senger unfasten their safety belts.
Damage to safety belts
If the safety belts are damaged or
stretched in an accident: have the entire
belt system, including the tensioning mecha-
nisms, replaced at your BMW center or at a
workshop that works according to BMW repair
procedures with correspondingly trained per-
sonnel. Have the belt anchorage points
inspected for damage at the same time. Failure
to observe this precaution may prevent the
safety belts from effectively providing optimal
protection when needed.<
Mirrors
Exterior mirrors
The mirror on the front passenger's side
features a lens with a more convex sur-
face 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.<

Transporting children safely

Transporting children safely
The right place for children
Do not leave children unattended in the
vehicle, as they could otherwise endan-
ger themselves and/or other persons by open-
ing the doors, for example.<
As a general rule, the front passenger's seat
and outer rear seats are suitable for installing
universal child-restraint systems for all age
groups, provided that they have been approved
for the age group in question.
Children always in the rear
Accident research shows that the safest place
for children in a vehicle is in the rear seat.
Older children should be tightly secured with a
safety belt, after they have outgrown a booster
seat that is appropriate for their age, height and
weight.
If your BMW is equipped with rear side
airbags, do not allow children to lean
towards the door trim, as serious injuries could
occur if the side airbags are deployed and chil-
dren are too close to the airbags.<
Deactivating rear seat side airbags
Labels in the rear door opening should indicate
the status of your rear seat side airbags. If you
are uncertain of their status, or wish to have the
airbags activated or deactivated, please contact
your BMW center.
Child-restraint system in the rear
Children under the age of 13 or smaller
than 5 ft/150 cm may only be transported
in suitable child-restraint systems on one of the
outer rear seats; otherwise, there is an
increased risk of injury in the event of an acci-
dent.<
Younger children should be secured in an
appropriate child-restraint system that has
been first properly secured to the vehicle.All rear seating positions in your vehicle meet
the recommendations of SAE J1819, an indus-
try-recommended practice for securing child-
restraint systems in motor vehicles.
Exception for front passenger seat
Should it be necessary to use a child-
restraint system on the front passenger
seat, the front passenger airbags must be deac-
tivated. Otherwise, a child traveling on that seat
will be at considerable risk of injury if the airbags
are triggered off, even with a child-restraint sys-
tem. Your vehicle is equipped with an airbag
supplemental restraint system for the front pas-
senger. Because the backrest on any rearward-
facing child-restraint system – of the kind
designed for infants under 1 year and 20 Ibs./
9 kg – would be within the airbag's deployment
range, you should never mount such a system
in the front passenger seat, since the impact of
the airbag against the child restraint's backrest
could lead to serious or fatal injuries.<
For more information on automatic deactivation
of the front passenger airbags refer to page83.
Seat height
Before installing a universal child-restraint sys-
tem, move the front passenger's seat up as far
as it will go to ensure that the safety belt will be
ideally positioned. Do not change the seat
height afterward.
Backrest width
The backrest width of the front passen-
ger's seat must be adjusted to its widest
setting.<
1.After unlocking the vehicle, sit down on the
front passenger seat and close the door.
2.Adjust the backrest width to its widest set-
ting, refer to page40.
3.Install the child seat.

Installing child-restraint
systems
Before installing any child-restraint system or
child seat, read the following:
Observe the child-restraint system man-
ufacturer's instructions for installation
and use. Otherwise the degree of protection
may be reduced. After an accident, have all
parts of the child-restraint system and of the
relevant vehicle safety belt system checked and
replaced if necessary. Have this work done only
at your BMW center or at a workshop that works
according to BMW repair procedures with cor-
respondingly trained personnel.<
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 seat security
All of the rear belt retractors and the front pas-
senger 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 safety 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 unlock the safety belt
Release the buckle, remove the child-restraint
system and allow the belt retractor to reel the
belt completely in.
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, 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 anchor-
age point to secure the child-restraint system,
as shown in the illustration below.
Placement of the tether strap
Outer sitting positions:
Lift the head restraint and pass the tether strap
between the head restraint and the seat back. It
is recommended to readjust the head restraint
into the lowest possible position.
Center sitting position:
Push the center head restraint upward. Guide
the tether strap between the head restraint and
the rear seat back. The tether strap must be
between the anchorages of the head restraint.

Transporting children safely
48 Then push the center head restraint into the
lowest position again.
Adjust the tether strap according to the
child-restraint manufacturer's instruc-
tions.<
LATCH child-restraint fixing system
LATCH: Lower Anchor and Tethers for CHil-
dren.
The rear outer sitting positions are provided
with anchors for a LATCH child-restraint fixing
system.
To attach a child-restraint system with
the LATCH system, follow the operating
and safety instructions of the child-restraint
system manufacturer.<
Rear seat anchorages, with through-
loading system equipment
The anchorage points for the LATCH child-
restraint fixing system are located behind the
indicated protective caps. Flip up the corre-
sponding caps.
Before attaching the LATCH child-restraint fix-
ing system, pull the belt out of the area of the
child-restraint fixing system.
Rear seat anchorages, without
through-loading system
The anchorage points for the LATCH child-
restraint fixing system are located underneath
the identifying symbols.
Before attaching the LATCH child-restraint fix-
ing system, pull the belt out of the area of the
child-restraint fixing system.
