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.

Technology for comfort, convenience and safety

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.

Things to remember when driving

Things to remember when drivingBreak-in procedures To ensure that your vehicle continues to
furnish optimal economy of operation
throughout an extended service life, we
request that you devote careful attention to
the following section. Engine and differential The first 1,200 miles (2,000 km):
During this initial period you should attempt
to avoid constant, steady-state operation
and vary both vehicle and engine speeds
as often as possible. Until the break-in
period has been completed you should
also refrain from exceeding the following:
>4500 rpm and 105 mph (170 km/h)
Always obey all official speed limits.
Avoid full-throttle operation and use of the
transmission's kickdown mode during
these initial miles.
After the first 1,200 miles (2,000 km) you
can gradually increase both engine and
vehicle speeds to their respective maxima.
You should also comply with these break-in
procedures if the engine or differential is
replaced at a later point. Tires Due to technical factors associated with
their manufacture, tires do not achieve their
full traction potential until after an initial
break-in period. We thus urge you to drive
with extra care during the first 200 miles
(300 kilometers). Brake system Brakes require an initial break-in period of
approx. 300 miles (500 km) to achieve
optimal contact and wear patterns
between brake pads and rotors.
General driving notes High temperatures
Extreme temperatures occur at the
catalytic converter on this and every
catalyst-equipped vehicle. Do not remove
the heat shields installed adjacent to
various sections of the exhaust system,
and never apply undercoating to them.
When driving, standing at idle and while
parking take care to avoid possible contact
between the hot exhaust system and any
highly flammable materials such as hay,
leaves, grass, etc. Such contact could lead
to a fire, and with it the risk of serious prop-
erty damage as well as personal injury.<
Parking the vehicle Condensation forms in the air conditioner
system during operation, and then exits
under the vehicle. Traces of condensed
water under the vehicle are thus normal.Aquaplaning
When driving on wet or slushy roads,
reduce road speed. If you do not, a
wedge of water can form between tires and
road surface. This phenomenon is referred
to aquaplaning, and is characterized by a
partial or complete loss of contact between
tires and road surface, ultimately under-
mining your ability to steer and brake the
vehicle.<
Water-covered streets
Do not drive through water on the
road if it is deeper than 1 foot (30 cm),
and then only at walking speed at the most.
Otherwise, the vehicle's engine, the elec-
trical systems and the transmission may be
damaged.<

Mobility
This section helps you maintain your
mobility by supplying important
information on vital topics including
fuels and lubricants, wheels and tires,
service, maintenance and how to deal
with any problems that may occur.

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
