In the case of an accident, liquid electrolyte
may escape the mirror housing if the mirror
glass breaks.
Electrolyte has an irritating effect. Do not al-
low the liquid to come into contact with
eyes, skin, clothing, or respiratory system.
In case it does, immediately flush affected
area with water, and seek medical help if
necessary.
Warning!
G
Exercise care when using the passen-
ger-side exterior rear view mirror. The mirror
surface is convex (outwardly curved surface
for a wider field of view). Objects in mirror
are closer than they appear. Check your in-
terior rear view mirror or glance over your
shoulder before changing lanes. !Electrolyte drops coming into contact
with the vehicle paint finish can only be
completely removed while in their
liquid state and by applying plenty of
water.

When leaving the vehicle, always remove the
SmartKey from the starter switch, and lock
your vehicle. Do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle. Unsupervised use of vehi-
cle equipment may cause an accident
and/or serious personal injury.

60 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
ten inches (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 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
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
result in severe injuries to you or other
occupants.
If you sell your vehicle, it is important that
you make the buyer aware of this safety
information. Be sure to give the buyer this
Operator's Manual.


61 Safety and Security
Occupant safety
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
TM1
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.
1BabySmart
TM is a trademark of Siemens
Automotive Corp.
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
serious injuries or death should the side
air bag be activated.
(2) Always sit nearly upright, properly use
the seat belts and use an appropriately
sized infant or child restraint system for
all children 12 years old or under.
(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 door
mounted side air bags deactivated, then
deactivation can be accomplished upon
your written request to do so at an autho-
rized Mercedes-Benz Center at an additional
cost.
Please contact your local authorized
Mercedes-Benz Center or call our Customer
Assistance Center at 1-800-FOR-MERCedes
(1-800-367-6372) for details.iAir bags are designed to activate only
in certain frontal impacts (front
air bags) and in side impacts (side
impact and head protection window
curtain air bags) which exceed preset
thresholds.
Only during these types of impacts, if of
sufficient severity to meet the deploy-
ment tresholds, will they provide their
supplemental protection.
The driver and passengers should
always wear their seat belts. Otherwise
it is not possible for air bags to provide
their supplemental protection.

67 Safety and Security
Occupant safety
Emergency tensioning device (ETD),
seat belt force limiter
The seat belts for the front and rear outer
seats are equipped with emergency
tensioning devices and belt force limiters.
The ETD is designed to activate in the
following cases:

in frontal or rear-end impacts
exceeding a preset severity level.


if the restraint systems are operational
and functioning correctly.
See 1indicator lamp (
page 58).In an impact, emergency tensioning
devices remove slack from the belts in
such a way that the seat belts fit more
snugly against the body. Belt force limiters
reduce the force exerted by the seat belts
on occupants during a crash.
Children in the vehicle
If an infant or child is traveling with you in
the vehicle:

Secure the child using an infant or child
restraint appropriate to the age and
size of the child.


Make sure that the infant or child is
properly secured by a belt at all times
while the vehicle is in motion.
Infant and child restraint seats and infor-
mation on choosing an appropriate re-
straint system can be obtained from any
Mercedes-Benz Center.
Infant and child restraint systems
Only use a BabySmart
TM1
compatible child
restraint for the front passenger seat in
this vehicle.
iThe ETDs for the front seats will only
activate if the respective front seat belt
is fastened (latch plate properly
inserted into buckle).
The ETDs for the rear outer seats will
activate with or without the respective
seat belt fastened.
Warning!
G
An emergency tensioning device (ETD) that
was activated must be replaced.
When scrapping the emergency tensioning
device, our safety instructions must be
followed. These are available at your
authorized Mercedes-Benz Center.!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.
