BabySmart
TM airbag deactivation system
Special BabySmart
TM compatible child seats, designed 
for use with the Mercedes-Benz system and available at 
any authorized Mercedes-Benz Center are required for 
use with the BabySmart
TM airbag deactivation system. 
With the special child seat properly installed, the 
passenger front airbag will not deploy.
The  ü  indicator lamp located in the center console 
will be illuminated, except with electronic key removed 
or in starter switch position 0. The system does not 
deactivate the door mounted side impact airbag.
Self-test BabySmart
TM without special child seat 
installed
After turning electronic key in starter switch to 
position 1 or 2, the ü  indicator lamp located in the 
center console comes on for approximately 6 seconds 
and then extinguishes.
If the indicator lamp should not come on or is 
continuously lit, the system is not functioning. You must 
see an authorized Mercedes-Benz Center before seating 
any child on the front passenger seat. See page 289 for 
notes on the  ü indicator lamp.

Wa r n i n g !
The BabySmart
TM airbag deactivation system 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 system. 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.The passenger front airbag will not deploy only if 
the  ü  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
TM restraint to transport children 
on the front passenger seat until the system has 
been repaired.

The operational readiness of the airbag system is 
verified by the indicator lamp “SRS” in the instrument 
cluster when turning the electronic key in starter switch 
to position 1. When turning the electronic key in starter 
switch to position 2 the indicator lamp “SRS” in the 
instrument cluster comes on. If no fault is detected, the 
lamp will go out when the engine is running. 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. If the lamp 
does not come on at all or if it fails to extinguish or if it 
comes on thereafter, a malfunction in the system has 
been detected.
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.
Have the system checked at your authorized 
Mercedes-Benz Center immediately.
In the operational mode, after the indicator lamp has 
gone out following the initial check, interruptions or 
short circuits in the airbag ignition circuit and in the 
driver and front passenger seat belt buckle harnesses, 
and low voltage in the entire
 system are detected and 
indicated. Note:
See page 285 for information on the supplemental 
restraint system (SRS) indicator lamp.
Wa r n i n g !
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 Center 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 unnecessarily which could also 
result in injury.

Safety guidelines for the seat belt, emergency 
tensioning retractor and airbag
Wa r n i n g !
If you believe that, even with the use of these 
guidelines, it would be safer for your rear seat 
occupants to have both rear door mounted side 
airbags deactivated, then deactivation can be 
accomplished upon your written election to do so at 
your authorized Mercedes-Benz Center at an 
additional cost. Please contact your local 
authorized Mercedes-Benz Center or call our 
Customer Assistance Center at 1-800-FOR-
MERCedes (1-800-367-6372) for details.
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).

Important!
Prior to operating the vehicle, the driver should check 
and adjust if necessary the seat height, seat position 
fore and aft, and backrest angle to insure adequate 
control, reach and comfort. The head restraint should 
also be adjusted for proper height. See also airbag 
section for proper seat positioning.
In addition, also adjust the steering wheel to ensure 
adequate control, reach, operation and comfort. Both the 
inside and outside rear view mirrors should be adjusted 
for adequate rearward 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 Canadian Motor Vehicle Safety 
Standard 213.
All seat, head restraint, steering wheel, and rear view 
mirror adjustments as well as fastening of seat belts 
should be done before the vehicle is put into motion.
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 
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 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.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.
