iWhen installing a child seat and top
tether on a rear seat if a cargo compart-
ment cover blind* or a partition net* is
in place behind that rear seat, make
sure the top tether strap is positioned
between the seat backrest and the
cargo compartment cover blind* or
partition net* in order for the child seat
to be properly secured.
Warning!
G
When installing a child seat on a third-row
seat, do not fasten hook 3 to the strap be-
low anchorage ring 2. Otherwise, the child
seat will not be securely fastened. A child’s
risk of serious or fatal injuries is significantly
increased if the child seat is not properly se-
cured in the vehicle.iFor safety, make sure the hook has at-
tached to the ring beyond the safety
catch, as illustrated.


92 Safety and SecurityOccupant safetyOnce the top tether anchorage hook is
attached, the child restraint itself can be
secured. Tighten the top tether strap
according to the child restraint manufac-
turer’s instructions.Child seat anchors – LATCH type
This vehicle is equipped with two LATCH
(L
ower A
nchors and T
ethers for CH
ildren)
type anchors (at each of the rear seats) for
the installation of a LATCH child seat with
matching mounting fittings.
The LATCH anchors on the second-row
seats are covered with an upholstery
blend.

Install a LATCH type child seat accord-
ing to the manufacturer’s instructions.
Blocking of rear door window operation
With the override switch you can disable
the rear side window switches in the rear
door panels.
iNon-LATCH type child seats may also
be used and can be installed using the
vehicle’s seat belt system. Install child
seat according to the manufacturer’s
instructions.
Warning!
G
Children too big for a toddler restraint must
ride in seats using regular seat belts. Posi-
tion shoulder belt across chest and shoul-
der, not face or neck. A booster seat may be
necessary to achieve proper belt positioning
for children from 41 lbs until they reach a
height where a lap / shoulder belt fits prop-
erly without a booster.
Install child seat according to manufactu-
rer’s instructions.
The child seat must be firmly attached in the
right and left side anchors 1.
An incorrectly mounted child seat may come
loose during an accident which could result
in serious injury or death to the child.
Damaged or impact damaged child seats or
child seat mounting fittings must be re-
placed.
Do not leave children unattended in the ve-
hicle, even if the children are secured in a
child restraint system.
Warning!
G
Activate the override switch when children
are riding in the back seats of the vehicle.
The children may otherwise injure them-
selves, e.g. by becoming trapped in the win-
dow opening.
When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock the vehicle. Do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle. Unsupervised use of vehi-
cle equipment may cause an accident
and/or serious personal injury.

Warning!
G
According to accident statistics, children
are safer when properly restrained in the
rear seating positions than in the front seat-
ing position. Thus, we strongly recommend
that children be placed in the rear seats. Re-
gardless of seating position, children 12
years old and under must be seated and
properly secured in an appropriate infant or
toddler restraint, or booster seat recom-
mended for the size and weight of the child.
For additional information, see “Children in
the vehicle” (
page 82).
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle and
the child is not properly secured in the child
restraint.
Warning!
G
Never ride in a moving vehicle with the seat
backrest in an excessively reclined position
as this can be dangerous. You could slide
under the seat belt in a collision. If you slide
under it, the belt would apply force at the ab-
domen or neck. That could cause serious or
fatal injuries. The seat backrest and seat
belts provide the best restraint when the
wearer is in a nearly upright position and
belts are properly positioned on the body.
Your seat must be adjusted so that you can
correctly fasten your seat belt (
page 50).
Never place hands under the seat or near
any moving parts while a seat is being ad-
justed.

The front passenger
front air bag off indicator
lamp does not illuminate
and/or does not remain
illuminated with the
weight of a typical
12-month-old child in a
standard child restraint or
less on the front passen-
ger seat.
The system is malfunction-
ing.

Make sure there is nothing between seat cushion and
child seat and check installation of the child seat.

Make sure no objects applying supplemental weight
onto the seat are present.

Make sure no objects which apply forces to the seat
are present (e.g. objects such as books, briefcases
etc. lodged behind or around the seat, head restraints
pushing against roof etc.). The system may recognize
such forces as supplemental weight.

If the front passenger front air bag off indicator lamp
remains out, have the system checked as soon as pos-
sible by an authorized Mercedes-Benz Light Truck
Center. Do not transport a child on the front passen-
ger seat until the system has been repaired.

Also note any messages in the multifunction display
and follow corrective steps (
page 423).

Front passenger front
air bag is activated
while driving even
though a child, small
individual, or object
below the system’s
weight threshold is on
the front passenger
seat, or the front pas-
senger seat is empty.
Objects on the seat or
forces acting on the
seat may make the
system sense supple-
mental weight.
Stop the vehicle in a safe location as soon as possible and check the front passen-
ger seat for the following:
Turn off the ignition (
page 38).

Remove child and child restraint from front passenger seat and properly secure
the child in rear seat employing the child restraint if necessary.

Remove any other items from on and around the front passenger seat and
make sure the storage bag on the back of the front passenger seat is empty.

Make sure that no objects which apply forces to the seat are present (e.g. ob-
jects such as books, briefcases etc. lodged behind or around the seat, head re-
straints pushing against roof etc.). The system may recognize such forces as
supplemental weight and sense that an occupant on the front passenger seat
is of a heavier weight than actually present.

Keep the seat unoccupied, close the front passenger door and turn on the igni-
tion (
