• Sit properly belted in an upright position with 
your back against the backrest.• Adjust the driver seat as far as possible 
rearward, still permitting proper operation of 
vehicle controls. The distance from the center 
of the driver’s breastbone to the center of the 
airbag cover on the steering wheel must be at 
least ten inches (25 cm) or more. You should be 
able to accomplish this by a combination of 
adjustments to the seat and steering wheel. If 
you have any problems, please see your 
authorized Mercedes-Benz Center.• Do not lean with your head or chest close to the 
steering wheel or dashboard.• Keep hands on the outside of steering wheel 
rim. Placing hands and arms inside the rim 
can increase the risk and potential severity of 
hand / arm injury when driver front airbag 
inflates.• Adjust the front passenger seat as far as 
possible rearward from the dashboard when 
the seat is occupied.
• Occupants, especially children, should never 
lean their heads in the area of the door where 
the side airbag inflates. This could result in 
serious injuries or death should the airbag be 
triggered.• Children 12 years old and under must never 
ride in the front seat, except in a 
Mercedes-Benz authorized Baby Smart
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 
front airbag. BabySmart
TM will not, however, turn 
off the vehicle’s 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.
Wa r n i n g !
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 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.

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 84 (installation of infant and 
child restraint 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 the 
inside of the 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.

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.
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.Do not leave children unattended in the vehicle; 
even if the children are secured in a child restraint 
system. Unsupervised children in a child restraint 
system may use vehicle equipment and may cause 
serious personal injury.
