Parking lamps
In switch position1, the front, rear and side
vehicle lighting is switched on. You can use the
parking lamps to signal the position of the vehi-
cle when it is parked. For the additional option
of roadside parking lamps on one side of the
vehicle only, refer to page56.
The parking lamps will discharge the bat-
tery. Therefore, do not leave them on for
unduly long periods of time, otherwise the bat-
tery might not have enough power to start the
engine.<
Low beams
The low beams light up when the light switch is
in position 2 and the ignition is on.
When you switch off the ignition with the low
beam headlamps on, only the parking lamps will
remain on.
Defective bulb
The indicator lamp lights up:
At least one bulb of the vehicle's exte-
rior lighting has failed.
For replacing bulbs refer to page93.
Automatic headlamp control*
When the switch is in position3, the low beams
are switched on and off automatically depend-
ing on ambient light conditions, e.g. in a tunnel,
in twilight, or if there is precipitation.
When driving into tunnels with bright overhead
lights, there may be a delay before the head-
lamps come on.
The headlamps may also come on when the
sun is sitting low on a blue sky.
The low beams remain switched on inde-
pendent of the ambient lighting condi-
tions when you switch on the fog lamps
*.
When daytime running light is activated, refer to
page55, the low-beam headlamps are always
switched on when the switch is in position 3 and
the ignition is on.<
If desired, the light switch can remain in
position3. The exterior lamps are automatically
switched off after the vehicle is parked.
The automatic headlamp control cannot
serve as a substitute for your personal
judgment in determining when the lamps
should be switched on in response to ambient
lighting conditions. For example, the system
cannot detect fog or hazy weather. To avoid
safety risks, you should always switch on the
lamps manually under these conditions.<
You can have the sensitivity of your vehi-
cle's automatic headlamp control
adjusted.<
Daytime running light*
If desired, the light switch can remain in the
automatic headlamp control position. The exte-
rior lamps are automatically switched off after
the vehicle is parked.
In the Parking lamps position, the parking lamps
come on after the ignition is switched off.
If necessary, switch on the parking lamps as
described in the section about parking lamps.

Lamps
56 You can have daytime running light acti-
vated/deactivated on your vehicle.<
Pathway lighting
If you activate the headlamp flasher after park-
ing the car, with the lights switched off, the low
beams come on and remain on for a certain
time.
You can have this function activated/
deactivated as well as the duration of the
pathway lighting set.<
LIGHTS ON warning
Whenever you open the driver's door after hav-
ing turned the key to position 0, you will hear an
acoustic signal for a few seconds to remind you
that the lamps have not been switched off.

Climate
62
Comfortable interior climate
AUTO program 6 offers the ideal air distribution
and air flow rate for almost all conditions, refer
to AUTO program below. In addition, you can
select an interior temperature you find pleasant.
The following sections inform you in detail
about how to adjust the settings.
Air distribution, manual
Direct the flow of air to the windows
, to the upper body area and to
the footwell . Intermediate settings
are possible. The arrow lights up.
The automatic air supply remains unchanged.
You can switch the automatic air distribution
back on by pressing the AUTO button.
Defrosting windows and removing
condensation
Quickly removes ice and condensa-
tion from the windshield and side
windows.
AUTO program
The AUTO program adjusts the air
distribution to the windshield and
side windows, towards the upper
body area and into the footwell for
you. The air flow rate and your temperature
specifications will be adapted to outside influ-
ences as a result of seasonal changes, e.g. sun-
light or window condensation.
The cooling is switched on automatically with
the AUTO program.
The AUTO program functions only to a
limited extent when the convertible top is
open.<
Air flow rate, manual
Adjust the air flow rate. The arrow
lights up.
The automatic air distribution
remains unchanged. You can reactivate the
automatic mode for the air flow rate with the
AUTO button.The higher the air flow rate, the more effective
the air conditioning will be.
Switching the system on/off
Turn the rotary switch to 0. The automatic cli-
mate control is switched off and the air supply is
cut off.
To switch on the automatic climate control, set
any desired air flow rate.
Switching cooling function on/off
When the cooling function is on, the
air is cooled, dehumidified, then
reheated depending on the tempera-
ture setting.
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. The passen-
ger compartment can only be cooled while the
engine is running.
Maximum cooling
At outside temperatures above
327/06 and when the engine is
running, you obtain a maximum cool-
ing effect as soon as possible.
The automatic climate control switches to the
lowest temperature and operates in recircu-
lated-air mode. Air flows at maximum rate only
from the vents for the upper body area. You
should therefore open them for maximum cool-
ing.
Temperature
Set the desired temperature.
The values on the dial are approxima-
tions of the respective temperature
resulting in the passenger compartment.
The automatic climate control achieves this
temperature as quickly as possible regardless
of the season, using maximum cooling or heat-
ing power if necessary, and then maintains it.
If you switch between different tempera-
ture settings in quick succession, the

