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
equivalent amount of co-solvent) will
not void the applicable warranties
respecting defects in materials or work-
manship. Field experience has indi-
cated significant differences in fuel
quality (i.e. volatility, composition or
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 especially 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 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
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 made
by 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
operation of any portable cellular phone
from within the vehicle without using an
externally mounted antenna) or trans-
ceiver equipment (such as CB, walkie-
talkie, ham radio or similar) may cause
extensive damage to the vehicle,
compromise its safety, interfere with
the vehicle's electrical system or affect
the validity of the BMW Limited
Warranty. Consult your BMW center for
additional information.

<


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

Indicator and warning lamps

Technology that monitors itself

Indicator and warning lamps that are
identified by "

l

" are tested for proper
functioning whenever the ignition key is
turned. They each light up once for
different periods of time.
If a fault should occur in one of these
systems, the corresponding lamp does
not go out after the engine is started or
it lights up while the vehicle is moving.
You will see how to react to this in the
following section.

Red: stop immediately

Battery charge current

l

The battery is no longer being
charged. The alternator drive
belt is defective or there is a malfunc-
tion in the charging circuit of the alter-
nator. Please contact the nearest BMW
center.
If the drive belt is defective, stop
and switch off the engine immedi-
ately to prevent overheating and
serious engine damage. If the drive belt
is defective, increased steering effort is
also required.

<


Engine oil pressure

l

Stop the vehicle immediately
and switch off the engine.
Check the engine oil level and top off as
required. If the oil level is correct,
please contact the nearest BMW
center.
Do not continue driving, as the
engine could sustain serious
damage from inadequate lubrication.

<



Brake hydraulic system

l

The brake fluid level is too low.
Before driving further, be sure to
read the notes on pages 104 and 126.

lamp for Canadian models.

At higher speeds, it may occur
that the lower air pressure which
is created in the passenger compart-
ment will cause the top or the rear
window to flutter. Increase the air
supply via the ventilation controls so
that a low pressure draft does not occur
in the vehicle.<
