Indicator and warning lamps

Technology that monitors itself

Indicator and warning lamps that are
identified by

●

are tested for proper
functioning whenever the ignition key is
turned. They each light up once for dif-
ferent 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 in the follow-
ing section.

Red: stop immediately

Battery charge current

●

The battery is no longer being
charged. Indicates a defective
alternator drive belt or a problem with
the alternator's charge circuit. Please
contact the nearest BMW center.
If the drive belt is defective, stop
and switch off the engine immedi-
ately to prevent overheating and seri-
ous engine damage. If the drive belt is
defective, increased steering effort is
also required.

<

Engine oil pressure

●

Stop the vehicle immediately
and switch off the engine.
Check the engine oil level; top off as
required. If the oil level is correct:
please contact the nearest BMW cen-
ter.
Do not continue driving, as the
engine could sustain serious dam-
age from inadequate lubrication.

30Opening and closing
KeysThe key set1Master keys with remote control –
determine the functions of the Key
Memory, refer to page 69.
You can mark the individual keys for
subsequent identification by apply-
ing 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 ignition
lock as you drive.
For this reason, if you have master keys
that are not being used otherwise, use
those keys approximately once a year
while driving for an extended period to
charge the battery.<
2Spare master key – for storage in a
safe place, such as in your wallet.
This key is not intended for constant
use
3Door and ignition key – the locks for
the luggage compartment lid and the
glove compartment cannot be oper-
ated with this key. This is useful for
valet parking, for example
Central locking systemThe conceptThe central locking system engages
and releases the following locks at the
same time
>doors
>luggage compartment lid
>fuel filler door
>glove compartment.
The central locking system is ready for
operation whenever the driver's door is
closed.
The central locking system can be
operated
>from outside via the door lock as well
as via the remote control
>from inside by pressing a button.
The fuel filler door is not locked when
the central locking system is activated
from the inside, refer to page 34.
When the system is actuated from the
outside, the anti-theft system is also
activated. This prevents the doors from
being unlocked via the lock buttons or
the release handle. The alarm system is
also armed or disarmed.
The central locking system is automati-
cally deactivated in the event of an
accident. In addition, the hazard warn-
ing flashers and interior lamps come on.

Opening and closing – via the remote controlThe conceptThe remote control gives you an excep-
tionally convenient method for unlock-
ing and locking your vehicle. Further-
more, it provides two additional
functions:
>To switch on interior lamps, refer to
page 32.
With this function you can also
search for the vehicle when parked in
an underground garage, for instance
>To open the luggage compartment
lid, refer to page 32.
The luggage compartment lid will
open slightly, regardless of whether it
was previously locked or unlocked.
Whenever you unlock or lock the vehi-
cle, you simultaneously deactivate/acti-
vate the anti-theft system, disarm/arm
the alarm system and switch the interior
lamps on/off.
You can have a signal set to con-
firm that the vehicle's locks have
engaged securely.<
Master keys with remote control
Persons or animals inside the
vehicle may be able to lock the
doors from the inside. For this reason,
you should always take the vehicle keys
with you so that the vehicle can be
opened again from the outside at any
time.<
If it is no longer possible to lock
the vehicle via the remote control,
the battery is discharged. Use this key
while driving for an extended period in
order to recharge the battery.
To prevent unauthorized use of the
remote control, surrender only the
spare key or the door and ignition key
when leaving the vehicle for valet park-
ing, for example.
In the event of a system malfunction,
please contact your BMW center. You
can also obtain replacement keys
there.<

Before lowering the convertible
top, refer to page 41 or 46, always
check to ensure that the luggage com-
partment panel has returned to its origi-
nal position. Attempts to lower the top
with the panel folded up can lead to
vehicle damage.<
Alarm system*The conceptThe vehicle alarm system responds:
>When a door, the hood or the lug-
gage compartment lid is opened
>To movements inside the vehicle –
interior motion sensor
>To variations in the vehicle's tilt angle
such as those occurring during
attempts to steal the wheels or tow
the vehicle – tilt alarm sensor
>To interruption of battery voltage.
The system responds to unauthorized
vehicle entry and attempted theft by
simultaneously activating the following:
>The acoustic alarm sounds for
30 seconds
>The hazard warning flashers are acti-
vated for approx. five minutes
>The high beams flash on and off in
rhythm with the hazard warning flash-
ers.To arm and disarm the alarm
systemWhen the vehicle is locked or unlocked
via the driver's door lock or with the
remote control, the alarm system is also
simultaneously armed or disarmed.You can have different acknowl-
edgment signals set to confirm
arming and disarming.<
You can open the luggage compart-
ment lid when the system is armed by
pressing the remote control button,
refer to page 32. The lid is once again
secured when it is closed.

