Use unleaded gasoline only.
Fuels containing up to 10% ethanol or
other oxygenates with up to 2.8% ox-
ygen by weight (i.e. 15% MTBE or
3% methanol plus an equivalent
amount of co-solvent) will not void the
applicable warranties with respect to
defects in materials or workmanship.
Field experience has indicated signifi-
cant differences in fuel quality (i.e.,
volatility, composition, additives, etc.)
among gasolines offered for sale in the
United States and Canada. The use of
poor-quality fuels may result in driving,
starting and stalling problems espe-
cially under certain environmental
conditions, such as high ambient tem-
perature and high altitude.
Should you encounter problems while
driving that you suspect could be
related to the fuel you are using,
we recommend 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 simulta-
neously acquire the assurance that
they have been thoroughly tested by
BMW to ensure optimum performance
when installed on your vehicle.
BMW warrants these parts to be free
from defects in material and work-
manship.
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 Accesso-
ries and other products approved by
BMW, together with professional
advice on using these items, are avail-
able from all BMW Retailers.Installation and operation of non-BMW
approved accessories such as alarms,
radios, amplifiers, radar detectors,
wheels, suspension components,
brake dust shields, telephones
(including operation of any portable
cellular phone from within the vehicle
without using an externally mounted
antenna) or transceiver equipment
(e.g., C.B., walkie-talkie, ham radio or
similar) may cause extensive damage
to the vehicle, compromise its safety,
interfere with the vehicleÕs electrical
system or affect the validity of the
BMW Limited Warranty.
See your authorized BMW Retailer for
additional information.
Do not use key or remote control to
lock doors or luggage compartment
with anyone inside the car.
"Maintenance, replacement or repair
of the emission control devices and
systems may be performed by any
automotive repair establishment or
individual using any certified automo-
tive part."

The reception and sound quality
obtained from mobile radios varies
according to a variety of factors, includ-
ing the broadcast range of the transmit-
ter and the directional orientation of the
antenna.
Interference factors such as high-ten-
sion power lines, buildings and natural
obstructions can all lead to unavoidable
reception interference, regardless of
how well the vehicle's sound system is
operating.
Climatic factors such as intense solar
radiation, fog, rain and snow can also
interfere with reception.
Cellular telephones without ofÞcial BMW
approval can generate radio interfer-
ence. This is noticeable
e.g.,
as a low-
pitched hum in the loudspeakers.
Please refer to the supplementary oper-
ating instructions provided with your
sound system for detailed information
on its use.Mobile communications devices (mo-
bile phones, two-way radios, etc.) not
specifically designed for use in your car
may trigger malfunctions in other vehic-
ular systems. BMW can neither test nor
assume responsibility for every individ-
ual product being offered on the mar-
ket. We recommend that you consult
your BMW Retailer before purchasing
any device of this kind.
To ensure that your BMW continues to
provide reliable and trouble-free opera-
tion, refrain from using a cellular tele-
phone or other radio device with an
antenna located inside the passenger
compartment. The antenna should
always be mounted on the outside of
the vehicle.

Before loading the vehicle on a
train or driving it through a car-wash,
remove the antenna.c

AM provides substantially longer recep-
tion ranges than FM. AM broadcast sig-
nals, propagated at ground level in the
form of surface waves, are also reßected
from the ionosphere as atmospheric
waves.
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. Although numerous factors combine to
impose inherent limitations on the
reception quality available from mobile
radios, specially designed systems can
be employed to minimize their effects:
The Antenna Diversity system employs
several FM antennas integrated within
the rear window to provide three sepa-
rate sources for receiving broadcast
waves. An integral processor automati-
cally selects the antenna with the best
FM reception quality at any given time.
Because the ongoing antenna selection
process is completed within millisec-
onds, it remains inaudible to the radio
listener. The safety belt tensioner responds to
collisions by tightening the belts to
ensure that occupants remain firmly
positioned in their seats. A gas-pres-
sure system retracts the buckle assem-
bly to tension the shoulder and lap belts
within fractions of a second, preventing
the driver and passenger from slipping
forward.360de084
