Technology for comfort, convenience and safety
92 Active stabilizers at the front and rear axles
form the basis for Dynamic Drive. Suspen-
sion compliance adapts to suit driving
conditions, varying from performance-
oriented during cornering to smooth and
comfort-oriented when the vehicle is
proceeding in a straight line.
The system assumes operational status
each time you start the engine.
Driving with Dynamic Drive During vehicle operation, the system
continuously runs through closed-loop
control cycles lasting only fractions of a
second. In case of malfunction
The symbol will light up, accompa-
nied by a status message in the
Check Control panel. Please take
note of the additional information in the
Control Display panel.
You can find more detailed information on
the Check Control starting on page 80.
If the Dynamic Drive system switches
off in response to malfunction, please
remember to adapt your speed accord-
ingly, especially in curves.
The suspension will be noticeably softer
and the vehicle will display a greater
tendency to tilt during cornering and in
crosswinds.
If a status message appears in the Check
Control panel, accompanied by a red
symbol, the hydraulic fluid in the reservoir
may have fallen to below the minimum
level, possibly owing to leakage in the
hydraulic system. Stop the vehicle and
switch off the engine immediately.
Please observe the additional instructions
provided in the Control Display panel.<
EDC Electronic Damping
Control*

The suspension responds to changes in
factors such as road surface, or operating
conditions such as steering and braking, by
adapting to the new conditions within frac-
tions of a second.Comfort program The system automatically assumes opera-
tion in its Comfort mode each time you start
the engine; this mode is suitable for use
throughout the vehicle's entire speed range
and regardless of load. Sport programActivate in "Settings" menu with the igni-
tion on.
You should select the Sport program for
consistently performance-oriented
response from shock absorbers and
steering. RDC Tire Pressure Monitor*The conceptRDC monitors inflation pressures in all four
tires while you drive. The system provides
an alert whenever the inflation pressure
drops significantly below the specified
pressure in one or more tires.
To initialize RDC, start by checking the
inflation pressures in all four tires and
comparing them with those specified in the
chart on page 171, correcting them as
necessary. Then proceed to initialize the
system.

This symbol will appear in the
Check Control panel to inform you
when the inflation pressure varies
from that stored in the system. A text
message appears at the same time. Please
take note of the additional information in
the Control Display panel.
You can find more information on the
Check Control starting on page 80.
The RDC cannot alert you to severe
and sudden tire damage caused by
external factors.<
To initialize the system 1.With the vehicle parked, switch on the
ignition
2.Select "RDC" from the "Settings" menu
and confirm your selection. The initializa-
tion menu appears. "INITIALIZE" 1.Select and confirm
2.RDC is initialized. A message appears in
the Check Control panel
3.After several minutes of driving RDC will
adopt the tires' current inflation pressures
as its references.
The current data appear in the Control
Display. These figures are more accurate than those that appear on the inflation
gauges at filling stations, etc.
The only time you will need to repeat this
procedure is after correcting your tire pres-
sures. Because RDC automatically
assumes operation each time you switch
on the ignition, it is on duty whenever you
drive.
If the system detects a flat tire during
the initialization process, the tires in
the Control Display will appear in red.<
Do not start initialization
Select and confirm to return to the
"Settings" menu.
Status indicators in the Control
Display The status of the system is indicated by the
color of the tires. GreenTire inflation pressures correspond to the
initialized level.YellowThe inflation pressures in the tires have
fallen to below the specified level, which is
normal in every tire after a certain amount
of time.
This alerts you to have the tires inflated to
the specified pressures as soon as
possible. RedPressure loss in indicated tire.
If this occurs, reduce vehicle speed imme-
diately and stop the vehicle. Avoid hard
and sudden steering and braking maneu-
vers. BlackThe system is being initialized.
The system needs several minutes to
complete the initialization process, after
which it is ready to detect and report tire
problems.

