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 (i.e. 15  % 
MTBE or 3 % methanol plus an equiva-
lent amount of co-solvent) will not void 
the applicable warranties covering 
defects in materials or workmanship. 
Field experience has indicated signifi-
cant differences in fuel quality (volatility, 
composition, additives, 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, espe-
cially under certain environmental 
conditions, such as high ambient 
temperature and high altitude.
Should you encounter driveability prob-
lems that you suspect could be related 
to the fuel you are using, we recom-
mend that you respond by switching to 
a recognized high-quality brand.
Failure to comply with these recom-
mendations may result in unscheduled 
maintenance.
Follow all applicable 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 
optimum 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 confirm that 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 
operation 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 
accessories) may cause extensive 
damage 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 BMW 
center for additional information.

There is an extended-life battery 
in every master key that is 
charged automatically in the ignition 
lock as you drive. 
For this reason, if you have a master 
key that is not in regular use, you 
should use that key approx. once every 
year while driving for an extended 
period. This will charge the battery.

Activation from inside does not lock the 
fuel filler door (refer to page 37). Activa-
tion from outside simultaneously arms 
the anti-theft system. The alarm system 
is also activated or deactivated.
When you use the central locking 
system to lock the doors from inside 
the vehicle, it will automatically disen-
gage the locks if an accident occurs, 
except on doors that have been locked 
individually using the lock buttons, refer 
to page 37. The accident response 
routine also includes automatic activa-
tion of the hazard warning flashers and
