Operation by voice control*
The concept
You can operate your portable phone with-
out having to remove your hands from the
steering wheel. The system operates on
the basis of voice commands that you learn
easily after using them a few times. In addi-
tion, you are also supported by instructions
or questions.
Symbols usedVoice commands
In ignition key position 2:
1.Briefly press the button on the steer-
ing wheel.
A sound signal indicates operating
readiness
2.Speak voice commands.
To have the system list the voice com-
mands possible in each case:
Canceling operation via voice
control
Briefly press the button on the steering
wheel
or
In dialogs where text of any kind can be
spoken, e.g. a name, canceling is only pos-
sible using the button. Voice control dia-
log is automatically interrupted when an
incoming call is received.
Voice commands
In addition to the commands described in
this Owner's Manual, alternative com-
mands are often possible for the same
functions, e.g.:
Digits from zero to nine are understood.
You can say each digit individually or group
them into a sequence of three to five digits
to speed up the process.
{...} Identifies voice commands.
{{...}} Identifies instructions generated
by the system.
{Help}.
{Cancel}.
{Dial name} or {Name}.

Telephoning

An example: dialing a phone number
Start the dialog:
Briefly press the button on the steering
wheel.
Volume adjustment
You can adjust the volume for the instruc-
tions from the system:
Turn the button during an instruction to
select the desired volume.
This volume for the instructions is main-
tained, even if the other audio sources are
set to minimum volume.
Depending on which key you have used to
open the vehicle, the last adjustment is
applied.
First steps

Wheels and tires
168
Run-flat tires
You will recognize run-flat tires by a circular
symbol containing the letters RSC on the
side of the tire.
Run-flat tires consist of self-contained tires
and special rims. The tire reinforcement
ensures that the tire retains some residual
safety in the event of pressure drop and
driving remains possible to a restricted
degree.
Continuing driving with a damaged
tire
Driving on run-flat tires with tire damage
can continue, depending on the vehicle
load and the severity of the tire damage, at
a maximum speed of 50 mph/80 km/h.
You can estimate the possible mileage for
continued driving on the basis of the fol-
lowing general indications:
>With low load:
1 to 2 persons without luggage:
Approx. 155 miles/250 km
>With medium load:
2 persons, luggage compartment full, or
4 persons without luggage:
Approx. 94 miles/150 km
>With full load:
4 persons, luggage compartment full:
Approx. 30 miles/50 km.
Drive reservedly and do not exceed
a speed of 50 mph/80 km/h. In the
event of pressure loss, vehicle handling
changes. This includes reduced track sta-
bility in braking, extended braking distance
and altered natural steering characteristics.
If unusual vibrations occur while the vehicle
is being driven, this can indicate final failure of the damaged tire. Reduce speed and
stop as soon as possible. Do not continue
driving. Contact your BMW center.<
New wheels and tires
You can find out the right wheel-tire combi-
nation from your BMW center. It is another
vital factor in ensuring reliable operation of
various vehicle systems such as ABS and
DSC. Have the wheel and tire assemblies
balanced every time either a wheel or a tire
is replaced.
Only have new wheels and tires
mounted by a specialist. If this work is
performed inexpertly, there is a danger of
damage and associated safety risks.<
Retreaded tires
BMW does not recommend the use of
retread tires, as otherwise driving
safety may be reduced. Possible variations
in the design and the age – which could be
substantial – of the carcasses can lead to
unusually rapid wear.<
The right wheels and tires
BMW recommends that you use only
wheel and tire combinations that
BMW has tested and approved for your
particular vehicle. Variations in factors such
as manufacturing tolerances mean that
even wheels and tires with identical official
size ratings could actually have different
dimensions than the approved units – these
differences could lead to body contact, and
with it the risk of severe accidents. If non-
approved wheels and tires are used, BMW
cannot evaluate their suitability, and there-
fore cannot be held liable for driving
safety.<
To maintain good handling and vehicle
response, use only tires of a single tread
configuration from a single manufacturer.
After a flat tire, always remember to have
the specified wheel and tire combination
remounted on the vehicle as soon as pos-
sible.
