the cargo area partition is
folded up, the trunk lid is not closed, the
vehicle is standing on a strong incline or
there is a malfunction. The retractable hard-
top cannot be moved.
Interruption
The automatic sequence of movements is
interrupted if the switch for hardtop operation is
released. The sequence can be continued in
the desired direction by pushing or pulling the
switch.
A hardtop that is not fully opened or
closed is a safety hazard.

dure several times in close succession as this
could damage the mechanism.<
If the hardtop is not fully opened or
closed, the trunk lid cannot be opened
and the windows cannot be moved.<
Convenient operation with remote
control or via door lock
Refer to pages28 and30.
Wind deflector*
The wind deflector keeps air movements in the
passenger compartment to a minimum when
the hardtop is open and provides an even more
comfortable ride, particularly at high speeds.
Installation
The wind deflector is stored in a protective
cover in the cargo area. Brief instructions for

Airbags
The following airbags are located under the
marked covers:
1Front airbags
2Coupe: head airbags
3Side airbags in the seat backrests
4Convertible: knee airbags
Protective action
Observe the adjustment instructions on
page42 to ensure the best possible per-
sonal protection.<
The front airbags help protect the driver and
front passenger by responding to frontal
impacts in which safety belts alone cannot pro-
vide adequate restraint. When needed, the
head and side airbags help provide protection in
the event of side impact. The relevant side air-
bag supports the side upper body area. The
head air bag supports the head.
The airbags have been designed to not be trig-
gered in every collision situation, e.g. not in
minor accidents or rear-end collisions.
Do not apply adhesive materials to the
cover panels of the airbags, cover them or
modify them in any other way.
Keep the dashboard and windows on the front
passenger side clear, i.e. do not cover with
adhesive labels or coverings, and do not attach
holders such as for navigation instruments or
mobile phones.
Do not attach seat covers, cushions or other
objects not specifically approved for seats with
integral side airbags to the front seats. Do not
hang items of clothing such as coats or jackets over the backrests. Do not attempt to remove
the airbag retention system from the vehicle. Do
not modify the individual components of the
system or its wiring in any way. This includes
the upholstered covers on the steering wheel,
instrument panel, seats and roof posts, as well
as the sides of the roof lining. Do not attempt to
remove or dismantle the steering wheel.
Do not touch the individual components imme-
diately after the system has been triggered,
because there is a danger of burns.
In the event of malfunctions, deactivation or
triggering of the airbag restraint system, have
the testing, repair, removal and disposal of air-
bag generators executed only by a BMW center
or a workshop that works according to repair
procedures of BMW with correspondingly
trained personnel and that has the required
explosives licenses. Unprofessional attempts to
work on the system could lead to failure in an
emergency or to undesired airbag activation,
either of which could result in personal injury.<
Warning notices and information about the air-
bags can also be found on the sun visors.
Automatic deactivation of the front
passenger airbags
An analysis of the impression in the front pas-
senger seat cushion determines whether and
how the seat is occupied. The front and side air-
bags for the front passenger are activated or
deactivated by the system accordingly.
The indicator lamp above the interior
rearview mirror shows the current status
of the front passenger airbags, deactivated or

100 automatic climate control is optimized for driv-
ing with the hardtop open. In addition, the air
volume is increased as vehicle speed increases.
The effectiveness of the Convertible pro-
gram can be enhanced considerably by
installing the wind deflector.<
Adjusting air volume manually
To be able to manually adjust the air volume,
switch off the AUTO program first.
Press the left side of the button to
reduce the air volume. Press the
right side of the button to increase
it.
The air volume may be reduced or the blower
may be switched off entirely to save on battery
power. The display remains the same.
Automatic recirculated-air control
AUC/Recirculated-air mode
You can respond to unpleasant odors or pollut-
ants in the immediate environment by tempo-
rarily suspending the supply of outside air. The
system then recirculates the air currently within
the vehicle.
Press the button repeatedly to
select an operating mode:
>LED off: outside air flows in continuously.
>Left-hand LED on, AUC mode: a sensor
detects pollutants in the outside air and
controls the shut-off automatically.
>Right-hand LED on, recirculated-air mode:
the supply of outside air is permanently
shut off. If the windows fog over, switch off
recirculated-air mode and increase the air
volume, if necessary. Make sure that air can
flow onto the windshield.
The recirculated-air mode should not be
used over an extended period of time;
otherwise, the air quality inside the car will dete-
riorate continuously.<
Via the button on the steering wheel
You can switch quickly between the recircu-
lated-air mode and the previous mode using a
button
on the steering wheel, refer to page11.

