For your own safety
Maintenance and repair
Advanced technology, e. g. the use of
modern materials and high-performance
electronics, requires specially adapted mainte-
nance and repair methods. Therefore, only have
corresponding work on your BMW carried out
by a BMW center or a workshop that works
according to BMW repair procedures with cor-
respondingly trained personnel. If work is car-
ried out improperly there is a danger of conse-
quential damage and the related safety risks.<
California Proposition 65 warning
California laws require us to state the following
warning:
Engine exhaust and a wide variety of
automobile components and parts,
including components found in the interior fur-
nishings in a vehicle, 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 CA to
cause cancer and birth defects or other repro-
ductive harm.
Battery posts, terminals and related accesso-
ries contain lead and lead compounds. Batter-
ies also contain other chemicals known to the
State of California to cause cancer. Wash your
hands after handling.
Used engine oil contains chemicals that have
caused cancer in laboratory animals. Always
protect your skin by washing thoroughly with
soap and water.<
Parts and accessories
For your own safety, use parts and acces-
sories 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 performance when installed on your

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 different periods of time.
If a malfunction occurs in one of the monitored
systems, the corresponding light does not go
out after the engine has started, or it lights up
again while the vehicle is in motion. You can find
more information about each system on the
specified pages.

The key set
1Master keys with remote control
Each key is powered by an extended-life
battery that is charged automatically in the
ignition lock as you drive. For this reason,
use every master key at least twice a year to
keep its battery charged. Depending on
which master key is recognized when the
vehicle is unlocked, different settings are
called up and carried out in the vehicle, refer
to Key Memory on page31.
2Spare key
For storage in a safe place, e.g. in your wal-
let.
This key is not intended for constant use.
New keys
You can obtain new keys, whether as additional
keys or replacement keys, at your BMW center.
Central locking system
The concept
The central locking system is ready for opera-
tion 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 back-
rests
>opened manual convertible top.
The central locking system can be operated
>from outside using the remote control or via
the driver's door lock
>from inside via the central locking system
button.
If it is operated from inside, the fuel filler door
will not be locked. Refer to page18.
The anti-theft system is automatically activated
whenever you activate the central locking sys-
tem from outside the vehicle. It prevents the
doors from being unlocked with the lock but-
tons or release handles. The alarm system is
also armed.
In the event of a sufficiently severe accident, the
central locking system unlocks automatically. In
addition, the hazard warning flashers and inte-
rior lamps come on.
Opening and closing:
from outside
With the remote control
Whenever you unlock or lock the vehicle, you
simultaneously deactivate/activate the anti-
theft system, disarm/arm the alarm system and
switch the interior lamps on/off.
You will find more information about the alarm
system on page25.
Since persons or animals in the vehicle
could lock the doors from the inside,
always take the vehicle keys with you so that
the vehicle can be opened again from the out-
side at any time.<

by pulling the switch upward.
If you wish, you can have this special fea-
ture activated/deactivated.<
After the ignition has been switched off
You can still open or close the windows for up to
15 minutes, as long as no one opens any of the
doors.
When leaving the vehicle, always remove
the ignition key from the lock and remem-
ber to close the doors, since children could oth-
erwise operate the windows and injure them-
selves, etc.<
For convenience operation via the remote con-
trol or the door lock, refer to page17 or18,
respectively.
Pressure-sensitive finger guard
system
If the closing force exceeds a certain value while
a window is being raised, the system will
respond by stopping the window and then
retracting it a small distance.Despite the finger guard system, make
sure that the windows can close without
obstruction, since in some cases, e.g. with thin
objects, it is not guaranteed that the closing
operation will be interrupted.
The finger guard system function is restricted
when the switch is pulled and held beyond the
pressure point.<
After a power supply interruption
After a power supply interruption, for instance
after disconnecting the battery, the pressure-
sensitive finger guard system must be reinitial-
ized:
Ensure that the doors and convertible top are
closed before initializing. Perform the following
procedure twice for each window:
>Open and close the window completely
>With the window closed, keep pulling the
switch upward for approx. 1 second.
Manual convertible top
The fabric top offers perfect protection against
the weather and it can be opened easily and
quickly by one person alone.
Here are a few tips so that you get the most out
of your BMW:
>It is advisable to close the convertible top
when the vehicle is parked. The closed con-
vertible top not only protects the passenger
compartment from unforeseeable damage
from the weather, but also provides a cer-
tain degree of theft protection
>In addition, only keep valuables in the
locked luggage compartment, even with the
convertible top closed
>When the convertible top is open, the cen-
tral locking system also locks the release
button for the convertible top. The convert-
ible top cannot be operated. This provides
better theft protection for valuables stored
in the luggage compartment
>Never mount a roof-mounted luggage rack
system on the convertible top.

