For your own safety
Use unleaded gasoline only. Fuels
containing up to and including
10 % Ethanol or other oxygenates with
up to 2.8 % oxygen by weight (that is,
15 % MTBE or 3 % methanol plus an
equivalent amount of co-solvent) will
not void the applicable warranties re-
specting defects in materials or work-
manship. Field experience has indi-
cated significant differences in fuel
quality (volatility, composition, addi-
tives, etc.) among gasolines offered for
sale in the United States and Canada.
The use of poor quality fuels may result
in driveability, starting and stalling
problems especially under certain envi-
ronmental conditions such as high am-
bient temperature and high altitude.
Should you encounter driveability prob-
lems which you suspect could be re-
lated to the fuel you are using, we rec-
ommend that you respond by switching
to a recognized high-quality brand.
Failure to comply with these recom-
mendations may result in unscheduled
maintenance.
Follow the relevant safety rules when
you are handling gasoline.

Important safety information.
For your own safety, use genuine parts
and accessories approved by BMW.
When you purchase accessories tested
and approved by BMW and Original
BMW Parts, you simultaneously acquire
the assurance that they have been thor-
oughly tested by BMW to ensure opti-
mum performance when installed on
your vehicle.
BMW warrants these parts to be free
from defects in material and workman-
ship.
BMW will not accept any liability for
damage resulting from installation of
parts and accessories not approved by
BMW.
BMW cannot test every product from
other manufacturers to verify if it can be
used on a BMW safely and without risk
to either the vehicle, its operation, or its
occupants.
Original BMW Parts, BMW Accessories
and other products approved by BMW,
together with professional advice on
using these items, are available from all
BMW centers.
Installation and operation of non-BMW
approved accessories such as alarms,
radios, amplifiers, radar detectors,
wheels, suspension components, brake
dust shields, telephones (including op-
eration of any portable cellular phone
from within the vehicle without using an
externally mounted antenna) or trans-
ceiver equipment (for instance, CBs,
walkie-talkie, ham radio or similar ac-
cessories) may cause extensive dam-
age to the vehicle, compromise its
safety, interfere with the vehicle's elec-
trical system or affect the validity of the
BMW Limited Warranty. See your au-
thorized BMW center for additional in-
formation.

Maintenance, replacement, or
repair of the emission control de-
vices and systems may be performed
by any automotive repair establishment
or individual using any certified auto-
motive part.

Rain sensor
*
Integrated rear suspension
The rain sensor controls windshield
wiper operation, depending on how wet
the windshield is.
Infrared light is carried along the sur-
face of the windshield in an optical con-
ductor in such a manner that it is re-
flected completely when the windshield
is dry. The quantity of reflected light is
measured.
If the window is covered with beads of
water, the amount of light that is re-
flected is decreased since the infrared
light at the surface of the windshield
can then escape. The quantity of re-
flected light is thus a means of gauging
the degree of wetness on the wind-
shield. 390de133
When the system is set to the "Intermit-
tent" wiper speed, the wipers react im-
mediately Ñ if water is splashed onto
the windshield by vehicles traveling
ahead of you, for example. As a result,
the rain sensor provides a contribution
to driving safety and comfort.
This axle is based on the same multi-
link principle as that in series-7 vehi-
cles. The axle's kinematics and elastic
kinematics are critical for wheel control
Ñ a significant prerequisite for achieving
the objective of exceptional onroad
handling characteristics with this vehi-
cle concept.
In order to reduce unsprung mass, the
wheel carriers and the swing arm are
made of aluminum.
For an outstanding quality in acoustics
and vehicle oscillation characteristics,
the differential is isolated with double
elasticity through a chassis sub-frame
toward the vehicle body.
