Radio Reception; Safety Belt Tensioner - BMW Z3 COUPE 2001 Manual

ASC+T/DSC
*
Precision sensors monitor the number of
revolutions of the wheels. When
equipped with DSC, they also monitor
steering angle, lateral acceleration,
brake pressure and the movement of the
vehicle around its vertical axis.
If differences in the wheel speeds occur,
ASC+T recognizes the danger of wheel-
spin and reduces the torque flow. If
necessary, the system also responds
with additional applications of the brakes
at the rear wheels.
In addition, DSC permanently monitors
the vehicle's current operating condition
and compares it with an ideal condition
that is calculated from the sensor's
signals. If deviations from this occur
(understeering or oversteering, for
instance), DSC can stabilize the vehicle
in fractions of a second by reducing
engine output and with the assistance of
braking intervention at individual wheels.
As a result, dangerous skids can be
prevented even as they are just begin-
ning. All of this is possible, of course,
only within physically possible limits.
You may need some time to become
accustomed to this system's interven-
tion. However, it provides optimum
propulsive force and driving stability.
The braking intervention may be accom-
panied by a certain degree of noise.

Radio reception

The AM frequency bands (medium-
wave, long-wave and short-wave) make
it possible to receive stations from a
great distance, because the broadcast
signals travel not only along the ground
as surface waves, but also as atmos-
pheric waves that are reflected from the
ionosphere.
Frequency-modulation (FM) provides
substantially better sound quality than
AM. However, because FM transmis-
sions rely on line-of-sight broadcast
waves, their effective reception range
is limited.
The limitations which are inherent to
radio reception in a moving vehicle
have been minimized by the use of
innovative systems.

Safety belt tensioner

The safety belt tensioner responds to
severe collisions by tightening the belts
to ensure that occupants remain firmly
positioned in their seats. A gas-pres-
sure system retracts the buckle
assembly to tension the shoulder and
lap belts within fractions of a second.
This tends to further reduce the
tendency to slide under the lap belt.