In the event of loss in tire pressure If the indicator lamp symbol in the Check
Control lights up in yellow, and a message
also appears, this indicates that the infla-
tion pressures in the tires have fallen to
below the specified level, which is normal
in every tire after a certain amount of time.
This alerts you to have the tires inflated to
the specified pressures as soon as
possible.
Please take note of the additional informa-
tion in the Control Display panel.
If you are prompted to check the tire
pressure shortly after a correction has
been made, this indicates that the
corrected values were not accurate. Please
check the inflation pressure again and
make corrections according to the inflation
pressure table. Then reinitialize the
system.< Flat tire If you have a flat tire, the indicator lamp
symbol in the Check Control will light up in
red, and a message will appear. In addition,
a gong sounds.
If this occurs, reduce vehicle speed imme-
diately and stop the vehicle. Avoid hard
and sudden steering and braking maneu-
vers. Replace the damaged tire.
The spare tire provided with your
vehicle is equipped with the elec-
tronics required to support RDC operation;
once the spare tire is installed, the pressure
in this tire will also be monitored following
system initialization.
Have the tires changed at your BMW
center. Your BMW center has the informa-
tion needed for working with RDC and is
equipped with the necessary special
tools. radio frequency as RDC can generate inter-
ference signals that may prevent the
system from operating as intended. The symbol will appear in yellow in the
Check Control panel and a message will
appear.
You will also see the same message
>in the event of a system fault
>if a wheel is mounted without the
appropriate electronics
>if, in addition to the spare tire, additional
wheels with RDC electronics are on board.
Please refer to the additional information
supplied in the Control Display, and have
the system inspected at your BMW center.
Self-leveling suspension*

In the event of malfunction
A Check Control message
appearing together with this symbol
indicates a malfunction in the self-
leveling suspension. Please take note of
the additional information in the Control
Display panel.
Stop and inspect the vehicle. If the rear of
the vehicle is visibly lower than the front,
possibly accompanied by a tilt noticeable
when you compare the left rear with the
right rear, you should respond by immedi-
ately proceeding to the nearest BMW
center. Drive with appropriate caution in
the meantime. The vehicle has reduced
ground clearance and driving comfort may
be noticeably reduced. Even if the attitude
of the vehicle is normal, you should consult
the nearest BMW center if the warning
lamp indicates a system fault.
Adaptive brake lamp The adaptive brake lamp indicates the
intensity with which you are applying your
brakes to drivers of following vehicles.

Wheels and tires

Wheels and tiresTire inflation pressure Information for your safety The factory-mounted radial tires have been
specially selected to provide optimal
performance when installed on your
vehicle; if properly cared for they will
furnish a combination of tremendous safety
and excellent ride comfort.
It is not merely the tire's service life, but
also driving comfort and Ð above all else Ð
driving safety that depend on the condition
of the tires and the maintenance of the
specified tire pressure.
Incorrect inflation pressure is a frequent
cause of tire damage. Tire inflation pres-
sures also have a substantial effect on your
BMW's handling response.
Check tire inflation pressures regu-
larly Ð at least every two weeks and
before beginning a longer trip. If you fail to
observe this precaution you may be driving
on tires with incorrect tire pressures, a
condition that can not only compromise
your vehicle's stability, but also lead to tire
damage and the risk of an accident.
Remember to check the inflation pressure
in your spare tire. Inflate the spare tire to
the highest pressure specified for any tire
on the vehicle.<
The inflation pressures, provided on a label
affixed to the B-pillar, are visible when the
driver's door is open.
To check tire pressures The table on the next page provides the
correct inflation pressures for cool
(ambient temperature) tires in psi/kilo-
pascal.
Vehicles with RDC Tire Pressure Monitor:
Remember to reactivate the system after
correcting your tire pressures, refer to
page 92. Comply with tire approval
specificationsThe inflation pressures in the table apply to
tire sizes and tires from BMW-approved
manufacturers. Your BMW center is familiar
with these pressures. Higher pressures
may be specified for tires from other manu-
facturers.

