Do not apply adhesive materials to the
cover panels of the airbags, cover them or
modify them in any other way.
Do not attempt to remove the airbag retention
system from the vehicle. Never modify or
tamper with either the wiring or the individual
components in the airbag system. This cate-
gory includes the upholstery in the center of the
steering wheel, on the instrument panel, the
side trim panels on the doors and on the Coupe,
the roof pillars along with the sides of the head-
liner. Do not attempt to remove or dismantle the
steering wheel.
Do not touch the individual components
directly after the system has been triggered,
because there is a danger of burns.
If you note any indication of system malfunc-
tion, if you wish to have an airbag deactivated,
or if the airbag retention system is triggered in
response to an accident, you should always
entrust all inspection, repair and dismantling
operations to your BMW center. Unprofessional
attempts to service the system could lead to
failure in an emergency or undesired airbag
activation, either of which could result in per-
sonal injury.<
Airbag warning information is also provided on
the sun visors.
Operational readiness of airbag system
From ignition key position 1 the warning lamp
lights up briefly, indicating the operational
readiness of the entire airbag system and the
belt tensioners.
Airbag system malfunction
>The warning lamp does not light up as of
ignition key position 1.>The warning lamp lights up continuously.
Have the airbag system checked immedi-
ately if a malfunction occurs, as otherwise
there is a danger of the system not responding
in the expected manner to an impact occurring
within its normal response range.<
Convertible:
Rollover protection system
The rollover protection system is automatically
activated in the event of an accident or a critical
driving situation, extreme inclination on the lon-
gitudinal or transverse axis, or loss of ground
contact. The rollover bars located behind the
rear head restraints are deployed within frac-
tions of a second.
As a supplement to the rollover bar integrated
into the windshield frame, the rollover protec-
tion system ensures that all vehicle occupants
have the necessary headroom.
Always keep the path of movement of the
rollover protection system clear.
In less severe accidents, you are protected by
the fastened safety belt and, depending on the
severity of the accident, the belt tensioner and
the multistage airbag restraint system.<
Lowering
If the protection function was not required after
automatic activation, the rollover protection
system can be lowered again. No tools are nec-
essary for this purpose.
1.Press the release backward and hold in that
position.

Lamps
92 The low beams remain on independent of
the ambient lighting conditions when you
switch on the fog lamps.
With the daytime driving lamps activated, the
low beams are always switched on in this switch
position with the ignition key in position 2.<
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. To avoid safety risks, you
should always switch on the lamps manually
under these conditions.<
Adaptive Head Light*
The concept
Adaptive Head Light is a variable headlamp
control system that enables better illumination
of the road surface. Depending on the steering
angle and other assumptions, the light from the
headlamp follows the course of the road.
Activating Adaptive Head Light
In switch position3 the Adaptive Head Light is
active and the automatic headlamp control is
switched on.
To avoid blinding oncoming traffic, the Adaptive
Head Light

You also enjoy the option of lighting up just one
side of your vehicle when parking. When using
this function, comply with national regulations:
With the ignition switched off, press the lever in
the desired direction3, past the resistance
point.
The roadside parking lamps drain the bat-
tery. Avoid using for longer periods, as
otherwise it may not be possible to start the
engine.<
Fog lamps
The parking lamps or low beams must
be switched on for the fog lamps to
operate. The green indicator lamp in
the instrument cluster lights up when the fog
lamps are switched on.

