erly, refer to page42.

"Fasten safety belts" reminder for
driver's and front passenger seat
The indicator lamps light up and an
acoustic signal sounds. In addition, a
message appears on the Control Dis-
play. Check whether the safety belt
has been fastened correctly.
The "Fa sten safety belts " reminder is iss ued a s
long as the driver's safety belt has not been fas-
tened. The "Fasten safety belts" reminder is
also activated at road speeds above approx.
5 mph or 8 km/h if the front passenger safety
belt is not fastened, if objects are placed on the
front passenger seat, or if driver or front pas-
senger unfasten their safety belts.
Damage to safety belts
If the safety belts are damaged or
stressed in an accident: have the belt sys-
tem, including any belt tensioners or child
restraint systems, replaced and the belt
anchors checked. Have this work done only by
your BMW center or at a workshop that works
according to BMW repair procedures with cor-respondingly trained personnel. Otherwise, it is
not guaranteed that the safety devices will func-
tion properly.<
Coupe: belt hand-over
The concept
The belt hand-over makes it easier for you to
fasten your safety belt. When you close the
door and switch on radio readiness or the igni-
tion, the belt hand-over extends automatically
and presents the in a position that is convenient
for fastening it around you. After you have fas-
tened your safety belt, the belt hand-over
retracts to its original position.
Even if you have not yet fastened your safety
belt, the belt hand-over will retract if you:
>Wait for more than approx. one minute
>Open the corresponding door
>Start driving.
Closing the respective door reactivates the belt
hand-over if the ignition or radio readiness is on.
Front passenger seat
The belt hand-over will extend only if the seat is
occupied and after the front passenger door is
closed.
Pinch protection system
If the belt hand-over encounters resistance on
moving in or out, it moves back slightly in the
opposite direction and stops in this position. To
reactivate the belt hand-over: open and close
the door or switch the ignition off and on.
Although there is a pinch protection sys-
tem, always check that the maneuvering

Adjustments
50 area of the belt hand-over is clear. Otherwise it
cannot be ensured that the system will stop
moving in certain extreme situations.<
Mirrors
Exterior mirrors
The front passenger's mirror is more con-
vex than the driver's mirror. The objects
seen in the mirror are closer than they appear.
Do not gauge your distance from traffic behind
you on the basis of what you see in the mirror;
otherwise, there is an increased risk of an acci-
dent.<

3Folding mirrors in and out*
The setting for the exterior mirrors is stored for
the remote control currently in use
*. The stored
position is called up automatically when the
vehicle is unlocked.
Manual adjustment
The mirrors can also be adjusted manually:
press the edge of the glass.
Folding mirrors in and out*
At driving speeds up to approx. 12 mph/
20 km/h, you can fold the mirrors in and out by
pressing button3. This can be beneficial in nar-
row streets, for example, or for moving mirrors
that were folded in by hand back out into their
correct positions. Mirrors that were folded in are
folded out automatically at a speed of approx.
25 mph/40 km/h.Before entering an automatic car wash,
fold in the exterior mirrors manually or
with button3 to prevent them from being dam-
aged, depending on the width of the vehicle.<
Automatic heating
Depending on the outside temperature, both
exterior mirrors are heated automatically when
the engine is running or the ignition is switched
on.

driver to see the area immediately adjacent
to the vehicle, e.g. a curb, when backing into
a parking space.
Deactivating
Push the switch to the position for the passen-
ger side mirror, arrow 2.

cell is in the mirror frame, see arrow; the other is
on the back of the mirror.
In order to ensure that the system functions
correctly, keep the photo cells clean, do not
cover the area between the interior rearview
mirror and windshield, and do not affix adhesive
labels or stickers of any kind to the windshield
directly in front of the mirror.

Transporting children safely
The right place for children
Do not leave children unattended in the
vehicle; otherwise, they could endanger
themselves and/or other persons by opening
the doors, for example.<
Children always in the rear
Accident research has shown that the safest
place for children is on the rear seat.
Children under the age of 13 or smaller
than 5 ft/150 cm may be transported only
in the rear in suitable child restraint systems
appropriate for their age, weight and size. Oth-
erwise, there is an increased risk of injury in the
event of an accident.<
Children 13 years of age or older must be buck-
led in with a safety belt as soon as there no
longer is any child restraint system that is
appropriate for their age, size and weight.
Exception for front passenger seat
Should it be necessary to use a child
restraint system on the front passenger
seat, the front and side airbags for the front pas-
senger must be deactivated. Otherwise, a child
traveling on that seat will face a significant risk
of injury if the airbags are triggered off, even
with a child restraint system.<
For more information on automatic deactivation
of the front passenger airbags refer to page90.
Installing child restraint
systems
Observe the child restraint system manu-
facturer's instructions when selecting,
installing and using child restraint systems.
Otherwise, the protective effect may be dimin-
ished. <
Standard child restraint systems are designed
to be secured with a lap belt or with the lap-belt
section of a lap-and-shoulder belt. Incorrectly or improperly installed child restraint systems
can increase the risk of injury to children.
Always follow the installation instructions for
the system with the greatest care.
On the front passenger seat
After installing a child restraint system on
the front passenger seat, make sure that
the front and side airbags for the front passen-
ger are deactivated; otherwise, there is an
increased risk of injury if the airbags deploy.<
Seat position
Before installing a child restraint system, move
the front passenger seat as far back and up as
possible to obtain the best possible position for
the belt. Do not change the seat position after
this.
Backrest width*
The backrest width of the front passenger
seat must be at its widest possible set-
ting. Do not change the setting after installing
the child seat. Otherwise, the child seat's stabil-
ity on the front passenger seat is limited.<
1.Adjust the backrest width to its widest set-
ting, refer to page44.
2.Install the child seat.
Child seat security
The rear safety belts and the front passenger
safety belt can be prevented from being pulled
out in order to fasten child restraint systems.

LATCH child restraint fixing
system
LATCH: Lower Anchors and Tethers for CHil-
dren.
To install and use the LATCH child
restraint system, follow the operating and
safety instructions provided by the manufac-
turer of the system; otherwise, the protective
function of the seat may be compromised.<
Mounts for the lower LATCH anchors
Before installing the child seat, pull the belt out
of the area for the child restraint fixing system.
Ensure that both lower LATCH anchors
are correctly engaged and that the child
restraint system is resting firmly against the
backrest; otherwise, the protective function of