cannot be ruled out that vehicle electronics and
the mobile communications device interfere
with one another. In addition, it is not ensured
that the radio waves emitted during transmis-
sion are directed outside of the vehicle inte-
rior.<
Interior and exterior mirrors with
automatic dimming feature*
The automatic dimming feature of the interior
and exterior mirrors
* is controlled by two photo
cells in the interior rearview mirror. In the Road-
ster, one is located in the mirror glass, see
arrow. In the Coupe, it is located at the bottom
of the mirror frame. The other photo cell is on
the back of the mirror.
In order to ensure that the system functions
correctly, keep the photocells clean, do not
cover the area between the interior rearview
mirror and windshield, and do not affix adhesive
labels or stickers of any kind to the windshield
directly in front of the mirror.
Hydroplaning
When driving on wet or slushy roads,
reduce vehicle speed. If you do not, a
wedge of water may form between the tires and
the road surface. This situation, known as
hydroplaning, means that the tire can com-
pletely lose contact with the road surface, so
that neither the car can be steered nor the brake
be properly applied.<
The risk of hydroplaning increases with declin-
ing tread depth on the tires, refer also to Mini-
mum tread depth on page83.
Driving through water
Drive through water on the road only if it is
not deeper than 1 ft/30 cm, and then only
at walking speed at the most. Otherwise, the
vehicle's engine, the electrical systems and the
transmission may be damaged.<
Moisture inside the vehicle
Make sure that the passenger compart-
ment does not become wet and that liq-
uids are transported in closed containers.
Otherwise, moisture could penetrate and dam-
age electronic components inside the vehicle.<
Use the parking brake on inclines
On inclines, keep the vehicle from rolling
by using the parking brake rather than by
slipping the clutch, which would lead to a high
degree of clutch wear.<
Braking safely
Your BMW is equipped with ABS as a standard
feature. Applying the brakes fully is the most
effective way of braking in situations in which
this is necessary. Since the vehicle maintains
steering responsiveness, you can still avoid
possible obstacles with a minimum of steering
effort.
Pulsation at the brake pedal combines with
sounds from the hydraulic circuits to indicate to
the driver that ABS is in its active mode.
Wet roads
When roads are wet or there is heavy rain,
briefly exert gentle pressure on the brake pedal
every few miles. Watch traffic conditions to
ensure that this maneuver does not endanger
other road users. The resulting heat dries the
brake rotors and brake pads. Immediate braking
force is then available if necessary.
Inclines
To prevent overheating and, as a result,
diminished braking effectiveness, drive
down long or steep downhill grades in the gear
that requires the least braking. Otherwise, even
light but consistent pedal pressure can lead to

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 can be transported.
Stowing cargo
>Load heavy cargo as far forward as possi-
ble, directly behind the cargo bay partition,
and as low as possible.
>Cover sharp edges and corners.
To avoid damaging the rear of the back-
rests or the rear interior trim panel, do not
stow heavy cargo or cargo with sharp edges
and corners behind the seats.
In addition, large and bulky cargo stowed
behind a seat may prevent the backrest from
engaging properly. Therefore, check the back-
rest to see if it is properly engaged, and move
the seat forward if necessary; refer to page31.
Always position and secure the load as
described above. If you do not, it can endanger
the occupants during braking or evasive
maneuvers.
Never exceed either the approved gross vehicle
weight or either of the approved axle loads, refer
to page109, 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.<
Roadster: convertible top
compartment
The cargo bay can be enlarged when the
convertible top is closed, refer to page23.

vertible top compartment panel down as soon
as you have taken your cargo out of the cargo
bay. This way, you can be sure that you can
always operate the convertible top at any time.
When the convertible top is closed, fold the
convertible top compartment panel up before
stowing your cargo in the cargo bay, to avoid
any damage to the convertible top compart-
ment or your load.
Do not stow any items on the convertible top
compartment panel, otherwise the convertible
top could be damaged while it is opening.<
If you stow cargo behind the seats of your
BMW:
>Only stow light objects such as clothing,
etc.
>Do not pile objects higher than the top edge
of the backrests.
Roadster: hardtop
preparation*
Pull covers off, see arrow1.
The brackets for attaching the hardtop
are located underneath the covers; see arrow2.
