2007 MERCEDES-BENZ R320CDI child seat

91 Safety and Security
Occupant safety

If you must install a rear-facing child
restraint on the front passenger seat
because circumstances require you to
do so, make sure that the
59 indicator lamp is illumi-
nated, indicating that the front passen-
ger front air bag is deactivated. Should
the 59 indicator lamp not
illuminate or go out while the restraint is
installed, please check installation. Peri-
odically check the 59 indi-
cator lamp while driving to make sure
the 59 indicator lamp is il-
luminated. If the 59 indica-
tor lamp goes out or remains out, do not
transport a child on the front passenger
seat until the system has been repaired.
A child in a rear-facing child restraint on
the front passenger seat will be serious-
ly injured or even killed if the front pas-
senger front air bag inflates.
If you have to place a child in a
forward-facing child restraint on the
front passenger seat, move the seat as
far back as possible, use the proper
child restraint recommended for the
age, size and weight of the child, and se-
cure child restraint with the vehicle’s
seat belt according to the child seat
manufacturer’s instructions. For
children larger than the typical
12-month-old child, the front passenger
front air bag may or may not be activat-
ed (
page 88).
iDeployment of the driver front air bag does
not mean that the front passenger front air bag
also should have deployed.
The Occupant Classification System (
page 88)
may have determined:

that the seat was empty or occupied by the
weight up to or less than that of a typical
12-month-old child seated in a standard
child restraint – both instances where the
system suppresses deployment of the front
passenger front air bag even though the im-
pact met the criteria and was of sufficient
severity to deploy the driver front air bag

that the seat was occupied by a small individ-
ual (such as a young teenager or a small
adult) or a child weighing more than the
weight of a typical 12-month-old child in a
standard child restraint – instances where
the system may suppress deployment of the
front passenger front air bag even though
the impact met the criteria and was of suffi-
cient severity to deploy the driver front air
bag

Self-test Occupant Classification Sys-
tem
After turning the SmartKey in the starter
switch to position1or2or pressing the
KEYLESS-GO* start/stop button once or
twice, the59indicator lamp
(
page 92) located in the center console
illuminates. If an adult occupant is properly
sitting on the front passenger seat and the
system senses the occupant as being an
adult, the59indicator lamp
will illuminate and go out after approxi-
mately 6 seconds.
If the seat is not occupied and the system
senses the front passenger seat as being
empty, the59indicator lamp
will illuminate and not go out.For more information, see the “Practical
hints” section (
page 431).Child seat anchors – LATCH type
This vehicle is equipped with two LATCH
(L
ower Anchors and Tethers for CHildren)
type anchors (at each of the second and
third-row seats) for the installation of a
LATCH child seat with matching mounting
fittings.
Warning!G
If the 59 indicator lamp should
not illuminate, the system is not functioning.
You must see an authorized Mercedes-Benz
Light Truck Center before seating any child
on the front passenger seat.
Warning!G
Never place anything between seat cushion
and child seat (e.g. pillow), since it reduces
the effectiveness of the Occupant
Classification System. The bottom of the
child seat must make full contact with the
passenger seat cushion. An incorrectly
mounted child seat could cause injuries to
the child in case of an accident, instead of
increasing protection for the child.
Follow the manufacturer’s instructions for
installation of child seats.
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 over
41 lbs until they reach a height where a
lap/shoulder belt fits properly without a
booster.
Install child seat according to manufactu-
rer’s instructions.
The child seat must be firmly attached to the
right and left side anchors.

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
vehicle, even if the children are secured in a
child restraint system.
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.

96 Safety and Security
Occupant safety
Securely fasten hook3, which is part
of top tether strap4, to anchorage
ring2.
Make sure

the top tether strap is not twisted

the head restraint is installed and
positioned such that the top tether
strap* can pass freely between the
head restraint and top of seat back-
rest

top tether strap is positioned be-
tween the seat backrest and the
cargo compartment cover blind*
(if installed)

the top tether strap is positioned
between the seat backrest and the
partition net* (if installed)
Fold seat backrest up and push back-
wards until it audibly engages.
A second-row seat is properly locked
only when lock status indicator 1 is in
hinged position and red marking 2 is
barely visible (
page 135).
Warning!G
When installing a child seat on a third-row
seat, do not fasten hook 3 to the strap
below 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 secured in the vehicle.
Warning!G
After installing top tether straps, make sure

the seats are properly locked

the seat backrests are in an upright po-
sition and are properly locked
A second-row seat is properly locked only
when lock status indicator 1 is in hinged
position and red marking 2 is barely visible
(
page 135).
If a seat and seat backrest are not properly
locked, the seat could move forward and the
seat backrest could fold. The child seat
would no longer be properly supported or
positioned to provide its intended benefit.
That could cause serious or even fatal
injuries.


97 Safety and Security

selves, e.g. by becoming trapped in the
window 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.

Front seat active head restraints
You cannot remove the active head
restraints on the driver’s and front passen-
ger’s seat.
For removal of the active head restraints
we recommend that you contact an
authorized Mercedes-Benz Light Truck
Center.
For information on head restraint adjust-
ment, see “Seats” (
page 43).
For information on active head restraints,
see “Active head restraints” (
page 83).
Rear seats Rear seat adjustment
Warning!G
For your protection, drive only with properly
positioned head restraints.
Adjust the head restraint so that it is close
to the head as possible and the center of the
head restraint supports the back of the head
at eye level. This will reduce the potential for
injury to the head and neck in the event of
an accident or similar situation.
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 84).
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 51).
Never place hands under the seat or near
any moving parts while a seat is being ad-
justed.
