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
>is not active when driving in reverse

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.

Load
The permitted load is the total of the weight of
occupants and cargo/luggage. The greater the
weight of occupants, the less cargo/luggage
can be transported.
Stowing cargo
>Load heavy cargo as far forward and as low
as possible, placing it directly behind the
bulkhead behind the rear seats.
>Cover sharp edges and corners.
Securing cargo
>Use the luggage net* or securing straps to
hold down small and lightweight luggage
and cargo.
>Heavy-duty cargo straps
* for securing
larger and heavier objects are available at
your BMW center. Four lashing eyes
mounted in the luggage compartment are
used to secure these heavy-duty cargo
straps, refer to arrows.
>Please observe the special instructions
supplied with the heavy-duty cargo straps.
Always position and secure the load as
described above, otherwise it may
present a danger to passengers during braking
or evasive maneuvers.
Never exceed either the approved gross vehicle
weight or either of the approved axle loads, refer
to page192, as excessive loads can pose a
safety hazard, and may also place you in viola-
tion of freeway safety laws.
You should never transport heavy or hard
objects unsecured in the passenger compart-
ment, as they could fly around and pose a safety
hazard to the vehicle's occupants during abrupt
braking or evasive maneuver.<
Pad on bottom of luggage
compartment
If required, you can use the pad e.g. to transport
dirty or soiled objects. The rubberized side is
washable and has an anti-slip effect.
