If there is a system malfunction, there is
a risk that the airbags will not be trig-
gered within their normal response
range, even if the level of impact would
normally have triggered them.
Have your BMW center inspect the sys-
tem immediately.
Transporting children safely
Leave the rear safety belts in the
holders if they are not needed to
avoid unwanted movement from the
safety belts at high speeds.<
Commercially available child seats
complying with the legal standard are
designed to be secured with a seat belt
or with the seat belt portion of a combi-
nation lap/shoulder belt. Improperly or
inadequately installed restraint sys-
tems can increase the risk of injury to
children. Always read and follow the
instructions that come with the system.
Child-restraint system with tether
strapIf you use a child-restraint system with
a tether strap, two additional tether
anchorage points have been provided –
refer to the arrows in the illustration.

Depending on the location selected for
seating in the rear passenger area,
attach the tether strap to the corre-
sponding anchorage point to secure the
child-restraint system, as shown in the
illustration.
1. Open the convertible top compart-
ment lid, refer to page41
2. Lift the headrest and pass the tether
strap between the headrest and the
seat back. It is recommended that
you return the head restraint back to
its lowest possible position
3. Adjust the tether strap according to
the child-restraint manufacturer's
instructions
4. Close the convertible top compart-
ment panel.
It is recommended to cover the child-
restraint attaching clip with a soft mate-
rial to prevent damage to the stored
soft top.
Should a hard top be installed, the
fitting of child harness tether
strap/s – if child seat is required – is
necessary before installation of the
hard top.<
Before installing any child-
restraint device or child seat,
please read the following:
Never install a rearward-facing child-
restraint system in the front passenger
seat of this vehicle.
Your vehicle is equipped with an airbag
supplemental restraint system for the
front passenger. Because the backrest
on any rear-facing child-restraint sys-
tem – of the kind designed for infants
under 1 year and 20 lbs/9 kg – would
be within the airbag's deployment
range, you should never mount such a
device in the front passenger seat, as
the impact of the airbag against the
child-restraint's backrest could lead to
serious or fatal injuries.
If it is necessary for a child – not an
infant – to ride in the front seat, certain
precautions should be taken. First,
move the passenger seat as far away
from the instrument panel as possible.
This important precaution is intended to
maximize the distance between the air-
bag and the child. Older children

should be tightly secured with the
safety belt after they have outgrown a
booster seat that is appropriate for their
age, height, and weight.
Younger children should be secured in
an appropriate forward-facing child-
restraint system that has first been
properly secured with a safety belt.
Never install a rearward-facing child-
restraint system in the front passenger
seat.
We strongly urge you to carefully read
and comply with the instructions for
installation and use provided by the
child-restraint's manufacturer whenever
you use such a device.
Do not attempt to modify child-restraint
systems. If you do this, the protection
provided by these systems could be
impaired.
Be sure that all occupants – of all ages –
remain properly and securely restrained
at all times.<
All rear seating positions in your vehicle
meet the recommendations of
SAE J1819, an industry-recommended
practice for securing child-restraint sys-
tems in motor vehicles.
Securing child-restraint systemAll of the rear belt retractors and the
front passenger's safety belt can be
locked for mounting and securing child-
restraint systems.
A label with the appropriate instructions
for this is located in the immediate
vicinity of the buckle latch of each
safety belt.To lock the safety beltExtract the entire length of the belt from
the inertia reel mechanism. Allow the
reel to retract the belt somewhat and
engage the buckle, then tighten the belt
against the child-restraint system. The
retraction mechanism is now locked.
The belt cannot be extracted further.
Always observe the installation instruc-
tions provided by the manufacturer of
the child-restraint system.To unlock the safety belt Release the safety belt, remove the
child seat and retract the safety belt to
its end position on the belt retractor.

Switching off the engine
You should never remove the igni-
tion key when the vehicle is in
motion, as the steering lock could
engage.
When you leave the vehicle, always
remove the ignition key and engage the
steering lock.<
Always engage the parking brake
when parking on downhill roads.
Engaging a gear may not sufficiently
secure the vehicle against rolling.<
Manual transmissionTurn the ignition key to position 1 or 0.Sequential M gearbox SMG IIIf you turn the ignition key to position 1
or 0 with the selector lever in the for-
ward or reverse position, a gear auto-
matically remains engaged.
If you turn the ignition key to position 1
or 0 with the selector lever in position 0,
a warning tone and the flashing gear
indicator in the SMG display remind you
that the vehicle is not secured against
rolling.
The warning stops after approx. ten
seconds. If you move the selector lever
into a forward or reverse position dur-
ing this time, a gear is automatically
engaged.
Parking brakeThe parking brake is designed primarily
to prevent the vehicle from rolling when
it is parked. It operates against the rear
wheels.To engageThe detent engages automatically, and
the indicator lamp in the instrument
cluster comes on when the ignition key
is in position 2, refer to page 18.To releasePull up slightly on the lever, press the
button – see arrow – and lower the
lever.

If exceptional circumstances
make it necessary to engage the
parking brake while the vehicle is in
motion, do not pull it with excessive
pressure. Keep your thumb pressed
against the release button while care-
fully pulling the lever up.
Excessive pressure can lead to over-
braking and loss of traction – fishtailing
– at the rear axle.
The brake lamps do not come on when
the parking brake is engaged.
Always engage the parking brake when
parking on downhill roads. Engaging a
gear may not sufficiently secure the
vehicle against rolling.<
To avoid corrosion and one-sided
braking, apply the parking brake
lightly from time to time when coasting
to a standstill – at a traffic signal, for
example – provided that it is safe to do
so.<
Manual transmission
When shifting gears in the
fifth/sixth gear plane, be sure to
press the gearshift lever to the right in
order to prevent inadvertent selection
of a gear in the third/fourth gear plane.
Do not hold the vehicle in place on
slopes by slipping or "riding" the clutch.
Use the parking brake instead. Riding
the clutch causes the clutch assembly
to wear out sooner.<
ReverseSelect only when the vehicle is station-
ary. Press the shift lever to the left to
overcome the resistance.
As you do this, the backup lamps will
light up automatically when the ignition
key is in position 2.