BMW 745i, 745LiTire condition Tire tread Ð Tire damageInspect your tires frequently for tread wear,
signs of damage and for foreign objects
lodged in the tread. Check the tread depth.
Tread depth should not be allowed to go
below 0.126 in (3 mm), even though the
legally specified minimum tread depth is
only 0.063 in (1.6 mm). The locations of the
tread wear indicators are indicated by the
letters TWI at various points on the side of
the tire; when the tread wears to a depth of
0.063 in (1.6 mm), the wear indicators
appear to warn you that the tread has worn
to the minimum legal level. At tread depths
below 0.126 in (3 mm) there is an increased
risk of aquaplaning, even when only small
amounts of water are present on the road
surface. Never attempt to continue driving on
a flat tire. Because a flat tire will seri-
ously impair your vehicle's handling and
braking response, attempts to drive on a
flat tire can lead to loss of control over the
vehicle.
To avoid loading the tires beyond their
approved carrying capacity, never overload
the vehicle. Overloading can lead to over-
heating and increases the rate at which
damage develops inside the tires. The ulti-
mate result can assume the form of a
sudden air loss.
Unusual vibrations during vehicle opera-
tion, of the kind that can be caused by
contact with curbs, etc., may indicate that
a wheel, tire or other vehicle component is
damaged. These kinds of problems may
also be signalled by other changes in
vehicle response, such as a strong
tendency to pull to the left or right. Should
this occur, respond by immediately
reducing your speed. Carefully proceed or
have your vehicle towed to the nearest
BMW center or tire dealer to have the
wheels and tires inspected.
Tire damage, extending to sudden and
complete loss of pressure in extreme
cases, can pose a potentially lethal safety
hazard for the vehicle's occupants and
other road users alike.< Tire specifications

Tire replacement To maintain good handling and vehicle
response, use only tires of a single tread
configuration from a single manufacturer.
BMW tests and approves specific wheel
and tire combinations. DOT Quality Grades Treadwear
Traction AA A B C
Temperature A B C
All passenger car tires must conform
to Federal Safety Requirements in
addition to these grades.< TreadwearThe treadwear grade is a comparative
rating based on the wear rate of the tire
when tested under controlled conditions
on a specified government test course.
For example, a tire graded 150 would wear
one and one-half (1g) times as well on the
government course as a tire graded 100.
The relative performance of tires depends
upon the actual conditions of their use,
however, and may depart significantly from
the norm due to variations in driving habits,
service practices and differences in road
characteristics and climate.TractionThe traction grades, from highest to lowest,
are AA, A, B, and C.
Those grades represent the tire's ability to
stop on wet pavement as measured under
controlled conditions on specified govern-
ment test surfaces of asphalt and concrete.
A tire marked C may have poor traction
performance.
The traction grade assigned to this
tire is based on straight-ahead
braking traction tests, and does not include
acceleration, cornering, hydroplaning, or
peak traction characteristics.< TemperatureThe temperature grades are A (the highest),
B, and C, representing the tire's resistance 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 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 separately or in combina-
tion, can cause heat buildup and possible
tire failure.<
Uniform Tire Quality Grading Quality grades can be found where appli-
cable on the tire sidewall between tread
shoulder and maximum section width. For
example:
Treadwear 200 Traction AA
Temperature A
Do not use retreaded tires, since
driving safety may be impaired.
Possible variations in the design and the
age (which could be substantial) of the
carcasses can lead to unusually rapid
wear.< Tire age The tire's date of manufacture is indicated
on the sidewall:
DOT ... 4901 indicates that a tire was
manufactured in week 49 of the year 2001.
Regardless of milage or wear, BMW
recommends that you replace all tires Ð
including the spare tire Ð after a maximum
of 6 years, even though the tires may have
a theoretical service life of up to 10 years.

