After an alarm has been triggered, the indicator
lamp will flash continuously.
Tilt alarm sensor
The inclination of the vehicle is monitored. The
alarm system reacts e.g. to attempts to steal a
wheel or tow the vehicle.
Interior motion sensor*
Coupe
All windows must be closed in order for the inte-
rior motion sensor to function optimally.
Roadster
The system monitors the footwells and the
seating areas of the driver and passenger. Even
when the convertible top is open, the alarm sys-
tem including the interior motion sensor is
armed. Objects falling into the vehicle, e.g.
leaves, can trigger unintentional alarms, refer to
Avoiding unintentional alarms.
Avoiding unintentional alarms
The tilt alarm sensor and interior motion sensor
can be deactivated at the same time. In this way
you can avoid unintentional alarms, e.g. in the
following situations:
>In duplex garages
>When transporting the vehicle on car-carry-
ing trains, by ship or on a trailer
>When animals are to remain in the vehicle
Switching off tilt alarm sensor and
interior motion sensor
>Press the button on the remote
control twice in a row.
The indicator lamp lights up briefly and then
flashes continuously. The tilt alarm sensor and
the interior motion sensor are deactivated until
the vehicle is again unlocked and locked.

Roadster: fully automatic
convertible top*
The fully automatic convertible top combines
assured protection against the elements with
simple and easy handling.
Here are a few tips so that you get the most out
of your BMW:
>It is advisable to close the convertible top
when the vehicle is parked. When closed,
the top not only guards the passenger com-
partment from unforeseeable damage from
the weather, but also affords a degree of
protection against theft. Valuables, how-
ever, should only be kept in the locked
cargo bay, even when the convertible top is
closed.
>Never mount a roof-mounted luggage rack
system on the convertible top.
Do not operate the convertible top at tem-
peratures below 147/–106, otherwise
damage could result.
Never keep a wet convertible top in the convert-
ible top compartment for longer than one day,
otherwise the moisture could cause damage.
Do not lay objects on the convertible top, other-
wise they could fall off when the convertible top
is operated and cause damage or injuries.
Driving while the convertible top is not com-
pletely open or closed can cause vehicle dam-
age or personal injury.
Do not reach into the convertible top mecha-
nism during opening and closing. Keep children
away from the convertible top's range of move-
ment.
For safety reasons, whenever possible operate
the convertible top when the vehicle is station-
ary.<
If a convertible top operation has not yet
been completed as you start to drive off,
at a traffic light for example, you can continue
the procedure at moderate speed:
To do so, press and hold the corresponding button again.
At higher speeds, a vacuum effect in the pas-
senger compartment can cause the convertible
top to begin fluttering. Use the air conditioning
or automatic climate control to increase the air
flow rate and thus prevent a partial vacuum in
the vehicle.<
Before opening and closing
>Read and comply with the preceding safety
precautions.
>Make sure that the convertible top com-
partment panel in the cargo bay has been
folded down; refer to page23. Otherwise
the convertible top cannot be opened.
>Ensure that the luggage compartment lid/
tailgate is closed.
Opening and closing
With the key in ignition position 1 or higher,
refer to page40, and while the vehicle is sta-
tionary:
If at all possible, operate the convertible
top only with the engine running. This
saves unnecessary battery wear.
Before closing the convertible top, remove any
objects from the windshield frame that other-
wise could prevent the convertible top from
closing properly.<
1Closing
2Opening
The side windows will move down slightly
when you press the button for operating
the convertible top.
After the opening or closing operation, the win-
dows will move back up if you press the button
for more than 2 seconds after the LED has gone

