34 Getting startedAdjusting
AdjustingSeats
Depending on the vehicle’s equipment,
you can adjust the seats manually or elec-
trically.Warning!
G
All seat, head restraint, steering wheel, and
rear view mirror adjustments, as well as fas-
tening of seat belts, must be done before
the vehicle is put into motion.Warning!
G
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 ride in a moving vehicle with the seat
back reclined. Sitting in an excessively re-
clined position 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 abdomen or neck.
That could cause serious or fatal injuries.
The seat back and seat belts provide the
best restraint when the wearer is in an up-
right position and belts are properly posi-
tioned on the body. Your seat must be
adjusted so that you can correctly fasten
your seat belt (
page 40).
Never place hands under the seat or near
any moving parts while a seat is being ad-
justed.
Warning!
G
When leaving the vehicle always remove the
key from the steering lock and lock your ve-
hicle.
Do not leave children unattended in the ve-
hicle or with access to an unlocked vehicle.
Unsupervised use of vehicle equipment may
cause an accident and/or serious personal
injury.
Warning!
G
Children 12 years old and under must never
ride in the front seat, except in a
Mercedes-Benz authorized BabySmart
TM
compatible child seat, which operates with
the BabySmart
TM system installed in the ve-
hicle to deactivate the passenger side front
airbag when it is properly installed. Other-
wise they will be struck by the airbag when
it inflates in a crash. If this happens, serious
or fatal injury will result.
According to accident statistics, children
are safer when properly restrained in the
rear seating positions than in the front seat-
ing positions. Infants and small children
must ride in back seats and be seated in an
appropriate infant or child restraint system,
which is properly secured with the vehicle's
seat belt and top tether strap, or secured via
lower anchors and top tether strap, fully in
accordance with the child seat manufactur-
er’s instructions.

40 Getting startedDriving
DrivingFastening the seat beltsWarning!
G
Do not lay any objects in the driver’s foot-
well. Be careful that floor mats or carpets in
the driver’s footwell have sufficient clear-
ance for the pedals.
During sudden driving or braking maneuvers
the objects could get caught between the
pedals. You could then no longer brake or
accelerate.Warning!
G
Always fasten your seat belt before driving
off. Always make sure your passengers are
properly restrained, even those sitting in the
rear and pregnant women.
Failure to wear and properly fasten and po-
sition your seat belt greatly increases your
risk of injuries and their likely severity in an
accident. You and your passengers should
always wear seat belts.
If you are ever in an accident, your injuries
can be considerably more severe without
your seat belt properly buckled. Without
your seat belt buckled, you are much more
likely to hit the interior of the vehicle or be
ejected from it. You can be seriously injured
or killed.
In the same crash, the possibility of injury or
death is lessened if you are wearing your
seat belt. The airbags can only protect as ex-
pected if the occupants are using their seat
belts (
page 54).
Warning!
G
Children 12 years old and under must never
ride in the front seat, except in a
Mercedes-Benz authorized BabySmart
TM
compatible child seat, which operates with
the BabySmart
TM system installed in the ve-
hicle to deactivate the passenger front air-
bag when it is properly installed. Otherwise
they will be struck by the airbag when it in-
flates in a crash. If this happens, serious or
fatal injury will result.
According to accident statistics, children
are safer when properly restrained in the
rear seating positions than in the front seat-
ing positions. Infants and small children
must ride in back seats and be seated in an

54 Safety and SecurityOccupant safety
Occupant safetyIn this section you will learn the most im-
portant facts about the restraint systems
of the vehicle.
The restraint systems are

Seat belts


Emergency tensioning device


Airbags


Child seats


Child seat recognition


Lower anchors and tethers for children
(LATCH)
As independent systems their protective
effects work in conjunction with each oth-
er.The warning lamp
1
in the instrument
cluster (
page 26) lights up for about
4 seconds when the key is turned to
position2. It goes out when you start the
engine. This shows that the restraint sys-
tems are operational.
If the lamp does not come on at all or if it
fails to extinguish after approximately
4 seconds or if it comes on thereafter, a
malfunction in the system has been de-
tected.
More information can be found in the
“Practical hints” section (
page 227).
iFor information on infants and children
traveling with you in the vehicle and re-
straint systems for infants and chil-
dren, see “Children in the vehicle”
(page 63).
Warning!
G
In the event that the SRS malfunction indica-
tor lamp lights up during driving or does not
come at all, the SRS may not be operational.
For your safety, we strongly recommend
that you visit an authorized Mercedes-Benz
Light Truck Center immediately to have the
system checked; otherwise the SRS may not
be activated when needed in an accident,
which could result in serious or fatal injury,
or it might deploy unexpectedly and unnec-
essarily which could also result in injury.
Improper work on the restraint systems can
lead to unintentional deployment or opera-
tional failure.
All work on these systems should therefore
only be carried out by an authorized
Mercedes-Benz Light Truck Center.

belt retractor will be deactivated.!The use of infant or child restraints is
required by law in all 50 states, the
District of Columbia, the U.S. territo-
ries and all Canadian provinces.
Infants and small children should be
seated in an appropriate infant or child
restraint system properly secured by a
lap-shoulder belt or, if so equipped, a
child restraint lower anchorage system
that complies with U.S. Federal Motor
Vehicle Safety Standards 213 and 225
and Canadian Motor Vehicle Safety
Standard 213 and 210.2. A statement
by the child restraint manufacturer of
compliance with this standard can be
found on the instruction label on the re-
straint and in the instruction manual
provided with the restraint.
When using any infant or child restraint
system, be sure to carefully read and
follow all manufacturer’s instructions
for installation and use.
Please read and observe warning labels
affixed to inside of vehicle and to infant
or child restraints.

68 Safety and SecurityOccupant safety

When using the center second row seat
for a top tether strap, the left third row
seat should only be used for a child re-
straint system, since exiting the vehicle
may not be possible in an emergency
due to the routing of the top tether
strap.


When installing an infant or child re-
straint system with a top tether strap
on the left second row seat, the left
third row seat should not be occupied. Child seat anchors – “LATCH” type
This vehicle is provided with two “LATCH”
(LOWER Anchors and Tethers for CHil-
dren) type anchors (at each of the outer
rear seats and in the optional third row
seats) for installation of a “LATCH” seat
with matching mounting fittings.
1Anchors

Install a “LATCH” type child seat ac-
cording to the manufacturer’s instruc-
tions.
!An infant and child restraint system
must not be installed on the right
second row seat while a passenger
rides in a third row seat. An infant and
child restraint system installed on the
right second row seat will prevent the
use of the easy-entry/exit feature
(page 95).
iWith a child seat installed in the left
rear seat, the seat belt for the center
seat occupied by a passenger must op-
erate freely. Guide seat belt between
its seat cushion mount and backrest
