Seats
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 54).
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 54). You
should therefore adjust the backrest to a po-
sition as upright as possible.

Automatic transmission
Effect
ìPark position
Shift into park positionP only
when vehicle is stopped. The
park position is not intended to
serve as a brake when the vehi-
cle is parked. Rather, the driver
should always set the parking
brake in addition to shifting into
park positionP to secure the
vehicle.
If the vehicle’s electrical system
is malfunctioning, the automatic
transmission could remain
locked in park positionP.
Have the vehicle checked as
soon as possible by an autho-
rized Mercedes-Benz Light
Truck Center.
!SmartKey:
If you turn off the engine using the SmartKey and
remove the SmartKey from the starter switch,
the transmission will shift to park positionP
automatically. Keep in mind that turning off the
engine with the SmartKey alone will not automat-
ically shift the transmission to park positionP.
!KEYLESS-GO*:
If you turn off the engine using the KEYLESS-GO*
start/stop button and open a front door, the
transmission will shift to park positionP
automatically. Keep in mind that turning off the
engine using the KEYLESS-GO* start/stop
button alone will not automatically shift the
transmission to park positionP.
iEven though this is possible, make it a prac-
tice to always shift into park positionP before
turning off the engine and remove the SmartKey
from the starter switch, or when using
KEYLESS-GO*, before turning off the engine with
the start/stop button and opening a front door.
Effect
íReverse gear
Shift into reverse gearR only
when the vehicle is stopped.
ëNeutral
No power is transmitted from the
engine to the drive axle. When
the brakes are released, the

To avoid damage to the transmis-
sion, never shift into neutral
positionN while driving.
If the ESP
® is deactivated or
malfunctioning:
Shift into neutral positionN only
if the vehicle is in danger of
skidding, e.g. on icy roads.

Installing the basic cross bars
iSpare parts are available as Mercedes-Benz
accessories. Contact your authorized
Mercedes-Benz Light Truck Center.
Warning!G
Please follow these installation instructions
carefully. Caution should be exercised to
avoid damage to the vehicle while installing
the basic cross bars. Also, be careful not to
injure yourself or others while installing and
adjusting the basic cross bars or loading
items on them.
Each individual step of the installation in-
structions, the warning notices, the general
safety precautions and the instructions for
use must be followed exactly. If the basic
cross bars are not mounted correctly, they
and the objects attached to them could
come loose from your vehicle and cause an
accident, thereby injuring you and other per-
sons and/or causing damage to property,
including damage to your vehicle.
Warning!G
Every time the basic cross bars are mount-
ed, before you set off on a journey and peri-
odically during longer journeys, check all the
screws on the bars to make sure that they
are secure, and tighten them if necessary.
Repeat these checks at regular intervals as
road-surface conditions dictate, and at least
after every 1500 miles (2500 km) of contin-
uous use.
Otherwise, the basic cross bars, mounted
accessories and the objects attached to
them could come loose from the vehicle
causing an accident, thereby injuring you
and other persons and/or causing damage
to property, including damage to your vehi-
cle.
Do not use lubricant on the screws of the
basic cross bars. The screws could work
loose and the basic cross bars could be-
come detached from your vehicle, together
with the objects attached to them causing
an accident, thereby injuring you and other
persons and/or causing damage to proper-
ty, including damage to your vehicle.
Warning!G
Only install the basic cross bars at the exact
locations designated on the roof rails. The
designated locations for the front basic
cross bars are between the markings en-
graved on the inside of the roof rails
(
page 300). The designated locations for
the rear basic cross bars are between the
gaps on the roof rails (
page 300).

Warning!G
Always fasten items being carried as secure-
ly as possible using cargo tie-down rings and
fastening materials appropriate for the
weight and size of the load.
In an accident, during hard braking or sud-
den maneuvers, loose items will be thrown
around inside the vehicle, and can cause in-
jury to vehicle occupants unless the items
are securely fastened in the vehicle.
To help avoid personal injury during a colli-
sion or sudden maneuver, always use tie
down rings, and if so equipped, always use
the cargo net* when transporting cargo.
Never drive vehicle with the tailgate open.
Deadly carbon monoxide (CO) gases may
enter vehicle interior resulting in uncon-
sciousness and death.
