GWARNING
If the restraint system is malfunctioning,
restraint system components may be trig-
gered unintentionally or may not deploy as
intended during an accident. This can affect
for example the Emergency Tensioning
Device or the air bag. This poses an increased
risk of injury or even fatal injury.
Have the restraint system checked and
repaired in a qualified specialist workshop as
soon as possible.
PASSENGER AIR BAG OFF indicator
lamp
PASSENGER AIR BAG OFF indicator lamp :is
part of the Occupant Classification System
(OCS).
The PASSENGER AIR BAG OFF indicator lamp
informs you about the status of the front-
passenger front air bag.
If the PASSENGER AIR BAG OFF indicator
lamp:
Ris lit: the front-passenger front air bag is
deactivated. It will then not be deployed in the
event of an accident.
Ris not lit : the front-passenger front air bag is
enabled. If, in the event of an accident, all
deployment criteria are met, the front-
passenger front air bag is deployed. Depending on the person in the front-passenger
seat, the front-passenger front air bag must
either be deactivated or enabled; see the fol-
lowing points. You must make sure of this both
before and during a journey.
RChildren in a child restraint system:
whether the front-passenger front air bag is
enabled or deactivated depends on the instal-
led child restraint system, and the age and
size of the child. Therefore, be sure to observe
the notes on the "Occupant Classification
System (OCS)" (
Ypage 52) and on "Chil-
dren in the vehicle" (Ypage 58). There you
will also find instructions on rearward and
forward-facing child restraint systems on the
front-passenger seat.
RAll other persons:
depending on the classi-
fication of the person in the front-passenger
seat, the front-passenger front air bag is ena-
bled or deactivated (
Ypage 52). Be sure to
observe the notes on "Seat
belts“ (
Ypage 46) and "Air bags"
(Ypage 49). There you can also find infor-
mation on the correct seat position.
Seat belts
Introduction
Seat belts are the most effective means of
restricting the movement of vehicle occupants
in the event of an accident or the vehicle rolling
over. This reduces the risk of vehicle occupants coming into contact with parts of the vehicle
interior or being ejected from the vehicle. Fur-
thermore, the seat belt helps to keep the vehicle
occupant in the best position in relation to the
air bag.
The seat belt system comprises:
RSeat belts
REmergency Tensioning Devices for the front
seat belts
The seat belt system also includes a seat belt
force limiter for the relevant seat if the vehicle
is equipped with a front air bag.
If the seat belt is pulled out of the belt outlet
quickly or with a jerky movement, the belt
retractor locks. The belt strap cannot be extrac-
ted any further.
The Emergency Tensioning Device tightens the
seat belt in an accident, pulling the belt close
against the body. However it does not pull the

All seat belts except the driver's seat belt are
equipped with a special seat belt retractor to
securely fasten child restraint systems in the
vehicle. Further information can be found under
"Special seat belt retractor" (
Ypage 59).
Releasing seat belts
!Make sure that the seat belt is fully rolled up.
Otherwise, the seat belt or belt tongue will be
trapped in the door or in the seat mechanism.
This could damage the door, the door trim
panel and the seat belt. Damaged seat belts
can no longer fulfill their protective function
and must be replaced. Visit a qualified spe-
cialist workshop.
XPress the release button in the belt buckle,
hold the belt tongue firmly and guide the belt
back.
Belt warning for drivers and front
passenger
The 7 seat belt warning lamp in the instru-
ment cluster is a reminder that all vehicle occu-
pants must wear their seat belts. It may light up continuously or flash. In addition, there may be
a warning tone.
Regardless of whether the driver's seat belt has
already been fastened, the 7seat belt warn-
ing lamp lights up for six seconds each time the engine is started. If the front doors are closed
and the driver's or front-passenger seat belt has
not been fastened, the 7seat belt warning
lamp lights up again after the six seconds. As
soon as the driver's and front-passenger seat
belts are fastened or a front door is opened
again, the 7seat belt warning lamp goes out.
If the driver's seat belt is not fastened when the engine is started, an additional warning tone will
sound. This warning tone stops after a maximum
of six seconds or once the driver's seat belt is
fastened.
If the vehicle's speed exceeds 15 mph
(25 km/h) once and the driver's and front-
passenger seat belts are not fastened, a warning
tone sounds. A warning tone also sounds with
increasing intensity for 60 seconds or until the
driver or front passenger have fastened their
seat belts.
If the driver or front passenger unfasten their
seat belts during the journey, the seat belt warn-
ing is activated again.
Air bags
Introduction
The installation point of an air bag can be rec-
ognized by the AIRBAG marking.
An air bag complements the correctly fastened
seat belt. It is no substitute for the seat belt. The
air bag provides additional protection in appli-
cable accident situations.
Not all air bags are deployed in an accident. The
different air bag systems function independ-
ently from one another (
Ypage 56).

