system, child restraint system or booster seat
suitable for the size and weight of the child.
Children can be seriously or even fatally
injured by an air bag deploying. Observe the
following important information if it is
absolutely necessary to carry a child on the
front-passenger seat:
R USA only: Your vehicle is equipped with air
bag technology that is designed to
deactivate the front-passenger front air
bag, when the system on the front-
passenger seat detects the weight of a
typical 12-month old child in a standard
child restraint.
R USA only: For children that weigh more
than a typical 12-month old child, the front-
passenger front air bag can be activated or
deactivated. Always make sure that the
45 indicator lamp is illuminated
indicating that the front-passenger front air
bag is deactivated.
R Canada only: Children 12 years old and
under may ride on the front seat if a
BabySmart™ compatible child restraint
system is installed on the front-passenger
seat. Use only Mercedes-Benz approved
BabySmart™ compatible child restraint
systems. A BabySmart™ compatible child
restraint system will deactivate the front-
passenger front air bag when installed
correctly. The front-passenger front air bag
will not be deactivated if the child restraint
systems that are installed are not
BabySmart™ compatible or if BabySmart™
compatible child restraint systems are not
installed correctly. If the front-passenger
front air bag is deployed in a collision, the
child could be struck by the air bag. This
could lead to serious or fatal injury.
R 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 vehicle. The only way to completelyrule out this risk is by making sure you
never place a child in a rearward-facing
child restraint system on the front-
passenger seat. For this reason, we
strongly advise that you always carry
children in a rearward-facing child restraint
system on a rear seat.
R If you must install a rear-facing child
restraint on the front-passenger seat
because circumstances require you to do
so, make sure the 45 indicator lamp
is illuminated, indicating that the front-
passenger front air bag is deactivated. If the
45 indicator lamp does not light up
or goes out when the child restraint system
is installed, check the anchorages of the
restraint system. Check the 45
indicator lamp regularly while driving to
ensure that the 45 indicator lamp is
illuminated. If the 45 indicator lamp
goes out or remains out, you may only carry
a child on the front-passenger seat once
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.
R when securing a child in a child restraint
system on the front-passenger seat, you
must:
- move the front-passenger seat as far
back as possible
- use a child restraint system that is
suitable for the age, size and weight of
the child
- observe the manufacturer's installation
instructions in order to install and secure
the child restraint system correctly.GWarning
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.

Seats
Important safety notes
GWarning
In order to avoid possible loss of vehicle
control, all seat, head restraint, steering
wheel and rear view mirror adjustments, as
well as fastening of seat belts, must be done
before setting the vehicle in motion.
GWarning
Do not adjust the driver's seat while driving.
Adjusting the seat while driving could cause
the driver to lose control of the vehicle.
Never travel 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. This could cause serious or
fatal injuries. The seat backrest and seat belts
provide the best restraint when the wearer is
in a position that is as upright as possible and
seat belts are properly positioned on the
body.
GWarning
Your seat belt must be adjusted so that you
can correctly fasten your seat belt.
Observe the following points:
R adjust the seat backrest until your arms are
slightly angled when holding the steering
wheel.
R adjust the seat to a comfortable seating
position that still allows you to reach the
accelerator/brake pedal safely. The
position should be as far back as possible
with the driver still able to operate the
controls properly.
R 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.
R never place hands under the seat or near
any moving parts while a seat is being
adjusted.
Failure to do so could result in an accident
and/or serious personal injury.GWarning
The electrically adjustable seats can be
operated at any time. 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 result
in an accident and/or serious personal injury.
GWarning!
According to accident statistics, children are
safer when properly restrained in the rear
seating positions than in the front seating
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 additional
information, see "Children in the vehicle".
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.
GWarning
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.
! To avoid damage to the seats and the seat
heating, observe the following information:
Rdo not spill any liquids on the seats. If
liquid is spilled on the seats, dry them as
soon as possible.
Rif the seat covers are damp or wet, do not
switch on the seat heating. The seat
heating should also not to be used to dry
the seats.
Rclean the seat covers as recommended;
see the " Interior care" section.
Rdo not transport heavy loads on the
seats. Do not place sharp objects on the
seat cushions, e.g. knives, nails or tools.
The seats should only be occupied by
passengers, if possible.
Rwhen the seat heating is in operation, do
not cover the seats with insulating
materials, e.g. covers, bags, seat covers,
child seats or booster seats.
! When you move the seats, make sure that
there are no objects in the footwell or
behind the seats. Otherwise, you could
damage the seats and the objects.
iThe head restraints in the front seats are
installed with the NECK-PRO system
(Y page 52). For this reason, it is not
possible to remove the head restraints
from the front seats.