The current setting for air distribution is dis-
played on the Control Display.
A congenial climate
For almost all conditions, the AUTO program
offers the optimal air distribution and air vol-
ume. Select an interior temperature you find
pleasant.
The following section contains more detailed
information on the available setting options.
AUTO program
The AUTO program handles the
adjustment of air distribution to the
windshield and side windows, in
the direction of the upper body, and in the foot-
well, as well as the adjustment of the air volume.
It also adapts your instructions for the tempera-
ture to outside influences throughout the year.
The cooling is switched on automatically with
the AUTO program. At the same time, a con-
densation sensor controls the program in such
a way that window condensation is prevented
as much as possible.
Temperature adjustment
By rotating, you can set a desired
temperature for the driver's side
and the passenger side.
After you start to drive, this system
ensures that the selected temperature is
achieved as quickly as possible. It then main-
tains this temperature, regardless of the sea-
son.
Defrosting windows and removing
condensation
This program quickly removes ice
and condensation from the wind-
shield and front side windows.
Air volume, manual
You can adjust the air volume by
turning. You can reactivate the
automatic mode for the air volume
with the AUTO button.
Switching cooling function on and off
manually
The cooling function cools and
dehumidifies the incoming air
before reheating it as needed
according to the temperature setting. Depend-
ing on the weather, the windshield may fog over
briefly when the engine is started.
The air conditioner can operate only when the
engine is running. The AUTO program auto-
matically switches on the air conditioner.
Maximum cooling
This program quickly provides
maximum cooling.
The system switches to the recir-
culated-air mode and the air flows
at maximum air volume only from the vent out-
lets for the upper body area. For this reason you
should ensure that these vent outlets are open
before selecting this program.
AUC automatic recirculated-air
control/recirculated air mode
You can respond to unpleasant
odors or pollutants in the immedi-
ate environment by temporarily
suspending the supply of outside air. The sys-
tem then recirculates the air currently within the
vehicle. In AUC mode, a sensor detects pollut-
ants in the outside air and controls the shut-off
automatically.
Press the button repeatedly to run through the
following control sequence:
>LED off: outside air flows into the vehicle
continuously.
>Right LED on, AUC mode: the system
detects pollutants in the outside air and
responds by blocking the supply of outside
air when required.
>Left LED on, recirculated-air mode: the
supply of outside air into the vehicle is shut
off continuously.
If condensation starts to form on the
inside window surfaces during operation
in the recirculated-air mode, you should switch

Integrated universal remote
control*
The concept
The integrated universal remote control
replaces up to three different hand-held trans-
mitters for various items of radio-controlled
equipment such as door openers and house
alarm systems. The integrated universal remote
control registers and stores signals from the
original hand-held transmitters.
The signal of an original hand-held transmitter
can be programmed into one of the three mem-
ory buttons1. Then the respective device can
be actuated using the memory button1 pro-
grammed for its use when the ignition key is in
position 2. The LED2 flashes to confirm trans-
mission of the signal.
If you sell your vehicle one day, delete the saved
programs beforehand for your own security,
refer to page101.
To prevent possible damage or injury,
before programming or using the inte-
grated universal remote control, always inspect
the immediate area to make certain that no peo-
ple, animals or objects are within the travel
range of the device. Also comply with the safety
precautions of the original hand-held transmit-
ter.<
Checking compatibility
If you see this symbol on the packaging
or in the manual supplied with the orig-
inal hand-held transmitter, it is safe to
assume that it is compatible with the integrated
universal remote control.
If you have additional questions, please consult
your BMW center or call 1-800-355-3515.

You can operate the system when the ignition
key is in position 2.
If the device cannot be used after
repeated programming, check whether
the original hand-held transmitter uses an alter-
nating-code system. To do so, either read the
instructions for the original hand-held transmit-
ter or press the programmed memory button1
of the integrated universal remote control
longer. If the LED 2 on the integrated universal
remote control flashes rapidly for a short time
then lights up for approx. 2 seconds, this indi-
cates that the original hand-held transmitter
uses an alternating-code system. In the case of
an alternating-code system, program the mem-
ory buttons1 as described at Alternating-code
hand-held transmitters.<
Alternating-code hand-held
transmitters
To program the integrated universal remote
control, consult the operating instructions for
the equipment to be set. You will find informa-
tion there on the possibilities for synchroniza-
tion.
When programming hand-held transmitters
that employ an alternating code, please observe
the following supplementary instructions:

