activation system.
Requirements
The same prerequisites apply as for operation
via iDrive, refer to page177.
Saying commands
Activating voice activation system
1.Briefly press the button on the steering
wheel.
A sound signal indicates that you can say
commands.
2.Say the command.
Ending/canceling operation by voice
commands
Briefly press the button on the steering
wheel orIn dialogs not involving voice commands, i.e.
when you are speaking only text, e.g. a name,
canceling is possible only via the button on the
steering wheel.
Having the possible commands read
aloud
The system recognizes specific commands
that must be pronounced exactly word for word.
You can have the possible commands for any
function read aloud to you:
Digits from zero to nine are recognized.
You can say each digit individually or group
them into a sequence to accelerate the input.
Using alternative commands
Often there is more than a single command to
run a function, e.g.:
Example: dialing phone numbers
To start the dialog:
Press the button on the steering wheel.
Adjusting the volume of the
instructions
You can adjust the volume for the instructions
from the system:Turn the button during an instruction.
This volume for the instructions is maintained,
even if the other audio sources are set to mini-
mum volume.
The setting is stored for the remote control cur-
rently in use. {Cancel}.
{Help}.
{Dial name} or {Name}.

e.g. {123 456 7890}Depending on your equipment version:
{{123 456 7890. Continue ?}}

Tire inflation pressures
Information for your safety
It is not merely the tires' service life, but also
driving comfort and, to a great extent, driving
safety that depend on the condition of the tires
and the maintenance of the specified tire pres-
sure.
Check the tire inflation pressure regularly
and correct it, if necessary: at least twice a
month and before starting long trips. If you fail
to observe this precaution you may be driving
on tires with incorrect tire pressures, a condi-
tion that can not only compromise your vehi-
cle's driving stability, but also lead to tire dam-
age and the risk of an accident. Do not drive
with deflated, i.e. flat tires, except when using
run-flat tires. A flat tire will seriously impair your
vehicle's handling and braking response.
Attempts to drive on a flat tire can lead to loss of
control over the vehicle.<
Checking pressure
Only check tire inflation pressure when the
tires are cold. This means after a maximum of
1.25 miles/2 km driving or when the vehicle has
been parked for at least 2 hours. When tires are
warm, the tire inflation pressure is higher.
After correcting the tire inflation pressure,
reset the Tire Pressure Monitor, refer to
page86, or reinitialize the Flat Tire Monitor,
refer to page85.<
Inflation pressure specifications
The tables below provide all the correct inflation
pressures for the specified tire sizes at ambient
temperature.
The inflation pressures apply to the tire
sizes approved and tire brands recom-
mended by BMW; a list of these is available
from your BMW center.<
For correct identification of the right tire infla-
tion pressures, observe the following:>Tire sizes for your vehicle
>Load conditions
>Maximum allowable driving speed
Tire inflation pressures for driving up to
100 mph or 160 km/h
For normal driving up to 100 mph or 160 km/h
and to achieve optimum driving comfort, adjust
pressures to the respective tire inflation pres-
sures listed on the following pages in the col-
umns for traveling speeds up to a maximum of
100 mph or 160 km/h.
These tire inflation pressures can also be found
on the driver's side door post when the driver's
door is open.
The maximum permissible speed for
these tire pressures is 100 mph or
160 km/h. Do not exceed this speed; otherwise,
tire damage and accidents could occur.<
Tire inflation pressures for driving
above 100 mph or 160 km/h
In order to drive at maximum speeds in
excess of 100 mph or 160 km/h, adjust
pressures to the respective tire inflation pres-
sures listed on the following pages in the col-
umns for traveling speeds including those
exceeding 100 mph or 160 km/h. Otherwise,
tire damage and accidents could occur.<
Observe all national and local maximum speed
limits; otherwise, violations of the laws could
occur.
