A system malfunction could prevent the
system from responding to an impact
occurring within its normal response range.
Please respond to any signs of malfunction
by having the airbag system inspected
immediately at a BMW center. Transporting children safely 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-restraint system with tether
strap If you use a child-restraint system with a
tether strap, three additional tether
anchorage points have been provided Ð
refer to the arrows in the illustration.
Depending on the location selected for
seating in the rear passenger area, attach
the tether strap to the corresponding
anchorage point to secure the child-
restraint system, as shown in the illustra-
tion below. Each seating position is fitted with a head
restraint.
Outer seating positions:
Lift the head restraint and pass the tether
strap between the headrest and the seat
back. It is recommended to readjust the
head restraint into the lowest possible
position.
Center seating position:
The headrest must be adjusted into the
lowest possible position. Pass the tether
strap over the headrest.
Adjust the tether strap according to the
child-restraint manufacturer's instructions.
Before installing any child-restraint
device or child seat, please read the
following:
Never install a rearward-facing child-
restraint system in the front passenger seat
of this vehicle.
Your vehicle is equipped with an airbag
supplemental restraint system for the front
passenger. Because the backrest on any
rearward-facing child-restraint system Ð of
the kind designed for infants under 1 year
and 20 Ibs./9 kg Ð would be within the
airbag's deployment range, you should
never mount such a device in the front
passenger seat, since the impact of the
airbag against the child-restraint's backrest
could lead to serious or fatal injuries.
If it is necessary for a child Ð not an infant Ð
to ride in the front seat, certain precautions
should be taken. First, move the passenger
seat as far away from the instrument panel
as possible. This important precaution is
intended to maximize the distance
between the airbag and the child. Older
children should be tightly secured with a

Adjustments
58 safety belt after they have outgrown a
booster seat that is appropriate for their
age, height, and weight. Younger children
should be secured in an appropriate
forward-facing child-restraint system that
has first been properly secured with a
safety belt. Never install a rearward-facing
child-restraint system in the front
passenger seat.
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.
Be sure that all occupants Ð of all ages Ð
remain properly and securely restrained at
all times. If your vehicle is equipped with
electric power seats at the rear, these will
need to be returned to their standard
adjustment setting position before a child-
restraint system is used, refer to page 47.
Always press the safety switch for the
power windows before transporting chil-
dren in the rear seats, refer to page 42. This
switch also disables the power rear seat
adjustment. Incorrect or unsupervised
adjustment of the electric power seats
could lead to injuries or damage to the
child-restraint system(s) installed in the
rear.<
All rear seating positions in your vehicle
meet the recommendations of SAE J1819,
an industry recommended practice for
securing child-restraint systems in motor
vehicles.
Child seat security All of the rear belt retractors and the front
passenger's safety belt can be locked for mounting and securing child-restraint
systems.
Information regarding this is located near
the buckle latch of each safety belt.
To lock the belt Pull the entire length of the belt from the
belt retractor. Allow the reel to retract the
belt somewhat and engage the buckle,
then tighten the belt against the child-
restraint system. The retraction mechanism
is now locked. To release the belt Release the buckle, remove the child-
restraint device and allow the belt retractor
to reel the belt completely in. LATCH child-restraint
system
If the vehicle is equipped with electric
power seats, these must be returned
to their standard adjustment setting before
the LATCH child-restraint system can be
used, refer to page 47.<
LATCH: Lower Anchors and Tethers for
Children.
Access to anchorage points The illustration shows the left rear seat as
an example.
The anchorage points for the LATCH child-
restraint system are identified by the flags.