Adjustments
Safe seating position
For relaxed driving with as little fatigue as pos-
sible, you should select a seating position that
reflects your personal requirements. In combi-
nation with the safety belts, the head restraints
and the airbags, the seating position has a
major influence on your safety in the event of an
accident. To ensure that the vehicle's safety
systems provide you with optimal protection,
we request that you direct your careful attention
to the following section.
For supplementary information on transporting
children refer to page36.
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.
Never allow any objects, individuals or animals
to obstruct the areas between passengers and
airbags.
Never use the front airbag's cover as a storage
tray or support for objects of any kind. Ensure
that the passenger is correctly seated, e.g. does
not prop feet or legs against the dashboard.
Otherwise, leg injury could result if the knee air-
bag and front airbag suddenly deployed.
Make sure that the passenger does not lean his
or her head against the side airbag, otherwise
serious injuries could result if the airbags sud-
denly deployed.<
Even when all these guidelines are observed,
the risk of injury as a result of contact with the
airbags cannot entirely be ruled out in some sit-
uations. In sensitive individuals, the ignition and
inflation noise may induce a mild hearing loss
that is temporary in most cases.
For airbag locations and additional information
on airbags, refer to page56.
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 page32.
Safety belt
Make sure every occupant fastens his or her
safety belt. As supplemental restraint devices,
the airbags are designed to enhance the effec-
tiveness of the safety belts, and not to replace
them.
Your vehicle offers two sitting positions, 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 against the hips and does not press against
the abdomen. The safety belt must never rest
against the throat, rub against sharp edges,
pass over hard or fragile objects or be pinched.
Fasten the safety belt around your body snugly,
ma king sure tha t it is pulled taut across your lap
and shoulder and that it is not twisted; other-
wise, the belt can slide over the hips in the event
of a frontal collision and injure your abdomen.
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 page33.
Seats
Before adjusting your seat, always
observe the following precautions
Never try to adjust your seat while driving.
Otherwise, the seat could respond with
unexpected movement, and the ensuing loss of

Deactivating
Use the key to turn the key switch to the OFF
position.
The passenger airbags are deactivated in this
position. The airbags for the driver remain
active.
Reactivate the passenger airbags as soon
as a child-restraint system is no longer
installed on the passenger seat; otherwise they
may not deploy as intended in the event of an
accident.<
Reactivating

passenger airbags are deactivated.
>The indicator lamp is not lit when the pas-
senger airbags are activated.
When the seat is empty, the passenger
airbags are always deactivated. The indi-
cator lamp is not lit.<
Installing child-restraint
systems
Before installing a child-restraint system
on the passenger seat, make sure that the
front and side airbags for the passenger are
deactivated, otherwise there is an increased
risk of injury if the airbags deploy. Observe the child-restraint system manufacturer's instruc-
tions for selecting, installing and using child-
restraint systems. Otherwise the protective
effect may be diminished.<
Child seat security
The passenger's safety belt can be prevented
from being pulled out in order to fasten child-
restraint systems.
To lock the safety belt
1.Secure the child-restraint system with the
belt.
2.Pull the belt strap all the way out.

Adding engine oil
Do not add the maximum amount of 1 US quart/
1 liter of engine oil until the warning lamp lights
up in the instrument cluster, refer to page92, or
until the oil level monitor shows "+1.0".
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 warnings on
the containers. Otherwise, health hazards may
result.<
Oil change
Have your oil changed only by a BMW center or
a workshop that works according to BMW
requirements with the appropriately trained
personnel.
Approved engine oils
The quality of the engine oil is extremely impor-
tant for the function and life of an engine. BMW
continuously approves specific oils after con-
firming their suitability for use in its vehicles
with extensive testing.
Only use approved BMW High Performance
Synthetic Oil.
If BMW High Performance Synthetic Oil is not
available, you can add small quantities of other
synthetic oils in between oil changes. Only use
oils with the API SH specification or higher.
Your BMW center will be glad to answer
any questions regarding BMW High Per-
formance Synthetic Oil or other approved syn-
thetic oils. 1-800-831-1117 or visit the website
www.bmwusa.com to obtain this information.
Do not use any oil additives, as they could
cause engine damage under some cir-
cumstances.<
Viscosity classes
Viscosity is a measure of an oil's flow rating and
is categorized in SAE classes.
Selecting the appropriate SAE class depends
on the regional climatic conditions in which you
normally drive your BMW.
Approved oils belong to the 5W-40 and
5W-30 classes.<
These oils can be used for driving at all outside
temperatures.
Coolant
Warning lamp
The warning lamp lights up:
The coolant level is too low. Top up the
coolant as soon as possible.
Do not open the cooling system when the
engine is hot. If you do, escaping coolant
can cause burns.<
Coolant consists of water and coolant additives.
Not all commercially available additives are suit-
able for your BMW. Your BMW center knows
which additives are appropriate.
Only use approved additives, otherwise
the engine could be damaged. The addi-
tives are hazardous to health.<
Comply with the appropriate environ-
mental protection regulations when dis-
posing of coolant additives.<
Checking the coolant level
1.The engine must be at ambient tempera-
ture.
2.Turn the cap of the expansion tank a little
counterclockwise to allow any accumulated
