Indicator lamp displays
>The indicator lamp below the interior rear-
view mirror flashes continuously: the sys-
tem is armed.
>The indicator lamp flashes after locking:
door(s) or luggage compartment lid are not
completely closed. Even if you do not close
the alerted area, the system begins to mon-
itor the remaining areas, and the indicator
lamp flashes continuously after approx.
10 seconds. However, the interior motion
sensor is not activated.
>The indicator lamp goes out after unlocking:
no manipulation or attempted intrusions
have been detected in the period since the
system was armed.
>After unlocking, the indicator lamp flashes
until the key is inserted into the ignition
lock, but will not do so for longer than
roughly 5 minutes: an attempted entry has
been detected in the period since the sys-
tem was armed.
Tilt alarm sensor and interior motion
sensor
Tilt alarm sensor
Monitors the inclination of the vehicle. The
alarm system reacts, for example, if someone
attempts to steal the wheels or tow the vehicle.
Interior motion sensor
Coupe:
In order for the interior motion sensor to func-
tion properly, the windows and glass sunroof
*
must be completely closed.Convertible:
Monitors the interior up to the height of the seat
cushions. This means that the alarm system,
including the interior motion sensor, is armed
even if the convertible top is open. Falling
objects, e.g. leaves, can trigger false alarms,
refer to Avoiding unintentional alarms.
Avoiding unintentional alarms
The tilt alarm sensor and interior motion sensor
may be switched off at the same time. This pre-
vents unintentional alarms, e.g. in the following
situations:
>In stacking garages
>When transporting on car-carrying trains
>When animals are to remain in the vehicle
Switching off the tilt alarm sensor and
interior motion sensor
Press the button on the remote control
once again directly after locking.
The indicator lamp lights up briefly and then
flashes continuously. The tilt alarm sensor and
the interior motion sensor are switched off until
the vehicle is unlocked and locked again.
Windows
To prevent injuries, exercise care when
closing the windows and keep them in
your field of vision until they are shut.
When leaving the vehicle, always remove the
ignition key and close the doors to prevent chil-
dren from operating the power windows and
injuring themselves.<

On the front passenger side as well, do not tilt
the backrest too far toward the rear. Failure to
observe this precaution can prevent the belt
from providing effective protection against
injury, as the passenger could slide under the
belt in an accident.
Make sure that the footwell behind the driver's
and front passenger's seat is empty and unob-
structed. If you fail to do so, any persons or
objects behind the seat could be injured or
damaged by a rearward movement of the
seat.<
Also observe the instructions regarding dam-
age to the safety belt on page49.
Convertible: with the wind deflector fitted,
do not incline the front seat backrests too
far backward if the seat is to be moved back to
the end position, as otherwise the wind deflec-
tor will be damaged.<

Transporting children safely

Transporting children safely
The right place for children
Children always in the rear
Accident research shows that the safest place
for children in a vehicle is in the rear seat.
Older children should be tightly secured with a
safety belt, after they have outgrown a booster
seat that is appropriate for their age, height and
weight.
Child-restraint system in the rear
Children under 13 years of age and chil-
dren less than 5 ft/150 cm tall should
always ride in the rear and the restraint systems
should be secured with the vehicle's safety
belts.<
Younger children should be secured in an
appropriate forward-facing child-restraint sys-
tem that has first been properly secured. We
strongly urge you to carefully read and comply
with the instructions for installation and use
provided by the child-restraint's manufacturer
whenever you use such a device.
All rear sitting positions in your vehicle meet the
recommendations of SAE J1819, an industry-
recommended practice for securing child-
restraint systems in motor vehicles.
Exception for front passenger seat
Should it become necessary to use
a child-restraint system on the front pas-
senger seat, the airbags on the passenger's
side must be deactivated. Deactivating the front
passenger airbag is only possible on the Coupe.
Your BMW center will be glad to advise you.<
Never install a rearward-facing child-
restraint system in the front passenger
seat of this vehicle if the passenger airbag is not
deactivated. If you do so, the child could be
severely injured when the airbag is triggered.
Your vehicle is equipped with an airbag supple-
mental restraint system for the front passenger.
Because the backrest on any rearward-facing child-restraint system – of the kind designed for
infants under 1 year and 20 Ibs./9 kg – would be
within the airbag's deployment range, you
should never mount such a system in the front
passenger seat, since the impact of the airbag
against the child restraint's backrest could lead
to serious or fatal injuries.<
Installing child-restraint
systems
Before installing any child-restraint system or
child seat, read the following:
Observe the child-restraint system man-
ufacturer's instructions for installation
and use. Otherwise the degree of protection
can be reduced.
After an accident, have all parts of the child-
restraint system and of the relevant vehicle
safety belt system checked by a BMW center
and replaced if necessary.<
Commercially-available child-restraint systems
are designed to be secured with a lap belt or
with the lap belt portion of a combination lap/
shoulder belt. Improperly or inadequately
installed restraint systems can increase the risk
of injury to children. Always read and follow the
instructions that come with the system.
Child seat security
All of the rear belt retractors and the front pas-
senger's safety belt can be locked for mounting
and securing child-restraint systems.