GWARNING
If you secure a child in a forward-facing child
restraint system on the front-passenger seat
and you position the front-passenger seat too close to the dashboard, the child could, in the
event of an accident:
Rcome into contact with the vehicle's inte-
rior if the PASSENGER AIR BAG OFF indi-
cator lamp is lit, for example
Rbe struck by the air bag if the PASSENGER
AIR BAG OFF indicator lamp is off
This poses an increased risk of injury or even
fatal injury.
Move the front-passenger seat as far back as
possible. Always make sure that the shoulder
belt strap is correctly routed from the vehicle
belt sash guide to the shoulder belt guide on
the child restraint system. The shoulder belt
strap must be routed forwards and down-
wards from the vehicle belt sash guide. If nec- essary, adjust the vehicle belt sash guide and
the front-passenger seat accordingly. Always
observe the child restraint system manufac-
turer's installation instructions.
If OCS determines that:
RThe front-passenger seat is unoccupied, the
PASSENGER AIR BAG OFF indicator lamp
lights up after the system self-test and
remains lit. This indicates that the front-
passenger front air bag is deactivated.
RThe front-passenger seat is occupied by a
child of up to twelve months old, in a standard
child restraint system, the PASSENGER AIR
BAG OFF indicator lamp lights up after the
system self-test and remains lit. This indi-
cates that the front-passenger front air bag is
deactivated.
But even in the case of a twelve-month-old
child, in a standard child restraint system, the
PASSENGER AIR BAG OFF indicator lamp can
go out after the system self-test. This indi-
cates that the front-passenger front air bag is
activated. The result of the classification is
dependent on, among other factors, the child
restraint system and the child's stature. It is
recommended that you install the chi
ld
restraint system on a suitable rear seat.
RThe front-passenger seat is occupied by a
person of smaller stature (e.g. a teenager or
small adult), the PASSENGER AIR BAG OFF
indicator lamp lights up and remains lit after
the system self-test depending on the result
of the classification or, alternatively, goes out.
-If the PASSENGER AIR BAG OFF indicator
lamp is off, move the front-passenger seat
as far back as possible. Alternatively, a per-
son of smaller stature can sit on a rear seat.
-If the PASSENGER AIR BAG OFF indicator
lamp is lit, a person of smaller stature
should not use the front-passenger seat.
RThe front-passenger seat is occupied by an
adult or a person of adult stature, the
PASSENGER AIR BAG OFF indicator lamp
goes out after the system self-test. This indi-
cates that the front-passenger front air bag is
activated.
If children are traveling in the vehicle, be sure to
observe the notes on "Children in the vehicle"
(
Ypage 58).
When the occupant classification system (OCS)
is malfunctioning, the red 6restraint system
warning lamp in the instrument cluster and the
PASSENGER AIR BAG OFF indicator lamp light
up simultaneously. The front-passenger front air bag is deactivated in this case and does not
deploy during an accident. Have the Occupant
Classification System (OCS) checked and
repaired immediately at a qualified specialist
workshop. Mercedes-Benz recommends that
you visit a Mercedes-Benz Commercial Van Cen-
ter.
If the front-passenger seat, the seat cover or theseat cushion are damaged, have the necessary
repair work carried out at a qualified specialist
workshop. Mercedes-Benz recommends that
you visit a Mercedes-Benz Commercial Van Cen-
ter.
For safety reasons, Mercedes-Benz recom-
mends that you only use seat accessories that
have been approved by Mercedes-Benz.
If the driver's air bag depl oys, thi
s does not
mean that the front-passenger front air bag will
also deploy. The Occupant Classification Sys-
tem (OCS) categorizes the occupant on the
front-passenger seat. Depending on that result,
the front-passenger front air bag is either ena-
bled or deactivated.

