Clothes hooks
Clothes hooks1 are located on the wind deflec-
tor panels in the rollover bars.
Do not hang heavy objects on the hooks.
If you do, they could endanger the pas-
sengers, for example during braking or evasive
maneuvers.<
Storage
For storage, e.g. to achieve a better view to the
rear when the convertible top is closed, there
are two brackets on the inside of the luggage
compartment lid.
Insert the wind deflector into the brackets.
Make sure that the wind deflector cannot
be damaged by objects in the luggage
compartment.<
Alarm system*
The concept
The vehicle alarm system responds:
>When a door, the hood or the luggage com-
partment lid is opened
>When attempts are made to start the vehi-
cle
>When there are movements in the vehicle
interior: interior motion sensor, refer to
page26
>To alterations in the vehicle tilt, e.g. as
would occur during attempts to steal the
wheels or tow the vehicle
>To interruption of battery voltage.
The alarm produced by the system in the event
of unauthorized vehicle entry and attempted
theft depends on the country version:
>Sounding of an acoustical alarm for
30 seconds
>Activation of the hazard warning flashers for
approx. five minutes.
Arming and disarming the alarm
system
When the vehicle is locked or unlocked either
with the remote control or at the driver's door
lock, the alarm system is simultaneously armed
or disarmed.
The hazard warning flashers blink once when
the alarm system has been properly armed.
You can have different acknowledgment
signals set to confirm arming and disarm-
ing.<
You can still open the luggage compartment
even when the system is armed by pressing the
button on the remote control, refer to
page17. When it is closed, the lid is once again
secured.
Manual operation of the luggage com-
partment lid triggers the alarm. Refer to
page18.<

Lamps and bulbs
The lamps and bulbs make essential contribu-
tions to the safety of your vehicle. Therefore,
comply fully with the following instructions dur-
ing bulb replacement. If you are not familiar with
the procedures, BMW recommends that you
have your BMW center carry out the work.
Do not touch the glass portion of a new
bulb with your bare hands since even
small amounts of impurities burn in to the sur-
face and reduce the service life of the bulb. Use
a clean cloth, paper napkin or a similar material,
or hold the bulb by its metallic base.<
A replacement bulb set is available from your
BMW center.
Before working on the electrical system,
switch off the electrical accessory you are
working on or disconnect the cable from the
negative terminal of the battery. Failure to
observe this precaution could result in short cir-
cuits.
To prevent injuries and damage, always comply
with any instructions provided by the bulb man-
ufacturer.<
Accessing the headlamps
Protective cover in the wheel well
To gain access to the headlamp covers, turn the
front wheels in the required direction.

Vehicles with automatic transmission
Selector lever in position N.
Do not exceed a towing speed of 45 mph /
70 km/h or a towing distance of 90 miles/
150 km. Otherwise, the automatic transmission
could be damaged.<
Vehicles with sequential manual
gearbox SMG
To push or tow the vehicle, turn on the ignition
and move the selector lever to position N, then
turn the ignition off again.
Towing methods
In some countries, it is not permitted to tow the
vehicle with a tow bar or tow rope on public
roads.
Familiarize yourself with the applicable towing
regulations for the country in which you are
driving.
With a tow bar
The towing vehicle must not be lighter
than the vehicle being towed; otherwise,
vehicle handling can no longer be controlled.<
The towing eyelets of both vehicles should be
on the same side. If the tow bar can only be
used in a diagonal position, please note the fol-
lowing:
>Clearance is restricted while you are driving
around corners
>The inclination of the tow bar produces late-
ral force.
Only attach the tow bar to the towing eye-
lets. Other parts of the vehicle could oth-
erwise be damaged.<
With a tow rope
When the towing vehicle is driving off, make
sure that the tow rope is taut.
Use nylon ropes or straps for towing
because they prevent sudden jerking
movements. Attach tow ropes only to the tow-
ing eyelet. Other parts of the vehicle could oth-
erwise be damaged.<
With a tow truck
Have the BMW transported by a tow truck with
a lift sling, or on a flatbed.
Do not lift the vehicle by the towing eye-
let, or by parts of the body or chassis.
Otherwise damage could result.<
Tow-starting
Do not tow-start vehicles with automatic
transmission.
Jump-starting, refer to page97.<
Only tow-start vehicles with catalytic conver-
ters if the engine is cold. It is better to have the
vehicle jump-started, refer to page97.
1.Turn on the hazard warning flashers; com-
ply with national regulations
2.Turn the ignition key to position 2
3.Engage the 3rd gear. For vehicles with
SMG, refer to following column
4.Have the vehicle towed with the clutch
pedal completely depressed and then
slowly release the clutch pedal. After the
engine has started, immediately depress
the clutch pedal again completely
5.Pull over at a suitable location, remove the
tow bar or tow rope, and turn on the hazard
warning flashers
6.Have the vehicle checked.
