KickdownYou can achieve maximum road perfor-
mance using kickdown.
Depress the accelerator pedal past the
increased resistance point at the full-
throttle position.
M/S manual operation and Sport
programWhen you move the selector lever from
the D position to the left into the M/S
range, the sport program is activated,
indicated by the letters SD in the instru-
ment cluster. The M/S mode is recom-
mended for performance-oriented driv-
ing. Steptronic enters the manual
selection mode and executes the
desired shift whenever you tap the
selector lever in the direction indicated
by + or –.
This mode allows you to execute
upshifts manually by tapping the lever
toward +, while downshifts are selected
by tapping in the – direction. The dis-
plays M1 through M5 appear in the
instrument cluster.
The transmission will only execute
upshifts and downshifts that will result
in an appropriate combination of vehi-
cle speed and engine rpm. For
instance, downshifts that would result
in excessive engine speed are not exe-
cuted. The desired, then the actual
gear, briefly appear in the instrument
cluster.
Whenever you want to use automatic
again, just move the selector lever
toward the right to position D.
Shifting from M/S to the selector lever
positions P, R and N is possible only by
going through D.
To accelerate quickly in the man-
ual mode for maneuvers such as
passing another vehicle, shift down
manually or employ the kickdown
mode.<
Shifting from M/S to the selector lever
positions P, R and N is possible only by
going through D.

5. Use the magnetic holder to fasten
the cover panel to the back wall, then
pull out the ski bag.
Securing cargoAfter loading, secure the ski bag and its
contents. To do so, tighten the retaining
strap at the tensioning buckle.
Be sure to secure the ski bag in
this way, as it could otherwise
injure occupants, for example during
braking or evasive maneuvers.
Be sure that the skis are clean before
loading them into the bag. Be careful to
avoid damage from sharp edges.<
Stowing the ski bagTo store the ski bag, perform the steps
for loading in reverse sequence.
When reattaching the center
piece, guide both bars into the
guide and press the center piece back
into place. Secure the safety belts in
their holders again.<

Securing cargo>For small, light items, use the rubber-
lined, non-skid side of the floor mat
or secure using the luggage compart-
ment net* or elastic straps
>For large, heavy pieces, see your
BMW center for load-securing
devices*. Four anchorages located in
the luggage compartment can be
used for fastening these load-secur-
ing devices.
Read and comply with the information
enclosed with the load-securing
devices.
Always position and secure loads
correctly. If you do not, the load
can endanger the passengers during
braking or evasive maneuvers.
Do not exceed the approved gross
vehicle weight or the approved axle
loads, refer to page 172, otherwise the
vehicle's operating safety is no longer
assured and the vehicle will not be in
compliance with the certification regu-
lations.
Do not stow heavy or hard objects in
the passenger compartment without
securing them. Otherwise they could be
thrown around during braking and eva-
sive maneuvers and could endanger the
passengers.<

Roof-mounted luggage rack for the hardtop*A special roof-rack system is available
as an optional extra for your BMW.
Please observe the precautions
included with the installation instruc-
tions.AnchoragesAccess to the anchorages:
To fold up the covers, please use the
tool provided with the roof-rack system.Loading and driving notesRoof-mounted luggage racks raise the
center of gravity of the vehicle when
they are loaded. For this reason, they
exercise a major effect on the vehicle's
handling and steering response.
You should therefore always remember
not to exceed the approved roof load
capacity, the approved gross vehicle
weight or the maximum axle loads
when loading the rack. These weights
are listed under Technical data on
page 172.
Make sure that the load is not too bulky,
and attempt to distribute it evenly.
Always load the heaviest pieces first so
that they are at the bottom. Make sure
that no objects will be in the way when
the luggage compartment lid is opening
or closing.
Secure the roof-mounted luggage cor-
rectly and securely to prevent it from
shifting or being lost during driving.
Drive smoothly and avoid sudden
acceleration or braking. Do not corner
at high speeds.
The roof-mounted luggage rack and the
roof load increase the aerodynamic
resistance: increased fuel consumption
and additional stress on the vehicle's
body are the result.

4. Open the two locking levers at the
front of the hardtop. Press on the
buttons to do so. The levers will
release slightly. Open the levers as
far as possible
5. Before installing, first flip down the
cover panels 2 that are located
underneath the left and right inte-
rior lamps. To do this, press on the
slight bump on cover panel 2.
There is a holder in the cover panel
to securely store the trim pieces
that have been removed. Pull the
adapter 3 out of the holder, clip the
trim piece into the bottom and rein-
sert the adapter
6. Open the red locking levers as far
as the stop will allow, see arrow 4
7. Position the hardtop onto the sup-
port brackets with the help of a
second person. Be sure to put the
mountings exactly into the proper
brackets
Lift the hardtop carefully. Be
extremely careful not to shift the
seals. Seals that have been shifted out
of place or actually pulled out cause
leaks.<
8. In the back, close the red locking
levers by turning to the inside as far
as the stop located behind the trim
will allow. Flip the cover panels
back into place
9. To lock the hardtop in the front,
close the front locking levers until
you hear them engage
10. Check the seal between the wind-
shield frame and the hardtop on
both the left and right sides. If it is
folded or bent out of place, you
should smooth it back into position
by hand to ensure secure and reli-
able sealing.RemovalFollow the same procedure as when
installing, just reverse the steps.

HoodTo releasePull the lever located under the left-
hand side of the instrument panel.
Do not attempt to service your
vehicle if you do not have the
required technical background. If you
are not familiar with the regulations to
be observed, have your vehicle ser-
viced only by a BMW center or a shop
that works according to BMW require-
ments with the appropriately trained
personnel. Work that is improperly car-
ried out could result in consequential
damage and pose safety hazards.<
To openPull the release handle and open the
hood.
To closeAllow the hood to fall from a height of
about 1 ft/30 cm so that it audibly
engages.
To avoid injuries, be sure that the
travel path of the hood is clear
when it is closed, following the same
safety precautions used in all closing
procedures.
If you notice while driving that the hood
is not completely closed, stop immedi-
ately and close it securely.<

Do not lie under the vehicle or start the
engine when the vehicle is supported
by the jack. There is otherwise a risk of
fatal injury.<
Your BMW is equipped with a space-
saver spare tire designed for temporary
use in maintaining the vehicle's mobility
in an emergency.
To remove the space-saver spare
tire, lift the floor panel in the lug-
gage compartment completely out,
refer to page 35.<