Deployment of Emergency Tensioning
Devices and air bags
Important safety notes
GWARNING
The air bag parts are hot after an air bag has
been deployed. There is a risk of injury.
Do not touch the air bag parts. Have a
deployed air bag replaced at a qualified spe-
cialist workshop as soon as possible.
GWARNING
A deployed air bag no longer offers any pro-
tection and cannot provide the intended pro-
tection in an accident. There is an increased
risk of injury.
56Occupant safety
Safety

Have the vehicle towed to a qualified special-
ist workshop in order to have a deployed air
bag replaced.
It is important for your safety and that of your
passenger to have deployed air bags replaced
and to have any malfunctioning air bags
repaired. This will help to make sure the air bags
continue to perform their protective function for
the vehicle occupants in the event of a crash.
GWARNING
Emergency Tensioning Devices that have
deployed pyrotechnically are no longer opera-
tional and are unable to perform their inten-
ded protective function. This poses an
increased risk of injury or even fatal injury.
Have pyrotechnically triggered Emergency
Tensioning Devices replaced immediately at a
qualified specialist workshop.
If Emergency Tensioning Devices are triggered
or air bags are deployed, you will hear a bang,
and a small amount of powder may also be
released. The 6restraint system warning
lamp lights up.
Only in rare cases will the bang affect your hear-
ing. The powder that is released generally does
not constitute a health hazard, but it may cause
short-term breathing difficulties in people with
asthma or other respiratory problems. Provided
it is safe to do so, you should leave the vehicle
immediately or open the window in order to pre-
vent breathing difficulties.
Air bags and pyrotechnic Emergency Tensioning
Devices (ETDs) contain perchlorate material,
which may require special handling and regard
for the environment. National guidelines must
be observed during disposal. In California, see
www.dtsc.ca.gov/HazardousWaste/
Perchlorate/index.cfm.
Method of operation
During the first stage of a collision, the restraint
system control unit evaluates important physi-
cal data relating to vehicle deceleration or accel-
eration, such as:
Rduration
Rdirection
Rintensity Based on the evaluation of this data, the
restraint system control unit triggers the Emer-
gency Tensioning Devices during a frontal or
rear collision.
An Emergency Tensioning Device can only be
triggered, if:
Rthe ignition is switched on
Rthe components of the restraint system are
operational. You can find further information
under "Restraint system warning lamp"
(
Ypage 45)
Rthe seat belt buckle tongue has engaged in
the belt buckle of the respective front seat
If the restraint system control unit detects a
more severe accident, further components of
the restraint system are activated independ-
ently of each other in certain frontal collision
situations:
RFront air bags
RWindow curtain air bag, if the system deter-
mines that deployment can offer additional
protection to that provided by the seat belt
The front-passenger front air bag is activated or
deactivated depending on the person on the
front-passenger seat. The front-passenger front
air bag can only deploy in an accident if the
PASSENGER AIR BAG OFF indicator lamp is off.
Observe the information on the PASSENGER AIR
BAG OFF indicator lamp (
Ypage 46).
Your vehicle has two-stage front air bags. In the
first deployment stage, the front air bag is filled
with propellant gas. The front air bag is fully
deployed with the ma
ximum amount of propel-
lant gas if a second deployment threshold is
reached within a few milliseconds.
The activation threshold of the Emergency Ten-
sioning Devices and the air bags is determined
by evaluating the rate of vehicle deceleration or
acceleration which occurs at various points in
the vehicle. This process is pre-emptive in
nature. Deployment should take place in good
time at the start of the collision.
The rate of vehicle deceleration or acceleration
and the direction of the force are essentially
determined by:
Rthe distribution of forces during the collision
Rthe collision angle
Rthe deformation characteristics of the vehicle
Rthe characteristics of the object with which
the vehicle has collided
Factors which can only be seen and measured
after a collision has occurred do not play a deci-