Opening and closing
22 the top not only guards the passenger com-
partment from unforeseeable damage from
the weather, but also affords a degree of
protection against theft. In addition, only
keep valuables in the locked luggage com-
partment, even with the convertible top
closed
>Never mount a roof-mounted luggage rack
system on the convertible top
>To avoid damage, do not operate the con-
vertible top at temperatures below 147/
–106.
To avoid permanent damage from mois-
ture, never store the convertible top while
it is wet.
Driving when the opening or closing process
has not been completed can cause vehicle
damage or personal injury.
Do not lay objects on the convertible top, since
they could fall off when the convertible top is
operated and cause damage or injuries.
Do not reach into the convertible top mecha-
nism during opening and closing. Keep children
away from the moving parts of the convertible
top during operation.<
If possible, only operate the convertible
top with the vehicle stopped, as other-
wise the process may be interrupted.
If you set the convertible top in motion while the
vehicle is stationary and then have to start sud-
denly, for instance at a traffic light, you can still
complete the procedure by driving as slowly as
possible and again holding the corresponding
button pressed.
At higher speeds, a vacuum effect in the pas-
senger compartment can cause the convertible
top to begin fluttering. Increase the air supply
so that a low pressure draft does not occur in
the vehicle.<
Opening and closing
1To close
2To open
If at all possible, only operate the convert-
ible top if the engine is running. This
saves unnecessary battery wear.
Before closing the convertible top, remove any
objects from the windshield frame that could
keep the convertible top from closing prop-
erly.<
Ignition key in position 1 or higher.
With the vehicle standing.
1.Read and comply with the preceding safety
precautions
2.Make sure that the convertible top com-
partment panel in the luggage compart-
ment is lowered; refer to page19. Other-
wise the convertible top cannot be opened
3.Ensure that the luggage compartment lid is
closed
4.Press and hold the corresponding button
for convertible top operation.
If the convertible top should halt right before the
closing phase is completed, press against the
front part of the convertible top frame from the
outside to help the closing process along. Keep
pressing the button while doing so until the top
starts up again on its own.
Indicator lamps
>The red indicator lamp in the button 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 in the button
flashes after the button has been released,

Clothes hooks
Clothes hooks1 are located on the wind deflec-
tor panels in the rollover bars.
Do not hang heavy objects on the hooks.
If you do, they could endanger the pas-
sengers, for example during braking or evasive
maneuvers.<
Storage
For storage, e.g. to achieve a better view to the
rear when the convertible top is closed, there
are two brackets on the inside of the luggage
compartment lid.
Insert the wind deflector into the brackets.
Make sure that the wind deflector cannot
be damaged by objects in the luggage
compartment.<
Alarm system*
The concept
The vehicle alarm system responds:
>When a door, the hood or the luggage com-
partment lid is opened
>When attempts are made to start the vehi-
cle
>When there are movements in the vehicle
interior: interior motion sensor, refer to
page26
>To alterations in the vehicle tilt, e.g. as
would occur during attempts to steal the
wheels or tow the vehicle
>To interruption of battery voltage.
The alarm produced by the system in the 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 flashers for
approx. five minutes.
Arming and disarming the alarm
system
When the vehicle is locked or unlocked either
with the remote control or at the driver's door
lock, the alarm system is simultaneously armed
or disarmed.
The hazard warning flashers blink once when
the alarm system has been properly armed.
You can have different acknowledgment
signals set to confirm arming and disarm-
ing.<
You can still open the luggage compartment
even when the system is armed by pressing the
button on the remote control, refer to
page17. When it is closed, the lid is once again
secured.
Manual operation of the luggage com-
partment lid triggers the alarm. Refer to
page18.<

