Seats
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
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 position that is as upright as
possible and belts are properly positioned
on the body.
Warning!G
Your seat must be adjusted so that you can
correctly fasten your seat belt (
page 54).
Observe the following points:

Adjust the backrest until your arms are
slightly angled when holding the steer-
ing wheel

Adjust the seat to a comfortable seating
position that still allows you to reach the
accelerator/brake pedal safely. The po-
sition should be as far back as possible
with the driver still able to operate the
controls properly.

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.

Never place hands under the seat or
near any moving parts while a seat is be-
ing adjusted.
Failure to do so could result in an accident
and/or serious personal injury.
Warning!G
When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock the vehicle.
Even with the SmartKey or the SmartKey
with KEYLESS-GO* removed from the
starter switch or the SmartKey with
KEYLESS-GO* removed from the vehicle,
the power seats can be operated when the
respective door is open.
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.

Warning!G
Vehicles with BabySmartTM air bag deactiva-
tion system, Canada only:
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
vehicle to deactivate the front passenger
front air bag when it is properly installed.
Otherwise they will be struck by the air bag
when it inflates in a crash. If this happens,
serious or fatal injury will result.
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
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 addi-
tional information, see “Children in the vehi-
cle” (
page 93).
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.

49 Getting started
Adjusting
Head restraint fore and aft adjustment
Manually adjust the angle of the head
restraint.
While seated, reach behind you with
both hands and find lower edge of the
head restraint.
Adjust the head restraint to the desired
position by pushing or pulling on the
lower edge of the head restraint cush-
ion.
For more information, see “Seats”
(
page 132).
Steering wheel
Easy-entry/exit feature*
This feature allows for easier entry into and
exit from the vehicle. When entering and
exiting the vehicle, the steering wheel is in
its uppermost position.
The easy-entry/exit feature can be
activated or deactivated in the
Comfort
submenu of the control system
(
page 184).With the easy-entry/exit feature activated,
the steering wheel will return to its last set
position when you:

close the driver’s door with the ignition
switched on
or

insert the SmartKey into the starter
switch or press the KEYLESS-GO*
start/stop button (
page 43) once
with the driver’s door closed
Warning!G
You must make sure no one can become
trapped or injured by the moving steering
wheel when the easy-entry/exit feature is
activated.
To stop steering wheel movement, do one of
the following:

Move steering wheel adjustment stalk*
(
page 52).

Press one of the memory position
buttons or memory buttonM*
(
page 144).
Do not leave children unattended in the ve-
hicle, or with access to an unlocked vehicle.
Children could open the driver’s door and
unintentionally activate the easy-entry/exit
feature, which could result in an accident
and/or serious personal injury.

seat belt provide the best restraint when the
wearer is in a position that is as upright as
possible and the belt is properly positioned
on the body.
Warning!G
Never let more people ride in the vehicle
than there are seat belts available. Make
sure everyone riding in the vehicle is cor-
rectly restrained with a separate seat belt.
Never use a seat belt for more than one per-
son at a time.
Warning!G
Read and observe the additional warning no-
tices printed in the “Safety and Security”
section (
page 78) and (page 88).

57 Getting started
Driving

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.
Starting the engine
Warning!G
Do not pass belts over sharp edges. They
could tear.
Do not allow the belt to get caught in the
door or in the seat adjustment mechanism.
This could damage the belt.
Never attempt to make modifications to
seat belts. This could impair the effective-
ness of the belts.
Do not bleach or dye seat belts as this may
severely weaken them. In a crash, they may
not be able to provide adequate protection.
Damaged seat belts or belts that were highly
stressed in an accident must be replaced.
Contact an authorized Mercedes-Benz Light
Truck Center.Warning!G
Inhalation of exhaust gas is hazardous to
your health. All exhaust gas contains carbon
monoxide (CO), and inhaling it can cause un-
consciousness and possible death.
Do not run the engine in confined areas
(such as a garage) which are not properly
ventilated. If you think that exhaust gas
fumes are entering the vehicle while driving,
have the cause determined and corrected
immediately. If you must drive under these
conditions, drive only with at least one win-
dow fully open.

74 Safety and Security
Occupant safety
In this section you will learn the most im-
portant facts about the restraint systems
of the vehicle.
The restraint systems are

Canada only:
Front passenger seat with
BabySmart
TM air bag deactivation
system (
page 87)
Although independent systems, their
protective functions work in conjunction
with each other.The SRS system conducts a self-test when
the ignition is switched on and in regular
intervals while the engine is running. This
facilitates early detection of malfunctions.
The
1indicator lamp in the instrument
cluster (
page 26) comes on when the
ignition is switched on and goes out no
later than a few seconds after the engine
was started.
The SRS components are in operational
readiness if the
1indicator lamp is not
lit when the engine is running.
A malfunction in the system has been
detected if the
1indicator lamp:

fails to go out not later than approxi-
mately 4 seconds after the engine was
started

does not come on at all

comes on after the engine was started
or while driving

77 Safety and Security
Occupant safety

Always sit as upright as possible, prop-
erly use the seat belts and use an appro-
priately sized infant restraint, toddler
restraint, or booster seat recommended
for the size and weight of the child.

