Switching the cooling function on
and off
The cooling function cools and
dehumidifies the incoming air
before reheating it as required,
according to the temperature set-
ting. This function is only available while the
engine is running.
The cooling function helps prevent condensa-
tion on the windows or removes it quickly.
Depending on the weather, the windshield may
fog over briefly when the engine is started.
The cooling function is automatically switched
on along with the AUTO program.
Maximum cooling
Maximum cooling is achieved most
quickly at outside temperatures
above 327/06 and when the
engine is running.
The automatic climate control goes into recir-
culated-air mode at the lowest temperature. Air
flows at maximum rate from the vents for the
upper body area. You should therefore open the
vents for maximum cooling.
AUTO program
The AUTO program automatically adjusts the
air distribution to the windshield and side win-
dows, towards the upper body area, and into the
footwell and knee area.
The air flow rate and air distribution, in addition
to your temperature specifications, will be
adapted to outside influences as a result of sea-
sonal changes, e.g., sunlight or window con-
densation.
The cooling is switched on automatically with
the AUTO program.
Switching on/off
Press the button.
Manual air distribution and air flow rate are acti-
vated when the AUTO program is deactivated.
AUTO program climate level
The climate levels can be used to vary the inten-
sity when the AUTO program is switched on.
For example, air flow is adjusted automatically
to optimize climate control.
When the AUTO program is
switched on, you can select the cli-
mate level of the AUTO program
using the buttons for controlling the manual air
flow rate.
The selected climate level is displayed by
an LED.
Convertible program
When the hardtop is open, the convertible pro-
gram is activated as well. In the convertible pro-
gram, the automatic climate control is opti-
mized for driving with the hardtop open. In
addition, the air flow rate is increased as vehicle
speed increases.
The effectiveness of the convertible pro-
gram can be enhanced considerably by
installing the wind deflector.<
Adjusting air flow rate manually
Press the left side of the button to
reduce air flow. Press the right side
of the button to increase it.
The air flow rate may be reduced to save battery
power. The display remains the same.
Switching the system on/off
With the blower at its lowest setting, press the
left side of the button to switch off the auto-
matic climate control. All displays are cleared
except for the rear window defroster if it is
switched on.
Press any button except the rear window
defroster to reactivate the automatic climate
control.

switch.
The engine can be switched off when the trans-
mission is in position N. Refer also to page209.
Cargo loading
To avoid loading the tires beyond their
approved carrying capacity, never over-
load the vehicle. Overloading can lead to over-
heating and increases the rate at which damage
develops inside the tires. This can ultimately
result in a sudden blowout.<
Make sure that no liquids are spilled or
leak from their containers in the cargo
area, as this could result in damage to the
vehicle.<
Always position and secure the cargo as
described so that it cannot endanger the
car's occupants, for example if sudden braking
or swerving is necessary.
Never exceed either the approved gross vehicle
weight or either of the approved axle loads, refer
to page228, as excessive loads can pose a
safety hazard, and may also place you in viola-
tion of traffic safety laws.
Heavy or hard objects should not be carried
loose inside the car, since they could be thrown
around, for example as a result of heavy braking,
sudden swerves, etc., and endanger the occu-
pants.<
Determining loading limit
1.Locate the following statement on your
vehicle's placard
*:
The combined weight of occupants
and cargo should never exceed
XXX kg or YYY lbs. Otherwise, overloading
can result in damage to the vehicle and
unstable driving conditions.<
2.Determine the combined weight of the
driver and passengers that will be riding in
your vehicle.
3.Subtract the combined weight of the driver
and passengers from XXX kilograms or YYY
pounds.
4.The resulting figure equals the available
amount of cargo and luggage load capacity.
For example, if the YYY amount equals
1,400 lbs and there will be five 150 lbs
passengers in your vehicle, the amount of
available cargo and luggage load capacity
is 650 lbs:
1,400 lbs minus 750 lbs = 650 lbs
5.Determine the combined weight of luggage
and cargo being loaded on the vehicle. That
weight may not safely exceed the available
cargo and luggage load capacity calculated
in step 4.
6.If your vehicle will be towing a trailer, part of
the load from your trailer will be transferred
to your vehicle. Consult the manual for
transporting a trailer to determine how this
may reduce the available cargo and luggage
load capacity of your vehicle.

Things to remember when driving
116
Load
The permissible load is the sum of the occu-
pants' weights and the weight of the cargo. The
greater the weight of the occupants, the less
cargo/luggage can be transported.
Stowing cargo
Cargo area
>Load heavier cargo as far forward as possi-
ble, directly behind the cargo area partition,
and as low as possible.
>Cover sharp edges and corners.
Before opening the hardtop, fold down
the cargo area partition. Make sure the
cargo area is loaded correctly; otherwise,
parts of the hardtop can be damaged, refer
to page38.<
Lateral storage shelf
When storing objects on the lateral stor-
age shelf, do not move both seats all the
way forward while moving them to their upper-
most position and leaning the backrests for-
ward. Otherwise, the seats could hit and dam-
age the seal on the windshield, the sun visor
and the headliner.<
Light and small objects can be stored on the lat-
eral storage shelf.
Securing cargo
Cargo area
Secure smaller and lighter items using retaining
straps, a cargo area net
* or draw straps*.
Lateral storage shelf
You can obtain cargo straps* from your BMW
center. Four lashing eyes are provided behind
the seats for attaching the cargo straps.
Adhere to the information included with the
cargo straps.