To avoid placing unnecessary loads on
the battery, you should avoid operating
the top when the engine is switched off.
1. Read and comply with the preceding
safety precautions
2. Before opening the convertible top,
ensure that the convertible top com-
partment panel is back down into its
original position, refer to page 37
3. Ensure that the luggage compart-
ment lid is closed
4. Maintain pressure on the corre-
sponding button for the convertible
top operation.
The red indicator lamp flashes when-
ever the convertible top mechanism
is in operation. It goes out when the
opening or closing process has been
completed.
If it continues flashing after the con-
trol button is released, the process
has not completed opening or clos-
ing. You can resume operation in the
desired direction by pressing the
button again.
If the yellow indicator lamp lights up
continuously with the button
pressed, the convertible top com-
partment panel has been raised and
the top cannot be moved, refer to
step 2.
The convertible top stops moving
immediately when the button is
released. You can resume operation in
the desired direction by pressing the
button again.<
While the convertible top is in
motion, the rear window will move
toward the passenger compartment. To
avoid possible pinching, the area
around the closing convertible top
should be clear.<
The side power windows are lowered a
small distance whenever the top is set
in motion by pressing the button and
after the opening or closing process is
completed, they will go back up, if you
keep holding the button down for more
than 2 seconds after the indicator lamp
has gone out.
The luggage compartment lid cannot be
opened while the convertible top is in
motion.
Do not close the side power win-
dows using the buttons if the con-
vertible top operation has been inter-
rupted.<
After having been stored for an
extended period of time in the
convertible top compartment, e.g. dur-
ing 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: If the
convertible top should halt just before

Do not actuate the starter for too
short a time, but do not actuate it
for more than approx. 20 seconds.
Release the ignition key immediately
when the engine starts.
Do not allow the engine to warm up by
leaving it running while the vehicle
remains stationary. Instead, drive off
immediately at a moderate engine
speed.<
If the engine does not start on the first
attempt – if it is very hot or cold, for
instance:
>Press the accelerator pedal halfway
down while engaging the starter.
Cold starts at extremely low tempera-
tures below approx. +57/–156 and at
altitudes over 3,300 ft/1,000 m:
>On the first start attempt, it may be
necessary to engage the starter for a
longer period – but no longer than
20 seconds
>Press the accelerator pedal halfway
down while engaging the starter.
Engine idle speed is controlled by the
engine computer system. Increased
speeds at start-up are normal and
should decrease as the engine warms
up. If engine speed does not decrease,
service is required.
To prevent the battery from discharg-
ing, always deactivate electrical
devices that are not in use. Switch the
ignition off when the vehicle is not
being driven.
Extended starting attempts, char-
acterized by excessively frequent
or long periods with the starter
engaged, can damage the catalytic
converter.<

141 Laws and regulations
California Proposition 65 warningCalifornia laws require us to state the
following warning:
Engine exhaust, some of its con-
stituents, and certain vehicle com-
ponents contain or emit chemicals
known to the State of California to
cause cancer and birth defects and
reproductive harm. In addition, certain
fluids contained in vehicles and certain
products of component wear contain or
emit chemicals known to the State of
California to cause cancer and birth
defects or other reproductive harm.
Battery posts, terminals and related
accessories contain lead and lead com-
pounds. Wash your hands after hand-
ling.
Used engine oil contains chemicals that
have caused cancer in laboratory ani-
mals. Always protect your skin by
washing thoroughly with soap and
water.<
OBD interface socketThe interface socket for onboard diag-
nostics is located on the left-hand side
of the driver's side, behind a specially
marked cover located beneath the
instrument panel. The cover has the let-
ters OBD on it.
This interface makes it possible to
access data on emissions-related com-
ponents using special equipment.
An illuminated indicator informs
you of the need for service, not
that you need to stop the vehi-
cle. However, the systems should be
checked by your BMW center at the
next opportunity.
If the indicator blinks or flashes, this
indicates a high level of engine misfire.
Reduce speed and contact the nearest
BMW center immediately. Severe

Lamps and bulbsThe lamps and bulbs make essential
contributions to the safety of your vehi-
cle. Therefore, comply fully with the fol-
lowing instructions during bulb replace-
ment. 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 in to 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.
Before working on the electrical
system, switch off the electrical
accessory you are working on or dis-
connect the cable from the negative
terminal of the battery. Failure to
observe this precaution could result in
short circuits.
To prevent injuries and damage, com-
ply with any instructions provided by
the bulb manufacturer.<

The H7 bulb is pressurized. There-
fore, wear safety glasses and pro-
tective gloves. Failure to comply with
this precaution could lead to injury if the
bulb is damaged.<
1. Turn the two release catches at the
front to the left – see arrow – to
remove the bulb holder
2. Remove and replace the bulb.
When cleaning the headlamps,
please follow the instructions in
the Caring for your vehicle brochure.<
Xenon lamps*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. If one of these bulbs should
nevertheless fail, it is possible to con-
tinue driving with great caution using
the fog lamps, provided local traffic
laws do not prohibit this.
Because of the extremely high
voltages involved, any work on the
xenon lighting system, including bulb-
changing, should be carried out by
technically qualified personnel only.
Otherwise, there is a risk of fatal
injury.<