Vehicles with BabySmartTM air bag
deactivation system, Canada only:
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 BabySmartTM
system installed in the vehicle to deacti-
vate the front passenger front air bag
when it is properly installed. Otherwise
they will be struck by the air bag when it
inflates in a crash. If this happens, seri-
ous or fatal injury will result.
Failure to follow these instructions can
result in severe injuries to you or other
occupants.
If you sell your vehicle, it is important that
you make the buyer aware of this safety
information. Be sure to give the buyer this
Operator’s Manual.
Warning!G
Accident research shows that the safest
place for children in an automobile is in the
rear seat.
It should be noted that with respect to both,
front side impact air bags or the rear side
impact air bags*, there is a possibility for a
side impact air bag related injury if occu-
pants, especially children, are not properly
seated or restrained when next to a side
impact air bag which needs to deploy rapidly
in a side impact in order to do its job.
To help avoid the possibility of injury, please
follow these guidelines:
(1) Always sit as upright as possible,
properly use the seat belts, and for all
children 12 years old and under, use an
appropriately sized infant restraint,
toddler restraint, or booster seat recom-
mended for the size and weight of the
child.
(2) Always wear seat belts properly.
iAir bags are designed to deploy only in
certain frontal impacts (front air bags), and in
side impacts (side impact and window curtain air
bags) which exceed preset thresholds, and in
certain rollovers (window curtain air bags). Only
during these events will they provide their sup-
plemental protection.
The driver and passengers should always wear
their seat belts. Otherwise it is not possible for
air bags to provide their supplemental protec-
tion.
In case of other types of impacts and impacts be-
low air bag deployment thresholds, air bags will
not deploy. The driver and passenger will then be
protected to the extent possible by a properly
fastened seat belt. A properly fastened seat belt
is also needed to provide the best possible pro-
tection in a rollover.
We caution you not to rely on the presence of the
air bags in order to avoid wearing your seat belt.
It is important to your safety and that of your pas-
sengers that you replace deployed air bags and
repair any malfunctioning air bags to make sure
the vehicle will continue to provide supplemental
crash protection for occupants.

82 Safety and Security
Occupant safety
Furthermore, the occupant weight may ap-
pear to increase or decrease due to
objects hanging on the seat, other passen-
gers pushing on the seat, objects lodged
underneath the seat or stuffed between
seat and middle console or between seat
and door or due to objects applying pres-
sure on the back of the seat. Always make
sure that the seat has clearance in all
directions at all times.
Both, driver and the front passenger
should always use the
59indicator lamp as an indi-
cation of whether or not the front passen-
ger is properly positioned.
iIf your seat, including your trim cover and
cushion needs to be serviced in any way, take
the vehicle to an authorized Mercedes-Benz
Light Truck Center.
Only seat accessories approved by
Mercedes-Benz may be used.
Warning!G
If the 59indicator lamp illumi-
nates when an adult or someone larger than
a small individual is in the front passenger
seat, have the front passenger re-position
himself or herself in the seat until the
59indicator lamp goes out, or
check whether objects are caught under or
around the seat.
More information about air bag display mes-
sages (
page 463).
In the event of a collision, the air bag control
unit will not allow front passenger front air
bag deployment when the OCS classified
the front passenger seat occupant as being
up to or less than the weight of a typical
12-month-old child in a standard child re-
straint or if the front passenger seat is
sensed as being empty.
When the OCS senses that the front passen-
ger seat occupant is classified as being up
to or less than the weight of a typical
12-month-old child in a standard child
restraint, the 59indicator
lamp will illuminate when the engine is start-
ed and remain illuminated, indicating that
the front passenger front air bag is deacti-
vated.
When the OCS senses that the front passen-
ger seat is classified as being empty, the
59indicator lamp will illumi-
nate when the engine is started and remain
illuminated, indicating that the front
passenger front air bag is deactivated.

83 Safety and Security
Occupant safety
When the OCS senses that the front passen-
ger seat occupant is classified as being
heavier than the weight of a typical
12-month-old child seated in a standard
child restraint or as being a small individual
(such as a young teenager or a small adult),
the 59indicator lamp will illu-
minate for approximately 6 seconds when
the engine is started and then, depending on
occupant weight sensor readings from the
seat, remain illuminated or go out. With the
59indicator lamp illuminated,
the front passenger front air bag is deacti-
vated. With the 59indicator
lamp out, the front passenger front air bag is
activated.
When the OCS senses that the front passen-
g e r s e a t o c c u p a n t i s c l a s s i f i e d a s a n a d u l t o r
someone larger than a small individual, the
59indicator lamp will illumi-
nate for approximately 6 seconds when the
engine is started and then go out, indicating
that the front passenger front air bag is
activated.If the 59indicator lamp is illu-
minated, the front passenger front air bag is
deactivated and will not be deployed.
If the 59indicator lamp is not
illuminated, the front passenger front air
bag is activated and will be deployed:

in the event of certain frontal impacts

if impact exceeds a preset deployment
threshold

independently of the side impact air
bags.
If the front passenger front air bag is de-
ployed, the rate of inflation will be influ-
enced by:

the rate of vehicle deceleration as
assessed by the air bag control unit

the front passenger’s weight category
as identified by the Occupant Classifica-
tion System (OCS)
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
whenever possible. Regardless of seating
position, children 12 years old and under
must be seated and properly secured in an
appropriate infant or child restraint
recommended for the size and weight of the
child.
The infant or child restraint must be properly
secured with the vehicle’s seat belt, the seat
belt and top tether strap, or lower anchors
and top tether strap, fully in accordance
with the child seat manufacturer’s
instructions.
