Warning!G
When occupants have entered or exited the
vehicle using the easy-entry/exit feature,
before driving off make sure

the seats are properly locked

the seat backrests are in an upright po-
sition and are properly locked
If a seat and seat backrest are not properly
locked, the seat could move forward and the
seat backrest could fold. You could slide un-
der the seat belt during braking, vehicle ma-
neuvers, or in an accident. If you slide under
it, the belt would apply force at the abdomen
or neck. That could cause serious or even fa-
tal injuries.
iIf, due to an accident or other situation, it is
not possible for you to exit the vehicle on the
side of the easy-entry seat (
page 130), you
can fold the left side of the seat backrest in the
second row of seats down in order to open the
left rear door.
!Make sure that the head restraint is pushed
all the way down (
page 135).

Front seat active head restraints
You cannot remove the active head
restraints on the driver’s and front
passenger’s seat.
For removal of the active head restraints
we recommend that you contact an
authorized Mercedes-Benz Light Truck
Center.
For information on head restraint adjust-
ment, see “Seats” (
page 45).
For information on active head restraints,
see “Active head restraint” (
page 90).
Rear seats
Warning!G
To help avoid personal injury when folding
the seat backrest forward, make sure that
you move both feet and legs all the way back
and out of the way to avoid them contacting
the seat as it pivots forward.
In order to prevent an accident or any other
potentially dangerous situations when open-
ing the rear door and exiting the vehicle,
make sure that you are aware of the traffic
situation at all times.
Warning!G
For your protection, drive only with properly
positioned head restraints.
Adjust the head restraint so that it is 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.
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.
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” (
page 91).
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.

Rear seat adjustment
Seat backrest tilt (second-row seats)The seat backrest tilt can be set to five
different positions.
The handles for adjusting the seats are
located on the rear of each seat base.
1Adjustment handle
While seated, pull handle1 in direc-
tion of arrow to resistance point and
hold it there.
To move seat backrest back, lean light-
ly against backrest.
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 belt would apply force at the ab-
domen 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
belts are properly positioned on the body.
Your seat must be adjusted so that you can
correctly fasten your seat belt (
page 53).
Never place hands under the seat or near
any moving parts while a seat is being
adjusted.
After adjusting rear seats, make sure

the seats are properly locked

the seat backrests are in an upright po-
sition and are properly locked
Check for secure locking by pushing and
pulling on the seat backrests. If a seat and
seat backrest are not properly locked, the
seat could move forward and the seat back-
rest could fold. The child seat would no long-
er be properly supported or positioned to
provide its intended benefit.
Warning!G
The seat belt only offers its intended protec-
tion when the seat backrest is in a nearly
vertical position and the occupant is sitting
upright. Avoid sitting in positions that pre-
vent the seat belt from being properly posi-
tioned against the body (
page 53). You
should therefore adjust the backrest to a po-
sition as upright as possible.
