2006 BMW 745i wheel

Technology for comfort, convenience and safety
90 There are two programs.
With each press of the controller, you can
switch back and forth between "Comfort" and
"Sport".
Comfort program
The Comfort program is suitable for use
throughout the vehicle's entire speed range and
regardless of load.
Sport program
You should select the Sport program for consis-
tently performance-oriented response from
shock absorbers and steering.
FTM Flat Tire Monitor*
The concept
The Flat Tire Monitor keeps track of the infla-
tion pressures in the four mounted tires as you
drive. The system triggers an alert whenever
the inflation pressure drops significantly in rela-
tion to the pressure in another tire.
When a loss of pressure occurs, the rolling
radius changes and with it, the rotational speed
of the wheels. This change is detected and sig-
naled as a flat tire.
Functional requirements
To ensure the reliable signaling of a flat tire, the
system must be initialized at the correct tire
inflation pressure.
The initialization must be repeated after
every correction of the tire inflation pres-
sure and after every tire or wheel change.<
System limits
The Flat Tire Monitor cannot indicate
sudden severe tire damage caused by
outside factors and does not detect a natural,
even pressure drop in all four tires.<
In the following situations, the system could be
delayed or malfunction:
>When the system has not been initialized.>When driving on snow-covered or slippery
road surfaces.
>Sporty driving style: slip in the drive wheels,
high lateral acceleration.
>When driving with snow chains
*.
Initializing system
The initialization is completed during driv-
ing, which can be interrupted at any time.
The initialization automatically continues when
driving resumes. Do not initialize the system
when driving with snow chains
*.<
iDrive, for principle details, refer to page16.
1.Select "Settings".
2.Select "Vehicle" and press the controller.
3.Select "FTM" and press the controller.
The initialization menu appears.
4.Start the engine, but do not begin to drive.
5.Select "SET" and press the controller.
During the initialization, "Initialization is run-
ning and will be completed after driving for a
while! Status: FTM is being initialized"
appears on the Control Display.
6.Start driving.
It takes at least 10 minutes before the Flat
Tire Monitor can detect and report a flat tire.
The initialization is completed during driving.
Then the message "Only set after tire pressure
is correctly adjusted (vehicle must be stopped
and ignition on) Status: active" appears on the
Control Display again.
To exit the menu:
Select the arrow and press the controller.

Indication of a flat tire
The warning lamp lights up red and a
message is shown on the Info Display.
In addition, a signal sounds. A flat tire or
a major air loss has occurred.
1.Reduce speed and stop the vehicle care-
fully. Avoid sudden braking and steering
maneuvers.
2.Identify the damaged tire.
If identification is not possible, con-
tact your BMW center.<
3.Replace the damaged tire, refer to Chang-
ing wheels on page209.
Run-flat tires*
1.Cautiously reduce the vehicle speed to
below 50 mph/80 km/h. Avoid sudden brak-
ing and steering maneuvers. Do not exceed
a vehicle speed of 50 mph/80 km/h.
If the vehicle is not equipped with run-
flat tires, refer to page199, do not
continue to drive. Continued driving after a
flat tire can result in serious accidents.<
2.Check the air pressure in all four tires at the
next opportunity.
If the tire inflation pressure in all four
tires is correct, the Flat Tire Monitor
may not have been initialized. The system
must then be initialized.<
3.In the event of a total loss of inflation pres-
sure, 0 psi/kPa, or obvious tire damage, you
can estimate the possible distance for con-
tinued driving on the basis of the following
guide values:
>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. 95 miles/150 km.
>With full load:
More than 4 persons, luggage compart-
ment 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 tracking stability in braking,
extended braking distances, and altered natural
steering characteristics.
If unusual vibrations or loud noises occur while
the vehicle is being driven, this can indicate final
failure of the damaged tire. Reduce speed and
stop at a suitable location as soon as possible;
otherwise, pieces of the tire could come off and
cause an accident. Do not continue driving,
contact your BMW center.<
Malfunction
The warning lamp lights up yellow and
a message is shown on the Info Display.
The Flat Tire Monitor has failed. Have
the system checked as soon as possible.
TPM Tire Pressure Monitor*
The concept
TPM checks the tire inflation pressure in the
four mounted tires. The system indicates if the
tire inflation pressure has dropped considerably
in one or several tires.
Functional requirement
In order to assure the reliable reporting of a flat
tire, the system must have been reset with the
correct tire inflation pressure.
Always use wheels with TPM electronics; oth-
erwise, fault-free operation of the system is not
ensured.
Reset the system again after each correc-
tion of the tire inflation pressure and after
every tire or wheel change.<
System limits
TPM cannot warn you of sudden serious
tire damage caused by external influ-
ences.<
The system does not function properly if it has
not been reset, e.g. a flat tire is reported despite
correct tire inflation pressures.