Things to remember when driving
118
Things to remember when driving
Break-in period
Moving parts need breaking-in time to adjust to
each other. Please follow the instructions below
in order to achieve the optimal service life and
economy of operation for your vehicle.
Engine and differential
Always obey all official speed limits.
Up to 1,200 miles/2,000 km
Drive at varying engine and road speeds, but do
not exceed an engine speed of 4,500 rpm or a
road speed of 100 mph/160 km/h.
Avoid full-throttle operation and use of the
transmission's kickdown mode.
After driving 1,200 miles/2,000 km
Engine and vehicle speeds can be gradually
increased.
Tires
Due to technical factors associated with their
manufacture, tires do not achieve their full trac-
tion potential until after an initial break-in
period. Therefore, drive cautiously during the
first 200 miles/300 km.
Brake system
Brakes require an initial break-in period of
approx. 300 miles/500 km to achieve optimized
contact and wear patterns between brake pads
and rotors. Drive cautiously during this break-in
period.
Clutch
The function of the clutch reaches its optimal
level only after a distance driven of approx.
300 miles/500 km. During this break-in period,
engage the clutch gently.
Following part replacement
The same break-in procedures should be
observed if any of the components mentioned
above have to be renewed in the course of the
vehicle's operating life.
Saving fuel
The fuel consumption of your vehicle depends
on several factors. You can lower fuel consump-
tion and the environmental impact by taking
certain measures, adjusting your driving style
and having the vehicle serviced regularly.
Remove any unneeded cargo
Additional weight increases fuel consumption.
Remove any mounted parts after you
have finished using them
Remove unneeded additional mirrors, the roof
rack and the rear luggage rack after use.
Mounted parts affect the vehicle's aerodynam-
ics and increase fuel consumption.
Close the windows and glass roof
An open glass roof or window causes higher air
resistance and thus increases fuel consump-
tion.
Check tire inflation pressure regularly
Check the tire inflation pressure at least twice a
month and before embarking on a long journey,
and correct it if necessary.
Low tire inflation pressure causes higher rolling
resistance and thus increases fuel consumption
and tire wear.
Set off immediately
Do not let the engine warm up while the car is
still standing, but set off immediately at moder-
ate engine speed. This is the fastest way for the
cold engine to reach its operating temperature.

Mobility
Drive defensively
Avoid unnecessary acceleration and braking
maneuvers. To do so, keep an adequate dis-
tance between you and the vehicle in front of
you. A defensive and smooth driving style
keeps fuel consumption down.
Avoid high engine speeds
Only use first gear when setting off. In second
and higher gears, accelerate without hesitation
or pauses. When accelerating, shift up before
reaching high engine speeds.
When you reach the desired speed, shift into
the highest applicable gear and drive with the
engine speed as low as possible and at a con-
stant speed.
As a rule: driving at low engine speeds lowers
fuel consumption and reduces wear.
Coasting
When approaching a red light, take your foot off
the accelerator and coast to a stop in the high-
est applicable gear.
O n a d o w n h il l s lo p e , t a k e y o u r f o o t o f f t h e a c c el -
erator and coast in a suitable gear.
The fuel supply is interrupted when coasting.
Switch off the engine during lengthy
stops
Switch off the engine when stopping for lengthy
periods, e.g. at traffic lights, railroad crossings
or in traffic congestions. You achieve fuel sav-
ings even if standing time is as short as approx.
4 seconds.
Switch off functions you do not need at
the moment
Functions such as the air conditioner, seat
heating or rear window defroster draw large
amounts of power and consume additional fuel.
Especially in city traffic and in stop and go driv-
ing they have a considerable impact. Therefore,
switch these functions off when they are not
really needed.
Have the vehicle serviced
Have the vehicle serviced regularly to achieve
good economy and a long vehicle life. BMW
recommends having the vehicle serviced at a
BMW center. Also note the BMW service sys-
tem, refer to page217.
General driving notes
Close the trunk lid
Operate the vehicle only when the trunk
lid is closed. Otherwise, exhaust fumes
could enter the interior of the vehicle.<
If the vehicle must be driven with the trunk lid
open:
1.Close all windows and the glass roof.
2.Greatly increase the air volume of the auto-
matic climate control system, refer to
page100.
Hot exhaust system
In all vehicles, extremely high tempera-
tures are generated in the exhaust sys-
tem. Do not remove the heat shields installed
adjacent to various sections of the exhaust sys-
tem, and never apply undercoating to them.
When driving, standing at idle and while park-
ing, take care to avoid possible contact
between the hot exhaust system and any highly
flammable materials such as hay, leaves, grass,
etc. Such contact could lead to a fire, with the
risk of serious personal injuries and property
damage. Do not touch hot exhaust tail pipes.
Otherwise, there is a risk of burns.<
Hydroplaning
When driving on wet or slushy roads,
reduce road speed. If you do not, a wedge
of water can form between tires and road sur-
face. This situation, known as hydroplaning,
means that the tire can completely lose contact
with the road surface, so that neither the car can
be steered nor the brake be properly applied.<
