77 Safety and Security
Occupant safety
Preventive occupant safety* (PRE-SAFE)
®
Your vehicle automatically takes preven-
tive measures to better protect the occu-
pants in the following hazardous
situations:

You execute an emergency braking
maneuver and the Brake Assist System
(page 95) is activated.


The PRE-SAFE
® system detects a criti-
cal driving dynamics situation.In such cases, the following systems are
automatically activated:


The front seat belts are pre-tensioned
electrically.
Vehicles with front passenger seat
memory function*:


If the OCS senses that the front pas-
senger seat is occupied and the seat is
in an unfavorable position, it will be
adjusted to a better position.
Vehicles with power tilt/sliding sunroof*:


The tilt/sliding sunroof closes if the
vehicle is in a severe skid or is
spinning.If the seat belts do not release:

Adjust the backrest or seat slightly to
the rear until the seat belt tension is di-
minished.
The locking mechanism releases.
Warning!
G
The PRE-SAFE
® system is intended to re-
duce the effects of an accident on properly
seat-belted vehicle occupants. Despite
having the PRE-SAFE
® system in your vehi-
cle, the possibility of injuries occurring as a
result of an accident cannot be eliminated.
Therefore, you should always drive carefully
and adjust your driving to the prevailing
road, weather, and traffic conditions.
iIf the closing procedure of the tilt/slid-
ing sunroof is blocked, the tilt/sliding
sunroof will stop and open slightly.
iThe PRE-SAFE
® system is activated in
the previously described circumstanc-
es only at speeds exceeding 22 mph
(35 km/h).
When the critical driving dynamic situa-
tion has passed without an accident oc-
curring, the pre-tensioning on the seat
belts is deactivated.
You can then adjust the seat and the
tilt/sliding sunroof to their previous
position.

79 Safety and Security
Occupant safety
A statement by the child restraint manu-
facturer of compliance with this standard
can be found on the instruction label on
the restraint and in the instruction manual
provided with the restraint.
When using any infant or child restraint
system, make sure to carefully read and
follow all manufacturer’s instructions for
installation and use.
Please read and observe warning labels af-
fixed to the inside of the vehicle and to
infant or child restraints.Warning!
G
Never release the seat belt buckle while the
vehicle is in motion, since the special seat
belt retractor will be deactivated.
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.
Children can be killed or seriously injured by
an inflating air bag. Note the following im-
portant information when circumstances
require you to place a child in the front
passenger seat:

Your vehicle is equipped with air bag
technology designed to turn off the front
passenger front air bag in your vehicle
when the OCS senses the weight of a
typical 12-month-old child or less along
with the weight of a standard
appropriate child restraint on the front
passenger seat.


A child in a rear-facing child restraint on
the front passenger seat will be serious-
ly injured or even killed if the front
passenger front air bag inflates in a
collision which could occur under some
circumstances, even with the air bag
technology installed in your vehicle. The
only means to completely eliminate this
risk is to never place a child in a rear-fac-
ing child restraint in the front seat. We
therefore strongly recommend that you
always place a child in a rear-facing
child restraint in the back seat.


80 Safety and SecurityOccupant safety

If you must install a rear-facing child
restraint on the front passenger seat be-
cause circumstances require you to do
so, make sure that the
59indicator lamp is illuminat-
ed, indicating that the front passenger
front air bag is deactivated. Should the
59indicator lamp not illumi-
nate or go out while the restraint is in-
stalled, please check installation.
Periodically check the
59indicator lamp while driv-
ing to make sure the lamp is illuminated.
If the 59indicator lamp goes
out or remains out, do not transport a
child on the front passenger seat until
the system has been repaired. A child in
a rear-facing child restraint on the front
passenger seat will be seriously injured
or even killed if the front passenger front
air bag inflates.


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 82).
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.


82 Safety and SecurityOccupant safetyWarning!
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 401).
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 started
and remain illuminated, indicating that the
front passenger front air bag is deactivated.
When the OCS senses that the front passen-
ger seat is classified as being empty, the
59indicator lamp will illuminate
when the engine is started and remain
illuminated, indicating that the front
passenger front air bag is deactivated.
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 illumi-
nate for approximately six 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 deactivated.
With the 59indicator lamp out,
the front passenger front air bag is activat-
ed.
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 illuminate
for approximately six seconds when the en-
gine is started and then go out, indicating
that the front passenger front air bag is
activated.

83 Safety and Security
Occupant safety
If the 59indicator lamp is illumi-
nated, the front passenger front air bag is
deactivated and will not be deployed.
If the 59indicator lamp is not illu-
minated, 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 air bag is deployed,
the rate of inflation will be influenced by:


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


front passenger’s weight category as
identified by the Occupant Classification
System (OCS).

that the seat was occupied by a
small individual (such as a young
teenager or a small adult) or a child
weighing more than the weight of a
typical 12-month-old child in a stan-
dard child restraint - instances
where the system may suppress
deployment of the front passenger
front air bag even though the
impact met the criteria and was of
sufficient severity to deploy the
driver front air bag.
Warning!
G
If the 1indicator lamp and the
59indicator lamp are lit at the
same time, there is a malfunction in the
Occupant Classification System. The front
passenger front air bag will be deactivated
in this case. Have the system checked as
soon as possible by qualified technicians.
Contact an authorized Mercedes-Benz Light
Truck Center.
In order to ensure proper operation of the
air bag system and OCS:

Do not place more than 4.4 lbs (2 kg)
into the ruffled storage bag on the back
of the front passenger seat. Otherwise,
the OCS may not be able to properly
approximate the occupant weight
category.

Self-test Occupant Classification Sys-
tem
After turning the SmartKey in the starter
switch to position1 or2 or pressing the
KEYLESS-GO* start/stop button once or
twice, the 59 indicator lamp1
located in the center console illuminates. If
an adult occupant is properly sitting on the
front passenger seat and the system sens-
es the occupant as being an adult, the
59indicator lamp will illuminate
and go out after approximately
six seconds.
If the seat is not occupied and the system
senses the front passenger seat as being
empty, the 59indicator lamp
will illuminate and not go out.For more information, see the “Practical
hints” section (
page 401).


Do not place objects under and/or
around the front passenger seat.


Do not hang anything from or attach any
items to the seats.


Do not stuff objects such as books be-
tween the middle console and the front
passenger seat.


Do not move the front passenger seat
backwards against stiff objects.


Sit properly belted in a nearly upright
position with your back against the seat
backrest.


Do not lean on the armrests or lift your-
self from the seat by using the handle
over the door as this may cause the OCS
to be unable to correctly approximate
the occupant weight category.


Only have the seat repaired or replaced
by an authorized Mercedes-Benz Light
Truck Center.


Read and observe all warnings in this
chapter.
Warning!
G
If the 59indicator lamp should not
illuminate, the system is not functioning.
You must see an authorized Mercedes-Benz
Light Truck Center before seating any child
on the front passenger seat.Warning!
G
Never place anything between seat cushion
(e.g. pillow), since it reduces the effective-
ness of the Occupant Classification System.
The bottom of the child seat must make full
contact with the passenger seat cushion. An
incorrectly mounted child seat could cause
injuries to the child in case of an accident,
instead of increasing protection for the
child.
Follow the manufacturer’s instructions for
installation of child seats.
