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 side front airbag will not deploy. The 7 
indicator lamp located in the dashboard will be 
illuminated, except with key removed or in steering lock 
position 0. The system does not deactivate the door 
mounted side impact airbag.Self-test BabySmart

without special child seat installed
After turning key in steering lock to position 1 or 2, the 
7 indicator lamp located in the dashboard comes on 
for approx. 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.BabySmart

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.Follow the manufacturer’s instructions for 
installation of special child seats.The passenger front airbag will not deploy only if 
the 7 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.

Front airbags
The driver and passenger front airbags are designed to 
activate only in certain frontal impacts exceeding a 
preset threshold.
The passenger front airbag deploys only if the front 
passenger seat is occupied, and the 7 indicator la mp 
in the dashboard is not illuminated.
Note:
Heavy objects on the passenger seat can appear to the 
“SRS” to indicate the presence of an occupant in that 
seat which causes the passenger front airbag to deploy 
in a crash exceeding the appropriate threshold.Side impact airbags
The side impact airbags are designed to activate only in 
certain side impacts exceeding a preset threshold. Only 
the side impact airbag on the impacted side of the 
vehicle deploy.
The passenger side impact airbag deploys only if the 
passenger seat is occupied.
Side impact airbags operate best in conjunction with a 
properly positioned and fastened seat belt.
Note:
Heavy objects on passenger seat can cause the 
passenger door side impact airbag to deploy in a crash.
Important!
Airbags are designed to activate only in certain 
frontal (front airbags) impacts, or side (side impact 
airbags) impacts which exceed preset thresholds.
Only during these types of impacts, if of sufficient 
severity to meet the deployment thresholds, will 
they provide their supplemental protection.
The driver and passenger must always wear their 
seat belts, otherwise it is not possible for the airbags 
to provide their intended supplemental protection.

To reduce the risk of injury when the front airbags 
inflate, it is very important for the driver and front 
passenger to always be in a properly seated 
position and to wear your seat belt.
For maximum protection in the event of a collision 
always be in normal seated position w ith  your back 
against the backrest. Fasten your seat belt and 
ensure that it is properly positioned on your body.For unobstructive inflation of door side impact 
airbags, keep door pocket lids closed.Since the airbag inflates with considerable speed 
and force, a proper seating and hands on steering 
wheel position will help to keep you at a safe 
distance from the airbag. 
Occupants who are unbelted, out of position or too 
close to the airbag can be seriously injured by an 
airbag as it inflates with great force in the blink of 
an eye:• 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. 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 wi th you r head or chest close to th e 
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 the driver front airbag 
inflates.• Do not lean against doors.

• 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.• Adjust the passenger seat as far as possible 
rearward from the dashboard when the seat is 
occupied.• Children 12 years old and under must never 
ride in this vehicle, except in a Mercedes-Benz 
authorized BabySmart
TM c ompati ble ch ild 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.
Failure to follow these instructions can result in 
severe or fatal injuries to you or other occupants.
