recommended for a performance-oriented driv-
ing style. It is engaged automatically when the
Dynamic Driving Control is activated, see
below.
When the selector lever is briefly moved for-
ward or back, the manual mode is activated and
the Steptronic shifts gear. The instrument clus-
ter shows M1 through M6.
Upshifts and downshifts are executed only
when they will result in a plausible combination
of engine and vehicle speed; thus, for example,
a downshift that would cause the engine to
overrev will not be executed by the system. The
selected gear appears briefly in the instrument
cluster, followed by the current gear.
To use the automatic function again, move the
selector lever to the right into position D.
Dynamic Driving Control
The Dynamic Driving Control makes it possible
for your BMW to react in an even more perfor-
mance-oriented manner at the push of a button:
>The engine responds more spontaneously
to accelerator pedal movements.
>Cruise control:
The stored speed is reached more quickly
when it is requested.
Additionally with SMG:
>Gearshifts are faster.
>The engine speed range is used optimally in
the Drive mode.
With automatic transmission:
>The Sport program is activated.
Activating system
In ignition key position 2, press the SPORT but-
ton.
The LED in the button lights up and SPORT is
displayed in the instrument cluster.
Deactivating system
>Press the SPORT button again or
>engage reverse gear or
>switch off the engine.
The LED in the button and SPORT in the instru-
ment cluster go out.
Acceleration assistant with SMG
The acceleration assistant enables optimized
vehicle acceleration at racing car level on road
surfaces with good adhesion when starting off.
Do not use the acceleration assistant too
often, as otherwise components will wear
prematurely.<

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.

1.Ignition key in position 2.
2.When using for the first time: press both
outer buttons 1 for approx. 20 seconds,
maintaining pressure until the LED 2 starts
to flash. The three memory buttons1 are
cleared.
3.Hold the original hand-held transmitter at a
distance of approx. 2 in/5 cm to 8 in/20 cm
to the memory buttons1.
The required distance between the
hand-held transmitter and the mem-
ory buttons1 depends on the respective
system of the original hand-held transmitter
used.<
4.Simultaneously press the transmit button
on the original hand-held transmitter and
the desired memory button1 on the inte-
grated universal remote control. Initially, the
LED2 flashes slowly. Release both buttons
as soon as the LED 2 flashes rapidly. If the
LED2 does not flash rapidly after approx.
15 seconds, change the distance.
5.To program other original hand-held trans-
mitters, repeat steps 3 and 4.
The corresponding memory button1 is now
programmed with the signal of the original
hand-held transmitter.

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.

Under the hood

Under the hood
Never attempt to perform any service or
repair operations on your vehicle without
the required, professional technical training. If
you are unfamiliar with the specifications to be
observed, only have work carried out on your
vehicle by a BMW center or a workshop which
works with personnel trained in accordance
with BMW specifications. Otherwise there is a
danger of damage and associated safety risks if
this work is performed improperly.<

40 cm with momentum. It must be clearly heard
to engage.
Make sure that the closing path of the
hood is clear, as otherwise injuries may
result.
If you see any signs that the hood is not com-
pletely closed while you are driving your vehicle,
you should stop at once and close it securely.<

LEDs Light-emitting diodes
Light-emitting diodes installed behind translu-
cent lenses serve as the light source for many of
the controls and displays in your vehicle. These
light-emitting diodes, which operate using a
concept similar to that applied in conventional
lasers, are officially designated as Class 1 light-
emitting diodes.
Do not remove the covers, and never
stare into the unfiltered light several
hours, as irritation of the retina could result.<
Changing a wheel
Your BMW is equipped with run-flat tires as
standard. An immediate wheel change in the
event of a flat tire is therefore no longer
required.
You will recognize run-flat tires by a circular
symbol containing the letters RSC on the side
of the tire, refer to Run-flat tires on page171.
If you have new tires mounted or switch from
summer to winter tires, or vice versa, use run-
flat tires, as in the event of a flat tire there is no
spare tire available. Your BMW center will be
glad to advise you.
Also refer to New wheels and tires, page172.
Car jacking points
The jacking points for the car jack are located in
the positions shown.
The suitable tools for changing tires are
available as accessories from your BMW
center.<
Vehicle battery
Battery care
The battery is 100 % maintenance-free, i.e., the
electrolyte will last for the life of the battery
when the vehicle is operated in a temperate cli-
mate.
Your BMW center will be glad to advise in all
matters concerning the battery.
Charging battery
Only charge the battery in the vehicle via the
terminals in the engine compartment with the
engine switched off. For the connections, refer
to Jump starting on page186.
Disposal
After replacement, have old batteries dis-
posed of by your BMW center or deposit
them at a recycling center. Maintain the battery
in an upright position for transport and storage.
Always secure the battery to prevent it from tip-
ping over during transport.<
