Occupant safety
If you must install a rear-facing child
restraint on the front passenger seat
because circumstances require you to
do so, make sure that the 56 in-
dicator lamp is illuminated, indicating
that the front passenger front air bag is
deactivated. Should the 56 indi-
cator lamp not illuminate or go out while
the restraint is installed, please check
installation. Periodically check the
56 indicator lamp while driving
to make sure the 56indicator
lamp is illuminated. If the 56 in-
dicator lamp goes out or remains out, do
not transport a child on the front pas-
senger seat until the system has been
repaired. A child in a rear-facing child re-
straint on the front passenger seat will
be seriously injured or even killed if the
front passenger front air bag inflates.If you have to place a child in a
forward-facing child restraint on the
front passenger seat, move the seat as
far back as possible, use the proper
child restraint recommended for the
age, size and weight of the child, and
secure child restraint with the vehicle’s
seat belt according to the child seat
manufacturer’s instructions. For
children larger than the typical
12-month-old child, the front passenger
front air bag may or may not be
activated (
page 65).
iDeployment of the driver front air bag does
not mean that the front passenger front air bag
also should have deployed.
The Occupant Classification System (
page 64)
may have determined:
that the seat was empty or occupied by the
weight up to or less than that of a typical
12-month-old child seated in a standard
child restraint - both instances where the
system suppresses deployment of the front
passenger front air bag even though the im-
pact met the criteria and was of sufficient
severity to deploy the driver front air bag.
that the seat was occupied by a small individ-
ual (such as a young teenager or a small
adult) or a child weighing more than the
weight of a typical 12-month-old child in a
standard child restraint - instances where
the system may suppress deployment of the
front passenger front air bag even though
the impact met the criteria and was of suffi-
cient severity to deploy the driver front air
bag.

Seat belts
The use of seat belts and infant and child
restraint systems is required by law in all
50 states, the District of Columbia, the
U.S. territories and all Canadian provinces.
Even where this is not the case, all vehicle
occupants should have their seat belts
fastened whenever the vehicle is in
motion.
For more information, see “Fastening the
seat belt” (
page 43).
Warning!G
If the 56indicator lamp should not
illuminate, the system is not functioning.
You must see an authorized Mercedes-Benz
Center before seating any child on the front
passenger seat.
Warning!G
Never place anything between seat cushion
and child seat (e.g. pillow), since it reduces
the effectiveness of the Occupant Classifi-
cation System. 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 increasing protec-
tion for the child.
Follow the manufacturer’s instructions for
installation of child seats.
iFor information on infants and children trav-
eling with you in the vehicle and restraint sys-
tems for infants and children, see “Children in
the vehicle” (
page 74).
Warning!G
Always fasten your seat belt before driving
off. Always make sure all of your passengers
are properly restrained, including those sit-
ting in the rear.
Failure to wear and properly fasten and
position your seat belt greatly increases
your risk of injuries and their likely severity
in an accident. You and your passengers
should always wear seat belts.
If you are ever in an accident, your injuries
can be considerably more severe without
your seat belt properly buckled. Without
your seat belt buckled, you are much more
likely to hit the interior of the vehicle or be
ejected from it. You can be seriously injured
or killed.
In the same crash, the possibility of injury or
death is lessened if you are properly wearing
your seat belt. Air bags can only protect as
they are designed if the occupants are
properly wearing their seat belts.

Enhanced seat belt reminder system
When the engine is started, the seat belt
telltale< will always illuminate
for 6 seconds to remind you and your pas-
sengers to fasten your seat belts.
If the driver’s seat belt is not fastened
when the engine is started, an additional
warning chime will also sound for a maxi-
mum of 6 seconds or until the driver’ s
seat belt is fastened.
If after these 6 seconds the driver’s or the
front passenger’s seat belt (with the front
passenger seat occupied) is not fastened
with front doors closed,
the seat belt telltale< remains illu-
minated for as long as either the driv-
er’s or front passenger’s seat belt is not
fastened.
and if the vehicle speed once exceeds
15 mph (25 km/h), the seat belt
telltale< starts flashing and a
warning chime sounds with increasing
and side (front side impact air bags, rear
side impact air bags*, window curtain
air bags and ETD) impacts which exceed
preset deployment thresholds.
Never wear the shoulder belt under your
arm, against your neck or off your shoul-
der. In a frontal crash, your body would
move too far forward. That would
increase the chance of head and neck
injuries. The belt would also apply too
much force to the ribs or abdomen,
which could severely injure internal or-
gans such as your liver or spleen.
Never wear belts over rigid or breakable
objects in or on your clothing, such as
eyeglasses, pens, keys, etc., as these
might cause injuries.
Position the lap belt as low as possible
on your hips and not across the abdo-
m e n . I f t h e b e l t i s p o s i t i o n e d a c r o s s y o u r
abdomen, it could cause serious injuries
in a crash.
Never use a seat belt for more than one
person at a time. Do not fasten a seat
belt around a person and another
person or other objects.
Belts should not be worn twisted. In a
crash, you wouldn’t have the full width
of the belt to distribute impact forces.
The twisted belt against your body could
cause injuries.
Pregnant women should also always use
a lap-shoulder belt. The lap belt portion
should be positioned as low as possible
on the hips to avoid any possible
pressure on the abdomen.
Never place your feet on the instrument
panel, dashboard, or on the seat. Always
keep both feet on the floor in front of the
seat.
When using a seat belt to secure infant
or toddler restraints or children in
booster seats, always follow the child
seat manufacturer’s instructions.

