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
vehicle. BMW warrants these parts to be free from
defects in material and workmanship.
BMW will not accept any liability for damage
resulting from installation of parts and accesso-
ries not approved by BMW.
BMW cannot test every product made by other
manufacturers to verify if it can be used on a
BMW safely and without risk to either the vehi-
cle, its operation, or its occupants.
Original BMW Parts, BMW Accessories and
other products approved by BMW, together
with professional advice on using these items,
are available from all BMW retailers.
Installation and operation of non-BMW
approved accessories such as alarms, radios,
amplifiers, radar detectors, wheels, suspension
components, brake dust shields, telephones,
including operation of any portable cellular
phone from within the vehicle without using an
externally mounted antenna, or transceiver
equipment, e.g. C.B., walkie-talkie, ham radio or
similar, may cause extensive damage to the
vehicle, compromise its safety, interfere with
the vehicle's electrical system or affect the
validity of the BMW Limited Warranty. See your
BMW center for additional information.
Do not use key or remote control to lock doors
or trunk with anyone inside the vehicle. Refer to
the Owner's Manual for more details.<
Maintenance, replacement or repair of
the emission control devices and sys-
tems may be performed by any automotive
repair establishment or individual using any cer-
tified automotive part.<

Opening and closing

Opening and closing
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.<
To unlock
Press the button.

Replacement procedures
Onboard tool kit
The onboard tool kit is stored in a tool pouch. It
is located in the luggage compartment beneath
the floor panel.
Windshield wiper blades
1.Swich off the ignition
2.Fold the wiper arm completely out from the
windshield
3.Place the wiper blade in a position at right
angles to the wiper arm
4.Press the locking spring
5.Fold the wiper blade down and unhook it
toward the windshield
6.Pull the wiper blade past the wiper arm
toward the top
7.Insert a new wiper blade and apply pressure

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.<
