Safety guidelines for the seat belt, emergency
tensioning retractor and airbag
Wa r n i n g !
• Damaged seat belts or belts that were highly
stressed in an accident must be replaced and
their anchoring points must also be checked.
Use only belts installed or supplied by an
authorized Mercedes-Benz Center.• Airbags and “ETR’s” are designed to function
on a one-time-only basis. An airbag or
emergency tensioning retractor (ETR) that was
activated must be replaced.• No modifications of any kind may be made to
any components or wiring of the “SRS”. This
includes changing or removing any component
or part of the “SRS”, the installation of
additional trim material, badges etc. over the
steering wheel hub, front passenger airbag
cover, door trim panels, or door frame trims,
and installation of additional electrical /
electronic equipment on or near “SRS”
components and wiring. Keep area between
airbags and occupants free from objects (e.g.
packages, purses, umbrellas, etc).
• Do not pass belts over sharp edges.• Do not make any modification that could
change the effectiveness of the belts.• Do not use handles above doors for placing
such items as coat hangers etc.•An airbag system component within the
steering wheel gets hot after the airbag has
inflated. Do not touch.• Improper work on the system, including
incorrect installation and removal, can lead to
possible injury through an unintended
activation of the “SRS”.• In addition, through improper work there is a
risk of rendering the “SRS” inoperative or
causing unintended airbag deployment. Work
on the “SRS” must therefore only be performed
by an authorized Mercedes-Benz Center.

notice to the subsequent owner that it is equipped with
an “SRS” by alerting them to the applicable section in
the Operator’s Manual.Infant and child restraint systems
We recommend all infants and children be properly
restrained at all times while the vehicle is in motion. All
lap-shoulder belts except the driver seat belt have
special seat belt retractors for secure fastening of child
restraints.
To activate, 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.
To deactivate, release seat belt buckle and let seat belt
retract completely. The seat belt can again be used in
the usual manner.
Note:
For child seats with mounting fittings for tether
anchorages refer to page 75 (installation of infant and
child restraint systems).
• For your protection and the protection of
others, when scrapping the airbag unit or
emergency tensioning retractor, our safety
instructions must be followed. These
instructions are available from your
authorized Mercedes-Benz Center.• Given the considerable deployment speed and
the textile structure of the airbags, there is the
possibility of abrasions or other injuries
resulting from airbag deployment.
Wa r n i n g !
Never release the seat belt buckle while vehicle is
in motion, since the special seat belt retractor will
be deactivated.

Important!
The use of infant or child restraints is req uired by law in
all 50 states 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, and that complies with
U.S. Federal Motor Vehicle Safety Standard 213 and
Canadian Motor Vehicle Safety Standard 213.
A statement by the child restraint manufacturer of
compliance with this standard can be found on the
instruction label on the restraint 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 the
inside of the vehicle and to infant or child restraints.
Wa r n i n 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 vehicle to deactivate the passenger
front airbag when it is properly installed.
Otherwise they will be struck by the airbag when it
inflates 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 seating 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, fully in accordance with the
child seat manufacturer’s instructions.

This vehicle is provided with tether anchorages for a top
tether strap at each of the rear seating positions.
Prior to installing a tether strap, remove cover (1) from
anchorage ring (2) and store in a convenient place (e.g.
glove box).
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.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. to
the point where a lap / shoulder belt fits properly
without one.When the child restraint is not in use, remove 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 accident.

To secure a tether strap to the anchorage, securely
fasten the hook (3), which is part of the tether strap, to
the anchorage ring (2). For safety, please make sure that
the hook has attached to the ring beyond the safety
catch, as illustrated.
After removing the tether strap, reinstall the cover (1).Child seat mounts
This vehicle is provided with two mounts (at each of the
outer rear seats) for the installation of a child seat
having the matching mounting fittings. The mounts can
be folded back between the seat cushion and the
backrest.
To install a child seat, the mounts (1) must be folded
forward until they lock in place. To do so, grip inner side
of mounts and fold forward. Install child seat according
to the manufacturer’s instructions.
