G
All seat, head restraint, steering wheel, and 
rear view mirror adjustments, as well as fas-
tening of seat belts, must be done before 
the vehicle is put into motion.Warning!
G
Do not adjust the driver’s seat while driving. 
Adjusting the seat while driving could cause 
the driver to lose control of the vehicle.
Never ride in a moving vehicle with the seat 
back reclined. Sitting in an excessively re-
clined position can be dangerous. You could 
slide under the seat belt in a collision. If you 
slide under it, the belt would apply force at 
the abdomen or neck. That could cause se-
rious or fatal injuries. The seat back and seat
belts provide the best restraint when the 
wearer is in an upright position and belts are 
properly positioned on the body. Your seat 
must be adjusted so that you can correctly 
fasten your seat belt (
page 37).
Never place hands under the seat or near 
any moving parts while a seat is being ad-
justed.
Warning!
G
When leaving the vehicle, always remove the 
key from the starter switch, take the KEY-
LESS-GO
* card (if so equipped) with you, 
and lock your vehicle.
The power seats can also be operated with 
the appropriate door open. Do not leave 
children unattended in the vehicle, or with 
access to an unlocked vehicle. Unsuper-
vised use of vehicle equipment may cause 
an accident and/or serious personal injury.
Warning!
G
Children 12 years old and under must never 
ride in this vehicle, except in a 
Mercedes-Benz authorized BabySmart
TM 
compatible child seat, which operates with 
the BabySmart
TM system installed in the ve-
hicle to deactivate the passenger side front 
airbag when it is properly installed. Other-
wise they will be struck by the airbag when 
it inflates in a crash. If this happens, serious 
or fatal injury will result.
Infants and small children must be seated in 
an appropriate infant or child restraint sys-
tem, which is properly secured with the ve-
hicle’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. 
65 Safety and Security
Occupant safety
The 
7
indicator lamp located on the 
glove box will be illuminated, except with 
the key removed or in the starter switch 
position0.
Self-test BabySmart
TM
 without special 
child seat installed
After turning the key in the starter switch 
to position1 or2, the 7
 indicator lamp 
located on the glove box lights up for ap-
prox. 6 seconds and then goes out.
If the indicator lamp should not come on or 
is continuously lit, the system is not func-
tioning. You must see an authorized 
Mercedes-Benz Center before seating any 
child on the passenger seat.
iThe system does not deactivate the 
head-thorax airbag and the emergency 
tensioning device.
Warning!
G
The BabySmart
TM airbag deactivation sys-
tem 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 sys-
tem. 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.
Warning!
G
When using a BabySmart compatible child 
seat on the front passenger seat, the front 
passenger 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 passenger seat until the system has 
been repaired.
