switch.
>Press the switch beyond the resistance
point:
All windows open automatically. Press the

ment.
>Pull the switch:
All windows close as long as you pull the

After switching off the ignition
When the remote control is removed or the igni-
tion is switched off, you can still operate the
windows for approx. 1 minute as long as no
door is opened.
Convenient operation
For information on Convenient operation via the
remote control or the door lock, refer to page27
or30. For information on Convenient closing
with Comfort Access, refer to Locking on
page28.
Pinch protection system
If the closing force exceeds a specific value as a
window closes, the closing action is interrupted
and the window reopens slightly.
Despite the pinch protection system
check and clear the window's travel path
prior to closing it; otherwise, the safety system
might fail to detect certain kinds of obstruc-
tions, such as thin objects, and the window
would continue closing.
Do not install any accessories that might inter-fere with window movement. Otherwise, the
pinch protection system could be impaired.
Convertible: the rear windows are not equipped
with pinch protection. Therefore, watch them
closely when closing to avoid personal injury.<
Closing without pinch protection
If there is an external danger, or if ice on the win-
dows, etc., prevents you from closing the win-
dows normally, proceed as follows:
1.Pull the switch past the resistance point and
hold it there. Pinch protection is limited and
the window reopens slightly if the closing
force exceeds a certain value.
2.Pull the switch again past the resistance
point within approx. 4 seconds and hold it
there. The window closes without pinch
protection.
Coupe: glass roof*, electric
To prevent injuries, watch the glass roof
while closing it.
Take the remote control with you when you
leave the car; otherwise, children could operate
the roof and possibly injure themselves.<
Raising
Press the switch.
>The closed glass roof is raised and the slid-
ing visor opens slightly.
>The open glass roof automatically travels
into the raised position. The sliding visor
remains completely open.

* supplied with the
onboard vehicle tool kit, refer to page223,
into the opening provided. Move the glass
roof in the desired direction.
6.Reinstall the control unit and reattach the

Convertible: retractable
hardtop
The retractable hardtop combines reliable
weather protection with simple and convenient
operation.
The following tips will enhance your driving
pleasure in your Convertible:
>It is advisable that you close the retractable
hardtop when you park the vehicle. Not only
does the closed hardtop protect the vehicle
interior against unanticipated weather dam-
age, it also offers theft protection. However,
even when the hardtop is closed, valuables
should only be stored in the locked cargo
area.
>Do not attach roof rack systems to the
retractable hardtop, and in particular do not
attach magnetic racks.
>Do not attach rack systems to the trunk lid,
and in particular do not attach magnetic
racks.
>When the retractable hardtop is operated,
the trunk lid swings back and up. Before
operating the retractable hardtop, ensure
that there is enough clearance, e.g. when
parked in front of a wall.
>If you open the hardtop while it is wet, e.g.
after driving in the rain, water may drip into the cargo area. If necessary, remove items
from the cargo area beforehand to avoid
water stains or soiling.
Do not place any objects on the retract-
able hardtop or on the trunk lid; other-
wise, they could fall during movements of the
retractable hardtop and cause damage or injury.
Never move the retractable hardtop when the
rollover protection system is in the activated
position.
Driving when the hardtop is not fully opened or
closed may result in damage or injury.
Do not reach into the mechanism during the
opening or closing procedure. Keep children
away from the swiveling area of the retractable
hardtop.<
The retractable hardtop cannot be moved
at temperatures below + 147/–106. A
message appears on the Control Display.<
The retractable hardtop can only be
opened and closed when the vehicle is
stationary. To avoid causing damage, do not
drive off until the hardtop has stopped mov-
ing.<
Before opening and closing
>Comply with the safety precautions
described above.
>Ensure that the cargo area partition is
folded down and engaged on both sides,
refer to page110; otherwise, it will not be
possible to open the retractable hardtop.
>Do not place any objects next to or on the
cargo area partition and close the storage
compartment on the left side of the cargo
area.
>Do not exceed the maximum loading height
under the cargo area partition; refer to the
label in the cargo area showing a line indi-
cating the maximum height.
>Ensure that the trunk lid is closed.
>The vehicle should be parked on fairly level
ground. Excessive angle is indicated by a
lamp.