Technology for comfort, convenience and safety
92 The system is inactive and cannot display a flat
tire if a wheel has been mounted without TPM
electronics or if TPM experiences temporary
interference from other systems or devices that
use the same radio frequency.
Status display on Control Display
The tire and system status is indicated by the
color of the tires.
TPM takes the fact that the tire pressure
changes during driving into account. A correc-
tion is only required if the color of the TPM dis-
play indicates that it is necessary.
Green
The tire pressure matches the learned set state.
"Status: TPM active" is displayed on the Con-
trol Display.
A wheel is yellow
There is a flat tire or a major drop in inflation
pressure in the indicated tire. A message
appears on the Control Display.
All wheels are yellow
There is a flat tire or a major drop in inflation
pressure in several tires. A message appears on
the Control Display.
Gray
The system cannot detect a flat tire.
Reasons for this can include:
>TPM is being reset
>Temporary interference due to systems or
devices that use the same radio frequency
>Malfunction
Resetting system
Reset the system again after each correc-
tion of the tire inflation pressure and after
every tire or wheel change.<
Resetting finishes during driving and which can
be interrupted at any time. When driving
resumes, resetting is continued automatically.iDrive, for principle details, refer to page16.
1.Press the button to open the start
menu.
2.Move the controller toward "Settings".
3.Select "Vehicle" and press the controller.
4.Select "TPM" and press the controller.
5.Start the engine, but do not begin to drive.
6.Select "RESET" and press the controller.
7.Select "YES" and press the controller.
8.Start to drive.
The tires are shown in gray and "Status:
Resetting TPM..." is displayed.
After a few minutes of driving, the set tire infla-
tion pressures in the tires are applied as the set
values to be monitored. Resetting finishes dur-
ing driving. The tires are shown in gray on the
Control Display and "Status: TPM active" is dis-
played again.
If a flat tire is detected during resetting
and applying the tire inflation pressures,
all tires are shown in yellow on the Control Dis-
play. The message "Status: Tire low!" is dis-
played.<

Low tire pressure message
The warning lamp lights up yellow. A
message appears on the Control Dis-
play. In addition, a signal sounds. A flat
tire or a major air loss has occurred.
1.Reduce speed and stop the vehicle care-
fully. Avoid sudden braking and steering
maneuvers.
2.Check whether your vehicle is equipped
with standard tires or run-flat tires.
You will recognize run-flat tires by a
circular symbol containing the letters
RSC on the side of the tire, refer to
page199.<
Standard tires
1.If all four wheels are shown in yellow, iden-
tify the damaged tire on the vehicle.
2.Replace the damaged wheel or wheels,
refer to Changing wheels on page209.
The spare wheel is equipped with the neces-
sary TPM electronics and when mounted, will
also be monitored once the system has been
reset.
Have the tire replaced by a BMW center or a
workshop that is familiar with handling TPM and
works according to BMW repair procedures
with correspondingly trained personnel.
Run-flat tires*
1.Cautiously reduce speed to below 50 mph/
80 km/h. Avoid sudden braking and steer-
ing maneuvers. Do not exceed a speed of
50 mph/80 km/h.
If the vehicle is not equipped with run-
flat tires, refer to page199, do not
continue to drive. Continued driving after a
flat tire can result in serious accidents.<
2.In the event of complete tire pressure loss,
0 psi/0 kPa, you can estimate the possible
distance for continued driving on the basis
of the following guide values:
>With a light load:
1 to 2 persons without luggage:
approx. 155 miles/250 km>With a medium load:
2 persons, luggage compartment full, or
4 persons without luggage:
approx. 95 miles/150 km
>With a full load:
More than 4 persons, luggage compart-
ment 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 tracking stability 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; otherwise, pieces of the tire could
come loose and cause an accident. Do not con-
tinue driving, but instead contact your BMW
center.<
Malfunction
The yellow warning light flashes and
then lights up continuously. The tires
are shown in gray on the Control Dis-
play and a message is displayed. No flat tire can
be detected. Have system checked.
A message like this is displayed in the following
situations:
>When a malfunction is occurring.
Have the system checked.
>If a wheel without TPM electronics is
mounted.
>If TPM is temporarily interfered with by
other systems or devices which use the
same radio frequency.