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 at all times while the
vehicle is in motion.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’s
seat belt have special seat belt retractors
for secure fastening of child restraints.
To fasten a child restraint, follow child
restraint instructions for mounting. Then
pull the shoulder belt out completely and
let it retract. During seat belt retraction, a
ratcheting sound can be heard to indicate
that the special seat belt retractor is acti-
vated. The belt is now locked. Push down
on child restraint to take up any slack.
To deactivate, release seat belt buckle and
let seat belt retract completely. The seat
belt can again be used in the usual
manner.
Warning!G
Do not leave children unattended in the
vehicle, even if they are secured in a child
restraint system. The children could
injure themselves on parts of the vehicle
be seriously or fatally injured through
excessive exposure to extreme heat or
cold
If children open a door, they could
injure other persons
get out of the car and injure themselves
or be injured by oncoming traffic
Do not expose the child restraint system to
direct sunlight. The child restraint system’s
metal parts, for example, could become very
hot, and the child could be burned on these
parts.
Do not carry heavy or hard objects in the
passenger compartment or trunk unless
they are firmly secured in place. For more in-
formation, see “Loading” (
page 230), and
see “Useful features” (
page 237) in the
“Controls in detail ” chapter.

!The use of infant or child restraints is
required by law in all 50 states, the District of
Columbia, the U.S. territories, and all Canadian
provinces.
Infants and small children should be seated in an
appropriate infant or child restraint system prop-
erly secured in accordance with the manufactur-
er's instructions for the child restraint, that
complies with U.S. Federal Motor Vehicle Safety
Standards 213 and 225 and Canadian Motor
Vehicle Safety Standards 213 and 210.2.
!A statement by the child restraint manufac-
turer of compliance with these standards can be
found on the instruction label on the restraint
and in the instruction manual provided with the
restraint.
When using any infant, or toddler restraint, or
booster seat, 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.Warning!G
According to accident statistics, children
are safer when properly restrained in the
rear seating positions than in the front seat-
ing position. Thus, we strongly recommend
that children be placed in the rear seats
whenever possible. Regardless of seating
position, children 12 years old and under
must be seated and properly secured in an
appropriate infant or child restraint recom-
mended for the size and weight of the child.
The infant or child restraint must be properly
secured with the vehicle’s seat belt, the seat
belt and top tether strap, or lower anchors
and top tether strap, fully in accordance
with the child seat manufacturer’s instruc-
tions.
Occupants, especially children, should nev-
er place their bodies or lean their heads in
the area of the door where the front side im-
pact air bag and/or the rear side impact
air bag* inflates. This could result in serious
injuries or
76 Safety and Security
Occupant safety
death should the air bag be triggered. Al-
ways sit nearly upright, properly use the
seat belts and use an appropriately sized in-
fant or toddler restraint or booster seat rec-
ommended for the size and weight of the
child.
Children can be killed or seriously injured by
an inflating air bag. Note the following
important information when circumstances
require you to place a child in the front pas-
senger seat:
Your vehicle is equipped with air bag
technology designed to turn off the front
passenger front air bag in your vehicle
when the OCS senses the weight of a
typical 12-month-old child or less along
with the weight of a standard
appropriate child restraint on the front
passenger seat.
A child in a rear-facing child restraint on
the front passenger seat will be
seriously injured or even killed if the
front passenger front air bag inflates in
a collision which could occur under
some circumstances, even with the
air bag technology installed in your vehi-
cle. The only means to completely elim-
inate this risk is to never place a child in
a rear-facing child restraint in the front
seat. We therefore strongly recommend
that you always place a child in a
rear-facing child restraint in the back
seat.
If you must install a rear-facing child
restraint on the front passenger seat
because circumstances require you to
do so, make sure that the
56indicator lamp is illuminated,
indicating that the front passenger front
air bag is deactivated. Should the
56indicator lamp not illuminate
or go out while the restraint is installed,
please check installation. Periodically
check the 56indicator lamp
while driving to make sure the
56indicator lamp is illuminated.
If the 56indicator lamp goes out
or remains out,
do not transport a child on the front pas-
senger seat until the system has been
repaired. A child in a rear-facing child re-
straint on the front passenger seat will
be seriously injured or even killed if the
front passenger front air bag inflates.
If you have to place a child in a
forward-facing child restraint on the
front passenger seat, move the seat as
far back as possible, use the proper
child restraint recommended for the
age, size and weight of the child, and
secure child restraint with the vehicle’s
seat belt according to the child seat
manufacturer’s instructions. For
children larger than the typical
12-month-old child, the front passenger
front air bag may or may not be activat-
ed (
page 65).

Installation of infant and child restraint
systems
This vehicle is equipped with tether
anchorages for a top tether strap at each
of the rear seating positions.
1Cover of top anchorage ring
Make sure the rear backrest is locked
in its upright position (
page 235).
Warning!G
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.
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle
and/or the child is not properly secured in
the child restraint.
Children too big for a toddler restraint must
ride in seats using regular seat belts. Posi-
tion shoulder belt across chest and shoul-
der, not face or neck. A booster seat may be
necessary to achieve proper belt positioning
for children from 41 lbs until they reach a
height where a lap/shoulder belt fits
properly without a booster.
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 an acci-
dent and/or serious personal injury.
