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 Light Truck Center.• Do not pass belts over sharp edges.• Do not make any modification that could 
change the effectiveness of the belts.• 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.
• 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”.• 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, or front door trim panels, and 
installation of additional electrical / electronic 
equipment on or near “SRS” components and 
wiring. Keep area between airbags and 
occupants free of objects (e.g. packages, 
purses, umbrellas, etc.).

When you sell the vehicle we strongly urge you to give 
notice to the subsequent owner that it is equipped with 
an “SRS” by alerting him to the applicable section in the 
Operator’s Manual.
• In addition, through improper work there is 
the 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 Light Truck 
Center.• 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 at your authorized 
Mercedes-Benz Light Truck 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.

We recommend t ha t all infa nts and children be  properly 
restrained at all times while the vehicle is in motion. All 
lap-shoulder belts except the driver’s seat belt have 
special seat belt retractors for secure fastening of child 
restraints.
To fasten a child restraint follow child restraint 
instructions for routing. 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 manner.
Note:
For child seats with mounting fittings for tether 
anchorages refer to page 67 (installation of infant and 
child restra int systems).Important!
The use of infant or child restraints is required 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 inside 
of vehicle and to infant or child restraints.
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.

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 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.
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.

4Tether anchorages for third row seats
This vehicle is provided with tether anchorages for a top 
tether strap behind the second row seats (3) and the 
third row seats (4).We recommend to install infant and child restraints on 
the third row seats.
When using the third row seats observe the following:
•Installation of infant and child restraint systems 
with a top tether strap is allowed 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 restraint system, since exiting the 
vehicle may not be possible in an emergency due to 
the routing of the top tether strap.
To store the left third row seat, see page 126.
