Keys1 The Key Memory functions are stored
in the remote-control key, refer to
page 49
You can mark individual keys for
subsequent identification by apply-
ingh the colored 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 steering
lock every time you drive.
For this reason, if you have a master
key that is not in regular use, use that
key approximately once every year
while driving for an extended period to
charge the battery. Also refer to
page 33.< 520de142
2 Spare key for storage in a safe place,
such as in your wallet. This master
key is not intended for continuous
use
3 Door and ignition key
The lock for the glove compartment
cannot be operated with this key.
This is recommended for valet
parking, etc.
There is a key case available for using
your master key on a regular basis.
Replacement keysReplacement keys are available exclu-
sively through your BMW center. Your
BMW center is obligated to ensure that
a person requesting a key is authorized
to do so, since the keys are an integral
element of the security system (refer to
"Electronic vehicle immobilizer" in the
following columns).
If possible, take all of the master
keys that belong to the vehicle
with you when you pick up your
replacement key.
Whenever you receive a new replace-
ment key, turn it once to position 2 in
the ignition lock (ignition switched on)
and then back, so that the electronic
vehicle immobilizer can initialize the
new key.<

Opening and closing Ð from the outsideUsing the remote control Remote control offers you optimal
convenience in using your vehicle's
locking system while also providing
three exclusive supplementary features:
>Interior lamp activation, refer to
page 34.
With this function, you can also
"search for" your vehicle Ð if, for
example, it is parked in an under-
ground garage.
>Opening the luggage compartment
lid, refer to page 35
>Panic mode, refer to page 35.
In case of danger, you can trigger an
alarm.
The anti-theft system is also deacti-
vated/activated simultaneously with the
unlocking or locking of the vehicle, and
the alarm system is disarmed/armed,
and the interior lamps are turned on/off.
Master keysKeys with remote control are master
keys. Refer to page 30.
You can have different confirma-
tion signals programmed into the
system to verify that the vehicle has
been locked correctly.<
Because passengers or animals
remaining in the vehicle could lock
the doors from the inside, you should
always remove the key and take it with
you to ensure that you remain able to
unlock the vehicle from the outside at
all times.<520de010
Master keys that are used repeat-
edly are always ready for opera-
tion since the battery in the key is
charged automatically in the steering
lock every time you drive.
If it is no longer possible to unlock the
vehicle via the remote control, the
battery is discharged. Use this key
while driving for an extended period in
order to charge the battery. Refer also
to page 30.
To prevent unauthorized use of the
remote control, surrender only the door
and ignition key 3 or the spare key 2
(refer to page 30) when leaving the
vehicle for valet parking, for example.
In the event of a system malfunction,
please contact your BMW center. You
can also obtain replacement keys
there.<

Vehicle storage
If the vehicle is to be stored for
more than three months, ensure
that the following service operations
are carried out first.<
Preparations for storageHave your BMW center perform the
following procedures:
1. Clean and apply a rust proofing
agent or other treatment to the
engine, engine compartment, under-
carriage, axles and major compo-
nents in accordance with approved
repair procedures. Wash the vehicle,
clean the interior and treat painted
and chromed parts. Clean the
weather-stripping around the hood,
luggage compartment and doors
2. Change engine oil and oil filter at
operating temperature. As an addi-
tional corrosion protection measure,
an anticorrosive agent can be added
to the engine in accordance with the
manufacturer's instructions
3. Check the coolant level and concen-
tration and top off if necessary
4. Check the fluid level of the wind-
shield washer fluid reservoir; top off
if necessary
5. Fill the fuel tank completely to
prevent the formation of condensa-
tion
6. Increase the tire inflation pressure to
51 psi (350 kPa).Before parking the vehicle1. Dry the parking brake and footbrake
by brake applications to prevent the
brake discs and drums from
corroding
2. Park the vehicle in a covered, dry,
and well-ventilated area. Place the
transmission in first gear or, if neces-
sary, chock the wheels to prevent the
vehicle from rolling. Do not engage
the parking brake
3. Remove the battery, charge it
completely and store it in a cool (but
frost-free) room
4. Remove the hardtop and store it
separately, refer to page 96
5. Close the convertible top.
During storageRecharge a battery that has been taken
out of the vehicle every six months. If it
is not recharged, it will not be service-
able. Every time the battery is
discharged, especially over extended
periods, its service life is reduced.Removing the vehicle from
storageRecharge the battery if the "Magic Eye"
turns black, refer to page 138.
Then have Inspection I performed by
your BMW center, including a brake
fluid replacement, if necessary. Refer to
the Service and Warranty Information
Booklet (US models) or the Warranty
and Service Guide Booklet (Canadian
models).

Lamps and bulbs The lamps and bulbs make essential
contributions to the safety of your
vehicle. Therefore, comply fully with the
following instructions during bulb
replacement. If you are not familiar with
any of the procedures, consult your
BMW center.
Do not touch the glass portion of a
new bulb with your bare hands
since even small amounts of impurities
burn into the surface and reduce the
service life of the bulb. Use a clean
cloth, paper napkin, or a similar mate-
rial, or hold the bulb by its metallic
base.<
A replacement bulb set is available from
your BMW center.
Whenever working on the elec-
trical system, switch off the elec-
trical accessory you are working on or
disconnect the cable from the negative
terminal of the battery. Failure to do this
could result in short circuits.
To prevent injuries and damage,
comply with any instructions provided
by the bulb manufacturer.<
When cleaning the headlamps,
please observe the following:
>Do not wipe dry (scratches). Never
use abrasives or strong solvents to
clean the covers
>Remove dirt and contamination (such
as insects) by soaking with BMW Car
Shampoo and then rinsing with plenty
of water
>Always use a deicer spray to remove
accumulated ice and snow Ð never
use a scraper.<
Xenon lamps

The main headlamps for your BMW
Z8 roadster have been designed using
xenon-light technology. The service life
of these bulbs is very long and the
probability of a failure is very low,
provided that they are not switched on
and off an unusual number of times.
Should a lamp ever fail, however,
please contact your BMW center for
assistance.
The xenon-light unit operates at
extremely high voltages; contact
with the unit's electrical components
can be fatal. We therefore urge you to
refer all service and repairs, including
bulb changes, to qualified professional
technicians.<
Neon lampsThe front turn signal indicators (side
marker lamps), the rear turn signal indi-
cators, the rear and brake lamps, as
well as the high-mounted brake lamp
are of neon-light technology. The
service life for these lamps is very high
and the likelihood of failure very
minimal.
Should a lamp ever fail, however,
please contact your BMW center for
assistance.
