Opening and closing
The key set
1Master keys with remote control.
They specify the functions of the Key
Memory. In the process individual func-
tions of your vehicle can behave differ-
ently depending on the key used, see
further below.
To differentiate, you can mark the keys
with remote controls using the color-
coded decals you received on taking
delivery of the vehicle
There is an extended-life battery
in every master key with remote
control which is charged automatically
in the ignition lock as you drive.
If you have any master keys with remote
control that are not used on a regular
basis, you should therefore remember
to recharge these units by using them
to drive the vehicle for an extended
period at least every six months, also
refer to page 28.<
2Spare key for storage in a safe place,
such as in your wallet.
The locks for the luggage compartment
lid and the hotel function, refer to
page 30, cannot be operated with this
key. This is an advantage in a hotel, for
example. The key is not intended for
constant use
Replacement keys
Additional or replacement keys are avail-
able at your BMW center.
Key Memory
How the system functions
Doubtless you have often reflected on how
great it would be if you could configure
your vehicle's various adjustment settings
to meet your own personal requirements.
BMW has designed several freely select-
able options into the vehicle during its
development. You can set these as desired
via the Control Center.
You can have up to four different basic set-
tings adjusted for four different persons for
the specific keys. The only requirement is
that each person uses his or her own mas-
ter key with remote control.
When your vehicle is unlocked with the
remote control, the vehicle recognizes the
individual key by means of a data exchange
and makes adjustments accordingly.
Examples of Key Memory functions
>Automatic adjustment of the driver's
seat
>Locking the vehicle after moving off
>When unlocking with the remote con-
trol, either unlock only the driver's door
or the entire vehicle
>Activating visual warning for PDC Park
Distance Control
>Resetting volume setting.
Central locking system
The concept
The central locking system is ready for
operation whenever the driver's door is
closed. This simultaneously engages and
releases the locks on the following:
>Doors
>Compartment in the front center con-
sole

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.<
Seat adjustment
To ensure that the safety systems
continue to provide optimized protec-
tion, please observe the adjustment
instructions above.<

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.<
