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 workmanship. Field experience has indi-
cated significant 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 drivability, start-
ing and stalling problems especially under
certain environmental conditions, such as
high ambient temperature and high alti-
tude.
Should you encounter driveability prob-
lems 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 recommenda-
tions may result in unscheduled mainte-
nance.
Follow the relevant safety rules when you
are handling gasoline.<
Important safety information!
For your own safety, use 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 perfor-
mance when installed on your vehicle.
BMW warrants these parts to be free from
defects in material and workmanship.
BMW will not accept any liability for dam-
age 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 occu-
pants.Original BMW Parts, BMW Accessories
and other products approved by BMW,
together with professional advice on using
these items, are available 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
vehicle's electrical system or affect the
validity of the BMW Limited Warranty. See
your BMW center for additional information.
Do not use key or remote control to lock
doors or luggage compartment with any-
one inside the car. Refer to the Owner's
Manual for more details.<
Maintenance, replacement or repair
of the emission control devices and
systems may be performed by any automo-
tive repair establishment or individual using
any certified automotive part. This manual is supplemented by a Service
and Warranty Information Booklet for US
models or a Warranty and Service Guide
Booklet for Canadian models.
We recommend that you read this publica-
tion thoroughly.
Your BMW is covered by the following war-
ranties:
>New Vehicle Limited Warranty
>Rust Perforation Limited Warranty
>Federal Emissions System Defect

Keys
The key set
1Master keys with remote control –
determine the functions of the Key
Memory, refer to page 37.
You can mark individual keys for subse-
quent identification by applying the col-
ored decals that you received when
accepting delivery of your vehicle
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
with remote control that is otherwise
not used, use that key approximately
once a year while driving for an
extended period to charge the bat-
tery.<
2Spare key for storage in a safe place,
such as in your wallet.
This key does no open the lock of the
luggage compartment lid – useful for
valet parking, for example.
This key is not intended for constant
use
Central locking system
The concept
The central locking system is ready for
operation whenever the driver's door is closed. The system simultaneously
engages and releases the locks on the
>doors
>luggage compartment lid
>fuel filler door
>storage compartment between the
backrests
>opened manual convertible top.
The central locking system can be oper-
ated
>from outside using the remote control
or via the driver's door lock
>from inside via the central locking sys-
tem button.
If it is operated from inside, the fuel filler
door will not be locked. Refer to page 20.
The anti-theft system is automatically acti-
vated whenever you activate the central
locking system from outside the vehicle. It
prevents the doors from being unlocked
with the lock buttons or release handles.
The alarm system is also armed.
The central locking system unlocks auto-
matically in the event of an accident. In
addition, the hazard warning flashers and
interior lamps come on.
Remote control
The concept
The remote control provides two additional
functions for central locking.
>Switching on interior lamps. Refer to
page 19.
With this function, you can also search
for the vehicle when parked in an
underground garage, for instance
>Opening the luggage compartment lid
separately. Refer to page 19. The lug-
gage compartment lid will open slightly,
regardless of whether it was locked or
unlocked.

you simultaneously deactivate/activate
the anti-theft system, disarm/arm the alarm
system and switch the interior lamps on/

To avoid injuries, be sure that the
travel path of the luggage compart-
ment lid is clear when it is closed, following
the same precautions as with all closing

ditioner or automatic climate control to

Indicator lamps
>The red indicator lamp will light up while
the convertible top is in motion. It goes
out as soon as the opening or closing
operation has been completed
>If the red indicator lamp flashes after
the button has been released, then the
opening or closing operation has not
yet been completed.
The sequence can be continued in the
desired direction by pressing this but-
ton

continuously with the button pressed,
then the convertible top compartment
panel is raised and the convertible top

stored for an extended period of time
in the convertible top compartment – e.g. in
the winter months because the hardtop
was being used – you may have to support
the convertible top by hand when closing it
for the first time.<

been interrupted due to an electrical mal-
function, the convertible top will remain in
that position for 15 minutes. The procedure
can be resumed in the desired direction by
pressing the button. After that, the convert-
ible top can be moved again and, if it is an
emergency situation, you may have to help

event of unauthorized vehicle entry and
attempted theft depends on the country
version:
>Sounding of an acoustical alarm for
30 seconds
>Activation of the hazard warning flash-
ers for approx. five minutes.
Arming and disarming the alarm sys-
tem
When the vehicle is locked or unlocked
either via the driver's door lock or with the
remote control, the alarm system is simul-
taneously armed or disarmed.The hazard warning flashers blink once