2 Ignition switched on
All systems are operational.
3 Starting engine
Engine
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 discharging, always
deactivate electrical devices that are not in use.
Switch the ignition off when the vehicle is not
being driven.
Do not leave the engine running in
enclosed spaces. Otherwise, inhaling the
hazardous exhaust gases could lead to uncon-
sciousness and death. The exhaust gases con-
tain carbon monoxide, an odorless and color-
less, but highly toxic gas.
Do not leave the vehicle unattended with the
engine running. An unattended vehicle with a
running engine poses a safety hazard.
Before you leave the vehicle with the engine
running, place the engine in idle first or engage
the P position and apply the parking brake. If
you fail to do this, the vehicle could move.<
Starting the engine
Do not press the accelerator pedal while start-
ing the engine.
Do not let the engine warm up in idling position.
Instead, begin to drive at moderate engine
speeds.
Vehicles with manual transmission:
Step on the clutch when starting the vehi-
cle. A lockout prevents the engine from starting
if the clutch is not depressed.<
Do not end the starting procedure too early, but
do not continue it for more than 20 seconds.
Release the ignition key immediately when the
engine starts.
If the engine fails to start on the first attempt,
e.g. if it is very hot or cold:
Press the accelerator pedal halfway down.
Cold starts at very low temperatures, below
approx. +57/–156, and at high altitudes,
above 3,300 ft/1,000 m:

Lamps and bulbs
The lamps and bulbs make essential contribu-
tions to the safety of your vehicle. Therefore,
comply fully with the following instructions dur-
ing bulb replacement. If you are not familiar with
the procedures, BMW recommends that you
have your BMW center carry out the work.
Do not touch the glass portion of a new
bulb with your bare hands since even
small amounts of impurities burn in to the sur-
face and reduce the service life of the bulb. Use
a clean cloth, paper napkin or a similar material,
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 disconnect the cable from the
negative terminal of the battery. Failure to
observe this precaution could result in short cir-
cuits.
To prevent injuries and damage, always comply
with any instructions provided by the bulb man-
ufacturer.<
Accessing the headlamps
Protective cover in the wheel well
To gain access to the headlamp covers, turn the
front wheels in the required direction.

Replacement procedures
94 Please contact a BMW center in case of a mal-
function.
License plate lamps
5 watt bulb
1.Push out the lamp with a suitable object and
remove it
2.Replace the bulb.
Snap the lamp back into place.
Light-emitting diodes LEDs
Control elements, display units and other inte-
rior equipment in your vehicle use a light-emit-
ting diode behind a cover as a light source.
These light-emitting diodes are similar to con-
ventional lasers.
Do not remove the covers, and do not
look directly at the unfiltered light for sev-
eral hours. Otherwise, it can lead to retinal irrita-
tion of the eye.<
Changing a wheel
Run Flat tires
Your BMW is equipped with Run Flat tires.
Therefore, the wheel no longer has to be
changed immediately in the event of a loss in
inflation pressure.
Run Flat tires are labeled on the sidewall with a
circular symbol containing the letters RSC.
Refer to page82.
BMW recommends that you consult your BMW
center if you wish to replace the tires of your
B MW , o r change from summe r to winter tire s o r
vice versa.
Your BMW center knows how to work with Run Flat tires and is equipped with the necessary
special tools.
When mounting or replacing summer
tires with winter tires, or vice versa, use
only Run Flat tires since no spare wheel is avail-
able in the event of a flat.<
Jacking points
The jacking points are located at the positions
indicated in the illustration.
Your BMW center can provide you with a
suitable jack as an accessory.<
Vehicle battery
Maintenance
The battery is completely maintenance-free.
This means that the original electrolyte will nor-
mally last for the service life of the battery under
moderate climatic conditions. Your BMW cen-
ter will be happy to advise you if you have any
questions concerning the battery.
Indicator lamp
The indicator lamp lights up:
The battery is no longer being charged.
The alternator drive belt is defective or
there is a malfunction in the charging circuit of
the alternator. Please contact the nearest BMW
center.
If the drive belt is defective, pull over and
switch off the engine immediately to pre-
vent overheating and serious engine damage.
If the onboard supply voltage drops to a very
low level, increased steering effort may also be
necessary.<
