Luggage compartment lid To unlock from inside Press on the upper half of the button
(luggage compartment lid symbol).
The luggage compartment lid opens
slightly.
This button will not open the
luggage compartment lid if the
glove compartment is locked. Refer to
page 78.<520de012
To open from outsideReach into the recess and open the
luggage compartment lid all the way.
The luggage compartment is illumi-
nated when the lid is opened. Manual operation Should the electrical system malfunc-
tion, the luggage compartment lid can
be opened from the inside. Refer to
page 140. To close The luggage compartment is locked
again as soon as you close the lid.520us017
As with all closing procedures, be
sure that the travel path for the
luggage compartment lid is clear when
being closed to avoid injury.
Keep the luggage compartment lid
closed while driving so that no exhaust
fumes will penetrate to the inside of the
vehicle. If, however, the luggage
compartment lid has to stay open and
the convertible top is closed while
driving,
>close all the windows
>increase the air supply from the
heating and ventilation system to a
high level. Refer to page 72.<

Heating and ventilation/Air conditionerAir supply
You can select blower speeds
from 1 to 4. The higher the
setting, the greater the
amount of heat and air supply.
In position 0, the blower, heating and air
conditioner are switched off.
Temperature
In order to increase the inte-
rior temperature, turn to the
right. For rapid heating, turn
completely to the right. Then
select an interior temperature that is
comfortable for you.
Air distribution
You can direct the airflow onto
the windows , toward the
upper body and into the
footwell . You can also make
all intermediate settings. The "6 o'clock"
setting is recommended for normal
conditions (refer also to the illustration
and overview on page 72).
Recirculated air mode
If there are unpleasant odors
in the incoming air, you can
temporarily block the air
supply. The system then recir-
culates the air already within the
vehicle.
If condensation starts to form on
window surfaces during opera-
tion in the recirculated-air mode, switch
it off and return the ventilation system
to the incoming air mode; turn up the
blower and select the defroster if
necessary to clear the windows.<
Incoming air mode
Recommended when driving
with the convertible top open.
The degree to which the
passenger compartment is
heated depends on temperature selec-
tion and air distribution.
Air conditioner/incoming air mode
The air is cooled and dehu-
midified and Ð depending on
the temperature setting Ð
warmed again when the air
conditioner is switched on. Depending
on the weather, the windshield may fog
over briefly when the engine is started.
Do not turn on the air conditioner if the
outside air temperature is below
approx. 41 7 (5 6). This will help to
prevent the windows from fogging.
If the windows fog over after switching
the air conditioner off, switch it back on.
Air conditioner/Recirculated air
mode
You may find it useful to acti-
vate both systems to cool the
car more rapidly after it has
been parked with the top up
on a hot day. This setting provides the
coldest possible airflow from the vent
outlets (with temperature selection
switch turned all the way to the left).

Heating and ventilation/Air conditioner
If condensation starts to form on
window surfaces during operation
in the recirculated-air mode, switch it
off and return the ventilation system to
the incoming air mode; turn up the
blower and select the defroster if
necessary to clear the windows.<
To defrost windows and remove
condensation
This operation quickly
removes ice and condensa-
tion from the windshield and
the side windows.
Rear window defroster
Whenever the hardtop is on,
the indicator lamp lights up
when the rear window
defroster is turned on. The rear window
defroster switches off automatically.
Refer to page 60.
The indicator lamp is always
active, however the rear window
defroster will not work if the hardtop is
not in place.<
Draft-free ventilation You can adjust the air outlets for the
upper body area for your personal
comfort:
Use rotary dials 1 to open and close the
air outlets through an infinitely-variable
range.520de043
You can adjust the direction of the
airflow using the levers 2.
Set the air outlets so that the air flows
past you and is not directed straight at
you.MicrofilterThe microfilter removes dust and pollen
from the outside air. Your BMW center
will change this filter during routine
maintenance. A substantial reduction in
air flow indicates that the filter needs to
be replaced early.520de140

Brakes:
Do not rest your foot on the brake
pedal while driving. Even light but
consistent pressure on the brake pedal
could lead to high temperatures, brake
wear, and possibly, to brake system
failure.
Aquaplaning:
Reduce speed while driving on wet or
slushy roads, otherwise, a wedge of
water can form between the tires and
the road surface. This phenomenon is
referred to as "aquaplaning" or "hydro-
planing." It is characterized by a partial
or complete loss of contact between
the tires and the road surface. The ulti-
mate results are loss of steering and
braking control.
Driving through water:
When there is water on the roads, do
not drive in it if it is deeper than 1 ft
(30 cm), and even then, only at walking
speed, otherwise the vehicle can
sustain damage to the engine, the elec-
trical systems and the transmission.<
The catalytic converter reduces harmful
exhaust emissions.
It is designed for use with unleaded fuel
only. Even minute quantities of lead
would be enough to permanently
damage both the catalytic converter
and the system oxygen sensor.To ensure efficient, trouble-free engine
operation and to avoid potential damage:>Be sure to comply with the scheduled
maintenance requirements
>Fill the fuel tank well before it is empty
>Tow-start only when the engine is
cold. If you attempt to tow-start with
a warm engine, unburned residual
fuel in the catalytic converter could
ignite and cause damage. It is better
to start the vehicle with a battery
charger or assistance from another
vehicle
>Avoid other situations where the fuel
is either not burned or burns incom-
pletely, such as engaging the starter
frequently or for extended periods, or
repeated start attempts in which the
engine does not start (stopping and
restarting an engine which is running
properly does not present a pro-
blem). Never allow the engine to run
with any of the spark plug cables
disconnected.Be sure to comply with the
instructions above to prevent
unburned fuel from reaching the cata-
lytic converter. Otherwise, there is the
danger of overheating and damage to
the catalytic converter.
Extreme temperatures are present with
the catalytic converter both on this and
every catalytic converter-equipped
vehicle. Heat shields are installed adja-
cent to some sections of the exhaust
system. Never remove these shields;
do not apply undercoating to their
surfaces. When driving, standing at
idle, and parking the vehicle, take care
to avoid contact between the exhaust
system and flammable materials (grass,
hay, leaves etc.). Such contact could
start a fire, resulting in serious personal
injury and property damage.<
