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
appropriately sized infant restraint, toddler
restraint, or booster seat recommended for
the size and weight of the child. For addi-
tional information, see “Children in the vehi-
cle” (
page 57).
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.
iIf PRE-SAFE® has been activated, the front
passenger’s seat and/or electrically adjustable
rear seats* will be moved to a more favorable
seat position.
iThe memory function (page 365) lets you
store the settings for the seat positions together
with the settings for the steering wheel and the
exterior rear view mirrors.
!When moving the seats, make sure there are
no items in the footwell or behind the seats; oth-
erwise, you could damage the seats.

iDepending on the set height of the head re-
straint, the seat fore and aft position is automat-
ically pre-set.Warning!G
When adjusting the front passenger seat,
make sure the seat, if occupied, is as far
from the passenger front air bag as possi-
ble.
Otherwise, the passenger could be seriously
or even fatally injured in the event of an ac-
cident or braking maneuver.
Make sure no one is caught or injured while
the seat is being adjusted.
Even with the SmartKey or 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 unat-
tended in the vehicle, or with access to an
unlocked vehicle. A child’s unsupervised ac-
cess to a vehicle could result in an accident
and/or serious personal injury.

Fastening the seat belts
Warning!G
Always fasten your seat belt before driving
off. Always make sure all of your passengers
are properly restrained.
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 42).
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
appropriately sized infant restraint, toddler
restraint, or booster seat recommended for
the size and weight of the child. For addi-
tional information, see “Children in the vehi-
cle” (
page 57).
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 re-
strained with a separate seat belt. Never use
a seat belt for more than one person at a
time.
Warning!G
Never ride in a moving vehicle with the seat
backrest in an excessively reclined position
as this can be dangerous. You could slide
under the seat belt in a collision. If you slide
under it, the seat belt would apply force at
the abdomen or neck. That could cause se-
rious or even fatal injuries. The seat back-
rest and seat belt provide the best restraint
when the wearer is in a nearly upright posi-
tion and the seat belt is properly positioned
on the body.

Fastening the seat belts
Proper use of seat belts
Do not twist the seat belt when fasten-
ing.
Adjust seat belt so that the shoulder
portion is located as close as possible
to the middle of the shoulder (it should
not touch the neck). Never pass the
shoulder portion of the seat belt under
your arm.
Position the lap belt as low as possible
on your hips (over hip joint) and not
across the abdomen.
Place the seat backrest in a nearly up-
right position.
Never use a seat belt for more than one
person at a time.
Do not fasten a seat belt around a per-
son and another object at the same
time. When using a seat belt to secure
infant restraints or toddler restraints or
children in booster seats, always follow
the child seat manufacturer’s instruc-
tions.
Check your seat belt during travel to
make sure that it is properly posi-
tioned.
Make sure the seat belt is always fitted
snugly. Take special care of this when
wearing loose clothing.For more information, see “Seat belts”
(
page 52).
Seat belt height adjustment
The vehicle automatically adjusts the seat
belt height for the driver’s and front pas-
senger’s seats as well as for the rear outer
seats. Comply with the instructions on how
to properly fasten a seat belt
(
page 368).
Warning!G
Do not pass seat belts over sharp edges.
They could tear.
Do not allow the seat belt to get caught in
the door or in the seat adjustment mecha-
nism. This could damage the seat belt.
Never attempt to make modifications to
seat belts. This could impair the effective-
ness of the seat belts.
Do not bleach or dye seat belts as this may
severely weaken them. In a crash, they may
not be able to provide adequate protection.
Damaged seat belts or seat belts that were
highly stressed in an accident must be re-
placed. Contact an authorized
Mercedes-Benz Center.

The front passenger front
air bag off indicator lamp
does not illuminate and/or
does not remain illuminat-
ed with the weight of a typ-
ical 12-month-old child in a
standard child restraint or
less on the front passen-
ger seat.
The system is malfunctioning.Make sure there is nothing between seat cushion and child seat and
check installation of the child seat.
Make sure no objects applying supplemental weight onto the seat
are present.
Make sure no objects which apply forces to the seat are present
(e.g. objects such as books, briefcases etc. lodged behind or around
the seat, head restraints pushing against roof etc.). The system may
recognize such forces as supplemental weight.
If the front passenger front air bag off indicator lamp remains out,
have the system checked as soon as possible by an authorized
Mercedes-Benz Center. Do not transport a child on the front pas-
senger seat until the system has been repaired.
Also read and observe any messages in the multifunction display
and follow corrective steps (
page 612).
Warning!G
If the59indicator lamp does

enabled
See Oper. ManualFront passenger front air bag is
activated while driving even
though a child, small individual,
or object below the system’s
weight threshold is on the front
passenger seat, or the front pas-
senger seat is empty. Objects
on the seat or forces acting on
the seat may make the system
sense supplemental weight.Stop the vehicle in a safe location as soon as possible and check the front
passenger seat for the following:
Engage the electronic parking brake (page 395).
Switch off the ignition (page 344).
Remove child and child restraint from front passenger seat and properly
secure the child in rear seat employing the child restraint if necessary.
Remove any other items from on and around the front passenger seat and
make sure the storage bag on the back of the front passenger seat is emp-
ty.
Make sure that no objects which apply forces to the seat are present (e.g.
objects such as books, briefcases etc. lodged behind or around the seat,
head restraints pushing against roof etc.). The system may recognize such
forces as supplemental weight and sense that an occupant on the front
passenger seat is of a greater weight than actually present.
Keep the seat unoccupied, close the front passenger door and switch on
the ignition (
page 344).
Monitor the 59indicator lamp right of the instrument cluster
(
