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, please have the opera-
tions performed by your BMW center.<
To openPull the release handle and open the
hood.
It is not possible to drive off using
SMG II 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.<

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 89 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.
Battery
Battery posts, terminals, and
related accessories contain lead
and lead compounds. Wash hands after
handling.<
MaintenanceThe battery is completely maintenance-
free. That means that the original bat-
tery acid will normally last for the ser-
vice life of the battery under moderate
climate conditions.
Please consult your BMW center
whenever you have any questions
concerning the battery. Since the bat-
tery is absolutely maintenance-free, the
following statements are for your infor-
mation only.<
Never disconnect the battery
when the engine is running; the
ensuing voltage surge would seriously
damage the vehicle's onboard elec-
tronic systems. when the engine is not running. Use the
connections provided in the engine
compartment. For information on the
connections, see Jump-starting,
page 145.
Return used batteries to a recy-
cling point or your BMW center.
Maintain the battery in an upright posi-
tion for transport and storage. Secure
the battery against tilting in transit.<
