68 Safety and SecurityOccupant safetyInfant and child restraint systems
Use only a BabySmart
TM1
compatible child
restraint for the front passenger seat in
this vehicle.
We recommend that all infants and
children be properly restrained at all times
while the vehicle is in motion. All lap-shoul-
der belts except the driver’s seat belt have
special seat belt retractors for secure fas-
tening of child restraints.
To fasten a child restraint, follow child re-
straint instructions for mounting. Then pull
shoulder belt out completely and let it re-
tract. During the seat belt retraction a
ratcheting sound can be heard to indicate
that the special seat belt retractor is acti-
vated. The belt is now locked. Push down
on child restraint to take up any slack.
To deactivate, release seat belt buckle and
let seat belt retract completely. The seat
belt can again be used in the usual man-
ner.

Warning!
G
Never release the seat belt buckle while the
vehicle is in motion, since the special seat
belt retractor will be deactivated.!The use of infant or child restraints is
required by law in all 50 states, the
District of Columbia, the U.S. territo-
ries and all Canadian provinces.
Infants and small children should be
seated in an appropriate infant or child
restraint system properly secured by a
lap-shoulder belt or, if so equipped, a
child restraint lower anchorage system
that complies with U.S. Federal Motor
Vehicle Safety Standards 213 and 225
and Canadian Motor Vehicle Safety
Standard 213 and 210.2. A statement
by the child restraint manufacturer of
compliance with this standard can be
found on the instruction label on the re-
straint and in the instruction manual
provided with the restraint.
When using any infant or child restraint
system, be sure to carefully read and
follow all manufacturer’s instructions
for installation and use.
Please read and observe warning labels
affixed to inside of vehicle and to infant
or child restraints.

69 Safety and Security
Occupant safety
Warning!
G
Children 12 years old and under must never
ride in the front seat, except in a
Mercedes-Benz authorized BabySmart
TM
compatible child seat, which operates with
the BabySmart
TM System installed in the ve-
hicle to deactivate the passenger front air-
bag when it is properly installed. Otherwise
they will be struck by the airbag when it in-
flates in a crash. If this happens, serious or
fatal injury can result.
According to accident statistics, children
are safer when properly restrained in the
rear seating positions than in the front seat-
ing positions. Infants and small children
must ride in back seats and be seated in an
appropriate infant or child restraint system,
which is properly secured with the vehicle’s
seat belt and top tether strap, or secured via
lower anchors and top tether strap, fully in
accordance with the child seat manufactur-
er’s instructions.
Infants and small children should never
share a seat belt with another occupant.
During an accident, they could be crushed
between the occupant and seat belt.
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
Children too big for child restraint systems
must ride in back seats using regular seat
belts. Position shoulder belt across chest
and shoulder, 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 properly without a booster.
When the child restraint is not in use, re-
move it from the vehicle or secure it with the
seat belt to prevent the child restraint from
becoming a projectile in the event of an ac-
cident.
Do not leave children unattended in the ve-
hicle, even if the children are secured in a
child restraint system. Unsupervised chil-
dren in a child restraint system may use ve-
hicle equipment and may cause an accident
and / or serious personal injury.

71 Safety and Security
Occupant safety
Installation of infant and child restraint
system
Guide top tether strap between head
restraint and top of seat back. Head
restraint must be installed and posi-
tioned such that the top tether strap
can pass freely between the head re-
straint and top of seat back.

Securely fasten the hook1 to the an-
chorage ring2.
For safety, make sure the hook has at-
tached to the ring beyond the safety
catch, as illustrated.Vehicle without third row seats
3Anchorage rings for second row seats
4Anchorage rings for third row seats*
This vehicle is provided with three tether
anchorages3 for a top tether strap be-
hind the second row seats.
Please be sure to check the indicator every
time you use the special system child seat.
Should the light go out while the restraint is
installed, please check installation. If the
light remains out, do not use the
BabySmart
TM restraint to transport children
on the passenger seat until the system has
been repaired.
Warning!
G
Do not place powered-on laptops, cell
phones and like electronic devices on the
passenger seat. Signals from such devices
may interfere with the BabySmart
TM system.
Such signal interference may cause the
7indicator lamp not to come on during
self-test or be continuously lit, indicating
that the system is not functioning.
!Do not use the tether anchorages4
for a top tether strap on a second row
seat.

72 Safety and SecurityOccupant safetyVehicle with third row seats*
3Anchorage rings for second row seats
4Anchorage rings for third row seats*
This vehicle is provided with tether anchor-
ages for a top tether strap behind the
second row seats3 and the third row
seats4.
When using the third row observe the
following:

Installation of infant and child restraint
systems with a top tether strap is al-
lowed only on both third row seats plus
the center second row seat.


When using the center second row seat
for a top tether strap, the left third row
seat should only be used for a child re-
straint system, since exiting the vehicle
may not be possible in an emergency
due to the routing of the top tether
strap.


When installing an infant or child re-
straint system with a top tether strap
on the left second row seat, the left
third row seat should not be occupied. 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 anchor fittings.
1Anchors

Install a LATCH type child seat accord-
ing to the manufacturer’s instructions.
!An infant and child restraint system
must not be installed on the right
second row seat while a passenger
rides in a third row seat. An infant and
child restraint system installed on the
right second row seat will prevent the
use of the easy-entry / exit feature
(page 101).

!Prior to operating the vehicle the driver
should check and adjust the seat
height, seat position fore and aft, and
seat backrest angle if necessary, to en-
sure adequate control, reach and com-
fort. The head restraint should also be
adjusted for proper height. See also the
section on airbags (
page 59) for
proper seat positioning.
In addition, adjust the steering wheel to
ensure adequate control, reach, opera-
tion and comfort. Both the inside and
outside rear view mirrors should be ad-
justed for adequate rear vision.
Fasten seat belts. Infants and small
children should be seated in a properly
secured restraint system that complies
with U.S. Federal Motor Vehicle Safety
Standard 213 and 225 and Canadian
Motor Vehicle Safety Standard 213 and
210.2.
Warning!
G
Do not activate the memory function while
driving. Activating the memory function
while driving could cause the driver to lose
control of the vehicle.

Problem
Possible cause
Suggested solution
7
The indicator lamp comes on.
A BabySmart

child seat is installed on the
front passenger seat. The front passenger
airbag is therefore switched off.

possible by an authorized
Mercedes-Benz Light Truck Center.

The indicator lamp does not light
up with a BabySmart
TM child
seat properly installed on the
front passenger seat.
The system is malfunctioning.

Make sure there is nothing between
seat cushion and child seat and check
installation of the child seat
(page 67).

If the light remains out, have the sys-
tem checked as soon as possible by
an authorized Mercedes-Benz Light
Truck Center.
Do not use the BabySmart
TM restraint
to transport children on the front pas-
senger seat until the system has been
repaired.
