Convertible: rollover
protection system
The rollover protection system is activated
automatically in the event of an accident, a crit-
ical driving situation, an extreme tilt in the car's
longitudinal axis or upon loss of ground contact.
The protection bars behind the rear head
restraints deploy within fractions of a second.
As a supplementary system to the reinforced
windshield frame, the rollover protection sys-
tem ensures that the necessary headroom is
maintained for all vehicle occupants.
Always keep the area of movement of the
rollover protection system clear.
In minor accidents, you are protected by the
fastened safety belt and, depending on acci-
dent severity, by the safety belt tensioner and
multi-phase airbag retention system.<
Resetting
If the rollover protection system was not
impacted after being automatically activated, it
can be reset by lowering the protection bars to
their original positions. This does not require
tools.
1.Push the locking lever to one side and hold
it there.
2.Push the protection bar halfway down from
above.
3.Release the locking lever.4.Push the protection bar down until it snaps
into place.
5.Repeat the procedure for the other protec-
tion bar.
Have the rollover protection system checked
after an unexpected activation.
Never move the retractable hardtop when
the rollover protection system is in the
activated position.
Do not make any modifications to the individual
components of the rollover protection system
or its cabling.
Work on the rollover protection system should
only be performed by a BMW center.
Incorrectly performed work on the system may
lead to system failure or incorrect operation.
To check the system and ensure flawless long-
term operation, always observe the service
intervals, refer to page80.<

Climate
108
Convertible program
The Convertible program is active when the
hardtop is open and the AUTO program is
switched on. In the Convertible program, the
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.
ALL program
Press the button.
The current temperature setting
on the driver's side is transferred to
the front passenger side.
If the temperature setting on the driver's side is
changed, the temperature on the front passen-
ger side is changed as well.
The program is switched off when the setting is
adjusted on the front passenger side or the but-
ton is pressed again.
Defrosting windows and removing
condensation
Press the button.
Quickly removes ice and conden-
sation from the windshield and
front side windows.
For this purpose, also switch on the cooling
function.
Switching cooling function on/off
The passenger compartment can only be
cooled while the engine is running.
Press the button.
The air is cooled and dehumidified
and – depending on the tempera-
ture setting – warmed again.
Depending on the weather, the windshield may
fog up briefly when the engine is started.
Pressing the AUTO button automatically
switches on the cooling function.
Rear window defroster
Press the button.
The defroster is switched off auto-
matically after a certain time.
Depending on your vehicle's equipment, the
upper wires serve as an antenna and are not
part of the rear window defroster.

Enlarging the cargo area
When the hardtop is closed you can enlarge the
cargo area:
To do so, push the cargo area partition upward.
Before opening the hardtop, push the cargo
area partition down until it engages on both
sides.
Before moving the hardtop, ensure that
there are no objects on or next to the
cargo area partition; otherwise, parts of the
hardtop may be damaged. Do not exceed the
maximum loading height; refer to the sticker in
the cargo area showing a line indicating the
maximum height. Do not use force to push
down the cargo area partition.<
The retractable hardtop can only be
opened if the cargo area partition is in its
lowermost position and engaged on both
sides.<
Folding down the rear seat backrest
Opening
You can fold down the rear seat backrest to
transport light objects in the rear without dam-aging the seats. Depending on the vehicle
equipment, the mounting points for the cargo
area net
* are found on the back of the seat
backrest. To unlock the rear seat backrest:
press the button on the driver's or the opposite
side.
Closing
Return the rear seat backrest to the upright
seating position and engage it.
When returning the backrest to its seating
position, make sure that the seat's lock-
ing mechanism engages properly. Otherwise,
cargo could be thrown around in the event of
sharp braking or swerving and endanger the
occupants.<

1.Fold open the holder by pressing the but-
ton.
2.Press the handles of the bag onto the
holder from above.
Only hang light shopping bags or other
suitable objects from the holders; other-
wise, braking maneuvers and swerving, for
example, may lead to a safety hazard due to
objects flying about the passenger compart-
ment. Only transport heavy luggage in the
cargo area if it has been appropriately
secured.<
For more information on loading the vehicle,
refer to page129.

Care
230
Sports automatic transmission with
double clutch
Before driving into an automatic car wash, per-
form the following steps to ensure that the vehi-
cle can roll:
1.Insert the remote control into the ignition
lock, even with Comfort Access.
2.Engage transmission position N.
3.Release the parking brake.
4.Switch off the engine.
5.Leave the remote control in the ignition lock
so that the vehicle can roll.
The transmission is switched into position P:
>automatically after approx. 30 minutes
>if you remove the infrared remote control
from the ignition lock
Steam jets/high-pressure washers
When using steam jets or high-pressure
washers, ensure that you maintain suffi-
cient clearance to the vehicle and do not exceed
a temperature of 1407/606.
Insufficient clearance or excessive pressure or
temperature can lead to component damage or
water penetration. Follow the operating instruc-
tions of the high-pressure washer.<
When using high-pressure washers, do
not spray against the sensors and cam-
eras, e.g. of the Park Distance Control or Rear
View Camera, for an extended period and main-
tain a distance of at least 1 ft/30 cm.<
Manual car wash
When washing the vehicle by hand, use large
quantities of water and car shampoo if neces-
sary. Clean the vehicle with a sponge or wash-
ing brush, applying light pressure only.
Before cleaning the windshield, deacti-
vate the rain sensor or switch off the igni-
tion to prevent unintentional activation of the
wipers.<
Observe local regulations pertaining to
washing vehicles by hand.<
Headlamps
Do not rub them dry and do not use abrasive or
corrosive cleaning agents.
Loosen dirt, e.g. insects, with shampoo or
insect remover and wash away with copious
quantities of water.
Thaw ice with a windshield deicer and do not
use an ice scraper.
Windows
Clean the inside and outside surfaces of the
windows and the mirrors with window cleaner.
Do not clean the mirrors with cleaners
containing quartz.<
Convertible: retractable hardtop
Proceed as you would in a normal car wash.
When you open a wet hardtop, water
drops may run into the cargo area. If nec-
essary, remove items from the cargo area
beforehand to avoid water stains or soiling.<
Paintwork care
Regular care contributes to value retention and
protects the paintwork against the long-term
effects of damaging substances.
Region-specific environmental influences can
damage the vehicle paintwork. Therefore, it is
important to adapt the frequency and scope of
car care accordingly.
Immediately remove aggressive materials such
as spilled fuel, oil, grease, brake fluid, tree sap or
bird droppings to prevent damage to the paint-
work.
Repairing paintwork damage
Immediately repair scratches or similar
damage, such as that caused by stones
hitting the vehicle, where necessary to prevent
rusting.<
BMW recommends having paintwork damage
repaired by a professional paint repair work-
shop according to BMW specifications using
original BMW paint materials.
