BabySmart™ Airbag Deactivation System

Special child seats, designed for use with the Mercedes-Benz system and available at any
authorized Mercedes-Benz dealer are required for use with the BabySmart™ airbag deactivation
system. With the special child seat properly insta lled, the passenger front airbag will not deploy. The
indicator lamp located on the center console will be illuminated, except with electronic key
removed or in steering lock position 0. The system does not deactivate the door mounted side
impact airbag.

Warning !

The BabySmart™ Airbag Deactivation System will ONLY work with a special seat designed to
operate with it. It will not work with seats which are not BabySmart™ compatible. Never place
anything between seat cushion and child seat (e .g. pillow), since it reduces the effectiveness
of the deactivation system. Follow the manufacture r's instructions for installation of special
child seats. The passenger side front airbag will not deploy only if the
indicator lamp
remains illuminated. 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™ restraint to transport
children, or otherwise do not transport child restraints on the front passenger seat until the
system has been repaired.


Self-Test BabySmart™ Without Special Child Seat Installed
After turning electronic key in steering lock to position 1 or 2, the
indicator lamp located on
center console comes on for approx. 6 seconds.
If the lamp should not come on or is continuously li t, the system is not functioning. You must see an
authorized Mercedes-Benz dealer before using any child seat.

Emergency Tensioning Retractor (ETR)

The seat belts for the front seats are equipped with emergency tensioning retractors. These tensioning retractors are
located in each belt's inertia reel and become operationally ready with the electronic key in steering lock position 1 or
2. The emergency tensioning retractors are designed to acti vate only when the seat belts are fastened during frontal
impacts exceeding the first threshold of the SRS and in rear impacts exceeding a preset security level. They remove
slack from the belts in such a way that the seat belts fit more snugly against the body restricting its forward movement
as much as possible.
In cases of other frontal impacts, angled impacts, roll-overs, certain side impacts, or other accidents without sufficient
frontal or rear impact forces, the emergency tensioning re tractors will not be activated. The driver and passengers will
then be protected by the fastened seat belts and inertia reel in the usual manner. For seat belt and emergency
tensioning retractor safety guidelines see Safety Guidelines in Index.

Airbags

1. Driver airbag
2. Front passenger airbag
3. Side impact airbag




The most effective occupant restraint system yet developed fo
r use in production vehicles is the seat belt. In some
cases, however, the protective effect of a seat belt can be further enhanced by an airbag. The driver airbag is located
in the steering wheel hub. The passenger airbag is located in the dashboard ahead of the passenger.
The side impact airbags are located in the front doors. In conjunction with wearing the seat belts with emergency
tensioning retractors, the airbags can provide increased protection for the driver and passenger in certain major
frontal or rear impacts (for front airbags) and side impacts (for side impact airbags). The operational readiness of the
airbag system is verified by the indicator lamp "SRS" in the instrument cluster. If no fault is detected, the lamp will go
out after approximately 4 seconds; after the lamp goes out, the system continues to monitor the components and
circuitry of the airbag system and will indicate a malfunction by coming on again.
The following system components are monitored or undergo a self-check: crash-sensor(s), airbag ignition circuits,
front seat belt buckles, emergency tensioning retractors, seat sensor (when present). Initially, when the electronic key
is turned from steering lock position 0 to positions 1 or 2, malfunctions in the crash-sensor are detected and indicated
(the "SRS" indicator lamp stays on longer than 4 seconds). In the operational mode, after the indicator lamp has gone
out following the initial check, interruptions or short circ uits in the airbag ignition circuit and in the driver and
passenger seat belt buckle harnesses, and low voltage in the entire system are detected and indicated.

Warning !
In the event a malfunction of the "SRS" is indicated as outlined above, the "SRS" may not be operational. For
your safety, we strongly recommend that you visit an authorized Mercedes-Benz dealer immediately to have
the system checked; otherwise the "SRS" may not be activated when needed in an accident, which could
result in serious or fatal injury, or it might deploy unexpectedly and unneccesarily which could also result in
injury.


Front Airbags
The driver and passenger front "SRS" airbags are designed to activate only in certain frontal or rear impacts.
The front passenger airbag deploys only if the passenger seat is occupied.

Note:

Heavy objects on passenger seat can cause the front airbag to deploy in a crash.


Side Impact Airbags
The side impact "SRS" airbags are designed to activate onl y in certain side impacts. Only the side airbag on the
impacted side of the vehicle deploys. The side impact ai rbag for the front passenger deploys only if the seat is
occupied. Side impact airbags operate best in conjunct ion with a properly positioned and fastened seat belt.
Note:
Heavy objects on passenger seat can cause the side impact airbag to deploy in a crash

Infant and Child Restraint Systems

We recommend that all infants and children be properly restra ined at all times while the vehicle is in motion. All lap-
shoulder belts except driver seat have special seat belt re tractors for secure fastening of child restraints. To fasten a
child restraint, use this seat belt: Follow child restraint in structions for routing. Then pull shoulder belt out completely
and let it retract. The belt is now locked. Push down on child restraint to take up any slack.

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
213.1. A statement by the child rest raint 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.

Warning !
Children 12 years old and under must never ride in the front seat, except in a Mercedes-Benz authorized
BabySmart™ compatible child seat, which operates with the BabySmart™ system installed in the vehicle to
deactivate the passenger side 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 will result.
The back seat is the safest place for children, 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 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 is necessary to achieve proper belt positioning for children from 41 Ibs. to the point where a
lap/shoulder belt fits properly without one.
When the child restraint is not in use, remove it from the car or secure it with the seat belt to prevent the
child restraint from becoming a projectile in the event of an accident.

U.S.A. Models only:
Since 1986 all U.S. child restraints comply with U.S. regulations without the use of a tether strap. Canada Models
only: This vehicle is provided with tether anchorages for a top tether strap. Consult your authorized Mercedes-Benz
dealer for installation of these anchorages. In compliance with Canadian Motor Vehicle Safety Standard 210.1, child
restraint tether anchorage hardware is attached to the tool kit located in the trunk.

Loading instructions
(Vehicles with enlarged cargo area)

The total load weight including vehicle occupants and luggage/ cargo should not exceed the vehicle capacity weight
indicated on the certification tag which can be found on t he left door pillar. The handling characteristics of a fully
loaded vehicle depend greatly on the load distribution. It is therefore recommended to load the vehicle according to
the illustrations shown, with the heavie st items being placed towards the front of the vehicle. Always place items
being carried against front or rear seat backrests, and fast en them as securely as possible. The heaviest portion of
the cargo should always be kept as low as possible since it influences the handling characteristics of the vehicle.

Notes:
The trunk is the preferred place to carry objects. T he enlarged cargo area should only be used for items which
do not fit in the trunk alone.

Warning !
In an accident, during hard braking or sudden maneuvers, loose items will be thrown around inside the
vehicle, and can cause injury to vehicle occupants unless the items are securely fastened in the vehicle.
To help avoid personal injury during a collision or sudden maneuver, exercise care when stowing things.
Put luggage or cargo in the trunk if possible. Do not pile luggage or cargo higher than the seat backs.
Do not place anything on the shelf below the rear window. Never drive vehicle with trunk lid open while
pass-through is not closed and seat backrest not locked in its upright position. Deadly carbon monoxide
(CO) gases may enter vehicle interior resulting in unconsciousness and death.
