5. Before installing, first flip the cover
panels that are located underneath
the left and right interior lamps
down. To do this, press on the
slight bump on the cover panel.
There is a holder in the cover panel
to securely store the trim pieces
that have been removed – see
arrow 1
6. Open the red release levers as far
as the stop will allow – see arrow 2
7. Position the hardtop onto the sup-
ports with the help of a second
person. Be sure to put the mount-
ings exactly into the proper brack-
ets
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,
keep pressing on the front locking
levers until you hear them engage
10. Check the rubber weather-strip-
ping between the windshield 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 reliable
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. Failure
to work in an informed, professional
manner when servicing components
and materials constitutes a safety haz-
ard for vehicle occupants and other
road users. If you are not familiar with
the guidelines, BMW recommends that
you have the operations performed by
your BMW center.<
To openPull the release handle and open the
hood.
It is not possible to drive off using
SMG Drivelogic when the hood is
open.<
To closePull the hood downwards and allow the
hood to fall from a minimum height of
1 ft/30 cm so that it audibly engages.
Check for proper locking by pulling on
the hood at the left and right above the
headlamps.
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.<

Even if the tire fails to hold the
pressure, you should still carry out
Step 3 before proceeding to drive the
vehicle again, refer to Distributing the
sealant for more information. Then
repeat Steps 1 through 3.
The use of the M Mobility system may
be ineffective if the damaged area in
the tire is larger than approx. 1/8 in /
4 mm. Please consult the nearest BMW
center if the tire cannot be temporarily
repaired with the M Mobility system.<
3. Unscrew the hose from the valve and
stow the M Mobility system in the
luggage compartment. Screw the
dust cap onto the valve again.
Do not exceed the maximum
speed limit described below, oth-
erwise it could lead to accidents.<
When you start driving again, do not
exceed the permissible maximum
speed of 45 mph / 80 km/h.
You will find corresponding
instructions for using the
M Mobility system on the device.
Replace the defective tire as soon as
possible and have the new wheel bal-
anced. Reinitialize the Flat Tire Monitor,
and refer to page 88 for further informa-
tion. Have the M Mobility system
refilled. Contact your BMW center for
this.<
Protect valve stems against dirt using
screw-on dust caps. Dirty valve stems
frequently lead to slow pressure loss.

related accessories contain lead
and lead compounds. Wash hands after
handling.<