Protective action
To ensure that the safety systems con-
tinue to provide optimized protection,
please follow the adjustment instructions on
page43.<
The front airbags help protect the driver and
front passenger by responding to frontal
impacts in which safety belts alone cannot pro-
vide adequate restraint. When needed, the
head and side airbags help provide protection in
the event of side impact. The relevant side air-
bag supports the side upper body area. The
head air bag supports the head. The knee air-bags help protect the legs against impact
against the cockpit.
The airbags are deliberately not triggered in
every impact situation, e.g. less severe acci-
dents or rear-end collisions.
Do not apply adhesive materials to the
cover panels of the airbags, cover them or
modify them in any other way.
Do not attempt to remove the airbag retention
system from the vehicle. Never modify or
tamper with either the wiring or the individual
components in the airbag system. This cate-
gory includes the upholstery in the center of the
steering wheel, on the instrument panel, the
doors and the roof pillars along with the sides of
the headliner. Do not attempt to remove or dis-
mantle the steering wheel.
Do not touch the individual components
directly after the system has been triggered,
because there is a danger of burns. In the event
of malfunctions, deactivation, or triggering of

Manually switching between high and
low beams
You can intervene at any time you wish or the
situation requires.
>If the high-beam assistant has switched on
the high beams, but you want to use the low
beams, simply switch to the low beams with
the turn signal lever. The high-beam assis-
tant is deactivated in the process.
To reactivate the system, briefly press the
turn signal lever in the high beam direction
again.
>If the high-beam assistant has switched on
the low beams, but you want to use the high
beams, switch to the high beams in the
accustomed manner. The system is deacti-
vated in the process and you must switch to
the low beams manually.
To reactivate the system, briefly press the
turn signal lever in the high beam direction
again.
>You use the headlamp flasher as usual with
low beams.
System limits
The high-beam assistant cannot replace
personal decisions on the benefits of
using the high beams. In situations which
require this, you should therefore switch to the
low beams manually to avoid a safety risk.<
In the following example situations, the system
either does not operate or only operates to a
limited degree and a personal reaction may be
required:
>Under extremely unfavorable weather con-
ditions, such as heavy fog or precipitation.
>For perceiving road users with poor lighting
of their own, e.g. pedestrians, cyclists, peo-
ple on horseback, horse-drawn vehicles,
with train or ship traffic close to the road and
wild animals crossing the road.
>In tight curves, on steep crowns or depres-
sions, with cross traffic or partially con-
cealed oncoming traffic on the freeway.
>In poorly lit places and with highly reflective
signs.>In the low speed range.
>When the windshield is dirty or covered with
stickers, decals etc. in the area of the inside
rearview mirror.
>When the sensor is dirty. Clean the sensor
on the front side of the inside rearview mir-
ror with a cloth moistened with a small
amount of glass cleaner.
Fog lamps
Briefly press the button to switch on/off.
Front fog lamps
The parking lamps or low beams must be
switched on for the fog lamps to operate. The
green indicator lamp on the Info Display lights
up whenever the fog lamps are on.
If the automatic headlamp control is acti-
vated, the low beams will come on auto-
matically when you switch on the fog lamps.<
