Emergency tensioning device (ETD),
seat belt force limiter
The seat belts for the front and rear outer
seats are equipped with emergency ten-
sioning devices and belt force limiters.
The ETD is designed to activate only when
the seat belt is fastened and in the follow-
ing cases:
in frontal or rear-end impacts exceed-
ing a preset severity level
if the restraint systems are operational
and functioning correctly, see
1indicator lamp (
page 56)
In an impact, emergency tensioning devic-
es remove slack from the belts in such a
way that the seat belts fit more snugly
against the body.
Children in the vehicle
If an infant or child is traveling with you in
the vehicle:
Secure the child using an infant or child
restraint appropriate to the age and
size of the child and recommended for
use by Mercedes-Benz.
Make sure the infant or child is proper-
ly secured by a belt at all times while
the vehicle is in motion.
Infant and child restraint seats and infor-
mation on choosing an appropriate re-
straint system can be obtained from any
Mercedes-Benz Light Truck Center.
Warning!
G
An emergency tensioning device (ETD) that
was activated must be replaced.
When disposing of the emergency tension-
ing device, our safety instructions must be
followed. These are available at your autho-
rized Mercedes-Benz Light Truck Center.!Do not place objects heavier than
20 lbs (9 kg) on the front passenger
seat. This could cause the passenger
front airbag to deploy in a crash which
exceeds the system's deployment
threshold.

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 manufac-
turer’s instructions for mounting child re-
straints. Then pull shoulder belt out
completely and let it retract. During the
seat belt retraction a ratcheting sound can
be heard to indicate that the special seat
belt retractor is activated. 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.

with mounting fittings for tether an-
chorages, see “Installation of infant
and child restraint system”
(page 69).
For information on LATCH-type child
seat anchors, see (
page 70).
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
Standards 213 and 210.2.
A statement by the child restraint man-
ufacturer of compliance with this stan-
dard can be found on the instruction
label on the restraint and in the instruc-
tion manual provided with the restraint.

67 Safety and Security
Occupant safety
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.
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.

For more information, see “Practical hints”
section (

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 serious
personal injury.

Warning!
G
The BabySmart
TM airbag deactivation sys-
tem will ONLY work with a special child seat
designed to operate with it. It will not work
with child seats which are not BabySmart
TM
compatible.
Never place anything between seat cushion
and child seat (e.g. pillow), since it reduces
the effectiveness of the deactivation sys-
tem. 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 protecting the child.
Follow the manufacturer’s instructions for
installation of special child seats.
When using a BabySmart
TM compatible
child seat on the front passenger seat, the
passenger front airbag will not deploy only if
the 7 indicator lamp remains illuminat-
ed.
Warning!
G
Make 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 front passenger seat until the system
has been repaired.
Warning!
G
Do not place powered-on laptops, cell
phones and like electronic devices on the
front passenger seat. Signals from such de-
vices may interfere with the BabySmart
TM
system. Such signal interference may cause
the 7 indicator lamp not to come on dur-
ing self-test or be continuously lit, indicating
that the system is not functioning.
