Warning!G
When leaving the vehicle, always remove the
SmartKey or the SmartKey with
KEYLESS-GO* from the starter switch, take
it with you, and lock the vehicle.
Even with the SmartKey or the SmartKey
with KEYLESS-GO* removed from the
starter switch or the SmartKey with
KEYLESS-GO* removed from the vehicle,
the power seats can be operated when the
respective door is open. Therefore, do not
leave children unattended in the vehicle, or
with access to an unlocked vehicle. A child’s
unsupervised access to a vehicle could re-
sult in an accident and/or serious personal
injury.
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 toddler restraint, or
booster seat recommended for the size and
weight of the child. For additional informa-
tion, see “Children in the vehicle”
(
page 82).
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.
iThe memory function (page 123) lets you
store the settings for the seat position together
with the settings for the steering wheel and the
exterior rear view mirrors.
!When moving the seat, make sure there are
no items in the footwell or behind the seats, oth-
erwise you could damage the seats.

48 Getting started
Driving
Fastening the seat belts
Warning!G
Make sure that absolutely no objects are ob-
structing the pedals range of movement.
Keep the driver’s footwell clear of all obsta-
cles. If there are any floormats or carpets in
the footwell, make sure that the pedals still
have sufficient clearance.
During sudden driving or braking maneuvers
the objects could get caught between the
pedals. You could then no longer brake or
accelerate. This could lead to accidents and
injury.
Warning!G
Always fasten your seat belt before driving
off. Always make sure all of your passengers
are properly restrained, even those sitting 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 wearing your
seat belt. The air bags can only provide the
protection they were designed to afford if
the occupants are using their seat belts
(
page 76).
Warning!G
According to accident statistics, children
are safer when properly restrained in the
rear seating positions than in the front
seating position. Thus, we strongly recom-
mend that children be placed in the rear
seats. Regardless of seating position, chil-
dren 12 years old and under must be seated
and properly secured in an appropriate in-
fant or toddler restraint, or booster seat rec-
ommended for the size and weight of the
child. For additional information, see “Chil-
dren in the vehicle” (
page 82).
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.
Warning!G
Never let more people ride in the vehicle
than there are seat belts available. Be sure
everyone riding in the vehicle is correctly
restrained with a separate seat belt. Never
use a seat belt for more than one person at
a time.

67 Safety and Security
Occupant safety

Occupants, especially children, should
never place their bodies or lean their
heads in the area of the door where the
side impact air bag inflates. This could
result in serious injuries or death should
the air bag be triggered. Always sit as
upright as possible, properly use the
seat belts and use an appropriately
sized infant restraint, toddler restraint,
or booster seat recommended for the
size and weight of the child.
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.Warning!G
Accident research shows that the safest
place for children in an automobile is in the
rear seat.
It should be noted that with respect to both
front and rear side impact air bags there is a
possibility for a side impact air bag related
injury if occupants, especially children, are
not properly seated or restrained when next
to a side impact 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 impact air bag inflates. This could
result in serious injuries or death should
the side impact air bag be deployed.
(2) Always sit as upright as possible, prop-
erly use the seat belts, and for children
12 years old and under, use an appropri-
ately sized infant restraint, toddler re-
straint, or booster seat recommended
for the size and weight of the child.
(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 the rear mount-
ed side impact air bags deactivated, then
deactivation can be accomplished upon
your written request to do so at your 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.

70 Safety and Security
Occupant safety
The air bags will not deploy in impacts
which do not exceed the system’s deploy-
ment thresholds. You will then be protect-
ed by the fastened seat belts.The front passenger air bag will only be
deployed if:

the front passenger seat is occupied

the 75indicator lamp in
the center console is not lit
(
page 75)

the impact exceeds a preset deploy-
ment threshold
Knee bag
The knee bag is located on the driver-side
lower instrument panel. It is designed to
operate together with the driver air bag in
certain frontal impacts exceeding a preset
threshold. The knee bag operates best in
conjunction with a properly positioned and
fastened seat belt.Side impact air bags, window curtain
air bags
1Front side impact air bags
2Window curtain air bag
3Rear side impact air bags
iThe front air bags in this vehicle have been
designed to inflate in two stages. This allows the
air bag to have different rates of inflation that are
based on the rate of vehicle deceleration as as-
sessed by the air bag control unit.
On the front passenger side, the front air bag de-
ployment is additionally influenced by the pas-
senger’s weight category as identified by the
Occupant Classification System (OCS)
(
page 71).
The lighter the front passenger side occupant,
the higher the vehicle deceleration rate required
for the second stage inflation of the air bag.

