Remote control4. Press and hold down button 1 (see
illustration). Maintain pressure on
button 1 while rapidly pressing
button 2 three times in succession
within a period of 10 seconds
5. Release button 1. LED 3 flashes
slowly for a maximum of 10 seconds
6. The central locking system engages
and releases all lock mechanisms in
rapid succession to indicate that the
initialization procedure has been
successfully completed.
If the LED does not flash or if the
central locking system fails to respond,
the initialization procedure will have to
be repeated.
All additional master keys with remote
control for your vehicle (up to a
maximum of four units) must now be
initialized. Make sure that no more than
30 seconds is allowed to elapse
between the individual initialization
procedures. Repeat steps 4 and 5. The
central locking system will respond to
each initialization procedure as
descriped in step 6.
In the event of a system malfunction,
please contact your BMW center, who
can also provide you with replacement
keys.Turn each new master key into
ignition position 2 (ignition
switched on) and back again to allow
the electronic vehicle immobilizer (refer
to page 31) to recognize the new key.
To prevent unauthorized use of the
master key, surrender only the door and
ignition key 3 or the spare key 2 (refer
to page 30) for valet parking, for
instance.<

Safety measures in the event of a
flat tire or a wheel change:
Stop the vehicle on a firm, level surface
as far as possible from the flow of
traffic. Turn on the hazard warning
flashers.
Turn the steering wheel to the straight-
ahead position and engage the steering
lock, engage the parking brake and
shift into 1st or reverse gear (selector
lever in "Park" with automatic transmis-
sion).
All passengers should be outside the
vehicle and well away from your imme-
diate working area (for instance, behind
the guardrail).
If a warning triangle or portable hazard
warning lamp is available, set it up on
the roadside at an appropriate distance
from the rear of the vehicle. Comply
with all safety guidelines and regula-
tions.
Change the wheel only on a level, firm
surface which is not slippery. Avoid
jacking the vehicle on a soft or slippery
support surface (snow, ice, tiles, loose
gravel, etc.), since it could slide side-
ways.
Place the jack on a firm support
surface.
Do not place wooden blocks or similar
objects under the jack. If this is done,
the jack might not be able to reach its
full support capacity because of the
limited height.
Do not lie under the vehicle or start the
engine when the vehicle is supported
by the jack. This creates the risk of fatal
injury.<
What you will needThe illustration depicts an example of
the onboard tool kit of the Z3 coupe.
Other than the warning triangle, the
same tools are arranged somewhat
differently in the storage compartment
of the Z3 roadster.
In order to avoid rattling noises later,
note the position of the tools when you
remove them and return them to their
original position when you are through
using them.

luggage compartment.
The spare wheel is secured at two
mounting points.
Left-hand attachment point Ð arrow 1.
Right-hand attachment point Ð arrow 2.367de312
Right-hand attachment point:
Place the spark plug wrench on the
hexagon nut and, using the alignment
tool to assist you, loosen the hexagon
nut. Remove the hexagon nut and the
protective cap.
Place the hexagon nut in a secure
location.< 367de268
Left-hand attachment point:
Take the lifting handle from the tool kit,
lower it on the rope and fit it on the
hexagon nut. Hold the rope at the top
and unscrew the nut with the lifting
handle.367de269

Wheel changePull the lifting handle up until the spare
wheel tray is lifted slightly. At the same
time, compress the locking spring
(arrow). This releases the spare wheel
(weight: approx. 8.8 lbs/4 kg). The
spare wheel must then be held with the
lifting handle.
Using the lifting handle, lower the spare
wheel bracket with storage tray and
spare wheel and place it on the ground.
Do not put your feet beneath the
rear of the vehicle because the
spare wheel could fall as it is being
lowered.< 367de270
Pull the storage tray with the spare
wheel completely out of the spare
wheel bracket toward the rear.367de276
Lift the spare wheel at the front. Lay it
down toward the rear next to the
storage tray and with the valve facing
upward. Quickly unscrew the valve
extension from the valve of the spare
wheel. Unscrew the valve cap from the
storage tray and mount it on the spare
wheel.
When the valve extension is
screwed onto or off of the spare
wheel, you may hear a brief hissing as
air escapes.<
The procedure for removing the spare
wheel is also illustrated with picto-
graphs located on the floor mat of the
luggage compartment.367de277

