2006 BMW 650I CONVERTIBLE oil pressure

Technology for comfort, convenience and safety
88
Dynamic Drive*
The concept
Dynamic Drive minimizes body roll and opti-
mizes vehicle stability during cornering and
evasive maneuvers.
Dynamic Drive is based on active stabilizers on
the front and rear axles. Suspension compli-
ance 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. During vehicle
operation, the system continuously runs
through closed-loop control cycles lasting only
fractions of a second.
The system assumes operational status each
time you start the engine.
Malfunction
The warning lamp lights up yellow and
a message is shown on the Control Dis-
play. There is a malfunction in the sys-
tem. Have the system checked as soon as pos-
sible.
If a malfunction occurs, please remember
to adapt your speed accordingly, espe-
cially 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 message stating that you should stop is
shown on the Control Display, stop at a suitable
location and switch off the engine as soon as
possible. In this case the oil level in the reservoir
may have dropped below the minimum, possi-
bly owing to a leak in the hydraulic system. Do
not continue driving, but instead contact your
BMW center.<
Flat Tire Monitor FTM
The concept
The Flat Tire Monitor keeps track of the infla-
tion pressures in the tires as you drive. The sys-
tem provides an alert whenever the inflation
pressure drops significantly in relation to the
pressure in another tire.
In the event of a pressure loss, the rolling radius
and therefore the rotation speed of the wheels
change. This change is detected and signaled
as a flat tire.
Functional requirement
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:
>System has not been initialized
>Driving on snow-covered or slippery roads
>Sporty driving style: slip in the drive wheels,
high lateral acceleration
>Driving with snow chains
*
Initializing system
The initialization finishes during driving,
which can be interrupted at any time.
When driving resumes, the initialization is auto-
matically continued.
Do not initialize the system when driving with
snow chains

Special characteristics of winter tires
BMW recommends winter tires for use in cold
winter driving conditions. Although all-season
M+S tires provide better winter traction than
summer tires, they generally fail to provide the
same levels of cold-weather performance as
winter tires.
Watch speed
Always observe the maximum permissi-
ble speed for the winter tires, otherwise
tire damage may occur, which can result in acci-
dents.<
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. Do not exceed the maximum
tire inflation pressure indicated on the side wall
of the tire.
Snow chains*
BMW only tests certain fine-link snow chains,
classifies them as road-safe and recommends
them. Consult your BMW center for more infor-
mation.
These snow chains are approved exclusively for
use in pairs on the rear wheels with the tire size:
>245/50 R 17 Y
>245/45 R 18 Y
Follow the chain manufacturer's instructions
when installing snow chains. Do not exceed a
vehicle speed of 30 mph/50 km/h with the
chains installed.
Do not initialize the Flat Tire Monitor after
installing snow chains as this could cause
the Flat Tire Monitor to malfunction.
When you are driving with snow chains, it can
be beneficial to switch off DTC briefly, refer to
page87.<
