Index
Adjust the seat belt so that the upper part
of the belt is as close as possible to the
center of the shoulder. It should not touch
the neck. Never route the belt under the
shoulder. The height of the belt outlet can
be altered to ensure correct usage.
R The lap belt should be routed as low as
possible across the hips, not across the
abdomen. If
the lap belt is routed across the
abdomen, it could cause serious injuries in
the event of an impact.
R Never route the seat belt over rigid or
fragile objects in or on your clothing, such
as eyeglasses, pens, keys etc, as this could
cause injuries.
R Always ensure that the seat belt is routed
correctly. This is particularly important if
you are wearing loose clothing.
R Only one person should use each seat belt
at any one time. Never use a seat belt to
restrain more than one person or route the
belt around additional objects.
R Never wear seat belts when they are
twisted. Otherwise, in the event of an
impact, the full width of the seat belt is
unavailable to distribute the force of the
impact. The twisted seat belt routed across
your body could cause injuries.
R Pregnant women should also wear a three-
point seat belt. The lap belt must always
pass across your lap as low down as
possible, i.e. across your hips; not across
your abdomen.
R The seat backrest should be set as close to
vertical as possible.
R Check the seat belt during the journey in
order to make sure that it is correctly
positioned.
R Never rest your feet on the dashboard or
the seat. Always keep both feet on the floor
in front of the seat.
R When using a seat belt to secure an infant
restraint system, child restraint system or
a child on a booster seat, always follow the
child seat manufacturer's instructions. G
WARNING
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 mechanism.
This could damage the seat belt.
Never attempt to make modifications to seat
belts. This could impair the effectiveness of
the seat belts.
Fastening seat belts Important safety notes
G
WARNING
According to accident statistics, children are
safer when properly restrained on the rear
seats than
on the front-passenger seat. Thus,
we strongly recommend that children be
placed in the rear seat whenever possible.
Regardless of seating position, children 12
years old and under must be seated and
properly secured in an appropriately sized
child restraint system or booster seat
recommended for the size and weight of the
child. For additional information, see the
"Children in the vehicle" section.
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. G
WARNING
Children 12 years old and under must never
ride in the front seat, except in a Mercedes-
Benz authorized BabySmart™ compatible
child seat, which operates with the
BabySmart™ system installed in the vehicle
to deactivate
the front passenger front air bag
when it is installed properly. Otherwise they
will be struck by the air bag when it inflates in
a crash. If this happens, serious or fatal injury
will result. Occupant safety

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. Position
the shoulder belt across the chest and
shoulder, not face or neck. A booster seat
may be necessary to achieve proper seat belt
positioning for children over 41 lb (18 kg) 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.
If an infant or child is traveling in the vehicle:
X Secure the infant or child with an
appropriate infant or child restraint
recommended for the child's age and
weight.
X Make sure that the infant or child is
properly secured at all times while the
vehicle is in motion. G
WARNING
When leaving the vehicle, always remove the
SmartKey from the ignition lock. Always take
the SmartKey with you and lock the vehicle.
Do not leave children unattended in the
vehicle, even if they are secured in a child
restraint system, or with access to an
unlocked vehicle. A child's unsupervised
access to
a vehicle could result in an accident
and/or serious personal injury. The children
could:
R injure themselves on parts of the vehicle
R be seriously or fatally injured through
excessive exposure to extreme heat or cold
R injure themselves or cause an accident with
vehicle equipment that can be operated even if the SmartKey is removed from the
ignition lock or removed from the vehicle,
such as seat adjustment, steering wheel
adjustment, or the memory function
If children
open a door, they could injure other
persons or get out of the vehicle and injure
themselves or be injured by following 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. G
WARNING
Do not carry heavy or hard objects in the
passenger compartment
or trunk unless they
are firmly secured in place.
Unsecured or improperly positioned cargo
increases a child's risk of injury in the event
of
R strong braking maneuvers
R sudden changes of direction
R an accident

WARNING
Observe "Important safety notes"
(Y page 47). G
WARNING
Children that are too large for a child restraint
must travel in seats using normal seat belts.
Position shoulder belt across the chest and
shoulder, not face or neck.
In order
to attain the correct seating position
for children weighing over 41 lb (18 kg), it may
be necessary to use a booster seat until they
reach a height where a normal lap/shoulder
seat belt lies properly across their bodies
without the need for a booster seat.
Install the child restraint system according to
the manufacturer's instructions. The child restraint system must be installed
firmly on both brackets.
An
incorrectly
installed child restraint system
can come loose in the event of an accident,
causing the child to be severely or fatally
injured.
Child restraint systems/child restraint
retaining brackets that are damaged or have
suffered damage due to an impact must be
replaced.
ISOFIX is a standardized securing system for
specially designed child restraint systems on
the rear seats. Securing rings for two LATCH-
type (ISOFIX) child restraint systems are
installed on the left and right of the rear seats.
Secure non-LATCH-type (ISOFIX) child
restraint systems using the vehicle's seat belt
system. Always install child restraint systems
according to the manufacturer's instructions. :

Important safety notes G
WARNING
For safety reasons, always drive with the rear
head restraints in the upright position when
the rear seats are occupied.
Keep the
area around head restraints clear of
articles (e.g. clothing) to not obstruct the
folding operation of the head restraints. G
WARNING
For your protection, drive only with properly
positioned head restraints.
Adjust the
head restraint so that it is as close
to the head as possible and the center of the
head restraint supports the back of the head
at eye level. This will reduce the potential 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 intended to
help reduce injuries during an accident.
