62 Safety and SecurityOccupant safety
Adjust the driver seat as far as possible
rearward, still permitting proper opera-
tion of vehicle controls. The distance
from the center of the driver’s breast-
bone to the center of the air bag cover
on the steering wheel must be at least
10 in (25 cm) or more. You should be
able to accomplish this by a combina-
tion of adjustments to the seat and
steering wheel. If you have any prob-
lems, please see an authorized
Mercedes-Benz Center.
Do not lean with your head or chest
close to the steering wheel or dash-
board.
Keep hands on the outside of steering
wheel rim. Placing hands and arms in-
side the rim can increase the risk and
potential severity of hand/arm injury
when driver front air bag 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 air bag inflates.
This could result in serious injuries or
death should the air bag be triggered.
Always sit nearly upright, properly use
the seat belts and appropriate size in-
fant or child restraint system.
Children 12 years old and under must
never ride in the front seat, except in a
Mercedes-Benz authorized
BabySmart
TM1
compatible child seat,
which operates with the BabySmart
TM
system installed in the vehicle to deacti-
vate the passenger front air bag when it
is properly installed. Otherwise they will
be struck by the air bag when it inflates
in a crash. If this happens, serious or fa-
tal injury will result.
Failure to follow these instructions can re-
sult in severe injuries to you or other occu-
pants.
If you sell your vehicle, it is important that
you make the buyer aware of this safety in-
formation. Be sure to give the buyer this Op-
erator's Manual.

Warning!
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 front air bag.
BabySmart
TM will not, however, turn off any
side impact air bag.
It should be noted that with respect to both
front and rear side impact air bags there is a
possibility for a side air bag related injury if
occupants, especially children, are not prop-
erly seated or restrained when next to a side
air bag 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 door where the
side air bag inflates. This could result in
70 Safety and SecurityOccupant safetyAutomatic comfort-fit feature seat belt
An automatic comfort-fit feature for front
seats and for the rear outer seats (only for
vehicles with electrically adjustable rear
bench seat* or with individual seats* in the
rear) reduces the retracting force of the
seat belts when they are in normal use.
Preventive occupant safety (PRE-SAFE)
Your vehicle automatically takes preven-
tive measures to better protect the occu-
pants in the following hazardous
situations:
You execute an emergency braking ma-
neuver and the Brake Assist System
(page 81) is activated.
The PRE-SAFE system detects a critical
driving dynamics situation.In such cases, the following systems are
automatically activated:
A front seat belt with the seat belt
buckled is pre-tensioned electrically.
If the occupied front passenger seat or
rear seats are in an unfavorable posi-
tion, they are adjusted to a better posi-
tion. Rear seat adjustment occurs only
in vehicles with individual seats* in the
rear.
The tilt/sliding sunroof closes if the ve-
hicle is in a severe skid or is spinning.
!Do not place objects heavier than
20 lbs (9 kg) on the front passenger
seat. This could cause the front or side
impact air bag on the front passenger
side to deploy in a crash which exceeds
the system's deployment threshold.
Warning
G
The PRE-SAFE system is intended to reduce
the effects of an accident on properly seat
belted vehicle occupants. Despite having
the PRE-SAFE systems in your car, the pos-
sibility of injuries occurring as a result of an
accident cannot be totally eliminated.
Therefore you should always drive carefully
and adjust your driving to the prevailing
road, weather, and traffic conditions.