Shifting gears with shift paddles on
steering wheel:
>To upshift, briefly pull the right pad-
dle +
>To downshift, briefly pull the left pad-
dle –.
Shift paddles with various widths
matched to the shape of your
hand are available from your BMW cen-
ter.<
Shifting gears with selector lever:
>To upshift, pull the selector lever
backward +
>To downshift, push the selector lever
forward toward –.
No automatic upshifting is carried out in
the sequential mode.
You accelerate from higher gears, e.g.
during passing, by manually downshift-
ing.
In the following situations the SMG II
helps you think in the sequential mode:
>Upshifts and downshifts are only exe-
cuted when the new gear will provide
a suitable combination of vehicle and
engine speed, i.e., downshifts that
would cause the engine to overrev
will not be executed
>During a stop the gearbox is auto-
matically downshifted into the first
gear so that, e.g. before a traffic light,
it is only necessary to accelerate to
continue driving
>When the speed is reduced, the
gearbox is automatically down-
shifted shortly before a gear-depen-
dent minimum speed is reached with-
out you taking any action.A – Automated modeEach time the engine is started, the
automated mode is activated as soon
as you move the selector lever into the
forward driving position.
In the automated mode all forward
gears are automatically shifted.Changeover from sequential to auto-
mated mode: tap the selector lever to
the right toward A. Watch the display in
the instrument cluster, refer to page 72.
For rapid acceleration, e.g. during
passing, depress the accelerator pedal
completely – kickdown. The gearbox
now downshifts in dependence on the
selected driving program.
Even in the automated mode, you can
help specify the shifting point: if a gear-
dependent minimum speed is
exceeded, you can upshift by slowly
reducing pressure on the accelerator
pedal. In the process, the respective
driving situation is detected by sensors
and taken into account.

Indicator lamp
The transmission indicator lamp
in the instrument cluster goes
out after the engine is started.
>If it does not go out, or if it lights up
during driving, a fault has occurred.
The available functions may be lim-
ited under certain circumstances.
Drive carefully and with the Dynamic
Stability Control (DSC) activated.
Have the system checked by the
nearest BMW center
>If the indicator lamp flashes while
driving, the system is overloaded.
Avoid high loads until the indicator
lamp goes out again permanently.
Shift lightsTo achieve the best possible vehicle
acceleration with a sporty driving style
in the sequential mode, shift lights in
the instrument cluster indicate the opti-
mum shifting point shortly before the
maximum engine speed is reached.
1. When the maximum engine speed is
approached, yellow indicator fields,
shift lights, in the tachometer light up
consecutively to indicate the
approaching upshift time
2. Shift at the latest when the last indi-
cator field lights up red.
Tire replacement, snow chainsFollowing a tire or wheel change and
after mounting or removing snow
chains, the slip recognition of the
SMG II must become familiar with the
changed condition.
Reinitialize the system afterwards:
1. Move the selector lever into
position 0 on a straight stretch of
road at a speed of over 20 mph /
30 km/h
2. Pull both shift paddles for approx.
two seconds.
If you do not carry out the initialization,
the system automatically learns the
changed condition gradually during
driving. This can become apparent due
to brief opening and closing of the
clutch.

Dynamic Stability Control (DSC)The conceptDSC maintains vehicle stability, even in
critical driving situations.
The system optimizes vehicle stability
during acceleration and when starting
from a full stop, as well as optimizing
traction. In addition, it recognizes
unstable vehicle conditions, such as
understeering or oversteering, and,
within physically feasible limits, helps
keeping the vehicle on a steady course
by reducing the engine speed and
brake applications to the individual
wheels.
The system starts up automatically
each time you start the engine.
The laws of physics cannot be
repealed, even with DSC. The
results of driving irresponsibly rest with
the driver. We therefore urge you to
avoid using the additional safety margin
of the system as an excuse for taking
risks. Do not make any modifications to
the DSC system. Allow only authorized
technicians to perform service proce-
dures on the DSC.
At first, you may need some time to
become accustomed to this system's
intervention. However, it guarantees
optimum drive force and at the same
time, the best possible vehicle stabil-
ity. The indicator lamp in the instru-
ment cluster will go out shortly
after the ignition has been
switched on, refer to page 19.
>Indicator lamp flashes: the system is
active and is controlling the drive
torque based on driving conditions
>If the indicator lamp fails to go out
after the engine has been started, or
if it comes on during normal driving
and stays on: the system has been
deactivated via the button or is
defective. You can continue to drive
the vehicle normally, but without
DSC. Please consult your BMW cen-
ter for repairs.
To deactivate the systemPress the button; the indicator lamp
comes on and stays on.
The vehicle does not execute the stabil-
ity-enhancement and traction-control
functions when DSC is deactivated.
We recommend that you deactivate the
system for increased traction:
>When rocking the vehicle or starting
off in deep snow or on loose surfaces
>When driving with snow chains
>When driving on snow-covered
grades, in deep snow, or on a snow-
covered surface that has been
packed down from being driven on.
To maintain vehicle stability,
always drive with the system
switched on whenever possible.<