Adjustments
Sitting safely
The ideal sitting position can make a vital con-
tribution to relaxed, fatigue-free driving. In con-
junction with the safety belts, the head
restraints and the airbags, the seated position
has a major influence on your safety in the event
of an accident. To ensure that the safety sys-
tems operate with optimal efficiency, we
strongly urge you to observe the instructions
contained in the following section.
For additional information on transporting chil-
dren safely, refer to page52.
Airbags
Always maintain an adequate distance
between yourself and the airbags. Always
grip the steering wheel on the rim, with your
hands in the 3 o'clock and 9 o'clock positions,
to minimize the risk of injury to the hands or
arms in the event of the airbag being triggered
off.
No one and nothing should come between the
airbags and the seat occupant.
Do not use the cover of the front airbag on the
front passenger side as a storage area. Make
sure that the front passenger is sitting correctly,
e.g. not resting feet or legs on the dashboard;
otherwise, leg injuries can occur if the front air-
bag deploys.
Make sure that passengers keep their heads
away from the side airbag and do not lean
against the cover of the head airbag; otherwise,
serious injuries can result if the airbag
deploys.<
Even if you follow all the instructions, injuries
resulting from contact with airbags cannot be
fully excluded, depending on the circum-
stances. The ignition and inflation noise may
provoke a mild hearing loss in extremely sensi-
tive individuals. This effect is usually only tem-
porary.
For airbag locations and additional information
on airbags, refer to page90.
Head restraint
A correctly adjusted head restraint reduces the
risk of neck injury in the event of an accident.
Adjust the head restraint in such a way
that its center is at approx. ear level. Oth-
erwise, there is an increased risk of injury in the
event of an accident.<
Head restraints, refer to page44.
Safety belt
Before every drive, make sure that all occupants
wear their safety belts. Airbags complement the
safety belt as an additional safety device, but
they do not represent a substitute.
Your vehicle has four seats, each of which is
equipped with a safety belt.
Never allow more than one person to
wear a single safety belt. Never allow
infants or small children to ride in a passenger's
lap. Make sure that the belt in the lap area sits
low across the hips and does not press against
the abdomen.
The safety belt must not rest against the throat,
run across sharp edges, pass over hard or frag-
ile objects or be pinched. Fasten the safety belt
so that it sits as snugly as possible against the
lap and shoulder without being twisted. Other-
wise, the belt could slide over your hips and
injure your abdomen in the event of a frontal
collision.
Avoid wearing bulky clothing and regularly pull
the belt in the upper-body area taut; otherwise,
its restraining effect could be impaired.<
Safety belts, refer to page48.
Seats
Note before adjusting
Never attempt to adjust your seat while
the vehicle is moving. The seat could
respond with unexpected movement, and the
ensuing loss of vehicle control could lead to an

dren.
To install and use the LATCH child
restraint system, follow the operating and
safety instructions provided by the manufac-
turer of the system; otherwise, the protective
function of the seat may be compromised.<
Mounts for the lower LATCH anchors
Before installing the child seat, pull the belt out
of the area for the child restraint fixing system.
Ensure that both lower LATCH anchors
are correctly engaged and that the child

Too much oil will harm the engine.
Have the vehicle checked without
delay.<
>"Measurement inactive. Have this
checked."
Do not add engine oil. You can continue
your journey. Note the newly calculated dis-
tance remaining to the next oil service, refer
to page73. Have the system checked as
soon as possible.
Adding engine oil
Add up to 1 US quart/1 liter of engine oil only
after a corresponding message is shown on the
Control Display.
Add oil within the next 125 miles/200 km;
otherwise, the engine could be dam-
aged.<
Keep oils, greases, etc. out of the reach of
children and comply with the relevant
warnings on the containers. Otherwise, health
hazards may result.<
Oil change
Have oil changed only at your BMW center or at
a workshop that works according to BMW
repair procedures with correspondingly trained
personnel.
Oil types
Do not use oil additives as this could
result in engine damage.<
Specified engine oils
Your service center can advise you on which
engine oils have been approved by the manu-
facturer of your vehicle.The engine oil quality is critical for the life of the
engine.
Only use approved High Performance oil.
Approved oils belong to the following viscosity
classes: SAE 0W-40, SAE 0W-30, SAE 5W-40
and SAE 5W-30.
Alternative oil types
If the approved engine oils are not available, up
to 1 US quart/1 liter of another oil with the fol-
lowing specification may be used:
API SM or higher
Coolant
Do not add coolant to the cooling system
when the engine is hot. Escaping coolant
can cause burns.<
Coolant consists of half water and half additive.
Not all commercially available additives are suit-
able for your BMW. Ask your BMW center for
suitable additives.
Only use suitable additives; otherwise,
engine damage may result. Because
additives are harmful to your health, it is impor-
tant to follow the instructions on the contain-
ers.<
Comply with the appropriate environ-
mental protection regulations when dis-
posing of coolant additives.<
Checking coolant level
1.Do not open the engine hood before the
engine has cooled down.
2.Turn the cap of the expansion tank a little
counterclockwise to allow any accumulated
pressure to escape, then continue turning
to open.
3.The coolant level is correct if it is between
the maximum and minimum marks in the