Things to know about active cruise control
As with conventional cruise control sys-
tems, active cruise control in no way
diminishes or substitutes for the driver's own
personal responsibility, alertness and aware-
ness in adjusting speed, braking or otherwise
controlling the vehicle. The driver should
decide when to use the system on the basis of
road, traffic, visibility, and weather conditions.
Active cruise control is intended for use on
highway-type roadways where traffic is moving
relatively smoothly. Do not use this system in
city driving; heavy traffic such as during rush
hour; on curvy, winding roads, slippery roads or
roads with sharp curves such as highway off-
ramps; during inclement weather such as snow,
strong rain or fog; or when entering inter-
changes, service/parking areas or toll booths.
It is also important to regulate your vehicle's
speed and distance setting within applicable
legal limits. Always be ready to take action or
apply the brakes if necessary, especially when
the system is actively following a vehicle in front
of you.<
Always remember that the range and abil-
ity of the system does have physical limi-
tations. It will not apply the brakes or decelerate
your vehicle when there is a slow-moving vehi-
cle, stopped vehicle or stationary object ahead
of you, as for example, at a traffic light or when
approaching a parked vehicle. Also, the system
does not react to oncoming traffic, pedestrians
or other types of potential traffic such as a rider
on horseback. It is also possible that the system
may not detect smaller moving objects such as
motorcycles or bicycles. Be especially alert
when encountering any of these situations as
the system will neither automatically brake, nor
provide a warning to you. Also, be aware that every decrease in the distance setting allows
your vehicle to come closer to a vehicle in front
of you and requires a heightened amount of
alertness.<
If your vehicle is actively following a vehicle in
front of you and the vehicle ahead speeds up or
the lane ahead becomes clear, then your vehi-
cle will accelerate to the speed you have
selected. Be aware that changing to a clear,
unobstructed lane will also result in your vehicle
accelerating.
Be certain to deactivate the system when
you pull into an exit lane for a highway off-
ramp.<
Also, vehicles traveling in a staggered manner
on a highway may cause a delay in the system's
reaction to a vehicle in front of you or may cause
the system to react to a vehicle actually in the
lane next to you. Always be ready to take action
or apply the brakes if necessary.
Active cruise control can only decelerate the
vehicle to approx. 20 mph/30 km/h. If the sys-
tem reduces vehicle speed below 20 mph/
30 km/h or if DSC/ABS is engaged while driving,
the system will automatically deactivate.
Remember, the system cannot stop your
vehicle. In addition, the system is deacti-
vated whenever the driver applies the vehicle
brakes, shifts the transmission to neutral/N, or
deactivates DSC. After any deactivation, the
system will no longer automatically activate the
vehicle brakes, which means the driver must
intervene and resume manual braking. You
should then reactivate the system only when
you are fully aware of the prior speed and dis-
tance settings.<

sive maneuvers.<

Under the hood
174
Under the hood
Never attempt to perform any service or
repair operations on your vehicle without
the required, professional technical training. If
you are unfamiliar with the specifications to be
observed, only have work carried out on your
vehicle by a BMW center or a workshop which
works with personnel trained in accordance
with BMW specifications. Otherwise there is a
danger of damage and associated safety risks if
this work is performed improperly.<
Hood
Releasing
Pull the lever located under the left side of the
instrument panel.
Opening
Press the release handle and open the hood.
Closing
Close the hood from a height of approx. 16 in/
40 cm with momentum. It must be clearly heard
to engage.
Make sure that the closing path of the