Mobile communication devices in
vehicle
BMW advises against using mobile com-
munication devices, e.g. portable phones,
inside the vehicle without a direct connection to
an external antenna. Otherwise, the vehicle
electronics and mobile communication device
can influence one another. In addition, there is
no assurance that the radiation emitted during
transmission will be conveyed out of the vehicle
interior.<
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 phenomenon is referred to as hydro-
planing, and is characterized by a partial or
complete loss of contact between the tires and
the road surface, ultimately undermining your
ability to steer and brake the vehicle.<
The risk of hydroplaning increases as the tread
depth of the tires decreases, also refer to Mini-
mum tire tread on page171.
Driving through water
Do not drive through water on the road if it
is deeper than 1 ft/30 cm, and then only at
walking speed at the most. Otherwise, the vehi-
cle's engine, the electrical systems and the
transmission may be damaged.<
Using handbrake on inclines.
On inclines, do not hold the vehicle with
the clutch; use the handbrake. Otherwise
greater clutch wear will result.<
SMG Sequential manual transmission
Start off quickly on slopes. Do not hold
the vehicle on a hill by applying the throt-
tle, but engage the handbrake instead. Other-
wise overheating can occur in the transmission
region.<
Braking safely
Your BMW is equipped with ABS as standard. In
situations that require it, it is best to brake with
full force. 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.
Do not drive with your foot resting on the
brake pedal. Even light but consistent
pedal pressure can lead to high temperatures,
brake wear and possibly even brake failure.<
Driving in wet conditions
When driving on wet roads or in heavy rain,
briefly brake with light pedal pressure at inter-
vals of a few miles. Monitor traffic conditions to
ensure that this maneuver does not endanger
other road users. The heat generated in this
process helps dry the pads and rotors to ensure
that full braking efficiency will then be available
when you need it.
Hills
To prevent overheating and thus reduced
efficiency of the brake system, downshift
to a gear in which only minimal brake applica-
tions are needed when descending long or
steep downhill stretches. Even light but consis-
tent pedal pressure can lead to high tempera-
tures, brake wear and possibly even brake fail-
ure.<
You can further enhance the engine's braking
effect by selecting a lower gear in the automatic
transmission's manual mode, downshifting as
far as first gear on extremely steep stretches,
refer to page58. This strategy helps you avoid
placing excessive loads on the brake system.
Never drive with the clutch pressed
or allow the vehicle to coast with the
transmission in Neutral – or with the engine
switched off – there is no engine braking when
the transmission is in Neutral, and no power
assist for brakes and steering when the engine
is not running.

Things to remember when driving
110 Never allow floor mats, carpets or any other
objects to protrude into the area around the
accelerator and brake pedals and obstruct their
movement.<
Corrosion on brake rotors
When the vehicle is driven only occasionally,
during extended periods when the vehicle is not
used at all, and in operating conditions where
brake applications are less frequent, there is an
increased tendency for corrosion to form on
rotors, while contaminants accumulate on the
brake pads. This occurs because the minimum
pressure which must be exerted by the pads
during brake applications to clean the rotors is
not reached.
Should corrosion form on the brake rotors, the
brakes will tend to respond with a pulsating
effect that even extended application will fail to
cure.
When the vehicle is parked
Condensation forms in the automatic air condi-
tioner system during operation, and then exits
under the vehicle. Traces of condensed water
under the vehicle are therefore normal.
Before driving into a car wash
To prevent the exterior mirrors from being
damaged due to the width of the vehicle,
always fold them in by hand before entering an
automatic car wash.<
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. The ultimate result
can assume the form of a sudden blow-out.<
Determining loading limit
1.Locate the following statement on your
vehicle's placard
*:
The combined weight of occupants
and cargo should never exceed
XXX lbs. or YYY kg, as otherwise the vehicle
may be damaged and unstable driving con-
ditions may result.<
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 lbs. or YYY kg.
4.The resulting figure equals the available
amount of cargo and luggage load capacity.
For example, if the XXX amount equals
800 lbs. and there will be four 150-lbs. pas-
sengers in your vehicle, the amount of avail-
able cargo and luggage load capacity is
200 lbs.:
800 lbs. minus 600 lbs. = 200 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.
