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.
i
Adjust the head restraint in such a way that
it is as close to the head as possible.Warning!
G
For your protection, drive only with properly
positioned head restraints.
Adjust head restraint so that the center of
the head restraint supports the back of the
head at eye level. This will reduce the poten-
tial for injury to the head and neck in the
event of an accident or similar situation.
Do not drive the vehicle without the seat
head restraints. Head restraints are intend-
ed to help reduce injuries during an acci-
dent.
51 Getting started
Driving

1Release button
Press release button1 and move the
seat belt height adjuster upward or
downward.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
upright position.
Never use a seat belt for more than one
person at a time.
Do not fasten a seat belt around a
person and another object at the same
time. When using a seat belt to secure
infant restraint or toddler restraint or
children in booster seats, always follow
the child seat manufacturer’s instruc-
tions.
Check your seat belt periodically
during travel to make sure that it is
properly positioned.
Make sure that the seat belt is always
fitted snugly. Take special care of this
when wearing loose clothing. 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.
92 Safety and SecurityOccupant safety
Installation of infant and child restraint
systems
Prior to installing a tether strap, note the
following steps:
Roll up retractable luggage cover and
partition net.
Remove storage box (if so equipped)
(page 275).
If the storage box is not removed:
the top tether anchorage ring located
on the floor (
page 93) for use with a
child restraint in the rear center seat
position cannot be accessed.
the hook of the top tether strap when
attached to the anchorage ring on an
outer rear seat backrest may push
against the storage box and prevent
the backrest from properly locking into
position.
If you place a child seat in the left or
center rear seat position, remove twin
roller blind (
page 276) and return
seat to its original position.
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
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 seat belt posi-
tioning for children over 41 lb until they
reach a height where a lap/shoulder belt fits
properly without a booster.
When the child restraint is not in use, re-
move 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 ac-
cident.
Do not leave children unattended in the ve-
hicle, even if the children are secured in a
child restraint system. Unsupervised chil-
dren in a child restraint system may use ve-
hicle equipment and may cause an accident
and/or serious personal injury.