71 Safety and Security
Occupant safety
The side impact air bags and window cur-
tain air bags are deployed:

on the impacted side of the vehicle

in impacts exceeding a preset deploy-
ment threshold

independently of the front air bags
In addition, the window curtain air bags2
are deployed:

in certain vehicle rollovers
The side impact air bags and window cur-
tain air bags are not deployed in impacts
which do not exceed the system’s deploy-
ment threshold.
Occupant Classification System
The Occupant Classification System (OCS)
automatically turns the front passenger
front air bag on or off based on the classi-
fied occupant weight category determined
by weight sensor readings from the front
passenger seat.
Occupants must sit properly belted in a po-
sition that is as upright as possible with
their back against the seat backrest and
feet on the floor to be correctly classified.
If the occupant’s weight is transferred to
another object in the vehicle (e.g. by lean-
ing on armrests), the OCS may not be able
to properly approximate the occupant’s
weight category. Furthermore, the occupant weight may ap-
pear to increase or decrease due to
objects hanging on the seat, other passen-
gers pushing on the seat, objects lodged
underneath the seat or stuffed between
seat and middle console or between seat
and door or due to objects applying pres-
sure on the back of the seat. Always make
sure that the seat has clearance in all di-
rections at all times.
Both driver and the front passenger should
always use the 75 indicator
lamp as an indication of whether or not the
front passenger is properly positioned.
iThe system does not deactivate the front
passenger side impact air bag, the window cur-
tain air bag and the Emergency Tensioning De-
vice.
iIf your seat, including your trim cover and
cushion needs to be serviced in any way, take
the vehicle to an authorized Mercedes-Benz
Center.
Only seat accessories approved by
Mercedes-Benz may be used.

Occupant safety
Warning!G
If the 75 indicator lamp illumi-
nates when an adult or someone larger than
a small individual is in the front passenger
seat, have the front passenger re-position
himself or herself in the seat until the
75 indicator lamp goes out, or
check whether objects are caught under or
around the seat.
More information about air bag display mes-
sages (
page 364).
In the event of a collision, the air bag control
unit will not allow front passenger front
air bag deployment when the OCS classified
the front passenger seat occupant as being
up to or less than the weight of a typical
12-month-old child in a standard child re-
straint or if the front passenger seat is
sensed as being empty.
When the OCS senses that the front passen-
ger seat occupant is classified as being up
to or less than the weight of a typical
12-month-old child in a standard child re-
straint, the 75 indicator lamp
will illuminate when the engine is started
and remain illuminated, indicating that the
front passenger front air bag is deactivated.
When the OCS senses that the front passen-
ger seat is classified as being empty, the
75 indicator lamp will illumi-
nate when the engine is started and remain
illuminated, indicating that the front passen-
ger front air bag is deactivated. When the OCS senses that the front passen-
ger seat occupant is classified as being
heavier than the weight of a typical
12-month-old child seated in a standard
child restraint or as being a small individual
(such as a young teenager or a small adult),
the 75 indicator lamp will illu-
minate for approximately 6 seconds when
the engine is started and then, depending on
occupant weight sensor readings from the
seat, remain illuminated or go out. With the
75 indicator lamp illuminated,
the front passenger front air bag is deacti-
vated. With the 75 indicator
lamp out, the front passenger front air bag is
activated.

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.
Always sit as upright as possible, properly
use the seat belts and for children 12 years
old and under, use an appropriately sized in-
fant restraint, toddler restraint, or booster
seat recommended for the size and weight
of the child.
Children can be killed or seriously injured by
an inflating air bag. Note the following im-
portant information when circumstances re-
quire you to place a child in the front
passenger seat:

Your vehicle is equipped with air bag
technology designed to turn off the front
passenger front air bag in your vehicle
when the system senses the weight of a
typical 12-month-old child or less along
with the weight of a standard appropri-
ate child restraint on the front passen-
ger seat.

A child in a rear-facing child restraint on
the front passenger seat will be serious-
ly injured or even killed if the front pas-
senger front air bag inflates in a collision
which could occur under some circum-
stances, even with the air bag technolo-
gy installed in your vehicle. The only
means to completely eliminate 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.


74 Safety and Security
Occupant safety

If you must install a rear-facing child re-
straint on the front passenger seat be-
cause circumstances require you to do
so, make sure that the
75indicator lamp is illumi-
nated, indicating that the front passen-
ger front air bag is deactivated. Should
the indicator lamp not illuminate or go
out while the restraint is installed,
please check installation. Periodically
check the indicator lamp while driving to
make sure the lamp is illuminated. If the
75indicator lamp goes out
or remains out, do not transport a child
on the front passenger seat until the
system has been repaired. 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.
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 se-
cure 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 72).
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 71)
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


75 Safety and Security
Occupant safety
The 75 indicator lamp is lo-
cated in the center console.
1Indicator lamp
The 75 indicator lamp1 will
be illuminated, except with the SmartKey
removed or in starter switch position0
(
page 38).
Warning!G
If the 1indicator lamp and the
75 indicator lamp are lit at the
same time, there is a malfunction in the
Occupant Classification System. The front
passenger front air bag will be deactivated
in this case.
Have the system checked as soon as possi-
ble by qualified technicians. Contact an au-
thorized Mercedes-Benz Center.
Only have the seat repaired or replaced by
an authorized Mercedes-Benz Center.
In order to ensure proper operation of the
air bag system and OCS:

Do not place more than 4.4 lbs (2 kg)
into the ruffled storage bag on the back
of the front passenger seat. Otherwise,
the OCS may not be able to properly ap-
proximate the occupant weight
category.

Do not place objects under and/or
around the front passenger seat.

Do not hang anything from or attach any
items to the seats.

Do not stuff objects such as books be-
tween the middle console and the front
passenger seat.

Do not move the front passenger seat
backwards against stiff objects.

Sit properly belted in a position that is
as upright as possible with your back
against the seat backrest.

While seated, an occupant should not
position him/herself in such a way as to
cause the occupant’s weight to be lifted
from the seat bottom as this may result
in the OCS being unable to correctly ap-
proximate the occupant’s weight cate-
gory.

Read and observe all warnings in this
chapter.
