Indicator and warning lamps

Technology that monitors itself

Indicator and warning lamps identified
by "

l

" are tested for proper operation
whenever the ignition key is turned.
They each light up once for different
periods of time.
The indicator lamps signal defects in
monitored systems by either remaining
lit after the engine is started or by
coming on in the course of normal
vehicle operation. Refer to the following
section for detailed information on how
to respond to the various types of warn-
ings.

Red: stop immediately

Battery charge current
The battery is no longer being
charged. Indicates a defect in
the alternator drive belt or the charging
circuit. Please contact the nearest
BMW center.
Never attempt to continue driving
if the drive belt is defective: the
engine could overheat and sustain
serious damage. A broken or damaged
drive belt will also lead to a sudden
increase in steering effort.

<

Engine oil pressure

l

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

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.<

The automatic convertible topWeather protectionThe fabric convertible top combines
reliable protection from the elements
with simple, convenient operation. Here
are a few tips to ensure that you enjoy
your BMW Z8 roadster.
It is advisable to close the convertible
top when the vehicle is parked. The
closed convertible top not only protects
the passenger compartment from
unforeseeable damage from the
weather, it also provides a certain
degree of theft protection. Even if the
convertible top is closed, store your
valuables only in the locked luggage
compartment.
To prevent damage to its rear window,
avoid opening or closing the fabric top
unless the temperature is well above
freezing. Operate the convertible top only
when the vehicle is stationary,
otherwise the procedure will be inter-
rupted. Driving before the opening or
closing procedure has been properly
concluded can lead to damage or
injury.
Do not lay objects on the convertible
top, since they would fall off when the
convertible top is operated and cause
damage or injuries.
Make sure that no objects or people get
in the way while the convertible top is
opening or closing, so that no damage
or injuries occur.
The automatic operating procedure is
interrupted immediately if the switch
for actuating the top is released. The
procedure can be continued in the
desired direction by pressing this
switch.<
To openFrom ignition key position 1:
If at all possible, only operate the
convertible top if the engine is running
to avoid discharging the battery.
Press and hold the switch in the
"Open" (1) direction until the opening
procedure has been completed with the
convertible top being stored in the
convertible top compartment and the
indicator lamp on the instrument cluster
(refer to page 18) has gone out.
The side windows will lower slightly
when the convertible top is being
opened. To reclose the side windows,
maintain pressure on the switch after
the indicator lamp goes out. 520de055

minimal amount of power. In order to
avoid discharging the battery, remove
the key if the vehicle is to be parked for
an extended period of time.<

Starting the engine Before starting>Engage the parking brake
>Make sure that the transmission is in
neutral
>Depress the clutch pedal
>Turn ignition key to position 2.
Do not allow the engine to run in
enclosed areas. The exhaust
gases contain carbon monoxide, an
odorless and colorless, but highly toxic
gas. Breathing the exhaust gases poses
an extreme health risk, and can lead to
unconsciousness and death.
Do not leave the vehicle unattended
with the engine running. An unattended
vehicle with a running engine repre-
sents a potential safety hazard.<520de141
Do not press the accelerator pedal
while starting the engine (pressing the
starter button).
Do not actuate the starter button
for too short a time, but do not
keep it pressed for more than approx.
20 seconds.<
Do not allow the engine to warm up by
leaving it running while the vehicle
remains stationary. Instead, begin to
drive immediately at a moderate engine
speed.
Cold starts at very low temperatures,
from approx. +5 7 (Ð15 6) and at alti-
tudes above 3,300 ft (1,000 meters):
>On the first start attempt, engage the
starter for a longer period (approx.
10 seconds).
Engine idle speed is controlled by the
electronic engine-management system.
A fast idle immediately after starting is
normal and should decrease as the
engine warms up. If the idle does not
return to normal as the engine reaches
normal operating temperature, service
is required.
To prevent the battery from
discharging, always deactivate elec-
trical devices that are not in use. Switch
the ignition off when the vehicle is not
being driven.
