Second-row middle seat G
Warning!
Only install a child seat in the second-row
middle seat position if the outboard seat belt
buckle is not obstructed or overlapped by the
child seat. Not all child seats, including some
Mercedes-Benz approved child seats, can be
used in this seating position. Contact an
authorized Mercedes-Benz Center for more
information.
Do not use the LATCH anchors or seat belt
buckle for the outboard seats in conjunction
with a child seat in the second-row middle
seat position. Child seats in the middle
seating position must only be secured by the
middle seat position seat belt inserted into the seat belt buckle for the second-row
middle seat.
G
Warning!
Please be aware that installation of a child
seat in the second-row middle seat position
can prevent the folding forward of the
outboard second-row seats which can
obstruct access to and exit from the third-row
seats. In case of an accident it will be difficult
for occupants of the third-row seats to leave
the vehicle. Serious injuries could result.
Install a child seat in one of the outboard
seating positions according to the installation
instructions if access to the third-row seats is
required.

Child seat anchors – LATCH-type G
Observe Safety notes, see page 55. G
Warning!
Children too big for a toddler restraint must
ride in seats using regular seat belts. Position
shoulder belt across 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.
Install child seat according to manufacturer’s
instructions.
The child seat must be firmly attached to both
anchors.
An incorrectly mounted child seat may come
loose during an accident which could result in
serious injury or death to the child.
Damaged or impact damaged child seats or
child seat mounting fittings must be replaced.
Each of the outboard second-row seats and
third-row seats has two LATCH-type anchors
for the installation of a LATCH-type child seat
with matching mounting fittings.
Non-LATCH-type child seats may also be used
and can be installed using the vehicle’s seat
belt system. Install child seat according to the
manufacturer’s instructions. 60

R
Adjust the head restraint so that it is as
close
to the head as possible. The center of
the head restraint must support 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. G
Warning!
The power 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. G
Warning!
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. 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.
Seat adjustment
! When moving the seats, make sure there
are no items in the footwell or behind the
seats. Otherwise, you could damage the
seats and/or the items.
Power seats !
When the second-row seats are folded
forward, e.g. for cargo volume expansion,
the front seats may not be moved to the
rearmost position. Otherwise you could
damage the front and second-row seats.
! When
adjusting the seat backrest tilt and
head restraint height, make sure the sun
visor is folded up. If the head restraint is in
the uppermost position, it could hit and
damage the sun visor.
i Vehicles without memory function:
The seats can be adjusted within 5 minutes
after either front door has been opened.
The counter resets each time
R you open or close a front door
R you insert the SmartKey into the starter
switch
R you remove the SmartKey from the
starter switch
R you switch the ignition on or off
Just like in vehicles with memory function,
the power seats can be operated at any
time when the ignition is switched on.
i The memory function (Y page 96) lets
you store the settings for the seat position
together with the settings for the steering
wheel (electrical) and exterior rear view
mirrors. 82

Rear seat adjustment G
Warning!
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 serious
or fatal injuries. The seat backrest and seat
belts provide the best restraint when the
wearer is in a nearly upright position and seat
belts are properly positioned on the body.
Your seat must be adjusted so that you can
correctly fasten your seat belt.
Never place hands under the seat or near any
moving parts while a seat is being adjusted.
After adjusting rear seats, make sure
R the seats are properly locked
