for cargo compartment expansion (
page 284),
the front seats may not be moved to the rear-
most position. Otherwise you could damage the
front and rear seats.

ward.

Warning!
G
Do not drive the vehicle without the seat
head restraints. Head restraints are intend-
ed to help reduce injuries during an
accident.
With a rear seat occupied, make sure to
move the respective head restraint up from
the lowest non-use position and have the
occupant adjust the head restraint properly.
For your protection, drive only with properly
positioned and engaged 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 po-
tential for injury to the head and neck in the
event of an accident or similar situation.!
Do not attempt to remove front seat head
restraints. They can only be removed by qualified
technicians. We recommend that you have this
work carried out by an authorized
Mercedes-Benz Light Truck Center.
53 Getting started
Driving
With a smooth motion, pull the belt out
of seat belt outlet1.
Place the shoulder portion of the belt
across the top of your shoulder and the
lap portion across your hips.
Push latch plate2 into buckle3
(page 52) until it clicks.
If necessary, tighten the lap portion to
a snug fit by pulling shoulder portion
up.
Seat belt height adjustment
1Release button
Press release button1 and move the
seat belt height adjuster upward or
downward.
Proper use of seat belts
Do not twist the belt when fastening.
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 belt under your
arm. For this purpose, you can adjust
the height of the belt outlet
(page 53).
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 or toddler restraints or children
in booster seats, always follow the
child seat manufacturer’s instructions.
Check your seat belt periodically
during travel to make sure that it is
properly positioned.
Make sure the seat belt is always fitted
snugly. Take special care of this when
wearing loose clothing.
85 Safety and Security
Occupant safety
Occupant Classification System
The Occupant Classification System (OCS)
automatically turns the front passenger
front air bag on or off based on the classi-
fied occupant weight category determined
by weight sensor readings from the front
passenger seat.
Occupants must sit properly belted in a
nearly upright position with their back
against the seat backrest and feet on the
floor to be correctly classified. If the occu-
pant’s weight is transferred to another
object in the vehicle (e.g. by leaning on
armrests), the OCS may not be able to
properly approximate the occupant’s
weight category.
If you have to place a child in a
forward-facing child restraint on the
front passenger seat, move the seat as
far back as possible, use the proper
child restraint recommended for the
age, size and weight of the child, and se-
cure child restraint with the vehicle’s
seat belt according to the child seat
manufacturer’s instructions. For
children larger than the typical
12-month-old child, the front passenger
front air bag may or may not be
activated (
page 86).
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/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. Posi-
tion shoulder belt across chest and shoul-
der, not face or neck. A booster seat may be
necessary to achieve proper belt positioning
for children from 41 lbs 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.
Do not leave children unattended in the
vehicle, even if the children are secured in a
child restraint system. Unsupervised chil-
dren in a child restraint system may use
vehicle equipment and may cause an acci-
dent and/or serious personal injury.
i
The system does not deactivate the front
passenger side impact air bag, the window
curtain air bag, and the emergency tensioning
device.

hicle, even if the children are secured in a
