in the passenger compartment at a low
level when the convertible top is open, this
enabling pleasant driving even at higher

luggage compartment when it is not
needed.
Before fitting
1.Take the wind deflector from the pro-
tective sleeve

Adjustments
Sitting safely
The ideal sitting position can make a vital
contribution to relaxed, fatigue-free driving.
The sitting position also plays an important
role together with the safety belts and air-
bags in providing occupants with maximum
levels of passive safety in an accident. To
ensure that the safety systems operate with
optimal efficiency, we strongly urge you to
observe the instructions contained in the
following section.
For additional information on transporting
children safely, refer to page 51.
Sitting safely with airbags
Always maintain an adequate dis-
tance between yourself and the air-
bags. Always hold the steering wheel by
its rim with hands at the 9 o'clock and
3 o'clock positions, to minimize the risk of
injuries to your hands and arms in the event
of airbag deployment.
No one and nothing is to 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 sit-
ting correctly and does not rest feet or legs
on the instrument panel, otherwise leg inju-
ries can occur if the knee and front airbags
are triggered.
Never let an occupant's head rest near or
on a side airbag because the inflating air-
bag could cause a serious or fatal injury.<
Even if you adhere to all the instructions
injuries resulting from contact with airbags
cannot be fully excluded, depending on the
circumstances. The ignition and inflation
noise may provoke a mild – usually tempo-
rary – hearing loss in extremely sensitive
individuals.
For airbag locations and additional infor-
mation on airbags, refer to page 81.
Sitting safely with safety belts
Fasten your safety belt before starting any
trip. Airbags complement the safety belt as
an additional safety device, but they do not
represent a substitute.
Your vehicle has four seats that are all
equipped with a safety belt.
At all times, occupants should sit
upright and be properly restrained:
infants and small children in appropriate
child-restraint systems; larger children and
adults using the safety belts.
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.
Expectant mothers should always wear
their safety belts, taking care to position
the lap belt against the lower hips, where it
will not exert pressure against the abdomi-
nal area.
Do not route the belt across your neck, or
run it across sharp edges. Be sure that the
belt does not become caught or jammed.
Avoid twisting the belt while routing it firmly
across the hips and shoulder. Do not allow
the belt to rest against hard or fragile
objects. Otherwise, in the event of a frontal
impact, a loose lap belt could slide over
your hips, leading to abdominal injury.
Avoid wearing clothing that prevents the
belt from fitting properly and pull the lap
belt periodically to readjust the tension
across your shoulder in order to avoid a
reduction in the retention effect of the
safety belt.<
For instructions on operating safety belts,
refer to page 47.

Seats
Note before adjusting
Never attempt to adjust your seat
while operating the vehicle. The seat
could respond with unexpected move-
ment, and the ensuing loss of vehicle con-
trol could lead to an accident.
On the front passenger side as well, do not
tilt the backrest too far toward the rear
while driving. Failure to observe this pre-
caution 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 unobstructed. 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
damage to the safety belt on page 47.
Convertible: with the wind deflector
fitted, do not incline the front seat
backrests too far backwards if the seat is to
be moved back to the end position, as oth-
erwise the wind deflector will be dam-
aged.<

To ensure that the safety systems
continue to provide optimized protec-
tion, please observe the adjustment

If the safety belts are damaged or
stretched in an accident: have the
entire belt system, including the tensioning
mechanisms, replaced at your BMW cen-
ter. Have the belt anchorage points
inspected for damage at the same time.
Failure to observe this precaution may pre-
vent the safety belts from effectively pro-
viding optimal protection when needed.<

The system regulates the temperatures of
the seat cushion and backrest.
The temperature setting progresses one
step through its control sequence each
time you press the button.

Mirrors
Adjusting exterior mirrors
Armrest in the driver's door:
14-way adjustment
2Switching to the other mirror or auto-
matic curb monitor, refer to page 45
To prevent the exterior mirrors from
being damaged due to the width of
the vehicle, always fold them in by hand
before entering an automatic car wash.<
You can also adjust the mirrors manually
if necessary by pressing against the outer
edges of their lenses.
Storing the mirror positions, refer to Seat,
mirror and steering wheel memory,
page 44.
The mirror on the passenger's side
features a lens with a more convex
surface than the mirror installed on the
driver's side. When estimating the distance
between yourself and other traffic, bear in
mind that the objects reflected in the mirror
are closer than they appear. This means
that estimations of the distance to following
traffic should not be regarded as precise.<
Automatic functions
>Both exterior mirrors are automatically
heated in ignition key position 2
>The interior and exterior mirrors dim
depending on the light occurring when
the vehicle is being driven forward
*.There are two photocells in the interior
mirror to control the automatic dimming
of the interior mirror. One is integrated
within the mirror's lens, refer to arrow,
while the other is located at an offset
position on the rear of the mirror hous-
ing.
For trouble-free operation, keep the
photocells clean and do not cover the
area between the interior rearview mir-
ror and the windshield. Do not attach
any kind of stickers on the windshield in
front of the mirror, either.
Steering wheel adjustment
Do not adjust the steering wheel while
the vehicle is moving. There is a risk
of accident from unexpected movement.<
The steering wheel can be adjusted in four
directions.
Storing the steering-wheel position, refer
to Seat, mirror and steering wheel memory,
page 44.