Pets in the vehicle
GWARNING
If you leave animals unattended or unsecured
in the vehicle, they could press buttons or
switches, for example.
As a result, they could:
Ractivate vehicle equipment and become
trapped, for example
Ractivate or deactivate systems, thereby
endangering other road users
Unsecured animals could also be flung around
the vehicle in the event of an accident or sud-
den steering or braking, thereby injuring vehi-
cle occupants. There is a risk of an accident
and injury.
Never leave animals unattended in the vehi-
cle. Always secure animals properly during
the journey, e.g. use a suitable animal trans-
port box.
Driving safety systems
Overview
In this section, you will find information about
the following driving safety systems:
REBD ( Electronic Brake Force Distribution)
RABS ( Anti-lock Braking System)
RBAS ( Brake Assist System)
RESP®(E lectronic Stability Program)
Important safety notes
If you fail to adapt your driving style or if you are
inattentive, the driving safety systems can nei-
ther reduce the risk of accident nor override the
laws of physics. Driving safety systems are
merely aids designed to assist driving. You are
responsible for the distance to the vehicle in
front, for vehicle speed, braking in good time
and for staying in your lane. Always adapt your driving style to the prevailing road and weather
conditions and maintain a sufficient, safe dis-
tance from other road users. Drive carefully.
Please note that the driving safety systems
described only work optimally when:
Rthere is adequate contact between the tires
and the road surface
Ryou use winter tires (M+S tires), with snow
chains if necessary, when the road conditions
are wintry
Rthe speed information determined by the
vehicle is within the legally prescribed display
accuracy
Pay particular attention to the information
regarding tires, tire tread and winter operation
under "Wheels and tires" (
Ypage 277).
ABS (Anti-lock Braking System)
General notes
ABS regulates brake pressure in such a way that the wheels do not lock when you brake. This
allows you to continue steering the vehicle when
braking.
The ò warning lamp in the instrument cluster
lights up when the ignition is switched on. The
lamp goes out when the engine starts running.
Important safety notes
Observe the important safety guidelines for the
driving safety system (Ypage 64).
ABS works from a speed of about 5 mph
(8 km/h), regardless of road-surface conditions. ABS works on slippery surfaces, even when you
only brake gently.
GWARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking charac-
teristics may be severely impaired. Addition-
ally, further driving safety systems are deac-
tivated. There is an increased danger of skid-
ding and accidents.
Drive on carefully. Have ABS checked imme-
diately at a qualified specialist workshop.
If ABS is malfunctioning, the òwarning lamp
(
Ypage 222) lights up while the engine is run-
ning and the display shows a message:

Ron vehicles without steering wheel buttons
(Ypage 190)
Ron vehicles with steering wheel buttons
(Ypage 204)
BAS, Hill Start Assist and ESP®and its driving
safety systems and other driving systems also
fail. Observe the notes on the òwarning
lamp and the display messages.
Braking
If ABS intervenes when braking, you will feel a
pulsating in the brake pedal.
The pulsating brake pedal can be an indication
of hazardous road conditions and functions as a
reminder to take extra care while driving.
XIf ABS intervenes: continue to depress the
brake pedal with force until the braking sit-
uation is over.
XTo make a full brake application: depress
the brake pedal with full force.
BAS (Brake Assist System)
General notes
BAS operates in emergency braking situations.
If you depress the brake pedal quickly, BAS
automatically boosts the braking force, thus
shortening the stopping distance.
Important safety notes
Observe the important safety guidelines for the
driving safety system (Ypage 64).
GWARNING
If BAS is malfunctioning, the braking distance
in an emergency braking situation is
increased. There is a risk of an accident.
In an emergency braking situation, depress
the brake pedal with full force. ABS prevents
the wheels from locking.
If BAS is malfunctioning, the ÷warning lamp
lights up while the engine is running
(
Ypage 222) and the display shows a message:
Ron vehicles without steering wheel buttons
(Ypage 194)

(Ypage 208)
Brakes
XKeep the brake pedal firmly depressed until
the emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated.
EBD (electronic brake force distribu-
tion)
General notes
EBD monitors and controls the brake pressure
to the rear wheels. This enables EBD to improve
handling during braking.
Important safety notes
Observe the important safety guidelines for the
driving safety system (Ypage 64).
GWARNING
If EBD is malfunctioning, the rear wheels can
lock, e.g. under full braking. This increases the
risk of skidding and an accident.
You should therefore adapt your driving style
to the different handling characteristics. Have
the brake system checked at a qualified spe-
cialist workshop.
If EBD is malfunctioning, the $warning lamp
(
Ypage 221) lights up while the engine is run-
ning and the display shows a message.

