• Never wear the shoulder belt under your arm, 
against your neck or off your shoulder. In a 
crash, your body would move too far forward. 
That would increase the chance of head and 
neck injuries. The belt would also apply too 
much force to the ribs or abdomen, which 
could severely injure internal organs such as 
your liver or spleen.• Never wear belts over rigid or breakable 
objects in or on your clothing, such as 
eyeglasses, pens, keys etc., as these might 
cause injuries.• Position the lap belt as low as possible on your 
hips and not across the abdomen. If the belt is 
po s i t i o ne d  ac ro s s  yo u r  a b d om e n ,  i t  c o u l d  c a u se  
serious injuries in a crash.
• Each seat belt should never be used for more 
than one person at a time. Do not fasten a seat 
belt around a person and another person or 
other objects.• Belts should not be worn twisted. In a crash, 
you wouldn’t have the full width of the belt to 
manage impact forces. The twisted belt against 
your body could cause injuries.• Pregnant women should also use a lap-
shoulder belt. The lap belt portion should be 
positioned as low as possible on the hips to 
avoid any possible pressure on the abdomen.• Never place your feet on the instrument panel 
or on the seat. Always keep both feet on the 
floor in front of the seat.

• Occupants, especially children, should never 
lean their heads in the area of the door or rear 
quarter interior trim panel where the side 
airbag inflates. This could result in serious 
injuries or death should the airbag be 
triggered. Always sit upright, properly use the 
seat belts and appropriate size infant or child 
restraint system.• 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.
Failure to follow these instructions can result in 
severe injuries to you or other occupants.
Wa r n i n g !
Accident research shows that the safest place for 
children in an automobile is in the rear seat. 
Should you choose to place a child 12 years old or 
under in the front passenger seat of your vehicle, 
you must properly use a BabySmart
TM 
child 
restraint which will turn off the passenger side 
airbag. BabySmart
TM will not, however, turn off any 
side impact airbag. 
It should be noted that with respect to both front 
and rear side impact airbags there is a possibility 
for a side airbag related injury if occupants, 
especially children, are not properly seated or 
restrained when next to a side airbag which needs 
to deploy rapidly in a side impact in order to do its 
job.

To help avoid the possibility of injury, please follow 
these guidelines: (1) occupants, especially 
children, should never place their bodies or lean 
their heads in the area of the front door or rear 
quarter trim panels where the side airbag inflates. 
This could result in serious injuries or death 
should the side airbag be activated; (2) always sit 
upright, properly use the seat belts and use an 
appropriately sized infant or child restraint system 
for all children 12 years old or under; and (3) 
always wear seat belts properly.
If you believe that, even with the use of these 
guidelines, it would be safer for your rear seat 
occupants to have both rear quarter trim panel 
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 Client Assistance Center at 
1-800-FOR-MERCedes (1-800-367-6372) for details.