Wheel and tire
combinationsThe right choice
Use only wheel and tire combinations
that BMW has 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.<
BMW tests certain tire brands for each tire
size, classifies them as road-safe and
approves them. Consult your BMW center
for more information. Observe any country-
specific regulations, e.g. on making a
corresponding entry in the vehicle
documents.
The correct combination of wheels
and tires is a vital factor in ensuring
reliable operation of various vehicle
systems such as ABS and DSC.
It is therefore important to ensure that tires
from a single manufacturer with a single
tread configuration are always mounted on
all vehicle wheels. After a flat tire, always
remember to have the specified wheel and
tire combination remounted on the vehicle
as soon as possible.<
Storage Always store wheels and tires in a cool, dry
place with as little exposure to light as
possible. Always protect tires against all
contact with oil, grease and fuels.
Special characteristics of
winter tires Choosing the right tire BMW recommends winter tires Ð M+S
radial tires for use in cold winter driving
conditions. Although all-season M+S tires
provide better winter traction than standard
summer tires with H, V, W and ZR speed
ratings, they generally fail to provide the
same levels of cold-weather performance
as winter tires.
When mounting, always install winter tires
of a single tread configuration and from a
single manufacturer on all four wheels to
ensure safe tracking and secure steering
response. Observe speed ratings
Never exceed the maximum speed for
which the tires are rated.
Unprofessional attempts by laymen to
service tires can lead to damage and acci-
dents.
Have this work performed by skilled
professionals only. The technicians at your
BMW center will be glad to assist you with
the required professional knowledge and
specialized equipment.<
Tire condition, tire pressure Because winter tires display a noticeable
loss in their ability to cope with cold-
weather driving conditions once the tread
wears to below 0.16 in (4 mm), to ensure
continued safety you should always have
such tires replaced.
Always maintain the specified inflation
pressures in all tires, and remember to
have the wheel and tire assemblies
balanced every time either a wheel or a tire
is replaced. Snow chains*

Safety precautions to observe in the
event of a flat tire 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 move the
transmission's selector lever to P.
Have all vehicle occcupants get out of the
vehicle and ensure that they remain outside
the immediate 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 vehicle.
Comply with all safety guidelines and regu-
lations.
Change the wheel only on a level, firm
surface which is not slippery. The vehicle or

additional precautions to secure the
vehicle from rolling.
3.Loosen the lug bolts 1/2 a turn
4.Set up the jack beneath the jacking
point closest to the flat tire. Ensure that the
entire surface of the jack's base is in firm
contact with the ground and that the jack
itself is standing completely vertical (not
tilted), and that the fitting on the top of the
jack will align with the rectangular recess
on the vehicle when you raise it, refer to
illustration
5.Jack the vehicle up until the wheel you
are changing is raised from the ground
6.Unscrew the lug bolts and remove the
wheel
7.Remove accumulations of mud or dirt
from the mounting surfaces of the wheel
and hub. Clean the lug bolts
8.Position the spare wheel. Secure the
wheel by turning at least two lug bolts into
opposite bolt holes
9.Screw in the remaining lug bolts.
Tighten all the bolts securely in a diagonal
pattern
10.Lower the jack and remove it from
beneath the vehicle.
11.Tighten the lug bolts in a diagonal
pattern
12.Check and correct the tire inflation
pressure at the earliest opportunity.
Protect valve stems and valve stem
seal caps against dirt and contamina-
tion. Dirt in valve stems is a frequent source
of gradual air loss.
Vehicles with RDC Tire Pressure Monitor:
After mounting a spare tire or correcting the inflation pressure(s) always remember
to reinitialize the system, refer to page 92.
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.
To ensure safety, always have the lug bolts
checked with a calibrated torque wrench to
ensure that they are tightened to the spec-
ified torque of 140 Nm as soon as
possible.<
Reverse the removal sequence to store the
wheel and tools in the vehicle.
When you mount wheels other than Orig-
inal BMW light-alloy wheels, different lug
bolts may also be required.
Always have damaged tires replaced and
the wheel and tire assembly rebalanced at
the earliest possible opportunity.
Battery Battery care The battery is 100% maintenance-free, i. e.,
the electrolyte will last for the life of the
battery when the vehicle is operated in a
temperate climate.
For all questions that regard the
battery, please consult your BMW
center. Since the battery is maintenance-
free, the following is for your information
only.< Charging the battery Only charge the battery in the vehicle via
the terminals in the engine compartment
with the engine off. Connections, refer to
Jump starting on page 187.
To avoid short circuits, as well as
possible fires and personal injury,
always disconnect the cable from the
battery's negative terminal before working
on the vehicle's electrical system.<
