For your own safety

Use unleaded gasoline only. Fuels
containing up to 10% ethanol or
other oxygenates with up to 2.8% oxy-
gen by weight (that is, 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 (volatility,
composition, additives, etc.) among ga-
solines 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 con-
ditions, such as high ambient tempera-
ture and high altitude.
Should you encounter driveability pro-
blems that you suspect could be rela-
ted 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
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 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
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 ac-
cessories) may cause extensive da-
mage to the vehicle, compromise its
safety, interfere with the vehicle's elec-
trical system, or affect the validity of the
BMW Limited Warranty. Visit your BMW
center for additional information.

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

Indicator and warning lampsTechnology that monitors itselfMany of the systems of your BMW
monitor themselves automatically, both
during engine starts and while you are
driving. Indicator and warning lamps
that are identified by "l" are tested for
proper functioning whenever the igni-
tion 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 below.
Red: stop immediately
Battery charge current l
The battery is no longer being
charged. There is a malfunction
of the alternator V-belt or in the charg-
ing circuit of the alternator. Please con-
tact the nearest BMW center.
If the ribbed V-belt is defective, do
not continue driving. The engine
could be damaged due to overheating.
If the ribbed V-belt is defective, in-
creased steering effort is also re-
quired.<
Engine oil pressure l
Comes on while the engine is
running and the "STOP!ENGINE
OILPRESS" message appears in the
Check Control: stop vehicle immedi-
ately and switch off engine. Check level
of oil in engine, top up as required. If oil
level is correct: please contact the
nearest BMW center.
Do not continue driving. The en-
gine could be damaged because
of inadequate lubrication.<
Tire Pressure Control (RDC)
* l
In addition, there is an acousti-
cal warning signal: a tire failure
has occurred. Reduce vehicle speed
immediately and stop the vehicle. Avoid
hard brake applications. Do not over-
steer. For additional information: refer
to page 103.
Parking brake

Alarm systemThe conceptThe vehicle alarm system responds:
>When a door, the hood or the lug-
gage compartment lid/tailgate is
opened.
>To movement inside the vehicle
(interior motion sensor).
>To variations in the vehicle tilt sensor
such as occur during attempts to
steal the wheels or tow the vehicle.
>To interruption of battery voltage.
The system responds to unauthorized
vehicle entry and attempted theft by
simultaneously activating the following:
>Sounding an acoustical alarm for
30 seconds.
>The hazard warning flashers are
activated for approx. five minutes.
>The high beams flash on and off in
the same rhythm.
To arm and disarm the
alarm systemWhen the vehicle is locked or unlocked
with the key or the remote control, the
alarm system is also simultaneously
armed or disarmed.
The interior motion sensor is activated
approx. 30 seconds after you have fin-
ished locking the car.
The system indicates that it has been
correctly armed by switching on the
hazard flashers for a single cycle and by
emitting an acoustical signal.
You can have different acknowl-
edgment signals set to confirm
arming and disarming.<
When the system is armed, you can still
gain access to the luggage compart-
ment lid/tailgate by pressing button 3
on the remote control (refer to page 41).
When you close the luggage compart-
ment lid/tailgate, it locks again.
Indicator lamp displays>The indicator lamp below the interior
rearview mirror flashes continuously:
the system is armed.
>The indicator lamp flashes during
arming: door(s), the hood or luggage
compartment lid/tailgate are not
completely closed. Even if you do not
close the alerted area, the system
begins to monitor the remaining ar-
eas, and the indicator lamp flashes
continuously after 10 seconds. How-
ever, the interior motion sensor is not
activated.
>If the indicator lamp goes out when
the system is disarmed: no manipula-
tion or attempted intrusions have
been detected in the period since
the system was armed.390de020

Electric power windowsOpen and close windowsFrom ignition key position 1:
>Depress the rocker switch until you
feel resistance:
The window continues moving for as
long as you maintain pressure on the
switch.
>Press the rocker switch beyond the
resistance point:
The window moves automatically.
Press the switch a second time to
stop the window.390de055
After the ignition has been switched off:
>You can still operate the windows as
long as neither of the front doors has
been opened. To open the window,
press the switch beyond the resis-
tance point.
Remove the key from the ignition
when you leave the vehicle, so
that children cannot operate the power
windows and possibly injure them-
selves.<
For the convenience mode via the door
lock or the remote control, refer to
pages 38 or 40.Safety featureA contact strip is integrated into the
inner side of each of the upper window
frame sections. If pressure is exerted
against this contact strip while a
window is being raised, the system
will respond by stopping the window
and then retracting it a small distance.
Despite this safety feature, be
extremely careful that the closing
path of the window is not obstructed
whenever it is closed. Otherwise, an
object might not touch the contact strip
in some situations (very thin objects, for
instance).
You can override this safety feature by
pressing the switch beyond the resis-
tance point and holding it.
Because the power windows are sealed
at high pressure to prevent wind noise
when closed, a powerful motor is
required for efficient closing. When
closing the windows, always be sure
that they are not obstructed in any way.
Unsupervised use of these systems can
result in serious personal injury.
Remove the ignition key to deactivate
the electric power windows whenever
you leave the car. Never leave the keys
in the vehicle with unsupervised chil-
dren.
Never place anything that could
obstruct the driver's vision on or next
to the windows.<
