change wheel BMW 745Li 2006 E66 User Guide

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.

Wheels and tires
198
Temperature
The temperature grades are A, B, and C, A
being highest, and represent the tire's resis-
tance to the generation of heat and its ability to
dissipate heat when tested under controlled
conditions on a specified indoor laboratory test
wheel.
Sustained high temperature can cause the
material of the tire to degenerate and reduce
tire life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds to
a level of performance which all passenger car
tires must meet under the Federal Motor Vehi-
cle Safety Standard No. 109. Grades B and A
represent higher levels of performance on the
laboratory test wheel than the minimum
required by law.
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Excessive speed,
underinflation, or excessive loading, either sep-
arately or in combination, can cause heat
buildup and possible tire failure.<
RSC 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.
M+S
Winter and all-season tires.
These have better winter properties than sum-
mer tires.
XL
Indicates specially reinforced tires.
Tire condition
Inspect your tires frequently for tread depth,
signs of damage and for foreign objects lodged
in the tread. Check the tread depth.
Minimum tread depth
The tread depth should not fall below 0.12 in/
3 mm, although, for example, European legisla-
tion only specifies a minimum tread depth of 0.063 in/1.6 mm.
At tread depths below 0.12 in/3 mm, there is an
increased risk of high-speed hydroplaning,
even when only small amounts of water are
present on the road surface.
Winter tires display a noticeable loss in their
ability to cope with cold-weather driving condi-
tions once the tread wears to below 0.16 in/
4 mm. To ensure continued safety, you should
always have such tires replaced.
Wear indicators at the tread-groove base, refer
to arrow, are distributed over the tire's circum-
ference and are marked on the side of the tire
with TWI – Tread Wear Indicator. If the tire tread
has been driven down to the wear indicators, a
tread depth of 0.063 in/1.6 mm has been
reached.
Wheel/tire damage
Please note that low profile tires make wheels,
tires, and suspension parts more susceptible to
road hazards and consequential damages.
Unusual vibrations encountered during normal
vehicle operation can indicate tire failure or
some other vehicle defect. This can, for exam-
ple, be caused by driving over curbs. These
kinds of problems may also be signaled by other
changes in vehicle response, such as a strong
tendency to pull to the left or right.
In these cases, reduce speed immedi-
ately and have wheels and tires thor-
oughly checked. Drive carefully to the nearest
BMW center or tire shop that works according
to BMW repair procedures with correspond-
ingly trained personnel. If necessary, have the
vehicle towed there.
Tire damage can be extremely dangerous for
vehicle occupants and other road users.<

Backup lamp:
Bulb 16 watts, W 16 W
1.Pull the bulb holder out.
2.Extract the bulb for replacement.
Changing wheels
Safety precautions to observe in the
event of a flat and during all tire changes:
Park the vehicle as far as possible from passing
traffic. Park on a firm, flat, surface. Switch on the
hazard warning flashers.
Engage the parking brake and shift the trans-
mission selector lever into P.
Have all vehicle occupants get out of the vehicle
and ensure that they remain outside the imme-
diate area in a safe place, such as behind a
guardrail.
If a warning triangle or portable hazard warning
lamp is required, set it up on the roadside at an
appropriate distance from the rear of the vehi-
cle. Comply with all safety guidelines and regu-
lations.
Change the wheel only on a level, firm surface
which is not slippery. The vehicle or the jack
could slip to the side if you attempt to raise the
vehicle on a soft or slippery surface such as
snow, ice, tile, etc.
Position the jack on a firm support surface. Do not use a wooden block or similar object as a
support base for the jack, as this would prevent
it from extending to its full support height and
reduce its load-carrying capacity.
To avoid serious or fatal injury, never lie under
the vehicle and never start the engine while it is
supported by the jack.<
What you will need
To avoid rattling noises, note the positions of
the tools before removing them, then return
them to their initial positions after completing
work.
>Lug wrench
Located beside the spare wheel.
>Wheel chock
Located next to the spare wheel, or behind
the trim panel on the left side of the luggage
compartment on vehicles equipped with a
trailer coupling.
Remove the floor mat and the cover above
the spare tire.
Unscrew the wingnut and remove the wheel
chock.

Replacing components
210 >Vehicle jack
Located in the luggage compartment
behind the right-hand side panel.
Grasp the handle in the upper panel and fold
it down.
Loosen the wingnut and remove the jack.
After use, screw the jack all the way back
down and snap the handle back into place.
Spare tire
1.Loosen the wing nut 1.
2.Remove the washer 2 from the side.
3.Completely unscrew the threaded rod 3.
4.Remove the spare tire.
Preparing for a wheel change
1.Read carefully and comply with the safety
precautions on page209.
2.Secure the vehicle to prevent it from rolling:
Place the wheel chock against the rear sur-
face of the front tire on the side opposite the
side being raised. If the vehicle is parked on
a downward slope, place the wheel chock
securely in front of the tire. On a steep
grade, also secure the vehicle against roll-
ing.
3.Loosen the lug bolts a half turn.
Lifting vehicle
1.Position the jack at the jacking point closest
to the wheel so that the entire jack base
makes contact vertically under the jacking
point.
The vehicle jack is designed for
changing wheels only. Do not attempt
to raise another vehicle model with it or to
raise any load of any kind. To do so could
cause accidents and personal injury.<
2.Guide the jack head into the rectangular
recess of the jacking point when cranking
up the jack, refer to section of illustration.
3.Jack the vehicle up until the wheel you are
changing is raised from the ground.
Mounting a wheel
1.Unscrew the lug bolts and remove the
wheel.
2.Remove accumulations of mud or dirt from
the mounting surfaces of the wheel and
hub. Clean the lug bolts.
3.Position the new wheel or spare tire on the
hub and screw in at least two bolts diago-
nally.
When you mount wheels other than Genu-
ine BMW light-alloy wheels, different lug
bolts may also be required.
4.Screw in the remaining lug bolts. Tighten all
the bolts securely in a diagonal pattern.
5.Lower the vehicle and remove the jack from
beneath the vehicle.