Wheel change
The wheel with the flat tire cannot
be placed in the spare wheel
bracket in the place of the spare
wheel.<
There is a plastic bag in the onboard
tool kit. Put the flat tire and the storage
tray into this bag.
Do not reposition the storage tray
in the spare wheel bracket without
the spare wheel.<
Using the lifting handle, pull the spare
wheel bracket upward until the spring
retainer catches. Secure the bracket
with the hexagon nut Ð ensure that it is
tightened down correctly.
The spare wheel is returned to its orig-
inal position in the same manner as it is
removed, however in the reverse order.
When doing so, make sure that:
>The valve extension is mounted on
the spare wheel valve
>The storage tray is facing toward the
rear (see arrow) with the valve exten-
sion pointing to the inside left to
ensure that it is possible to check the
tire inflation pressure.367de271
Mount the spare wheel1. Secure the vehicle to prevent it from
rolling:
Place the wedge against the rear
surface of the front tire on the side
opposite the side being raised. If the
vehicle is parked on a downward
slope, place the wedge securely in
front of the tire. If the wheel must be
changed on a surface with a more
severe slope, take additional precau-
tions to secure the vehicle from
rolling
2. Wheels with full wheel covers
*:
reach into the ventilation openings
and pull the cover off
3. For wheels equipped with hub
covers
*: position a screwdriver in the
slot and pry the hub cover off
4. Loosen the lug bolts g a turn

Wheel change5. Position the jack on the vehicle:
>Plastic elements are mounted on
the vehicle floorpan for positioning
the jack. These positions (refer to
the arrows) are located approx.
16 in (40 cm) from the front wheel
opening and
10 in (25 cm) from the rear wheel
opening
>If necessary, remove snow, ice or
mud from the plastic elements
>Screw the jack arm up until the
jack just fits under the vehicle367de382
>Position the jack at the jacking
point closest to the flat tire so that
the jack base is vertically below
the jacking point and the entire
surface of the head of the jack will
move squarely into the recess of
the plastic element when the jack
is cranked
>Crank the jack until the wheel you
are changing is off of the ground.
6. Unscrew the lug bolts and remove
the wheel
7. Remove accumulations of mud or
dirt from the mounting surfaces of
the wheel and hub. Clean the lug
bolts367de065
8. Take the centering pin from the
vehicle tool kit. Insert the centering
pin together with the plastic cap
into one of the bolt sockets
9. Position the spare wheel and screw
at least two lug bolts into opposite
bolt sockets. Remove the centering
pin
10. Screw in the remaining lug bolts.
Tighten all the bolts down correctly
11. Lower the jack and remove it from
beneath the vehicle
12. Tighten the lug bolts in a diagonal
pattern367de066

Wheel change13. Wheels with full wheel covers:
Place the wheel cover with the
valve opening over the valve. Use
both hands to press the cover
securely onto the rim
14. Check and correct the inflation
pressure at the earliest opportunity.
Use only the full wheel cover
installed by the factory. Other
wheel covers may not fit securely. The
full wheel cover may not be installed on
the spare wheel because the cover
could be damaged.<
The jack is designed for changing
wheels only. Do not attempt to lift
a different vehicle model or any other
type of load with the jack. To do so
could lead to property damage or
personal injury.
To ensure continued safety, check the
tightness of the lug bolts at the earliest
opportunity (torque specification:
72 lbs ft [100 Nm]).<
If light-alloy wheels other than Original
BMW light-alloy wheels have been
mounted, it may be necessary to use
different lug bolts for those wheels.
Replace the defective tire as soon as
possible and have the new wheel/tire
balanced.
Driving with the spare wheelDrive cautiously and do not exceed a
speed of 50 mph (80 km/h).
Be aware that vehicle handling will be
altered. Slower brake response time,
longer braking distances and changed
steering characteristics may be antici-
pated when approaching limit condi-
tions.
Only one spare wheel may be
mounted at any time. Mount a
wheel and tire with the same size and
specifications as the others at the
earliest possible opportunity. Maintain
the specified tire inflation pressures,
refer to the table on page 27.<