Other driving systems and driving safety sys-
tems then also fail.
ESP®(Electronic Stability Program)
General notes
ESP®monitors driving stability and detects a
tendency of the vehicle to understeer or over-
steer (skidding) in good time. If ESP
®detects
that the vehicle is deviating from the direction
desired by the driver, one or more wheels are
braked to stabilize the vehicle. The engine out-

put is also modified to keep the vehicle on the
desired course within physical limits. ESP®can
also stabilize the vehicle during braking.
ESP
®also monitors traction, i.e. power trans-
mission between the tires and the road surface.
The integrated traction control supports you
when pulling away or accelerating on wet, slip-
pery or slick roads. Should the drive wheels spin,
traction control brakes them individually. In
addition, greater drive torque is transmitted to
the wheel or wheels with traction. If traction on
the road surface is not sufficient, even ESP
®will
not allow you to pull away without difficulty. The
type of tires and total weight of the vehicle as
well as the gradient of the road also play a cru-
cial role. Traction control remains active if you
deactivate ESP
®.
If the h warning lamp in the instrument clus-
ter goes out before beginning the journey, ESP
®
is automatically active.
The h warning lamp in the instrument cluster
flashes when ESP
®intervenes:
XDo not deactivate ESP®under any circum-
stances.
Xwhen driving off, apply as little throttle as
possible.
Xadapt your speed and driving style to the pre-
vailing road conditions.
Important safety notes
Observe the important safety guidelines for the
driving safety system (Ypage 64).
GWARNING
If ESP
®is malfunctioning it will not provide
any vehicle stabilization. There is an increased
risk of skidding or of an accident.
Exercise caution when continuing to drive.
Have ESP
®checked at a qualified specialist
workshop.
!Do not run the vehicle on a roller dynamom-
eter (e.g. for performance tests). If you must
operate the vehicle on a roller dynamometer,
please consult a qualified specialist workshop
in advance. You could otherwise damage the
drive train or the brake system.
If ESP
®is malfunctioning, the hwarning
lamp (Ypage 222) lights up continuously while the engine is running and the display shows a
message.

Trailer stabilization
Observe the important safety guidelines for the
driving safety system (Ypage 64).
GWARNING
If road and weather conditions are poor,
trailer stabilization will not be able to prevent
the vehicle/trailer combination from swerv-
ing. Trailers with a high center of gravity can
tip over before ESP
®can detect this. There is
a risk of an accident.
Always adapt your driving style to the prevail-
ing road and weather conditions.
ESP
®trailer stabilization counteracts critical
driving situations in good time and thereby pro- vides considerable assistance when driving with
a trailer. Trailer stabilization is part of ESP
®.
If the sensor system and evaluation logic detect
trailer swinging movements, ESP
®trailer stabi-
lization firstly brakes individual vehicle wheels in
a targeted manner. It thus counteracts swinging
movements. If the swinging movements do not
stop, the vehicle is braked until the vehicle/ trailer combination is stabilized. If necessary,
the vehicle's engine output is limited.
If your vehicle with trailer (vehicle/trailer com-
bination) starts to swerve, you will be able to
stabilize the vehicle/trailer combination only by
braking. ESP
®trailer stabilization helps you to
stabilize the vehicle/trailer combination in this
s
ituation.
ESP
®trailer stabilization is activated above
speeds of about 40 mph (65 km/h).
If ESP
®is switched off or deactivated because of
a malfunction, the trailer stabilization system
will not function.
Crosswind Assist
Observe the important safety guidelines for the
driving safety system (Ypage 64).
Strong crosswind gusts can impair the road-
holding of your vehicle when driving straight
ahead. The Crosswind Assist function integra-
ted in ESP
®reduces these impairments.
Depending on the direction and intensity of the
side wind, Crosswind Assist intervenes auto-
matically. ESP
®intervenes with stabilizing brak-
ing to assist you in keeping the vehicle in the
lane. When Crosswind Assist intervenes, the
display shows the traffic sign for strong side
winds and the Crosswind Assist
message.
Crosswind Assist is activated automatically
above a vehicle speed of approx. 50 mph
(80 km/h) when the vehicle is driving straight
ahead or cornering gently.
Crosswind Assist does not react:
Rin the event of severe jolts and vibrations, e.g.
when driving over uneven surfaces or pot-
holes
Rwhen grip is reduced, e.g. on snow or ice or
when hydroplaning
Crosswind Assist does not work if ESP
®is deac-
tivated or disabled because of a malfunction.
