1 Master key with battery-powered
lamp (switch on by pressing the BMW
symbol).
2 Master key without lamp.
3 Spare key to be kept in a safe place
e. g. in your wallet. This key is not
intended for continuous use.
4 Door and ignition key
This key does not operate the locks
for the glove compartment and the
luggage compartment. This is useful
e. g. at a hotel.The electronic vehicle immobilization
unit increases the anti-theft protection
of your BMW Ð without additional
adjustment or activation of systems.
This electronic immobilization system is
designed to reduce the susceptibility of
the vehicle to theft by making it impos-
sible to start the engine using any
means other than the special keys fur-
nished with the vehicle.
The system features an electronic chip
integrated within the key as a supple-
ment to the conventional mechanical
locking system.
The lock mechanism itself is actually a
dual-function device, simultaneously
serving as a communications interface
designed to allow the car security sys-
tem to maintain a continuous stream of
variable, vehicle-specific signals with
the electronic circuitry in the key. The
ignition, the flow of fuel and the starter
are enabled only after the key has been
recognized as "authorized".
b
External force can damage the
electronic circuitry integrated in the key.
Such a key can no longer be used to
start the engine.c
Replacement of a keyReplacement keys are available exclu-
sively through your authorized BMW
Retailer, who is also under obligation to
request verification of vehicle owner-
ship before issuing a substitute key.
Your BMW Retailer can also cancel or
restore the electronic system authoriza-
tion for individual keys (e.g., if a key is
lost). A deactivated key can no longer
be used to start the engine.For US owners onlyThe transmitter and receiver units com-
ply with Part 15 of the FCC (Federal
Communication Commission) Regula-
tions. Operation is governed by the fol-
lowing:
FCC ID: LXBEWS
As defined in the regulations, such a
device is not to emit significant interfer-
ence and must also be shielded against
interference from external sources to
prevent unauthorized or inadvertent
activation.a
Any unauthorized modifications
or changes to these devices could void
the userÕs authority to operate this
equipment.c

Never use spot remover, paint thinner,
solvents, gasoline etc. to remove spots
from the convertible top and from the
rear window, as these substances
destroy the rubber seals and lead to
leaks. Use only BMW-approved clean-
ers.
In addition to the advantage of being
extremely flexible, the rear window also
has the disadvantage of having a rela-
tively soft surface. For this reason, only
clean the rear window with a soft, anti-
static cloth or with BMW Convertible
Rear Window Cleaner.
If you wash the vehicle frequently in
brush car washes, and in particular in
those with hard brushes, faint scratches
in the rear window may result. With the
window replacement system you can
replace a heavily scratched window at a
relatively low price. Please contact your
authorized BMW Retailer for additional
information. b
A full range of car-care products is
available from your BMW Retailer.c
a
Cleaning agents can contain sub-
stances that are dangerous or bad for
your health. Therefore always observe
the warnings and danger notices on the
package.
Open the doors or windows on your ve-
hicle when cleaning the interior.
Never clean your vehicle with solvents
or other materials not specifically in-
tended for this application.c
Hardtop:Please follow the instructions for car
care from page 131.If the vehicle is to be temporarily stored
for more than three months, have the
following maintenance performed by
your BMW Retailer:
1 Cleaning, preservation and retreat-
ment of the engine, engine compart-
ment, underbody, axles and
subassemblies in accordance with
the factory speciÞcations. Vehicle
washing with interior cleaning fol-
lowed by paint and chrome care.
Clean rubber seals of the hood, lug-
gage compartment lid and doors and
rub with either talcum powder or
glycerine oil.
2 Change engine oil and oil Þlter at
operating temperature. As an addi-
tional corrosion protection measure,
an anti-corrosive agent can be added
to the engine in accordance with the
manufacturer's instructions.
3 Check the coolant level and concen-
tration and top up if necessary.
4 Check the acid level in the battery
cells and add distilled water if neces-
sary.
5 Increase the tire inßation pressure to
50.9 psi (3.5 bar).
